293,342 | <p>I am using HtmlAgilityPack. I create an HtmlDocument and LoadHtml with the following string:</p>
<pre><code><select id="foo_Bar" name="foo.Bar"><option selected="selected" value="1">One</option><option value="2">Two</option></select>
</code></pre>
<p>This does some unexpected things. First, it gives two parser errors, EndTagNotRequired. Second, the select node has 4 children - two for the option tags and two more for the inner text of the option tags. Last, the OuterHtml is like this:</p>
<pre><code><select id="foo_Bar" name="foo.Bar"><option selected="selected" value="1">One<option value="2">Two</select>
</code></pre>
<p>So basically it is deciding for me to drop the closing tags on the options. Let's leave aside for a moment whether it is proper and desirable to do that. I am using HtmlAgilityPack to test HTML generation code, so I don't want it to make any decision for me or give any errors unless the HTML is truly malformed. Is there some way to make it behave how I want? I tried setting some of the options for HtmlDocument, specifically:</p>
<pre><code> doc.OptionAutoCloseOnEnd = false;
doc.OptionCheckSyntax = false;
doc.OptionFixNestedTags = false;
</code></pre>
<p>This is not working. If HtmlAgilityPack cannot do what I want, can you recommend something that can?</p>

293,344 | <p>I am making a little GUI frontend for a app at the moment using wxPython.</p>
<p>I am using <code>wx.StaticText()</code> to create a place to hold some text, code below:</p>
<pre><code>content = wx.StaticText(panel, -1, "Text Here", style=wx.ALIGN_CENTRE)
</code></pre>
<p>I have a button when clicked retrieves data from MySQL, I am wanting to change the value of the <code>StaticText()</code> to the MySQL data or what else could I use the hold the data.</p>
<p>I have tried using the below method: </p>
<pre><code>contents = wx.TextCtrl(bkg, style=wx.TE_MULTILINE | wx.HSCROLL)
content.SetValue("New Text")
</code></pre>
<p>This displays the data fine but after the data is loaded you can edit the data and I do not want this.</p>
<p>Hope you guys understand what I am trying to do, I am new to Python :)</p>
<p>Cheers</p>

293,351 | <p>I have an owner-drawn UserControl where I've implemented double-buffering. In order to get double-buffering to work without flicker, I have to override the OnPaintBackground event like so:</p>
<pre><code>protected override void OnPaintBackground(PaintEventArgs e)
{
// don't even have to do anything else
}
</code></pre>
<p>This works great at runtime. The problem is that when I have an instance of the control on a form at design time, it becomes a black hole that shows trails of whatever windows are dragged over it (because the override of the OnPaintBackground event also governs design-time appearance). It's just a cosmetic problem, but it's visually jarring and it always leads new developers on the project to assume something has gone horribly wrong.</p>
<p>Is there any way to have an overridden method like this not be overridden at design time, or is there another solution?</p>

293,353 | <p>Method chaining is the only way I know to build fluent interfaces.</p>
<p>Here's an example in C#:</p>
<pre><code>John john = new JohnBuilder()
.AddSmartCode("c#")
.WithfluentInterface("Please")
.ButHow("Dunno");
Assert.IsNotNull(john);
[Test]
public void Should_Assign_Due_Date_With_7DayTermsVia_Invoice_Builder()
{
DateTime now = DateTime.Now;
IInvoice invoice = new InvoiceBuilder()
.IssuedOn(now)
.WithInvoiceNumber(40)
.WithPaymentTerms(PaymentTerms.SevenDays)
.Generate();
Assert.IsTrue(invoice.DateDue == now.AddDays(7));
}
</code></pre>
<p>So how do others create fluent interfaces. How do you create it? What language/platform/technology is needed?</p>

293,375 | <p>On a site where 90% of the pages use the same libraries, should you just load the libraries all the time or only load them when needed? The other pages would be ajax or simple pages that don't have any real functionality.</p>
<p>Also, should you only load the code when needed? If part way down a page you need a library, should you load it then or just load it at the top. Maybe it's possible it may never get there before of an error or wrong data. (Loading at the top makes it somewhat easier to understand, but may result in extra code not needed.)</p>
<p>I'm also wondering if I should make the libraries more specific so I'm not say loading the code to edit at the same time as viewing?</p>
<p>Basically, how much should I worry about loading code or not loading code?</p>

