Some part of your SQL statement is nested too deeply. Rewrite the query or break it up into smaller queries
|
<p>I have action in my controller which calls the following method :</p>
<pre><code>public IQueryable<AaaUserContactInfo> getcontactinfo(long[] id)
{
var organizationsiteids = from accountsitemapping in entities.AccountSiteMappings
where id.Any(accountid => accountsitemapping.ACCOUNTID == accountid)
select accountsitemapping.SITEID;
var usersdepts = from userdept in entities.UserDepartments
join deptdefinition in entities.DepartmentDefinitions on userdept.DEPTID equals deptdefinition.DEPTID
where organizationsiteids.Any(accountid => deptdefinition.SITEID == accountid)
select userdept;
var contactsinfos = from userdept in usersdepts
join contactinfo in entities.AaaUserContactInfoes on userdept.USERID equals contactinfo.USER_ID
select contactinfo;
return contactsinfos;
}
</code></pre>
<p>But when I run the application and I navigate to the action method the folowing error will be raised on the view level:-</p>

Angular scrollable div
|
<p>I want to create an Angular App which displays a JSON data structure in a design which is very similar to a chatbox. I've created a component for the "chatbox" </p>
<p>Example structure (also the only content in my chatbox.component.ts):</p>
<pre><code> test = [
{ "date":"1","sender":"x","answer":"hello"},
{ "date": "2", "sender": "y", "answer": "hello my friend" },
{ "date": "3", "sender": "z", "answer": "bye" }
];
</code></pre>
<p>Chatbox.component.html :</p>
<pre><code><div class="inboxContainer">
<tr *ngFor="let msg of test">
<div class="wrapper">
<div class="sender">Sender: {{msg.sender}}</div>
<div class="date">Date : {{msg.date}}</div>
</div>
<div class="answer">Message: {{msg.answer}}<br></div>
</tr>
</div>
<div class="newMessageContainer">
<mat-form-field>
<mat-label>New Message</mat-label>
<textarea matInput cdkTextareaAutosize #autosize="cdkTextareaAutosize" cdkAutosizeMinRows="1"
cdkAutosizeMaxRows="3"></textarea>
</mat-form-field>
</div>
<div class ="sendMessageContainer">
<button mat-button>
Send
</button>
</div>
</code></pre>
<p>Chatbox.component.css :</p>
<pre><code>.inboxContainer {
width: 40vw;
height: 60vh;
border: 1px solid black;
margin: auto;
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
}
.newMessageContainer {
margin: auto;
position: absolute;
top: 80vh;

border-left:none;
}
.answer {
width: 38.8vw;
height: 18vh;
}
</code></pre>
<p>The button itself can be ignored, its really just the way of displaying the structure. Right the messages get displayed like that :
<a href="https://i.stack.imgur.com/mfbqV.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/mfbqV.png" alt="Chat"></a>
Its not designed yet and its not really important right now. Im able to display 3 messages but if I try to display 4,5 or 6 messages it overflows though the border (the border is fixed and the size should stay like that).<br>
My question would be : How can I add a scrollbar to the div?</p>
<p>Heres also an example that shows how it looks when I try to display 4 messages :

Can I remove this permission? (It cause INSTALL_FAILED_DUPLICATE_PERMISSION in Android 5.0 device)
|
<p>My tester said that he couldn't install the app from Play Store to his Nexus 5 (Lollipop). He said he got this error</p>
<pre><code>Unknown error code during application install “-505”
</code></pre>
<p>I took his phone and try to install the app via adb, I got this error</p>
<pre><code>Failure [INSTALL_FAILED_DUPLICATE_PERMISSION
perm=com.example.gcm.permission.C2D_MESSAGE
pkg=com.mailchimp.alterego]
</code></pre>
<p>After some reading, I came across this writing from @Commonsware </p>
<p><a href="http://commonsware.com/blog/2014/08/04/custom-permission-vulnerability-l-developer-preview.html" rel="nofollow noreferrer">http://commonsware.com/blog/2014/08/04/custom-permission-vulnerability-l-developer-preview.html</a></p>
<p>It's clearly that both my app and Mailchimp app (which installed on my tester's phone) has duplicated permission, <strong>com.example.gcm.permission.C2D_MESSAGE</strong>. I then check my git log to see when did I add that line to my AndroidManifest and found that it was when I implement GCM. Back then, I followed this tutorial</p>
<p><a href="https://developer.android.com/google/gcm/client.html" rel="nofollow noreferrer">https://developer.android.com/google/gcm/client.html</a></p>
<p><img src="https://i.stack.imgur.com/0iyjF.png" alt="enter image description here"></p>
<p>I guess, both I and Mailchimp developer follow the same tutorial, added same permission and now both our app has duplicate permission. </p>
<p>So, I remove that permission from my AndroidManifest and now I'm able to install my app on my tester's phone. I test the GCM message by sending to package to GCM server from my php script and app still got GCM message as it was. </p>
<p>So, will there be other issue raised because of that missing permission and what is the point of having that permission anyway? (since without it, my app still got GCM message)</p>
<p>My concern is, if our app is using a plugin/library that required permission. We won't be able to install our app on Lollipop device if there is another installed app which using the same library, isn't it?</p>
<p><strong>-- NOTE --</strong></p>
<p>I already read this question, few people suggest the same thing to what I did, remove permission. But no one talking about what will happen after we do it or why do we have to add it.</p>
<p><a href="https://stackoverflow.com/questions/27043933/install-failed-duplicate-permission-c2d-message">INSTALL_FAILED_DUPLICATE_PERMISSION... C2D_MESSAGE</a></p>
<p><strong>-- EDIT 1 --</strong></p>
<p>I went back to the tutorial, the tutorial was right, it was my wrong implementation </p>
<p><img src="https://i.stack.imgur.com/vYnqS.png" alt="enter image description here"></p>
<p>I (and Mailchimp developer) should add permission with the name of our <strong>app package + ".permission.C2D_MESSAGE"</strong> instead of just copy and paste com.example.gcm.permission.C2D_MESSAGE</p>
<pre><code><permission android:name="com.mycompany.myappname.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
</code></pre>
<p>But, this raise another question to me, tutorial said that if we don't add this permission or the name doesn't match the pattern, app won't get the message.But I got the message when I test even when I remove this pemission... weird.</p>

Most common way of writing a HTML table with vertical headers?
|
<p>Hi all it's been a while since I've asked something, this is something that has been bothering me for a while, the question itself is in the title:</p>
<blockquote>
<p>What's your preferred way of writing HTML tables that have vertical headers?</p>
</blockquote>
<p>By vertical header I mean that the table has the header (<code><th></code>) tag on the left side (generally)</p>
<blockquote>
<p><strong>Header 1</strong> data data data<br>
<strong>Header 2</strong> data data data<br>
<strong>Header 3</strong> data data data</p>
</blockquote>
<p>They look like this, so far I've come up with two options</p>
<h2>First Option</h2>
<pre>
<code>
<table id="vertical-1">
<caption>First Way</caption>
<tr>
<th>Header 1</th>
<td>data</td><td>data</td><td>data</td>
</tr>
<tr>
<th>Header 2</th>
<td>data</td><td>data</td><td>data</td>
</tr>
<tr>
<th>Header 2</th>
<td>data</td><td>data</td><td>data</td>
</tr>
</table>
</code>
</pre>
<p>The main advantage of this way is that you have the headers right (actually left) next to the data it represents, what I don't like however is that the <code><thead></code>, <code><tbody></code> and <code><tfoot></code> tags are missing, and there's no way to include them without breaking the nicelly placed together elements, which lead me to the second option.</p>
<h2>Second Option</h2>
<pre>
<code>
<style type="text/css">
#vertical-2 thead,#vertical-2 tbody{
display:inline-block;
}
</style>
<table id="vertical-2">
<caption>Second Way</caption>
<thead>
<tr>
<th colspan="3">Header 1</th>
</tr>
<tr>
<th colspan="3">Header 2</th>
</tr>
<tr>
<th colspan="3">Header 3</th>
</tr>
</thead>
<tbody>
<tr>
<td>row 1</td>
<td>row 1</td>
<td>row 1</td>
</tr>
<tr>
<td>data</td>
<td>data</td>
<td>data</td>
</tr>
<tr>
<td>data</td>
<td>data</td>
<td>data</td>
</tr>
</tbody>
<tfoot>
<tr>
<td colspan="4">Footer</td>
</tr>
</tfoot>
</table>
</code>
</pre>
<p>The main advantage here is that you have a fully descriptive html table, the drawbacks are that proper representation needs a bit of CSS for the <code>tbody</code> and <code>thead</code> tags and that the relation between the headers and data isn't very clear as I had my doubts when creating the markup.</p>
<hr>
<p>So, both ways render the table how it should, here a pitcure:</p>
<p><img src="https://i.stack.imgur.com/s0YDr.png" alt="render"><br>
With the headers on the left or right side if you would prefer it, so, any suggestions, alternatives, browser issues?</p>

How to pre-load all deployed assemblies for an AppDomain
|
<p><strong>UPDATE:</strong> I now have a solution I'm much happier with that, whilst not solving all the problems I ask about, it does leave the way clear to do so. I've updated my own answer to reflect this.</p>
<p><em>Original Question</em></p>
<p>Given an App Domain, there are many different locations that Fusion (the .Net assembly loader) will probe for a given assembly. Obviously, we take this functionality for granted and, since the probing appears to be embedded within the .Net runtime (<code>Assembly._nLoad</code> internal method seems to be the entry-point when Reflect-Loading - and I assume that implicit loading is probably covered by the same underlying algorithm), as developers we don't seem to be able to gain access to those search paths.</p>
<p>My problem is that I have a component that does a lot of dynamic type resolution, and which needs to be able to ensure that all user-deployed assemblies for a given AppDomain are pre-loaded before it starts its work. Yes, it slows down startup - but the benefits we get from this component totally outweight this.</p>
<p>The basic loading algorithm I've already written is as follows. It deep-scans a set of folders for any .dll (.exes are being excluded <em>at the moment</em>), and uses Assembly.LoadFrom to load the dll if it's AssemblyName cannot be found in the set of assemblies already loaded into the AppDomain (this is implemented inefficiently, but it can be optimized later):</p>
<pre><code>void PreLoad(IEnumerable<string> paths)
{
foreach(path p in paths)
{
PreLoad(p);
}
}
void PreLoad(string p)
{
//all try/catch blocks are elided for brevity
string[] files = null;
files = Directory.GetFiles(p, "*.dll", SearchOption.AllDirectories);
AssemblyName a = null;
foreach (var s in files)
{
a = AssemblyName.GetAssemblyName(s);
if (!AppDomain.CurrentDomain.GetAssemblies().Any(
assembly => AssemblyName.ReferenceMatchesDefinition(
assembly.GetName(), a)))
Assembly.LoadFrom(s);
}
}
</code></pre>
<p>LoadFrom is used because I've found that using Load() can lead to duplicate assemblies being loaded by Fusion if, when it probes for it, it doesn't find one loaded from where it expects to find it.</p>
<p>So, with this in place, all I now have to do is to get a list in precedence order (highest to lowest) of the search paths that Fusion is going to be using when it searches for an assembly. Then I can simply iterate through them.</p>
<p>The GAC is irrelevant for this, and I'm not interested in any environment-driven fixed paths that Fusion might use - only those paths that can be gleaned from the AppDomain which contain assemblies expressly deployed for the app.</p>
<p>My first iteration of this simply used AppDomain.BaseDirectory. This works for services, form apps and console apps.</p>
<p>It doesn't work for an Asp.Net website, however, since there are at least two main locations - the AppDomain.DynamicDirectory (where Asp.Net places it's dynamically generated page classes and any assemblies that the Aspx page code references), and then the site's Bin folder - which can be discovered from the AppDomain.SetupInformation.PrivateBinPath property.</p>
<p>So I now have working code for the most basic types of apps now (Sql Server-hosted AppDomains are another story since the filesystem is virtualised) - but I came across an interesting issue a couple of days ago where this code simply doesn't work: the nUnit test runner.</p>
<p>This uses both Shadow Copying (so my algorithm would need to be discovering and loading them from the shadow-copy drop folder, not from the bin folder) and it sets up the PrivateBinPath as being relative to the base directory.</p>
<p>And of course there are loads of other hosting scenarios that I probably haven't considered; but which must be valid because otherwise Fusion would choke on loading the assemblies.</p>
<p>I want to stop feeling around and introducing hack upon hack to accommodate these new scenarios as they crop up - what I want is, given an AppDomain and its setup information, the ability to produce this list of Folders that I should scan in order to pick up all the DLLs that are going to be loaded; regardless of how the AppDomain is setup. If Fusion can see them as all the same, then so should my code.</p>
<p>Of course, I might have to alter the algorithm if .Net changes its internals - that's just a cross I'll have to bear. Equally, I'm happy to consider SQL Server and any other similar environments as edge-cases that remain unsupported for now.</p>
<p>Any ideas!?</p>

Pass multiple JSON objects to MVC3 action method
|
<p>JQuery code:</p>
<pre>
//This passes NULL for "CategoryID", "CategoryName", "ProductID", "ProductName"
$("#btnPost").click(function () {
var CategoryModel = {
CategoryID: 1,
CategoryName: "Beverage"
};
var ProductModel = {
ProductID: 1,
ProductName: "Chai"
};
var data1 = {};
data1["cat"] = CategoryModel;
data1["prd"] = ProductModel;
var jsonData = JSON.stringify(data1);
$.ajax({
url: url + '/Complex/ModelTwo', //This works but property values are null
type: 'post',
dataType: 'json',
data: { "cat": CategoryModel, "prd": ProductModel }, //jsonData,
cache: false,
success: function (result) {
alert(result);
},
error: function (xhr, ajaxOptions, thrownError) {
alert(thrownError);
}
});
});
</pre>
<p>MVC Code (C#):</p>
<pre><code> public class ComplexController : Controller
{
public string ModelOne(Category cat)
{
return "this took single model...";
}
public string ModelTwo(Category cat, Product prd)
{
return "this took multiple model...";
}
}
public class Category
{
public int CategoryID { get; set; }
public string CategoryName { get; set; }
}
public class Product
{
public int ProductID { get; set; }
public string ProductName { get; set; }
}
</code></pre>
<p>Now the issue is, I couldn't get it working by passing "CategoryMode", "ProductModel" into "ModelTwo" action method. The JQuery post correctly identifies the action method "ModelTwo" but "cat", "prd" property values are null. "CategoryID", "CategoryName", "ProductID", "ProductName" all are null despite hitting that method. </p>
<pre>
//THIS ONE WORKS FINE...
$("#btnPost").click(function () {
var CategoryModel = {
CategoryID: 1,
CategoryName: "Beverage"
};
var ProductModel = {
ProductID: 1,
ProductName: "Chai"
};
var data1 = {};
data1["cat"] = CategoryModel;
data1["prd"] = ProductModel;
var jsonData = JSON.stringify(data1);
$.ajax({
url: url + '/Complex/ModelOne', //This works
type: 'post',
dataType: 'json',
data: CategoryModel,
cache: false,
success: function (result) {
alert(result);
},
error: function (xhr, ajaxOptions, thrownError) {
alert(thrownError);
}
});
});
</pre>
<p>So what's wrong with my first JQuery call to "ModelTwo" action method?</p>
<p>I spent lots of time figuring this out, but not sure what's going on. There is no issue with routing here because I can land on the right action method...</p>
<p>Any help will be greatly appreciated.</p>
<p>Thanks!</p>

</code></pre>
<p>So basically, we can see that I only have one table on my MySQL database, it has four columns and one of them is 'role'.</p>
<p>But like what I said, when I use <code>request.isUserInRole("Service_Center")</code>, it returns FALSE. And <code>.antMatchers("/first").hasAuthority("Service_Center")</code> doesn't work either.</p>

How do I retrieve Google Finance Historical data in Google Sheets using the API?

