364,794 | <p>My first instinct is to say each key is an object, and has a hash code, which is what is used to determine if a duplicate is being inserted. However, I can't find anything to back that up for sure. Can someone provide a link that says that, or provide the real answer here? Thanks!</p>

364,809 | <p>I want to gather data from different data servers located in Europe and Asia. Rather than running a plain data query task that will clog up the undersea network I am thinking of a couple of machines that will be available for me at the local sites.</p>
<p>I am thinking to design the master package so that I can:</p>
<ol>
<li>run remote setup tasks</li>
<li>launch the data collection package locally using psexec dtexec ...</li>
<li>get the data locally stored in multiple raw file (1 for each type of data)</li>
<li>zipped and pulled back</li>
<li>unzipped and bulkuploaded to local server</li>
</ol>
<p>Data collection is handled through custom script source since the data is available through a weird class library.</p>
<p>Tasks can fail unpredictably. If a particular type of data is successfully captured while the others fail for a particular location, I don't want to run it again.</p>
<p>How can I simplify this design if possible and make it more robust?</p>

364,825 | <p>I have a query to the effect of</p>
<pre><code>SELECT t3.id, a,bunch,of,other,stuff FROM t1, t2, t3
WHERE (associate t1,t2, and t3 with each other)
GROUP BY t3.id
LIMIT 10,20
</code></pre>
<p>I want to know to many total rows this query would return without the LIMIT (so I can show pagination information).</p>
<p>Normally, I would use this query:</p>
<pre><code>SELECT COUNT(t3.id) FROM t1, t2, t3
WHERE (associate t1,t2, and t3 with each other)
GROUP BY t3.id
</code></pre>
<p>However the GROUP BY changes the meaning of the COUNT, and instead I get a set of rows representing the number of unique t3.id values in each group.</p>
<p>Is there a way to get a count for the total number of rows when I use a GROUP BY? I'd like to avoid having to execute the entire query and just counting the number of rows, since I only need a subset of the rows because the values are paginated. I'm using MySQL 5, but I think this pretty generic.</p>

364,832 | <p>So, I have the following rows in the DB:</p>
<p>1 | /users/</p>
<p>2 | /users/admin/</p>
<p>3 | /users/admin/*</p>
<p>4 | /users/admin/mike/</p>
<p>5 | /users/admin/steve/docs/</p>
<p>The input URL is <strong>/users/admin/steve/</strong>, and the goal is to find the URL match from the DB.</p>
<p>I want to return #3 as the correct row, since the wildcard "*" specifies that anything can go in place of the asterisk. What would be the most efficient method for doing this?</p>
<p><strong>Here's my initial thoughts, but I'm sure they could be improved upon:</strong></p>
<ol>
<li>Make a query to see if there's an exact URL match</li>
<li>If no matches, then retrieve all rows with "*" as the last character, in reverse order (so the more specific URLs take precedence)</li>
<li>For each row, if it (minus the "*") matches the input URL, then return it</li>
<li>If nothing is found, then we're SOL</li>
</ol>

364,842 | <p>I've got a Perl script that needs to execute another Perl script. This second script can be executed directly on the command line, but I need to execute it from within my first program. I'll need to pass it a few parameters that would normally be passed in when it's run standalone (the first script runs periodically, and executes the second script under a certain set of system conditions).</p>
<p>Preliminary Google searches suggest using backticks or a system() call. Are there any other ways to run it? (I'm guessing yes, since it's Perl we're talking about :P ) Which method is preferred if I need to capture output from the invoked program (and, if possible, pipe that output as it executes to stdout as though the second program were invoked directly)?</p>
<p>(Edit: oh, <strong>now</strong> SO suggests some related questions. <a href="https://stackoverflow.com/questions/109124/run-external-process-from-perl-capture-stderr-stdout-and-the-process-exit-code">This one</a> is close, but not exactly the same as what I'm asking. The second program will likely take an hour or more to run (lots of I/O), so I'm not sure a one-off invocation is the right fit for this.)</p>

364,925 | <p>Say I have a git repository and I've been working on master, can I retroactively create a branch. For example:</p>
<p>A - B - C - A1 - D - A2 - E</p>
<p>I want to make it look like this:</p>
<pre><code>A - A1 - A2
\ \
B - C - D - E
</code></pre>
<p>The specific use case is when I've cherry-picked a bunch of commits into an old version branch and it needs to go into multiple older versions and I don't want to repeat the cherry-pick on all those revision.</p>
<p>Essentially it's something that would have been good as a feature or topic branch in the first place but wasn't created like that.</p>

364,936 | <p>Does anyone have any good suggestions for creating a Pipe object in Java which <em>is</em> both an InputStream and and OutputStream since Java does not have multiple inheritance and both of the streams are abstract classes instead of interfaces?</p>
<p>The underlying need is to have a single object that can be passed to things which need either an InputStream or an OutputStream to pipe output from one thread to input for another.</p>

364,946 | <p>I am giving link of a pdf file on my web page for download, like below</p>
<pre><code><a href="myfile.pdf">Download Brochure</a>
</code></pre>
<p>The problem is when user clicks on this link then</p>
<ul>
<li>If the user have installed Adobe Acrobat, then it opens the file in the same browser window in Adobe Reader.</li>
<li>If the Adobe Acrobat is not installed then it pop-up to the user for Downloading the file.</li>
</ul>
<p>But I want it always pop-up to the user for download, irrespective of "Adobe acrobat" is installed or not.</p>
<p>Please tell me how i can do this?</p>

364,952 | <p>I would like to manipulate the HTML inside an iframe using jQuery.</p>
<p>I thought I'd be able to do this by setting the context of the jQuery function to be the document of the iframe, something like:</p>
<pre><code>$(function(){ //document ready
$('some selector', frames['nameOfMyIframe'].document).doStuff()
});
</code></pre>
<p>However this doesn't seem to work. A bit of inspection shows me that the variables in <code>frames['nameOfMyIframe']</code> are <code>undefined</code> unless I wait a while for the iframe to load. However, when the iframe loads the variables are not accessible (I get <code>permission denied</code>-type errors).</p>
<p>Does anyone know of a work-around to this?</p>

