error in sqlite "DROP TABLE IF EXISTS" android

<p>so i have a problem in my DBAdapter class its just crushes when i try to open the database:
from the LogCat i guess the problem is in the onUpgrade function:</p>
<pre><code> public void onUpgrade(SQLiteDatabase db, int oldVersion,
int newVersion)
{
Log.w("SingleDBAdapter", "Upgrading database from version " + oldVersion
+ " to "
+ newVersion + ", which will destroy all old data");
db.execSQL("DROP TABLE IF EXISTS "+DATABASE_TABLE);
onCreate(db);
}
}

<p>I was trying to create a confusion matrix. It basically contains count of the (i, j) pairs.
I first created a list of lists, and then incremented the appropriate variable. However, it didn't work as expected. CM[i][0] got incremented for all values of i.</p>
<p>I found a work around.</p>
<pre><code>>>> CM = [[0 for _ in range(10)] for _ in range(10)]

Kubernetes AutoScaler Not Scaling, HPA shows target <unknown>

<p>I'm pretty new to kubernetes, not so much with docker.</p>
<p>I've been working through the example but I am stuck with the autoscaler, (which doesn't seem to scale).</p>

css display table cell requires percentage width
|
<p>I've been put in a position where I need to use the display:table-cell command for div elements.</p>
<p>However I've discovered that the "cells" will only work correctly if a percentage is added to the width.</p>
<p>In this fiddle <a href="http://jsfiddle.net/NvTdw/" rel="noreferrer">http://jsfiddle.net/NvTdw/</a> when I remove the percentage width the cells do not have equal widths, however when a percentage value is added to the width all is well, but only when that percentage is equal to the proportion of max no of divs, so for four columns 25%, five 20% and in this case five at 16.666%.</p>
<p>I thought maybe adding a percentage of less - say 1% would be a good fix all, but the cells fall out of line again.</p>
<p>Why is this?</p>

Spring Boot Application failed to start with classpath: []

<p>I generated a Spring Boot application with <a href="http://www.jhipster.tech/" rel="noreferrer">jHipster</a>, added some code from my previous project (non-jhipster project) and tried to run it using IDEA.

How to get items row id of repeater when user clicks rows linkbutton control
|
<p>I have a repeater, nested with Html table rows:</p>
<pre><code><asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
<HeaderTemplate>
<table id="grid">
<thead>
<tr>
<th>SID</th>

<asp:LinkButton runat="server" ID="lbtnPDF" Text="PDF Full Text" OnClick="lbtnPDF_Click" />
</td>
</tr>
</ItemTemplate>
<FooterTemplate>
</tbody>
</table>
</FooterTemplate>
</asp:Repeater>
</code></pre>
<p>When the user clicks on linkbutton, I want to get the ID of that row of repeater item and will display the PDF file which is related to that ID, in another aspx page.</p>
<p>I wrote on itemdatabound event :</p>
<pre><code>protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
LinkButton lnkBtn = (LinkButton)e.Item.FindControl("lbtnPDF");
}
</code></pre>
<p>How can I get column Id of repeater nested with an html table?</p>

How to send file through socket in c#
|
<p>I have server and client console apps which communicate fine as well as sending some string. Here is the code...</p>
<p>Server</p>
<pre><code>public static void Main()
{
try
{
IPAddress ipAd = IPAddress.Parse("127.0.0.1");
/* Initializes the Listener */
TcpListener myList = new TcpListener(ipAd, 1234);
/* Start Listeneting at the specified port */
myList.Start();
Console.WriteLine("The server is running at port 8001...");
Console.WriteLine("The local End point is :" + myList.LocalEndpoint);
Console.WriteLine("Waiting for a connection.....");
Socket s = myList.AcceptSocket();
Console.WriteLine("Connection accepted from " + s.RemoteEndPoint);
byte[] b = new byte[100];
int k = s.Receive(b);
Console.WriteLine("Recieved...");
for (int i = 0; i < k; i++)
Console.Write(Convert.ToChar(b[i]));
ASCIIEncoding asen = new ASCIIEncoding();
s.Send(asen.GetBytes("The string was recieved by the server."));
Console.WriteLine("\nSent Acknowledgement");
/* clean up */
s.Close();
myList.Stop();
}
catch (Exception e)
{
Console.WriteLine("Error..... " + e.StackTrace);
}
}
</code></pre>
<p>Client</p>
<pre><code>public static void Main()
{
try
{
TcpClient tcpclnt = new TcpClient();
Console.WriteLine("Connecting...");
tcpclnt.Connect("127.0.0.1", 1234);
Console.WriteLine("Connected");
Console.Write("Enter the string to be transmitted: ");
String str = Console.ReadLine();
Stream stm = tcpclnt.GetStream();
ASCIIEncoding asen = new ASCIIEncoding();
byte[] ba = asen.GetBytes(str);
Console.WriteLine("Transmitting...");
stm.Write(ba, 0, ba.Length);
byte[] bb = new byte[100];
int k = stm.Read(bb, 0, 100);
for (int i = 0; i < k; i++)
Console.Write(Convert.ToChar(bb[i]));
tcpclnt.Close();
}
catch (Exception e)
{
Console.WriteLine("Error... " + e.StackTrace);
}
}
</code></pre>
<p>Now, I need to add the code algorithm which will send a file through the same apps. The key thing to implement is to use Socket.Send in the client. I am not sure about serialization and de-serialization of the the file.</p>
<p>Any hint, advice, suggestion is more that welcome. Thanks.</p>

Combining a while loop with Task.Run() in C#
|
<p>I'm pretty new to multithread applications in C# and I'm trying to edit my code below so that it runs on multiple threads. Right now it operates synchronously and it takes up very little cpu power. I need it to run much faster on multiple threads. My thought was starting a task for each core and then when a task finishes, allow another to take its place or something like that if it is possible.</p>

How to create a substitution keyword cipher
|
<p>I am trying to develop a substitution cipher that uses a keyword to create a new cipher alphabet. I am new to Java (as I'm sure you will be able to tell!) and I am finding it
hard to wrap my head around the code for what I need to do. </p>
<p>My understanding is as follows:</p>
<p>If for example, the keyword is <code>javben</code>, I should start by finding the index of the "j" in the plainText string array, which is 9. I then want to shift the plainText[9] into cipherText[0] and move each other element over by 1. So the first pass of this would result in:</p>
<pre><code>cipherText[] = {"j","a","b","c","d","e","f","g","h","i","k","l","m","n","o","p","q","r","s","t","u","v","w","r","x","y","z"}
</code></pre>
<p>Then I would find the "a" and it's it's already where it should be so I'll need to account for this and not shift it -- somehow. The next character is the "v" and so the process would continue.</p>
<p>After shifting everything in the cipher I should end up with:</p>
<pre><code>plainText []= {"a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","r","x","y","z"}
cipherText[]= {"j","a","v","b","e","n","c","d","f","g","h","i","k","l","m","o","p","q","r","s","t","u","w","r","x","y","z"}
</code></pre>
<p>As you can see, I am reasonably sure that I understand the process of which to go through, however I am really struggling wrap my head around the code required for this. Help please! </p>

How to add a timeout to a function in Python
|
<p>Many attempts have been made in the past to add timeout functionality in Python such that when a specified time limit expired, waiting code could move on. Unfortunately, previous recipes either allowed the running function to continue running and consuming resources or else killed the function using a platform-specific method of thread termination.

The correct way to declare, alloc, load, and dealloc an NSMutableArray
|
<p>I declare my array in my *.h file:</p>
<pre>
@interface aViewController: UIViewController
{
NSMutableArray *anArray; // You will need to later change this many times.
}
@end
</pre>
<p>I alloc memory for it my *.m file:</p>
<pre>
-(void) viewDidLoad
{
anArray = [[NSMutableArray alloc] init];
}
</pre>
<p>I click a test-button to load my array (eventually it will need to load DIFFERNT values
on each click):</p>
<pre>
anArray = [NSMutableArray arrayWithObjects:@"one", @"two", @"three", nil];
</pre>
<p>And I free it here:</p>
<pre>
-(void) dealloc
{
[anArray release];
[super dealloc];
}
</pre>
<p>Does that all look ok? </p>
<p>Because it crashes when I later run this code:</p>
<pre>
NSLog(@"%d", [anArray count]);
</pre>
<p>Not sure why a simple "NSLog() and count" would crash everything.</p>
<hr>
<p>Dirk,</p>
<p>Let me put it this way: I have a <em>HUGE</em> misunderstanding of pointers, arrays, strings, and memory.</p>
<p>I've read everything I can find on it... but (yet) to find a simple, clear, easy-to-understand description.</p>
<p>Can you suggest one? (Hopefully less than 10 pages of reading.)
Is there a reference that explains <em>JUST</em> this topic... and from a standpoint of "you have 12 years of coding experience... but NONE that ever dealt with allocating memory or pointers".) </p>
<p>So the variable-name is <em>NOT</em> the way I refer to the object?
Then why have it?</p>
<p>I'm used to many other languages that just do this:</p>
<pre>
myString = "this"
myString = "that"
myInt = 5
myInt = 15
</pre>
<p>(What could be simpler.)</p>
<hr>
<p>Looks to me like this would be the easiest way to do this.
(And it seems to work. But it is truly correct?)</p>
<pre>
Don't alloc any memory for my NSMutableArray initially.
Don't re-alloc any memory repeatedly. (When I change my array's values.)
Don't release it repeatedly. (Before I change my array's values.)
Don't release it when I exit the program.
But:
Always remember to use RETAIN when I initially assign
(and repeatedly reassign) new values to my anArray variable.
</pre>
<hr>
<blockquote>
<p>You are not loading your array with
anArray = [NSMutableArray arrayWithObjects:@"one", @"two", @"three", nil];
Instead, you are replacing it with a new instance, and worse: with an instance, whose
reference is actually owned by some entity you do not control </p>
</blockquote>
<p>Wow. So I could have 20 arrays... all called the same name: anArray... and they would be all different? (There's no such thing as a GLOBAL array?)</p>
<blockquote>
<p>etc. In order to clear out old values, the method removeAllObject may be handy.
There are also mutation methods, which may be used to add multiple values at once.</p>
</blockquote>
<p>So... first I have to "remove all the objects"... and then I can call <em>ONE</em> method it re-add all my new values.</p>
<blockquote>
<p>anArray = [[NSMutableArray arrayWithObjects:@"one", @"two", @"three", nil] retain];
instead of the alloc/init sequence.</p>
</blockquote>
<p>Wow. I thought nothing could be stored in an array without alloc'ing space for it.</p>
<blockquote>
<p>If you really intend to replace the entire array, you may want to consider
using properties</p>
</blockquote>
<p>How would I do that using properties?<br>
What would be the correct way to do something like this:</p>
<pre>
> anArray = [NSMutableArray arrayWithObjects:@"one", @"two", @"three", nil];
> anArray = [NSMutableArray arrayWithObjects:@"four", @"five", @"six", nil];
</pre>
<p>Just like I would do:</p>
<pre>
x = 12;
x = 24;
</pre>
<hr>
<p>Wow. I <em>REALLY</em> have totally misunderstand everything about strings, arrays, and memory.
I thought the "easy way" was to alloc ONCE... use the mutable array... change it as much as you want... and free it ONCE.</p>
<blockquote>
<p>The problem with doing so is that this new array isn't retained, </p>
</blockquote>
<p>I would think the old array would be gone... and the new array could be used.
(But I guess not.)</p>
<blockquote>
<p>Further, you have a memory leak because you never freed the original array.</p>
</blockquote>
<p>I was thinking the old array wasn't suppose to be freed... I'm not done with it... I just wish to CHANGE it to contain my new values. (But I guess not.)</p>
<blockquote>
<p>but one is to use [anArray release]; </p>
</blockquote>
<p>I was thinking that would cause me to release the memory I allocated... (but I guess not)... and then I'd have to re-alloc more memory. (But I guess not.)</p>
<blockquote>
<p>anArray = [[NSMutableArray arrayWithObjects:@"one", @"two", @"three", nil] retain];</p>
</blockquote>
<p>So I have to "retain" it... so it doesn't disappear out from under me?
(Not sure why it would. Until <em>I</em> tell it to... in my final dealloc call.)</p>
<blockquote>
<p>Another, probably more correct way to fix it would be to use the addObject: or
addObjectsFromArray: NSMutableArray methods instead of constantly creating new arrays.</p>
</blockquote>
<p>I only want to create <em>ONE</em> array... and just use it as I want to.
I never want to <em>ADD</em> to the array. I want to set it to my new values.</p>

