How to fix "Can't perform a React state update on an unmounted component." error in React Native
|
<p>I'm fetching data in my local database (sqlite) and updating the state, and this error is appearing: </p>
<blockquote>
<p>Can't perform a React state update on an unmounted component. This is a >no-op, but it indicates a memory leak in your application. To fix, >cancel all subscriptions and asynchronous tasks in the >componentWillUnmount method.</p>

How can I implement this POST request using HTTParty?
|
<p>I am having difficulty making a POST request to an API endpoint using Ruby's HTTParty library. The API I'm interacting with is the <a href="https://github.com/gittip/www.gittip.com#api">Gittip API</a> and their endpoint requires authentication. I have been able to successfully make an authenticated GET request using HTTParty.</p>
<p>You can see in the example code:</p>
<pre><code>user = "gratitude_test"
api_key = "5962b93a-5bf7-4cb6-ae6f-aa4114c5e4f2"
# I have included real credentials since the above is merely a test account.
HTTParty.get("https://www.gittip.com/#{user}/tips.json",
{ :basic_auth => { :username => api_key } })
</code></pre>
<p>That request works and returns the following as expected:</p>
<pre><code>[
{
"amount" => "1.00",
"platform" => "gittip",
"username" => "whit537"
},
{
"amount" => "0.25",
"platform" => "gittip",
"username" => "JohnKellyFerguson"
}
]
</code></pre>
<p>However, I have been unable to make a successful POST request using HTTParty. The Gittip API describes making a POST request using curl as follows:</p>
<pre><code>curl https://www.gittip.com/foobar/tips.json \
-u API_KEY: \
-X POST \
-d'[{"username":"bazbuz", "platform":"gittip", "amount": "1.00"}]' \
-H"Content-Type: application/json"
</code></pre>
<p>I have tried (unsuccessfully) structuring my code using HTTParty as follows:</p>
<pre><code>user = "gratitude_test"
api_key = "5962b93a-5bf7-4cb6-ae6f-aa4114c5e4f2"
HTTParty.post("https://www.gittip.com/#{user}/tips.json",
{
:body => [ { "amount" => "0.25", "platform" => "gittip", "username" => "whit537" } ],
:basic_auth => { :username => api_key },
:headers => { 'Content-Type' => 'application/json' }
})
</code></pre>
<p>The first argument is the url and the second argument is an options hash. When I run the code above, I get the following error:</p>
<pre><code>NoMethodError: undefined method `bytesize' for [{"amount"=>"0.25", "platform"=>"gittip", "username"=>"whit537"}]:Array
from /Users/John/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/2.0.0/net/http/generic_request.rb:179:in `send_request_with_body'
</code></pre>
<p>I have tried various other combinations of structuring the API call, but can't figure out how to get it to work. Here's another such example, where I do not user an array as part of the body and convert the contents <code>to_json</code>.</p>
<pre><code>user = "gratitude_test"
api_key = "5962b93a-5bf7-4cb6-ae6f-aa4114c5e4f2"
HTTParty.post("https://www.gittip.com/#{user}/tips.json",
{
:body => { "amount" => "0.25", "platform" => "gittip", "username" => "whit537" }.to_json,
:basic_auth => { :username => api_key },
:headers => { 'Content-Type' => 'application/json' }
})
</code></pre>
<p>Which returns the following (a 500 error):</p>
<pre><code><html>
<head>
<title>500 Internal Server Error</title>
</head>
<body>\n Internal server error, program!\n <pre></pre>
</body>
</html>
</code></pre>
<p>I'm not really familiar with curl, so I'm not sure if I am incorrectly translating things to HTTParty.</p>
<p>Any help would be appreciated. Thanks.</p>

No more post back after file download in sharepoint
|
<p>I tried to download a file from sharepoint.
But after I download this file, I can't click on other buttons.
What is wrong with my coding?</p>
<p><strong>This is my first way.</strong></p>
<blockquote>
<pre><code> Response.AppendHeader("content-disposition", "attachment; filename= " + fileName);
Response.ContentType = "text/plain";
Response.WriteFile(Server.MapPath("~/" + fileName));
Response.End();
</code></pre>
</blockquote>
<p><strong>This is my second way</strong></p>
<blockquote>
<pre><code> byte[] bytes = System.IO.File.ReadAllBytes("D:\\" + fileName);
Response.ClearContent();
Response.ClearHeaders();
Response.AddHeader("Content-Type", "application/octet-stream");
Response.AddHeader("Content-Length", bytes.Length.ToString());
Response.AddHeader("content-disposition", "attachment; filename= " + fileName);
Response.BinaryWrite(bytes);
Response.Flush();
Response.End();
</code></pre>
</blockquote>
<p>I even comment Response.End() but still the same result.</p>
<p>Is there any other way I should tried?</p>
<p>Any help would be really appreciated.
In fact, I posted this question a few days ago, but only one gave me my second way to try but it is still not working.</p>

MVC 4 Bootstrap Modal Edit \ Detail
|
<p>Hoping someone might be able to help me with something I am experimenting with in MVC 4 using bootstrap.</p>
<p>I have a strongly-typed index view which displays items in a table along with edit and delete action icons in each line.</p>
<pre><code>@model IEnumerable<Models.EquipmentClass>
....
@foreach (var item in Model)
{
<tbody>
<tr>
<td>
@item.ClassId
</td>
<td>
@item.ClassName
</td>
<td>
<a href=@Url.Action("Edit", "EquipmentClass", new { id = item.ClassId })>
<i class="icon-edit"></i>
</a>
<a href=@Url.Action("Delete", "EquipmentClass", new { id = item.ClassId })>
<i class="icon-trash"></i>
</a>
</td>
</tr>
</tbody>
} <!-- foreach -->
</code></pre>
<p>The EquipmentClass controller returns the Edit view for the selected item based on the id. All great and as expected at this point</p>
<pre><code>public ViewResult Edit(int id)
{
return View(equipmentclassRepository.Find(id));
}
</code></pre>
<p>What I would like to know is how to open the edit form in a bootstrap modal dialog.</p>
<p>I could try and substitute the edit action in the table with the following and then have a modal div at the bottom of the view but how do I pass in the ID of the selected item and which html helper should I use in the modal section?</p>
<pre><code><!-- replaced table action -->
<a class="btn pull-right" data-toggle="modal" href="#myModal" >Details</a>
....
<!-- modal div -->
<div class="modal hide fade in" id="myModal" )>
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h3>Modal header</h3>
</div>
<div class="modal-body">
@Html.Partial("Edit")
</div>
<div class="modal-footer">
<a href="#" class="btn" data-dismiss="modal">Close</a>
<a href="#" class="btn btn-primary">Save changes</a>
</div>
</div>
</code></pre>
<p>I'd greatly appreciate any advice, many thanks</p>

How to install weblogic maven plugin for weblogic v12.1.2 (12c)?
|
<p>To install weblogic application server I decompressed 2 files I got from or oracle using these links:</p>
<p><a href="http://download.oracle.com/otn/nt/middleware/12c/wls/1212/wls1212_dev.zip" rel="noreferrer">http://download.oracle.com/otn/nt/middleware/12c/wls/1212/wls1212_dev.zip</a>
<a href="http://download.oracle.com/otn/nt/middleware/12c/wls/1212/wls1212_dev_supplemental.zip" rel="noreferrer">http://download.oracle.com/otn/nt/middleware/12c/wls/1212/wls1212_dev_supplemental.zip</a></p>
<p>..found on <a href="http://www.oracle.com/technetwork/middleware/ias/downloads/wls-main-097127.html" rel="noreferrer">this page</a>.</p>
<p>I simply decompressed both files and they automatically decompress to the same folder. setting the <code>MW_HOME</code> and <code>JAVA_HOME</code> environment variables to point to the decompressed folder and Java 7 JDK locations respectively, I ran the <code>configure.cmd</code> file and it ended successfully.</p>
<p>The problem is that I can't reach the same result <a href="http://docs.oracle.com/middleware/1212/wls/WLPRG/maven.htm" rel="noreferrer">this page</a> shows if I follow the instructions on it. I summarized these instructions here:
(<code>ORACLE_HOME</code> is identical to <code>MW_HOME</code>, they both point to the installation folder.)</p>
<pre><code>%ORACLE_HOME%/wlserver/server/bin/setWLSEnv
cd %ORACLE_HOME%/oracle_common/plugins/maven/com/oracle/maven/oracle-maven-sync/12.1.2
mvn install:install-file -DpomFile=oracle-maven-sync.12.1.2.pom -Dfile=oracle-maven-sync.12.1.2.jar

mvn help:describe -DgroupId=com.oracle.weblogic -DartifactId=weblogic-maven-plugin -Dversion=12.1.2-0-0
</code></pre>
<p>Where <code>oracle-maven-sync.oracleHome</code> is <code>The path to the Oracle home that you wish to populate the Maven repository from.</code>. Its basically the Weblogic directory having <code>wlserver</code> directory in it.</p>
<p>The problem is that the last line (the line that asks the installed plugin for description), shows the following error message (Ignore the masked IPs, I masked them manually in this question):</p>

<p>What makes me think that this is NOT a network problem, is that I've successfully installed this plugin before, but I can't remember how exactly so may be I'm missing some steps ?</p>
<p>How can I resolve this please ? My goal is to be able to refer to weblogic's libraries from maven as a <strong>dependency</strong> in the following way:</p>
<pre><code><dependency>
<groupId>com.oracle.weblogic</groupId>
<artifactId>weblogic-server-pom</artifactId>
<version>12.1.2-0-0</version>

Spring security oauth2 and form login configuration
|
<p>My project consists exposes two different parts, a JSF admin panel and a RESTfull service.
I am trying to setup spring security to use different authentication methods depending on the URL the user navigates.</p>
<p>The requirements are</p>
<ul>
<li>Users navigating to the JSF page get a login screen where they authentication using form authentication.</li>
<li>Users navigating to the REST service use OAuth2 implicit authentication with basic authentication for the token granting.</li>
</ul>
<p>The seperate configurations work by themselves, the problem is when I try to combine both of them in one configuration, in that case it seems like the REST provider gets in the way and authenticates each request even if the requests go to the admin url (this is documented from spring security ordering).</p>
<p>My sample configurations are as shown:</p>
<ul>
<li><p>For the form login (JSF)</p>

Show splash screen when page loads, but at least for x seconds
|
<p>I have a div with a splashscreen element. This element will be hidden on page load. However, I also want to make sure the splash screen is shown for at least x seconds.</p>
<p>I know this is not all supposed to be formatted as code but the auto formatter made me do it.</p>
<p>To use logic:
Show splash screen for at least x seconds.
If the page is loaded by that time hide this div.</p>
<p>This code is the part where it hides the div as soon as the page is loaded.</p>
<pre><code><!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js">

Spring Security - Token based API auth & user/password authentication
|
<p>I am trying to create a webapp that will primarily provide a REST API using Spring, and am trying to configure the security side.</p>
<p>I am trying to implement this kind of pattern: <a href="https://developers.google.com/accounts/docs/MobileApps" rel="nofollow noreferrer">https://developers.google.com/accounts/docs/MobileApps</a> (Google have totally changed that page, so no longer makes sense - see the page I was referring to here: <a href="http://web.archive.org/web/20130822184827/https://developers.google.com/accounts/docs/MobileApps" rel="nofollow noreferrer">http://web.archive.org/web/20130822184827/https://developers.google.com/accounts/docs/MobileApps</a>)</p>
<p>Here is what I need to accompish:</p>
<ul>
<li>Web app has simple sign-in/sign-up forms that work with normal spring user/password authentication (have done this type of thing before with dao/authenticationmanager/userdetailsservice etc)</li>
<li>REST api endpoints that are stateless sessions and every request authenticated based ona token provided with the request</li>
</ul>
<p>(e.g. user logins/signs up using normal forms, webapp provides secure cookie with token that can then be used in following API requests)</p>
<p>I had a normal authentication setup as below:</p>
<pre><code>@Override protected void configure(HttpSecurity http) throws Exception {
http
.csrf()
.disable()
.authorizeRequests()
.antMatchers("/resources/**").permitAll()
.antMatchers("/mobile/app/sign-up").permitAll()
.antMatchers("/v1/**").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/")
.loginProcessingUrl("/loginprocess")
.failureUrl("/?loginFailure=true")
.permitAll();
}
</code></pre>
<p>I was thinking of adding a pre-auth filter, that checks for the token in the request and then sets the security context (would that mean that the normal following authentication would be skipped?), however, beyond the normal user/password I have not done too much with token based security, but based on some other examples I came up with the following:</p>
<p>Security Config:</p>
<pre><code>@Override protected void configure(HttpSecurity http) throws Exception {
http
.csrf()
.disable()
.addFilter(restAuthenticationFilter())
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
.exceptionHandling().authenticationEntryPoint(new Http403ForbiddenEntryPoint()).and()
.antMatcher("/v1/**")
.authorizeRequests()
.antMatchers("/resources/**").permitAll()
.antMatchers("/mobile/app/sign-up").permitAll()
.antMatchers("/v1/**").permitAll()
.anyRequest().authenticated()
.and()
.formLogin()
.loginPage("/")
.loginProcessingUrl("/loginprocess")
.failureUrl("/?loginFailure=true")
.permitAll();
}
</code></pre>
<p>My custom rest filter:</p>
<pre><code>public class RestAuthenticationFilter extends AbstractAuthenticationProcessingFilter {
public RestAuthenticationFilter(String defaultFilterProcessesUrl) {
super(defaultFilterProcessesUrl);
}
private final String HEADER_SECURITY_TOKEN = "X-Token";
private String token = "";
@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) req;
HttpServletResponse response = (HttpServletResponse) res;
this.token = request.getHeader(HEADER_SECURITY_TOKEN);
//If we have already applied this filter - not sure how that would happen? - then just continue chain
if (request.getAttribute(FILTER_APPLIED) != null) {
chain.doFilter(request, response);
return;
}
//Now mark request as completing this filter
request.setAttribute(FILTER_APPLIED, Boolean.TRUE);
//Attempt to authenticate
Authentication authResult;
authResult = attemptAuthentication(request, response);
if (authResult == null) {
unsuccessfulAuthentication(request, response, new LockedException("Forbidden"));
} else {
successfulAuthentication(request, response, chain, authResult);
}
}
/**
* Attempt to authenticate request - basically just pass over to another method to authenticate request headers
*/
@Override public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException, IOException, ServletException {
AbstractAuthenticationToken userAuthenticationToken = authUserByToken();
if(userAuthenticationToken == null) throw new AuthenticationServiceException(MessageFormat.format("Error | {0}", "Bad Token"));
return userAuthenticationToken;
}
/**
* authenticate the user based on token, mobile app secret & user agent
* @return
*/
private AbstractAuthenticationToken authUserByToken() {
AbstractAuthenticationToken authToken = null;
try {
// TODO - just return null - always fail auth just to test spring setup ok
return null;
} catch (Exception e) {
logger.error("Authenticate user by token error: ", e);
}
return authToken;
}
</code></pre>
<p>The above actually results in an error on app startup saying: <code>authenticationManager must be specified</code>
Can anyone tell me how best to do this - is a pre_auth filter the best way to do this?</p>
<hr>
<p><strong>EDIT</strong></p>