364,963 | <p>I have an a aspx page, but all content is generated by hands(yes I know that I need to make a handler, I have another question)</p>
<p>I want to cache output in client browser. Problem is that it's cached only for one query.</p>
<pre><code> public static void ProceedCaching(string etag, string lastModify, string response, HttpResponse Response,
HttpRequest Request)
{
Response.AddHeader("ETag", "\"" + etag + "\"");
Response.AddHeader("Last-Modified", lastModify);
Response.AppendHeader("Cache-Control", "Public");
Response.AppendHeader("Expires",
DateTime.Now.AddMinutes(1).ToUniversalTime().ToString("r",DateTimeFormatInfo.InvariantInfo));
string ifModified = Request.Headers["If-Modified-Since"];
if (!string.IsNullOrEmpty(ifModified))
{
if (ifModified.Contains(";"))
ifModified = ifModified.Remove(ifModified.IndexOf(';'));
}
string incomingEtag = Request.Headers["If-None-Match"];
if (String.Compare(incomingEtag, etag) == 0 || string.Compare(ifModified, lastModify) == 0)
{
Response.StatusCode = 304;
Response.End();
}
Response.Write(response);
Response.End();
}
</code></pre>
<p>it's become preaty messy.
As I said it's cached only once. After recevieng HTTP 304 browser will send clean request without caching information(etag, lastmodified).
Have any ideas? </p>

364,985 | <p>I need to find the smallest power of two that's greater or equal to a given value. So far, I have this:</p>
<pre><code>int value = 3221; // 3221 is just an example, could be any number
int result = 1;
while (result < value) result <<= 1;
</code></pre>
<p>It works fine, but feels kind of naive. Is there a better algorithm for that problem?</p>
<p>EDIT. There were some nice Assembler suggestions, so I'm adding those tags to the question.</p>

<p>The Smarty site says it should be the same, however, I was not able to find anyone doing real benchmarking to prove the statement right or wrong.</p>
<p>Did anyone do some benchmarking of Smarty vs plain PHP? Or maybe come across some resources on such tests?</p>

365,006 | <p>I have set up a version control system using <strong>TortoiseSVN</strong> at my home to manage my pet projects, school projects etc...and it works locally.</p>
<p>Now I need to be able to access my code repository remotely, like from school, so that I will be able to update the source at school from the repository, and commit it again once I have finished working on it.</p>
<p>The question is, <strong>how can I connect to my repository remotely</strong> ? What ports do I need to open on my router for example?</p>
<p>Also, I cannot install the Tortoise client at school, so I will need some other <em>portable</em> application that does this task, be it GUI or <a href="http://en.wikipedia.org/wiki/Command-line_interface" rel="nofollow noreferrer">CLI</a>.</p>

365,028 | <p>I'm not a JS guy so I'm kinda stumbling around in the dark. Basically, I wanted something that would add a link to a twitter search for @replies to a particular user while on that person's page. </p>
<p>Two things I am trying to figure out:</p>
<ol>
<li>how to extract the user name from the page so that I can construct the right URL. ie. if I am on <a href="http://twitter.com/ev" rel="nofollow noreferrer">http://twitter.com/ev</a> , I should get "ev" back. </li>
<li>how to manipulate the DOM to insert things at the right place</li>
</ol>
<p>Here's the HTML fragment I'm targetting:</p>
<pre><code><ul id="tabMenu">
<li>
<a href="/ev" id="updates_tab">Updates</a> </li>
<li>
<a href="/ev/favourites" id="favorites_tab">Favorites</a> </li>
</ul>
</code></pre>
<p>And here is the script (so far):</p>
<pre><code>// ==UserScript==
// @name Twitter Replies Search
// @namespace http://jauderho.com/
// @description Find all the replies for a particular user
// @include http://twitter.com/*
// @include https://twitter.com/*
// @exclude http://twitter.com/home
// @exclude https://twitter.com/home
// @author Jauder Ho
// ==/UserScript==
var menuNode = document.getElementById('tabMenu');
if (typeof(menuNode) != "undefined" && menuNode != null)
{
var html = [];
html[html.length] = '<li>';
html[html.length] = '<a href="http://search.twitter.com/search?q=to:ev" class="section-links" id="replies_search_tab">@Replies Search</a>';
html[html.length] = '</li>';
// this is obviously wrong
var div = document.createElement('div');
div.className = 'section last';
div.innerHTML = html.join('');
followingNode = menuNode.parentNode;
followingNode.parentNode.insertBefore(div, followingNode);
}

365,029 | <p>I was reading a book on templates and found the following piece of code:</p>
<pre><code>template <template <class> class CreationPolicy>
class WidgetManager : public CreationPolicy<Widget>
{
...
void DoSomething()
{
Gadget* pW = CreationPolicy<Gadget>().Create();
...
}
};
</code></pre>
<p>I didn't get the nested templates specified for the CreationPolicy (which is again a template). What is the meaning of that weird looking syntax?</p>

365,045 | <p>I have a database (NexusDB (supposedly SQL-92 compliant)) which contains and Item table, a Category table, and a many-to-many ItemCategory table, which is just a pair of keys. As you might expect, Items are assigned to multiple categories. </p>
<p>I am wanting to all the end user to select all items which are </p>
<p>ItemID | CategoryID<br>
--------------------------------<br>
01 | 01<br>
01 | 02<br>
01 | 12<br></p>
<p>02 | 01<br>
02 | 02<br>
02 | 47<br></p>
<p>03 | 01<br>
03 | 02<br>
03 | 14<br>
etc...<br></p>
<p>I want to be able to select all ItemID's that are assigned to Categories X, Y, and Z but NOT assigned to Categories P and Q. </p>
<p>For the example data above, for instance, say I'd like to grab all Items assigned to Categories 01 or 02 but NOT 12 (yielding Items 02 and 03). Something along the lines of:</p>
<p>SELECT ItemID WHERE (CategoryID IN (01, 02)) </p>
<p>...and remove from that set SELECT ItemID WHERE NOT (CategoryID = 12)</p>
<p>This is probably a pretty basic SQL question, but it's stumping me at the moment. Any help w/b appreciated.</p>