Programmatically log a user in to asp.net membership and roles?
|
<p>I'm working on an Asp.Net 4.0 web application which is using the Membership and Roles features of Asp.Net.</p>
<p>In the application, there will be three roles which have access to the login page and one role which doesn't.</p>
<p>The way it is supposed to work is as follows.</p>
<p>Back end user (in one of the three privileged roles) creates a user. In the code, this is done programmatically rather than using the Register User page. When the user is created, they are added to the unprivileged role, which, for the sake of clarity is called the Visitor role.</p>
<p>Back end user then creates a link for the new user which is in the form of <a href="https://www.example.com?link=cc82ae24-df47-4dbf-9440-1a6923945cf2" rel="nofollow noreferrer">https://www.example.com?link=cc82ae24-df47-4dbf-9440-1a6923945cf2</a></p>
<p>When the link is visited, the application will locate the user associated with the query string, get the username and password (which are suitably hashed and salted) and logs the user in.</p>
<p>This is where I'm coming undone. So far, the user creation is working just fine, the database query based on the value of the query string is doing its job and returning the relevant bits of information, it all seems to be flowing pretty well, except for the actual logging in. There doesn't seem to be a clear method of logging a user in programmatically, without going through the rigmarole of getting the user to log themselves in, which I have been explicitly told to avoid.</p>
<p>Here is my code, the "pers" object is a class which is populated from the database when they land on the default page of the link:</p>
<pre><code>protected void LogUserIn(string p)
{
SqlConnection conn = UtilityMethods.GetConnection();
Guid par = Guid.Parse(p);
BioProspect pers= new BioProspect(conn);
pers.FillDetailsFromDb(par);
testlable.Text = pers.ToString();
Response.Cookies.Remove(FormsAuthentication.FormsCookieName);
try
{
if (Membership.ValidateUser(pers.Email, pers.Pword))
{
FormsAuthentication.SetAuthCookie(pers.Email, true);
Response.Redirect(Request.Url.Scheme + "://" + Request.Url.Host + "/About.aspx");
testlable.Text = "Logged in!";
}
else
{
throw new Exception("Something went wrong");
}
}
catch (Exception ex)
{
StringBuilder sb = new StringBuilder();
foreach (DictionaryEntry d in ex.Data)
{
sb.Append(d.Key.ToString());
sb.Append(": ");
sb.Append(d.Value.ToString());
sb.Append("\r\n");
}
AMessage(sb.ToString());
}
}
</code></pre>
<p>Now, I've checked the values of the username and password against the database table itself and it is all correct. I understand the password stored in the aspnet tables has been salted and hashed, so I'm checking the values in a temporary table I created to hold the clear text. It's right. In addition, in the code above, the FormsAuthentication.SetAuthCookie method is asking for a username and password - in this instance, the username is the email address. This information is also correct when inspected during debugging.</p>
<p>I should point out, the links we are sending are pretty much one time links. Every time a change is made relevant to that particular user, the value of the link parameter will change and the old link will be come completely useless. The page they will be redirected to will hold documents which are directly relevant to that particular user and to no others.</p>
<p>However, we still need the benefits of the Asp.Net Membership, Profiles and Roles framework, since the "Visitor" may well have several links sent to them, with different documents and versions of documents being added and changed over time.</p>
<p>Can anyone think of a better way? I have so far looked at most of the relevant entries <a href="https://stackoverflow.com/search?q=[asp.net]+auto+login">here</a> and <a href="https://stackoverflow.com/search?q=[asp.net]+automated+login">here</a> but they all seem somewhat incomplete.</p>
<p><strong>EDIT</strong></p>
<p>I seem to have at least partially resolved this, using information gleaned from the accepted answer <a href="https://stackoverflow.com/questions/2730020/membership-validateuser-always-returns-false-after-upgrade-to-vs-2010-net-4-0">here</a></p>
<p>Essentially, the problem was my web.config membership section needed to be told which hashing algorithm to use. At the moment, I have no idea what the default one is, if there is one, but adding</p>
<pre><code><membership hashAlgorithmType="SHA1">
</code></pre>
<p>to the web.config has at least allowed me to log in users created after the above line was added. The next step is for me to understand why I can't get the other users logged in.</p>
<p>I am however still getting a ThreadAbortException as suggested by Joe, which I am now busily working to resolve. </p>

Enable SOAP on Plesk
|
<p>This question has been asked before but none of the solutions work for me. I was mainly following this one - <a href="https://stackoverflow.com/questions/11014431/enable-soap-on-php">enable SOAP on PHP</a> to no avail. I have a php script which is giving the following error:</p>
<pre><code>Error message: Fatal error: Class 'SoapClient' not found in /var/www/pathtofile/file.php on line 90
</code></pre>
<p>I guess need to install soap on a Plesk 11.0.9 and CentOS 5.6 (Final). This is what I have by default in the php.ini file:</p>
<pre><code>[soap]
; Enables or disables WSDL caching feature.
soap.wsdl_cache_enabled=1
; Sets the directory name where SOAP extension will put cache files.
soap.wsdl_cache_dir="/tmp"
; (time to live) Sets the number of second while cached file will be used
; instead of original one.
soap.wsdl_cache_ttl=86400
</code></pre>
<p>and <strong>php -i | grep soap</strong> gives me:</p>
<pre><code>'--enable-soap=shared'
</code></pre>
<p>if I run <strong>yum install php-soap</strong> I get the following:</p>

How to use ts-node ESM with node modules?

<p>Note: I am aware that the following question is about an experimental feature. I have created a <a href="https://github.com/TypeStrong/ts-node/discussions/1321" rel="noreferrer">clone on the ts-node discussion forum</a>. However, I believe StackOverflow has a wider exposure and would lead to a solution in less time.</p>
<p>I am trying to make a simple script that reads a file from one location and processes it. Here is what I have so far, having followed <a href="https://github.com/TypeStrong/ts-node/issues/1007" rel="noreferrer">#1007</a>:</p>

MySQL: How to Combine multiple SELECT queries, using different WHERE criteria on the same table?
|
<p>I have been trying many different ways to solve this problem from this forum and from many others. I can't seem to find a solution to this problem or any documentation that will give me a straight answer.</p>
<p>I wondered if you could have a look at it for me.</p>
<p>Thanks</p>
<p><strong>THE PROBLEM:</strong></p>
<p>I've got a database with the following tables
participant_scores
leagues
rounds</p>
<p>I am currently able to display the scores of a single round, one round at a time... which is exactly how I want it.
But I also want to display the score that each participant got for all rounds.
Lets say we have 2 rounds. I want the output on my results screen to look something like this:</p>
<pre><code> Currently viewing league 20, Round 1
of 2:
User Name | Score | Total Score
Tom | 10 | 200
James | 50 | 300
</code></pre>
<p>username - the participant's name
score = the score for this current round
total score = all of the round scores for this league added together.</p>
<p>My Mysql query is below. Apologies for the messyness of it, I've rewritten it about 100 times and this current way is the only way that works fully.</p>
<h1>>> league_participants_query (mysql)</h1>
<pre><code> # FIELDS
SELECT
participants.participant_id, # ID - used for functions
participants.participant_name, # NAME
participants.participant_gender, # Participant info
classes.class_name, # Class name

<p>i want to convert string in my constructor into double, i can't change it in my constructor, because in one process, the variable must in double, and other class must be string, can you tell me the way to convert it..? this is my constructor :</p>
<pre><code>public class DataItem {
String ijiInvest, ijiId;
String tanggal;
double persenHmint1,inuNilai selisih,persen_hke1;

Qt 5 : Mouse Wheel event behaviour for zooming image
|
<p>I have a window, in which is a QGraphicsView, which will be displaying an image. I have implemented the wheelEvent(). My images are mostly going to be bigger than the window, so I get scroll bars in the window.</p>
<p>What we normally observe when we rotate the wheel while viewing an image in Windows Photo Viewer is that when we move the wheel up (towards it's wire), the image zooms in and when we move it down (towards out body), the image zooms out.</p>
<p>What I am getting instead is when I move the wheel towards myself (to zoom out) the image instead of zooming out , first scrolls down, and starts zooming out only when the scroll bar touches its bottom most point.</p>
<p><strong>It would be better to understand the problem by trying out the code. I am not able to explain in I guess.</strong></p>
<p>I want the standard behavior. What to do?</p>

How to use Key Bindings instead of Key Listeners

Authentication in jQuery Mobile and PhoneGap
|
<p>I have a web application built with jQuery Mobile and PHP (CodeIgniter framework). Now I'm trying to make a PhoneGap version of it as well, to make it distributable as a standalone app. However, the PHP web app. version uses Ion Auth, a CodeIgniter plugin for authentication. So when you go to a page that requires authentication, the app redirects you to the authentication controller login method. And after authentication it redirects you back to the home page (the jQuery Mobile page in this case). This works fine in the web app., since the home page is opened by the home controller in the first place anyway.</p>
<p>But here's the crux: in the PhoneGap version, the "home" page needs to be the index.html file in PhoneGap. Apparently you can load another url on startup by adding a value in PhoneGap.plist, but that is not acceptable by apple for submitting to app store. And if I do a redirect in the authentication, I can't get back to the index.html file after authentication...</p>
<p>So how should one go about authentication in a PhoneGap/jQuery Mobile app?</p>
<p>UPDATE:</p>
<p>I have tried this according to one of the answers, but the app still tries to navigate to the account/login page (which doesn't exist), when I just want to login through the post and return a value from the method:</p>
<pre><code> $('#login_form').bind('submit', function () {
event.preventDefault();
//send a post request to your web-service
$.post('http://localhost/app_xcode/account/login', $(this).serialize(), function (response) {
//parse the response string into an object
var response = response;
//check if the authorization was successful or not
if (response == true) {
$.mobile.changePage('#toc', "slide");
} else {
alert('login failed');
$.mobile.changePage('#toc', "slide");
}
});
});
</code></pre>
<p>Here's the controller method:</p>
<pre><code>function login()
{
//validate form input
$this->form_validation->set_rules('identity', 'Identity', 'required');
$this->form_validation->set_rules('password', 'Password', 'required');
$base_url = $this->config->item('base_url');
$mobile = $this->detect_mobile();
if ($mobile === false && $base_url != 'http://localhost/app_xcode/') //Only restrict if not developing
redirect('account/notAMobile');
else if ($this->form_validation->run() == true) { //check to see if the user is logging in
//check for "remember me"
$remember = (bool)$this->input->post('remember');
if ($this->ion_auth->login($this->input->post('identity'), $this->input->post('password'), $remember)) { //if the login is successful
//redirect them back to the home page
$this->session->set_flashdata('message', $this->ion_auth->messages());
echo true;
/*redirect($this->config->item('base_url'), 'refresh');*/
}
else
{ //if the login was un-successful
//redirect them back to the login page
$this->session->set_flashdata('message', $this->ion_auth->errors());
/*redirect('account/login', 'refresh');*/ //use redirects instead of loading views for compatibility with MY_Controller libraries
}
}
else
{ //the user is not logging in so display the login page
//set the flash data error message if there is one
$this->data['message'] = (validation_errors()) ? validation_errors()
: $this->session->flashdata('message');
$this->data['identity'] = array('name' => 'identity',
'id' => 'identity',
'type' => 'text',
'value' => $this->form_validation->set_value('identity'),
);
$this->data['password'] = array('name' => 'password',
'id' => 'password',
'type' => 'password',
);
}
}
</code></pre>
<p>I think I have removed or commented out any redirects that were there. So I don't know why it tries to load the view still? Does it have something to do with jQuery Mobile trying to navigate there because I post to that url?</p>

<p>Width and height values are correct 320 x 480 but image which I'm setting as a wallpaper is still more bigger then my device scren.</p>
<p>After test on my real phone LG L5 with new android (not sure which version). Image is set as wallpaper correct (in portrait mode - 1 image for all 5 "roll screens" without scaling).</p>
<p>How can i tested it on other devices ?
Mean... is this portrait mode for wallpapers is available only in new android version ?</p>

Trying to change main activity background color on button click
|
<p>Here's my main:</p>
<pre><code>@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_menu);
Button btn = (Button) findViewById(R.id.newgame_button);
btn.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v) {
changeBackground(v);
}
});
}
</code></pre>
<p>I've tried the follow methods, both of which have failed:</p>
<pre><code>public void changeBackground(View v)
{
View someView = findViewById(R.id.main);
View root = someView.getRootView();
root.setBackgroundColor(getResources().getColor(R.color.red));
}
public void changeBackground(View v)
{
View root = v.getRootView();
root.setBackgroundColor(getResources().getColor(R.color.red));
}
</code></pre>
<p>I searched and found the solution for how to solve this in <a href="https://stackoverflow.com/questions/4761686/how-to-set-background-color-of-activity-to-white-programmatically">How to set background color of Activity to white programmatically?</a>; the solution posted was:</p>
<pre><code> // Now get a handle to any View contained
// within the main layout you are using
View someView = findViewById(R.id.randomViewInMainLayout);
// Find the root view
View root = someView.getRootView()
// Set the color
root.setBackgroundColor(android.R.color.red);
</code></pre>
<p>When I try <code>android.R.color.red</code>, eclipse tells me that it should be in the form in my examples.</p>
<p>I did manage to change the background of my button with:</p>
<pre><code>public void changeBackground(View v)
{
v.setBackgroundColor(getResources().getColor(R.color.red));
}
</code></pre>
<p>So, I'm pretty confident that the issue is not with: <code>getResources().getColor(R.color.red)</code>. I've tried many different ways, and I'm not getting anywhere. For reference, here's my xml:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>
</LinearLayout>

Webpack Dev Server (webpack-dev-server) Hot Module Replacement (HMR) Not Working
|
<p>I have gone through many answers on StackOverflow & on GitHub issues as well but, I am still stuck in Hot Module Replacement in Webpack. I am using <code>npm start</code> to run my server with <code>webpack-dev-server --hot --inline</code>. <strong>I am trying to change code in my React component, but nothing happens in the browser</strong>.</p>
<p>I am using Google Chrome Version 49.0.2623.87 (64-bit) on Ubuntu 14.04LTS.</p>
<p>In my browser <code>console</code>, I am getting log messages as</p>

<p>But, no hot/live reload is happening. Nothing gets displayed when I change code in my React component file. I was following first video of this tutorial, <a href="https://egghead.io/lessons/react-react-fundamentals-development-environment-setup" rel="nofollow noreferrer">Egghead.io/ReactFundamentals</a> where everything worked fine.</p>

MVVM DataGrid SelectedItem binding doesn’t get updated
|
<p>I’m new to .Net and C# and a little bit confused with bindings. I have application that implements MVVM and displays DataGrid. What I want to implement is when user presses certain key combination then the content of currently selected cell gets copied to the cell in the row below.
I have tried binding the SelectedItem of DataGrid to the ViewModel property but it never gets updated. CommandParameter also didn’t work, item count is always 0.
So I cannot extract what cell the user has selected and cannot read the content of the selected cell.
Does anyone have suggestions how to solve this problem or implement this functionality?
Thanks in advance.
code:
xaml:</p>
<pre><code><DataGrid Grid.Row="1"
Grid.Column="0"
Grid.ColumnSpan="9"
AutoGenerateColumns="False"
Height="Auto"