Can't change back button title but I can hide it
|
<p>I'm developing an <strong>iPhone</strong> application with <strong>latest SDK</strong> and <strong>XCode 4.2</strong></p>
<p>I use a UINavigationController, and to show a new ViewController I do this on AppDelegate.m:</p>
<pre><code> - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
{
self.viewController = [[ViewController alloc] initWithNibName:@"ViewController_iPhone" bundle:nil];
}
else
{
self.viewController = [[ViewController alloc] initWithNibName:@"ViewController_iPad" bundle:nil];
}
self.viewController.title = NSLocalizedString(@"MAIN", nil);
navController = [[UINavigationController alloc] initWithRootViewController:self.viewController];
navController.navigationBar.tintColor = [UIColor darkGrayColor];
self.window.rootViewController = navController;
[self.window makeKeyAndVisible];
return YES;
}
- (void) openDocumentation
{
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
{
docViewController = [[DocumentationViewController alloc] initWithNibName:@"DocumentationViewController_iPhone" bundle:nil];
}
else
{
docViewController = [[DocumentationViewController alloc] initWithNibName:@"DocumentationViewControllerr_iPad" bundle:nil];
}
docViewController.title = NSLocalizedString(@"DOCUMENTATION", nil);
self.viewController.navigationItem.backBarButtonItem.title = @"Back";
[navController pushViewController:docViewController animated:YES];
}
</code></pre>
<p>On <code>DocumentationViewController.m</code> I do this:</p>
<pre><code>- (void) viewWillAppear:(BOOL)animated
{
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Back"
style:UIBarButtonItemStylePlain target:nil action:nil];
self.navigationItem.backBarButtonItem = backButton;
}
</code></pre>
<p>But it doesn't change back button title.</p>
<p>I move that code to viewDidLoad:</p>
<pre><code>- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Back"
style:UIBarButtonItemStylePlain target:nil action:nil];
self.navigationItem.backBarButtonItem = backButton;
}
- (void) viewWillAppear:(BOOL)animated
{
}
</code></pre>
<p>But still doesn't work.</p>
<p>And this doesn't work either:</p>
<pre><code>- (void) viewWillAppear:(BOOL)animated
{
self.navigationItem.backBarButtonItem.title = @"Back";
}
</code></pre>
<p>But if I do this, to test if I can't access back button:</p>
<pre><code>- (void) viewWillAppear:(BOOL)animated
{
self.navigationItem.hidesBackButton = YES;
}
</code></pre>
<p>It works!! And hides back button.</p>
<p>What am I doing wrong?</p>

Should FILTER be used inside or outside of SUMMARIZE?
|
<p>I have these two queries:</p>
<pre><code>EVALUATE
FILTER (
SUMMARIZE (
'Sales',
Products[ProductName],
'Calendar'[CalendarYear],
"Total Sales Amount", SUM ( Sales[SalesAmount] ),
"Total Cost", SUM ( 'Sales'[TotalProductCost] )
),
Products[ProductName] = "AWC Logo Cap"
)
ORDER BY
Products[ProductName],
'Calendar'[CalendarYear] ASC
</code></pre>
<p>and this:</p>
<pre><code>EVALUATE
SUMMARIZE (
FILTER ( 'Sales', RELATED ( Products[ProductName] ) = "AWC Logo Cap" ),
Products[ProductName],
'Calendar'[CalendarYear],
"Total Sales Amount", SUM ( Sales[SalesAmount] ),
"Total Cost", SUM ( 'Sales'[TotalProductCost] )
)
ORDER BY
Products[ProductName],
'Calendar'[CalendarYear] ASC
</code></pre>
<p>Both return the following:</p>
<p><a href="https://i.stack.imgur.com/3qrdO.png" rel="noreferrer"><img src="https://i.stack.imgur.com/3qrdO.png" alt="enter image description here"></a></p>
<p>The only difference between the two queries is the positioning of the FILTER function - which is better practice and why?</p>
<hr>
<p>note</p>
<p>So looking at the two sqlbi articles referenced by Alex we can do either of the following to potentially make things more performant but I'm still unsure if the FILTER function should happen inside or outside the other syntax:</p>
<pre><code>EVALUATE
FILTER (
ADDCOLUMNS (
SUMMARIZE ( 'Sales', Products[ProductName], 'Calendar'[CalendarYear] ),
"Total Sales Amount", CALCULATE ( SUM ( Sales[SalesAmount] ) ),
"Total Cost", CALCULATE ( SUM ( 'Sales'[TotalProductCost] ) )
),
Products[ProductName] = "AWC Logo Cap"
)
ORDER BY
Products[ProductName],
'Calendar'[CalendarYear] ASC
</code></pre>
<p>And using the 'SUMMARIZECOLUMNS' function:</p>
<pre><code>EVALUATE
FILTER (
SUMMARIZECOLUMNS (
Products[ProductName],
'Calendar'[CalendarYear],
"Total Sales Amount", SUM ( Sales[SalesAmount] ),
"Total Cost", SUM ( 'Sales'[TotalProductCost] )
),
Products[ProductName] = "AWC Logo Cap"
)
ORDER BY
Products[ProductName],
'Calendar'[CalendarYear] ASC
</code></pre>
<hr>
<p>note2 </p>
<p>Looks like SUMMARIZECOLUMNS has a built in FILTER parameter so I'd guess that this is the best way to go to guard against performance issues:</p>
<pre><code>EVALUATE
SUMMARIZECOLUMNS (
Products[ProductName],
'Calendar'[CalendarYear],
FILTER ( 'Products', Products[ProductName] = "AWC Logo Cap" ),
"Total Sales Amount", SUM ( Sales[SalesAmount] ),
"Total Cost", SUM ( 'Sales'[TotalProductCost] )
)
ORDER BY
Products[ProductName],
'Calendar'[CalendarYear] ASC
</code></pre>

WEBPACK_IMPORTED_MODULE_13___default(...) is not a function
|
<p>Context : I am building a small library (let's call it myLibrary here) using TypeScript and Webpack. I built it, imported it in a react application but the react application crash.</p>
<p><strong>Library side</strong></p>
<p>My main entry point (index.ts) has a default export as such :</p>
<pre><code>import wrapper from "./wrapper";
export default wrapper;
</code></pre>
<p>And my wrapper file exposes a default export which is a function (wrapper.ts) :</p>
<pre><code>const create = () => {
// Some functions
return {
init,
close,
getBase,
setBase
}
}
export default create;
</code></pre>
<p>The library pass all the unit tests easily.</p>
<p><strong>React application side</strong></p>
<p>After building and when importing my library in a React application, I have no Typescript error but my React app crashes with the following message :</p>
<pre><code>TypeError: myLibrary__WEBPACK_IMPORTED_MODULE_13___default(...) is not a function
</code></pre>
<p>After calling my library like that :</p>
<pre><code>import createAPI from "myLibrary";
const api = createAPI(); // Crash here even though I should have a nice object containing my functions
</code></pre>
<p>It's really strange as TS really compiled nicely to JS without any warnings.</p>
<p>My library wepback config (4.43.0) which I use to build with command <code>webpack --config webpack.config.js</code>:</p>
<pre><code>const path = require('path');
module.exports = {
mode: "production",
entry: "./src/index.ts",
output: {
filename: "index.js",
path: path.resolve(__dirname, 'dist'),
},
resolve: {
extensions: [".ts", ".js"]
},
module: {
rules: [
{ test: /\.tsx?$/, loader: "ts-loader" }
]
}
}
</code></pre>
<p>My library TS config (3.7.3) :</p>
<pre><code>{
"compilerOptions": {
"outDir": "dist",
"target": "es5",
"module": "CommonJS",
"lib": ["dom", "dom.iterable", "esnext"],
"sourceMap": true,
"allowJs": true,
"jsx": "preserve",
"declaration": true,
"moduleResolution": "node",
"forceConsistentCasingInFileNames": true,
"esModuleInterop": true,
"allowSyntheticDefaultImports": true,
"experimentalDecorators": true
},
"include": ["src"]
}
</code></pre>
<p>Any help would be greatly appreciated :)</p>
<p>EDIT :
After updating default export to named export :</p>
<pre><code>import { createAPI } from "myLibrary";
const api = createAPI();
</code></pre>
<p>I got a new error</p>
<pre><code>TypeError: Object(...) is not a function
</code></pre>
<p>And when I try to <code>console.log(typeof createAPI);</code> I got an undefined, which should not be possible as my tests are passing and TS doesn't complain.</p>

Email composure iOS 8

<p>I'm trying to open email composure in iOS 8 from Xcode 6, but getting an error. The same code is working fine if I'm trying from Xcode 5. Later I downloaded a sample code from apple developer portal: </p>

[picker setToRecipients:toRecipients];
[picker setCcRecipients:ccRecipients];
[picker setBccRecipients:bccRecipients];

// Fill out the email body text
NSString *emailBody = @"It is raining in sunny California!";
[picker setMessageBody:emailBody isHTML:NO];
[self presentViewController:picker animated:YES completion:NULL];

Submit a php form and display its result on div without reloading page
|
<p>First of all, thank you for your kind help. </p>
<p>I have tried almost everything I found on stackoverflow but I cannot get this to work.</p>
<p>I created a form to send a text to the webmaster (instead of an email). So I have my index.php file </p>
<pre><code> <style>
.result{
padding: 20px;
font-size: 16px;
background-color: #ccc;
color: #fff;
}
</style>
<form id="contact-form" method="post">
<div>
<input type="text" id="fullname" name="fullname" value="" placeholder="Name" required="required" autofocus="autofocus" autocomplete="off" />
</div>
<div>
<input type="email" id="email" name="email" value="" placeholder="example@yourdomain.com" required="required" autocomplete="off" />
</div>
<div>
<textarea id="message" name="message" value="" placeholder="20 characters max." required="required" maxlength="50" autocomplete="off" ></textarea>
</div>
<div>
<input type="submit" value="Submit" id="submit-button" name="submit" />
*indicates a required field
</div>
</form>
<div class="result"></div>
</code></pre>
<p>And this is my jquery</p>
<pre><code><script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script>
$(document).ready(function(){
$('#contact-form').submit(function() {
$.ajax({
type:"POST",
url:"sendtext.php",
data: $("#contact-form").serialize(),
success: function(response){$(".result").appendTo(response)}
});
//return false;
});
});
</script>
</code></pre>
<p>The script does not work. If I put <code>action = sendtext.php</code> in the <code><form></code> it will work perfectly but it will take me to sendtext.php and <code>echo</code> the message.</p>
<p>What I want is to show the <code>echo</code> in the <code><div class="result"></div></code>.</p>
<p>Again thank you for your help.</p>
<hr>
<p><strong>UPDATE # 1</strong>
After a few comments...</p>
<p>this is what I have so far...</p>
<pre><code><script>
$(document).ready(function(){
$('#contact-form').submit(function(e) {
e.preventDefault();
$.ajax({
type:"POST",
url:"sendtext.php",
data: $("#contact-form").serialize(),
success: function(response){$(".result").append(response)}
});
//return false;
});
});
</script>
</code></pre>
<hr>
<p><strong>Update 2</strong></p>
<p>After reading all the comments and try different options, no success just yet! I did what @guy suggested, and it worked but I want to use <code>form</code> and <code>submit</code>.</p>
<p>Again, I appreciate all your time you put to help me out. Thank you!</p>

how to install node js canvas on windows
|
<p>I'm trying to get working canvas on node js. I'm using Windows Vista. After basic approach <code>npm install canvas</code> failed (see error below), I have looked up some tutorials, here is what I have tried:</p>
<p>sources:<br>
<a href="https://github.com/benjamind/delarre.docpad/blob/master/src/documents/posts/installing-node-canvas-for-windows.html.md" rel="noreferrer">installing-node-canvas-for-windows</a><br>
<a href="https://github.com/LearnBoost/node-canvas/wiki/Installation---Windows" rel="noreferrer">LearnBoost/node-canvas/wiki/Installation---Windows</a></p>
<ul>
<li>I have installed older Python (2.7.5) and add it to PATH (and remove Python 3.2. from PATH) </li>
<li>I have checked that I do have Microsoft Visual Studio 2010 Professional installed</li>
<li>I have downloaded the 'all in one' GTK package from <a href="http://ftp.gnome.org/pub/gnome/binaries/win32/gtk+/2.24/gtk+-bundle_2.24.10-20120208_win32.zip" rel="noreferrer">http://ftp.gnome.org/pub/gnome/binaries/win32/gtk+/2.24/gtk+-bundle_2.24.10-20120208_win32.zip</a>, unziped it in C:\GTK\ and add 'C:\GTK\bin' to PATH</li>
</ul>
<p>log in console (after running <code>npm install canvas</code> in cmd):<br>
log contains several warnings, I don't thing these are the problem - it is mostly something like 'conversion from double to float', and one error marked in red color:</p>
<pre><code>init.cc
d:\pathToApp\node_modules\canvas\src\PNG.h(5): fatal error C1083: Cannot
open include file: 'cairo.h': No such file or directory [d:\pathToApp\n
ode_modules\canvas\build\canvas.vcxproj]
</code></pre>
<p>And at the very end of log there is:</p>
<pre><code>gyp ERR! build error
gyp ERR! stack Error: `C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild.exe
` failed with exit code: 1
gyp ERR! stack at ChildProcess.onExit (C:\Program Files\nodejs\node_modules\

gyp ERR! node-gyp -v v0.10.9
gyp ERR! not ok
npm ERR! weird error 1
npm ERR! not ok code 0
</code></pre>
<p>After that, nothing appeared in node-module folder (no canvas subdirectory, npm after unsuccessful installation removed the subdirectory).</p>
<p>So I have also tried to download canvas module manually from github, unzip it in node-modules and then run <code>node-gyp configure</code> in node-modules/canvas with success, and <code>node-gyp build</code>, which unfortunatelly gave me the same error <code>Cannot open include file: 'cairo.h'</code>.</p>
<p>I have read everything that I found on this carefully. If you can suggest any help, please do it.</p>

Download a image from server to android and show in imageview
|
<p>I have an server (i use GlassFish). I am able to send Json or XML etc. with http to my android device. I saw an example to upload a picture from my android device to the server. That converts my picked image to byte, converts to String and back at my server. So i can put it on my PC (server).
Now i just want the opposite: get a picture from my PC and with the URL get the image (bitmap here) to imageview. but with debugging bmp seems to be "null". google says its because my image is not a valid bitmap (so maybe something is wrong at my server encoding?).
What does i need to change to this code to get it working?</p>
<p>Server code:</p>
<pre><code>public class getImage{
String imageDataString = null;
@GET
@Path("imageid/{id}")
public String findImageById(@PathParam("id") Integer id) {
//todo: schrijf een query voor het juiste pad te krijgen!
System.out.println("in findImageById");
File file = new File("C:\\Users\\vulst\\Desktop\\MatchIDImages\\Results\\R\\Tensile_Hole_2177N.tif_r.bmp");
try{
// Reading a Image file from file system
FileInputStream imageInFile = new FileInputStream(file);
byte imageData[] = new byte[(int) file.length()];
imageInFile.read(imageData);
// Converting Image byte array into Base64 String
imageDataString = Base64.encodeBase64URLSafeString(imageData);
imageInFile.close();
System.out.println("Image Successfully Manipulated!");
} catch (FileNotFoundException e) {
System.out.println("Image not found" + e);
} catch (IOException ioe) {
System.out.println("Exception while reading the Image " + ioe);
}
return imageDataString;
}
}
</code></pre>
<p>and this is the android side (android studio):</p>
<pre><code>public class XMLTask extends AsyncTask<String, String, String> {
@Override
protected String doInBackground(String... urls) {
HttpURLConnection connection = null;
BufferedReader reader = null;
try {
java.net.URL url = new URL(urls[0]);

<p>The problem is that this algorithm when I have this shape (which is an L shape),</p>
<p>(1,1) (1,10) (2,10) (2,2) (10,2) (10,1) (1,1)</p>
<p>It gives me the result (3.62, 3.62). Which is OK, except that point is outside the shape. Is there another algorithm around that takes this into account?</p>
<p>Basically a person is going to be drawing a shape on a map. This shape might span multiple roads (so could be an L shape) and I want to work out the centre of the shape. This is so I can work out the road name at that point. It doesn't make sense to me for it to be outside the shape if they have drawn a long skinny L shape.</p>