293,380 | <p>I'm just starting out writing trying to write a simple program in C and I am using Visual Studios to do so. I heard that it does compile C as well as C++. And I know that it does because it says it compiles. The only problem is that when I go to the output directory, there isn't a .exe file in the directory! It has the following:</p>
<ul>
<li>BuildLog.html</li>
<li>mt.dep</li>
<li>test1.obj</li>
<li>vc90.idb</li>
<li>vc90.pdb</li>
</ul>
<p>But that is all! No EXE. I've looked through all the options and made sure that it is set to compile to an exe and i checked the output file. That is $(OutDir)\$(ProjectName).exe. But alas, no exe appears. Any ideas?</p>
<p>Also when i try to hit f5 and run with debut i get an error that says</p>
<blockquote>
<p>This application has failed to start
because MSVCR90.DLL was not found.
Re-installing the application may fix
this problem</p>

293,388 | <p>I am working on a J2ME project that spawns worker threads for numerous tasks such as downloading HTTP content. The basic thread layout is similar to most java apps--there is a main UI thread and worker threads spawned to do stuff behind the scenes. My question is what is the best way to handle exceptions that occur in the worker threads? </p>
<p>I usually adhere to the design rationale that most exceptions should be percolate as far as possible. When I write single threaded apps, it is common for me to percolate the exceptions all the way up to the UI layer and then report them in an error dialog to the user. Is there a similar practice for multithreaded apps? The most intuitive thing to me is to catch exceptions in the Thread.run() and then call an invokeLater on the UI thread to report it in a dialog. The issue I see here is that outside of the worker thread dying off prematurely, this approach does not really notify the UI thread there was an error. I do not see a clear way to throw an exception across threads so to speak.</p>
<p>Thanks,
Andy</p>

293,389 | <p>PHP provides a mechanism to register a shutdown function:</p>
<pre><code>register_shutdown_function('shutdown_func');
</code></pre>
<p>The problem is that in the recent versions of PHP, this function is still executed DURING the request. </p>
<p>I have a platform (in Zend Framework if that matters) where any piece of code throughout the request can register an entry to be logged into the database. Rather than have tons of individual insert statements throughout the request, slowing the page down, I queue them up to be insert at the end of the request. I would like to be able to do this after the HTTP request is complete with the user so the length of time to log or do any other cleanup tasks doesn't affect the user's perceived load time of the page.</p>
<p>Is there a built in method in PHP to do this? Or do I need to configure some kind of shared memory space scheme with an external process and signal that process to do the logging?</p>

293,409 | <p>I'm still new to ROR, so pardon the simplicity of the question...</p>
<p>So <a href="http://www.example.com/controller/:id" rel="nofollow noreferrer">http://www.example.com/controller/:id</a> displays a record in my table, with :id being a number (1,2,3 etc.).</p>
<p>Is there a way I can have :id in the URL be the value of a field in the displayed record? Such that I can have <a href="http://www.example.com/controller/record_field" rel="nofollow noreferrer">http://www.example.com/controller/record_field</a>? I want to have a human-friendly reference to specific records in my table. I'm sure this must be possible. Do I change something in routes.rb?</p>
<p>Thanks for the help!</p>

293,421 | <p>I have a vector-like class that contains an array of objects of type <code>"T"</code>, and I want to implement 4 arithmetic operators, which will apply the operation on each item:</p>
<pre><code>// Constructors and other functions are omitted for brevity.
template<class T, unsigned int D>
class Vector {
public:
// Add a value to each item: naive implementation.
void operator += (const T&) {
for (int i = 0; i < D; ++i) {
data[i] += value;
}
}
void operator -= (const T&) { ... }
void operator *= (const T&) { ... }
void operator /= (const T&) { ... }
private:
T items[D];
};
</code></pre>
<p>Because operators will contain the same boilerplate code (looping over every element and applying appropriate operation), I thought I could generalize it:</p>
<pre><code>template<class T, unsigned int D>
class Vector {
public:
void operator += (const T& value) { do_for_each(???, value); }
void operator -= (const T& value) { do_for_each(???, value); }
void operator *= (const T& value) { do_for_each(???, value); }
void operator /= (const T& value) { do_for_each(???, value); }
private:
void
do_for_each(std::binary_function<void, T, T>& op, T value) {
std::for_each(data, data + D, std::bind2nd(op, value));
}
T data[D];
};
</code></pre>
<p>Now, the problem is, how do I pass an operator that takes two intrinsic types and returns <code>void</code> to <code>do_for_each</code>, as depicted in the example above? C++ does not let me do this trick for intrinsic types (<code>"T::operator+="</code> will not work if <code>"T"</code> is <code>"int"</code>).</p>