ScrollViewer.CanContentScroll="False"
FrozenColumnCount="1"
SelectionUnit="Cell"
SelectionMode="Extended"
CanUserSortColumns = "False"
CanUserReorderColumns="False"
CanUserResizeRows="False"
RowHeight="25"
RowBackground="LightGray"
AlternatingRowBackground="White"
ScrollViewer.VerticalScrollBarVisibility="Visible"
ScrollViewer.HorizontalScrollBarVisibility="Visible"
ItemsSource="{Binding Layers, Mode=TwoWay}"

<DataGrid.InputBindings>
<KeyBinding Gesture="Shift"

</KeyBinding>
</DataGrid.InputBindings>
</DataGrid>

}
set
{

{
_selection = value;
NotifyPropertyChanged("Selection");
}
}
}
</code></pre>
<p>...</p>
<pre><code> public DelegateCommand<IList> SelectionChangedCommand = new DelegateCommand<IList>(

PostgreSQL error 'Could not connect to server: No such file or directory'
|
<p>Like some others I am getting this error when I run rake db:migrate in my project or even try most database tasks for my <a href="http://en.wikipedia.org/wiki/Ruby_on_Rails" rel="noreferrer">Ruby on Rails</a> 3.2 applications.</p>
<blockquote>
<p>PGError (could not connect to server: No such file or directory. Is the
server running locally and accepting connections on Unix domain socket
"/tmp/.s.PGSQL.5432"?</p>
</blockquote>
<p>I installed <a href="http://en.wikipedia.org/wiki/PostgreSQL" rel="noreferrer">PostgreSQL</a> with <a href="https://en.wikipedia.org/wiki/Homebrew_%28package_management_software%29" rel="noreferrer">Homebrew</a> a long time ago and following an attempted installation of <a href="http://en.wikipedia.org/wiki/MongoDB" rel="noreferrer">MongoDB</a> recently my PostgreSQL install has never been the same. I'm running OS X v10.6 Snow Leopard.</p>
<p>What's wrong and how do I better understand how PostgreSQL is and should be setup on my Mac?</p>
<p>So far (I think) this tells me that PostgreSQL is not running(?).</p>
<pre><code>ps -aef|grep postgres (ruby-1.9.2-p320@jct-ana) (develop) ✗
501 17604 11329 0 0:00.00 ttys001 0:00.00 grep postgres
</code></pre>
<p>But does this tell me that PostgreSQL is running?</p>
<pre><code>✪ launchctl load -w /usr/local/Cellar/postgresql/9.1.4/homebrew.mxcl.postgresql.plist (ruby-1.9.2-p136)
homebrew.mxcl.postgresql: Already loaded
</code></pre>
<p>How do I fix this? what am I not seeing?</p>
<p>PS: <code>~/Library/LaunchAgents</code> includes two PostgreSQL .plist files. I am not sure if that's relevant.</p>
<pre><code>org.postgresql.postgres.plist
homebrew.mxcl.postgresql.plist
</code></pre>
<p>I tried the following and got a result as below.</p>
<p><strong>$ psql -p 5432 -h localhost</strong> </p>
<pre><code>psql: could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused
Is the server running on host "localhost" (fe80::1) and accepting
TCP/IP connections on port 5432?
</code></pre>
<p>I've read since that this is occuring because OS X installs its own version of PostgreSQL and Homebrew installs a different version in a different place and the PostgreSQL commands are looking in the /tmp/ directory. You'll need to search more on Stack Overflow, but basically you symlink PostgreSQL so that anything looking in that tmp path actually finds the real path, if that makes sense.</p>
<p>This is the link where I found a few more things to try, specifically doing the symlink as per above, <em><a href="https://stackoverflow.com/questions/17240516">Mac OSX Lion Postgres does not accept connections on /tmp/.s.PGSQL.5432</a></em>. I still wish someone would put together a decent explanation of the concepts behind installing PostgreSQL on OS X and why it's all so difficult.</p>
<p>Latest insights to help with troubleshooting:</p>
<pre><code>$ which psql // This tells you which PostgreSQL you are using when you run $ psql.
</code></pre>
<p>Then run:</p>
<pre><code>$ echo $PATH
</code></pre>
<p>The key thing to take into account is this:</p>
<p><strong>Ensure that the path entry for the copy of PostgreSQL you want to run COMES BEFORE the path to the OS X system's PostgreSQL.</strong></p>
<p>This is a core requirement which decides which PostgreSQL gets run and is what I'm told leads to most of these issues.</p>

Application context being loaded twice - Spring Boot
|
<p>I have a fairly simple setup. A maven project with 3 modules : core/webapp/model. I'm using Spring boot to gear up my application. In webapp, i have a simple class WebappConfig as follows:</p>
<pre><code>@Configuration
@EnableAutoConfiguration
@ComponentScan(excludeFilters = @ComponentScan.Filter(Configuration.class))
public class WebappConfig {
public static void main(String[] args) {
SpringApplication app = new SpringApplication(WebappConfig.class);
app.setAdditionalProfiles("dev");
app.run(args);
}
}
</code></pre>
<p>and few classes in core/model module. My container-application point is :</p>
<pre><code>public class AbcdXml extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(WebappConfig.class);
}
}
</code></pre>
<p>And no web.xml! My model's pom has following spring boot related dependency :</p>
<pre><code><dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
</code></pre>
<p>Core's pom.xml :</p>
<pre><code><dependency>
<groupId>org.springframework.boot</groupId>

<p>Now running WebappConfig via Run as -> Java application works perfectly but i need to deploy the project as a war on tomcat7. Webapp's packaging is war. There is no tomcat provided jar's in lib except tomcat-jdbc and tomcat-tuli jar(Shouldn't be an issue?).</p>
<p>When i deploy my abcd.war, applicationcontext is getting loaded twice and result in following error stracktrace :</p>

<p>There is no web.xml as i mentioned earlier.</p>
<p>Few interesting things that i can't figure out why :</p>
<ol>
<li>After exploding the war, tomcat somehow create a ROOT folder with default web.xml[Must be Spring boot misconfiguration. How can i correct it? Pointers please?]</li>
<li>Even if i return same 'application' SpringApplicationBuilder in AbcdXml.java, i am facing the same issue of applicationcontext being loaded twice.</li>
</ol>
<p>Thanks for your help!</p>
<p>EDIT 1:</p>
<p>Content of web.xml that is generated in ROOT folder :</p>
<pre><code><?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_5.xsd" version="2.5">

Angularjs: Displaying array of objects
|
<p>For the life of me I cannot extract and print out the data in my array. I've generated JSON in PHP and I've wired up Angularjs to retrieve this data. The Angularjs development tool within Chrome is telling me that I have a variable "user" that is an array of objects (see below) when I run the code. I made user a rootScope variable "$rootScope.user = data;" so I can get at it. I'm a newb so none of this is probably best practice.</p>
<pre><code>{
user : [{"user_id":"1","firstname":"John","lastname":"Doe","email":"john.doe@email.com","age":"29","height":"74.5","weight":"200","gender":"M","birthdate":"2013-12-31","username":"john.doe","hash":"$2a$10$MECYLWuu6AwRxzBF\/CUys.AuqVm7Lf4BYRGezeusvLe6wNTkU3FEy"}]
}
</code></pre>
<p>This is the <code>ng-repeat</code> I use on the same page that shows the above "user" is within its scope:</p>
<pre><code><ul id="biometrics" ng-repeat="info in user">
<li>Age: {{info.age}}</li>
</ul>
</code></pre>
<p>What am I doing wrong? Perhaps what am I NOT doing wrong. I'm new to Angularjs to say the least.</p>
<hr>
<p>I tried what was suggested but to no avail. I just want to try and clarify my code/situation just to be sure I didn't screw up. I think I may have been unclear as this is also my first time posting on StackOverflow.</p>
<p>This is literally what my login.php file returns: </p>
<blockquote>
<p>[{"user_id":"1","firstname":"John","lastname":"Doe","email":"john.doe@email.com","age":"29","height":"74.5","weight":"200","gender":"M","birthdate":"2013-12-31","photoURL":"john.doe.jpg","username":"john.doe","hash":"$2a$10$MECYLWuu6AwRxzBF/CUys.AuqVm7Lf4BYRGezeusvLe6wNTkU3FEy"}]</p>
</blockquote>
<p>This is my login controller:</p>
<pre><code>app.controller("LoginController", ['$scope', '$rootScope', '$http', '$location', function($scope, $rootScope, $http, $location) {
$scope.errorMessage = "Wrong password or username";
$scope.login = function() {
$http({
url: "./login.php",
method: "POST",
data: { cache: false, username: $scope.username, password: $scope.password },
headers : {'Content-Type':'application/x-www-form-urlencoded; charset=UTF-8'}
}).success(function(data, status, headers, config) {
$rootScope.user = data;
$location.path('/dashboard');
}).error(function(data, status, headers, config) {
$scope.statusMessage = status;
alert($scope.errorMessage);
});
}
}]);
</code></pre>
<p>This is in my view HTML:</p>
<pre><code><ul id="biometrics" ng-repeat="info in user">
<li>Age: {{info}}</li>
</ul>
</code></pre>
<p>I get nothing when I try this and I tried data.user and got nothing.</p>

Javascript object get code as string
|
<p>First off, I am sorry if this is a duplicate, but every time I googled for 'object' and 'code' I got tutorial pages.</p>
<p>I want to know if there is any easy way to get the code associated with an object. Something like</p>
<pre><code>function A(){
this.name = 'Kaiser Sauze';
}
a = new A();
console.log(a.displayCode());
//OUTPUT
"function A(){ this.name = 'Kaiser Sauze';}"
</code></pre>
<p>I want to be able to view the code, modify it and reload the function, all from within the browser. I wanted to know if there was some way to do this, or if I have to prime the pump by doing something like this:</p>
<pre><code>function A(){
this.name = 'Kaiser Sauze';
this.code = "function A(){ this.name = 'Kaiser Sauze';}"
}
</code></pre>
<p>then every time the user loads up the text editor to view <code>this.code</code> I connect the onchange to update <code>this.code</code>.</p>
<p>EDIT</p>
<p>turns out yankee suggested a simple solution to this</p>
<pre><code>function A(x){
this.x = x ;
}
console.log(A.toString());
//OUTPUT
"function A(x){
this.x = x ;
}"
</code></pre>
<p>but in my implementation the variable 'x' can be a function (actually a complicated object with variables, functions and sub objects which I mix in via a call to dojo.mixin), so what I really want is to know the code when instantiated, something like so</p>
<pre><code>function A(x){
this.x = x ;
}
var a = new A(function(){/*DO SOMETHING*/);
console.log(a.toString());
//OUTPUT
"var a = new A(function(){/*DO SOMETHING*/);"
</code></pre>
<p>but, as most of you already know, all that gets output is something like "Object". I have almost found a way around this, by putting the initialization in a function like so</p>
<pre><code>function A(x){
this.x = x ;
}
function _A(){
var a = new A(function(){/*DO SOMETHING*/);
}
console.log(_A.toString());
//OUTPUT
"function _A(){
var a = new A(function(){/*DO SOMETHING*/);
}"
</code></pre>
<p>but that is confusing, and then I have to go in and start parsing the string which I do not want to do.</p>
<p>EDIT: The reason I ask all of this is b/c I want to make code that is both dynamically executable and highly modular. I am dealing with the canvas. I want the user to be able to click on a, for example, rectangle, view its code, and modify and then load/execute it. I have a series of rules but basically I have a shape class and everything that defines that shape (color, transparency, fills, strokes...) has to get passed as a parameter to the object cosntructor, something like:</p>
<pre><code>rect = new Shape({color : 'rgba(0,0,0,1)' ,
x : 0 ,
y : 0 ,
w : 100 ,
h : 100 ,
draw : function() {ctx.fillStyle = this.color;
ctx.fillRect(this.x,this.y,this.w,this.h);
}
});
</code></pre>
<p>This way the code is automatically modular, I don't have to worry about the color being defined at the top of the page, and then the height being defined half way down the page, and so on. Now the only thing I need is to somehow, pass as a parameter, the entire above string representation of the initialization. I could wrap it in a function and call toString on that, like so</p>
<pre><code>function wrapper(){
rect = new Shape({color : 'rgba(0,0,0,1)' ,
x : 0 ,
y : 0 ,
w : 100 ,
h : 100 ,
draw : function() {ctx.fillStyle = this.color;
ctx.fillRect(this.x,this.y,this.w,this.h);
},
code : wrapper.toString()
});
}
</code></pre>
<p>but then there are two problems. 1) I have to manually remove the <code>function wrapper()</code> and trailing <code>}</code> as well as moving every line to the left by one tab. 2) there is no guarantee that a user will remember to include the wrapper function as it is totally unecessary for purposes of drawing. I am trying to think of a way where the wrapper would seem natural, but I can't think of any. But then again I haven't slept in over 30 hours.</p>