Can't deploy app to ios 8 device
|
<p>Just updated an iPad Mini to iOS 8 and suddenly can't debug my app on it with XCode 6.0.1.
The error in Xcode is <code>App installation failed</code> with <code>An unknown error has occurred.</code>. On the device the app remains greyed out.</p>
<p>Tried to :</p>
<ul>
<li>delete the app from ipad ( was working before )</li>
<li>Soft reset and reboot the device </li>
<li>Delete derived data and clean</li>
<li>Reboot the mac </li>
<li>reinstall xcode</li>
<li>change the bundle id and product name</li>
<li>Recreate the dev certificates and provisioning profiles</li>
</ul>
<p>With iOS 6 and iOS 7 devices works fine, also, can debug other projects too, but not this one, so I'm getting desperate. </p>
<p>Any idea ? </p>

<p>It seems that the regeneration of the certificates was the solution but after Clean there was necessary a Clean Build Folder too, which solved the issue (for now at least).</p>

Generate the JPA metamodel files using maven-processor-plugin - What is a convenient way for re-generation?
|
<p>I am trying to use maven-processor-plugin for generating JPA metamodel java files and I set up my pom.xml as belows. </p>
<pre><code><plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
<compilerArgument>-proc:none</compilerArgument>
</configuration>
</plugin>
<plugin>
<groupId>org.bsc.maven</groupId>
<artifactId>maven-processor-plugin</artifactId>
<executions>
<execution>
<id>process</id>
<goals>
<goal>process</goal>
</goals>
<phase>generate-sources</phase>
<configuration>
<!-- source output directory -->
<outputDirectory>${basedir}/src/main/java</outputDirectory>
<processors>
<processor>org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor</processor>
</processors>
<overwrite>true</overwrite>
</configuration>
</execution>
</executions>
</plugin>
</code></pre>
<p>Actually, I want to generate metamodel files (Entity_.java) to the same packages of their corresponding entities (Entity.java). Hence, I set up outputDirectory in the plugin as </p>
<pre><code><outputDirectory>${basedir}/src/main/java</outputDirectory>
</code></pre>
<p>The first time of running is ok, but from later times when performing the metamodel java files re-generation, the plugin always turns out an error about file duplication.</p>
<p>My Question is
- Is there any way to config the plugin so that it could overwrite the existing files during re-generation?</p>
<p>In fact, to work around</p>
<ol>
<li>I must delete all generated files before any re-generation.</li>
<li>I could point the outputDirectory to a different folder in /target, this location will be clean everytime Maven run, but this
leads to manually copy generated metamodel files to source folder
for update after re-generation.</li>
</ol>
<p>Both of these are very inconvenient and I hope you guys could show me a proper solution.</p>

What's the net::ERR_HTTP2_PROTOCOL_ERROR about?
|
<p>I'm currently working on a website, which triggers a <code>net::ERR_HTTP2_PROTOCOL_ERROR 200</code> error on Google Chrome. I'm not sure exactly what can provoke this error, I just noticed it pops out only when accessing the website in HTTPS. I can't be 100% sure it is related, but it looks like it prevents JavaScript to be executed properly.</p>
<p>For instance, the following scenario happens :</p>
<ol>
<li><p>I'm accessing the website in HTTPS</p>
</li>
<li><p>My Twitter feed integrated via <a href="https://publish.twitter.com" rel="noreferrer">https://publish.twitter.com</a> isn't loaded at all</p>
</li>
<li><p>I can notice in the console the ERR_HTTP2_PROTOCOL_ERROR</p>
</li>
<li><p>If I remove the code to load the Twitter feed, the error remains</p>
</li>
<li><p>If I access the website in HTTP, the Twitter feed appears and the error disappears</p>
</li>
</ol>
<p>Google Chrome is the only web browser triggering the error: it works well on both Edge and Firefox.
(NB: I tried with Safari, and I have a similar <code>kcferrordomaincfnetwork 303</code> error)</p>
<p>I was wondering if it could be related to the header returned by the server since there is this '200' mention in the error, and a 404 / 500 page isn't triggering anything.</p>
<p>Thing is the error isn't documented at all. Google search gives me very few results. Moreover, I noticed it appears on very recent Google Chrome releases; the error doesn't pop on v.64.X, but it does on v.75+ (regardless of the OS; I'm working on Mac tho).</p>
<hr />
<p>Might be related to <a href="https://stackoverflow.com/questions/49927327/website-ok-on-firefox-but-not-on-safari-kcferrordomaincfnetwork-error-303-neit">Website OK on Firefox but not on Safari (kCFErrorDomainCFNetwork error 303) neither Chrome (net::ERR_SPDY_PROTOCOL_ERROR)</a></p>
<hr />
<p>Findings from further investigations are the following:</p>
<ul>
<li><strong>error doesn't pop on the exact same page if server returns 404 instead of 2XX</strong></li>
<li>error doesn't pop on local with a HTTPS certificate</li>
<li>error pops on a different server (both are OVH's), which uses a different certificate</li>
<li>error pops no matter what PHP version is used, from 5.6 to 7.3 (framework used : Cakephp 2.10)</li>
</ul>
<p>As requested, below is the returned header for the failing ressource, which is the whole web page. Even if the error is triggering on each page having a HTTP header 200, those pages are always loading on client's browser, but sometimes an element is missing (in my exemple, the external Twitter feed). Every other asset on the Network tab has a success return, except the whole document itself.

<p>A <code>curl --head --http2</code> request in console returns the following success:</p>

</code></pre>
<hr />
<p>Trying to go deeper with the chrome://net-export/ and <a href="https://netlog-viewer.appspot.com" rel="noreferrer">https://netlog-viewer.appspot.com</a> tools is telling me the request ends with a RST_STREAM :</p>
<pre><code>t=123354 [st=5170] HTTP2_SESSION_RECV_RST_STREAM
--> error_code = "2 (INTERNAL_ERROR)"
--> stream_id = 1
</code></pre>
<p>For what I read in <a href="https://stackoverflow.com/questions/28736463/rst-stream-frame-in-http2">this other post</a>, "<em>In HTTP/2, if the client wants to abort the request, it sends a RST_STREAM. When the server receives a RST_STREAM, it will stop sending DATA frames to the client, thereby stopping the response (or the download). The connection is still usable for other requests, and requests/responses that were concurrent with the one that has been aborted may continue to progress.
[...]
It is possible that by the time the RST_STREAM travels from the client to the server, the whole content of the request is in transit and will arrive to the client, which will discard it. However, for large response contents, sending a RST_STREAM may have a good chance to arrive to the server before the whole response content is sent, and therefore will save bandwidth.</em>"</p>
<p>The described behavior is the same as the one I can observe. But that would mean the browser is the culprit, and then I wouldn't understand why it happens on two identical pages with one having a 200 header and the other a 404 (same goes if I disable JS).</p>

Reactjs Bootstrap Overriding CSS

<p>I am learning react and nextjs, and am faced with a problem where the bootstrap css is overriding my own css.

Why does Celery work in Python shell, but not in my Django views? (import problem)
|
<p>I installed Celery (latest stable version.)
I have a directory called <code>/home/myuser/fable/jobs</code>. Inside this directory, I have a file called tasks.py:</p>
<pre><code>from celery.decorators import task
from celery.task import Task
class Submitter(Task):
def run(self, post, **kwargs):
return "Yes, it works!!!!!!"
</code></pre>
<p>Inside this directory, I also have a file called celeryconfig.py:</p>
<pre><code>BROKER_HOST = "localhost"
BROKER_PORT = 5672
BROKER_USER = "abc"
BROKER_PASSWORD = "xyz"
BROKER_VHOST = "fablemq"
CELERY_RESULT_BACKEND = "amqp"
CELERY_IMPORTS = ("tasks", )
</code></pre>
<p>In my <code>/etc/profile</code>, I have these set as my PYTHONPATH:</p>
<ul>
<li><code>PYTHONPATH=/home/myuser/fable:/home/myuser/fable/jobs</code></li>
</ul>
<p>So I run my Celery worker using the console (<code>$ celeryd --loglevel=INFO</code>), and I try it out.
I open the Python console and import the tasks. Then, I run the Submitter.</p>
<pre><code>>>> import fable.jobs.tasks as tasks
>>> s = tasks.Submitter()
>>> s.delay("abc")
<AsyncResult: d70d9732-fb07-4cca-82be-d7912124a987>
</code></pre>
<p>Everything works, as you can see in my console</p>
<pre><code>[2011-01-09 17:30:05,766: INFO/MainProcess] Task tasks.Submitter[d70d9732-fb07-4cca-82be-d7912124a987] succeeded in 0.0398268699646s:
</code></pre>
<p>But when I go into my Django's views.py and run the exact 3 lines of code as above, I get this:</p>
<pre><code>[2011-01-09 17:25:20,298: ERROR/MainProcess] Unknown task ignored: "Task of kind 'fable.jobs.tasks.Submitter' is not registered, please make sure it's imported.": {'retries': 0, 'task': 'fable.jobs.tasks.Submitter', 'args': ('abc',), 'expires': None, 'eta': None, 'kwargs': {}, 'id': 'eb5c65b4-f352-45c6-96f1-05d3a5329d53'}

<p>It's weird, because the celeryd client does show that it's registered, when I launch it.</p>

ASP.Net: How to maintain TextBox State after postback
|
<p>I would like to know how to maintain the control state that has been modified in Javascript.<br />
I have two TextBoxes, one DropDownList and a button (all Runat=Server) in C# ASP.net 2010 Express.<br /><br />
First textbox is just accept whatever data user input. <br />Second textbox enable state will change based on DDL selected value. <br />If ddl selected value is "-", second textbox will become Enabled = False. <br />
If not "-", it will become Enabled = True. This enable is done through Javascript.</p>
<p><br />
In my Page Load event, I have below code.</p>
<pre><code>if (!IsPostBack)
{
txtKey2.Text = "";
txtKey2.BackColor = System.Drawing.ColorTranslator.FromHtml("#CCCCCC");
txtKey2.Enabled = false;
}
</code></pre>
<p><br />And in my aspx page, I have some javascript which will clear the textbox data and disable the textbox.</p>
<p>Here is for Second Textbox.</p>
<pre><code><asp:TextBox ID="txtKey2" runat="server" Width="425px" EnableViewState="False"></asp:TextBox>
</code></pre>
<p><br />
And here is for DDL.</p>
<pre><code><asp:DropDownList ID="selKey1" runat="server" onchange="EnableSelkey(this.value,1)">
<asp:ListItem Value="0">-</asp:ListItem>
<asp:ListItem Value="1">AND</asp:ListItem>
<asp:ListItem Value="2">OR</asp:ListItem>
</asp:DropDownList>
</code></pre>
<p>Here is the code for my Javascript. (I have a plan to implement other textbox and ddl so in my code I have Else if condition).</p>
<pre><code>function EnableSelkey(val, strID) {
var txtBox;
if (strID == "1")
txtBox = document.getElementById('<%= txtKey2.ClientID %>');
else if (strID == "2")
txtBox = document.getElementById('<%= txtKey3.ClientID %>');
else
txtBox = document.getElementById('<%= txtKey4.ClientID %>');
if (val != 0) {
txtBox.disabled = false;
txtBox.style.backgroundColor = "White";
txtBox.value = "";
txtBox.select();
}
else {
txtBox.disabled = true;
txtBox.style.backgroundColor = "#CCCCCC";
txtBox.value = "";
}
}
</code></pre>
<p>I have nothing in button click event.</p>
<p>By using above all code, when I run the project, the page loads Ok.
The second textbox enabled state is set to False (through Page_Load event). So far Ok.</p>
<p>Then from my browser, I choose ddl value to other instead of "-", the textbox become enable because of javascript. This is Ok.</p>
<p>I input the value and click on the button. Page PostBack happens here. Textbox is still enabled (because of EnableViewState = False for my textbox).</p>
<p>I choose ddl value to "-", second textbox became disabled.
<br />Click on the button, page postback happen, but this time the textbox is still enabled. << This is the issue I'm trying to solve. I change EnableViewState, ViewStateMode in different values but still the same.</p>
<p>Is there any solution for this one?</p>
<p>Here is my test image URL.
<a href="http://postimg.org/image/atrtkip49/" rel="nofollow">State 1</a> ,
<a href="http://postimg.org/image/3pa0bhhux/" rel="nofollow">State 2</a> ,
<a href="http://postimg.org/image/hy9mtjwdl/" rel="nofollow">State 3</a> <br /></p>
<p>Sorry for the long post.</p>

OnCheckedChanged event not firing
|
<p>I have a GridView with a column of checkboxes (the rest of the GridView is being populated from a database). I'm using AJAX to perform different functions, and I'm wondering if i'm just not calling the OnCheckedChanged event in the right place. Should it be wrapped in some sort of UpdatePanel? I'm still really new to how all of this works...basically what I'm aiming for is to change a bit value in my database when a checkbox is checked. I know the logic of how to do that, I just don't know if I'm addressing my OnCheckedChanged event the right way.</p>

Why is ASP.NET throwing so many exceptions?
|
<p>By coincidence I watched the debug output of Visual Studio a bit. I can see hundreds and hundreds of various exceptions being thrown. I checked another ASP.NET based solution and it is showing same behavior. Why are all those exceptions thrown? I cannot believe it is good for the overall performance, is it?
Look at the excerpt below. It is the output of appr. 30 seconds surfing. Most are HttpExceptions but there are also FormatExceptions and ArgumentOutOfRangeExceptions. None of these is really affecting the usage. Nothing crashes. Does anybody have an explanation, as it seems to be "normal"?</p>

How get <body> element from the html which one have as a string
|
<p>I have a stupid problem. An <code>jQuery.ajax</code> request return me a <strong>full HTML text</strong> as a string. I receive such response in an case of error on the server. The server give me an error description which I want to place inside of the corresponding place of my current page.</p>
<p>So now the question: I have a string contains full HTML document (which is not an XML!!! see <code><hr></code> element inside). I need to have for example only BODY part as a jQuery object. Then I could append it to the corresponding part of my page.</p>
<p>Here is an example of the string which I need to parse:</p>
<pre><code><html>
<head>
<title>The resource cannot be found.</title>
<style>
body {font-family:"Verdana";font-weight:normal;font-size: .7em;color:black;}
p {font-family:"Verdana";font-weight:normal;color:black;margin-top: -5px}
// ...
</style>
</head>
<body bgcolor="white">

Bcrypt installation fails in Docker
|
<p>I've created a Node-application with MongoDB that runs in Docker. It worked fine until I included <a href="https://github.com/ncb000gt/node.bcrypt.js" rel="nofollow">node.bcrypt.js</a>. This makes Node crash with <code>node-gyp</code> and <code>bcrypt</code>.</p>
<p>The app runs fine locally and on Heroku.</p>
<p>I tried to install a few suggested packages that I found online, that were known to be needed based on error messages. This is why I've added a few extra dependencies, see the <code>node-gyp</code>-related line in the dockerfile below. </p>
<p>Now it's gotten where I cannot find any more suggestions, but it still doens't work. I feel it's weird that it works both locally and on Heorku, but not on Docker, and therefore that it's something I'm missing.</p>
<p>Thanks in advance.</p>
<p>Error:</p>