<p>All is well so far. BUT, when I try to retrieve this data via the API (And I want to point out that all OTHER data is retrieved just fine), I get simple a "#N/A" for cell A1, and no values for all the other cells. It's like they're empty. I've tried retrieving just the values, but also all the gridinfo, both cases, it's like these values were never there.</p>
<p>Things I've tried:</p>
<ul>
<li>Setting a cell to "=TODAY()" before reading (some comments say that triggers a refresh of the data).</li>
<li>Looping with a delay trying to read the data, but that runs forever.</li>
<li>All this works flawlessly in the browser, but not over API calls</li>
<li>Other cells referencing this data fails with "#N/A"</li>
<li>If I add the add-on CryptoFinance, and insert this function "=CRYPTOFINANCE("COINMARKETCAP")", a range of cells are populated, similar to GoogleFinance. However, these cells CAN be retrieved via API calls. Works like a charm.</li>
<li><p>Any 'single' cell using googlefinance works fine, so if I add cell I1 shown below, THAT value is retrieved just fine</p>
<pre><code>=GoogleFinance("AMZN", "price")
</code></pre></li>
</ul>
<p>It just simply seems like the data is not there when using the HISTORICAL data from google finance (as per the API call).</p>
<p>I have not posted my code, since it seems this is more a case of googlefinance not working than anything else, and specifically when returning a 'range' of data instead of single cell values.</p>
<p>Thoughts?</p>

select2, ng-model and angular
|
<p>Using <a href="https://select2.github.io/" rel="nofollow">jquery-select2</a> (<strong>not</strong> ui-select) and angular, I'm trying to set the value to the ng-model.</p>
<p>I've tried using <code>$watch</code> and <code>ng-change</code>, but none seem to fire after selecting an item with select2.</p>
<p>Unfortunately, I am using a purchased template and cannot use angular-ui.</p>
<p><strong>HTML:</strong></p>
<pre><code><input type="hidden" class="form-control select2remote input-medium"
ng-model="contact.person.id"
value="{{ contact.person.id }}"
data-display-value="{{ contact.person.name }}"

data-remote-load-url="api_get_person"
ng-change="updatePerson(contact, contact.person)">
</code></pre>
<p><strong>ClientController:</strong></p>
<pre><code>$scope.updatePerson = function (contact, person) {
console.log('ng change');
console.log(contact);
console.log(person);
} // not firing
$scope.$watch("client", function () {
console.log($scope.client);
}, true); // not firing either
</code></pre>
<p><strong>JQuery integration:</strong></p>
<pre><code>var handleSelect2RemoteSelection = function () {
if ($().select2) {
var $elements = $('input[type=hidden].select2remote');
$elements.each(function(){

$this.select2({

}
});

</code></pre>
<p>Any advice would be greatly appreciated! :)</p>
<p><strong>UPDATE</strong></p>
<p>I've managed to put together <a href="http://plnkr.co/edit/Ca0fCKFPHjZCPh3OUMYg" rel="nofollow">a plunk</a> which seems to similarly reproduce the problem - it now appears as if the ng-watch and the $watch events are fired only when first changing the value.
Nevertheless, in my code (and when adding further complexity like dynamically adding and removing from the collection), it doesn't even seem to fire once.</p>
<p>Again, pointers in the right direction (or in any direction really) would be greatly appreciated!</p>

<p>From the error status 400 I know that the post JSON data is invalid. I suspect maybe in the structure because according to the documentation it should be like this:</p>
<pre><code>{
"paymentMethod": {
"type": "neteller",
"value": "gb_gbp@neteller.com"
},
"transaction": {
"merchantRefId": "20140203122501",
"amount": 5000,
"currency": "USD"
},
"verificationCode": "234124"
}
</code></pre>
<p>So how do I change the JSON parameter so that it could follow the structure in the documentation? </p>

Conversion from nested json to csv with pandas
|
<p>I am trying to convert a nested json into a csv file, but I am struggling with the logic needed for the structure of my file: it's a json with 2 objects and I would like to convert into csv only one of them, which is a list with nesting.</p>
<p>I've found very helpful "flattening" json info in <a href="https://towardsdatascience.com/flattening-json-objects-in-python-f5343c794b10" rel="nofollow noreferrer">this blog post</a>. I have been basically adapting it to my problem, but it is still not working for me.</p>
<p>My json file looks like this:</p>
<pre><code>{
"tickets":[
{
"Name": "Liam",
"Location": {
"City": "Los Angeles",
"State": "CA"
},
"hobbies": [
"Piano",
"Sports"
],
"year" : 1985,
"teamId" : "ATL",
"playerId" : "barkele01",
"salary" : 870000
},
{
"Name": "John",
"Location": {
"City": "Los Angeles",
"State": "CA"
},
"hobbies": [
"Music",
"Running"
],
"year" : 1985,
"teamId" : "ATL",
"playerId" : "bedrost01",
"salary" : 550000
}
],
"count": 2
}
</code></pre>
<p>my code, so far, looks like this:</p>
<pre class="lang-py prettyprint-override"><code>import json
from pandas.io.json import json_normalize
import argparse
def flatten_json(y):
out = {}
def flatten(x, name=''):
if type(x) is dict:
for a in x:
flatten(x[a], name + a + '_')
elif type(x) is list:
i = 0
for a in x:
flatten(a, name + str(i) + '_')
i += 1
else:
out[name[:-1]] = x
flatten(y)
return out
if __name__ == '__main__':
parser = argparse.ArgumentParser(description='Converting json files into csv for Tableau processing')
parser.add_argument(
"-j", "--json", dest="json_file", help="PATH/TO/json file to convert", metavar="FILE", required=True)
args = parser.parse_args()
with open(args.json_file, "r") as inputFile: # open json file
json_data = json.loads(inputFile.read()) # load json content
flat_json = flatten_json(json_data)
# normalizing flat json
final_data = json_normalize(flat_json)
with open(args.json_file.replace(".json", ".csv"), "w") as outputFile: # open csv file
# saving DataFrame to csv
final_data.to_csv(outputFile, encoding='utf8', index=False)
</code></pre>
<p>What I would like to obtain is 1 line per ticket in the csv, with headings:</p>
<p><code>Name,Location_City,Location_State,Hobbies_0,Hobbies_1,Year,TeamId,PlayerId,Salary</code>.</p>
<p>I would really appreciate anything that can do the click!
Thank you!</p>

Arithmetic calculation for BODMAS in Java
|
<p>I have written this code for Bodmas, but getting some error in this. If I do 3-5+9, it will result in 3.04.0.</p>
<p>It just start concatenating, though it works for all other operations like *, / and -, please help.</p>
<pre><code>public static String calculation(BODMASCalculation bodmas, String result) {
while (bodmas.hasMatch()) {
double value, leftOfOperator = bodmas.getLeft();
char op = bodmas.getOperator();
double rightOfOprator = bodmas.getRight();
switch (op) {
case '/':
if(rightOfOprator == 0) //Divide by 0 generates Infinity
value = 0;
else
value = leftOfOperator / rightOfOprator;
break;
case '*':
value = leftOfOperator * rightOfOprator;
break;
case '+':
value = leftOfOperator + rightOfOprator;
break;
case '-':
value = leftOfOperator - rightOfOprator;
break;
default:
throw new IllegalArgumentException("Unknown operator.");
}
result = result.substring(0, bodmas.getStart()) + value + result.substring(bodmas.getEnd());
bodmas = new BODMASCalculation(result);
}
return result;
}
</code></pre>
<p>Another function is:-</p>
<pre><code>public boolean getMatchFor(String text, char operator) {
String regex = "(-?[\\d\\.]+)(\\x)(-?[\\d\\.]+)";
java.util.regex.Matcher matcher = java.util.regex.Pattern.compile(regex.replace('x', operator)).matcher(text);
if (matcher.find()) {
this.leftOfOperator = Double.parseDouble(matcher.group(1));
this.op = matcher.group(2).charAt(0);
this.rightOfOprator = Double.parseDouble(matcher.group(3));
this.start = matcher.start();
this.end = matcher.end();
return true;
}
return false;
}
</code></pre>
<p>I have a solution by adding</p>
<pre><code>String sss = null;
if(op == '+' && !Str.isBlank(result.substring(0, bodmas.getStart())) && value >= 0)
sss = "+";
else
sss = "";
result = result.substring(0, bodmas.getStart()) + sss + value + result.substring(bodmas.getEnd());
</code></pre>
<p>But don't want to do that, I want this to work for all the operators.</p>

Keypress To Simulate A Button Click in C#
|
<p>Ok, so I'm in the process of making a Tic-Tac-Toe game to help me learn C#.
I'm attempting to add a bit of functionality to it, so I want people to be able to use the NumPad on a computer to simulate clicking the buttons.</p>
<p>Here is what I have but when I use the NumPad the buttons don't click.
Can any of you see a reason as to why?</p>
<pre><code> //===============================
// start NumPad Simulate Clicks
// NumPad MyButtons
// 7 8 9 1 2 3
// 4 5 6 4 5 6
// 1 2 3 7 8 9
//===============================
public void myControl_NumPad7(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == (char)Keys.NumPad7)
{
button1_Click(null, null);
}
}
public void myControl_NumPad8(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == (char)Keys.NumPad8)
{
button2_Click(null, null);
}
}
public void myControl_NumPad9(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == (char)Keys.NumPad9)
{
button3_Click(null, null);
}
}

{
if (e.KeyChar == (char)Keys.NumPad4)
{
button4_Click(null, null);
}

Angular 5: Returning an Observable from a function
|
<p>In the old days, I would define a new <code>Promise</code>, defer it, then resolve it when my function completed.
Now I find myself in a situation where I need to return an <code>Observable</code> from a function, and I want to be sure I'm setting it up properly in an <code>Angular 5</code> context.</p>
<p>Test function, working fine:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>getTreeViewChildren(currNode: any, nodeType: string, nodeTypeEnum: number = 0, nested: boolean = true)
: Observable<any>
{
let treeObs: Observable<any>;
treeObs = new Observable(obs => {
this.siteConfigService.getHostAccessPoints().subscribe(data => {
let hostAccessPoints = JSON.parse(data);
let accPointTree = this.findChildNodes(currNode, hostAccessPoints, nested);
obs.next(accPointTree);
obs.complete();
});
});
return treeObs;
}</code></pre>
</div>
</div>
</p>
<p>and from my NG component I successfully subscribe:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>this.configService.getTreeViewChildren(this.selectedTreeViewItem, type, nodetype, true).subscribe(tree =>{
let theTree = tree;
}); </code></pre>
</div>
</div>
</p>
<p>However the real function has much more retrieval logic. What is the correct way to setup the <code>Observable</code> as per my test function above? Same exact pattern, just wrapping all the code within <code>treeObs = new Observable(..)</code> ?</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>getTreeViewChildNodes(currNode: any, nodeType: string, nodeTypeEnum: number = 0, nested: boolean = true): Observable<any> {
let hosts;
let locations;
let hostAccessPoints;
let treeResult: Observable<any>;
if (nodeTypeEnum === NodeType.Location) {
// more code..
let someTree = getStuff();
return someTree;
}
if (nodeTypeEnum === NodeType.Host) {
// more code..
let someTree = getStuff();
return someTree;
}
if (nodeTypeEnum === NodeType.HostAccessPoint) {
let accPointTree;

let someTree = getStuff();
return someTree;

}
if (nodeTypeEnum === NodeType.HostStorage) {
// TO DO
}
}</code></pre>
</div>
</div>
</p>
<p>**** UPDATED (Based <code>Observable.of()</code> suggested answer below):</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>// Builds hierarchical treeview data

How do you add additional files to a wheel?
|
<p>How do control what files are included in a wheel? It appears <code>MANIFEST.in</code> isn't used by <code>python setup.py bdist_wheel</code>.</p>
<p><strong>UPDATE</strong>:</p>
<p>I was wrong about the difference between installing from a source tarball vs a wheel. The source distribution includes files specified in <code>MANIFEST.in</code>, but the installed package only has python files. Steps are needed to identify additional files that should be installed, whether the install is via source distribution, egg, or wheel. Namely, <a href="https://docs.python.org/2/distutils/setupscript.html#installing-package-data">package_data</a> is needed for additional package files, and <a href="https://docs.python.org/2/distutils/setupscript.html#installing-additional-files">data_files</a> for files outside your package like command line scripts or system config files.</p>
<h2>Original Question</h2>
<p>I have <a href="https://github.com/tulsawebdevs/django-multi-gtfs">a project</a> where I've been using <code>python setup.py sdist</code> to build my package, <code>MANIFEST.in</code> to control the files included and excluded, and <a href="https://pypi.python.org/pypi/pyroma">pyroma</a> and <a href="https://pypi.python.org/pypi/check-manifest">check-manifest</a> to confirm my settings.</p>
<p>I recently converted it to dual Python 2 / 3 code, and added a setup.cfg with</p>
<pre><code>[bdist_wheel]
universal = 1
</code></pre>
<p>I can build a wheel with <code>python setup.py bdist_wheel</code>, and it appears to be a universal wheel as desired. However, it doesn't include all of the files specified in <code>MANIFEST.in</code>. </p>
<h2>What gets installed?</h2>
<p>I dug deeper, and now know more about packaging and wheel. Here's what I learned:</p>
<p>I upload two package files to the <a href="https://pypi.python.org/pypi/multigtfs/0.4.2">multigtfs project on PyPi</a>:</p>
<ul>
<li><code>multigtfs-0.4.2.tar.gz</code> - the source tar ball, which includes all the files in <code>MANIFEST.in</code>.</li>
<li><code>multigtfs-0.4.2-py2.py3-none-any.whl</code> - The binary distribution in question.</li>
</ul>
<p>I created two new virtual environments, both with Python 2.7.5, and installed each package (<code>pip install multigtfs-0.4.2.tar.gz</code>). The two environments are almost identical. They have different <code>.pyc</code> files, which are the "compiled" Python files. There are log files which record the different paths on disk. The install from the source tar ball includes a folder <code>multigtfs-0.4.2-py27.egg-info</code>, detailing the installation, and the wheel install has a <code>multigtfs-0.4.2.dist-info</code> folder, with the details of that process. However, from the point of view of code using the multigtfs project, there is no difference between the two installation methods.</p>
<p>Explicitly, neither has the .zip files used by my test, so the test suite will fail:</p>
<pre><code>$ django-admin startproject demo
$ cd demo
$ pip install psycopg2 # DB driver for PostGIS project
$ createdb demo # Create PostgreSQL database
$ psql -d demo -c "CREATE EXTENSION postgis" # Make it a PostGIS database
$ vi demo/settings.py # Add multigtfs to INSTALLED_APPS,
# Update DATABASE to set ENGINE to django.contrib.gis.db.backends.postgis
# Update DATABASE to set NAME to test
$ ./manage.py test multigtfs.tests # Run the tests
...
IOError: [Errno 2] No such file or directory: u'/Users/john/.virtualenvs/test/lib/python2.7/site-packages/multigtfs/tests/fixtures/test3.zip'
</code></pre>
<h2>Specifying additional files</h2>
<p>Using the suggestions from the answers, I added some additional directives to <code>setup.py</code>:</p>
<pre><code>from __future__ import unicode_literals
# setup.py now requires some funky binary strings
...
setup(
name='multigtfs',
packages=find_packages(),
package_data={b'multigtfs': ['test/fixtures/*.zip']},
include_package_data=True,
...
)
</code></pre>
<p>This installs the zip files (as well as the README) to the folder, and tests now run correctly. Thanks for the suggestions!</p>