"Unexpected token in JSON at position 0" using JSON.parse in Node with valid JSON
|
<p>I've been tearing my hair out over this one for hours now.</p>
<p>I have a simple Node server that's making a call to an external API to get a (massive, like 4+ MB) bit of JSON. I'm using about as boilerplate a request as you can get, taken straight from the Node docs:</p>
<pre><code>const muniURL = `http://api.511.org/transit/vehiclemonitoring?api_key=${API_KEYS.API_KEY_511}&format=json&agency=sf-muni`;
http.get(muniURL, (res) => {
const statusCode = res.statusCode;
const contentType = res.headers['content-type'];
console.log('Status Code:', statusCode);
console.log('Content Type:', contentType);
let error;
if (statusCode !== 200) {
error = new Error(`Request Failed.\n` +
`Status Code: ${statusCode}`);
} else if (!/^application\/json/.test(contentType)) {
error = new Error(`Invalid content-type.\n` +
`Expected application/json but received ${contentType}`);
}
if (error) {
console.log(`Request error: ${error.message}`);
// consume response data to free up memory
res.resume();
return;
}
res.setEncoding('utf8');
let rawData = '';
res.on('data', (chunk) => rawData += chunk);
res.on('end', () => {
try {
const parsedData = JSON.parse(rawData);
console.log('parsedData:', parsedData);
} catch (e) {
console.log(`Caught error: ${e.message}`);
}
});
}).on('error', (e) => {
console.log(`Got error: ${e.message}`);
});
</code></pre>
<p>...and every single time, it hits the <code>catch</code> statement with:
<code>Caught error: Unexpected token in JSON at position 0</code>. (Note the two spaces between 'token' and 'in'.)</p>
<p>I've checked the JSON returned from both Chrome and Postman with two different web-based JSON validators, and it comes back as valid. While writing <code>rawData</code> to a file looks something like a buffer(?)...</p>
<pre><code>1fef bfbd 0800 0000 0000 0400 efbf bdef
bfbd efbf bd72 efbf bdc8 b62d efbf bd2b
0c3f 7547 1cef bfbd 00ef bfbd efbf bd0b
efbf bd5b 49ef bfbd 2def bfbd 6c6b efbf
bd5c 55ef bfbd efbf bd44 3fef bfbd 126c

bfbd 5d2f 7bef bfbd efbf bde5 aa81 745e
efbf bd65 efbf bd31 efbf bdef bfbd efbf
...
</code></pre>
<p>...<code>Buffer.isBuffer</code> comes back false.</p>
<p>Thus far I've tried <code>JSON.stringify</code>ing first, <code>toString</code>ing, converting to a <code>new Buffer</code> and then stringifying, <code>.trim</code>ing white space, and <code>replace</code>ing all sorts of escaped characters, all to no avail.</p>
<p>What am I missing here?</p>
<hr>
<p>EDIT: I realized that I was validating JSON fetched by Chrome and Postman, which apparently are doing some pre-processing of some sort. <code>curl</code>ing the URL yields a whole bunch of mess that's definitely not JSON. Still left with the questions of what data type that mess actually is, and why I'm not getting JSON when I'm specifically requesting it.</p>

How to compile C# DLL on the fly, Load, and Use
|
<p>A) compiling C# EXE's and DLL's on the fly are relatively easy.<br>
B) Executing an EXE means that a new application is run. Loading a DLL means that methods and functions can be used in cases that may be shared between applications or projects.<br>
<br>
Now, the quickest and easiest way to compile your EXE (or with mild modifications, DLL) can be found from the <a href="http://msdn.microsoft.com/en-us/library/saf5ce06%28v=vs.110%29.aspx" rel="nofollow">MSDN</a> or for your convenience:<br></p>
<pre><code>private bool CompileCSharpCode(string script)
{
lvErrors.Items.Clear();
try
{
CSharpCodeProvider provider = new CSharpCodeProvider();
// Build the parameters for source compilation.
CompilerParameters cp = new CompilerParameters
{
GenerateInMemory = false,
GenerateExecutable = false, // True = EXE, False = DLL
IncludeDebugInformation = true,
OutputAssembly = "eventHandler.dll", // Compilation name
};
// Add in our included libs.
cp.ReferencedAssemblies.Add("System.dll");
cp.ReferencedAssemblies.Add("System.Windows.Forms.dll");
cp.ReferencedAssemblies.Add("Microsoft.VisualBasic.dll");
// Invoke compilation. This works from a string, but you can also load from a file using FromFile()
CompilerResults cr = provider.CompileAssemblyFromSource(cp, script);
if (cr.Errors.Count > 0)
{
// Display compilation errors.
foreach (CompilerError ce in cr.Errors)
{
//I have a listview to display errors.
lvErrors.Items.Add(ce.ToString());
}
return false;
}
else
{
lvErrors.Items.Add("Compiled Successfully.");
}
provider.Dispose();
}
catch (Exception e)
{
// never really reached, but better safe than sorry?
lvErrors.Items.Add("SEVERE! "+e.Message + e.StackTrace.ToString());
return false;
}
return true;
}
</code></pre>
<p>Now that you can compile on the fly, there are a few variances between how to load the DLL. Typically speaking, you would add it as a reference in Visual Studios to be compiled into the project. This is rather easy and you have probably done it many times over, but we want to use it in our current project, and we can't very well require the user to recompile the entire project every time they want to test out their new DLL. Therefor, I will simply discuss how one loads a library 'on the fly'. Another term here would by "programmatically". To do this, after a successful compile, we load up an Assembly as follows:<br></p>
<pre><code>Assembly assembly = Assembly.LoadFrom("yourfilenamehere.dll");
</code></pre>
<p>If you have an AppDomain, you can try this:<br></p>
<pre><code>Assembly assembly = domain.Load(AssemblyName.GetAssemblyName("yourfilenamehere.dll"));
</code></pre>
<p><br>
Now that the lib is "referenced", we can open it up and use it. There are 2 ways to do this. One requires you to know if the method has parameters, another will check for you. I'll do the later, you can check the <a href="http://msdn.microsoft.com/en-us/library/25y1ya39.aspx" rel="nofollow">MSDN</a> for the other.<br></p>
<pre><code>// replace with your namespace.class
Type type = assembly.GetType("company.project");
if (type != null)
{
// replace with your function's name
MethodInfo method = type.GetMethod("method");
if (method != null)
{
object result = null;
ParameterInfo[] parameters = method.GetParameters();
object classInstance = Activator.CreateInstance(type, null);
if (parameters.Length == 0) // takes no parameters
{
// method A:
result = method.Invoke(classInstance, null);
// method B:
//result = type.InvokeMember("method", BindingFlags.InvokeMethod, null, classInstance, null);
}
else // takes 1+ parameters
{
object[] parametersArray = new object[] { }; // add parameters here
// method A:
result = method.Invoke(classInstance, parametersArray);
// method B:
//result = type.InvokeMember("method", BindingFlags.InvokeMethod, null, classInstance, parametersArray);
}
}
}
</code></pre>
<p>PROBLEM:
First compile works fine. First execution works fine. However, the recompile attempt will error, saying that your *.PDP (debugger database) is in use. I've heard some hints about marshaling, and AppDomains, but I haven't quite cleared up the problem. Recompile will only fail after the DLL has been loaded.</p>

MyBatis doesn't return all the results from the query
|
<h1>The Problem</h1>
<p>I have a query that returns 17 records. When I use MyBatis with a map that has an <code><association></code> it returns 6 records. <em>Note that this doesn't happen with my other maps, I have many other maps with associations that all work fine.</em></p>
<p><strong>Query:</strong></p>
<pre><code> with leave_counts as
(
select leave_type_id, count(llm.leave_id) as count
from lw_leave_master llm
group by leave_type_id
)
select llt.leave_type_id, llt.leave_type_abbr_tx,
llt.leave_type_desc_tx, lc.count as count_nm
from lw_leave_type llt
join leave_counts lc on lc.leave_type_id=llt.leave_type_id
order by llt.leave_type_abbr_tx
</code></pre>
<p><strong>Map:</strong></p>
<pre><code><resultMap id="typeCountMap" type="mypackage.myclass">
<result property="count" column="count_nm"/>
<association property="type" resultMap="package.myMap"/>
</resultMap>
<resultMap id="myMap" type="mypackage.myclass2">
<result property="id" column="leave_type_id"/>
<result property="abbr" column="leave_type_abbr_tx"/>
<result property="description" column="leave_type_desc_tx"/>
</resultMap>
</code></pre>
<p>The <code><association></code> in <code>typeCountMap</code> refers to the map <code>myMap</code>.</p>
<p>This returns 6 records every time. Grabbing the actual query run from the logger and running it manually returns 17 records.</p>
<h1>Solutions?</h1>
<p><strong>There are two things I can do to get MyBatis to return all 17 records</strong></p>
<p><strong>#1</strong></p>
<p>If I remove the <code>lc.count as count_nm</code> from my query I get all 17 records returned (just with no values associated with them)</p>
<pre><code> with leave_counts as
(
select leave_type_id, count(llm.leave_id) as count
from lw_leave_master llm
group by leave_type_id
)
select llt.leave_type_id, llt.leave_type_abbr_tx,
llt.leave_type_desc_tx
from lw_leave_type llt
join leave_counts lc on lc.leave_type_id=llt.leave_type_id
order by llt.leave_type_abbr_tx
</code></pre>
<p>This is obviously not a good solution, but I wanted to include this in case it would help you figure out what I'm doing wrong.</p>
<p><strong>#2</strong></p>
<p>If I replace the association with the contents of the other map everything works as expected.</p>
<pre><code><resultMap id="typeCountMap" type="mypackage.myclass1">
<result property="count" column="count_nm"/>
<result property="type.id" column="leave_type_id"/>
<result property="type.abbr" column="leave_type_abbr_tx"/>
<result property="type.description" column="leave_type_desc_tx"/>
</resultMap>
</code></pre>
<p>This obviously is what I'll do if I don't find another solution, since this does work. It would just be nice to use the <code><association></code> like I have in other maps.</p>
<p>I should note that I am using MyBatis 3.1.1</p>

How to gray out HTML form inputs?
|
<p>What is the best way to gray out text inputs on an HTML form? I need the inputs to be grayed out when a user checks a check box. Do I have to use JavaScript for this (not very familiar with JavaScript) or can I use PHP (which I am more familiar with)?</p>
<p><strong>EDIT:</strong></p>
<p>After some reading I have got a little bit of code, but it is giving me problems. For some reason I cannot get my script to work based on the state of the form input (enabled or disabled) or the state of my checkbox (checked or unchecked), but my script works fine when I base it on the values of the form inputs. I have written my code exactly like several examples online (mainly <a href="http://www.javascriptkit.com/javatutors/deform3.shtml" rel="nofollow noreferrer">this one</a>) but to no avail. None of the stuff that is commented out will work. What am I doing wrong here?</p>
<pre><code><label>Mailing address same as residental address</label>
<input name="checkbox" onclick="disable_enable()" type="checkbox" style="width:15px"/><br/><br/>
<script type="text/javascript">
function disable_enable(){
if (document.form.mail_street_address.value==1)
document.form.mail_street_address.value=0;
//document.form.mail_street_address.disabled=true;
//document.form.mail_city.disabled=true;
//document.form.mail_state.disabled=true;
//document.form.mail_zip.disabled=true;
else
document.form.mail_street_address.value=1;
//document.form.mail_street.disabled=false;
//document.form.mail_city.disabled=false;
//document.form.mail_state.disabled=false;
//document.form.mail_zip.disabled=false;
}
</script>
</code></pre>
<p><strong>EDIT:</strong></p>
<p>Here is some updated code based upon what @Chief17 suggested. Best I can tell none of this is working. I am using <code>value</code> as a test because it works for some reason</p>
<pre><code> <label>Mailing address same as residental address</label>
<input name="checkbox" onclick="disable_enable()" type="checkbox" style="width:15px"/><br/><br/>

Crash : terminate called after throwing an instance of 'std::system_error' what(): Resource deadlock avoided
|
<p>I have a simple client /server application the code of which is mentioned below.
Please run the server in one shell and the client in another shell in linux.
First start the server and then the client.
When the server is done with it's work, it crashes with following exception:</p>
<p><em>terminate called after throwing an instance of 'std::system_error'

<p>This happens from the line m_thread->join() from inside the function Service::HandleClient

Creating a custom Jasypt PropertySource in Springboot
|
<p>I'm using Spring Boot to create a simple web application which accesses a database. I'm taking advantage of the autoconfiguration functionality for the DataSource by setting up <code>spring.datasource.*</code> properties in <code>application.properties</code>. That all works brilliantly and was very quick - great work guys @ Spring! </p>
<p>My companys policy is that there should be no clear text passwords. Therefore I need to have the <code>sping.datasource.password</code> encrypted. After a bit of digging around I decided to create a <code>org.springframework.boot.env.PropertySourceLoader</code> implementation which creates a jasypt <code>org.jasypt.spring31.properties.EncryptablePropertiesPropertySource</code> as follows:</p>
<pre><code>public class EncryptedPropertySourceLoader implements PropertySourceLoader
{
private final StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();
public EncryptedPropertySourceLoader()
{
//TODO: this could be taken from an environment variable
this.encryptor.setPassword("password");
}
@Override
public String[] getFileExtensions()
{
return new String[]{"properties"};
}
@Override
public PropertySource<?> load(final String name, final Resource resource, final String profile) throws IOException
{
if (profile == null)
{
final Properties props = PropertiesLoaderUtils.loadProperties(resource);
if (!props.isEmpty())
{
return new EncryptablePropertiesPropertySource(name, props, this.encryptor);
}
}
return null;
}
}
</code></pre>
<p>I then packaged this in it's own jar with a <code>META-INF/spring.factories</code> file as follows:</p>
<pre><code>org.springframework.boot.env.PropertySourceLoader=com.mycompany.spring.boot.env.EncryptedPropertySourceLoader
</code></pre>
<p>This works perfectly when run from maven using <code>mvn spring-boot:run</code>. The problem occurs when I run it as a standalone war using <code>java -jar my-app.war</code>. The application still loads but fails when I try to connect to the database as the password value is still encrypted. Adding logging reveals that the <code>EncryptedPropertySourceLoader</code> is never loaded. </p>
<p>To me this sounds like a classpath issue. When run under maven the jar loading order is strict but once under the embebed tomcat there is nothing to say that my custom jar should be loaded before Spring Boot.</p>
<p>I've tried adding the following to my pom.xml to ensure the classpth is preserved but it doesn't seem to have had any effect.</p>
<pre><code><build>