293,423 | <p>I've been utilizing <code>NHibernate 2.0.1.4000</code> on all current .NET 3.5 SP1 projects and have had no problems with any other queries (utilizing either the Query or Criteria APIs), until some new business logic dictated the necessity of a new query in this particular project against the application's database that needs to retrieve records with a specific null property (of type DateTime) from a single table.</p>
<p>Knowing that you cannot use the not-equal restriction for this type of query, but instead can use the IsNull restriction, this simple query generates a "Value cannot be null!" Exception when executed. I have extensive DEBUG mode log4net log files, which I have reviewed and haven't yet helped, and I have verified that my class for the table does specify the property I'm checking for is a nullable property (DateTime?) to avoid the problems that can cause by forcing updates to the record, etc., which isn't happening here...</p>
<p>Here's the query, nothing complex, and I've tried with/without the MaxResults additional restriction to eliminate it as a problem, and yet, everytime, the exception gets thrown before I can collect the results:</p>
<pre><code>ICriteria criteria = session.GetISession().CreateCriteria(typeof (Order)).Add(NHibernate.Criterion.Restrictions.IsNull("ShippedOn")).SetMaxResults(10);
IList<Order> entityList = criteria.List<Order>();
</code></pre>
<p>Any ideas or pointers to more information that might help me solve this? I've tried using HQL alternatively, same problems... Am I missing something here with regards to returning records with a specific null property?</p>

293,438 | <p>How can I pad a string with spaces on the left when using printf?</p>
<p>For example, I want to print "Hello" with 40 spaces preceding it.</p>
<p>Also, the string I want to print consists of multiple lines. Do I need to print each line separately?</p>
<p>EDIT: Just to be clear, I want exactly 40 spaces printed before every line.</p>

293,444 | <p>I'm writing a simple program that's going to parse a logfile of a packet dump from wireshark into a more readable form. I'm doing this with python.</p>
<p>Currently I'm stuck on this part:</p>
<pre><code>for i in range(len(linelist)):
if '### SERVER' in linelist[i]:
#do server parsing stuff
packet = linelist[i:find("\n\n", i, len(linelist))]
</code></pre>
<p>linelist is a list created using the readlines() method, so every line in the file is an element in the list. I'm iterating through it for all occurances of "### SERVER", then grabbing all lines after it until the next empty line(which signifies the end of the packet). I must be doing something wrong, because not only is find() not working, but I have a feeling there's a better way to grab everything between ### SERVER and the next occurance of a blank line.</p>
<p>Any ideas?</p>

293,482 | <p>I need to sanitize HTML submitted by the user by closing any open tags with correct nesting order. I have been looking for an algorithm or Python code to do this but haven't found anything except some half-baked implementations in PHP, etc.</p>
<p>For example, something like</p>
<pre><code><p>
<ul>
<li>Foo
</code></pre>
<p>becomes</p>
<pre><code><p>
<ul>
<li>Foo</li>
</ul>

293,495 | <p>I have a dropdown box and a literal tag inside an Update Panel. On the selection change event of the dropdown up requery the database and repopulate the literal tag and then call UPdatePanel.Update().</p>
<p>below, is there are way i can avoid having to create a new Oledbconnection each time as this seems slow. Can i reuse and store:</p>
<ol>
<li>The Datasource</li>
<li>The connection in the page. </li>
</ol>
<p>if so, how do i keep this state between calls from the GUI to the server? Here is my selection change code below</p>