AES string encryption in Objective-C
|
<p>My Objective-C App requires text / string encryption (specifically <a href="/questions/tagged/nsstring" class="post-tag" title="show questions tagged 'nsstring'" rel="tag">nsstring</a>). </p>
<p>I know AES is the most secure encryption method available for consumer use. I also understand how to convert strings to data and back... (just a beginner). </p>
<p>Many webpages and Q/As about encryption with AES are unclear, and none of them state how to use the code given. For example, a webpage might say: "here is the code... here is what it does..." but no explanation for how to use it. </p>
<p>I've found this code through lots of research:</p>
<pre><code>#import "<CommonCrypto/CommonCryptor.h>"
@implementation NSMutableData(AES)
</code></pre>
<p>For encryption:</p>
<pre><code>- (NSMutableData*) EncryptAES:(NSString *)key {
char keyPtr[kCCKeySizeAES256+1];
bzero( keyPtr, sizeof(keyPtr) );
[key getCString: keyPtr maxLength: sizeof(keyPtr) encoding: NSUTF16StringEncoding];
size_t numBytesEncrypted = 0;
NSUInteger dataLength = [self length];
size_t bufferSize = dataLength + kCCBlockSizeAES128;
void *buffer = malloc(bufferSize);
NSMutableData *output = [[NSData alloc] init];
CCCryptorStatus result = CCCrypt(kCCEncrypt, kCCAlgorithmAES128, kCCOptionPKCS7Padding, keyPtr, kCCKeySizeAES256, NULL, [self mutableBytes], [self length], buffer, bufferSize, &numBytesEncrypted);
output = [NSMutableData dataWithBytesNoCopy:buffer length:numBytesEncrypted];
if(result == kCCSuccess) {
return output;
}
return NULL;
}
</code></pre>
<p>For Decryption:</p>
<pre><code>- (NSMutableData*)DecryptAES: (NSString*)key andForData:(NSMutableData*)objEncryptedData {
char keyPtr[kCCKeySizeAES256+1];
bzero( keyPtr, sizeof(keyPtr) );
[key getCString:keyPtr maxLength:sizeof(keyPtr) encoding:NSUTF16StringEncoding];
size_t numBytesEncrypted = 0;
NSUInteger dataLength = [self length];
size_t bufferSize = dataLength + kCCBlockSizeAES128;
void *buffer_decrypt = malloc(bufferSize);
NSMutableData *output_decrypt = [[NSData alloc] init];
CCCryptorStatus result = CCCrypt(kCCDecrypt , kCCAlgorithmAES128, kCCOptionPKCS7Padding, keyPtr, kCCKeySizeAES256, NULL, [self mutableBytes], [self length], buffer_decrypt, bufferSize, &numBytesEncrypted);
output_decrypt = [NSMutableData dataWithBytesNoCopy:buffer_decrypt length:numBytesEncrypted];
if(result == kCCSuccess) {
return output_decrypt;
}
return NULL;
}
}
</code></pre>
<p>This is the code I made that I would like to correspond with the above code:</p>
<pre><code>- (void)Encrypt {
//Convert NSString to NSData so that it can be used to encrypt the Input
NSString *Input = [Inputbox text];
NSData *InputData = [Input dataUsingEncoding:NSUTF8StringEncoding];
//What to do here
}
</code></pre>
<p>How do I use this code, these methods? Where does it go in my Implementation file?</p>

Reading JSON Tiled map editor file and displaying to canvas
|
<p>Im following this <a href="http://blog.hashrocket.com/posts/using-tiled-and-canvas-to-render-game-screens" rel="noreferrer">this</a> tutorial to be able to load json map files created by tiled map editor in my javascript/canvas game.</p>
<p>ive got to the point where i have implemented my own kind of version, and am getting no errors in firebug in console or net etc.</p>
<p>And as far as i can see, by putting in console.logs and alerts, the script is running absolutely fine!</p>
<p>The problem is the canvas stays blank! when it should have a tilemap now on it.</p>
<p>Here is my version of the tutorial implemented in my game:</p>
<pre><code>function Level() {
var c;
var data;
var layers = [];
this.get_map = function(name,ctx){
c = ctx;
$.getJSON('maps/'+ name + '.json', function(json){
get_tileset(json);
});
};
function get_tileset(json) {
data = json;
this.tileset = $("<img />", { src: json.tilesets[0].image })[0];
this.tileset.onload = renderLayers(this);
}
function renderLayers(layers){
layers = $.isArray(layers) ? layers : data.layers;
layers.forEach(renderLayer);
}
function renderLayer (layer){
if (layer.type !== "tilelayer" || !layer.opacity) {
alert("Not a tileLayer");
}
var s = c.canvas.cloneNode(),
size = data.tileWidth;
s = s.getContext("2d");
if (layers.length < data.layers.length) {
layer.data.forEach(function(tile_idx, i) {
if (!tile_idx) { return; }
var img_x, img_y, s_x, s_y,
tile = data.tilesets[0];
tile_idx--;
img_x = (tile_idx % (tile.imagewidth / size)) * size;
img_y = ~~(tile_idx / (tile.imagewidth / size)) * size;
s_x = (i % layer.width) * size;
s_y = ~~(i / layer.width) * size;
s.drawImage(this.tileset, img_x, img_y, size, size,
s_x, s_y, size, size);
});
layers.push(s.canvas.toDataURL());
c.drawImage(s.canvas, 0, 0);
}
else {
layers.forEach(function(src) {
var i = $("<img />", { src: src })[0];
c.drawImage(i, 0, 0);
});
}
}
}
</code></pre>
<p>and it is called from my main javascript file which is this:</p>
<pre><code>$(document).ready(function(){
var canvas = document.getElementById("TBG");
var ctx = canvas.getContext("2d");
var ui = new Gui();
var level = new Level();
//----------Login/Register Gui --------------
$('#TBG').hide();
$('#load-new').hide();
$('#reg').hide();
$('#login').hide();
//if login_but is clicked do ui.login function
$('#login_but').click(ui.login);
//if reg_but is clicked do ui.register function
$('#reg_but').click(ui.register);
$('#new_but').click(function(){
game_settings("new");
});
$('#load_but').click(function(){
game_settings("load");
});
//if login_sumbit button is clicked do ui.login_ajax function
$("#login_submit").click(ui.login_ajax);
$("#reg_submit").click(ui.register_ajax);
$("#welcome").on("click", "#logout_but", ui.logout);
//________________________
//Initialisation of game
function game_settings(state){
if(state == "load"){
ui.load_game();
//do ajax call to load user last save
level.get_map("level_01",ctx);
}
else{
//set beginning params
//Change screens
ui.new_game();
alert("new game");
}
}
// End Loop ------------------------------------------------------
});
</code></pre>
<p>I don't suppose you lovely people could spot why the tile-map isn't being printed to my canvas?</p>
<p>Thanks for any help Tom</p>

MySQLi export table to CSV
|
<p>I've been trying for many days to export from a query some values in <code>.csv</code> with MySQLi, but I have a problem when the export is made, everything is exporting to a single column, instead I need that the export should make like SQL code (I have 3 selected columns and I need 3 exported columns in <code>.cvs</code>).
Bellow you can find two codes:</p>
<p>1) This code creates a data base, table and insert the values:</p>
<pre><code><?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
// Create database
$sql = "CREATE DATABASE myDB";
if ($conn->query($sql) === TRUE) {
echo "Database created successfully";
} else {
echo "Error creating database: " . $conn->error;
}
// Create connection pt a crea tabela
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
// sql to create table
$sql = "CREATE TABLE MyGuests (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
firstname VARCHAR(30) NOT NULL,
lastname VARCHAR(30) NOT NULL,
email VARCHAR(50),
reg_date TIMESTAMP
)";
if ($conn->query($sql) === TRUE) {
echo "Table MyGuests created successfully";
} else {
echo "Error creating table: " . $conn->error;
}
// Create connection pt a insera valori
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
// Insert value in db
$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe, Mark', 'john@example.com'),
('Mary', 'Moe-Johny', 'mary@example.com'),
('Julie', 'Dooley', 'julie@example.com')";
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
</code></pre>
<p>2) This code is for the export in <code>.csv</code>:</p>
<pre><code><?php
//header to give the order to the browser
header('Content-Type: text/csv');
header('Content-Disposition: attachment;filename=export.csv');
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "myDB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT id, firstname, lastname FROM MyGuests";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "id: " . $row["id"]. " - Name: " . $row["firstname"]. " " . $row["lastname"]. "<br>";
}
} else {
echo "0 results";
}
$conn->close();
?>
</code></pre>
<p>I'm using this XAMP version:</p>
<blockquote>
<p>Apache/2.4.18 (Win32) OpenSSL/1.0.2e PHP/7.0.1</p>
<p>Database client version: libmysql - mysqlnd 5.0.12-dev - 20150407 - $Id: 7e72f9690b1498a1bead7a637c33a831c0d2f655 $</p>
<p>PHP extension: mysqli Documentation</p>
<p>PHP version: 7.0.1</p>
</blockquote>
<p>This version creates some problems for the MySQL code, that's why I prefer the code in MySQLi.
Thank you very much!</p>

How do I get a reference to an IHostedService via Dependency Injection in ASP.NET Core?
|
<h1>Details</h1>
<p>I have attempted to create a background processing structure using the recommended <code>IHostedService</code> interface in ASP.NET 2.1. I register the services as follows:</p>
<pre><code>services.AddSingleton<AbstractProcessQueue<AbstractImportProcess>>();
services.AddHostedService<AbstractBackgroundProcessService<AbstractImportProcess>>();
services.AddSignalR();
</code></pre>
<p>The <code>AbstractProcessQueue</code> is just a wrapper around a <code>BlockingCollection</code> of processes that can be enqueued and dequeued. The <code>AbstractBackgroundProcessService</code> implements the <code>IHostedService</code> interface and looks at the queue for new processes it can start.</p>
<p>Now, the trouble starts when, inside a <code>SignalR</code> hub, I attempt to get a reference to the background processing service via the <code>Dependency Injection</code> mechanisms. I have tried the following solutions, but none seem to be working as intended:</p>
<h3>Option 1:</h3>
<pre><code>public HubImportClient(IServiceProvider provider)
{
//This returns null.
var service = provider.GetService<AbstractBackgroundProcessService<AbstractImportProcess>>();
}
</code></pre>
<h3>Option 2:</h3>
<pre><code>public HubImportClient(IServiceProvider provider)
{
//This returns null.
var service = (AbstractBackgroundProcessService<AbstractImportProcess>) provider.GetService(typeof(AbstractBackgroundProcessService<AbstractImportProcess>>));
}
</code></pre>
<h3>Option 3:</h3>
<pre><code>public HubImportClient(IServiceProvider provider)
{
//This throws an exception, because the service is missing.
var service = provider.GetRequiredService<AbstractBackgroundProcessService<AbstractImportProcess>>();
}
</code></pre>
<h3>Option 4:</h3>
<pre><code>public HubImportClient(IServiceProvider provider)
{
//This throws an exception, because the service is missing.
var service = (AbstractBackgroundProcessService<AbstractImportProcess>) provider.GetRequiredService(typeof(AbstractBackgroundProcessService<AbstractImportProcess>);
}
</code></pre>
<h3>Option 5:</h3>
<pre><code>public HubImportClient(IServiceProvider provider)
{
//This returns a correct service, but prevents me from adding additional AbstractBackgroundProcessService implementations with different type parameters.
//Additionally, it seems like this reference was newly created, and not the instance that was created on application startup (i.e. the hash codes are different, and the constructor is called an additional time).
var service = provider.GetService<IHostedService>();
if(service is AbstractBackgroundProcessService<AbstractProcessService>)
{ this.Service = (AbstractBackgroundProcessService<AbstractProcessService>) service;}
}
</code></pre>
<h3>Option 6:</h3>
<pre><code>public HubImportClient(IServiceProvider provider)
{
//This works similarly to the previous option, and allows multiple implementations, but the constructor is still called twice and the instances thus differ.
AbstractBackgroundProcessService<AbstractImportProcess> service = null;
foreach(IHostedService service in provider.GetServices<IHostedService>())
{
if(service is AbstractBackgroundProcessService<AbstractImportProcess>)
{
service = (AbstractBackgroundProcessService<AbstractImportProcess>) service;
break;
}
}
}
</code></pre>
<h3>Option 7:</h3>
<pre><code>public HubImportClient(IServiceProvider provider)
{
//This just skips the for each loop all together, because no such services could be found.
AbstractBackgroundProcessService<AbstractImportProcess> service = null;
foreach(AbstractBackgroundProcessService<AbstractImportProcess> current in provider.GetServices<AbstractBackgroundProcessService<AbstractImportProcess> >())
{
service = current;
break;
}
}
</code></pre>
<h3>Option 8:</h3>
<pre><code>//This works, but prevents multiple implementations again.
public HubImportClient(IHostedService service)
{
this.Service = service;
}
</code></pre>
<h3>Option 9:</h3>
<pre><code>//This does not work again.
public HubImportClient(AbstractBackgroundProcessService<AbstractImportProcess> service)
{
this.Service = service;
}
</code></pre>
<h1>Question</h1>
<p>So then my question remains: how am I supposed to get a reference to an <code>IHostedService</code> implementation so that:</p>
<p>(a): I can inject multiple instances of the service that differ only by their type parameter (e.g. a hosted service for <code>AbstractImportProcess</code>es as well as one for <code>AbstractExportProcess</code>es)</p>
<p>(b): there is only ever one instance of the <code>IHostedService</code> for that specific type parameter.</p>
<p>Thanks in advance for any help!</p>