<p>This is after I added a few installations to my Dockerfile, see the line after <code>node-gyp</code>. Dockerfile:</p>
<pre><code># Base Docker-image on Ubuntu
FROM ubuntu:latest
#install mongodb
#install git, curl, python and mongo
# node-gyp
RUN apt-get install -y build-essential make automake gcc g++ cpp libkrb5-dev libc6-dev man-db autoconf pkg-config
# Create the MongoDB data directory
RUN mkdir -p /data/db
# mongodb setup
# Install NodeJS
RUN curl --silent --location https://deb.nodesource.com/setup_0.12 | sudo bash -
RUN apt-get update && apt-get install -y nodejs
RUN npm install -g node-gyp
# Git-clone project
# expose ports
# Install dependencies and start server and database
CMD cd /server && sh start.sh
</code></pre>
<p>The <code>starth.sh</code>-script simply installs dependencies and starts both MongoDB and server.</p>
<p><strong>EDIT:</strong>
The <a href="https://github.com/ncb000gt/node.bcrypt.js" rel="nofollow">repo</a> tells me to check out the <a href="https://github.com/nodejs/node-gyp" rel="nofollow">node-gyp dependencies</a>, but I feel that's been covered by the Dockerfile shown above.</p>

<p>Please help. I have already tried removing router links from my template.</p>

Silverlight Listbox Item Style
|
<p>How would one go about styling a listbox such that the selection has a different text color than the default view? I've looked at this in several ways and because the ContentPresenter lacks a Foreground property. </p>
<p>The default control template of the listbox provides several rectangles which one can use to adjust the highlight color. For example, with the default style a rectangle called BGColor3 has its opacity adjusted to get a highlight effect.</p>
<p>Here is the bulk of my control template: </p>
<pre><code><Grid>
<Rectangle x:Name="BGColor2" Fill="{StaticResource HoverBrush}" Stroke="Black" StrokeThickness="1" Opacity="0"/>
<Rectangle x:Name="BGColor3" Fill="{StaticResource ListboxHighlightBrush}" StrokeThickness="0" Opacity="0"/>
<Rectangle x:Name="BGColor" Stroke="Black" StrokeThickness="0" Opacity="0.2" Fill="{TemplateBinding Background}"/>
<Border Height="20">
<ContentPresenter HorizontalAlignment="Left" Margin="{TemplateBinding Padding}" x:Name="contentPresenter" Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}"/>
</Border>
<Rectangle Fill="Blue" Opacity="0.4" x:Name="FocusVisual" Stroke="#BF313131" Margin="1" StrokeThickness="1" StrokeDashArray="1 2" StrokeDashCap="Square" Visibility="Collapsed" />
<Rectangle x:Name="BorderRect" Stroke="Black" StrokeThickness="1" Opacity="0.3" />
</Grid>
</code></pre>
<p>In the selection Visual State, here is the gist:</p>
<pre><code><VisualStateGroup x:Name="SelectionStates">
<VisualState x:Name="Unselected"/>
<VisualState x:Name="Selected">
<Storyboard>
<DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Duration="00:00:00.0010000" Storyboard.TargetName="BGColor2" Storyboard.TargetProperty="(UIElement.Opacity)">
<SplineDoubleKeyFrame KeyTime="00:00:00" Value="0.8"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
</VisualStateGroup>
</code></pre>
<p>What is evident is that BGColor2 the rectangle is being modified (opacity) so that the selected item has a background. Fair enough. Within this portion of the Storyboard, is there anyway to access either the ContentPresenter or something else similar and toggling the text foreground color?</p>
<p>Footnote: wouldn't it be much cleaner to simply have different templates versus visual state transitions?</p>
<p>---- added after first answer given ----</p>
<p>Using a TextBlock <em>almost</em> does the trick but what's interesting is that the transition for SelectedUnfocused does not appear to be enforced which is to say that implementing your solution works perfectly until a person mouses over a previously selected item then the text once again goes to black. </p>
<p>Here is my template:</p>
<pre><code><!-- ItemStyle brushes -->
<SolidColorBrush x:Key="BaseColorBrush" Color="White"/>
<SolidColorBrush x:Key="BaseColorBrushFaint" Color="#265B0000"/>

Having a div/0 error in excel 2007 return a 0 with in a large formula
|
<p>I apologize if this is not considered real programming since it is in Excel but I need help and this is the most helpful place I know!</p>
<p>Alright so I have a very large if formula in excel:</p>
<pre><code>=IF(AND(($EZ16+LF$1139)>$B$1145,($EZ16+LF$1139)<$B$1146),IF(OR(AND($FB16<LF$1141,$FB16>LF$1142),AND($FE16<LF$1141,$FE16>LF$1142),AND($FH16<LF$1141,$FH16>LF$1142),AND($FK16<LF$1141,$FK16>LF$1142),AND($FN16<LF$1141,$FN16>LF$1142),AND($FQ16<LF$1141,$FQ16>LF$1142),AND($FT16<LF$1141,$FT16>LF$1142),AND($FW16<LF$1141,$FW16>LF$1142),AND($FZ16<LF$1141,$FZ16>LF$1142),AND($GC16<LF$1141,$GC16>LF$1142),AND($GF16<LF$1141,$GF16>LF$1142)),FALSE,(EU16/EI16-1)),FALSE)
</code></pre>
<p>What can I do to it so that if it returns a div/0 error it will pass a value of 0 instead of the <code>#DIV/0!</code> error?</p>
<p>Would it be something like:</p>
<pre><code>=IF(ISERROR(A1/B1),0,A1/B1)
</code></pre>
<p>If so how can I add that to my current formula and not break it? Would it be:</p>
<pre><code>=IF(ISERROR(IF(AND(($EZ16+LF$1139)>$B$1145,($EZ16+LF$1139)<$B$1146),IF(OR(AND($FB16<LF$1141,$FB16>LF$1142),AND($FE16<LF$1141,$FE16>LF$1142),AND($FH16<LF$1141,$FH16>LF$1142),AND($FK16<LF$1141,$FK16>LF$1142),AND($FN16<LF$1141,$FN16>LF$1142),AND($FQ16<LF$1141,$FQ16>LF$1142),AND($FT16<LF$1141,$FT16>LF$1142),AND($FW16<LF$1141,$FW16>LF$1142),AND($FZ16<LF$1141,$FZ16>LF$1142),AND($GC16<LF$1141,$GC16>LF$1142),AND($GF16<LF$1141,$GF16>LF$1142)),FALSE,(EU16/EI16-1)),FALSE))**),0,IF**(AND(($EZ16+LF$1139)>$B$1145,($EZ16+LF$1139)<$B$1146),IF(OR(AND($FB16<LF$1141,$FB16>LF$1142),AND($FE16<LF$1141,$FE16>LF$1142),AND($FH16<LF$1141,$FH16>LF$1142),AND($FK16<LF$1141,$FK16>LF$1142),AND($FN16<LF$1141,$FN16>LF$1142),AND($FQ16<LF$1141,$FQ16>LF$1142),AND($FT16<LF$1141,$FT16>LF$1142),AND($FW16<LF$1141,$FW16>LF$1142),AND($FZ16<LF$1141,$FZ16>LF$1142),AND($GC16<LF$1141,$GC16>LF$1142),AND($GF16<LF$1141,$GF16>LF$1142)),FALSE,(EU16/EI16-1)),FALSE))

<p>Thank you for the help!</p>

<p>Unfortunately, I can't figure out how to avoid this error.</p>
<p>I found a few other StackOverflow posts. <a href="https://stackoverflow.com/questions/30448687/pycharm-valueerror-failed-to-parse-cpython-sys-version">This one</a> suggests reinstalling python and pycharm from scratch (but I just installed Anaconda and I don't use pycharm). <a href="https://stackoverflow.com/questions/31304636/installing-modules-with-pip-failed-to-parse-cpython-sys-version">Another suggests</a> reinstalling canopy, but I'm not using that here. Finally, <a href="https://stackoverflow.com/questions/19105255/praw-failed-to-parse-cpython-sys-version-when-creating-reddit-object">a third suggests</a> that it's actually a bug, and proposes a fix. Unfortunately, re-naming <code>sys.version</code> fails to resolve the error. This isn't even my computer so I don't want to get deep into the code and risk messing something up.</p>
<p>I would appreciate some thoughts or advice.</p>

Yii and .htaccess file on production server
|
<p>I am new to yii and have some problem in configuring .htaccess file on production server.</p>
<p><strong>On localhost :</strong> </p>
<p><strong>Location of Application :</strong> /www/connect_donors/</p>
<p><strong>Default URL that yii provides is</strong>,</p>
<pre><code>http://localhost/connect_donors/index.php?r=controllerId/functionName
</code></pre>
<p>We used the urlManager in /connect_donors/protected/config/main.php to configure the SEO friendly url's..</p>
<pre><code>'<controller:\w+>/<id:\d+>' => '<controller>/view',
'<controller:\w+>/<action:\w+>/<id:\d+>' => '<controller>/<action>',
'<controller:\w+>/<action:\w+>' => '<controller>/<action>'
</code></pre>
<p>Now the URL that was working was</p>
<pre><code>http://localhost/connect_donors/index.php/controllerId/functionName
</code></pre>
<p>Then I used the .htaccess file to remove index.php from the above URL.</p>
<p>Location of .htaccess is : /connect_donors/.htaccess</p>
<p>Following is .htaccess file,</p>
<pre><code>RewriteEngine On
RewriteBase /connect_donors
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)\?*$ index.php/$1 [L,QSA]
</code></pre>
<p><strong>URL Chenged to :</strong> </p>
<pre><code>http://localhost/connect_donors/controllerId/functionName
</code></pre>
<p>Everything working fine and awesome.</p>
<p>But yesterday I uploaded the application on production server.</p>
<p><strong>On Production Server</strong></p>
<p>Everything remained same only I had to change the .htaccess file.</p>
<p>The .htaccess file on server is,</p>
<pre><code>RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)\?*$ index.php/$1 [L,QSA]
</code></pre>
<p>Now the following url:</p>
<pre><code>http://donorsconnect.com/
</code></pre>
<p>loads the home page of server properly.</p>
<p>But,
<a href="http://donorsconnect.com/profile" rel="nofollow">http://donorsconnect.com/profile</a> </p>
<p>redirects again to home page.</p>
<p>NOTE : There is no session set on the "profile" controller.</p>
<pre><code>class ProfileController extends CController
{
public function actionIndex()
{
$this->render('index');
}
}
</code></pre>
<p>I tried lot of things, changing the .htaccess file to different codes. but none helped me.</p>
<p>Any help is appreciable.</p>
<p><strong>Solution</strong></p>
<p>I finally got the solution and the mistake I had done.</p>
<p>My Components had a request array containing baseUrl.</p>
<pre><code>'components'=>array(
...
'request' => array(
'baseUrl' => 'http://donorsconnect.com',
...),
</code></pre>
<p>Due to this it was not loading. I did not find the real reason for that.</p>
<p>But after removing that 'request' array, its loading fine.</p>

How can I disable code signing for debug builds in Visual Studio 2013?
|
<p>We recently upgraded Visual Studio from 2010 to 2013 and everything seems to be working the same as before except for one thing. In 2010 code signing was only performed when publishing the project, but in 2013 it wants to sign the output assembly every time we build the project.</p>
<p>I'm having issues trying to find any results online about this, everything only points to how to setup signing in the first place, not how to prevent it signing during normal debug builds.</p>
<hr>
<p>I created a new project and started playing with the settings to determine what single setting may be triggering the signing requirement during normal builds. In the project properties page under the Security tab, if the "Enable ClickOnce security settings" check box is checked then 2013 requires the signing step but 2010 doesn't seem to have that requirement.</p>
<p>I still need to confirm whether or not this is the single decision point for this behavior.</p>
<hr>
<p>Confirmed.</p>
<p>I created two solutions each with a single empty WinForms application. One solution was created in Visual Studio 2010 and the other was created in Visual Studio 2013. I went into the project properties on each and enabled signing via the signing tab and then checked the "Enable ClickOnce security settings" in the security tab with "This is a full trust application". Note that the projects are being signed with a certificate on a smart-card which is PIN enabled.</p>
<p>VS 2013 prompts for the smart card PIN during a normal build in debug mode, 2010 does not. Now the question is basically why there is a difference between the two versions and how to fix this in 2013 to behave like 2010.</p>
<hr>
<p>I'm including the project files for the test solutions I created below. Comparing the differences doesn't point to anything obviously different. I also attempted to change the VS 2013 project to target the same framework as the VS 2010 project to minimize the differences between the projects - this doesn't change the behavior difference.</p>

Scikit-learn - ValueError: Input contains NaN, infinity or a value too large for dtype('float32') with Random Forest
|
<p>First, I have checked the different posts concerning this error and none of them can solve my issue.</p>
<p>So I am using RandomForest and I am able to generate the forest and to do a prediction but sometimes during the generation of the forest, I get the following error.</p>
<blockquote>
<p>ValueError: Input contains NaN, infinity or a value too large for dtype('float32').</p>
</blockquote>
<p>This error occurs with the same dataset. Sometimes the dataset creates an error during the training and most of the time not. The error sometimes occurs at the start and sometimes in the middle of the training.</p>
<p>Here's my code :</p>
<pre><code>import pandas as pd
from sklearn import ensemble
import numpy as np

# Execution logic goes here
Input = dataframe1.values[:,:]
InputData = Input[:,:15]

limitTrain = 2175
clf = ensemble.RandomForestClassifier(n_estimators = 10000, n_jobs = 4 );
features=np.empty([len(InputData),10])
j=0
for i in range (0,14):

features[:,j] = (InputData[:, i])
j += 1
clf.fit(features[:limitTrain,:],np.asarray(InputTarget[:limitTrain,1],dtype = np.float32))

listreu[i,4] = 0;
elif(res[i,1] > 0.5):
listreu[i,4] = 1;
elif(res[i,2] > 0.5):
listreu[i,4] = 2;
else:
listreu[i,4] = 3;

listreu[:,1] = InputData[limitTrain+1:,2]
listreu[:,2] = InputData[limitTrain+1:,3]
listreu[:,3] = features[limitTrain+1:,1]
# Return value must be of a sequence of pandas.DataFrame
return pd.DataFrame(listreu),
</code></pre>
<p>I ran my code locally and on <code>Azure ML</code> Studio and the error occurs in both cases.</p>
<p>I am sure that it is not due to my dataset since most of the time I don't get the error and I am generating the dataset myself from different input.</p>
<p>This is a <a href="http://%20https://pastebin.com/mC76uq8P" rel="nofollow noreferrer">part of the dataset I use</a></p>
<p><strong>EDIT:</strong> I probably found out that I had 0 value which were not real 0 value. The values were like</p>

Selecting a subset of a Pandas DataFrame indexed by DatetimeIndex with a list of TimeStamps
|
<p>I have a large Pandas <code>DataFrame</code></p>
<pre><code><class 'pandas.core.frame.DataFrame'>
DatetimeIndex: 3425100 entries, 2011-12-01 00:00:00 to 2011-12-31 23:59:59
Data columns:
sig_qual 3425100 non-null values
heave 3425100 non-null values
north 3425099 non-null values
west 3425097 non-null values
dtypes: float64(4)
</code></pre>
<p>I select a subset of that <code>DataFrame</code> using <code>.ix[start_datetime:end_datetime]</code> and I pass this to a <a href="https://gist.github.com/1178136" rel="nofollow noreferrer">peakdetect function</a> which returns the index and value of the local maxima and minima in two seperate lists. I extract the index position of the maxima and using <code>DataFrame.index</code> I get a list of pandas TimeStamps.</p>
<p>I then attempt to extract the relevant subset of the large DataFrame by passing the list of TimeStamps to <code>.ix[]</code> but it always seems to return an empty <code>DataFrame</code>. I can loop over the list of TimeStamps and get the relevant rows from the <code>DataFrame</code> but this is a lengthy process and I thought that <code>ix[]</code> should accept a list of values according to <a href="http://pandas.sourceforge.net/indexing.html" rel="nofollow noreferrer">the docs</a>?
<em>(Although I see that the example for Pandas 0.7 uses a <code>numpy.ndarray</code> of <code>numpy.datetime64</code>)</em></p>
<p><strong>Update:</strong>
A small 8 second subset of the DataFrame is selected below, # lines show some of the values:</p>
<pre><code>y = raw_disp['heave'].ix[datetime(2011,12,30,0,0,0):datetime(2011,12,30,0,0,8)]
#csv representation of y time-series