365,048 | <p>why this is happen ?</p>
<p>When u create abstract class in c++ Ex: <strong>Class A</strong> (which has a pure virtual function)
after that <strong>class B</strong> is inherited from class <strong>A</strong> </p>
<p>And if <strong>class A</strong> has constructor called <strong>A()</strong>
suppose i created an <strong>Object</strong> of <strong>class B</strong> then the compiler initializes the base class first i.e.<strong>class A</strong> and then initialize the <strong>class B</strong> Then.......?</p>
<p>First thing is we can not access a constructor of any class without an Object then how it is initialize the constructor of abstract class if we can not create an object of abstract class .</p>

Martin v. Löwis' answer is good, and works for a full logout but it does not work for a 'fast user switching' event like pressing win+L which is what I really need it for.

365,086 | <p>How can I project the row number onto the linq query result set.</p>
<p>Instead of say:</p>

select new ScoreWithRank()

365,155 | <p>I want a simple tutorial to show me how to load a yaml file and parse the data. Expat style would be great but any solution that actually shows me the data in some form would be useful.</p>
<p>So far I ran multiple tests in the <code>yaml-0.1.1</code> source code for C and I either get an error, no output whatsoever, or in the <code>run-emitter.c</code> case. It reads in the yaml file and prints it to <code>STDOUT</code>, it does not produce the text via <code>libyaml</code> functions/structs. In the cases with an error I don't know if it was because the file was bad or my build is incorrect (I didn't modify anything...) The file was copied from yaml.org</p>
<p>Can anyone point me to a tutorial? (I googled for at least 30 minutes reading anything that looked relevant) or a name of a lib that has a good tutorial or example. Maybe you can tell me which <code>libyaml</code> test loads in files and does something with it or why I got errors. This document does not explain how to <em>use</em> the file--only how to load it:</p>

365,168 | <p>Since I kicked off the process of inserting 7M rows from one table into two others, I'm wondering now if there's a faster way to do this. The process is expected to finish in an hour, that's 24h of processing.</p>
<p>Here's how it goes:</p>
<p>The data from this table</p>
<pre><code>RAW (word VARCHAR2(4000), doc VARCHAR2(4000), count NUMBER);
</code></pre>
<p>should find a new home in two other cluster tables T1 and T2</p>
<pre><code>CREATE CLUSTER C1 (word VARCHAR2(4000)) SIZE 200 HASHKEYS 10000000;
CREATE CLUSTER C2 (doc VARCHAR2(4000)) SIZE 200 HASHKEYS 10000000;
T1 (word VARCHAR2(4000), doc VARCHAR2(4000), count NUMBER) CLUSTER C1(word);
T2 (doc VARCHAR2(4000), word VARCHAR2(4000), count NUMBER) CLUSTER C2(doc);
</code></pre>
<p>through Java inserts with manual commit like this</p>
<pre><code>stmtT1 = conn.prepareStatement("insert into T1 values(?,?,?)");
stmtT2 = conn.prepareStatement("insert into T2 values(?,?,?)");
rs = stmt.executeQuery("select word, doc, count from RAW");
conn.setAutoCommit(false);
while (rs.next()) {
word = rs.getString(1);
doc = rs.getString(2);
count = rs.getInt(3);
if (commitCount++==10000) { conn.commit(); commitCount=0; }
stmtT1.setString(1, word);
stmtT1.setString(2, doc);
stmtT1.setInt(3, count);
stmtT2.setString(1, doc);
stmtT2.setString(2, word);
stmtT2.setInt(3,count);
stmtT1.execute();
stmtT2.execute();
}
conn.commit();
</code></pre>
<p>Any ideas?</p>

<p>I have tried everything I can think of. I even instantiated another datacontext in the method and after the instance came back from ExecuteDynamicInsert with the id, tried to add it, and I get timeout errors.</p>

365,224 | <p>Pour in your posts. I'll start with a couple, let us see how much we can collect.</p>
<p>To provide inline event handlers like</p>
<pre><code>button.Click += (sender,args) =>
{
};
</code></pre>
<p>To find items in a collection</p>
<pre><code> var dogs= animals.Where(animal => animal.Type == "dog");
</code></pre>
<p>For iterating a collection, like</p>
<pre><code> animals.ForEach(animal=>Console.WriteLine(animal.Name));
</code></pre>
<p>Let them come!!</p>

<p>Is this normal behavior and is it possible to gracefully abort instead of (what looks like) a sudden abrupt abort?</p>
<h2>Update</h2>
<p>So far it the common census that it's <a href="http://msdn.microsoft.com/en-us/library/system.web.httpresponse.end.aspx" rel="noreferrer">by design</a>. So i'm wondering if it's possible we could take this question and see if we could tweak the code to make it not feel like we're ending the thread <em>prematurely</em> and gracefully exit ... Possible? Code examples?</p>

<li>call the external <code>grep</code> through an <code>open()</code> command</li>
<li><code>open()</code> the file directly and use a <code>while</code> loop and an <code>if ($line =~ m/regex/)</code>?</li>

365,284 | <p>When you rotate an image using canvas, it'll get cut off - how do I avoid this? I already made the canvas element bigger then the image, but it's still cutting off the edges.</p>
<p>Example:</p>
<pre><code><html>
<head>
<title>test</title>
<script type="text/javascript">
function startup() {
var canvas = document.getElementById('canvas');
var ctx = canvas.getContext('2d');
var img = new Image();
img.src = 'player.gif';
img.onload = function() {
ctx.rotate(5 * Math.PI / 180);
ctx.drawImage(img, 0, 0, 64, 120);
}
}
</script>
</head>
<body onload='startup();'>
<canvas id="canvas" style="position: absolute; left: 300px; top: 300px;" width="800" height="800"></canvas>