How to implement the classic "sticky footer" with angular-material?
|
<p>I recognize that the <a href="https://github.com/angular/material">Angular Material</a> implementation is a work in progress, but I've spent some time this morning trying to get familiar with it. However, I'm really struggling to get the concepts shown in the demos to work in a stand alone site.</p>
<p>It seems that when the directives like <code><md-toolbar></code> and <code><md-content></code> are used in containers with fixed heights, then they work great. I'm struggling with how to throw them inside a <code><body</code> tag and be able to have a sticky footer layout <a href="https://philipwalton.github.io/solved-by-flexbox/demos/sticky-footer/">like in this example</a>.</p>
<p>I've tried many variations, but here's one example that doesn't work when the content is removed from the DOM. When the content is there it grows beyond the viewport and the footer is placed afterwards like you'd expect. In the latest versions of Chrome and Firefox this example keeps the footer at the bottom when the content is removed, but in IE this just doesn't work at all. In IE the footer floats just below the header regardless of whether the main content is shown or not.</p>
<p><strong>DEMO:</strong> <a href="http://codepen.io/sstorie/pen/xbGgqb">http://codepen.io/sstorie/pen/xbGgqb</a></p>
<pre><code><body ng-app="materialApp" layou-fill layout='column'>
<div ng-controller="AppCtrl" layout='column' flex>
<md-toolbar class='md-medium-tall'>
<div class="md-toolbar-tools">
<span>Fixed to Top</span>
<span flex></span>
<md-button class="md-raised" ng-click="toggleContent(!displayContent)">toggle content</md-button>
</div>
</md-toolbar>
<main class='md-padding' layout="row" flex>
<div flex>
<md-card ng-if="displayContent" ng-repeat = "card in cards">
{{$index}}
{{card.title}}
{{card.text}}
</md-card>
</div>
<div flex>
<md-card ng-if="displayContent" ng-repeat = "card in cards">
{{$index}}
{{card.title}}
{{card.text}}
</md-card>
</div>
</main>
<md-toolbar class="md-medium-tall">
<div layout="row" layout-align="center center" flex>
<span>FOOTER</span>
</div>
</md-toolbar>
</div>
</body>
</code></pre>
<p>Javascript:</p>
<pre><code>angular.module('materialApp', ['ngMaterial'])
.controller('AppCtrl', function($scope) {
$scope.cards = [
{text: 'Bla bla bla bla bla bla bla ',
title: 'Bla' },
...repeat 10 times...
];
$scope.displayContent = true;
$scope.toggleContent = function(showContent) { $scope.displayContent = showContent; };
});
</code></pre>
<p>CSS:</p>
<pre><code>body {
min-height: 100%;
height: auto !important;
height: 100%;
}
</code></pre>
<p>I'm definitely not a CSS guru, but it feels like this should be easy to do with the layout options in angular-material, so I'm hoping I'm really missing something obvious here.</p>

The model item passed into the dictionary is of type ‘mvc.Models.ModelA’ but this dictionary requires a model item of type ‘mvc.Models.ModelB‘

<p>I have this annoying mistake in some of my builds.</p>
<p>There is no error in the project, because if I build again, then the problem disappears. The message only appears, when the site is deployed to a Windows 2008 Server.</p>
<p>I first thought that it might be an issue with temporary files, but thats not the case. I deployed the build to a different web and the error still appears.</p>
<p>The error appears on random actions of the site. Most of the time builds are ok, but each 3rd or 4th build produces runtime errors.</p>
<p>I build using a WebdeploymentProject in release mode. Views are precompiled.</p>

<p><strong>EDIT</strong></p>
<p>After some months this problem disapeared. I haven't had problems for over 1 year now. I guess the issue will strike again when nobody expects it.</p>
<p><strong>EDIT 2</strong></p>
<p>… for over 2 years now. I am such a lucky dude!</p>
<p><strong>EDIT 3</strong></p>
<p>I just read <a href="https://devblogs.microsoft.com/aspnet/enabling-the-net-compiler-platform-roslyn-in-asp-net-applications/" rel="nofollow noreferrer">an article on MSDN</a>, and it sounds like the problem I had. I have debugging disabled, but still the compilation was "sometimes wrong". The behaviour of the old provider could be the issue. But this is just guessing.</p>
<blockquote>
<p>Very large pages containing long spans of HTML with no server blocks (e.g. <%= %>) can cause a stack overflow when debug compilation is enabled that will crash the application. Note that in our testing it’s taken a page that’s ~4x as large one that would’ve produced a similar issue in the old provider, but in this case it crashes the entire application, whereas with the old provider it just fails the offending page</p>

Swagger declaration schema = @Schema(implementation = Map.class) represents Schema as String in swagger-ui
|
<p>I am trying to create <code>springdoc</code> swagger documentation, and I would like to represent a request body having data type <code>Map<String, Object></code> in a better readable way for clients. But when I declare <code>@io.swagger.v3.oas.annotations.parameters.RequestBody(content = @Content(schema = @Schema(implementation = Map.class)</code> the Schema is coming as <code>String</code>(attached the screenshot below)</p>
<p><a href="https://i.stack.imgur.com/8BY0G.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8BY0G.png" alt="enter image description here" /></a></p>
<p><strong>Method declaration</strong></p>
<pre><code> @Operation(security = {@SecurityRequirement(name = "bearer-key")}, summary = "Create Data", operationId = "createData", description = "Create createData for the **`type`**. ")
@ApiResponses(value = {
@ApiResponse(responseCode = "201", description = "Data created", content = @Content(schema = @Schema(implementation = Map.class),
examples = {@ExampleObject(value = "{\n" +
" \"id\": \"927d810c-3ac5-4584-ba58-7c11befabf54\",\n" +
"}")})),
@ApiResponse(responseCode = "400", description = "BAD Request")})
@PostMapping(value = "/data/type", produces = APPLICATION_JSON_VALUE, consumes = APPLICATION_JSON_VALUE)
@io.swagger.v3.oas.annotations.parameters.RequestBody(content = @Content(schema = @Schema(implementation = Map.class),
examples = {@ExampleObject(value = "{\n" +
" \"label\":\"tourism\",\n" +
" \"location\":\"France\"\n" +
" }")}))
ResponseEntity<Map<String, Object>> createData(@Parameter(name = "type", required = true) @PathVariable("type") String type, @Parameter(name = "request payload") @Valid @RequestBody Map<String, Object> body);
</code></pre>
<p>Though the Spring boot automatically infers the type based on the method signature, it is not clear for the data type <code>Map</code>. For instance, by default, the type Map<String, Object> will be inferred as below
<a href="https://i.stack.imgur.com/4MJf1.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/4MJf1.png" alt="enter image description here" /></a></p>
<p>But I would like to show the Schema in a more understandable way for the client who refers to my API. I could see there is a closed ticket without a proper solution in <a href="https://github.com/swagger-api/swagger-core/issues/3439" rel="nofollow noreferrer">Github</a>. As per my requirement, the request body should be a type agnostic and dynamic key-value pairs, so there is no other way apart from receiving the request as <code>Map<String, Object></code>. has anyone implemented a better way with type <code>Map</code> rather than creating a custom request/response model?</p>

Angular mat-paginator page size not working correctly
|
<p>I have created a mat-paginator element for a mat-table. My issue is that the paginator is not correctly displaying the page size. It will display all the results on one page, despite the page size being 5.Here I am making a request to an API to get a list of transactions, then adding them to a list to be displayed in the table. I have tried all the possible solutions I have found with no success.</p>
<pre><code>export class txns implements OnInit {
ELEMENT_DATA: ISalesOrders[] = [];
displayedColumns = ['type', 'source', 'amount'];
panelOpenState: boolean = false;
expandedElement: any;
dataSource = new MatExpandTableDataSource(this.ELEMENT_DATA);
config:any; //App Configuration
errorLoading:boolean = false;
doneLoading:boolean = false;
@ViewChild('paginator') paginator: MatPaginator;//Creates horizontal link with paginator
isExpansionDetailRow = (i: number, row: Object) =>
row.hasOwnProperty('detailRow');//Determines whether the the row is expandable.
/**
* Similar to constructor, NgINIT will wait until components dependencies are loaded.
*/
ngOnInit() {
this.getMonthlySalesTransactions(3).subscribe(data => {
console.log(data);
data.forEach((data) => {
if(data.result === 0) {
let results = data.objs as ISalesOrders[];
results.forEach(elem => {
this.ELEMENT_DATA.push(elem);
});
} else {
this.errorLoading = false;
}
this.doneLoading = true;
});
this.dataSource = new MatExpandTableDataSource(this.ELEMENT_DATA);
this.dataSource.paginator = this.paginator;
});
}

<p>but I only want 5 elements per page. any help is appreciated</p>
<p>i also want to have the ability to expand rows on click, so I created MatExpandTableDataSource class to let me do this. I believe this is were the problem is happening. If I switch to use MatTableDataSource it works, but it does not work properly when using this class.</p>

Javascript Sockets (failed: Error during WebSocket handshake: net::ERR_CONNECTION_RESET)
|
<p>I am trying to create a simple program to send a message to a socket in plain text. The sender is a webpage in javascript using websocket and the server is a C program. I don't have any control over the C code but I have been assured by the codes owners that I can use simple javascript to send the message. My code is as follows:</p>
<pre><code><!DOCTYPE HTML>
<html>
<head>
<script type="text/javascript">
//initialize the websocket ws
var ws;
//Open the socket connection
function openSock() {

<p>When I click the connect button I get this error:</p>
<blockquote>
<p>WebSocket connection to 'ws://192.168.6.222:11000/echo' failed: Error during WebSocket handshake: net::ERR_CONNECTION_RESET</p>
</blockquote>
<p>I have checked the firewall and the port seems to be open. After spending a fair amount of time troubleshooting the server (making sure it is running and on the network, etc.) I am wondering if I did something wrong with this client side code. </p>
<p>From my limited knowledge and the reading I have done this looks correct but any help is welcome.</p>

Vagrant: PHP7.0-fpm.service failed because the control process exited with error code
|
<p>I have a new ubuntu/xenial64 box based Vagrant installation. Unfortunately the PHP7.0 service does not running</p>
<p>If I running the following <code>systemctl status php7.0-fpm.service</code> command this will be the result:</p>
<pre><code>ubuntu@Project-Yii-Shop:~$ systemctl status php7.0-fpm.service

</code></pre>
<p>The main problem that I tried to enable this service but the Vagrant Ubuntu ask for password and well, this Ubuntu in the Vagrant does not have any password. I googled on this problem but I saw this solution only and the above one.</p>
<pre><code>ubuntu@Project-Yii-Shop:~$ systemctl enable php-fpm.service
==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-unit-files ===
Authentication is required to manage system service or unit files.
Authenticating as: Ubuntu (ubuntu)
Password:
polkit-agent-helper-1: pam_authenticate failed: Authentication failure
==== AUTHENTICATION FAILED ===
Failed to execute operation: Access denied
</code></pre>
<p>So I do not know what I should do, because if I install PHP7.0 on a real Ubuntu server (not in Vagrant) I do not get this error.</p>
<p>I use NGINX server with the following config:</p>
<pre><code>location ~ \.php$ {
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
#fastcgi_pass 127.0.0.1:9000;
fastcgi_pass unix:/var/run/php7.0-fpm.sock;
try_files $uri =404;
}
</code></pre>
<p>I use this command in the Vagrant file to install PHP7.0</p>
<pre><code>apt-get install -y git nginx php7.0-curl php7.0-cli php7.0-intl php7.0-mbstring php7.0-gd php-imagick php7.0-fpm php7.0-mysql php7.0-pgsql php7.0-xml php7.0-zip
</code></pre>
<p>And this command run after the Vagrant is up in order to run php7.0 srevice.</p>
<pre><code>service php7.0-fpm restart
</code></pre>
<p>Does anybody see any mistake?</p>

<p>The code I use for this is:</p>
<pre><code>DropBase drop = DropDB.getRandomDrop();
for (int i = 1; i < drop.getDrops().size() -1; i++) {
EntityItem item = new EntityItem(worldIn, pos.getX(), pos.getY() + 1, pos.getZ(), drop.getDrops().get(i));

worldIn.spawnEntityInWorld(item);

<p>This code calls DropDB and selects a random drop from a registered list. The list is perfectly fine. Here is the code for getDrop is:</p>
<pre><code> public static DropBase getRandomDrop() {
Random rand = new Random();
int n = rand.nextInt(drops.size()) + 1;
System.out.println(n);
System.out.println(drops.size());
return drops.get(n);

<p>This code causes this error. I have tired to look at the other questions around here. They <em>have not</em> worked. </p>

JMeter distributed server not sending results back to master server
|
<p>Issue: Remote Jmeter server is not reporting back the results to the master server.</p>
<p>Description:
Using a VMware server I have added several Ubuntu servers hosting various JMeter client/servers. I have setup a very simple distributed Jmeter environment using one master and one remote slave. I have a very simple test plan that uses FTP to transfer a single file to a third FTP server.</p>
<p>Jmeter Master: 192.168.19.219, Ubuntu 12.04, Java 1.7.0.51, Jmeter 2.11
Jmeter Slave: 192.168.19.201, Ubuntu 12.04, Java 1.7.0.51, Jmeter 2.11
FTP Server 192.168.19.211, Win2008 R2</p>
<p>Upon execution the test plan works correctly and the file gets uploaded and downloaded successfully to and from the FTP server. Whats not working are the results. Using wireshark I determined that no results were being sent back to the master server. I then checked the jmeter-server.log and noticed some errors complaining about java.rmi.ConnectException. Its trying to use 127.0.0.1 which is obviously not the correct address. I read up and found to correct this you must set the param "java.rmi.server.hostname". </p>
<p>So on the slave server I edited the jmeter-server config file to the IP address of the slave server:
RMI_HOST_DEF=-Djava.rmi.server.hostname=192.168.19.201 </p>
<p>The jmeter-server.log (attached) shows the java.rmi.server.hostname being picked up so I cannot figure out why further down in the jmeter-server.log its complaining about 127.0.0.1? Where is 127.0.0.1 coming from? Why is RMI not using 192.168.19.201?</p>
<p>Jmeter-server.log:</p>

Why I received an Error 403 with MockMvc and JUnit?
|
<p>I have a spring mvc (3.2.5) application with spring security (3.2). </p>
<p>I configured my SecurityConfig.class with this method : </p>
<pre><code>@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().antMatchers("/*").permitAll().and()
.formLogin().successHandler(successHandler)
.defaultSuccessUrl("/")
.failureHandler(failureHandler).failureUrl("/login?error=true")
.permitAll().and().logout()
.permitAll();
http.authorizeRequests().antMatchers("/resources/**").permitAll();
http.authorizeRequests().antMatchers("/welcome").permitAll();
http.authorizeRequests().antMatchers("/secure/*").authenticated();
http.authorizeRequests().antMatchers("/admin/**").hasRole("ADMIN").anyRequest().authenticated();
}
</code></pre>
<p>With Spring security (3.2) I have CSRF enabled. I think it is a good idea to let it enabled.</p>
<p>My controller SignInController contains 2 methods with params :</p>
<p><em>EDIT</em> : adding <code>action=</code> in params </p>
<pre><code>@RequestMapping(value = "/signup")
public ModelAndView signup() {
boolean auth = SecurityContextHolder.getContext().getAuthentication() == null ? false
: SecurityContextHolder.getContext().getAuthentication()
.isAuthenticated()
&& (SecurityContextHolder.getContext()
.getAuthentication().getPrincipal() instanceof User);
ModelAndView result = null;
if (auth) {
result = new ModelAndView("redirect:" + "/");
} else {
UserForm user = new UserForm();
result = new ModelAndView("registration", "userForm", user);
}
return result;
}
@RequestMapping(value = "/register", params = "action=signup")
public ModelAndView registration(
@ModelAttribute(value = "userForm") @Valid UserForm userForm,
BindingResult result, HttpServletRequest request) {
if (result.hasErrors()) {
return new ModelAndView("registration");
}
Member member = profileFacade.registerNewUser(userForm);
return new ModelAndView("registration", "member", member);
}
@RequestMapping(value = "/register", params = "action=cancel")
public ModelAndView cancelRegistration() {
return new ModelAndView("redirect:" + "/");
}
</code></pre>
<p>and finally, I have JUnit test :</p>
<pre><code>@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(classes = { WebConfiguration.class,
JpaConfiguration.class, LoggingConfiguration.class,
SecurityConfig.class, DataSourceEmbeddedConfiguration.class,
DataSourceMySqlConfig.class, BaseValidatorConfiguration.class })
@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true)
@ActiveProfiles("dev")
public class SignInControllerTest {