293,499 | <p>Yesterday, I found myself writing code like this:</p>
<pre><code>SomeStruct getSomeStruct()
{
SomeStruct input;
cin >> input.x;
cin >> input.y;
}
</code></pre>
<p>Of course forgetting to actually return the struct I just created. Oddly enough, the values in the struct that <em>was</em> returned by this function got initialized to zero (when compiled using g++ that is). Is this just a coincidence or did another SomeStruct get created and initialized somewhere implicitly?</p>

293,500 | <p>We have built a custom socket server in ruby and packaged it as a gem. Since this is an internal project we can not simply publish it to RubyForge or GitHub. I tried to setup our own gem server but gem would not authenticate over https. Our other deployment is all for standard rails applications that use capistrano and svn for deployment.</p>
<p>Our current setup which is to use a rails-like deployment with capistrano. which does the following:</p>
<ul>
<li>Check out the code from svn</li>
<li>Build the gem</li>
<li>Install the gem</li>
<li>Restart the server</li>
</ul>
<p>This just seems awkward, and makes the gem packaging seem like extra work -- but outside of the deployment issue it fits really nicely as a gem.</p>
<p>Is there a cleaner approach?</p>

293,602 | <p>I have a ASP.NET project and when building the project it is showing build suceessfull. But when I am building the deployment project, it is showing build failed with an error message </p>
<pre><code>Error 5 "aspnet_compiler.exe" exited with code 1
</code></pre>
<p>I rechecked my project and found that when i am removing the line <strong><code><!--#include file="admin/topstyle.asp"--></code></strong>, it is working fine. If I use this line, I am getting error building web deployment project to create my dll.</p>
<p><strong>topstyle.asp</strong> is a file which render some common styles for the page like heading image and all.</p>
<p>Can anyone tell me how to get rid of this problem?</p>

293,617 | <p>I'm writing a file that requires dates to be in decimal format:</p>
<blockquote>
<p><code>2007-04-24T13:18:09</code> becomes <code>39196.554270833331000</code> </p>
</blockquote>
<p>Does anyone have a time formatter that will do this (Decimal time is what VB/Office, etc. use)?</p>
<p>Basic code goes like follows:</p>
<pre><code>final DateTime date = new DateTime(2007, 04, 24, 13, 18, 9, 0, DateTimeZone.UTC);
double decimalTime = (double) date.plusYears(70).plusDays(1).getMillis() / (Days.ONE.toStandardDuration().getMillis())); //=39196.554270833331000.
</code></pre>
<p>For the example above.</p>
<p>(I started on a DateTimePrinter that would do this, but it's too hard for now (I don't have the joda source linked, so I can't get ideas easily)).</p>
<p>Note: Decimal time is the number of days since 1900 - the . represents partial days. 2.6666666 would be 4pm on January 2, 1900</p>

293,649 | <p>I'd like to rank my stories based on "controversy" quotient. For example, reddit.com currently has "controversial" section: <a href="http://www.reddit.com/controversial/" rel="nofollow noreferrer">http://www.reddit.com/controversial/</a></p>
<p>When a story has a lot of up and a lot of down votes, it's controversial even though the total score is 0 (for example). How should I calculate this quotient score so that when there's a lot of people voting up and down, I can capture this somehow.</p>
<p>Thanks!!!</p>

293,668 | <p>is it possible to use the ajaxComplete or ajaxStop features of jQuery to decide whether or not the callback gets called?</p>

293,672 | <p>A few weeks back I was using std::ifstream to read in some files and it was failing immediately on open because the file was larger than 4GB. At the time I couldnt find a decent answer as to why it was limited to 32 bit files sizes, so I wrote my own using native OS API.</p>
<p>So, my question then: Is there a way to handle files greater than 4GB in size using std::ifstream/std::ostream (IE: standard c++)</p>
<p>EDIT: Using the STL implementation from the VC 9 compiler (Visual Studio 2008).
EDIT2: Surely there has to be standard way to support file sizes larger than 4GB.</p>