365,339 | <p>We currently send an email notification in plain text or html format. Our environment is C#/.NET/SQL Server.</p>
<p>I'd like to know if anyone recommends a particular solution. I see two ways of doing this:</p>
<ul>
<li>dynamically convert current email to pdf using a third party library and sending the pdf as an attachment</li>
</ul>
<p>or </p>
<ul>
<li>use SSRS to allow users to export pdf report (could eventually have SSRS push reports)</li>
</ul>
<p>I'm open to third party libraries (especially if they are open source and free). It seems that SSRS is the simplest and easiest way to go. Anyone have any tips?</p>

365,352 | <p>It is not uncommon for me (or likely anyone else) to have a list of objects I need to iterate through and then interact with a list of properties. I use a nested loop, like this:</p>
<pre><code>IList<T> listOfObjects;
IList<TProperty> listOfProperties;
foreach (T dataObject in listOfObjects)
{
foreach (TProperty property in listOfProperties)
{
//do something clever and extremely useful here
}
}
</code></pre>
<p>Is this the time and performance tested pattern for this problem? Or is there something more performant, more elegant, or just plain fun (while still being readable and maintainable of course)?</p>
<p>The code above doesn't make me smile. Can someone please help bring some joy to my loop?</p>
<p>Thank you!</p>
<p>Update: I use the term "nerd" in a most positive sense. As part of the wikipedia definition puts it "that refers to a person who passionately pursues intellectual activities". By "code nerd" I mean someone who is concerned about continually improving oneself as a programmer, finding new, novel, and elegant ways of coding that are fast, maintainable, and beautiful! They rejoice to move out of VB6 and want smart people to critique their code and help them smartify themselves. (Note: they also like to make new words that end in -ify).</p>
<p>Final note:</p>
<p>Thank you to Dave R, Earwicker, and TheSoftwareJedi for sending me down the Linq path. It is just the sort of happy code I was looking for!</p>

365,353 | <ol>
<li>In WordPress, how do I hide a Page?</li>
<li>How do I then reimplement it as a DIV, let's say, on another Page?</li>
</ol>
<p><strong>Context</strong></p>
<p>I'm trying to get some year-end tax write-offs here for my freelance business, and so I'm donating WordPress sites to churches. Now, unfortunately I'm finding that several pastors don't understand computers that well, and even though WordPress is fairly easy to tech guys like you and me, they get a bit confused. Therefore, I commented out Posts, Comments, Plugins, Widgets, Users, Design, and left nothing but Pages (New, Edit, Delete) and Media Gallery. I then took a theme that showed the Pages as tabs at the top like a normal website.</p>
<p>My hope is to call a particular page like Sidebar1 as its title. However, instead of this being displayed as a tab, it will be hidden. Then, it will be reimplemented as a DIV inside the page titled Home. If the pastor accidentally deletes Sidebar1, all he has to do is recreate it again and poof it reappears.</p>
<p>This doesn't deal with the Wordpress website, but the Wordpress installation.</p>
<p>I've changed the admin -- I just need to change the front-end.</p>
<p>I could figure this out on my own, but in the interest of time I wondered if someone had already done this?</p>
<p>Your help could help me get this done just in time for Christmas for some area churches here. Thank you.</p>

365,370 | <p>I am currently using TcpListener to address incoming connections, each of which are given a thread for handling the communication and then shutdown that single connection. Code looks as follows:</p>
<pre><code>TcpListener listener = new TcpListener(IPAddress.Any, Port);
System.Console.WriteLine("Server Initialized, listening for incoming connections");
listener.Start();
while (listen)
{
// Step 0: Client connection
TcpClient client = listener.AcceptTcpClient();
Thread clientThread = new Thread(new ParameterizedThreadStart(HandleConnection));
clientThread.Start(client.GetStream());
client.Close();
}
</code></pre>
<p>The <code>listen</code> variable is a boolean that is a field on the class. Now, when the program shuts down I want it to stop listening for clients. Setting listen to <code>false</code> will prevent it from taking on more connections, but since <code>AcceptTcpClient</code> is a blocking call, it will at minimum take the next client and THEN exit. Is there any way to force it to simply break out and stop, right then and there? What effect does calling listener.Stop() have while the other blocking call is running?</p>

365,371 | <p>I can't figure out how to achieve the following layout with CSS (probably because I don't actually know CSS).</p>
<p>I have a bunch of divs like this:</p>
<pre><code><div class="right"> <p>1</p> </div>
<div class="left"> <p>2</p> </div>
<div class="left"> <p>3</p> </div>
<div class="left"> <p>4</p> </div>
<div class="right"> <p>5</p> </div>
<div class="right"> <p>6</p> </div>
</code></pre>
<p>(not the real contents)</p>
<p>Now I want the layout to look like two equal columns of divs, with the "right" ones on the right, and the "left" ones on the left, thus:</p>
<pre><code>2 1
3 5
4 6
</code></pre>
<p>[<strong>Edit: In a previous version of this question I had textareas inside the divs, and the divs all had different names like "one" and "xyz".</strong>]
I tried something like</p>
<pre><code>div.right { width:50%; float:right; clear:right; }
div.left { width:50%; float:left; clear:left;}
</code></pre>
<p>but it doesn't quite work: It produces something like:</p>
<pre><code>2 1
3
4 5
6
</code></pre>
<p>(without the "clear"s, it blithely produces </p>
<pre><code>2 1
3 4
6 5
</code></pre>
<p>which is not what is wanted).</p>
<p>It is apparent that it can be made to work if the divs are ordered differently, but I'd like not to do that (because these divs are generated dynamically if the browser has Javascript, and I don't want to change the actual order that is displayed in the absence of Javascript, for semantic reasons). Is it still possible to achieve the layout I want?</p>
<p>[For what it's worth, I'm willing to have it not work on IE or older versions of other browsers, so if there is a solution that works only on standards-compliant browsers, that's okay :-)]</p>