@Autowired

this.mockMvc = MockMvcBuilders
.webAppContextSetup(this.webApplicationContext)

SecurityContextHolder.getContext().setAuthentication(null);
}
@Test
public void signup() throws Exception {
mockMvc.perform(get("/signup")).andExpect(status().isOk())
.andExpect(model().attributeExists("userForm"));
}
@Test
@Transactional
@Rollback(true)
public void register() throws Exception {
UserForm form = new UserForm();
form.setEmail("email@email.com");
form.setUsername("aokije");
form.setPassword("klo,ksff");
form.setConfirmedPassword("klo,ksff");
mockMvc.perform(post("/register").param("action", "signup")).andExpect(status().isOk());
}
}
</code></pre>
<p><em>EDIT</em> : update mockMvc.perform because it is working fine with <code>http.csrf().disable()</code> in SecurityConfig.class</p>
<p>Test <strong><em>signup</em></strong> run perfectly but <strong><em>register</em></strong> return an error 403.
I tried a lot of things but I received always this error.</p>
<p>When I try <code>http://localhost:8080/register?signup</code> in a browser, it is working fine.</p>

BootStrap Table text ellipsis can not be with responsive web?
|
<p>I am trying to implement String ellipsis in the Table tag.</p>
<p>The source code is below.</p>
<pre><code><div>
<div class="widget-body no-padding" style="min-height:0px;">
<table class="table" style="table-layout: fixed;">
<tbody>
<c:forEach var="item" items="${result.stuffList}" varStatus="idx">
<c:if test="${idx.index < 5}">
<tr>
<td class='text-center' style="width: 80%; text-overflow:ellipsis; -o-text-overow: ellipsis; word-wrap:normal; overflow: hidden;">
<nobr>
<a href="#" onclick="javascript:location.href='/view?nid=${item.id}'">${item.name}</a>
</nobr>
</td>
<td class='text-center' style="width: 20%;">
${item.regDate}
</td>
</tr>
</c:if>
</c:forEach>
</tbody>
</table>
</div>
</div>
</code></pre>
<p>This code works and if String is too long it shows <code>...</code> what I expected.</p>
<p>However, when I test responsive it becomes ugly.</p>
<p>I wrote following part to express item registration date.</p>
<p>But when browser shrinks, its back part does not showed up in screen. </p>
<pre><code><td class='text-center' style="width: 20%;">
${item.regDate}
</td>
</code></pre>
<p>How can I use ellipsis in Bootstrap in all browser?</p>
<hr>
<p>So it appears like this way</p>
<p>What I expected(when shrink browser) >></p>
<p>column 1 / column 2</p>
<p>AAAA.... / 2014-09-24</p>
<p>What now looks like >></p>
<p>column 1 / column 2</p>
<p>AAAA.... / 2014-09</p>
<p>The problem is >> </p>
<p>Before I add String ellipsis function it works responsive.</p>
<p>My guess >></p>
<p>Maybe <code>table-layout: fixed;</code> style is the cause. but do not know how to implements String ellipsis function without <code>table-layout</code>.</p>
<p>I hope it becomes more clear than I asked first :D</p>
<hr>
<p>I have got the cause</p>
<p>The problem is width : <code>80%</code>, <code>width: 20%</code>, <code>table-layout:fixed</code>.</p>
<p>So when I resize the browser it takes these options for it.</p>
<p>But I still do not know how to replace it.</p>
<p>All of these are in a div which is small part of the web site and I want responsive web. </p>
<hr>
<p>Edited after choose an answer.</p>
<p>Thanks for answering my question!</p>
<p>However I found the cause, but could not fix this.</p>
<p>The chosen answer was not relevant, however it was helpful.</p>
<p>My problem was not by bootstrap, but width.</p>
<p>Even though using responsive web library, </p>
<p>can not be responsive if you use width with <code>%</code> or <code>px</code> properties.</p>

<p>The problem I'm having is that when passing the bundle from the caller activity it is like this,</p>
<pre><code>Bundle[{reminder=au.com.elegantmedia.vetcheck.objects.Reminder@41fade98, mode=edit}]
</code></pre>
<p>meaning everything is set as expected, but when trying to access the extras from the callee activity (<code>final Bundle bundle = getIntent().getExtras();</code>) it is as follows,</p>
<pre><code>Bundle[mParcelledData.dataSize=308]
</code></pre>
<p>and at the point I try to access the bundle as follows,</p>
<pre><code>if(bundle.getString(EXTRA_MODE).equals(MODE_ADD)) {
}
else if(bundle.getString(EXTRA_MODE).equals(MODE_EDIT)) {
final Reminder reminder = getIntent().getParcelableExtra(EXTRA_REMINDER);
populateData(reminder);
}
</code></pre>
<p>I run into the following Exception</p>

<p>This is my first attempt on Parcelable objects so I have very little idea what this means and Googling for a couple of hours hasn't exactly helped to narrow down the problem.</p>

Could not load file or assembly 'XXXX.dll' or one of its dependencies. The specified module could not be found
|
<p>I have an application that directly references a dll file: <code>POSLink.dll</code>. </p>
<p>In order to get this to run on my local machine, I have to manually copy the following dlls to the output directory: <code>libea32.dll</code> and <code>ssleay32.dll</code>.</p>
<p>When I run the application on my local machine, it succeeds.</p>
<p>When I run the application on the target machine, I get the following error:</p>

<p>I tried using <a href="http://www.dependencywalker.com/" rel="nofollow">Dependency Walker</a> on POSLink.dll, but that wasn't very useful to me because there are 381 errors that show up, and they show up when I run it on the successful machine too. </p>

Change spinner style in toolbar
|
<p>I am trying to put a spinner in my <code>Toolbar</code> like the old ActionBar style navigation and my theme is this</p>
<pre><code><style name="AppBaseTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">@color/color_primary</item>
<item name="colorPrimaryDark">@color/color_primary_dark</item>
<item name="colorAccent">@color/color_primary</item>
</style>
</code></pre>
<p>but my spinner is black while all other icons and overflow menus are white so it looks bad</p>
<p><img src="https://i.stack.imgur.com/4ROO4.png" alt="enter image description here"></p>
<p>I tried changing the style of the spinner using this</p>
<pre><code><style name="ToolbarSpinnerTheme" parent="Theme.AppCompat">
<item name="android:spinnerItemStyle">@style/TextAppearanceSpinnerItem</item>
</style>
<style name="TextAppearanceSpinnerItem">
<item name="android:textColor">#FFFFFF</item>
</style>
</code></pre>
<p>this is how my Toolbar is styled</p>
<pre><code><android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light">
<Spinner
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/modes"
android:minWidth="150dp"
android:gravity="bottom"
style="@style/ToolbarSpinnerTheme"/>
</android.support.v7.widget.Toolbar>
final Spinner mode = (Spinner)findViewById(R.id.modes);
SpinnerAdapter mSpinner = ArrayAdapter.createFromResource(this, R.array.action_bar_spinner, android.R.layout.simple_spinner_dropdown_item);
mode.setAdapter(mSpinner);
</code></pre>
<p>but it always stays black. How can I change the spinner arrow and text to white while still keeping the same theme for the dropdown style as you would get with the <code>Light</code> theme?</p>
<p><strong>Update 4.4 arrow fix:</strong> </p>
<p>The only way I got the arrow to turn white is to add the spinner programatically and not in xml so it looks something like this</p>
<pre><code>final ArrayAdapter spinnerAdapter = ArrayAdapter.createFromResource(getSupportActionBar().getThemedContext(),
R.array.main_navigation_list, R.layout.spinner_text);
spinnerAdapter.setDropDownViewResource(R.layout.spinner_dropdown_item);
mNavigationTags = getResources().getStringArray(R.array.main_navigation_list);
mNavigationSpinner = new Spinner(getSupportActionBar().getThemedContext());
mNavigationSpinner.setAdapter(spinnerAdapter);
mNavigationSpinner.setOnItemSelectedListener(this);
mToolbar.addView(mNavigationSpinner)

How to open a jdialog from a jframe
|
<p>JFrame button to open the jdialog:</p>
<pre><code>private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
</code></pre>
<p>JDialog method that opens the dialog:</p>
<pre><code> public void run() {
AddClient dialog = new AddClient(new javax.swing.JFrame(), true);
dialog.addWindowListener(new java.awt.event.WindowAdapter() {
@Override
public void windowClosing(java.awt.event.WindowEvent e) {
System.exit(0);
}
});
dialog.setVisible(true);
</code></pre>
<p>My JDialog class is named AddClient, my JFrame class is named MainWindow. The package these are in is named my.javaapp</p>
<p>How would i go onto doing this? I'm pretty new to java, was using python up until this point and dove head in into java swing gui builder with netbeans, i'm planning on watching tutorials and reading through the java documentation to learn more about java, but i would like to start by being able to open this jdialog.</p>
<p><em>Before asking this question i searched a lot, and i read other questions that had been asked to solve more or less this same problem, i still couldn't solve mine though so i'm asking.</em></p>
<p><strong>Solution:</strong></p>
<p>Delete the main function from the class the gui you want to pop up is on e.g</p>
<pre><code>public static void main(String args[]) {
try {
for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) {
if ("Nimbus".equals(info.getName())) {
javax.swing.UIManager.setLookAndFeel(info.getClassName());
break;
}
}
} catch (ClassNotFoundException ex) {
java.util.logging.Logger.getLogger(NewJDialog1.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
} catch (InstantiationException ex) {
java.util.logging.Logger.getLogger(NewJDialog1.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
} catch (IllegalAccessException ex) {
java.util.logging.Logger.getLogger(NewJDialog1.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
} catch (javax.swing.UnsupportedLookAndFeelException ex) {
java.util.logging.Logger.getLogger(NewJDialog1.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
}
//</editor-fold>
/* Create and display the dialog */
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
NewJDialog1 dialog = new NewJDialog1(new javax.swing.JFrame(), true);
dialog.addWindowListener(new java.awt.event.WindowAdapter() {
@Override
public void windowClosing(java.awt.event.WindowEvent e) {
System.exit(0);
}
});
dialog.setVisible(true);
}
});
}
</code></pre>
<p>Before deleting though, copy this line:</p>
<pre><code>NewJDialog1 dialog = new NewJDialog1(new javax.swing.JFrame(), true);
</code></pre>
<p>Right click the button you want to pop this window up after pressing, events > action > action performed. Paste it there like this:</p>
<pre><code>private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
NewJDialog1 dialog = new NewJDialog1(new javax.swing.JFrame(), true);
dialog.setVisible(true);
}
</code></pre>
<p>Remember to add the last line, that's what shows up the dialog.</p>

<p>I want the last button with id btn_delete to stay right aligned. And its showing as I wanted in "graphical layout" while designing. But when I run it, on emulator it's not working. </p>
<p>See the output :</p>
<p><img src="https://i.stack.imgur.com/kcFIz.png" alt="enter image description here"></p>
<p>So why the delete button not getting right aligned?</p>

Telnet to cisco switch using php

<p>I need to telnet to cisco switch using php and execute <code>show interface status</code> command and get results. I tried some php classes I found on internet but none of them could connect to device. So I tried to write the script myself, but I have the same problem, I cant connect to device.</p>
<p>The host sends me banner message and then new line with <code>username:</code>.
I send my username with <code>\r\n</code>, wait some time and tries to read data, but it looks to me like host is just ignoring my new line characters. This is response I got (explode('\n') on response):</p>

[0] => %
[1] => User Access Verification

<p><strong>UPDATE</strong>
If I send username at first, and then I read, I get password prompt. I dont understand it, why cant I firstly read messages from host and then send my response. The way it works to me now (send response and then read for prompt) is no-sense! (and I still got "% Authentication failed." message event with right password/name).</p>
<pre><code>...
$connected = true;
stream_set_timeout($fw, $timeout);
send_string("name", true);
send_string("password", true);
print_r(read_string());

I can't find populateViewHolder Method in FirebaseRecyclerAdapter class
|
<p>I want to use <code>FirebaseRecyclerAdapter</code> in my project and I used this code segment in a previous Project</p>
<pre><code>FirebaseRecyclerAdapter<ChatMessage, ChatMessageViewHolder> adapter = new FirebaseRecyclerAdapter<ChatMessage, ChatMessageViewHolder>(ChatMessage.class, android.R.layout.two_line_list_item, ChatMessageViewHolder.class, ref) {
public void populateViewHolder(ChatMessageViewHolder chatMessageViewHolder, ChatMessage chatMessage, int position) {
chatMessageViewHolder.nameText.setText(chatMessage.getName());
chatMessageViewHolder.messageText.setText(chatMessage.getMessage());
}
};
recycler.setAdapter(mAdapter);
</code></pre>
<p>and it was working fine but now it doesn't work any more, Is there any update in the new version of <code>FirebaseUi</code> that can't allow me to reuse this code now?</p>
<p><strong>I tried this in my project</strong></p>
<pre><code> @Override

blogListViewHolder.postTitle.setText(blogModel.getPostTitle());
blogListViewHolder.postDesc.setText(blogModel.getPostDesc());

<p>I am trying to add a private key into the iOS keychain. The certificate (public key) works fine but the private key refuses... I am totally confused why the following code does not work.</p>
<p>First I am checking if the current key (=key in case of that the Keychain is a key/value store) is 'free' in the Keychain. Then I am going to add the private key.</p>
<pre><code>CFStringRef labelstring = CFStringCreateWithCString(NULL, [key cStringUsingEncoding:NSUTF8StringEncoding], kCFStringEncodingUTF8);
NSArray* keys = [NSArray arrayWithObjects:(__bridge id)kSecClass,kSecAttrLabel,kSecReturnData,kSecAttrAccessible,nil];
NSArray* values = [NSArray arrayWithObjects:(__bridge id)kSecClassKey,labelstring,kCFBooleanTrue,kSecAttrAccessibleWhenUnlocked,nil];
NSMutableDictionary* searchdict = [NSMutableDictionary dictionaryWithObjects:values forKeys:keys];
CFRelease(labelstring);
NSMutableDictionary *query = searchdict;
CFTypeRef item = NULL;
OSStatus error = SecItemCopyMatching((__bridge_retained CFDictionaryRef) query, &item);
if (error)
{
NSLog(@"Error: %ld (statuscode)", error);
}
if(error != errSecItemNotFound)
{
SecItemDelete((__bridge_retained CFDictionaryRef) query);
}
[query setObject:(id)data forKey:(__bridge id)kSecValueData];
OSStatus status = SecItemAdd((__bridge_retained CFDictionaryRef) query, &item);
if(status)
{
NSLog(@"Keychain error occured: %ld (statuscode)", status);
return NO;
}
</code></pre>
<p>The debug output is the following:</p>
<pre><code>2012-07-26 15:33:03.772 App[15529:1b03] Error: -25300 (statuscode)
2012-07-26 15:33:11.195 App[15529:1b03] Keychain error occured: -25299 (statuscode)
</code></pre>
<p>The first error code <code>-25300</code> represents <code>errSecItemNotFound</code>. So there is no value stored for this key. Then, when I try to add the private key into the Keychain I get <code>-25299</code> which means <code>errSecDuplicateItem</code>. I do not understand this. Why is this happening?</p>
<p>Does anyone have a clue or hint on this?</p>
<p>Apple's error codes:</p>
<pre><code>errSecSuccess = 0, /* No error. */
errSecUnimplemented = -4, /* Function or operation not implemented. */
errSecParam = -50, /* One or more parameters passed to a function where not valid. */
errSecAllocate = -108, /* Failed to allocate memory. */
errSecNotAvailable = -25291, /* No keychain is available. You may need to restart your computer. */
errSecDuplicateItem = -25299, /* The specified item already exists in the keychain. */
errSecItemNotFound = -25300, /* The specified item could not be found in the keychain. */
errSecInteractionNotAllowed = -25308, /* User interaction is not allowed. */
errSecDecode = -26275, /* Unable to decode the provided data. */
errSecAuthFailed = -25293, /* The user name or passphrase you entered is not correct. */
</code></pre>
<p>Thanks in advance!</p>
<p><strong>Update #1: I've figured out that it works only for the first time. Even when data and key is different, after the first time stored into the keychain I cannot store further keys.</strong></p>