293,694 | <p>i've got regex which was alright, but as it camed out doesn't work well in some situations </p>
<p><strong>Keep eye on message preview cause message editor do some tricky things with "\"</strong></p>
<blockquote>
<p>[\[]?[\^%#\$\*@\-;].*?[\^%#\$\*@\-;][\]]</p>
</blockquote>
<p>its task is to find pattern which in general looks like that</p>
<blockquote>
<p>[ABA]</p>
</blockquote>
<ul>
<li>A - char from set ^,%,#,$,*,@,-,;</li>
<li>B - some text</li>
<li>[ and ] are included in pattern</li>
</ul>
<p>is expected to find all occurences of this pattern in test string</p>
<blockquote>
<p>Black fox [#sample1#] [%sample2%] - [#sample3#] eats blocks.</p>
</blockquote>
<p>but instead of expected list of matches</p>
<ul>
<li>"[#sample1#]" </li>
<li>"[%sample2%]"</li>
<li>"[#sample3#]" </li>
</ul>
<p>I get this</p>
<ul>
<li>"[#sample1#]" </li>
<li>"[%sample2%]"</li>
<li>"- [#sample3#]" </li>
</ul>
<p>And it seems that this problem will occur also with other chars in set "A". So could somebody suggest changes to my regex to make it work as i need?</p>
<p>and less important thing, how to make my regex to exclude patterns which look like that</p>
<blockquote>
<p>[ABC]</p>
</blockquote>
<ul>
<li>A - char from set ^,%,#,$,*,@,-,;</li>
<li>B - some text</li>
<li>C - char from set ^,%,#,$,*,@,-,; <strong>other than A</strong></li>
<li>[ and ] are included in pattern</li>
</ul>
<p>for example</p>
<blockquote>
<p>[$sample1#] [%sample2@] [%sample3;]</p>
</blockquote>
<p>thanks in advance</p>

<p>Like some of the commenters mentioned, the script only ends up returning results based on the last word in the search terms. So I have also tried to implement one of the suggestions from another user, but now I seem to only be able to get results based on the first search term.</p>
<p>The code for my script can be found here: <a href="http://php.pastebin.com/m7759afd3" rel="nofollow noreferrer">http://php.pastebin.com/m7759afd3</a></p>
<p>My print_r for the results looks like this:</p>
<pre><code>SELECT * FROM blog WHERE blog_title LIKE '%barry%' OR blog_content LIKE '%barry%' AND blog_title LIKE '%child%' OR blog_content LIKE '%child%' AND blog_title LIKE '%help%' OR blog_content LIKE '%help%' ORDER BY blog_title
SELECT * FROM links WHERE link_title LIKE '%barry%' OR link_desc LIKE '%barry%' AND link_title LIKE '%child%' OR link_desc LIKE '%child%' AND link_title LIKE '%help%' OR link_desc LIKE '%help%' ORDER BY link_title
SELECT * FROM pages WHERE page_title LIKE '%barry%' OR page_content LIKE '%barry%' AND page_title LIKE '%child%' OR page_content LIKE '%child%' AND page_title LIKE '%help%' OR page_content LIKE '%help%' ORDER BY page_title

293,761 | <p>How can I make Emacs show blank spaces (like a space, a tab, a line-jump, etc). Many other editors like Kate and Eclipse have this feature and I find it very useful to see when code is indent-broken because of mix of spaces and tabs (particularly Python).</p>

293,780 | <p>Is there a way to get the amount of free diskspace of a disk or a folder in a CMD
without having to install some thirdparty applications?</p>
<p>I have a CMD that copies a big file to a given directory and could of course use
the errorlevel return from the copy command, but then I have to wait for the time
it takes to copy the file (eg...to that then the disk is full and the copy operation fails).</p>
<p>I would like to know before I start the copy if it is any idea at all. Tried the DU.EXE utility from Sysinternals, but that show occupied space only.</p>