<p>A step forward: I've managed to fix this by having the <code>EncryptedPropertySourceLoader</code> class implement <code>org.springframework.core.PriorityOrdered</code> interface and returning <code>HIGHEST_PRECEDENCE</code> from <code>getOrder()</code>. This has now fixed the issue of the PropertySourceLoader not being used. However it's now throwing the following error when it tries to decrypt the properties:</p>
<pre><code>org.jasypt.exceptions.EncryptionInitializationException: java.security.NoSuchAlgorithmException: PBEWithMD5AndDES SecretKeyFactory not available
at org.jasypt.encryption.pbe.StandardPBEByteEncryptor.initialize(StandardPBEByteEncryptor.java:716)

at org.springframework.boot.context.config.ConfigFileApplicationListener$ConfigurationPropertySources.getProperty(ConfigFileApplicationListener.java:490)
</code></pre>
<p>Again this doesn't happen when running from <code>mvn spring-boot:run</code> but does happen when running from the executable war file. Both scenarios use the same JVM (jdk1.6.0_35). Results on Google/Stackoverflow suggest this is an issue with the java security policy but as it does work when run from maven I think I can discount that. Possibly a packaging issue...</p>

How to forcefully set IE's Compatibility Mode off from the server-side?
|
<p>In a domain-controlled environment I'm finding that the compatibility mode is triggered on certain clients (winXP/Win7, IE8/IE9) even when we are providing a X-UA tags, a !DOCTYPE definition and "IE=Edge" response headers. These clients have the "display intranet sites in compatibility view" checkbox ticked. Which is precisely what I'm trying to override.</p>
<p>The following is the documentation that I've used to try understand how IE decides to actually trigger the compatibility mode.</p>
<p><a href="http://msdn.microsoft.com/en-us/library/ff406036%28v=VS.85%29.aspx" rel="noreferrer">http://msdn.microsoft.com/en-us/library/ff406036%28v=VS.85%29.aspx</a></p>
<p><a href="http://blogs.msdn.com/b/ie/archive/2009/02/16/just-the-facts-recap-of-compatibility-view.aspx" rel="noreferrer">http://blogs.msdn.com/b/ie/archive/2009/02/16/just-the-facts-recap-of-compatibility-view.aspx</a></p>
<blockquote>
<p><b>Site owners are <em>always</em> in control of their content.</b> Site owners can choose to use the X-UA-Compatible tag to be absolutely declarative about how they’d like their site to display and to map Standards mode pages to IE7 Standards. <em>Use of the X-UA-Compatible tag overrides Compatibility View on the client.</em></p>
</blockquote>
<p>Google for <strong>"Defining Document Compatibility"</strong>, sadly the SPAM engine doesn't let me post more than 2 urls.</p>
<p>This is an <code>ASP .NET</code> web app and includes the following definitions on the master page:</p>
<pre><code><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<head>
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
</head>
</code></pre>
<p>and <code>web.config</code></p>
<pre><code><system.webServer>
<httpProtocol>
<customHeaders>
<clear />
<add name="X-UA-Compatible" value="IE=Edge" />
</customHeaders>
</httpProtocol>
</system.webServer>
</code></pre>
<p>I've used Fiddler to check that the header is indeed being injected correctly.</p>
<p>My understanding is that with these settings I should be able override the "Display intranet sites in Compatibility View" browser setting. But depending on the client I've found that some of them will still trigger compatibility mode.
It also seems to be down to the machine level rather a policy group setting, since I obtain different results even when I use with the same set of credentials on different clients.</p>
<p>Disabling the Compatibility View Settings checkbox does the trick. But the actual purpose is to make sure that the app is rendered exactly the same way regardless of the client settings.</p>
<p>Any thoughts and what I could be possibly missing? Is it possible at all to force IE to always render the pages without triggering Compat mode? </p>
<p>thanks a million,</p>
<p>Jaume</p>
<p><strong>PS:</strong> the site is currently in development and is of course not in Microsoft's compatibility list, but I've also checked just in case.</p>

how to get row values when checkbox is checked in gridview
|
<p>before I asked this I did some checking around to make sure that this doesn't turn out to be a duplicate and ways to get the row values from a row that has a checkbox in its template field...but I can't seem to get it working...So far I have tried</p>
<pre><code>protected void Page_Load(object sender, EventArgs e)
{
Entities NW = new Entities();
var customers =
from c in NW.Customers
where (c.ContactName.StartsWith("Ma") || c.ContactName.StartsWith("An")
|| c.ContactName.StartsWith("T")
|| c.ContactName.StartsWith("V")
)
orderby c.ContactName ascending
select new
{
c.CustomerID,
c.ContactName,
c.CompanyName,
c.City
};
gv1.DataSource = customers.ToList();
gv1.DataBind();
}
protected void Button1_Click(object sender, EventArgs e)
{
foreach (GridViewRow row in gv1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
CheckBox chkRow = (row.Cells[0].FindControl("CB") as CheckBox);
if (chkRow.Checked)
{
Label1.Text = row.Cells[2].Text;
}
}
}
}
</code></pre>
<p>I have stepped through the button click event and when it gets to </p>
<blockquote>
<p>if (chkRow.Checked)</p>
</blockquote>
<p>its showing as null and skips over it..</p>
<p>my markup is </p>
<pre><code><asp:GridView ID="gv1" runat="server">
<HeaderStyle BackColor="SkyBlue" />
<AlternatingRowStyle BackColor="Yellow" />
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="CB" runat="server" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</code></pre>
<p>when I look at the source after I run, the checkboxes are all named differently than what I gave them the ID of "CB", attached is the pic of the source when its running</p>
<p><img src="https://i.stack.imgur.com/MaiWI.png" alt="Source when ran"></p>

NgIf not updating when variable changes
|
<p>Right, so i have a header component (navbar) which contains the following template:</p>
<pre><code><ng-template [ngIf] = "authService.isAuthenticated()">
<li>
<a routerLink="Landing" class="navbar-brand" (click)="Logout()"><span class="xvrfont">Logout</span><i class="fa fa-sign-in" aria-hidden="true"></i></a>
</li>
<li>
<a routerLink="Profile" class="navbar-brand"><span class="xvrfont">{{authService.getUsername()}}</span><i class="fa fa-user-circle" aria-hidden="true"></i></a>
</li>
</ng-template>
</code></pre>
<p>This part of the nav should be visible when the user is authenticated. to find out it checks via authService.</p>
<p>To check if a user is authenticated, the following code is ran on every route change:</p>
<pre><code>checkAuthenticated(){
if (localStorage.getItem('token') != null){ this.authenticated = true; }
else { this.authenticated = false; }
console.log(this.authenticated); // for Debugging.
}
</code></pre>
<p>The NgIf statement calls this method: </p>
<pre><code>public isAuthenticated(){
return this.authenticated;
}
</code></pre>
<p>According to the logs, 'authenticated' <strong>is</strong> changing between true and false correctly, but the Ngif isn't responding to the changes somehow.</p>
<p>the header component.ts looks like this: </p>
<pre><code>import { Component, OnInit, ViewEncapsulation } from '@angular/core';
import {AuthService} from "../auth/auth.service";
@Component({
selector: 'app-header',
providers: [AuthService],
templateUrl: './header.component.html',

encapsulation: ViewEncapsulation.None
})
export class HeaderComponent implements OnInit {
constructor(private authService: AuthService) { }
ngOnInit() {
}
Logout(){
this.authService.Logout();
}
}

Login form and Registration form without using database
|
<p>My Instructor gave me and my classmates some three activities and of those activities is to make a simple login form with a registration form without using database (well its obvious that we need to do this activity before proceeding with database).....</p>
<p>Here is the codes:
Form1:</p>
<pre><code> public partial class Form1 : Form
{
string Username;
string Password;
string NAME;
string Age;
Form2 Frm = new Form2();
//Here is where you get the value of the String from Form2
public void PassValue(string strValue)
{
Username = strValue;
}
public void PassAnotherValue(string strValue2)
{
Password = strValue2;
}
public void PassAnotherValueAgain(string strValue3)
{
NAME = strValue3;
}
public void PassAnotherValueAgainAndAgain(string strvalue4)
{
Age = strvalue4;
}
//------------------------------------------------------------------
public Form1()
{
InitializeComponent();
}
private void LoginBtn_Click(object sender, EventArgs e)
{
if (string.IsNullOrWhiteSpace(LoginUserNameTB.Text))
{
MessageBox.Show("Please input proper Username...!");
}
if (string.IsNullOrWhiteSpace(LoginPasswordTB.Text))
{
MessageBox.Show("Please input proper Password...!");
}
else if ((LoginUserNameTB.Text != Username) && (LoginPasswordTB.Text != Password))
{
MessageBox.Show("Welcome" + NAME + "!");
}
else if ((LoginUserNameTB.Text == Username) && (LoginPasswordTB.Text == Password))
{
MessageBox.Show("Please input proper Username and/or Password...!");
}
}
private void RegisterBtn1_Click(object sender, EventArgs e)
{
Frm.Show();
}
}
}
</code></pre>
<p>Form2:</p>
<pre><code>//Form2 has four textboxes, four labels, and a button
private void RegisterBtn2_Click(object sender, EventArgs e)
{
Form1 obj1 = new Form1();
Form1 obj2 = new Form1();
Form1 obj3 = new Form1();
Form1 obj4 = new Form1();
Form1 obj5 = new Form1();
//This is where you pass the String value back to Form1
obj1.PassValue(RegUserNameTB.Text);
obj2.PassAnotherValue(RegPasswordTB.Text);
obj3.PassAnotherValueAgain(NTB.Text);
obj4.PassAnotherValueAgainAndAgain(ATB.Text);
if (string.IsNullOrWhiteSpace(NTB.Text) && string.IsNullOrWhiteSpace(ATB.Text) && string.IsNullOrWhiteSpace(RegUserNameTB.Text) && string.IsNullOrWhiteSpace(RegPasswordTB.Text))
{
MessageBox.Show("Please enter the following:" + "\n" + "Name" + "\n" + "Age" + "\n" + "\n" + "UserName" + "\n" + "Password");
}
Close();
}
}
}
</code></pre>
<p>Now to the problem of this program.....
The program is working just fine and every time I enter a Username and a Password it worked but the value of the 'NAME' is missing and every time I clicked the Register Button it will only perform its action once and never again (probably needs an Exception).... And to sum it up our Instructor told us that the user will have a limit of 3 of entering its username and password and after that the program will close.... Any ideas?</p>

Angularjs simple datepicker using controller as not $scope
|
<p>I am trying to use the angular-ui bootstrap for dateranges.</p>
<p><a href="http://angular-ui.github.io/bootstrap/#/datepicker" rel="nofollow">http://angular-ui.github.io/bootstrap/#/datepicker</a> </p>
<p>The link contains some good examples. However I want to use <code>controller as</code> syntax and not the scope as it shows in the link above. </p>
<p>I have attempted it as seen below. But its not showing the calendar box when its clicked on. Its not returning any errors either so im a bit lost as to what I need to do. I think my example is close.</p>
<p>Here is my attempt on <a href="http://plnkr.co/edit/lANpSw?p=preview" rel="nofollow">fiddle</a></p>
<p>Code snippets below..</p>
<p><strong>js_file.js</strong></p>
<pre><code>angular.module('ui.bootstrap.demo', ['ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('DatepickerDemoCtrl', function() {
self = this;
self.someProp = 'Check This value displays.. confirms controller initalised'
self.opened = {};
self.open = function($event) {
$event.preventDefault();
$event.stopPropagation();
self.opened = {};
self.opened[$event.target.id] = true;
// log this to check if its setting the log
console.log(self.opened);
};
self.format = 'dd-MM-yyyy'
});

How to fix 'getter "documents" was called on null.' in flutter
|
<p>I am using flutter and firebase to create a mobile app. I have 2 collections on my firestore and i wanna read all documents in a the collection "posts". However, when I do that, an error saying the getter "documents" was called on null.</p>
<pre><code> Widget getContent(BuildContext context) {
return StreamBuilder<QuerySnapshot>(
stream: Firestore.instance.collection("posts").snapshots(),
builder: (context, snap) {
return CarouselSlider(
enlargeCenterPage: true,
height: MediaQuery.of(context).size.height,
items: getItems(context, snap.data.documents),
);
},
);
}
List<Widget> getItems(BuildContext context, List<DocumentSnapshot>
docs){
return docs.map(
(doc) {
String content = doc.data["content"];
return Text(content);
}
).toList();
}
</code></pre>
<p>I expected to be delivered with the data in all documents, nut instead got this error:</p>

<p>Few more points to consider:</p>
<ol>
<li><p>Earlier I was using <code>tomcat 5.3.5</code> but somebody told me that only tomcat 6 supports it so I downloaded <code>tomcat 6.0.35</code> and currently using this version only.</p></li>
<li><p>Configured <code>server.xml</code> and added the following code -</p>
<pre><code><Realm className="org.apache.catalina.realm.JNDIRealm"
debug="99"
connectionURL="ldap://server.domain.com:389/"
userPattern="{0}" />
</code></pre></li>
<li><p>Commented the following code from <code>server.xml</code> -</p>
<pre><code><!-- Commenting for LDAP
<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
resourceName="UserDatabase"/> -->
</code></pre></li>
<li><p>Steps 2 and 3 from <a href="http://viralpatel.net/blogs/implement-ldap-authentication-in-tomcat-jboss-server-for-java-app/" rel="noreferrer">article</a> </p></li>
<li><p>Someone suggested that there are some jar files that are supposed to be copied to tomcat in order to run <code>ldap</code> authentication, is that something I need to do? And which <code>jar</code> files?</p></li>
<li><p>Also, I am using the correct credentials for sure, then what is causing this issue?</p></li>
<li><p>Is there a way I can figure out the correct attributes for LDAP in case I am using incorrect ones?</p></li>

2-column TableLayout with 50% exactly for each column
|
<p>This one puzzles me since my first steps with Android. I can't make both columns in a 2-column TableLayout exact 50% each.</p>
<p>Here's an example:</p>
<pre><code><ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="fill_parent" >
<TableLayout
android:id="@+id/tablelayout"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:paddingRight="2dip" >
<TableRow>
<TextView
style="@style/TextViewStandard"
android_layout_span="2"
android:layout_weight="1"
android:text="Bla" />
</TableRow>
<TableRow>
<TextView
style="@style/TextViewStandard"
android:layout_weight="1"
android:text="Name:" />
<EditText
style="@style/EditTextStandard"
android:id="@+id/et_name"
android:layout_weight="1" />
</TableRow>
<TableRow>
<TextView
style="@style/TextViewStandard"
android:layout_weight="1"
android:text="URL:" />
<EditText
style="@style/EditTextStandard"
android:id="@+id/et_url"
android:layout_weight="1" />
</TableRow>
<TableRow>
<Button
style="@style/ButtonStandard"
android:layout_column="0"
android:layout_marginTop="6dip"
android:onClick="onClickOk"
android:text="@android:string/ok" />
</TableRow>
</TableLayout>
</ScrollView>
</code></pre>
<p>And here's the corresponding style definition:</p>
<pre><code><resources>
<style name="ButtonStandard" parent="@android:style/Widget.Button">
<item name="android:layout_height">wrap_content</item>
<item name="android:layout_width">fill_parent</item>
</style>
<style name="EditTextStandard" parent="@android:style/Widget.EditText">
<item name="android:layout_height">wrap_content</item>
<item name="android:layout_marginLeft">2dip</item>
<item name="android:layout_marginRight">2dip</item>
<item name="android:layout_marginTop">2dip</item>
<item name="android:layout_width">fill_parent</item>
</style>
<style name="TextViewStandard" parent="@android:style/Widget.TextView">
<item name="android:layout_height">wrap_content</item>
<item name="android:layout_marginLeft">2dip</item>
<item name="android:layout_marginRight">2dip</item>
<item name="android:layout_marginTop">2dip</item>
<item name="android:layout_width">fill_parent</item>
<item name="android:textColor">@android:color/white</item>
</style>
</resources>
</code></pre>
<p>This becomes really messed up with a CheckBox involved.</p>
<p>What's wrong with my definition?</p>
<p>Many thanks in advance.