</code></pre>
<p><strong>Update 2:</strong>
I <a href="https://gist.github.com/3377772" rel="nofollow noreferrer">created a gist</a>, which actually works because when the data is loaded in from csv the index columns of timestamps are stored as numpy array of objects which appear to be strings. Unlike in my own code where the index is of type <code><class 'pandas.tseries.index.DatetimeIndex'></code> and each element is of type <code><class 'pandas.lib.Timestamp'></code>, I thought passing a list of <code>pandas.lib.Timestamp</code> would work the same as passing individual timestamps, would this be considered a bug?</p>
<p>If I create the original <code>DataFrame</code> with the index as a list of strings, querying with a list of strings works fine. It does increase the byte size of the DataFrame significantly though.</p>
<p><strong>Update 3:</strong>
The error only appears to occur with very large DataFrames, I reran the code on varying sizes of DataFrame ( some detail in a comment below ) and it appears to occur on a DataFrame above 2.7 million records. Using strings as opposed to TimeStamps resolves the issue but increases memory usage.</p>
<p><strong>Fixed</strong>
In latest github master (18/09/2012), see comment from Wes at bottom of page.</p>

How to Add Columns to Jquery DataTable Dynamically
|
<p>I have a student Fee module, and I want to Generate Fee Class wise. Means Generate Fee for a whole Class, not for a Specific Student. <code>DataTable</code> will look like below..</p>
<pre><code>|RegistrationNo | Name | AdmissionFee | TutionFee | SportsFee | Exam Fee| Discount |
------------------------------------------------------------------------------------
| 50020 | A | 1000 | 800 | 500 | 400 | 300 |
| 50021 | B | 1000 | 800 | 500 | 400 | 100 |
</code></pre>
<p>so on, whole class...</p>
<p>The problem is that the <code>Fees</code> are defined by school, so i have not a fix number of fees, e.g <code>Transport Fee</code> can be defined, <code>Library Fee</code> can be defined and any other fee that school wants can define. so these Fee Names come from a <code>FeeDefination</code> Table. Now how i should add these Fees to <code>aoColumns</code> as attribute.
I have try the below code...</p>
<pre><code> var html = '[';
var oTable = $('#GenerateFeeDataTable').dataTable({
"bJQueryUI": true,
"bServerSide": true,
"bPaginate": false,
"bFilter": false,
"bInfo": false,
"sAjaxSource": "/forms/StudentFee/studentfee.aspx/GenerateStudentFee?CampusId=" + campusId + "&ClassId= " + classId + '&Session=' + JSON.stringify(session) + "&FeeModeId=" + feeModeId,
"fnServerData": function (sSource, aoData, fnCallback) {
$.ajax({
"type": "GET",
"dataType": 'json',
"contentType": "application/json; charset=utf-8",
"url": sSource,
"data": aoData,
"success": function (data) {
var data = data.d;
html += '{"sTitle":"Registration No","mDataProp":"RegistrationNo","bSearchable":false,"bSortable":false},';
html += '{"sTitle":"Student Name","mDataProp":"StudentName","bSearchable":false,"bSortable":false},';
html = html.substring(0, html.length - 1);
html += ']';
fnCallback(data);
}
});
},
"aoColumns": html
});
</code></pre>
<p>How ever i have taken <code>aoColumns</code> attributes static in <code>fnServerData</code>, but these will not be fixed, i am just trying that i will work or not, but its not working..</p>
<pre><code>My Questions are :
1) How to handle this situation, means how to add aoColumns dynamically.
2) How to get Header/Variables Name from JSON aaData, below is the Image to understand.
</code></pre>
<p><img src="https://i.stack.imgur.com/pEdQl.png" alt="enter image description here"></p>
<p>Is there any way to do such task, Any Help..</p>

Save CSV files into mysql database
|
<p>I have a lot of csv files in a directory. With these files, I have to write a script that put their content in the right fields and tables of my database. I am almost beginner in php language : I have found some bits of code on the Internet. It seems to work, but I am stuck at a stage. Some topics are related on this website, but I did not found the ecat problem.</p>
<p>I have written a php script that permits to get the path and the name of these files. I managed too to create a table whose name depends of each csv (e.g : file ‘data_1.csv’ gives the table data_1.csv in my-sql). All the tables have the three same fields, id, url, value.
The last thing to do is to populate these tables, by reading each file and put the values separated by ‘|’ character in the right tables. For example, if a line of ‘data_1.csv’ is</p>
<p>8756|htttp://example.com|something written</p>
<p>I would like to get a record in data_1.csv table where 8756 is in id, htttp://example.com in url field, and something written in value field.
I have found the way to read and print these csv with fcsvget function. But I do not know how to make these lines go into the SQL database. Could anyone help me on this point?</p>
<p>Here is my script below</p>
<pre><code><?php

Find the index of the n'th item in a list
|
<p>I want to find the index of the n'th occurrence of an item in a list. e.g., </p>
<pre><code>x=[False,True,True,False,True,False,True,False,False,False,True,False,True]
</code></pre>
<p>What is the index of the n'th true? If I wanted the fifth occurrence (4th if zero-indexed), the answer is 10.</p>
<p>I've come up with:</p>
<pre><code>indargs = [ i for i,a in enumerate(x) if a ]
indargs[n]
</code></pre>
<p>Note that <code>x.index</code> returns the first occurrence or the first occurrence after some point, and therefore as far as I can tell is not a solution.</p>
<p>There is also a solution in numpy for cases similar to the above, e.g. using <code>cumsum</code> and <code>where</code>, but I'd like to know if there's a numpy-free way to solve the problem.</p>
<p>I'm concerned about performance since I first encountered this while implemented a Sieve of Eratosthenes for a <a href="https://projecteuler.net" rel="noreferrer">Project Euler</a> problem, but this is a more general question that I have encountered in other situations.</p>
<p>EDIT: I've gotten a lot of great answers, so I decided to do some performance tests. Below are <code>timeit</code> execution times in seconds for lists with <code>len</code> nelements searching for the 4000'th/1000'th True. The lists are random True/False. Source code linked below; it's a touch messy. I used short / modified versions of the posters' names to describe the functions except <code>listcomp</code>, which is the simple list comprehension above.</p>

<p>Hettinger's itertools solution is almost always the best. taymon's and graddy's solutions are next best for most situations, though the list comprehension approach can be better for short arrays when you want the n'th instance such that n is high or lists in which there are fewer than n occurrences. If there's a chance that there are fewer than n occurrences, the initial <code>count</code> check saves time. Also, graddy's is more efficient when searching for numbers instead of True/False... not clear why that is. eyquem's solutions are essentially equivalent to others with slightly more or less overhead; eyquem_occur is approximately the same as taymon's solution, while eyquem_occurrence is similar to listcomp.</p>

ERROR: Kendo"Something" is not a function
|
<p>So I am trying to convert my plain HTML/Javascript site (which works fine) into an ASP MVC4 project. What I do is get and XML and use and XSLT to transform. I litreally use the code <a href="https://stackoverflow.com/questions/7471391/using-xslt-in-asp-net-mvc-3">from here</a> to do that </p>
<p>In my <code>_Layout.cshtml</code> I use razor to load the resource</p>
<pre><code><!DOCTYPE html>
<html>
<head>
<title>@ViewBag.Title</title>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
... things...
@Scripts.Render("~/bundles/kendoScripts")
@Scripts.Render("~/bundles/customScript")
@Styles.Render("~/Content/themes/Kendo")
@Styles.Render("~/Content/themes/customCSS")
</code></pre>
<p>my view that uses the layout is very straight forward, this is all that is in the page</p>
<pre><code>@using Summ.ExtensionCode
@model SumMVC.Models.SummaryModel
@{
ViewBag.Title = "_Summary";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<div data-role="content">
@Html.RenderXml(Model.ProgramFilename, Model.StylesheetFilename, Model.Parameters)
</div>
</code></pre>
<p>In <code>@Scripts.Render("~/bundles/customScript")</code>, is a JS file, renderpage.js that has this bit of code <code>$(this).kendoDropDownList();</code> where this is a select element. But I am getting a error that <code>.kendoDropDownList();</code> is not a function. The error from firebug: <code>TypeError: $(...).kendoDropDownList is not a function</code> and the errror from GoogleChrome <code>Uncaught TypeError: Object [object Object] has no method 'kendoDropDownList'</code>. It seems that in my bundle the JS file kendo.all.min.js is not begin loaded here is what is looks like</p>
<pre><code>bundles.Add(new ScriptBundle("~/bundles/kendoScripts")
.Include("~/Scripts/kendoui/kendo.web.min.js")
.Include("~/Scripts/kendoui/kendo.all.min.js")
);
....
bundles.Add(new ScriptBundle("~/bundles/customScript")
.....
.Include("~/Scripts/SummaryScript/renderpage.js")
....
);
</code></pre>
<p>I am assuming that perhaps the code is being executed before kendo.all.min.js is done loading, but as you can see above renderpage.js is after kendo. Any ideas or insight? </p>
<p><strong>UPDATE</strong></p>
<p>I forgot to add that when I manually load the resource in the MVC project in the head tag</p>
<pre><code><script type="text/javascript" src="~/Scripts/kendoui/kendo.web.min.js"></script>
<script type="text/javascript" src="~/Scripts/kendoui/kendo.all.min.js"></script>
....
<script type="text/javascript" src="~/Scripts/ExecSummaryScript/renderpage.js"></script>
</code></pre>
<p>it works fine.</p>
<p><strong>Update2</strong></p>
<p>Turns out the Kendo JS file is not being loaded at all. I check the resource in the dev console and notice that it not even there.Upon closer inspection I notice that all resources are loaded except some <code>.min.js</code> files. There are a few loaded but some that are not loaded are jquery-ui-1.10.3.min.js, and jquery.browser.min.js.</p>

Optimizing the backtracking algorithm solving Sudoku
|
<p>I'm hoping to optimize my backtracking algorithm for my Sudoku Solver.</p>
<hr>
<p>What it does now:</p>
<p>The recursive solver function takes a sudoku puzzle with various given values.</p>
<p>I will scour through all the empty slots in the puzzle, looking for the slot that has the least possibilities, and get the list of values.</p>
<p>From the list of values, I will loop through it by placing one of the values from the list in the slot, and recursively solve it, until the entire grid is filled.</p>
<hr>
<p>This implementation still takes incredibly long for some puzzles and I hope to further optimize this. Does anyone have any ideas how I might be able to further optimize this?</p>
<hr>
<p>Here's my code in Java if you're interested.</p>
<pre class="lang-java prettyprint-override"><code>public int[][] Solve(int[][] slots) {
// recursive solve v2 : optimization revision
int[] least = new int[3];
least[2] = Integer.MAX_VALUE;
PuzzleGenerator value_generator = new PuzzleGenerator();
LinkedList<Integer> least_values = null;
// 1: find a slot with the least possible solutions
// 2: recursively solve.
// 1 - scour through all slots.
int i = 0;
int j = 0;
while (i < 9) {
j = 0;
while (j < 9) {
if (slots[i][j] == 0) {
int[] grid_posi = { i, j };
LinkedList<Integer> possible_values = value_generator
.possibleValuesInGrid(grid_posi, slots);
if ((possible_values.size() < least[2])
&& (possible_values.size() != 0)) {
least[0] = i;
least[1] = j;
least[2] = possible_values.size();
least_values = possible_values;
}
}
j++;
}
i++;
}
// 2 - work on the slot
if (least_values != null) {

ArrayDeepCopy(slots, tempslot);
tempslot[least[0]][least[1]] = x;
/*ConsoleInterface printer = new gameplay.ConsoleInterface();

How to grab values from key:value pairs in parsed JSON in Python
|
<p>I am trying to extract data from a JSON file. Here is my code.</p>
<pre><code>import json
json_file = open('test.json')
data = json.load(json_file)
json_file.close()
</code></pre>
<p>At this point I can print the file using print data and it appears that the file has been read in properly.</p>
<p>Now I would like to grab a value from a key:value pair that is in a dictionary nested within a list nested within a dictionary (Phew!). My initial strategy was to create a dictionary and plop the dictionary nested within the list in it and then extract the key:value pairs I need.</p>
<pre><code>dict = {}
dict = json_file.get('dataObjects', None)
dict[0]
</code></pre>
<p>When I try to look at the contents of dict, I see that there is only one element. The entire dictionary appears to have been read as a list. I've tried a couple of different approaches, but I still wind up with a dictionary read as a list. I would love to grab the nested dictionary and use another .get to grab the values I need. Here is a sample of the JSON I am working with. Specifically, I am trying to pull out the identifier and description values from the dataObjects section.</p>

"description": "Despite its worldwide notoriety, very little is known about the natural ecology and behaviour of this predator. These sharks are usually solitary or occur in pairs, although it is apparently a social animal that can also be found in small aggregations of 10 or more, particularly around a carcass (3) (6). Females are ovoviviparous; the pups hatch from eggs retained within their mother's body, and she then gives birth to live young (10). Great white sharks are particularly slow-growing, late maturing and long-lived, with a small litter size and low reproductive capacity (8). Females do not reproduce until they reach about 4.5 to 5 metres in length, and litter sizes range from two to ten pups (8). The length of gestation is not known but estimated at between 12 and 18 months, and it is likely that these sharks only reproduce every two or three years (8) (11). After birth, there is no maternal care, and despite their large size, survival of young is thought to be low (8).&nbsp;Great whites are at the top of the marine food chain, and these sharks are skilled predators. They feed predominately on fish but will also consume turtles, molluscs, and crustaceans, and are active hunters of small cetaceans such as dolphins and porpoises, and of other marine mammals such as seals and sea lions (12). Using their acute senses of smell, sound location and electroreception, weak and injured prey can be detected from a great distance (7). Efficient swimmers, sharks have a quick turn of speed and will attack rapidly before backing off whilst the prey becomes weakened; they are sometimes seen leaping clear of the water (6). Great whites, unlike most other fish, are able to maintain their body temperature higher than that of the surrounding water using a heat exchange system in their blood vessels (11).",