293,790 | <p>I am trying to wire up dependency injection with Windsor to standard asp.net web forms. I think I have achieved this using a HttpModule and a CustomAttribute (code shown below), although the solution seems a little clunky and was wondering if there is a better supported solution out of the box with Windsor?</p>
<p>There are several files all shown together here</p>
<pre><code> // index.aspx.cs
public partial class IndexPage : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Logger.Write("page loading");
}
[Inject]
public ILogger Logger { get; set; }
}
// WindsorHttpModule.cs
public class WindsorHttpModule : IHttpModule
{
private HttpApplication _application;
private IoCProvider _iocProvider;
public void Init(HttpApplication context)
{
_application = context;
_iocProvider = context as IoCProvider;
if(_iocProvider == null)
{
throw new InvalidOperationException("Application must implement IoCProvider");
}
_application.PreRequestHandlerExecute += InitiateWindsor;
}
private void InitiateWindsor(object sender, System.EventArgs e)
{
Page currentPage = _application.Context.CurrentHandler as Page;
if(currentPage != null)
{
InjectPropertiesOn(currentPage);
currentPage.InitComplete += delegate { InjectUserControls(currentPage); };
}
}
private void InjectUserControls(Control parent)
{
if(parent.Controls != null)
{
foreach (Control control in parent.Controls)
{
if(control is UserControl)
{
InjectPropertiesOn(control);
}
InjectUserControls(control);
}
}
}
private void InjectPropertiesOn(object currentPage)
{
PropertyInfo[] properties = currentPage.GetType().GetProperties();
foreach(PropertyInfo property in properties)
{
object[] attributes = property.GetCustomAttributes(typeof (InjectAttribute), false);
if(attributes != null && attributes.Length > 0)
{
object valueToInject = _iocProvider.Container.Resolve(property.PropertyType);
property.SetValue(currentPage, valueToInject, null);
}
}
}
}
// Global.asax.cs
public class Global : System.Web.HttpApplication, IoCProvider
{
private IWindsorContainer _container;
public override void Init()
{
base.Init();
InitializeIoC();
}
private void InitializeIoC()

293,794 | <p>Greetings,</p>
<p>I have data stored on mysql with delimiter "," in 1 table.
I have rows and column stored on database too.
Now i have to output the data using rows and column number stored on database to draw the table.</p>
<p>Rows and column number are user input, so it may varies.</p>
<p>Let say, there is number 3 on column and 3 on rows.</p>
<p>I need to do it like display like,</p>
<pre><code>|___d1__|___d2__|___d3__|
|___d4__|___d5__|___d6__|
|___d7__|___d8__|___d9__|
</code></pre>
<p>Where d1-d9 would be the data stored on mysql database with delimiter "," in one table.</p>
<p>Thanks for helping me.</p>

293,799 | <p>The <em>VS2008 SP1</em> documentation talks about <strong><code>std::tr1::mem_fun</code></strong>.</p>
<p>So why, when I try and use <strong><code>std::tr1::mem_fun</code></strong>, why do I get this compile error?:</p>
<pre><code>'mem_fun' : is not a member of 'std::tr1'
</code></pre>
<p>At the same time, I can use <strong><code>std::tr1::function</code></strong> without problems.</p>
<p>Here is the sample code I am trying to compile, which is supposed to call <code>TakesInt</code> on an instance of <code>Test</code>, via a <code>function<void (int)></code>:</p>
<pre><code>#include "stdafx.h"
#include <iostream>
#include <functional>
#include <memory>
struct Test { void TakesInt(int i) { std::cout << i; } };
void _tmain()
{
Test* t = new Test();
//error C2039: 'mem_fun' : is not a member of 'std::tr1'
std::tr1::function<void (int)> f =
std::tr1::bind(std::tr1::mem_fun(&Test::TakesInt), t);
f(2);
}
</code></pre>
<p>I'm trying to use the tr1 version of <strong><code>mem_fun</code></strong>, because when using <strong><code>std::mem_fun</code></strong> my code doesn't compile either! I can't tell from the compiler error whether the problem is with my code or whether it would be fixed by using tr1's <strong><code>mem_fun</code></strong>. That's C++ compiler errors for you (or maybe it's just me!).</p>
<p><HR/></p>
<h2>Update: Right. The answer is to spell it correctly as mem_fn!</h2>
<p>However when I fix that, the code still doesn't compile. </p>
<p>Here's the compiler error:</p>
<pre><code>error C2562:
'std::tr1::_Callable_obj<_Ty,_Indirect>::_ApplyX' :
'void' function returning a value
</code></pre>