Vuejs nested slots: how to pass slot to grandchild
|
<p>I use different vuetify components, for example <a href="https://vuetifyjs.com/en/components/menus" rel="noreferrer">v-menu</a>. It has a template like this:</p>
<pre><code><v-menu>
<a slot="activator">menu</a>
<v-list>
<v-list-tile>Menu Entry 1</v-list-tile>
<v-list-tile>Menu Entry 2</v-list-tile>
</v-list>
</v-menu>
</code></pre>
<p>Suppose I want to add another wrapper around it. That is my special menu component that has some predefined menu options. And I want it to has an activator slot as well. And the last should be somehow assigned to the original v-menu activator slot. Is it possible?</p>
<p>Example:</p>
<pre><code>// index.vue:
<template>
<my-special-menu>
<button>My special menu trigger</button>
</my-special-menu>
</template>
// MySpecialMenu.vue
<template>
<v-menu>
<slot slot="activator"/> <-- I don't know how to write this line
<v-list>...</v-list>
</v-menu>
</template>
</code></pre>
<p><code><slot slot="activator"></code> is an incorrect equation. The goal is to pull the content from the parent (that is <code><button>..</button></code> in the example), and use it as <code>slot="activator"</code> in v-menu.</p>
<p>I can write it like this:</p>
<pre><code><v-menu>
<a slot="activator"><slot/></a>
...
</v-menu>
</code></pre>
<p>But this case the result template will be:</p>
<pre><code><div class="v-menu__activator">
<a>
<button>My special menu trigger</button>
</a>
</div>
</code></pre>
<p>That's not exactly what I want. Is it possible to get rid off <code><a></code> wrapper here?</p>
<p>Update:
We can use a construction like <code><template slot="activator"><slot name="activator"/></template></code> to throw some slot to a grand child. But what if we have multiple slots and we want to proxy them all? That's like inheritAttrs and <code>v-bind="$attrs"</code> for slots. Is it currently possible?</p>
<p>For example, there's <code><v-autocomplete></code> component in vuetify that has append, prepend, label, no-data, progress, item, selection etc slots. I write some wrapper component around this, it currently looks like:</p>
<pre><code><template>
<v-autocomplete ..>
<template slot="append"><slot name="append"/></template>
<template slot="prepend"><slot name="prepend"/></template>
<template slot="label"><slot name="label"/></template>
...
<template slot="item" slot-scope="props"><slot name="item" v-bind="props"/></template>
</v-autocomplete>
</template>
</code></pre>
<p>Is it possible to avoid all slots enumeration here?</p>

<p>Here is the code for the Handsontable:</p>
<pre><code>$(document).ready(function() {
var data = [
["Dateiname", "Benutzer", "Erstelldatum", "Änderungsdatum", "Erste Zeile", "Kategorie", "Projekt"],
["Rechnung1.doc", "SB", "01.01.2010", "-", "Internetrechnung", "Rechnungen", "Haushalt"],
["Rechnung2.doc", "SB", "01.01.2012", "-", "Stromrechnung", "Rechnungen", "Haushalt"]
];
var container = $('#table');
container.handsontable({
data: data,
minSpareRows: 1,
rowHeaders: true,
colHeaders: true,
contextMenu: true
});
});
</code></pre>
<p>The scenario is as follows: </p>
<p>I've got a <code>.main-content</code> which takes up the whole window containing a Handsontable and a <code>.preview-content</code> which expands it width and shows content as soon as you click on the toggle button within the <code>.main-content</code>. The <code>.preview-content</code> is fixed and doesn't scroll with the <code>.main-content</code>.</p>
<p>The problem is that when the screen displaying the website is not big enough the <code>.preview-content</code> will cover parts of the Handsontable within the <code>.main-content</code>.
To prevent this from happening I wanted to change the width and height of the container containing the Handsontable dynamically so that I get scrollbars in case the table gets covered in parts.</p>
<p>I've tried many things so far but nothing seems to work. And it seems like Handsontable only likes absolute pixel dimensions for its width and height, otherwise <code>overflow: hidden</code> doesn't seem to work. </p>
<p>I've tried to change the width of the <code>.main-content</code> from 100% to 45% and added <code>overflow: auto</code> to the <code>.main-content</code> as you can see in the code, but that doesn't work as it behaves very strange.</p>
<p>Maybe someone has any idea how I can change the width of a Handsontable dynamically?</p>
<p>Your help is very appreciated. And if you need any more info to help me just say it I will see if I can provide the right info.</p>

SQL returns less results when using UNION?

<p>I have a SQL Server stored procedure that doesn't give me all the results when I add in the union and the second half. The first half will give me all 6 results, using the union, I only get 5. </p>
<p>There are 3 patients with their own [chart number], each have 2 items that should be displayed. if the [CPTCode] is the same for both entries of a patient, only one of the two entries show up when i add the union (it gives me all 6 with the same [cptcode] without the union). The second half isn't actually pulling any information with what i'm doing right now, but it is needed.</p>

Android: Java code output "NaN"
|
<p>So here I have this first time app I'm working on. When I run this code in the emulator for some reason I get a "NaN" output. The program essentially is meant to find the lowest price out of several choices (of quantity and price combined). I can't figure out what I'm doing wrong. Any advice?</p>
<p>(Note: The NaN output occurs only when NOT all of the EditText fields have a number in them)</p>
<p>main class:</p>
<pre><code>import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
import android.widget.EditText;
import android.widget.Button;
import android.view.View;

public class worthit extends Activity implements OnClickListener{
/** Called when the activity is first created. */
@Override

b.setOnClickListener(this);

//Declaring all of our variables that we will use in
//future calculations

EditText price2 = (EditText)this.findViewById(R.id.price2);

EditText quant1 = (EditText)this.findViewById(R.id.quant1);
EditText quant2 = (EditText)this.findViewById(R.id.quant2);
EditText quant3 = (EditText)this.findViewById(R.id.quant3);
EditText quant4 = (EditText)this.findViewById(R.id.quant4);
//TextView box used to present the results
TextView tv = (TextView)this.findViewById(R.id.result);
//Declaring two arrays of the values from
//all of our EditText fields

<p>Cheers.</p>
<p>EDIT: Apparently I also seem to be having a logic error somewhere. For example, if I choose the following prices: 1.4, 1.6, and I choose the following quantities (respectively) 18, 20, The output tells me that the $1.6 is the best choice; when you do the calculation by hand (1.4/18, 1/6,20) you get that 1.4 has the lowest ratio, thus it has to be the best choice. If anyone could tell me what I'm doing wrong that would be much appreciated.</p>
<p>Thank you.</p>

Adding space between columns of a TableLayout
|
<p>I have a TableLayout where I add dynamically TableRows. In each TableRow, I add a Button.</p>
<p>I just would like to add some space between my columns (which are my buttons) but I can't figure out how...
I've tried to change all the possible margins but it doesn't work :(
So maybe I made a mistake in my code where I inflate them from XML files:</p>
<pre><code>private void createButtons(final CategoryBean parentCategory) {
final List<CategoryBean> categoryList = parentCategory.getCategoryList();
title.setText(parentCategory.getTitle());
// TODO à revoir
int i = 0;
TableRow tr = null;
Set<TableRow> trList = new LinkedHashSet<TableRow>();
for (final CategoryBean category : categoryList) {
TextView button = (TextView) inflater.inflate(R.layout.button_table_row_category, null);
button.setText(category.getTitle());
if (i % 2 == 0) {
tr = (TableRow) inflater.inflate(R.layout.table_row_category, null);
tr.addView(button);
} else {
tr.addView(button);
}
trList.add(tr);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
CategoryBean firstChild = category.getCategoryList() != null && !category.getCategoryList().isEmpty() ? category
.getCategoryList().get(0) : null;
if (firstChild != null && firstChild instanceof QuestionsBean) {
Intent intent = new Intent(CategoryActivity.this, QuestionsActivity.class);
intent.putExtra(MainActivity.CATEGORY, category);
startActivityForResult(intent, VisiteActivity.QUESTION_LIST_RETURN_CODE);
} else {
Intent intent = new Intent(CategoryActivity.this, CategoryActivity.class);
intent.putExtra(MainActivity.CATEGORY, category);
startActivityForResult(intent, VisiteActivity.CATEGORY_RETURN_CODE);
}
}
});
i++;
}
for (TableRow tableRow : trList) {
categoryLaout.addView(tableRow);
}
}
</code></pre>
<p>My button_table_row_category.xml:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/buttonTableRowCategory"
style="@style/ButtonsTableRowCategory"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="@string/validate" />
</code></pre>
<p>My table_row_category.xml:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<TableRow xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tableRowCategory"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="100dp"
android:gravity="center"

</TableRow>

Change Matplotlib's default font
|
<p>I'm trying to change matplotlib's default font to Helvetica Neue. On my Mac with EPD/Canopy everything worked fine some time ago. </p>
<p>Trying to do the same on ubuntu now and it's not working. </p>
<p>This is what I did:</p>
<ol>
<li><p>Installed Helvetica Neue </p>
<pre><code>$ fc-match 'Helvetica Neue':Light
HelveticaNeue-Light.otf: "Helvetica Neue" "細體"
</code></pre></li>
<li><p>Converted the odt/dfont into ttf:</p>
<pre><code>fondu -show HelveticaNeue.dfont
</code></pre></li>
<li><p>changed matplotlibrc to </p>
<pre><code>$ cat ~/.config/matplotlib/matplotlibrc
...
font.family: Helvetica Neue
</code></pre>
<p>I also tried with:</p>
<pre><code>font.family: sans-serif
font.sans-serif: Helvetica Neue
</code></pre></li>
<li><p>I removed the font cache</p>
<pre><code>rm ~/.config/matplotlib/fontList.cache
</code></pre></li>
</ol>
<p>But none of these steps are working for me.</p>
<pre><code> $ python -c 'from matplotlib import pyplot as plt; plt.plot(1); plt.savefig("/tmp/test.png")'
/usr/local/lib/python2.7/dist-packages/matplotlib-1.3.0-py2.7-linux-x86_64.egg/matplotlib/font_manager.py:1236:
UserWarning: findfont: Font family ['Helvetica Neue'] not found. Falling back to Bitstream Vera Sans
</code></pre>
<p>(prop.get_family(), self.defaultFamily[fontext]))</p>
<p>Version is 1.3.0</p>
<pre><code> $ python -c 'import matplotlib; print matplotlib.__version__'
1.3.0
</code></pre>
<p>I also tried moving the fonts to <code>~/.config/matplotlib/fonts/ttf</code> but it didn't work. </p>
<hr>
<p><strong>EDIT:</strong>
As suggested I tried selecting a specific font for a specific text. </p>
<pre><code>import matplotlib as mpl
mpl.use('Agg')
import matplotlib.pyplot as plt
import matplotlib.font_manager as font_manager
path = '/home/<myusername>/.fonts/HelveticaNeue.ttf'
prop = font_manager.FontProperties(fname=path)
prop.set_weight = 'light'
mpl.rcParams['font.family'] = prop.get_name()
mpl.rcParams['font.weight'] = 'light'
fig, ax = plt.subplots()
ax.set_title('Text in a cool font', fontproperties=prop, size=40)
plt.savefig('/tmp/test2.png')
</code></pre>
<p>But it makes no difference.</p>
<pre><code>/usr/local/lib/python2.7/dist-packages/matplotlib-1.3.0-py2.7-linux-x86_64.egg/matplotlib/font_manager.py:1236:
UserWarning: findfont: Font family ['Helvetica Neue'] not found. Falling back to Bitstream Vera Sans
</code></pre>
<p>However I seem to experience this problem only with this Helvetica/Helvetica Neue font.
(prop.get_family(), self.defaultFamily[fontext]))</p>