How do I get a ListPopupWindow to work with a custom adapter?
|
<p>I want to display a simple array of strings in a ListPopupWindow that is shown on a button click. I'm running into problems however, as when I do some minimal setup of either an <code>ArrayAdapter<String></code> or a custom-built adapter, I run into a resources not found exception when I go to show the popup window. Here is the code I'm using (with the stack trace after it). Any ideas as to what is happening?</p>
<pre><code>public class AndroidSandboxActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final Button btn = (Button)findViewById(R.id.btn1);
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
showListPopup(btn);
}
});
}
public void showListPopup(View anchor) {
ListPopupWindow popup = new ListPopupWindow(this);
popup.setAnchorView(anchor);
ListAdapter adapter = new MyAdapter(this);
popup.setAdapter(adapter);
popup.show();
}
public static class MyAdapter extends BaseAdapter implements ListAdapter {
private final String[] list = new String[] {"one","two","three"};
private Activity activity;
public MyAdapter(Activity activity) {
this.activity = activity;
}
@Override
public int getCount() {
return list.length;
}
@Override
public Object getItem(int position) {
return list[position];
}
@Override
public long getItemId(int position) {
return position;
}
private static int textid = 1234;
@Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView text = null;
if (convertView == null) {
LinearLayout layout = new LinearLayout(activity);
layout.setOrientation(LinearLayout.HORIZONTAL);
text = new TextView(activity);
text.setId(textid);
layout.addView(text);
convertView = layout;
} else {
text = (TextView)convertView.findViewById(textid);
}
text.setText(list[position]);
return convertView;
}
}
}
</code></pre>
<p>And here's the stack trace (the thing that boggles my mind is that it says it's using an <code>ArrayAdapter</code> when I'm using my own custom adapter):</p>
<pre><code>Thread [<1> main] (Suspended (exception Resources$NotFoundException))

C# How to await a method that returns Task<dynamic>?
|
<p>I have a method that is parsing the results from a JSON object. The method returns a Task object but when I run the code, I am getting the following error:</p>
<pre><code>'System.Collections.Generic.Dictionary<string,object>' does not contain a definition for 'GetAwaiter'
</code></pre>
<p>The object returned from the dynamic method is an array of objects of type System.Collections.Generic.Dictionary and System.Collections.Generic.KeyValuePair. Here is the code:</p>
<pre><code>private static async Task<dynamic> GetReslutstAsync(string url)
{
WebRequest request;
WebResponse response = null;
try
{
request = WebRequest.Create(url);
request.Credentials = new NetworkCredential("username", "password", "company");
//request.Credentials = CredentialCache.DefaultNetworkCredentials;
response = await request.GetResponseAsync();
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}
using (var reader = new StreamReader(response.GetResponseStream()))
{
try
{
JavaScriptSerializer js = new JavaScriptSerializer();
var objects = js.Deserialize<dynamic>(reader.ReadToEnd());
return objects;
}
catch (Exception e)
{
Console.WriteLine(e.Message);
return null;
}
}
}
</code></pre>
<p>The exception occurs here:</p>
<pre><code>private static async Task<dynamic> MakeRequest(string url)
{
try
{
return await GetReslutstAsync(url).Result; //<---- This is where I get the error!
}
catch (Exception e)
{
Console.WriteLine(e.Message);
return null;
}
}
</code></pre>
<p>I believe this has something to do with the fact that I am returning a dynamic type object. How can I get around this? I need to await this task inside the "MakeRequest" method so that it does not continue until the request is completed.</p>
<p>EDIT: </p>
<p>My "MakeRequest" method is in a loop like this:</p>
<pre><code>while (true)
{
ClockTimer timer = new ClockTimer();
timer.StartTimer(); //<---This does not stop untill 5 sec has passed
MakeRequest("www.someurl.com"); //<--- This just skips into the next loop even if not complete.
}
</code></pre>
<p>My issue is that <code>MakeRequest</code> is being run asynchronously so basically, it just skips over this and goes right into the next loop. I need "MakeRequest" to HALT until the request is finished. I have tried removing all async/await keywords but this just results in "Result was not calculated".</p>

Angular 4 Dynamic form with nested groups

<p>I want to generate a reactive form from the tree structure.</p>
<p>Here is the code that creates the form items (form groups and controls). For the controls nested in form group it I use a recursive template.</p>

Java: no security manager: RMI class loader disabled

<p>Hi I have RMI application and now I try to invoke some methods at server from my client. I have following code:</p>

Display data from SQLite database into ListView in Android
|
<p>Although this question has been asked many times on here, I just can't find the proper answer to fit my code. I realise it may be something small, but I just can't seem to find the problem as I'm only really new to this.</p>
<p>Here's my code <strong>getClientNames</strong> in <strong>DatabaseHelper</strong> class:</p>
<pre><code>public Cursor getSitesByClientname(String id) {
String[] args={id};
Cursor myCursor = db.rawQuery("SELECT client_sitename FROM " + CLIENT_SITES_TABLE + " WHERE client_id=?", args);
String results = "";
/*int count = myCursor.getCount();
String[] results = new String[count + 1];
int i = 0;*/
if (myCursor != null) {
if(myCursor.getCount() > 0)
{
for (myCursor.moveToFirst(); !myCursor.isAfterLast(); myCursor.moveToNext())
{
results = results + myCursor.getString(myCursor.getColumnIndex("client_sitename"));
}
}
}
return results;
}
</code></pre>
<p>One problem is that I'm returning a 'String' to the 'Cursor', but I'm not sure what is the best way around this, as I think I should be returning a Cursor.</p>
<p>Here's the <strong>ClientSites</strong> class where I want to display the data:</p>
<pre><code>public class ClientSites extends Activity {
//public final static String ID_EXTRA="com.example.loginfromlocal._ID";
private DBUserAdapter dbHelper = null;
private Cursor ourCursor = null;
private Adapter adapter=null;

@SuppressLint("NewApi")
public void onCreate(Bundle savedInstanceState) {
try
{
super.onCreate(savedInstanceState);
setContentView(R.layout.client_sites);
Intent i = getIntent();
String uID = String.valueOf(i.getIntExtra("userID", 0));
ListView myListView = (ListView)findViewById(R.id.myListView);
dbHelper = new DBUserAdapter(this);

//Toast.makeText(ClientSites.this, "Booo!!!", Toast.LENGTH_LONG).show();
myListView.setAdapter(adapter);
myListView.setOnItemClickListener(onListClick);
}
catch (Exception e)
{
Log.e("ERROR", "XXERROR IN CODE: " + e.toString());
e.printStackTrace();
}
}
private AdapterView.OnItemClickListener onListClick=new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent,
View view, int position,
long id)
{
Intent i=new Intent(ClientSites.this, InspectionPoints.class);
i.putExtra(ID_EXTRA, String.valueOf(id));
startActivity(i);
}
};
class Adapter extends CursorAdapter {
@SuppressWarnings("deprecation")

super(ClientSites.this, c);
}
//@Override
public void bindView(View row, Context ctxt,
Cursor c) {
Holder holder=(Holder)row.getTag();

}
@Override
public View newView(Context ctxt, Cursor c,
ViewGroup parent) {
LayoutInflater inflater=getLayoutInflater();
View row = inflater.inflate(R.layout.row, parent, false);
Holder holder=new Holder(row);
row.setTag(holder);
return(row);
}
}
static class Holder {
private TextView name=null;

name=(TextView)row.findViewById(R.id.ingredientText);
}
void populateFrom(Cursor c, DBUserAdapter r) {
name.setText(r.getName(c));
}
}
}
</code></pre>
<p>Here is the code I'm now using to try and display the data in the Listview. I have altered it somewhat from my original attempt, but still not sure what I'm doing wrong.</p>
<pre><code>public void onCreate(Bundle savedInstanceState) {
try

super.onCreate(savedInstanceState);
//setContentView(R.layout.client_sites);

jboss-as-maven-plugin can't deploy to remote JBoss AS7?
|
<p>I've tried for days to use <code>jboss-as-maven-plugin</code> to deploy web projects to remote JBoss AS7, but it didn't work. </p>
<p>Here is my <code>pom.xml</code>: </p>
<pre><code><!-- JBoss Application Server -->
<plugin>
<groupId>org.jboss.as.plugins</groupId>
<artifactId>jboss-as-maven-plugin</artifactId>
<version>7.1.0.CR1b</version>

<!-- Only remote server needs -->
<configuration>
<hostname>192.168.1.104</hostname>
<port>9999</port>
<username>admin</username>
<password>admin123</password>
</configuration>
</execution>
</executions>
</plugin>
</code></pre>
<p>Using this configuration I can deploy to <strong>localhost</strong> without <code><configuration></code>, even no <code><username></code> and <code><password></code>.</p>
<p>To deploy to my real IP address, I modified <strong>${JBOSS_HOME}/configuration/standlone.xml</strong>, by changing <code>jboss.bind.address</code> from <strong>127.0.0.1</strong> to <strong>0.0.0.0</strong> (to unbind JBoss address), so I can deploy projects by using:</p>
<pre><code><configuration>
<!-- 192.168.1.106 is my ip -->
<hostname>192.168.1.06</hostname>
<port>9999</port>
</configuration>
</code></pre>
<p>It works too, but by changing <code><hostname></code> to point to my other computer (in the same router) it doesn't work but that computer receives a request, and the request is cut by something. (I thought it may be JBoss)</p>
<p>The error message in Maven console is as follows:</p>
<pre><code> INFO: JBoss Remoting version 3.2.0.CR8

Bootstrap carousel with responsive HTML5 videos?
|
<p>I'm trying to make a carousel with videos. With the images it works fine the image are responsive even in mobile view. But with videos the width is responsive but not the height. Basically I would like to achieve the same comportement with a carousel image but with a video. I've tried many tricks online but none is doing it. My video is 1024/552px</p>
<p>Tried my best at a fiddle. You can see if you load the fiddle with a small width, it keeps the same height and it isn't responsive but the width of the carousel/video is (it crops the video on the sides though). It doesn't have the same comportement as an image. As you will see I have included an image in the second slide to further demonstrate my problem. </p>
<p><a href="https://jsfiddle.net/687bsb21/1/" rel="noreferrer">https://jsfiddle.net/687bsb21/1/</a></p>
<p>Here's the code :</p>
<pre><code><div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">
<li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
<li data-target="#carousel-example-generic" data-slide-to="1"></li>
</ol>
<!-- Wrapper for slides -->
<div class="carousel-inner" role="listbox">
<div class="item active">
<div align="center">
<video autoplay loop>
<source src="http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4" width="1024" height="552" type="video/mp4">
Your browser does not support the video tag.
</video>
</div>

std::unique_ptr deleted function, initializer_list - driven allocation
|
<p>All, </p>
<p>When I instantiate a widgets array using an initializer-list format, a naked pointer that points to a member-variable widget instance compiles but after change to std::unique_ptr<> gcc gives a compilation error regarding a deleted function. </p>
<p>$ uname -a </p>
<p>Linux .. 3.5.0-21-generic #32-Ubuntu SMP Tue Dec 11 18:51:59 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux</p>
<p>$ g++ --version</p>
<p>g++ (Ubuntu/Linaro 4.7.2-5ubuntu1) 4.7.2</p>
<p>This code gives the following compiler error:</p>
<pre><code>#include <stdlib.h>
#include <memory>
class Widget
{
public:
Widget() {}
};
class W1 : public Widget
{
public:
W1() {}
};
class W2 : public Widget
{
public:
W2() {}
};
class WFactory
{
public:
WFactory(const int i) : _w(new W1()) {}
WFactory(const char* s) : _w(new W2()) {}
~WFactory() { _w.reset(nullptr); }
// ~WFactory() { delete _w; } <--- for naked ptr
private:
// NOTE: does not compile
std::unique_ptr<Widget> _w;
// NOTE: does compile
// Widget* _w;
};
int main()
{
std::unique_ptr<Widget> a(new W1()); // <--- compiles fine
WFactory wf[] { 4, "msg" }; // <--- compiler error using unique_ptr<>
}
</code></pre>
<p>error:</p>

</code></pre>
<p>I'm at a loss as to either: the mechanics behind the scenes that yields a deleted fcxn; or more simply, why the expressiveness of std::unique_ptr<> appears to be restricted compared w/ a naked ptr.</p>
<p>My question is:</p>
<ul>
<li>pilot error?</li>
<li>compiler error? </li>
<li>can I get my intended code to work w/ some change?</li>
</ul>
<p>Thank you.</p>
<p><strong>Edit 1</strong></p>
<p>Based on your answers, which I appreciate, I can make the following change to WFactory:</p>
<p>(<strong>flagged as immoral code</strong>)</p>
<pre><code>class WFactory
{
public:
WFactory(const WFactory& wf)
{
(const_cast<WFactory&>(wf)).moveto(_w);
}
WFactory(const int i) : _w(new W1()) {}
WFactory(const char* s) : _w(new W2()) {}
~WFactory() { _w.reset(nullptr); }
void moveto(std::unique_ptr<Widget>& w)
{
w = std::move(_w);
}
private:
std::unique_ptr<Widget> _w;
};
</code></pre>
<p>and now the program compiles and runs. I appreciate that the standards folks wrote the specification for a reason, so I post my result as a good-faith specialization for my case at hand, where I really would like to emphasize the uniqueness of the ptr. </p>
<p><strong>Edit 2</strong></p>
<p>Based on Jonathan's replies, the following code does not suppress the implicit move ctor:</p>
<pre><code>class WFactory
{
public:
WFactory(const int i) : _w(new W1()) {}
WFactory(const char* s) : _w(new W2()) {}
private:
std::unique_ptr<Widget> _w;
};
</code></pre>
<p>Note that there is no <code>~WFactory() {..}</code> at all. </p>
<p>Perhaps there's ya-ans, but I have found that using a c++11-style iteration over wf[] in Main() brings back the no-copy-ctor-for-WFactory error. That is:</p>
<pre><code>int Main()
..
WFactory wf[] { 4, "msg" };
for ( WFactory iwf : wf ) <---- compiler error again
// ..
for (unsigned i = 0; i < 2; ++i) <--- gcc happy
wf[i] // ..
}
</code></pre>
<p>I guess it's self-evident that the new c++11-style iteration is doing an object copy. </p>

Tomcat error: The origin server did not find a current representation for the target resource or is not willing to disclose that one exists