365,376 | <p>I use a basic Post to send data to a Django server.</p>
<p>The data consists of a base64 encoded 640*380 PNG image dynamically created by the flex
component.</p>
<pre><code><mx:HTTPService id="formSend" showBusyCursor="true"
useProxy="false" url="http://127.0.0.1/form/"
method="POST" result="formSentConfirmation(event)" fault="formSendingFailed(event)"/>
private function sendForm(url:String, message:String, meteo:Number):void {
formSend.url = url;
var params:Object = { message: message, image_data: getEncodedImage() };
snapButton.label = "sending ...";
formSend.send(params);
}
</code></pre>
<p>On the server side i can see that the data is in the request.POST
not in request.FILES. That means the image is not send as a File with multiencode HTTP.</p>
<ol>
<li><p>Will i get into trouble on a real server ? since the limit is 200k for urlencoded POST var.</p></li>
<li><p>How to make HTTPservice send the data as a file?</p></li>
<li><p>Any other solutions?</p></li>
</ol>
<p>Thanks</p>

365,380 | <p>I was wondering if InnoDB would be the best way to format the table? The table contains one field, primary key, and the table will get 816k rows a day (est.). This will get very large very quick! I'm working on a file storage way (would this be faster)? The table is going to store ID numbers of Twitter Ids that have already been processed?</p>
<p>Also, any estimated memory usage on a <code>SELECT min('id')</code> statement? Any other ideas are greatly appreciated!</p>

365,382 | <p>How do you rotate an image with the canvas html5 element from the bottom center angle?</p>
<pre><code><html>
<head>
<title>test</title>
<script type="text/javascript">
function startup() {
var canvas = document.getElementById('canvas');
var ctx = canvas.getContext('2d');
var img = new Image();
img.src = 'player.gif';
img.onload = function() {
ctx.translate(185, 185);
ctx.rotate(90 * Math.PI / 180);
ctx.drawImage(img, 0, 0, 64, 120);
}
}
</script>
</head>
<body onload='startup();'>
<canvas id="canvas" style="position: absolute; left: 300px; top: 300px;" width="800" height="800"></canvas>
</body>
</html>
</code></pre>
<p>Unfortunately this seems to rotate it from the top left angle of the image. Any idea?</p>
<p>Edit: in the end the object (space ship) has to rotate like a clock pointer, as if it is turning right/left.</p>

365,391 | <p>I'm trying to use an excel VB macro to download excel files from a membership password-protected site. I am using the "InternetExplorer" object to open a browser window, log-in and browse to the correct page, then scanning for the links I want in the page. Using the Workbooks.Open(URLstring) doesn't work because Excel isn't logged. Instead of the actual file, it opens the html page asking for the log-in.</p>
<p>My preference would be to use the VB macro to automate the right-click "save target as" event in internet explorer on the correct link, but I don't know exactly how to do this.</p>

365,424 | <p>I've written an Apache module in C. Under certain conditions, I can get it to segfault, but I have no idea as to why. At this point, it could be my code, it could be the way I'm compiling the program, or it could be a bug in the OS library (the segfault happens during a call to dlopen()).</p>
<p>I've tried running through GDB and Valgrind with no success. GDB gives me a backtrace into the dlopen() system call that appears meaningless. In Valgrind, the bug actually seems to disappear or at least become non-reproducible. On the other hand, I'm a total novice when it comes to these tools.</p>
<p>I'm a little new to production quality C programming (I started on C many years ago, but have never worked professionally with it.) What is the best way for me to go about learning the ropes of debugging programs? What other tools should I be investigating? In summary, how do you figure out how to tackle new bug challenges?</p>
<p>EDIT:
Just to clarify, I want to thank Sydius's and dmckee's input. I had taken a look at Apache's guide and am fairly familiar with dlopen (and dlsym and dlclose). My module works for the most part (it's at about 3k lines of code and, as long as I don't activate this one section, things seem to work just fine.)</p>
<p>I guess this is where my original question comes from - I don't know what to do next. I know I haven't used GDB and Valgrind to their full potential. I know that I may not be compiling with the exact right flags. But I'm having trouble figuring out more. I can find beginner's guides that tell me what I already know, and man pages that tell me more than I need to know but with no guidance.</p>

365,427 | <p>I have problems with Boost.Spirit parsing a string. </p>
<p>The string looks like </p>
<pre><code>name1 has this and that.\n
name 2 has this and that.\n
na me has this and that.\n
</code></pre>
<p>and I have to extract the names. The text "has this and that" is always the same but the name can consist of spaces therefore I can't use graph_p. </p>
<p>1) How do I parse such a string?</p>
<p>Since the string has several lines of that format I have to store the names in a vector. </p>
<p>I used something like </p>
<pre><code>std::string name;
rule<> r = *graph_p[append(name)];
</code></pre>
<p>for saving one name but </p>

365,458 | <p>Is there a way to identify at run-time of an executable is being run from within valgrind? I have a set of C++ unit tests, and one of them expects <code>std::vector::reserve</code> to throw <code>std::bad_alloc</code>. When I run this under valgrind, it bails out completely, preventing me from testing for both memory leaks (using valgrind) and behavior (expecting the exception to be thrown).</p>
<p>Here's a minimal example that reproduces it:</p>
<pre><code>#include <vector>
int main()
{
size_t uint_max = static_cast<size_t>(-1);
std::vector<char> v;
v.reserve(uint_max);
}
</code></pre>
<p>Running valgrind, I get this output:</p>
<pre><code>Warning: silly arg (-1) to __builtin_new()
new/new[] failed and should throw an exception, but Valgrind
cannot throw exceptions and so is aborting instead. Sorry.
at 0x40192BC: VALGRIND_PRINTF_BACKTRACE (valgrind.h:319)
by 0x401C823: operator new(unsigned) (vg_replace_malloc.c:164)
by 0x80487BF: std::vector<char, std::allocator<char> >::reserve(unsigned) new_allocator.h:92)
by 0x804874D: main (vg.cxx:6)
</code></pre>
<p>I'd like to modify my unit test to simply skip the offending code when it's being run from within valgrind. Is this possible?</p>

365,472 | <p>I get the above error whenever I try and use ActionLink ? I've only just started playing around with MVC and don't really understand what it's problem is with the code (below):</p>
<pre><code><%= Html.ActionLink("Lists", "Index", "Lists"); %>
</code></pre>
<p>This just seems to be a parsing issue but it only happens when I run the page. The application builds perfectly fine, so I really don't get it because the error is a compilation error? If I take line 25 out it will happen on the next line instead...</p>