Angular2- Getting confused with Observable Catch closure scope
|
<p>Wondering if you can give a little assistance. I appear to be getting myself a bit confused when it comes to using <code>catch</code> with <code>Observable</code>s.</p>
<p>Basically what I'm trying to do is the following:
When my API returns a 403 error, I want to perform some actions on my <code>TokenStore</code>, namely, delete the local token and mark the user as unauthenticated. The way I'm trying to do this may be wrong, so please do let me know if there's a better way of accomplishing this.</p>
<p>I'm trying to accomplish this with the following code:</p>
<p><strong>APIConnector.service.ts</strong> - a single service for API communication methods</p>
<pre><code>import {Injectable} from 'angular2/core';
import {Http, Response, Headers, RequestOptions} from 'angular2/http';
import {Observable} from 'rxjs/Observable';
import * as _ from 'lodash';
import {Logger} from './logger.service';
import {TokenStore} from '../stores/token.store';
@Injectable()
export class APIConnector {
private _apiUrl:string = 'https://api.sb.zerojargon.com/';
private _token:string = null;
constructor(
private _http:Http,
private _logger:Logger,
private _tokenStore:TokenStore
) {}
get(endpoint:String, includes:Array<string>) {
let includeString = (!_.isUndefined(includes)) ? this._parseIncludes(includes) : '';
let headers = this._createHeaders();
let options = new RequestOptions({ headers: headers });
return this._http.get(this._apiUrl + endpoint + '?include=' + includeString, options);
}
post(endpoint:String, formData:Object, includes:Array<string>) {
let includeString = (!_.isUndefined(includes)) ? this._parseIncludes(includes) : '';
let body = JSON.stringify(formData);
let headers = this._createHeaders();
let options = new RequestOptions({ headers: headers });
return this._http.post(this._apiUrl + endpoint + '?include=' + includeString, body, options);
}
handleError(error: Response) {
// log out the user if we get a 401 message
if (error.json().error.http_code === 401) {
this._tokenStore.destroy();
}
return Observable.throw(error.json().error || 'Server error');
}
private _parseIncludes(includes:Array<String>) {
return includes.join();
}
private _createHeaders() {
return new Headers({ 'Content-Type': 'application/json', 'Authorization': 'bearer ' + localStorage.getItem('token') });
}
}
</code></pre>
<p>In each of my services which use the APIConnector, I have catch methods on the <code>Observable</code>s, to run the <code>handleError</code> closure. e.g.</p>
<pre><code>public createEvent(event:Object) {
let endpoint = this._endpoint;
return this._apiConnector.post('clients/'+this.client+'/events', event, this._defaultIncludes)
.map(res => {
return this._transformer.map('event', <Object[]>res.json());
})
.catch(this._apiConnector.handleError);
}
</code></pre>
<p>However, this gives the following error:</p>
<blockquote>
<p>EXCEPTION: TypeError: Cannot read property 'destroy' of undefined</p>
</blockquote>
<p>Presumably this is because handleError is a closure. I'm unsure of the best way to deal with this, though.</p>
<p>Any thoughts would be greatly appreciated</p>

Fortran Error Meanings
|
<p>I have been following books and PDFs on writing in FORTRAN to write an integration program. I compile the code with gfortran and get several copies of the following errors.</p>
<pre><code>1)Unexpected data declaration statement at (1)
2)Unterminated character constant beginning at (1)
3)Unclassifiable statement at (1)
4)Unexpected STATEMENT FUNCTION statement at (1)
5)Expecting END PROGRAM statement at (1)
6)Syntax error in data declaration at (1)
7)Statement function at (1) is recursive
8)Unexpected IMPLICIT NONE statement at (1)
</code></pre>
<p>I do not know hat they truly mean or how to fix them, google search has proven null and the other topics on this site we about other errors. for Error 5) i put in Program main and end program main like i might in C++ but still got the same result. Error 7) makes no sense, i am trying for recursion in the program. Error 8) i read implicit none was to prevent unnecessary decelerations.</p>
<p>Ill post the code itself but i am more interested in the compiling errors because i still need to fine tune the array data handling, but i cant do that until i get it working.</p>

How to install vuetify 2.0 beta to the new vue cli project?
|
<p>Vuetify 2.0.0-beta.0 has just been released and I want to try it out and play around in a new vue test application.
But I get errors when I try to install it in a fresh new project. Here are the steps I've taken.</p>
<p>I use <code>@vue/cli v3.8.2</code> to create a new project with default settings:</p>
<pre><code>vue create testapp
</code></pre>
<p>which gives me successful result:</p>
<pre><code> Successfully created project testapp.
Get started with the following commands:
$ cd testapp
$ npm run serve
</code></pre>
<p>Then I add vuetify plugin to the project with default (recommended) preset:</p>
<pre><code>cd testapp
vue add vuetify
</code></pre>
<p>which gives me success:</p>
<pre><code> Installing vue-cli-plugin-vuetify...

</code></pre>
<p>Now in <code>package.json</code> I see vuetify version:
<code>"vuetify": "^1.5.5"</code></p>
<p>I now update it to the <code>v2.0.0-beta.0</code> like this:</p>
<pre><code>npm install vuetify@2.0.0-beta.0
</code></pre>
<p>I get success again:</p>
<pre><code>+ vuetify@2.0.0-beta.0

</code></pre>
<p>Now when I try to run it:</p>
<pre><code>npm run serve
</code></pre>
<p>I get error:</p>
<pre><code>> testapp@0.1.0 serve c:\temp\testapp

</code></pre>
<p>If I install sass-loader like this:</p>
<pre><code>npm i -D node-sass sass-loader
</code></pre>
<p>I get success. Then I try to run it again:</p>
<pre><code>npm run serve
</code></pre>
<p>Now again I get different error:</p>
<pre><code> ERROR Failed to compile with 1 errors 6:27:06 PM

</code></pre>
<p>I am stuck here as I don't know how to fix this error. <code>npm install --save vuetify/src/stylus/app.styl</code> obviously don't work. Also I couldn't make it work neither by following official <a href="https://next.vuetifyjs.com/en/getting-started/quick-start#full-install" rel="noreferrer">vuetify page</a> for this beta release.</p>

Error inflating class fragment: Duplicate id , tag null, or parent id with another fragment
|
<p>I am trying to make an app in which when user clicks on item in ListView, the GoogleMaps is displayed.</p>
<p>I have tried following code:</p>
<p><strong>ShowPlacesActivity.java</strong></p>
<pre><code>public class ShowPlaceActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_show_place);
if (savedInstanceState == null) {
getFragmentManager().beginTransaction()
.add(R.id.container_showplaces, new PlaceholderFragment())
.commit();
}
getActionBar().setSubtitle(getString(R.string.activity_showplaces_subtitle));
}
}
</code></pre>
<p><strong>activity_show_place.xml</strong></p>
<pre><code><FrameLayout

</code></pre>
<p><strong>fragment_show_place.xml</strong></p>
<pre><code><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>
</code></pre>
<p>I want to show maps on listview's item click...so, I have implemented two fragments as follows:</p>
<p>In <strong>PlaceholderFragment.java</strong>, I have set <code>onitemclicklistener</code> as: </p>
<pre><code>@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_show_place, container, false);
final MySqliteHelper db = new MySqliteHelper(getActivity().getBaseContext());
listview_places = (ListView)rootView.findViewById(R.id.listView_places);
final PlacesAdapter places_adapter = new PlacesAdapter(getActivity(),R.layout.listview_item_row,places);
listview_places.setAdapter(places_adapter);
listview_places.setLongClickable(true);
listview_places.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position,long id) {
Place place = places_adapter.getItem(position);
String dbvaluename = place.getname();
Place selectedplace = db.getPlace(dbvaluename);
dblatitude = selectedplace.getlatitude();
dblongitude = selectedplace.getlongitude();
dbplacename = place.getname();
maps = new MapsFragment();
Bundle bundle = new Bundle();
bundle.putDouble("dbplacename",dblatitude);
bundle.putDouble("dbplacename",dblongitude);
bundle.putString("dbplacename",dbplacename);
maps.setArguments(bundle);
FragmentManager fm = getFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.container_showplaces,maps);
ft.addToBackStack(null);
ft.commit();
}
});
}
}
</code></pre>
<p>and In <strong>MapsFragment.java</strong>, I have shown maps as:</p>
<pre><code>public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.fragment_maps, container, false);
try {
// Loading map
initilizeMap();
} catch (Exception e) {
e.printStackTrace();
}
return rootView;
}
</code></pre>
<p>When I click first time on ListView's item, it shows the Map...Then, when I select another item, it crashes:</p>
<p><strong>Logcat log:</strong></p>

How to fix `Warning: Text content did not match. Server: "Some Data" Client: "Loading..."`
|
<p>I'm getting this error on initial load of my SSR application:
<code>Warning: Text content did not match. Server: "SOME DATA" Client: "Loading..."</code>
How to initialize client side of the app without setting <code>loading</code> flag to true?</p>
<p>I’m setting up a SSR with react, express and apollo. I get a properly rendered HTML with data from the renderer server, but when client bundle loads up it’s trying to refetch data.
Hydration is set up and all the data from renderer server is injected into the HTML of the page.</p>
<p>/index.js</p>
<pre><code><Query query={GET_USERS} variables={queryVariables}>
{({
loading,
error,
data
}) => {
if (loading) return <p>Loading...</p>;
if (error) return `Error: ${error}`;
return data.users.map(user => <p key={user.id}>{user.login}</p>);
}}
</Query>
</code></pre>
<p>/renderer.js</p>
<pre><code>export default async (req, client) => {
const serverSideApp = (
<ApolloProvider client={client}>
<StaticRouter location={req.path} context={{}}>
<div>{renderRoutes(RoutesList)}</div>
</StaticRouter>
</ApolloProvider>
);
return getDataFromTree(serverSideApp).then(() => {
const content = renderToString(serverSideApp);
return `
<html>
<head></head>
<body>
<div id="root">${content}</div>
<script src="bundle.js"></script>
<script>
window.__APOLLO_STATE__=${serialize(client.extract())}
</script>
</body>
</html>
`;
})
};
</code></pre>
<p>/server.js</p>
<pre><code>const app = express();
app.use(express.static("public"));
app.get("*", (req, res) => {
const httpLink = createHttpLink({
uri: "http://10.10.10.139:4000/",
fetch
});
const client = new ApolloClient({
link: httpLink,
ssrMode: true,
cache: new InMemoryCache()
});
renderer(req, client).then((html) => res.send(html));
});
app.listen(3000, () => {
console.log("Server is up");
});
</code></pre>
<p>/client.js</p>
<pre><code>const httpLink = createHttpLink({
uri: "http://10.10.10.139:4000/"
});
const client = new ApolloClient({
link: httpLink,
cache: new InMemoryCache().restore(window.__APOLLO_STATE__)
});
ReactDOM.hydrate(
<ApolloProvider client={client}>
<BrowserRouter>
<div>{renderRoutes(RoutesList)}</div>
</BrowserRouter>
</ApolloProvider>,
document.getElementById("root")
);
</code></pre>
<p>I expect client side of the app rehydrate server side values and not to trigger <code>loading</code> flag on initial load.</p>

Maven error : Could not find or load main class org.codehaus.plexus.classworlds.launcher.Launcher

<p>I'd been stuck with this simple issue for an hour now. Maven was working fine last week, I don't know what went wrong it gives me this error. I tried all the ways to debug and all the solutions found in StackOverflow and many other places. I even tried replacing M2_HOME path with M3_HOME and MAVEN_HOME. Nothing worked. I'm on OS X. Below is the output of few maven commands. I'll be happy to provide more information</p>

Why incompatible version of Java EE error throw from WebSphere?
|
<p>I was using WebSphere Allication Server version 7.0.0.13 in deploying my application. The war was build using Ant version 1.8.2 to build the war and ear file. When I am installing my application through WebSphere, I hit the following error:</p>
<blockquote>
<p>The EAR file could be corrupt and/or incomplete. Make sure that the
application is at a compatible Java(TM) Platform, Enterprise Edition
(Java EE) level for the current version of WebSphere(R) Application
Server.</p>

[Root exception is org.eclipse.jst.j2ee.commonarchivecore.internal.exception.DeploymentDescriptorLoadException:

<p>May I know what cause the problem? Or did I miss configure something in Ant script? Below are the ANT script for compiling the WAR and EAR.</p>

getting java.lang.reflect.InvocationTargetException while adding a button to layout
|
<p>I am totally new in javafx!!
I tried a very very simple code and I got stuck.
when I tried to add a button to the layout It does not work.
I know this question may be too simple but I really do not know how to fix it.
I would appreciated if you could help me.
This is my code:</p>
<pre><code>import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class Test extends Application{
Button button;
public static void main(String[] args){
launch(args);
}
@Override
public void start(Stage stage) throws Exception {
stage.setTitle("Title");
StackPane layout = new StackPane();
button = new Button();
layout.getChildren().add(button);
Scene scene = new Scene(layout);
stage.setScene(scene);
stage.show();
}
}
</code></pre>
<p>and I got the error:</p>

How to use NPM and install packages inside Visual Studio 2017?
|
<p>I have a simple Visual Studio solution, running ASP.NET Core v2 and building a React app.</p>
<p>Now, I want to install a simple component using the NPM. In this particular example, it could be:</p>
<pre><code>npm install --save react-bootstrap-typeahead
</code></pre>
<p>I want this package to work just in my solution and nowhere else.</p>
<p><strong>My result:</strong></p>
<p>When I run this, I get the following nice error which obviously makes some sense. If NPM believes it can find my project file at <code>'C:\Users\LarsHoldgaard\package.json'</code>, it's out of luck.

<p><strong>My thinking:</strong></p>
<p>Being a <strong>console noob</strong>, I would guess I just needed to change my current folder. But if I run <code>dir</code>, I am in the right folder, and I can see my <code>package.json</code> along with other files.</p>
<p>What is the right way to install components?</p>

My Java program is testing if integer is divisible by 3 or 5, but is just printing every integer, how do I fix it?
|
<p>I am not getting errors at all in my code but it is NOT doing what I want it to - at all. I understand that there is <a href="https://stackoverflow.com/questions/31106668/find-if-a-number-is-divisible-by-3-or-5-fizzbuzz">another question related to divisibility to 3 or 5</a> but I do not think the question relates, as our coding is built completely different. I also find that <a href="https://stackoverflow.com/questions/26700089/java-program-that-prints-out-numbers-that-are-divisible-by-other-numbers">this answer</a>, <a href="https://stackoverflow.com/questions/26675725/java-programming-divisibility-and-counting">this other answer</a>, <a href="https://stackoverflow.com/questions/13792435/java-program-divisibility-test-with-varification-how-do-i-write-this-in-text">or even this answer</a> are not helping me, either.</p>
<p>Anyway, I am trying to use a simple boolean expression to determine if an expression is true or not, then if it is true or not printing different lines. The intended look I would get is something like:</p>
<pre><code>3 is divisible by 3
3 is not divisible by 5
4 is not divisible by 3
4 is not divisible by 5
5 is not divisible by 3
5 is divisible by 5
and so on...
</code></pre>
<p>However, I'm getting this:</p>
<pre><code>3 is divisible by 3
3 is not divisible by 3
3 is divisible by 5
3 is not divisible by 5
and so on...
</code></pre>
<p>Initial problem can be found <a href="https://projecteuler.net/problem=1" rel="nofollow noreferrer">here.</a> Right now I am just experimenting with the code, trying to get myself to a better understanding of Java. I wanted to start by knowing how to separate integers that are divisible by the numbers from integers that are not divisible by the numbers and I figured the best way to test this was to print the lines out. I do not know if I am going in the right direction at ALL here. Can anyone either give me pointers on the current code I have, or some hints, such as links to the corresponding Java commands that I will have to use for this program to work. If you post code that works, so I can see what I should be doing, that is fine too but please explain it to me, then. I don't want to just know what to type, I am trying to develop a solid foundation of programming problem-solving.</p>
<p>Sorry if this is a terrible question, I am EXTREMELY new to programming in general and am completely self-teaching. Give me some pointers, and I can most definitely change the question!</p>
<pre><code>package multiplesof3and5;
public class InitialProgram {
public static void main(String[] args) {
// TODO Auto-generated method stub
int integer1;
integer1 = 0;
boolean divisibleby3 = (integer1 % 3) == 0;
boolean divisibleby5 = (integer1 % 5) == 0;
for( integer1=0; integer1<1000; integer1++){
if(divisibleby3 = true);{
System.out.println(integer1 + " can be divided by 3");}
if(divisibleby3 = false);{
System.out.println(integer1 + " cannot be divided by 3");}
if(divisibleby5 = true);{
System.out.println(integer1 + " can be divided by 5");}
if(divisibleby5 = false);{
System.out.println(integer1 + " cannot be divided by 5");
}
}
}
}