Generate SSL Certificate using keytool provide in jdk
|
<p>Keystore files I have used in my web application expired last week. I generated it long time ago. So I started generating new certificate using keytool. I used this certificate to connect a transaction server and the web server. I wanted to use self signed certificate for this application. I generate it using following command to generate self signed key for transaction server. </p>
<pre><code>keytool -genkey -keystore keys/SvrKeyStore -keyalg rsa -validity 365 -alias Svr -storepass 123456 -keypass abcdefg -dname "CN=One1, OU=Development1, O=One, L=Bamba, S=Western Prov1, C=S1"
</code></pre>
<p>following commnad to generate keystore for web application</p>
<pre><code>keytool -genkey -keystore keys/ClientKeyStore -keyalg rsa -validity 365 -alias Web -storepass 123456 -keypass abcdefg -dname "CN=One, OU=Development, O=One, L=Bamba, S=Western Prov, C=SL"
</code></pre>
<p>I used following code in the transaction server to create the socket connection</p>
<pre><code> String KEYSTORE = Config.KEYSTORE_FILE;//SvrKeyStore keystore file
char[] KEYSTOREPW = "123456".toCharArray();
char[] KEYPW = "abcdefg".toCharArray();
com.sun.net.ssl.TrustManagerFactory tmf;
boolean requireClientAuthentication;
java.security.Security.addProvider(new com.sun.net.ssl.internal.ssl.
Provider());
java.security.KeyStore keystore = java.security.KeyStore.getInstance(
"JKS");
keystore.load(new FileInputStream(KEYSTORE), KEYSTOREPW);
com.sun.net.ssl.KeyManagerFactory kmf = com.sun.net.ssl.
KeyManagerFactory.getInstance("SunX509");
kmf.init(keystore, KEYPW);
com.sun.net.ssl.SSLContext sslc = com.sun.net.ssl.SSLContext.
getInstance("SSLv3");
tmf = com.sun.net.ssl.TrustManagerFactory.getInstance("sunx509");
tmf.init(keystore);
sslc.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
SSLServerSocketFactory ssf = sslc.getServerSocketFactory();
SSLServerSocket ssocket = (SSLServerSocket) ssf.createServerSocket(port);
ssocket.setNeedClientAuth(true);
</code></pre>

Flutter Firestore causing D8: Cannot fit requested classes in a single dex file (# methods: 71610 > 65536) in Android Studio
|
<p>I am attempting to use firestore with a Flutter app in latest version of Android Studio. I have followed these instructions exactly. <a href="https://www.youtube.com/watch?v=DqJ_KjFzL9I&list=PLjxrf2q8roU2HdJQDjJzOeO6J3FoFLWr2&index=9" rel="noreferrer">https://www.youtube.com/watch?v=DqJ_KjFzL9I&list=PLjxrf2q8roU2HdJQDjJzOeO6J3FoFLWr2&index=9</a> I even got them to work last week with a different app. Now I get the following error when I attempt to run my new app after completing all the steps up to (and including) updating pubspec.yaml. Keep in mind, in this example, i am getting the error on a fresh flutter counter app with no other code changes but what you see here.</p>

Angular Material - Filter Table by multiple filters and multiple filter values at the same time
|
<p>I'm trying to be able to have two different filters for a table of objects. The first one is a normal text/input based filter and works as expected.</p>
<p>The second one I'm trying to get working is a row of checkboxes labeled "Level 1", "Level 2", etc. On checking a checkbox I want to filter by the column "level" all of the currently checked checkboxes. Ideally the user could filter the table by both the text and level selection</p>
<p>I've read about using filterPredicate and tried to use <a href="https://stackblitz.com/edit/angular-hbakxo-5jeaic?file=app%2Ftable-filtering-example.ts" rel="nofollow noreferrer">this as a template</a> but I must be missing something.</p>
<p>Current code snippet:</p>
<p>HTML:</p>
<pre><code>//Input for text filter
<mat-form-field >
<input matInput (keyup)="applyFilter($event.target.value)" placeholder="Filter...">
</mat-form-field>
...
//Checkboxes for level filter
<div fxLayout="row" fxLayoutAlign="space-between center" class="margin-1">
<mat-checkbox (change)="customFilterPredicate()" [(ngModel)]="level.active" *ngFor="let level of levelsToShow">{{level.level}}</mat-checkbox>
</div>
</code></pre>
<p>TS</p>
<pre><code>ngOnInit() {
this.dataSource.filterPredicate = this.customFilterPredicate();
}
...
applyFilter(filterValue: string) {
this.dataSource.filter = filterValue.trim().toLowerCase();
}
customFilterPredicate() {
const myFilterPredicate = (data): boolean => {
return this.levelsToShow.some(data['level'].toString().trim());
};
return myFilterPredicate;
}
</code></pre>
<h2>Update</h2>
<p>So far I was able to make some progress thanks to Fabian Küng but am still not home free. To clarify I'm hoping to have the text filter be able to search through multiple columns ('castingTime', 'duration', etc), and have the checkboxes only filter by level.</p>
<p>As of right now when I click on a checkbox I get this error:
'Cannot read property 'toLowerCase' of undefined'
that points to this line of code:</p>
<pre><code>return data['level'].toString().trim().toLowerCase().indexOf(searchString.name.toLowerCase()) !== -1 &&
</code></pre>
<p>but when I console log out data I can see that it has a level property, so I'm not seeing where I'm going wrong.</p>
<p>Here are the relevant code snippets:</p>
<pre><code> HTML:
<input matInput (keyup)="applyFilter($event.target.value)" placeholder="Filter..." [formControl]="textFilter">
<mat-checkbox (change)="updateFilter()" [(ngModel)]="level.active" *ngFor="let level of levelsToShow">{{level.name}}</mat-checkbox>
TS:
levelsToShow: Level[] = [
{ level: '1', active: false, name: 'Level 1' },
{ level: '2', active: false, name: 'Level 2' },
{ level: '3', active: false, name: 'Level 3' },
{ level: '4', active: false, name: 'Level 4' },
{ level: '5', active: false, name: 'Level 5' },
{ level: '6', active: false, name: 'Level 6' },
{ level: '7', active: false, name: 'Level 7' },
{ level: '8', active: false, name: 'Level 8' },
{ level: '9', active: false, name: 'Level 9' }
];
levelFilter = new FormControl();
textFilter = new FormControl();
globalFilter = '';
filteredValues = {
level: '',
text: '',
};
ngOnInit() {
...
this.textFilter.valueChanges.subscribe((textFilterValue) => {
this.filteredValues['text'] = textFilterValue;
this.dataSource.filter = JSON.stringify(this.filteredValues);
});
this.dataSource.filterPredicate = this.customFilterPredicate();
}
customFilterPredicate() {
const myFilterPredicate = (data: Spell, filter: string): boolean => {
var globalMatch = !this.globalFilter;
if (this.globalFilter) {
// search all text fields
globalMatch = data['spellName'].toString().trim().toLowerCase().indexOf(this.globalFilter.toLowerCase()) !== -1 ||
data['level'].toString().trim().toLowerCase().indexOf(this.globalFilter.toLowerCase()) !== -1 ||
data['castingTime'].toString().trim().toLowerCase().indexOf(this.globalFilter.toLowerCase()) !== -1 ||
data['distance'].toString().trim().toLowerCase().indexOf(this.globalFilter.toLowerCase()) !== -1 ||
data['details'].toString().trim().toLowerCase().indexOf(this.globalFilter.toLowerCase()) !== -1 ||
data['duration'].toString().trim().toLowerCase().indexOf(this.globalFilter.toLowerCase()) !== -1 ||
data['school'].toString().trim().toLowerCase().indexOf(this.globalFilter.toLowerCase()) !== -1 ||
data['effect'].toString().trim().toLowerCase().indexOf(this.globalFilter.toLowerCase()) !== -1;
}
if (!globalMatch) {
return;
}
let searchString = JSON.parse(filter);
return data['level'].toString().trim().toLowerCase().indexOf(searchString.name.toLowerCase()) !== -1 &&
(this.levelsToShow.filter(level => !level.active).length === this.levelsToShow.length ||
this.levelsToShow.filter(level => level.active).some(level => level.level === data.level.toString()));
}
return myFilterPredicate;
}
updateFilter() {
this.dataSource.filter = JSON.stringify(this.filteredValues);
}
</code></pre>
<h2>Update II</h2>
<p>As requested here is an example of one of the table rows: (this is for a d&d table of spells)</p>
<pre><code>{
castingTime: "1 half action"
distance: "Short range attack"
duration: "1 round per Casting Level"
effect: "Once per round, you may take a half action to launch an arrow of acid from your palm, generating a new Spellcasting result to see if you hit.Each arrow inflicts 1d6 acid damage.↵ "
index: 0
level: "4"
school: "Creation"
spellName: "ACID ARROW"
}
</code></pre>
<h2>Final Update</h2>
<p>This is what I ended up with in case anyone gets stuck. Thanks to Fabian Küng for figuring all this out! The only weird thing of note is that I ended up using the actual value of the text input "textFilter" because stringifying the text filteredValues and then parsing them (the filter only accepts strings as far as I can tell) kept giving me "JSON error, unexpected value at 0" messages and as far as I can tell this will work fine EXCEPT now I need to figure out how to throttle the filter.</p>
<pre><code>customFilterPredicate() {
const myFilterPredicate = (data: Spell, filter: string): boolean => {
var globalMatch = !this.globalFilter;
if (this.globalFilter) {
// search all text fields
globalMatch = data['spellName'].toString().trim().toLowerCase().indexOf(this.globalFilter.toLowerCase()) !== -1 ||
data['level'].toString().trim().toLowerCase().indexOf(this.globalFilter.toLowerCase()) !== -1 ||

Gradle refuse to start process command 'cmd'
|
<p>I'm encountering issue with a custom gradle task. Seems like gradle refuse to start a command line process.</p>
<p>Here is the custom task:</p>
<pre><code>task generateAllure(type: Exec) {
workingDir "$projectDir/allure/bin"
if (System.getProperty('os.name').toLowerCase(Locale.ROOT).contains('windows')) {
commandLine 'cmd', '/c', 'allure.bat', 'generate', '-c', '../../integration/build/allure-results'
} else {
commandLine 'bash', '-c', 'allure', 'generate', '-c',"$projectDir/integration/build/allure-results"
}
}
tasks.withType(Test)*.finalizedBy generateAllure
</code></pre>
<p>With the appropriate dependency:</p>
<pre><code>compile group: 'ru.yandex.qatools.allure', name: 'allure-commandline', version: '1.4.18'
</code></pre>
<p>After using <code>gradle clean test</code> execution fails on:</p>
<pre><code>2: Task failed with an exception.
-----------
* What went wrong:
Execution failed for task ':generateAllure'.
> A problem occurred starting process 'command 'cmd''
</code></pre>
<p>Any thoughts about that? Thanks!</p>
<p>UPD:
This is the stacktrace i'm getting after performing gradle -S clean test:</p>
<pre><code>* Exception is:

Autowiring not working in Spring 3.1.2, JUnit 4.10.0
|
<p>Using Spring 3.1.2, JUnit 4.10.0, and pretty new to both versions. I'm having the problem that I can't get the annotation-based autowiring to work.</p>
<p>Below are two samples, the one not using annotations, which is working fine. And the second one using annotation, which doesn't work, and I don't find the reason. I followed the samples of spring-mvc-test pretty much.</p>
<p><strong>Working</strong>:</p>
<pre><code>package com.company.web.api;
// imports
public class ApiTests {
@Test
public void testApiGetUserById() throws Exception {
ApplicationContext ctx = new ClassPathXmlApplicationContext("/com/company/web/api/ApiTests-context.xml");
UserManagementService userManagementService = (UserManagementService) ctx.getBean("userManagementService");
ApiUserManagementController apiUserManagementController = new ApiUserManagementController(userManagementService);
MockMvc mockMvc = standaloneSetup(apiUserManagementController).build();
// The actual test
mockMvc.perform(get("/api/user/0").accept(MediaType.APPLICATION_JSON)).andExpect(status().isOk());
}
}
</code></pre>
<p><strong>Failing</strong>, because <code>userManagementService</code> is null, not getting autowired:</p>
<pre><code>@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration // should default to ApiTests-context.xml in same package
public class ApiTests {
@Autowired
UserManagementService userManagementService;
private MockMvc mockMvc;
@Before
public void setup(){
// SetUp never gets called?!
}
@Test
public void testGetUserById() throws Exception {
// !!! at this point, userManagementService is still null - why? !!!
ApiUserManagementController apiUserManagementController
= new ApiUserManagementController(userManagementService);
mockMvc = standaloneSetup(apiUserManagementController).build();
// The actual test
mockMvc.perform(get("/api/user/0").accept(MediaType.APPLICATION_JSON)).andExpect(status().isOk());
}
}
</code></pre>
<p>Note that both test classes above should be using the same context configuration, and the userManagementService is defined in there.</p>
<p>ApiTests-context.xml:</p>

</code></pre>
<p>and the UserManagementService (interface) as well as UserManagementServiceImpl has the <code>@Service</code> annotation.</p>
<p>Two minor questions/observations: setup() never gets called, even though it has the @Before annotation. Furthermore, I noticed that my test methods don't get executed/recognized if they don't start with the name 'test', which is not the case though with all spring-mvc-test samples I saw.</p>

How to add title to the custom Dialog?
|
<p>How can i add title to this custom dialog??</p>
<p><img src="https://i.stack.imgur.com/luw1g.jpg" alt="enter image description here"></p>
<p>I have tried like this</p>
<pre><code>public void customDialog()
{
Dialog dialog=new Dialog(this);
dialog.requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
dialog.getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,R.string.app_name );
dialog.setContentView(R.layout.dialog_submit);
TextView edit_model=(TextView) dialog.findViewById(R.id.edit_model);
edit_model.setText(android.os.Build.DEVICE);
dialog.show();
}//end of custom dialog function
</code></pre>
<p>I have tried to set title like this too..<code>dialog.setTitle("Enter Details");</code> but this too didn't yielded any result. So how can i set title to this custom dialog??</p>
<p>This is my dialog_submit.xml file used for the custom dialog.</p>