293,806 | <p>What I would like to do is have VS2008, when I open a code file, collapse all members of the classes/interfaces in the file by default (including, crucially, any XML documentation and comments).</p>
<p>I do <em>not</em> want to use regions, at all.</p>
<p>I would also like to be able to use the ctrl+m, ctrl+l chord to toggle all <em>member</em> outlining (for example, if everything is collapsed, I would like it to expand all of the members, but not the comments or XML documentation).</p>
<p>Possible? How?</p>

293,814 | <p>Helo!</p>
<p>Is this possible to use string value of one node which tells what type of field is presented in another node using LINQ to XML?</p>
<p>For example:</p>
<pre><code><node>
<name>nodeName</name>
<type>string</type>
</node>
<node>
<name>0</name>
<type>bool</type>
</node>
<node>
<name>42</name>
<type>int</type>
</node>
</code></pre>
<p>Thanks in advance</p>

293,831 | <p>For example, I make extensive use of the session in my ASP.NET application but have heard somewhere that objects stored in session can be removed by the system where server memory runs low. Is this true? Is there any session 'callback' functionality to allow you to re-populate scavenged objects? </p>
<p>More generally, what other potential problems of using session state are there, and what are the suggested best practices for dealing with them?</p>

293,832 | <p>I am currently building an application using ASP.NET MVC. The data entry pages are fairly easy to code, I just make the Model for the page of the type of my business object:</p>
<pre><code>namespace MyNameSpace.Web.Views.ProjectEdit
{
public partial class MyView : ViewPage<Project>
{
}
}
</code></pre>
<p>Where I am struggling is figuring out the best way to implement a dashboard like interface, with stand-alone parts, using ASP.NET MVC, where the Model for each part would be different? I'm <strong>assuming</strong> that each part would be an MVC user control. </p>
<p>Also, how could I make it so each part is testable?</p>

293,840 | <p>This is probably a simple question. Suppose I have a object called Users and it contains a lot of protected variables. </p>
<p>Inside that Users class I have a method that creates a temporary Users object, does something with it, and if successful, transfers all the variables from the temp Users object into the one I have. </p>
<p>Is there some fast way to transfer all the variables from one Users object into another Users object without doing this using C#?</p>

this.LastName = temp.LastName;

293,853 | <p>I would like to add custom tooltips to emacs.
More specifically, whenever I hover on a symbol (function/variable) name
with my mouse of I would like to see a tooltip with the symbol's definition.
I know that I can find this kind of info with a tool like cscope but I have no idea how
to attach the output of cscope to a tooltip.
does anyone have a partial (how to link a callback to a tooltip in emacs in general) or
a full (how do I actually link the output of cscope to a tooltip) solution to this?</p>
<p>Thanks,
Nir</p>

<p>I am wondering how to make <code>AudioFileGetProperty</code> work.</p>
<p>My sound file is <a href="http://chineseresume.com/localbiz/uploads/myfilename_7_Recording.caf" rel="nofollow noreferrer">here</a>,
you could right-click and download from <a href="http://chineseresume.com/test.html" rel="nofollow noreferrer">here</a>.</p>
<p>I am using this way to set the URL in the <code>-[AudioViewController playOrStop]</code> method:</p>
<pre><code>// AudioPlayer *thePlayer = [[AudioPlayer alloc] initWithURL: self.soundFileURL];
AudioPlayer *thePlayer = [[AudioPlayer alloc] initWithURL:
[NSURL URLWithString: @"http://chineseresume.com/localbiz/uploads/myfilename_7_Recording.caf"]];
</code></pre>
<p>Any suggestion is highly welcome.</p>

<p>I want to query a list of companies that can access a particular system as well as the number of users who can access the system inside the company. </p>
<p>This query works for all cases except for one very important one. If a company can access a the system but none of the users can, the Company disappears completely from the query (i.e.: Users.CanAccessSystem = false). In that case, I just want the UserCount = 0. </p>
<p>Example From Companies that Can Access the System:</p>
<pre><code>Users Company Name
1 WidgetWorks
3 WidgetCompany
0 WidgesRUs
</code></pre>
<p>This system is on MySQL</p>
<p>Query Edit: Fixed a Typo "ON User.CompanyId = Company.Id"</p>