Height of ListView fills the whole screen, although set as wrap_content
|
<p>i have this ListView inside a LinearLayout:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
.../>
<EditText />
...
</EditText>
<ListView
android:id="@+id/words_list"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
</LinearLayout>
</code></pre>
<p>The List is populated programmatically by a SimpleCursorAdapter:</p>
<pre><code>adapter = new SimpleCursorAdapter(this, R.layout.list_row_search, mCursor, from, to);
</code></pre>
<p>list_row_search has a TableLayout with two TableRows:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/TableLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<View
android:layout_height="1dip"
android:background="#FF33B5E5" />
<TableRow
android:id="@+id/tableRow1"
android:layout_height="wrap_content" >
<TextView
android:id="@+id/list_lesson"

android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="5.25"
android:padding="1dip"

android:textSize="18sp"
android:textStyle="bold" />
<TextView
android:id="@+id/list_flex"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="12.5"
android:padding="1dip"
android:paddingRight="10dp" />
<TextView
android:id="@+id/list_rom"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="6.25"
android:padding="1dip"
android:paddingRight="10dp" />
</TableRow>
<View
android:layout_height="0.1dip"
android:background="#404040" />
<TableRow
android:id="@+id/tableRow2"
android:layout_height="wrap_content" >
<TextView
android:id="@+id/list_related"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="2"
android:paddingRight="10dp"
android:textStyle="italic" />
<TextView
android:id="@+id/list_ant"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:paddingRight="10dp" />
<TextView
android:id="@+id/list_engl"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:paddingRight="10dp" />
</TableRow>
<View
android:layout_height="1dip"
android:background="#FF33B5E5" />
</TableLayout>
</code></pre>
<p>Now when the list gets populated, the ListView occupies the hole screen, even if only one element was found in the database. The HierarchyView in eclipse shows pretty clear, that the ListView is the one that fills out the screen.</p>
<p>Can you tell, where the problem is? Thanks for your time!</p>

Including .NET installer in WiX Bundle not detecting if already installed
|
<p>I'm on WiX 3.7, and I can't get the simple <PackageGroupRef Id="NetFx40Web"/> bundle element to work, as it doesn't bring across the Net FX installer package, or embed it in the setup.exe. I've resorted to creating my own package for this in my <code>Bundle.wxs</code> file, but I am still having trouble. It seems to always try to install .NET 4, even if the machine already has .NET installed.</p>
<p>I'm not quite sure of the difference between <em>InstallCondition</em> and <em>DetectCondition</em>. I think <em>InstallCondition</em> is used to install the package if the evaluation is true, otherwise uninstall it. How does this work with things that are typically <em>permanent=yes</em>, such as most pre-requisites? <em>DetectCondition</em> is almost the opposite, I think, in that it checks if it's already on the system, and if so, doesn't install it.</p>
<p>Below is my full <code>Bundle.wxs</code> file which is in a Visual Studio WiX Bootstrapper project. I'm attempting to look at the registry and scope out of .NET 4.0 registry key is there. If it is present, then I don't want to install .NET 4., and if it's not there, then install it. But, this isn't working, and it always attempts to install .NET.</p>

<p>I also checked the max_connections variable in the my.ini file in MySQL. Here's it's value:</p>
<blockquote>
<p>The maximum amount of concurrent sessions the MySQL server will
allow. One of these connections will be reserved for a user with
SUPER privileges to allow the administrator to login even if the
connection limit has been reached.
<code>max_connections=100</code></p>
</blockquote>
<p>The <em>show processlist</em> command on the MySQL terminal shows 101 processes in sleep. </p>
<p>Any kind of help/comments will be appreciated</p>
<p><strong>Update 2 -- Solution::</strong>
So, I figured out the solution. I hadn't mentioned the port name in the url connection to the database.</p>
<pre><code>String url = "jdbc:mysql://" + server_name + "/" + database;
</code></pre>
<p>Probably, hence it led to many <em>leaking</em> connections. Once done, I tried with the example given <a href="http://ezinearticles.com/?How-To-Create-A-Standalone-Connection-Pool-In-Java?&id=924710" rel="noreferrer">here</a>. It now doesn't throw any error. Thanks to BalusC, as I figured this out only due to his comment on changing the port number on MySQL. To add, the way to change the MySQL port number is <strong>NOT</strong> by changing the <em>my.ini</em> file but by running the <em>MySQL instance config wizard</em> under Start -> Programs -> MySQL Server 5.1 -> MySQL Server Instance Config Wizard. It was also interesting to note the code didn't throw any error when the port number wasn't specified and the program ran smoothly. Probably, JDBC connects to 3306 by default. If anyone has any particular idea about the same, please share.</p>

Chooser with camera intent and image picker intent
|
<p>I have created a chooser for either picking an image from file or for making a picture.</p>
<p>The code I use works fine on a Nexus 5, however when I try it on a Samsung S5, the chooser does not display the camera icons.</p>
<pre><code>public Intent makePhotoIntent(String title, Context ctx, String uniqueImageId){
//Build galleryIntent
Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
galleryIntent.setType("image/*");
//Create chooser
Intent chooser = Intent.createChooser(galleryIntent,title);
if (checkexCameraHardware()){
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
mTempImage = null;
try {
mTempImage = createImageFile(uniqueImageId);
} catch (IOException e) {
e.printStackTrace();
}
if (mTempImage != null){
cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, Uri.fromFile(mTempImage)); //add file ure (photo is saved here)
Intent[] extraIntents = {cameraIntent};
chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, extraIntents);
}
}
return chooser;
}
</code></pre>
<p><img src="https://i.stack.imgur.com/mZTaf.png" alt="Samsung"><img src="https://i.stack.imgur.com/5CS4x.png" alt="Nexus"></p>
<p>When I change the order in which the intents are added to the chooser the Samsung device does show the camera but only shows android-system as the file option.</p>
<pre><code>public Intent makePhotoIntent(String title, Context ctx, String uniqueImageId){
//Build galleryIntent
Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

if (mTempImage != null){
cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, Uri.fromFile(mTempImage)); //add file ure (photo is saved here)
//I have to re-create the chooser here or the Samsung will not show the 'camera' icons.
//I have to add the cameraIntent first.
chooser = Intent.createChooser(cameraIntent,title);

What exactly is join() in Boost::thread? (C++)
|
<p>In Java, I would do something like:</p>
<pre><code>Thread t = new MyThread();
t.start();
</code></pre>
<p>I start thread by calling start() method. So later I can do something like:</p>
<pre><code>for (int i = 0; i < limit; ++i)
{
Thread t = new MyThread();
t.start();
}
</code></pre>
<p>To create a group of threads and execute the code in run() method. </p>
<p>However, in C++, there's no such thing as start() method. Using Boost, if I want a thread to start running, I have to call the join() method in order to make a thread running. </p>
<pre><code>#include <iostream>
#include <boost/thread.hpp>
class Worker
{
public:
Worker()
{
// the thread is not-a-thread until we call start()
}
void start(int N)
{
m_Thread = boost::thread(&Worker::processQueue, this, N);
}
void join()
{
m_Thread.join();
}
void processQueue(unsigned N)
{
float ms = N * 1e3;
boost::posix_time::milliseconds workTime(ms);
std::cout << "Worker: started, will work for "
<< ms << "ms"
<< std::endl;
// We're busy, honest!
boost::this_thread::sleep(workTime);
std::cout << "Worker: completed" << std::endl;
}
private:
boost::thread m_Thread;
};
int main(int argc, char* argv[])
{
std::cout << "main: startup" << std::endl;
Worker worker, w2, w3, w5;
worker.start(3);
w2.start(3);
w3.start(3);
w5.start(3);
worker.join();
w2.join();
w3.join();
w5.join();
for (int i = 0; i < 100; ++i)
{
Worker w;
w.start(3);
w.join();
}
//std::cout << "main: waiting for thread" << std::endl;
std::cout << "main: done" << std::endl;
return 0;
}
</code></pre>
<p>On the code above, the for loop to create 100 threads, normally I must use a boost::thread_group to add the thread function, and finally run all with join_all(). However, I don't know how to do it with thread function putting in a class which uses various class members.</p>
<p>On the other hand, the loop above will not behave like the loop in Java. It will make each thread execute sequentially, not all at once like the other separated threads, whose own join() is called. </p>
<p>What is join() in Boost exactly? Also please help me to create a group of threads which share the same class.</p>

Angularjs: transclude directive template
|
<p>How to use transclusion in the below case. The intention is to use markup in the html (partials) file, than defining it in template (within the directive).</p>
<p>I found a great tree directive here. (<a href="https://groups.google.com/forum/#!msg/angular/vswXTes_FtM/kfT_CufjLjgJ">source</a>)
Original: <a href="http://jsfiddle.net/n8dPm/">http://jsfiddle.net/n8dPm/</a></p>
<p>Instead of defining the template in the directive, I was trying to use a transcluded content. I also updated Angular to 1.2.0.rc2.
Updated: <a href="http://jsfiddle.net/aZx7B/2/">http://jsfiddle.net/aZx7B/2/</a></p>
<p>got below error</p>
<blockquote>
<p>TypeError: Property '$transclude' of object [object Object] is not a
function</p>
</blockquote>
<p>code:</p>
<pre><code>module.directive("tree", function($compile) {
return {
restrict: "E",
transclude: true,
scope: {family: '='},
template:
'<ul>' +
'<li ng-transclude></li>' +
'<li ng-repeat="child in family.children">' +
'<tree family="child"></tree>' +
'</li>' +
'</ul>',
compile: function(tElement, tAttr) {
var contents = tElement.contents().remove();
var compiledContents;
return function(scope, iElement, iAttr) {
if(!compiledContents) {
compiledContents = $compile(contents);
}
compiledContents(scope, function(clone, scope) {

});
<div ng-app="myapp">
<div ng-controller="TreeCtrl">
<tree family="family">
<p>{{ family.name }}</p>

<h2>Edit:</h2>
<p>With David's suggestion, made some changes. <a href="http://jsfiddle.net/aZx7B/3/">http://jsfiddle.net/aZx7B/3/</a>
now, it prints, Parent. changing, <code>family</code> -> <code>treeFamily</code> didn't work though</p>

<p>and there are many more where those came from. I have tried using static libraries, but then it just delays the problem until the next executable I try to include these libraries into. I have also tried using g++ instead of c++. I've tried swapping around library orders. Also, it is not a template issue since at least one of the references it can't find is not a templated function. I have searched the libraries for the symbols, and I was able to find them, although they were prepended and postpended by random characters.</p>
<p>I don't understand what's going on. Please help.</p>
<p>Thanks,</p>
<p>UPDATE</p>
<p>I found another link, specifically <a href="https://stackoverflow.com/questions/6891447/cmake-variable-scope-add-subdirectory">this one</a>, that mentioned potential problems with add_subdirectory. This is a subproject to another project. So I sent into the project and built there. It worked! It still doesn't work in the parent directory though. Maybe that can give clues to someone. </p>
<p>Thanks again,</p>

android imageButton onClick method not calling
|
<p>EDIT: Posting full code (except XML as it a bunch of ridiculous table formatting!) Please ignore the code that doesn't pertain to my question! I am just getting functionality right now. I'll clean it up later.</p>
<p>First app and first question. I've researched here a while and usually find my answer but I have a bugger that is probably very obvious. I have an imageButton that doesn't seem to be calling the method assigned.</p>
<p>My XML for my imageButton:</p>
<pre><code><ImageButton
android:background="@null"
android:onClick="click"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/imageButton1"
android:src="@drawable/stats"
android:layout_gravity="center_vertical">
</ImageButton>
</code></pre>
<p>My code:</p>
<pre><code>package com.talismancs;
import android.app.Activity;
import android.content.Intent;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;
public class sheet extends Activity{
private String selection;
private String pick;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sheet);
Bundle extras = getIntent().getExtras();
if(extras !=null) {
// Get extra from .main and remove spaces
String pick = extras.getString(selection);
pick = pick.replace(" ", "");
//Convert extra from string to int as ID and make image
int imageResource = getResources().getIdentifier(pick, "drawable", getPackageName());
ImageView iv = (ImageView) findViewById(R.id.imageView1);
final Drawable image = getResources().getDrawable(imageResource);
iv.setImageDrawable(image);
// Populate tv's from string
TextView tv1 = (TextView) findViewById(R.id.textView4);
TextView tv2 = (TextView) findViewById(R.id.textView5);
TextView tv3 = (TextView) findViewById(R.id.textView6);
TextView tv4 = (TextView) findViewById(R.id.textView7);
TextView tv5 = (TextView) findViewById(R.id.textView8);
int arrayresource = getResources().getIdentifier(pick, "array", getPackageName());
String[] CharString = getResources().getStringArray(arrayresource);
tv1.setText(CharString[0]);
tv2.setText(CharString[1]);
tv3.setText(CharString[2]);
tv4.setText(CharString[3]);
tv5.setText(CharString[4]);
}
}
public void onClick(View view) {
Intent i = new Intent(sheet.this, stats.class);
i.putExtra(pick, pick);
startActivity(i);
}
</code></pre>
<p>}</p>
<p>Seems simple right? When I click the imageButton it does absolutely nothing!</p>
<p>Please help.</p>
<p>EDIT: LOGCAT After selecting a spinner item which gets us to this activity .sheet</p>