CMake: create_symlink vs ln
|
<p>I have a macro to create links E.g.</p>
<pre><code>makeLink($BUILD_ROOT/lib somewhere/somelibrary.so makelinks)
</code></pre>
<p>The purpose of this is so that a completed build includes a directory structure analogous to a developers installation with <em>bin</em>, <em>include</em> & <em>lib</em> directories containing links to the actual products.</p>
<p><em>However, the purpose is not relevant to my question which is about create_symlink and not a meta-question about whether links should be used for this or any other purpose.</em></p>
<p>The macro can be implemented in several ways including:</p>
<pre><code>macro(makeLink src dest target)
add_custom_command(TARGET ${target} PRE_BUILD
COMMAND ln -sf ${src} ${dest} DEPENDS ${dest} COMMENT "mklink ${src} -> ${dest}")
endmacro()
</code></pre>
<p>or:</p>
<pre><code>macro(makeLink src dest target)
add_custom_command(TARGET ${target} PRE_BUILD
COMMAND ${CMAKE_COMMAND} -E create_symlink ${src} ${dest} DEPENDS ${dest} COMMENT "mklink ${src} -> ${dest}")
endmacro()
</code></pre>
<p>Now I understand the point of create_symlink is to be portable in case the platform doesn't understand links. However it seems to be functionally incomplete. There are several different use cases with <em>ln</em></p>
<ul>
<li>create a link whether the source exists yet or not</li>
<li>create a link only if the source exists</li>
<li>overwrite an existing link or not</li>
</ul>
<p>As far as I can see the cmake documentation under-specifies the behaviour (its actually: create the link if the destination doesn't exist and the source exists. Fail if the source doesn't exist)</p>
<p><a href="https://cmake.org/cmake/help/v3.2/manual/cmake.1.html" rel="nofollow noreferrer">https://cmake.org/cmake/help/v3.2/manual/cmake.1.html</a></p>
<p>This seems possibly to confuse many users who think it ought to work according to one and only one of the possibly use cases. E.g.</p>
<p><a href="https://cmake.org/Bug/view.php?id=14928" rel="nofollow noreferrer">https://cmake.org/Bug/view.php?id=14928</a>
<a href="https://cmake.org/Bug/print_bug_page.php?bug_id=4418" rel="nofollow noreferrer">https://cmake.org/Bug/print_bug_page.php?bug_id=4418</a></p>
<p><em>Given this why should anyone ever use create_symlink?
Wouldn't the sensible course be to incorporate support for all the common use cases (essentially by implementing a system portable wrapper to ln)?</em>
<strong>Is there a semi-standard .cmake file for this somewhere?</strong></p>
<p>Also is cmake really doing a recursive call to fork itself when you use cmake -E or does the parser recognise it as a special case. I suspect the latter as seems very fast (granted creating links this way would still seem fast) but if that's so why the unnecessarily verbose syntax?</p>
<hr />
<p>Note: I am not building the libraries as part of configure. <em>links</em> to libraries are created to support two things:</p>
<ul>
<li>linking programs that use the libraries in other sub-projects</li>
<li>running tests that use the libraries</li>
</ul>
<p>The libraries are not actually being built during the 'configure' stage. The links only need to be available just in time. This is part of a migration from a configure/make based build system to cmake/ninja. Its a largish project where a phased roll out of cmake is preferable to a big bang. It just so happens that in the existing system the links are made at configure time (though not used until build time).</p>

Pass parameter to subquery
|
<p>I'm using SSRS/SSDT in Visual Studio 2015 and SQL Server 2014. There's a bug that's been present for > 8 years where <a href="https://stackoverflow.com/questions/14466874/in-ssrs-why-do-i-get-the-error-item-with-same-key-has-already-been-added-wh">you can't select multiple columns from different tables that have the same name</a>. To get around this, I need to use a subquery. Every single answer I find rewrites the given query to remove the subquery, which would normally be great but <strong>is not applicable in this case</strong>. How do I pass a parameter to a subquery in SQL Server?</p>
<p>Column aliases do not work with this bug--Using <code>AS</code> returns an unknown column error on the "duplicate" columns even though it works with all others. The last two lines in the <code>SELECT</code> clause work because the values are being queried so the report can use them, but the remainder of the actual query doesn't use them.</p>
<p>Here's my current code (doesn't work because the subquery returns multiple rows).</p>
<pre><code>SELECT t.[Description],
t.RequestedCompletionDate,
t.CommitDate,
t.StatusId,
t.PriorityId,
p.ProjectNumber,
s.Name AS StatusDescription,
pr.Name AS PriorityDescription
FROM ProjectTask t
inner join Project p
on p.Id = t.ProjectId
inner join Project_TaskStatus s
on s.Id = t.StatusId
inner join Project_Priority pr
on pr.Id = t.PriorityId
WHERE t.Type = 'ET'
AND t.StatusId NOT IN (4,7)
AND
(
SELECT StatusId FROM Project
-- WHERE ?
)
NOT IN (3, 4)
ORDER BY t.PriorityId,
t.CommitDate,
t.RequestedCompletionDate
</code></pre>
<p>This is the code with aliases as requested in the comments. It throws an error:</p>
<pre><code>SELECT t.[Description],
t.RequestedCompletionDate,
t.CommitDate,
t.StatusId AS TaskStatusId,
t.PriorityId,
p.ProjectNumber,
p.StatusId AS ProjectStatusId,
s.Name AS StatusDescription,
pr.Name AS PriorityDescription
FROM ProjectTask t
inner join Project p
on p.Id = t.ProjectId
inner join Project_TaskStatus s
on s.Id = TaskStatusId
inner join Project_Priority pr
on pr.Id = t.PriorityId
WHERE t.Type = 'ET'
AND TaskStatusId NOT IN (4,7)
AND ProjectStatusId NOT IN (3,4)
ORDER BY t.PriorityId,
t.CommitDate,
t.RequestedCompletionDate
-- Invalid column name 'TaskStatusId'.
-- Invalid column name 'TaskStatusId'.
-- Invalid column name 'TaskStatusId'.
-- Invalid column name 'ProjectStatusId'.
-- Invalid column name 'ProjectStatusId'.
</code></pre>
<p>The ideal code is below, but it throws the error <code>An item with the same key has already been added</code>, which is the error that SSRS/SSDT throws when trying to return multiple columns of the same name.</p>
<pre><code>SELECT t.[Description],
t.RequestedCompletionDate,
t.CommitDate,
t.StatusId,
t.PriorityId,
p.ProjectNumber,
p.StatusId,
s.Name AS StatusDescription,
pr.Name AS PriorityDescription
FROM ProjectTask t
inner join Project p
on p.Id = t.ProjectId
inner join Project_TaskStatus s
on s.Id = t.StatusId
inner join Project_Priority pr
on pr.Id = t.PriorityId
WHERE t.Type = 'ET'
AND t.StatusId NOT IN (4,7)
AND p.StatusId NOT IN (3,4)
ORDER BY t.PriorityId,
t.CommitDate,
t.RequestedCompletionDate

MessageContext in SOAPHandler JAX-WS WebService
|
<p>I have a JAX-WS 2.2 WebService and I must take the IP Address of each client that communicate with it. I write a SOAP protocol handler but I can't see the addresses because the handlers doesn't contain this information and using the mimeheaders I can't also see this information. The code of my handler is the follow:</p>
<pre><code>public class AddressHandler implements SOAPHandler<SOAPMessageContext> {
private void takeIPAddress(SOAPMessageContext context) {
try {
SOAPMessage original = context.getMessage();
MimeHeaders mimeheaders = original.getMimeHeaders();
MimeHeader mimeheader = null;
Iterator<?> iter = mimeheaders.getAllHeaders();
for (; iter.hasNext();) {
mimeheader = (MimeHeader) iter.next();
System.out.println("name=" + mimeheader.getName() + ", value="
+ mimeheader.getValue());
}
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void close(MessageContext arg0) {
// TODO Auto-generated method stub
}
@Override
public boolean handleFault(SOAPMessageContext arg0) {
// TODO Auto-generated method stub
return false;
}
@Override
public boolean handleMessage(SOAPMessageContext context) {
takeIPAddress(context);
return true;
}
@Override
public Set<QName> getHeaders() {
// TODO Auto-generated method stub
return null;
}
}
</code></pre>
<p>Now I'm seeing that would be possible to see the addresses using the following code:</p>
<pre><code>SOAPMessageContext jaxwsContext = (SOAPMessageContext)wsContext.getMessageContext();
HttpServletRequest request = HttpServletRequest)jaxwsContext.get(SOAPMessageContext.SERVLET_REQUEST);
String ipAddress = request.getRemoteAddr();
</code></pre>
<p>But I can't import correctly the HttpServletRequest class. Do you have any ideas?</p>
<p><strong>UPDATE</strong></p>
<p>Thanks to A Nyar Thar, I've seen that exists another method to take address and I've implemented this in my code, that now is:</p>
<pre><code>private void takeIPAddress(SOAPMessageContext context) {
HttpExchange exchange = (HttpExchange)context.get("com.sun.xml.ws.http.exchange");
InetSocketAddress remoteAddress = exchange.getRemoteAddress();
String remoteHost = remoteAddress.getHostName();
System.out.println(remoteHost);
}
</code></pre>
<p>But the code execution create this error (where row 39 is where I do exchange.getRemoteAddress()):</p>
<pre><code>java.lang.NullPointerException

<p>I think that the real problem is that I don't know how take WebServiceContext from my class AddressHandler. Do you have ideas?</p>

How Do I Catch by FullyQualifiedErrorId in PowerShell?

<p>I have a script that creates new AD Objects (via New-ADObject, as it happens). If the object already exists, I need to catch and handle that. However, the exception type isn't nearly as explicit as the FullyQualifiedErrorId. Observe the below:</p>
<pre><code>> $Error[-1] | Format-List -Property * -Force
writeErrorStream : True

Why do we need to use import 'babel-polyfill'; in react components?
|
<p>I wonder if we user babel loader + all the presets, why do we need to include babel-polyfill anyway into our components? I just think that babel-loader should do all the job itself.</p>

css cursor using data-uri
|
<p>I'm trying to use custom png cursor using data uri but the cursor doesn't change.
I've tested on FF 17 which support png as custom cursor.
The same data uri work as a background image.</p>
<p>Am I using wrong syntax or maybe data-uri can't be used as a cursor image?</p>

<p>I'm at a loss for what the issue is. I already have /usr/share/tomcat-6/lib/postgresql-8.4-702.jdbc4.jar in place. Moving it to /WEB-INF/lib makes no difference. It seems to me that it can see the resource entry in WEB-INF/web.xml, but that it can't pull the details from META-INF/context.xml. Assigning a password there also seems to make no difference.</p>

SQL Query to return 24 hour, hourly count even when no values exist?
|
<p>I've written a query that groups the number of rows per hour, based on a given date range.</p>
<pre><code>SELECT CONVERT(VARCHAR(8),TransactionTime,101) + ' ' + CONVERT(VARCHAR(2),TransactionTime,108) as TDate,
COUNT(TransactionID) AS TotalHourlyTransactions
FROM MyTransactions WITH (NOLOCK)
WHERE TransactionTime BETWEEN CAST(@StartDate AS SMALLDATETIME) AND CAST(@EndDate AS SMALLDATETIME)
AND TerminalId = @TerminalID
GROUP BY CONVERT(VARCHAR(8),TransactionTime,101) + ' ' + CONVERT(VARCHAR(2),TransactionTime,108)
ORDER BY TDate ASC
</code></pre>
<p>Which displays something like this:</p>
<pre><code>02/11/20 07 4
02/11/20 10 1
02/11/20 12 4
02/11/20 13 1
02/11/20 14 2
02/11/20 16 3
</code></pre>
<p>Giving the number of transactions and the given hour of the day.</p>
<p>How can I display all hours of the day - from 0 to 23, and show 0 for those which have no values?</p>
<p>Thanks.</p>
<h2>UPDATE</h2>
<p>Using the tvf below works for me for one day, however I'm not sure how to make it work for a date range.</p>
<p>Using the temp table of 24 hours:</p>
<pre><code> -- temp table to store hours of the day
DECLARE @tmp_Hours TABLE ( WhichHour SMALLINT )
DECLARE @counter SMALLINT
SET @counter = -1
WHILE @counter < 23
BEGIN
SET @counter = @counter + 1
--print
INSERT INTO @tmp_Hours
( WhichHour )
VALUES ( @counter )
END
SELECT MIN(CONVERT(VARCHAR(10),[dbo].[TerminalTransactions].[TransactionTime],101)) AS TDate, [@tmp_Hours].[WhichHour], CONVERT(VARCHAR(2),[dbo].[TerminalTransactions].[TransactionTime],108) AS TheHour,
COUNT([dbo].[TerminalTransactions].[TransactionId]) AS TotalTransactions,
ISNULL(SUM([dbo].[TerminalTransactions].[TransactionAmount]), 0) AS TransactionSum
FROM [dbo].[TerminalTransactions] RIGHT JOIN @tmp_Hours ON [@tmp_Hours].[WhichHour] = CONVERT(VARCHAR(2),[dbo].[TerminalTransactions].[TransactionTime],108)
GROUP BY [@tmp_Hours].[WhichHour], CONVERT(VARCHAR(2),[dbo].[TerminalTransactions].[TransactionTime],108), COALESCE([dbo].[TerminalTransactions].[TransactionAmount], 0)
</code></pre>
<p>Gives me a result of:</p>
<pre><code>TDate WhichHour TheHour TotalTransactions TransactionSum
---------- --------- ------- ----------------- ---------------------
02/16/2010 0 00 4 40.00
NULL 1 NULL 0 0.00
02/14/2010 2 02 1 10.00
NULL 3 NULL 0 0.00
02/14/2010 4 04 28 280.00
02/14/2010 5 05 11 110.00
NULL 6 NULL 0 0.00
02/11/2010 7 07 4 40.00
NULL 8 NULL 0 0.00
02/24/2010 9 09 2 20.00
</code></pre>
<p>So how can I get this to group properly?</p>
<p>The other issue is that for some days there will be no transactions, and these days also need to appear.</p>
<p>Thanks.</p>

How to update MS Access Database (vb.net)
|
<p>I am created a journal program for an internship project and I am using a MS-Access Database. I am programming in <strong>VB.net</strong>. Now, I am trying to make it so that they can "Update" their journals, meaning that they click on their calendar date and it brings them to that journal if they have one for that date. If they have one for that date then it shows the title and journal text entry for that date. I want to make it so that any changes they have made to the journal (editing the textbox fields) are also changed in the database when they click the update button. Here's what i have so far</p>
<pre><code> Private Sub COE_JournalBtn_Click(sender As System.Object, e As System.EventArgs) Handles COE_JournalBtn.Click
If DateTimePicker1.Value <> Nothing Then
If TitleTxt.Text <> "" Then
If JournalTextRtxt.Text <> "" Then
myConnection.Open()
Dim DatePicked As String = DateTimePicker1.Value
Dim cmd As OleDbCommand
Dim str As String
Try
MyJournalTitle = TitleTxt.Text
MyJournalText = JournalTextRtxt.Text
str = "UPDATE Journals SET JournalTitle='" & MyJournalTitle & "', JournalText='" & MyJournalText & "' WHERE JournalDate=" & DatePicked
cmd = New OleDbCommand(str, myConnection)
cmd.ExecuteNonQuery()
myConnection.Close()
Catch ex As Exception
MessageBox.Show("There was an error processing your request. Please try again." & vbCrLf & vbCrLf & _
"Original Error:" & vbCrLf & vbCrLf & ex.ToString, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
myConnection.Close()
End Try
myConnection.Close()
End If
End If
End If
End Sub
</code></pre>
<p>Now my update string by itself is</p>
<pre><code>"UPDATE Journals SET JournalTitle='" & MyJournalTitle & "', JournalText='" & MyJournalText & "' WHERE JournalDate=" & DatePicked
</code></pre>
<p>Now, what happens, is absolutely nothing. No errorboxes come up. No messageboxes appear. The program doesn't freeze. And the database remains unchanged. What am I doing wrong? Is there an error in my code or something missing? Please help me because I really want to figure this out and i've been looking everywhere for a solution in VB.net and cannot find one that applies to me being that I am using MS-Access and NOT SQL.</p>
<p>Thanks in advance,
Richard Paulicelli</p>

</code></pre>
<p>Some tools are able to install, others are not. I can't do anything about the <code>Not a git repository</code> error because it's an automated process and I'm not the one typing the git commands.</p>
<p>I tried installing the tools separately in PowerShell and I get the same errors. My go directory is created (in <code>%USERPROFILE%\go</code>) and the <code>GOPATH</code> is set correctly.</p>
<p>Any ideas ?</p>