365,487 | <p>Everyday I receive thousands of emails and I want to parse the content/body of these emails to load them into a database.</p>
<p>My problem is that nowadays I am parsing the email body manually and I would like to change the logic to a <strong>Regular Expression in C#.</strong></p>
<p>Here is the body of the emails:</p>

<p>I need to extract the text in bold and I thought a RegEx is what I need for this...</p>

365,489 | <p>My company is about to hire <strong>.NET developers</strong>. We work on a variety of .NET platforms: ASP.NET, Compact Framework, Windowsforms, Web Services. I'd like to compile a list/catalog of good questions, a kind of minimum standard to see if the applicants are experienced. So, my question is:</p>
<p><strong>What questions</strong> do you think should a good <strong>.NET programmer be able to respond</strong>?</p>
<p>I'd also see it as a <strong>checklist</strong> for myself, in order to see where my own deficits are <em>(there are many...)</em>.</p>
<p><img src="https://i.imgur.com/Xo2yI.png" alt="alt text"></p>
<p>*UPDATE: It want to make clear that we're not testing only for .NET knowledge, and that problem solving capabilities and general programming skills are even more important to us. </p>

365,495 | <p>I have been a .net developer for the past three yrs. Just curious to know about the network security field. What kind of work does the developers working in these area do? I really have not much idea about network security but what my understanding is these people are involved in securing network, preventing attacks on network as obvious. Could any one please give me some details about this field and also what does it take to move to this field.</p>

365,496 | <p>I have an update query being run by a cron task that's timing out. The query takes, on average, five minutes to execute when executed in navicat.</p>
<p>The code looks roughly like this. It's quite simple:</p>
<pre><code>// $db is a mysqli link
set_time_limit (0); // should keep the script from timing out
$query = "SLOW QUERY";
$result = $db->query($query);
if (!$result)
echo "error";
</code></pre>
<p>Even though the script shouldn't timeout, the time spent waiting on the sql call still seems to be subject to a timeout.</p>
<p>Is there an asynchronous call that can be used? Or adjust the timeout?</p>
<p>Is the timeout different because it's being called from the command line rather than through Apache?</p>
<p>Thanks</p>

365,603 | <p>When viewing a webpage, I would like to copy a selection of text with its html formatting in one piece.
Meaning if some text is in bold and blue, I want the tool to create a style or class in the html which makes the text blue. Everything is contained in the produced html.</p>
<p>I have downloaded a similar plugin but the classes definitions are still external which means I have to get them separately. A non technical user would be at a loss here. I want the user to be able to copy and paste to a new webpage and that page just just works properly because the html copied contains everything.</p>
<p>This doesn't have to be a FF plugin. It could be IE or a Windows app.</p>

365,615 | <p>In C#/VB.NET/.NET, which loop runs faster, <code>for</code> or <code>foreach</code>?</p>
<p>Ever since I read that a <code>for</code> loop works faster than a <code>foreach</code> loop a <a href="https://learn.microsoft.com/previous-versions/dotnet/articles/ms973839(v=msdn.10)" rel="noreferrer">long time ago</a> I assumed it stood true for all collections, generic collections, all arrays, etc.</p>
<p>I scoured Google and found a few articles, but most of them are inconclusive (read comments on the articles) and open ended.</p>
<p>What would be ideal is to have each scenario listed and the best solution for the same.</p>
<p>For example (just an example of how it should be):</p>
<ol>
<li>for iterating an array of 1000+
strings - <code>for</code> is better than <code>foreach</code></li>
<li>for iterating over <code>IList</code> (non generic) strings - <code>foreach</code> is better
than <code>for</code></li>
</ol>
<p>A few references found on the web for the same: </p>
<ol>
<li><a href="https://learn.microsoft.com/previous-versions/dotnet/articles/ms973839(v=msdn.10)" rel="noreferrer">Original grand old article by Emmanuel Schanzer</a></li>
<li><a href="https://www.codeproject.com/KB/cs/foreach.aspx" rel="noreferrer">CodeProject FOREACH Vs. FOR</a></li>
<li><a href="https://learn.microsoft.com/archive/blogs/kevin_ransom/to-foreach-or-not-to-foreach-that-is-the-question" rel="noreferrer">Blog - To <code>foreach</code> or not to <code>foreach</code>, that is the question</a></li>
<li><a href="https://web.archive.org/web/20100123104946/http://weblogs.asp.net/mdavey/archive/2004/02/25/79504.aspx" rel="noreferrer">ASP.NET forum - NET 1.1 C# <code>for</code> vs <code>foreach</code></a></li>
</ol>
<p> </p>
<p>[Edit]</p>
<p>Apart from the readability aspect of it, I am really interested in facts and figures. There are applications where the last mile of performance optimization squeezed do matter. </p>

365,650 | <p>When I try to build my project I get the following message in the build window :</p>
<p><strong>========== Build: 0 succeeded or up-to-date, 0 failed, 1 skipped ==========</strong></p>
<p>I tried rebuilding , then building again , but it doesn't help . Is there a way to view more detailed messages ? The "skipped" part doesn't give me any info on what's wrong . I am using Visual Studio 2005 Professional Edition .</p>

365,657 | <p>On my main form, there is another (floatable) window. This floatable window works sort of like a popupwindow in that it will close when the user clicks somewhere else outside of this window. This is handled by the Deactivate event. But what I want to do is, if the user clicks on a different control (say a button), I want to both close this float window and then activate that button with just one click. Currently, the user has to click twice (one to deactivate the window and once more to activate the desired button). Is there a way to do this with just one click?</p>

365,661 | <p>Is it possible for an Subversion client to break a repository in any way? This could be any sort of destructive disruption, but it must be such that it cannot be recovered from without restoring the repository from a backup.</p>
<p>Obviously, deleting everything and then checking that it is easy to fix simply with a rollback, so I am looking for something more than that.</p>