Reactjs: how to modify dynamic child component state or props from parent?
|
<p>I'm essentially trying to make tabs in react, but with some issues.</p>
<p>Here's file <code>page.jsx</code></p>
<pre><code><RadioGroup>
<Button title="A" />
<Button title="B" />
</RadioGroup>
</code></pre>
<p><strong>When you click on button A, the RadioGroup component needs to de-select button B</strong>.</p>
<p>"Selected" just means a className from a state or property</p>
<p>Here's <code>RadioGroup.jsx</code>:</p>
<pre><code>module.exports = React.createClass({
onChange: function( e ) {
// How to modify children properties here???
},
render: function() {
return (<div onChange={this.onChange}>
{this.props.children}
</div>);
}
});
</code></pre>
<p>The source of <code>Button.jsx</code> doesn't really matter, it has a regular HTML radio button that triggers the native DOM <code>onChange</code> event</p>
<p><strong>The expected flow is:</strong></p>
<ul>
<li>Click on Button "A"</li>
<li>Button "A" triggers onChange, native DOM event, which bubbles up to RadioGroup</li>
<li>RadioGroup onChange listener is called</li>
<li><strong>RadioGroup needs to de-select button B</strong>. This is my question.</li>
</ul>
<p>Here's the main problem I'm encountering: I <strong>cannot move <code><Button></code>s into <code>RadioGroup</code></strong>, because the structure of this is such that the children are <strong>arbitrary</strong>. That is, the markup could be</p>
<pre><code><RadioGroup>
<Button title="A" />
<Button title="B" />
</RadioGroup>
</code></pre>
<p>or</p>
<pre><code><RadioGroup>
<OtherThing title="A" />
<OtherThing title="B" />
</RadioGroup>
</code></pre>
<p><strong>I've tried a few things.</strong></p>
<p><strong>Attempt:</strong> In <code>RadioGroup</code>'s onChange handler:</p>
<pre><code>React.Children.forEach( this.props.children, function( child ) {
// Set the selected state of each child to be if the underlying <input>
// value matches the child's value
child.setState({ selected: child.props.value === e.target.value });
});
</code></pre>
<p><strong>Problem:</strong></p>
<pre><code>Invalid access to component property "setState" on exports at the top
level. See react-warning-descriptors . Use a static method
instead: <exports />.type.setState(...)
</code></pre>
<hr>
<p><strong>Attempt:</strong> In <code>RadioGroup</code>'s onChange handler:</p>
<pre><code>React.Children.forEach( this.props.children, function( child ) {
child.props.selected = child.props.value === e.target.value;
});
</code></pre>
<p><strong>Problem:</strong> Nothing happens, even I give the <code>Button</code> class a <code>componentWillReceiveProps</code> method</p>
<hr>
<p><strong>Attempt:</strong> I attempted to pass some specific state of the parent to the children, so I can just update the parent state and have the children respond automatically. In the render function of RadioGroup:</p>
<pre><code>React.Children.forEach( this.props.children, function( item ) {
this.transferPropsTo( item );
}, this);
</code></pre>
<p><strong>Problem:</strong></p>
<pre><code>Failed to make request: Error: Invariant Violation: exports: You can't call
transferPropsTo() on a component that you don't own, exports. This usually
means you are calling transferPropsTo() on a component passed in as props
or children.
</code></pre>
<hr>
<p><strong>Bad solution #1</strong>: Use react-addons.js <a href="http://facebook.github.io/react/docs/clone-with-props.html" rel="noreferrer">cloneWithProps</a> method to clone the children at render time in <code>RadioGroup</code> to be able to pass them properties</p>
<p><strong>Bad solution #2</strong>: Implement an abstraction around HTML / JSX so that I can pass in the properties dynamically (kill me):</p>
<pre><code><RadioGroup items=[

Install APK using root, handling new limitations of "/data/local/tmp/" folder
|
<h2>Background</h2>
<p>So far, I was able to install APK files using root (within the app), via this code:</p>
<pre><code>pm install -t -f fullPathToApkFile
</code></pre>
<p>and if I want to (try to) install to sd-card :</p>
<pre><code>pm install -t -s fullPathToApkFile
</code></pre>
<h2>The problem</h2>
<p>Recently, not sure from which Android version (issue exists on Android P beta, at least), the above method fails, showing me this message:</p>
<pre><code>avc: denied { read } for scontext=u:r:system_server:s0 tcontext=u:object_r:sdcardfs:s0 tclass=file permissive=0
System server has no access to read file context u:object_r:sdcardfs:s0 (from path /storage/emulated/0/Download/FDroid.apk, context u:r:system_server:s0)
Error: Unable to open file: /storage/emulated/0/Download/FDroid.apk
Consider using a file under /data/local/tmp/

<p>This seems to also affect popular apps such as "<a href="https://play.google.com/store/apps/details?id=com.keramidas.TitaniumBackup&hl=en" rel="noreferrer"><strong>Titanium backup</strong></a> (pro)", which fails to restore apps.</p>
<h2>What I've tried</h2>
<p>Looking at what's written, it appears it lacks permission to install APK files that are not in <code>/data/local/tmp/</code>.</p>
<p>So I tried the next things, to see if I can overcome it:</p>
<ol>
<li>set the access to the file (<code>chmod 777</code>) - didn't help.</li>
<li>grant permissions to my app, of both storage and <a href="https://developer.android.com/reference/android/Manifest.permission.html#REQUEST_INSTALL_PACKAGES" rel="noreferrer"><strong>REQUEST_INSTALL_PACKAGES</strong></a> (using <a href="https://developer.android.com/reference/android/provider/Settings#ACTION_MANAGE_UNKNOWN_APP_SOURCES" rel="noreferrer"><strong>ACTION_MANAGE_UNKNOWN_APP_SOURCES</strong></a> Intent) - didn't help.</li>
<li><p>create a symlink to the file, so that it will be inside the <code>/data/local/tmp/</code>, using official API:</p>
<pre><code> Os.symlink(fullPathToApkFile, symLinkFilePath)
</code></pre>
<p>This didn't do anything.</p></li>
<li><p>create a symlink using this :</p>
<pre><code> ln -sf $fullPathToApkFile $symLinkFilePath
</code></pre>
<p>This partially worked. The file is there, as I can see it in Total Commander app, but when I try to check if it exists there, and when I try to install the APK from there, it fails. </p></li>
<li><p>Copy/move (using <code>cp</code> or <code>mv</code>) the file to the <code>/data/local/tmp/</code> path, and then install from there. This worked, but it has disadvantages: moving is risky because it temporarily hides the original file, and it changes the timestamp of the original file. Copying is bad because of using extra space just for installing (even temporarily) and because it wastes time in doing so.</p></li>
<li><p>Copy the APK file, telling it to avoid actual copy (meaning hard link), using this command (taken from <a href="https://superuser.com/a/220216/152400"><strong>here</strong></a>) :</p>
<pre><code> cp -p -r -l $fullPathToApkFile $tempFileParentPath"
</code></pre>
<p>This didn't work. It got me this error:</p>
<pre><code> cp: /data/local/tmp/test.apk: Cross-device link
</code></pre></li>
<li><p>Checking what happens in other cases of installing apps. When you install via via the IDE, it actually does create the APK file in this special path, but if you install via the Play Store, simple APK install (via Intent) or adb (via PC), it doesn't.</p></li>
<li><p>Wrote about this here too: <a href="https://issuetracker.google.com/issues/80270303" rel="noreferrer">https://issuetracker.google.com/issues/80270303</a></p></li>
</ol>
<h2>The questions</h2>
<ol>
<li><p>Is there any way to overcome the disadvantages of installing the APK using root on this special path? Maybe even avoid handling this path at all?</p></li>
<li><p>Why does the OS suddenly require to use this path? Why not use the original path instead, just like in the other methods of installing apps? What do the other methods of installing apps do, that somehow avoids using the spacial path?</p></li>
</ol>

Why am I receiving a "Plugin execution not covered by lifecycle configuration with GWT" error?

Adding Spaces between words and making every word except the first lowercase in java
|
<p>I'll go ahead and let you know that yes, this is homework. I have hit a brick wall in completing it however and desperately need help. I'm also pretty new to Java and am still learning the language.</p>
<p>Okay, I am trying to write a program that asks the user to enter a sentence with no spaces but have them capitalize the first letter of each word. The program should then add spaces between the words and have only the first word capitalized, the rest should start with a lowercase. I can get the space inserted between the words, but I cannot get the first letter of each word lower-cased. I have tried several different ways, and the latest one is giving me this error message:</p>

<p>Time can vary.</p>
<p>Results on left I get with:</p>

<p>I have read that there are some issues if I use <code>count</code> and also that it would be better if I use <code>CASE</code> and <code>GROUP BY</code>, however I have no idea how to <code>CASE</code> this.</p>
<p><code>Crosstab</code> itself doesnt support dynamic creation of column names, but that can be achieved with <code>crosstab_hash</code>, if I understood it correctly.</p>
<p>This might be probably nice solution: <a href="http://okbob.blogspot.ca/2008/08/using-cursors-for-generating-cross.html" rel="noreferrer">http://okbob.blogspot.ca/2008/08/using-cursors-for-generating-cross.html</a> however I am stucked with it trying to program it myself.</p>
<p>I have to use this kind of pivoting quite often, so I would appriciate any kind of help and additional explanation behind it.</p>
<p><strong>Edit1</strong></p>
<p>I am trying to figure out how crosstab works with dates, currently without returning dynamic names of columns. Later on I will explain why. It is realted to the main question. For this example I am using only period of 2 dates.</p>
<p>Based on @Erwin Brandstetter answer:</p>
<pre><code>SELECT * FROM crosstab(
'SELECT zoom, day, point
FROM province
ORDER BY 1, 2'
, $$VALUES ('2015-10-01'::date), ('2015-10-02')$$)
AS ct (zoom text, day1 int, day2 int);
</code></pre>
<p>returned results are:</p>
<pre><code>zoom | day1 | day2 |
-----+------------+-------------+
1 | 201 | 685 |
2 | 43 | 346 |
3 | 80 | 534 |
4 | 324 | 786 |

<p>I am trying to get this</p>
<pre><code>zoom | 2015-10-01 | 2015-10-02 |

1 | 201 | 685 |
2 | 43 | 346 |
3 | 80 | 534 |
4 | 324 | 786 |
</code></pre>
<p>but my query doesnt work:</p>
<pre><code>SELECT *

AS ct (zoom text, "2015-10-01" date, "2015-10-02" date);
ERROR: return and sql tuple descriptions are incompatible
</code></pre>
<p><strong>Edit1, Q1. Why does this doesnt work and how can I return results like that?</strong></p>
<p>I have read links that @Erwin Brandstetter provided me, especially this one: <a href="https://stackoverflow.com/questions/36804551/execute-a-dynamic-crosstab-query/36831103#36831103">Execute a dynamic crosstab query</a>. I have copied/pasted his function:</p>

<p>and call it with query</p>

<p>So when I edited the query and added ; (it would be nice that ; is already there) I got:</p>

Spring websocket send to specific people
|
<p>I have added custom token based authentication for my spring-web app and extending the same for spring websocket as shown below</p>
<pre><code>public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
@Override
public void configureMessageBroker(MessageBrokerRegistry config) {
config.enableSimpleBroker("/topic", "/queue");
config.setApplicationDestinationPrefixes("/app");
config.setUserDestinationPrefix("/user");
}
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/gs-guide-websocket").setAllowedOrigins("*").withSockJS();
}
@Override
public void configureClientInboundChannel(ChannelRegistration registration) {
registration.setInterceptors(new ChannelInterceptorAdapter() {
@Override
public Message<?> preSend(Message<?> message, MessageChannel channel) {
StompHeaderAccessor accessor =
MessageHeaderAccessor.getAccessor(message, StompHeaderAccessor.class);
if (StompCommand.CONNECT.equals(accessor.getCommand())) {
String jwtToken = accessor.getFirstNativeHeader("Auth-Token");
if (!StringUtils.isEmpty(jwtToken)) {
Authentication auth = tokenService.retrieveUserAuthToken(jwtToken);
SecurityContextHolder.getContext().setAuthentication(auth);
accessor.setUser(auth);
//for Auth-Token '12345token' the user name is 'user1' as auth.getName() returns 'user1'
}
}
return message;
}
});
}
}
</code></pre>
<p>The client side code to connect to the socket is</p>
<pre><code>var socket = new SockJS('http://localhost:8080/gs-guide-websocket');
stompClient = Stomp.over(socket);
stompClient.connect({'Auth-Token': '12345token'}, function (frame) {
stompClient.subscribe('/user/queue/greetings', function (greeting) {
alert(greeting.body);
});
});
</code></pre>
<p>And from my controller I am sending message as </p>
<pre><code>messagingTemplate.convertAndSendToUser("user1", "/queue/greetings", "Hi User1");
</code></pre>
<p>For the auth token <code>12345token</code> the user name is <code>user1</code>. But when I send a message to <code>user1</code>, its not received at the client end. Is there anything I am missing with this?</p>

Cannot set headers after they are sent to the client with express-validator, express, mongoose and Next.js
|
<p>I am building a login/registration form using <a href="https://express-validator.github.io/docs/custom-validators-sanitizers.html" rel="nofollow noreferrer">express-validator</a> and <a href="https://mongoosejs.com/docs/queries.html" rel="nofollow noreferrer">mongoose</a> in <a href="https://nextjs.org/" rel="nofollow noreferrer">next.js</a>. </p>
<p>Heard the best practice was to sanitize your data on the front <em>and</em> backend.</p>
<p>I have some validations on the frontend (i.e. checking if an email via Regex and making sure a password in a particular length). </p>
<p>But now I'd like to use <a href="https://express-validator.github.io/docs/custom-validators-sanitizers.html#custom-validator" rel="nofollow noreferrer">Custom validator</a> to check if a email exists in my mongodb database. </p>
<pre><code> .post(body('username').custom(value => {
UserModel.findOne({ 'email': value }).then(user => {
if (user) {
return Promise.reject('E-mail already in use');
}
});
}),
</code></pre>
<p>This is the rest of my code:</p>
<pre><code>var router = require('express').Router()
var UserModel = require('../models/UserModel')
var { body } = require('express-validator');
router
.route('/registration')
.get(function(req, res) {
UserModel.find({}, (err, users) => {
if (err) res.status(500).send(err)
res.json(users)
})
})
.post(body('username').custom(value => {
UserModel.findOne({ 'email': value }).then(user => {
if (user) {
return Promise.reject('E-mail already in use');
}
});
}), async(req, res, next) => {
try {
let newUser = new UserModel(req.body)
let savedUser = await newUser.save(err => {
if (err) return res.json({ success: false, error: err })
return res.json({ success: true })
})
if (savedUser) return res.redirect('/users/registration?success=true');
return next(new Error('Failed to save user for unknown reasons'))
} catch (err) {
return next(err)
}
})
module.exports = router

<p>Also do I even need this when Mongoose provides when designing models/schema?</p>
<pre><code>var mongoose = require('mongoose')
var emailValidator = require('email-validator')
var bcrypt = require('bcrypt') // hashing function dedicated for passwords
const SALT_ROUNDS = 12
var UserSchema = new mongoose.Schema(
{
username_email: {
type: String,
required: true,
lowercase: true,
index: { unique: true }, // I mean this!
validate: {
validator: emailValidator.validate,
message: props => `${props.value} is not a valid email address`
}
},
password: {
type: String,
required: true,
trim: true,
index: { unique: true },
minlength: 8
}
},
{
timestamps: true
}
)
UserSchema.pre('save', async function preSave(next) {
var user = this
var hash
if (!user.isModified('password')) return next()
try {
hash = await bcrypt.hash(user.password, SALT_ROUNDS)
user.password = hash
return next()

return next(err)
}
})
UserSchema.methods.comparePassword = async function comparePassword(candidate) {
return bcrypt.compare(candidate, this.password)

module.exports = mongoose.model('User', UserSchema)
</code></pre>
<p>And if I don't does that mean checking if the email exists should be moved to the frontend? And If that's the case how would I approach that?</p>