ASP.NET with OpenIdAuthentication: redirect to url if not authorized
|
<p>I am attempting to write an ASP.NET application that uses a hybrid authentication scheme.
A user can either have his username and password hash stored in the UserStore, or he can authenticate via Azure Active Directory.</p>
<p>I have created the login form pictured. It has the standard <code>UserName</code> and <code>Password</code> inputs, but also has a "Login via Active Directory" button.</p>
<p><a href="https://i.stack.imgur.com/pYc8C.png" rel="noreferrer"><img src="https://i.stack.imgur.com/pYc8C.png" alt="enter image description here"></a></p>
<p>This works well.</p>
<p>Now for the problem: The application's home page has the <code>[Authorize]</code> attribute. </p>
<pre><code>public class DefaultController : Controller
{
[Authorize]
public ViewResult Index()
{
// Implementation
}
}
</code></pre>
<p>If the user is not logged in, I want it to redirect to the page <code>Account/Login</code>, allowing the user to choose the authentication method.</p>
<p>Once I added <code>IAppBuilder.UseOpenIdConnectAuthentication</code> to the pipeline setup, it no longer redirects to that page. Instead, it goes straight to the Microsoft Login page.</p>
<p>How do I configure it so that OpenID authentication is part of the system, but allow me to specify how to perform redirections when the user is not authenticated?</p>
<p>Here's the code where I set up the pipeline:</p>
<pre><code>appBuilder.SetDefaultSignInAsAuthticationType(CookieAuthenticationDefaults.AuthenticationType_;
var cookieAuthenticationOptions = new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationType.ApplicationCookie,
LoginPath = new Microsoft.Owin.PathString("/Account/Login"),
Provider = new Security.CookieAuthenticationProvider()
};
appBuilder.UseCookieAuthentication(cookieAuthenticationOptions);
// Now the OpenId authentication
var notificationHandlers = new OpenIdConnectAuthenticationNotificationHandlers
{
AuthorizationCodeReceived = async(context) => {
var jwtSecurityToken = context.JwtSecurityToken;
// I've written a static method to convert the claims
// to a user
var user = await GetOrCreateUser(context.OwinContext, jwtSecurityToken.Claims);
var signInManager = context.OwinContext.Get<SignInManager>();
await signInManager.SignInAsync(user, true, false);
}
}
var openIdOptions = new OpenIdConnectAuthenticationOptions
{
ClientId = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx",
Authority = "https://login.microsoftonline.com/xxxxx.onmicrosoft.com",
PostLogoutRedirectUri = "https://localhost:52538/Account/Login",
Notifications = notifcationHandlers
}
appBuilder.UseOpenIdConnectAuthentication(openIdOptions);
</code></pre>
<p>When you click "Active Directory Signin", it posts to "Account/SignInWithOpenId"</p>
<pre><code>public ActionResult SignInWithOpenId()
{
// Send an OpenID Connect sign-in request.
if (!Request.IsAuthenticated)
{
var authenticationProperties = new AuthenticationProperties
{
RedirectUri = "/"
};
HttpContext.GetOwinContext().Authentication.Challenge
(
authenticationProperties,
OpenIdConnectAuthenticationDefaults.AuthenticationType
);
return new EmptyResult();
}
else
{
return RedirectToAction("Index", "Default");
}
}
</code></pre>

ASP.NET MVC4 FormCollection.GetValues not returning correct values
|
<p>I'm building a mobile webiste using ASP.NET MVC4.
One of the pages in my solution contains a table where all the rows in the table can be edited and saved in one batch. To do this I am using FormCollection in the Action in the Controller. This works as expected for most of the fields, exept one: item.IsPercent. This field is a boolean, and FormCollection.GetValues("item.IsPercent") returns twice the number of rows in the table and the list always alternates between true and false, no matter what the actual values are.</p>
<p>How can I collect the right value for the Percent checkboxes?</p>
<p><strong>An Example</strong></p>
<p><img src="https://i.stack.imgur.com/ZxPNc.png" alt="enter image description here"></p>
<p><strong>My View</strong></p>
<pre><code>@using (Html.BeginForm()) {
@Html.AntiForgeryToken()
@Html.ValidationSummary(true)
foreach (var group in Model.GroupBy(i => i.Exercise.Name)) {
<table>
<tr>
<th colspan="4">@Html.Label(group.Key)</th>
</tr>
<tr>
<td>Load</td>
<td>Percent</td>
<td> </td>
<td>Reps</td>
</tr>
@foreach (var item in group.OrderBy(i => i.Order))
{
@Html.HiddenFor(modelItem => item.Id)
<tr>
<td>
@Html.EditorFor(modelItem => item.Load)
@Html.ValidationMessageFor(modelItem => item.Load)
</td>
<td>
@Html.EditorFor(modelItem => item.IsPercent)
</td>
<td>
x
</td>
<td>
@Html.EditorFor(modelItem => item.Repetitions)
@Html.ValidationMessageFor(modelItem => item.Repetitions)
</td>
</tr>
}
</table>
<br />
}
<p>
<input type="submit" value="Save" />
</p>
}
</code></pre>
<p><strong>My Controller</strong></p>
<pre><code>[HttpPost]
public ActionResult EditProgramTemplateLines(FormCollection c)
{
int i = 0;
int ptId = 0;
if (ModelState.IsValid)
{
var ptIdArray = c.GetValues("item.id"); // [1,2,3,4]
var ptLoadArray = c.GetValues("item.Load"); // [50, 55, 60, 80]
var ptPercentArray = c.GetValues("item.IsPercent"); // [true, false, true, false, true, false, true, false]
var ptRepsArray = c.GetValues("item.Repetitions"); // [13, 10, 5, 2]
for (i = 0; i < ptIdArray.Count(); i++) {
var ptLine = factory.GetProgramTemplateLine(Convert.ToInt32(ptIdArray[i]));
if(ptId == 0)
ptId = ptLine.ProgramTemplateId;
ptLine.Load = ConvertToDouble(ptLoadArray[i]);
ptLine.IsPercent = Convert.ToBoolean(ptPercentArray[i]);
ptLine.Repetitions = ConvertToInt(ptRepsArray[i]);
factory.SetEntryAsModified(ptLine);
}
factory.SaveChanges();
return RedirectToAction("Details", new { id = ptId });
}
return View();
}
</code></pre>
<p><strong>Updated solution</strong>
Considering the link posted in comment below <a href="https://stackoverflow.com/questions/1714989/formcollection-for-a-checkbox">FormCollection for a checkbox</a> my solution is to loop throug the array like this:</p>
<pre><code>var percentId = 0;
for(i = 0;i<ptIdArray.Count();i++){
if(ptPercentArray[percentId] == true){
item.IsPercent = true;
percentId = percentId + 2;
}
else{
item.IsPercent = false;
percentId++;
}
}

MySQL Server shuts down frequently and won't start again now

How do I create and sign certificates with Python's pyOpenSSL?
|
<p>I would like to use python to create a CA certificate, and client certificates that I sign with it. I will be using these with OpenVPN. After several days of research, and trial and error, this is what I've come up with:</p>
<pre><code>#!/usr/bin/env python
import os
import sys
import random
from OpenSSL import crypto
###########
# CA Cert #
###########
ca_key = crypto.PKey()
ca_key.generate_key(crypto.TYPE_RSA, 2048)
ca_cert = crypto.X509()
ca_cert.set_version(2)
ca_cert.set_serial_number(random.randint(50000000,100000000))
ca_subj = ca_cert.get_subject()
ca_subj.commonName = "My CA"
ca_cert.add_extensions([
crypto.X509Extension("subjectKeyIdentifier", False, "hash", subject=ca_cert),
])
ca_cert.add_extensions([
crypto.X509Extension("authorityKeyIdentifier", False, "keyid:always", issuer=ca_cert),
])
ca_cert.add_extensions([
crypto.X509Extension("basicConstraints", False, "CA:TRUE"),
crypto.X509Extension("keyUsage", False, "keyCertSign, cRLSign"),
])
ca_cert.set_issuer(ca_subj)
ca_cert.set_pubkey(ca_key)
ca_cert.sign(ca_key, 'sha256')
ca_cert.gmtime_adj_notBefore(0)
ca_cert.gmtime_adj_notAfter(10*365*24*60*60)
# Save certificate
with open("ca.crt", "wt") as f:
f.write(crypto.dump_certificate(crypto.FILETYPE_PEM, ca_cert))
# Save private key
with open("ca.key", "wt") as f:
f.write(crypto.dump_privatekey(crypto.FILETYPE_PEM, ca_key))
###############
# Client Cert #
###############
client_key = crypto.PKey()
client_key.generate_key(crypto.TYPE_RSA, 2048)
client_cert = crypto.X509()
client_cert.set_version(2)
client_cert.set_serial_number(random.randint(50000000,100000000))
client_subj = client_cert.get_subject()
client_subj.commonName = "Client"
client_cert.add_extensions([
crypto.X509Extension("basicConstraints", False, "CA:FALSE"),
crypto.X509Extension("subjectKeyIdentifier", False, "hash", subject=client_cert),
])
client_cert.add_extensions([
crypto.X509Extension("authorityKeyIdentifier", False, "keyid:always", issuer=ca_cert),
crypto.X509Extension("extendedKeyUsage", False, "clientAuth"),
crypto.X509Extension("keyUsage", False, "digitalSignature"),
])
client_cert.set_issuer(ca_subj)
client_cert.set_pubkey(client_key)
client_cert.sign(ca_key, 'sha256')
client_cert.gmtime_adj_notBefore(0)
client_cert.gmtime_adj_notAfter(10*365*24*60*60)
# Save certificate
with open("client.crt", "wt") as f:
f.write(crypto.dump_certificate(crypto.FILETYPE_PEM, client_cert))
# Save private key
with open("client.key", "wt") as f:
f.write(crypto.dump_privatekey(crypto.FILETYPE_PEM, client_key))
</code></pre>
<p>This generates the certificates and private keys, but unfortunately, I must be doing something wrong because they do not verify:</p>
<pre><code>$ openssl verify -verbose -CAfile ca.crt client.crt
client.crt: CN = Client
error 7 at 0 depth lookup:certificate signature failure
139823049836448:error:04091068:rsa routines:INT_RSA_VERIFY:bad signature:rsa_sign.c:293:
139823049836448:error:0D0C5006:asn1 encoding routines:ASN1_item_verify:EVP lib:a_verify.c:241:
</code></pre>
<p>What am I doing wrong?</p>

Flutter - Trouble launching app for debug on macOS

<p>I've recently tried to migrate code from <code>main.dart</code> to the beginning of <code>home_page.dart</code> so as to steam line my application. Since doing this, my app now won't compile, I suspect as it doesn't know where to launch the application.</p>
<p>This is the error I'm receiving, <code>Set the 'program' value in your launch config (eg 'bin/main.dart') then launch again</code> <strong>(in VSCode)</strong> but since migrating the code I don't have <code>main.dart</code>, below is the last used version before deletion including the current version of <code>home_page.dart</code></p>

Simple tutorial example (lambda expression) doesn't run
|
<p>Finally decided to start a bit of experimentation on the new features of jdk8, namely the <a href="http://docs.oracle.com/javase/tutorial/java/javaOO/lambdaexpressions.html" rel="nofollow">lambda expressions following the tutorial</a>. For convenience, I stripped-down the example, see SSCCE below. </p>
<p>Typing out the predicate just runs fine, refactoring it to a lambda expression as suggested (and actually done) by Netbeans compiles (?) without errors, but doesn't run. The laconic console printout is </p>
<blockquote>
<p>Fehler: Hauptklasse simple.Simple konnte nicht gefunden oder geladen
werden</p>
</blockquote>
<p>("Error: main class couldn't be found or loaded")</p>
<p>Environment:</p>
<ul>
<li>jdk: jdk-8-ea-bin-b102-windows-i586-08_aug_2013.exe</li>
<li>Netbeans 7.4 beta, bundle from 14.7.2013. Not sure if that's the latest, couldn't download from the Netbeans site (got a "content encoding error" when clicking on its download link)</li>
</ul>
<p>BTW, thought of using Netbeans only because it already has support for jdk8 (if not netbeans, who else ;-) - the eclipse beta preview from efxclipse has a similar issue (compiling but not running the example). So being definitely out off my comfort zone, possibly some very stupid mistake on my part... ? </p>

MatPlotLib, datetimes, and TypeError: ufunc 'isfinite' not supported for the input types…
|
<p>Here is a tiny piece of code that produces a filled in region between two lines of a graph:</p>
<pre><code>import matplotlib.pyplot as plt
import numpy as np
x = np.arange(0.0, 2, 0.01)
y1 = np.sin(2 * np.pi * x)
y2 = 1.2 * np.sin(4 * np.pi * x)
fig, ax1 = plt.subplots(1, 1, sharex=True)
# Test support for masked arrays.
ax1.fill_between(x, 0, y1)
ax1.set_ylabel('between y1 and 0')
y2 = np.ma.masked_greater(y2, 1.0)
ax1.plot(x, y1, x, y2, color='black')
ax1.fill_between(
x, y1, y2, where=y2 >= y1,
facecolor='green',
interpolate=True)
ax1.fill_between(x, y1, y2, where=y2 <= y1, facecolor='red', interpolate=True)
ax1.set_title('Now regions with y2>1 are masked')
# Show the plot.
plt.show()
</code></pre>
<p>It looks like so:</p>
<p><a href="https://i.stack.imgur.com/mMF5im.png" rel="noreferrer"><img src="https://i.stack.imgur.com/mMF5im.png" alt="Plot generated by the code"></a></p>
<p>Now, changing the start so that <code>x</code> is now a collections of date times objects like so:</p>
<pre><code>import datetime
x1 = np.arange(0.0, 2, 0.01)
now = np.datetime64(datetime.datetime.now())
x = np.array([now - np.timedelta64(datetime.timedelta(seconds=i)) for i in range(200)])
y1 = np.sin(2 * np.pi * x1)
y2 = 1.2 * np.sin(4 * np.pi * x1)
</code></pre>
<p>yields:</p>
<pre><code>Traceback (most recent call last): File "fill_between_demo.py", line 21, in <module>

<p><em>Why is that happening and how to fix it?</em></p>
<p>Note that plotting the data (aka not using <code>fill*</code>) works just fine.</p>

free() invalid pointer
|
<p>I'm getting the familiar free(): invalid pointer error. In trying to debug, I ended up commenting out each free() in my code, one by one, <em>until there were none left</em> and I'm still getting this runtime error. Has anyone else run into a similar issue?</p>
<p>By the way - it's difficult for me to debug this using gdb, because the entire server doesn't actually crash when the error message is printed, just the particular forked process that was handling the single client.</p>
<p>Thank you.</p>