365,669 | <p>I typically use the .markdown or .md extension for markdown documents. Unfortunately spotlight refuses to index them unless they have the .txt file extension.</p>
<p>I've seen a possible solution involving <a href="http://blog.macromates.com/2007/leopard-issues/" rel="noreferrer">editing Info.plist files</a> on the textmate blog. Is there a better way?</p>
<p>Update: I just discovered <a href="http://github.com/mdk/qlmarkdown/" rel="noreferrer">QuickLook generator for Markdown files</a> which adds spotlight support and nice HTML quicklook previews. It works a treat!</p>

365,699 | <p>I find myself doing 2 things quite often in JS, at the moment using jQuery:</p>
<p>The first is the populating of an HTML element, which might look like:</p>
<pre><code>$.get('http://www.example.com/get_result.php', { id: 1 }, function (data) {
$('#elementId').html(data);
});
</code></pre>
<p>The second is populating a select element with a JSON result, such as:</p>
<pre><code>$.getJSON('http://www.example.com/get_result.php', { id: 1 }, function(data) {
$.each(data, function(value, name) {
$('#selectField').append('<option value="' + value + '">' + name + '</option>');
}
)};
</code></pre>
<p>What I'm looking for is either a better what of doing either of these or an extension (either library or a chunk of code) to jQuery that will do these without having to recreate the code all the time. Or is there already something in jQuery that makes this faster?</p>
<p><strong>Edit:</strong> As mentioned by <a href="https://stackoverflow.com/questions/365699/better-way-or-reusable-code-to-populate-an-html-element-or-create-a-select-afte#365790">Kevin Gorski</a>, populating the HTML element could be done as:</p>
<pre><code>$('#elementId').load('http://www.example.com/get_result.php', { id: 1 });
</code></pre>
<p>This is perfect. Although, if you wanted to do a POST, it wouldn't work. Then doing <a href="https://stackoverflow.com/questions/365699/better-way-or-reusable-code-to-populate-an-html-element-or-create-a-select-afte#365797">Collin Allen's</a> method is better.</p>

365,719 | <p>I got a little stuck and I'm hoping someone can point me in the right direction. I have an NSMutableArray that stores a sequence. I created an enumerator so that a while loop can get the content of the array one by one.</p>
<p>Everything works fine however I want the methods to be called with a 10 second gap in between each call. Right now it plays all at once (or in very quick order). What should I look at to create a delay in between method calls?</p>
<p>Below is what I got so far. Thanks!</p>
<pre><code>NSEnumerator * enumerator = [gameSequenceArray objectEnumerator];
id element;
while(element = [enumerator nextObject])
{
NSLog(element);
int elementInt = [element intValue];
[self.view showButton:elementInt];
}

365,743 | <p>I have a small app that has a Render thread. All this thread does is draw my objects at their current location.</p>
<p>I have some code like:</p>
<pre><code>public void render()
{
// ... rendering various objects
if (mouseBall != null) mouseBall.draw()
}
</code></pre>
<p>Then I also have some mouse handler that creates and sets mouseBall to a new ball when the user clicks the mouse. The user can then drag the mouse around and the ball will follow where the mouse goes. When the user releases the ball I have another mouse event that sets mouseBall = null. </p>
<p>The problem is, my render loop is running fast enough that at random times the conditional (mouseBall != null) will return true, but in that split second after that point the user will let go of the mouse and I'll get a nullpointer exception for attempting .draw() on a null object.</p>
<p>What is the solution to a problem like this?</p>

365,750 | <p>I'm using VB.net (2003), and calling the SelectNodes method on an xml document.<br>
If I have a document:</p>
<pre><code><InqRs>
<DetRs>
<RefInfo>
<RefType>StopNum</RefType>
<RefId>0</RefId>
</RefInfo>
<RefInfo>
<RefType>Id</RefType>

<DetRs>

</RefInfo>
<RefInfo>
<RefType>Id</RefType>
<RefId>1</RefId>
</RefInfo>
</DetRs>
</InqRs>
</code></pre>
<p>How can I select just for the <code>DetRs</code> that has <code>RefType=Id</code> and <code>RefId=0</code>, ie, the 'first' one above?</p>
<p>I've tried several different attempts, among others: </p>
<pre><code>InqRs/DetRs[RefInfo/RefType='Id' and RefInfo/RefId='0']
InqRs/DetRs[RefInfo/RefType='Id'][RefInfo/RefId='0']
</code></pre>
<p>But these select both of the DetRs sections (because of the StopNum
RefId of 0, I presume). </p>

365,768 | <p>I have an intel assembly assignment. I need to write a calculator which uses 2 stacks. For example, i have an expression like 23+4/2^4$ .So that $ indicates the end of expression. What I will do is to have two stacks, one for numbers, one for operators and push and pop them according to the operator precedence.</p>
<p>What I need is how can I use 2 stacks for two different purpose at the same time. As long as I know esp register indicates the place for variables in the stack to pop the last or to push a new one. But if I only have one esp register, how can I have two stacks?</p>
<p>Thanks in advance... </p>

365,773 | <p>How do I detect when my Compact Framework application is being smart-minimized (smart minimize is what happens when the user clicks the "X" button in the top-right corner on a Pocket PC)?</p>
<p>The Deactivate event isn't the right way because it occurs in circumstances other than minimization, such as when a message box or another form is shown on top of the main form. And the form's WindowState doesn't help because there is no "Minimized" WindowState on .NET CF.</p>
<p>I heard that by setting MinimizeBox = false, my app will be closed instead of minimized. But I actually don't want my app to close, I just want to know when it has been minimized.</p>