ASP.NET Core: Create and Open PDF (in browser)

<p>Working in ASP.NET Core and using iTextSharp, I'm building a PDF and save it to the local system. I now want to open that file in the browser but can't seem to make that work since I get a FileStream error in one try and nothing at all in another try.</p>

Rotating a rectangle-shaped Polygon around it's center. (Java)
|
<p>I have this code to draw a rectangle (Polygon object), and then draw another rectangle which is the original one, rotated 90 degrees, using the rotation matrix.</p>
<pre><code>public class DrawingPanel extends JPanel{
public void paintComponent(Graphics g){
super.paintComponent(g);
Graphics2D g2d = (Graphics2D) g;
Point p1,p2,p3,p4;
p1 = new Point(50,50);
p2 = new Point(200,50);
p3 = new Point(200,100);
p4 = new Point(50,100);
int[] x = {(int) p1.getX(), (int) p2.getX(), (int)p3.getX(), (int) p4.getX()};
int[] y = {(int) p1.getY(), (int) p2.getY(), (int)p3.getY(), (int) p4.getY()};
Polygon poly = new Polygon(x, y, x.length);
g2d.draw(poly);
p1.setLocation(p1.getX() * Math.cos(Math.toRadians(90)) - p1.getY() * Math.sin(Math.toRadians(90)),
p1.getX() * Math.sin(Math.toRadians(90)) + p1.getY() * Math.cos(Math.toRadians(90)));
p2.setLocation(p2.getX() * Math.cos(Math.toRadians(90)) - p2.getY() * Math.sin(Math.toRadians(90)),
p2.getX() * Math.sin(Math.toRadians(90)) + p2.getY() * Math.cos(Math.toRadians(90)));
p3.setLocation(p3.getX() * Math.cos(Math.toRadians(90)) - p3.getY() * Math.sin(Math.toRadians(90)),

<p>Currently, the second rectangle doesn't show up. When I asked about this in a different question, someone answered that that's because it draws outside the screen.</p>
<p>I asked how to rotate the rectangle around it's center, so the new drawing will appear in the screen, and he answered but I didn't really understand how to implement what he said in the code (tried different things that didn't work).</p>
<p>Could you show me exactly in the code, how to rotate the rectangle around it's center?</p>
<p>(Of course this isn't actual rotating of an object. It's making a rotated-duplicate of an object).</p>
<p>Help would be appreciated. Thanks</p>

Spring Boot Security CORS
|
<p>I have a problem with CORS filter on spring security URL's.
It doesn't set <code>Access-Control-Allow-Origin</code> and other exposed header on URL's belonging to spring sec (login/logout) or filtered by Spring Security.</p>
<p>Here are the configurations.</p>
<p><strong>CORS:</strong></p>
<pre><code>@Configuration
@EnableWebMvc
public class MyWebMvcConfig extends WebMvcConfigurerAdapter {
********some irrelevant configs************
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/*").allowedOrigins("*").allowedMethods("GET", "POST", "OPTIONS", "PUT")
.allowedHeaders("Content-Type", "X-Requested-With", "accept", "Origin", "Access-Control-Request-Method",
"Access-Control-Request-Headers")
.exposedHeaders("Access-Control-Allow-Origin", "Access-Control-Allow-Credentials")
.allowCredentials(true).maxAge(3600);
}
}
</code></pre>
<p><strong>Security:</strong></p>
<pre><code>@Configuration
@EnableWebSecurity
public class OAuth2SecurityConfiguration extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.exceptionHandling().authenticationEntryPoint(authenticationEntryPoint).and()
.formLogin()
.successHandler(ajaxSuccessHandler)
.failureHandler(ajaxFailureHandler)
.loginProcessingUrl("/authentication")
.passwordParameter("password")
.usernameParameter("username")
.and()
.logout()
.deleteCookies("JSESSIONID")
.invalidateHttpSession(true)
.logoutUrl("/logout")
.logoutSuccessUrl("/")
.and()
.csrf().disable()
.anonymous().disable()
.authorizeRequests()
.antMatchers("/authentication").permitAll()
.antMatchers("/oauth/token").permitAll()
.antMatchers("/admin/*").access("hasRole('ROLE_ADMIN')")
.antMatchers("/user/*").access("hasRole('ROLE_USER')");
}
}
</code></pre>
<p>So, if I make a request to the url's which are not listened by security - CORS headers are set. Spring security URL's - not set.</p>

Partial page rendering with Primefaces - JSF 2.0 navigation
|
<p>I am trying to create a facelet page which updates <code><ui:insert></code> elements with ajax calls. Whenever a <code><p:commandButton action="next"/></code> is clicked ajax call should take place and only <code><ui:insert></code> parts of the facelet template should be updated. My question is exactly same as the question in <a href="https://stackoverflow.com/questions/5685354/partial-page-update-when-navigating-primefaces-ajax">here</a> but the solution over there does not work. Furthermore, considering the comment, it is quite ambiguous if the answer is accepted or not. I am stuck without any solution and not sure if this is related to <a href="http://www.primefaces.org/faq.html" rel="nofollow noreferrer">PrimeFaces FAQ#4</a> </p>
<p>I have another solution proposal with <code><ui:import></code> but not quite sure if this is a good solution. I am storing active page in a bean attribute and updating the value with ajax calls. So any comments and/or ideas are more than appreciated.
Here is my proposal: </p>

Use a simple c++ class in Android NDK
|
<p>I'm trying to learn the basics of Android NDK but I'm stucked when I have to use it with a c++ class.</p>
<p>I understand how to use it with a simple function but what should I do to be able to manipulate the fields and the methods of a c++ class ?</p>
<p>I'm trying to do it with this simple c++ class :</p>
<pre><code>#include <cstdlib>
#include <jni.h>
using namespace std;
class Point {
int x, y; // coordonnées du point
public:
Point() {
this->x = 0;
this->y = 0;
}
Point(int x, int y) {
this->x = x;
this->y = y;
}
int getX() const {
return x;
}
int getY() const {
return y;
}
Point symetrique() const {
return Point(-x, -y);
}
bool operator ==(const Point &p) const {
return this->x == p.getX() && this->y == p.getY();
}
};
extern "C" {
JNIEXPORT jlong JNICALL Java_com_example_jnipoint_JPoint_createPoint__
(JNIEnv *, jobject);
JNIEXPORT jlong JNICALL Java_com_example_jnipoint_JPoint_createPoint__II
(JNIEnv *, jobject, jint, jint);

}
JNIEXPORT jint JNICALL Java_com_example_jnipoint_JPoint_nativeGetY(JNIEnv* env, jobject thiz, jlong nativePointer) {

}
jlong Java_com_example_jnipoint_JPoint_nativeSymetrique(JNIEnv* env, jobject thiz, jlong nativePointer) {
return ((Point*)nativePointer)->symetrique();
}
</code></pre>
<p>I tried to find samples but nothing so far... Maybe I'm not using the right keywords</p>
<p><em><strong></em>* UPDATE <em>*</em></strong></p>
<p>I created a Java wrapper for the c++ Point class and added to the c++ file JNI methods. The code is the following :</p>
<pre><code>public class JPoint {
private long nativePointer;
public JPoint() {
nativePointer = createPoint();
}
public JPoint(int x, int y) {
nativePointer = createPoint(x, y);
}
public int getX() {
return nativeGetX(nativePointer);
}
public int getY() {
return nativeGetY(nativePointer);
}
public JPoint symetrique() {
JPoint tmp = new JPoint();
tmp.nativePointer = nativeSymetrique(nativePointer);
return tmp;
}
// TODO
/*public boolean equals(Object o) {
return nativeEquals(o);
}*/
private native long createPoint(); // Void constructor
private native long createPoint(int x, int y);
private native int nativeGetX(long nativePointer);
private native int nativeGetY(long nativePointer);
private native long nativeSymetrique(long nativePointer);
//private native boolean nativeEquals(Object p); TODO
}
</code></pre>
<p>Right now I'm stucked with the nativeSymetrique function, it says that I cannot convert 'Point' to 'jlong'. Can anyone help me on this ? Thanks</p>
<p><em><strong></em>* UPDATE 2 <em>*</em></strong></p>
<p>SWIG solved my issues, you don't have to handwrite the wrappers and it seems to be a good choice for big libraries.</p>

Resize UILabel to fit text inside custom UITableViewCell regardless of width
|
<p>I'm trying to get a label in a cell to be the right size, regardless of device or orientation. I am able to get the row height to size correctly. I am also able to set the label height correctly in <code>cellForRowAtIndexPath</code>, and can check that in my logs. But, by the time it gets to <code>willDisplayRowAtIndexPath</code>, the label height has changed, but only when the cell is not 320 pts wide.</p>
<p>Here's my code-</p>
<pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"CustomCellIdentifier";
CustomInfoCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil){
cell = [[CustomInfoCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier];
NSArray *objects = [[NSBundle mainBundle] loadNibNamed:@"CustomInfoCell" owner:self options:nil];
cell = objects[0];
}
// Configure the cell...
cell.customTitleLabel.text = [_data[indexPath.row] objectForKey:t];
CGFloat labelWidth = self.view.frame.size.width-40;
NSLog(@"labelWidth:%f",labelWidth);
NSString *text = [_data[indexPath.row] objectForKey:d];//correct text
CGSize labelsize=[text sizeWithFont:cell.customDetailLabel.font constrainedToSize:CGSizeMake(labelWidth, 2000.0) lineBreakMode:cell.customDetailLabel.lineBreakMode];
NSLog(@"labelsize:%f,%f",labelsize.width,labelsize.height);
//For testing
cell.customDetailLabel.backgroundColor = [UIColor redColor];
NSLog(@"Pre: %@",cell.customDetailLabel);
cell.customDetailLabel.frame=CGRectMake(20, 22, labelWidth, labelsize.height);
cell.customDetailLabel.text = text;
NSLog(@"Post: %@",cell.customDetailLabel);
return cell;
}
</code></pre>
<p>In <code>willDisplayRowAtIndexPath</code> I also print the label info. Here's what one row prints-</p>
<pre><code>2013-03-24 18:33:44.009 Bridge Alert[57793:1e503] labelWidth:728.000000
2013-03-24 18:33:44.010 Bridge Alert[57793:1e503] labelsize:713.000000,76.000000
2013-03-24 18:33:44.010 Bridge Alert[57793:1e503] Pre: <UILabel: 0xad3eaf0; frame = (20 20; 280 21); text = 'Detail'; clipsToBounds = YES; opaque = NO; autoresize = RM+BM; userInteractionEnabled = NO; layer = <CALayer: 0x17372eb0>>
2013-03-24 18:33:44.011 Bridge Alert[57793:1e503] Post: <UILabel: 0xad3eaf0; frame = (20 22; 728 76); text = 'Detail'; clipsToBounds = YES; opaque = NO; autoresize = RM+BM; userInteractionEnabled = NO; layer = <CALayer: 0x17372eb0>>
2013-03-24 18:33:44.011 Bridge Alert[57793:1e503] Text set: <UILabel: 0xad3eaf0; frame = (20 22; 728 76); text = 'A bridge is considered “f...'; clipsToBounds = YES; opaque = NO; autoresize = RM+BM; userInteractionEnabled = NO; layer = <CALayer: 0x17372eb0>>
2013-03-24 18:33:44.014 Bridge Alert[57793:1e503] Display:<UILabel: 0xad3eaf0; frame = (20 20; 728 190); text = 'A bridge is considered “f...'; clipsToBounds = YES; opaque = NO; autoresize = RM+BM; userInteractionEnabled = NO; layer = <CALayer: 0x17372eb0>>
</code></pre>
<p>As you can see, by Display, the label is resized. I'm assuming the height is recalculated somehow, based on if the cell were 320 pt wide, which is the built in UITableViewCell width.</p>
<p>How can I get the label to size correctly?</p>

<p>At the start all looks great, it loads the 1st ajax call with all the pics and data.</p>
<p>Then when I click at one of the li's with the ng-click the 2nd ajax gets executed twice, once it gets the right data and immediately after it calls itself again with the initial call of getVODCatalogData(null, $scope.VODCatalogLevel); and brings back the old view.</p>
<p>When I tried to put something in module.run it also runs twice, can it help?</p>
<p>I would appreciate any hint and help as it is my 1st time with angular.</p>
<p>thx!
ariel</p>
<p>EDIT:
some more info - I put a log at the beginning of the controller and after the click the controller gets initialized again</p>

How to render a view inside of other twig + Modal Dialog Symfony2
|
<p>Today I wanna a show a <a href="http://bootboxjs.com/" rel="nofollow">modal dialog</a> with a form</p>
<p>This is my code of main:</p>
<pre class="lang-html prettyprint-override"><code><button class="btn btn-primary btn-lg btn-new" data-toggle="modal" data-target="#agregarPunto">
Nueva Ronda
</button>
<div style="display: none;" class="modal fade" id="agregarPunto" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
<h4 class="modal-title" id="myModalLabel">Agregar ronda</h4>
</div>
<div class="modal-body">
{% embed "controlidMembersBundle:Members:newRonda.html.twig" %}
{% endembed %}
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Cancelar</button>
<button type="button" class="btn btn-primary">Crear ronda</button>
</div>
</div>
</div>
</div>
</code></pre>
<p>This is the code of my view that I wanna embed</p>
<pre><code>{% block nueva_ronda -%}
<h1>Nueva ronda</h1>
{{ form(form) }}
<ul class="record_actions"></ul>
{% endblock %}
</code></pre>
<p>The trouble is when I click on the button, because I get the following error:</p>
<pre class="lang-php prettyprint-override"><code>Variable "form" does not exist in /var/www/html/controlid/src/controlid/Bundle/MembersBundle/Resources/views/Members/newRo nda.html.twig at line 5
</code></pre>
<p>This mistake is obviusly, because I don't know how to call the controller to render the form.</p>
<p>This is the action on symfony that should rendered the form</p>
<pre><code>/*
* @Route("/ronda/crear", name="members_ronda_new")
* @Method("GET")
* @Template()
*/
public function newRondaAction()
{
$entity = new Ronda();
$form = $this->createRondaForm($entity);
return array(
'entity' => $entity,
'form' => $form->createView(),
);
}
</code></pre>
<p>How to embed code inside of my <a href="http://bootboxjs.com/" rel="nofollow">modal-dialog</a> to render the form?</p>

IntelliJ Error: java.lang.OutOfMemoryError: GC overhead limit exceeded
|
<p>I'm running Grails 2.5.0 on IntelliJ Idea Ultimate Edition 2020.2.2 . It compiles and builds the code just fine but it keeps throwing a "java.lang.OutOfMemoryError: GC overhead limit exceeded" error (the entire error is copy and pasted at the end). Here are the things I've tried based off researching this error:</p>
<p>1.) Increasing build process heap size (tried at 2G, 4G, and 6G)
<a href="https://intellij-support.jetbrains.com/hc/en-us/community/posts/360003315120-GC-overhead-limit-exceeded" rel="noreferrer">https://intellij-support.jetbrains.com/hc/en-us/community/posts/360003315120-GC-overhead-limit-exceeded</a></p>
<p>2.) Increasing memory heap size (tried at 2G, 4G, and 6G)
<a href="https://www.jetbrains.com/help/idea/increasing-memory-heap.html" rel="noreferrer">https://www.jetbrains.com/help/idea/increasing-memory-heap.html</a></p>
<p>3.) Increasing the maximum memory setting for the JVM in the launch configuration (tried at 2G, 4G, and 6G)</p>
<p>I saw that one of the fixes for this error is to "Reuse existing objects when possible to save some memory." However I believe strongly that this is not an issue with the code but with settings on my IDE. The code I am using works fine without errors on the production website and this OutOfMemoryError only appears on my local machine. I would appreciate any help anyone can give, thank you!!!</p>