365,780 | <p>As you can see in the image below I have a tree datamodel consisting of groups that can contain other groups plus an arbitary number of items wich again can hold Parameters. The Parameters itself are defined globally and just reoccur in the items. Only the parameter's actual value may differ from parameter usage to parameter usage in the different items.</p>
<p>The image below is an ordinary WPF treeview control with a custom control template and datatemplates for the items.</p>
<p>Now my goal is to remove the parameter names above the textboxes and stack them vertically in a separate column at the very left of the treeview and just leave the textboxes there but also stacked vertically so they the correspond with their parameter names in the first column.</p>
<p>Is there a way I can solve this with control templates and data templates and databinding to the view model ? (Yes I use MVVM)</p>
<p><a href="http://img242.imageshack.us/img242/5377/treebh8.th.png" rel="nofollow noreferrer">treeview image http://img242.imageshack.us/img242/5377/treebh8.th.png</a>
<a href="http://img242.imageshack.us/img242/5377/treebh8.png" rel="nofollow noreferrer">image link</a></p>
<p>The problem is a general layout problem that must work well with databinding. generally I want to bind the object graph to a view that somewhat looks like this (cutout mockup):</p>
<p><a href="http://img75.imageshack.us/img75/5763/treelayoutjh5.jpg" rel="nofollow noreferrer">treelayout http://img75.imageshack.us/img75/5763/treelayoutjh5.jpg</a></p>
<p>Note that the ParamX headers are not really part of the treelayout anymore. But the values still are. Now the values must keep a connection (i.e. the are on the same row) with them. Also if none of the items in the tree contain for example Param1 the Param1 header and the corresponding row must completely dissappear.</p>

365,782 | <p>What is the accepted/most commonly used way to manipulate dynamic (with all dimensions not known until runtime) multi-dimensional arrays in C and/or C++.</p>
<p>I'm trying to find the cleanest way to accomplish what this Java code does:</p>
<pre><code>public static void main(String[] args){
Scanner sc=new Scanner(System.in);
int rows=sc.nextInt();
int cols=sc.nextInt();
int[][] data=new int[rows][cols];
manipulate(data);
}
public static void manipulate(int[][] data){
for(int i=0;i<data.length;i++)
for(int j=0;j<data[0].length.j++){
System.out.print(data[i][j]);
}
}
</code></pre>
<p>(reads from std_in just to clarify that dimensions aren't known until runtime).</p>
<p>Edit:I noticed that this question is pretty popular even though it's pretty old. I don't actually agree with the top voted answer. I think the best choice for C is to use a single-dimensional array as Guge said below "You can alloc rows<em>cols</em>sizeof(int) and access it by table[row*cols+col].".</p>
<p>There is a number of choices with C++, if you really like boost or stl then the answers below might be preferable, but the simplest and probably fastest choice is to use a single dimensional array as in C.</p>
<p>Another viable choice in C and C++ if you want the [][] syntax is lillq's answer down at the bottom is manually building the array with lots of malloc's.</p>

365,823 | <p>Curious to get people's thoughts. I conduct frequent interviews, and have had enough in my career to reflect on them, and I've noticed a broad array of questions. I made this c++ specific, but it's worth noting that I have had people ask me algorithmic complexity questions over the phone, and I don't even mean what is the complexity of a hash lookup vs. a binary tree, I mean more like analytical problems, such as "imagine there are 4 bumble bees, each buzzing bla bla bla."</p>
<p>Now personally I prefer to keep phone screens a little more concrete, and leave the abstract questions for the white board. So when conducting c++ phone interviews, what kind of topics do you cover, especially for Sr. developers?</p>
<p>I know there is another thread similar to this, but frankly it seems to completely have missed the point that this is about phone screens, not interviews that are face to face. Plus this is more c++ specific.</p>

365,841 | <p>My Windows application runs under Wine, but the installation is a bit of a headache for laymen, and the wrappers I've seen online (PlayOnLinux, Wine Doors) require even more packages to be installed. Is there a way to make a package that will install Wine if the user needs it to be installed, install the application and shortcuts, all with minimal user hassle?</p>

365,866 | <p><b>Background</b><br />
I'm researching the efficiency of messaging within contemporary web applications, examining the use of alternatives to XML. This is a university project whose results will be released publicly - the greater the participation of the community, the greater the value of the results that are given back.</p>
<p>I need as many real-life examples of XML in use as possible so as to:</p>
<ul>
<li>fully understand to what uses XML is put when host A talks to host B<br />
I can certainly imagine how XML should/may be used. The reality may be quite different.<br /> </li>
<li>perform tests on actual not hypothetical data<br />How XML performs compared to Technology X on sets of <em>real-life</em> data is of equal importance to how XML compares to Technology X on an <em>arbitrary</em> set of data<br /> </li>
<li>identify and measure any patterns of use of XML<br /> e.g. elements-only, elements plus some attributes or minimal elements and heavy attribute usage</li>
</ul>
<p><b>The Question</b><br /></p>
<p><b>How do <em>you</em> use XML within the world of web applications?</b></p>
<p>When Host B returns XML-structured data to Host A over HTTP, what comes back? This may be a server returning data in an AJAX environment or one server collating data from one or more other servers.</p>
<p>Ideal answers would include:</p>
<ul>
<li>A real-life example of XML within an HTTP response</li>
<li>The URL, where relevant, to request the above</li>
<li>An explanation, if needed, of what the data represents</li>
<li>An explanation, if not obvious, of why such messages are being exchanged (e.g. to fulfil a user request; host X returning a health status report to host Y)</li>
</ul>
<p>I'd prefer examples from applications/services that <i>you've</i> made, developed or worked on, although any examples are welcome. Anything from a 5-line XML document to a 10,000 line monster would be great.</p>
<p>Your own opinions on the use of XML in your example would also be wonderful (e.g. we implemented XML-structured responses because of Requirement X/Person Y even though I thought JSON would have been better because ...; or, we use XML to do this because [really good reason] and it's just the best choice for the job).</p>
<p><strong>Update</strong><br />
I very much appreciate all answers on the topic of XML in general, however what I'm really looking for is <em>real-life examples of HTTP response bodies containing XML</em>.</p>
<p>I'm currently fairly aware of the history of XML, of what common alternatives may exist and how they may compare in features and suitability to given scenarios.</p>
<p>What would be of greater benefit would be a impression of how XML is currently used in the exchange of data between HTTP hosts regardless of whether any current usage is correct or suitable. Examples of cases where XML is misapplied are just as valuable as cases where XML is correctly-applied.</p>