293,956 | <p>I've been working with jQuery for a pair of weeks and I've noticed it works fine with objects that are in the original HTML document, but when I generate a new element using jQuery the library doesn't get any of its events.</p>
<p>Let's say I try to run something like this:</p>
<pre><code>$('.whatever').click(function() {
alert("ALERT!");
});
</code></pre>
<p>If the HTML does have something like this:</p>
<pre><code><span class="whatever">Whatever</span>
</code></pre>
<p>Then clicking on the word <code>Whatever</code> gets me a nice alert.</p>
<p>But if the <code>span</code> element is added dynamically using jQuery, nothing happens when clicking on it.</p>
<p>Is there a way to make jQuery work with those elements, somehow?</p>

293,972 | <p>There's a HTML:</p>
<pre><code><div class="test">
<ul>
<li>Item 1</li>
<li>Item 2</li>
</ul>

<p>And a bit of JS:</p>
<pre><code>$(document).ready(function() {
// do stuff when DOM is ready
$(".test ul").append('<li>Foo</li>');
});
</code></pre>
<p>Why does it add nothing, but if I remove html from append's argument string,</p>
<pre><code>.append('Foo')
</code></pre>
<p>it works - but that's not the point - new text is added as anonymous block, not li item as I wanted.</p>
<p>Anu suggestions?</p>
<p><em>edit:</em>
Argh, I've found the problem. I modified a file saved from Firefox's "Save page" option, the extension was .xhtml - and here's the problem. I renamed it and it works fine.</p>
<p>Thanks :)</p>

293,988 | <p>Is there a good way in C++ to implement (or fake) a type for a generic vector of vectors?</p>
<p>Ignore the issue of when a vector of vectors is a good idea (unless there's something equivalent which is always better). Assume that it does accurately model the problem, and that a matrix does not accurately model the problem. Assume also that templated functions taking these things as parameters do need to manipulate the structure (e.g. calling push_back), so they can't just take a generic type supporting <code>[][]</code>.</p>
<p>What I want to do is:</p>
<pre><code>template<typename T>
typedef vector< vector<T> > vecvec;
vecvec<int> intSequences;
vecvec<string> stringSequences;
</code></pre>
<p>but of course that's not possible, since typedef can't be templated.</p>
<pre><code>#define vecvec(T) vector< vector<T> >
</code></pre>
<p>is close, and would save duplicating the type across every templated function which operates on vecvecs, but would not be popular with most C++ programmers.</p>

294,009 | <p>When comparing two objects (of the same type), it makes sense to have a compare function which takes another instance of the same class. If I implement this as a virtual function in the base class, then the signature of the function has to reference the base class in derived classes also. What is the elegant way to tackle this? Should the Compare not be virtual?</p>
<pre><code>class A
{
A();
~A();
virtual int Compare(A Other);
}
class B: A
{
B();
~B();
int Compare(A Other);
}
class C: A
{
C();
~C();
int Compare(A Other);
}
</code></pre>

294,018 | <p>What are some C++ related idioms, misconceptions, and gotchas that you've learnt from experience?</p>
<p>An example:</p>
<pre><code>class A
{
public:
char s[1024];
char *p;
A::A()
{
p = s;
}
void changeS() const
{
p[0] = 'a';
}
};
</code></pre>
<p>Even know changeS is a const member function, it is changing the value of the object. So a const member function only means that it will treat all variables as const, and it does not mean that it will actually keep all members const. (why? the const keyword on the member function treats char *p; as char * const p; And not as const char *p;</p>
<p>Which therefore means that p can't point to something else. And not that you can't change p's data. </p>

294,040 | <p>Maybe this is an easy question, maybe not. I have a select box where I hardcode with width. Say 120px.</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-html lang-html prettyprint-override"><code><select style="width: 120px">

<p>I want to be able to show the second option so that the user can see the full length of the text.</p>
<p>Like everything else. This works fine in Firefox, but doesn't work with Internet Explorer6.</p>

294,077 | <p>I have a large amount of rows in the database from which I need to create an XML document. I am using hibernate 3. The basic list() method in Criteria and Query interfaces looks dangerous: I quess it pretty much has to read all the records into memory even if I only iterate over them. Or is there some lazy loading magic? If not, I seem to have two options left: using scroll() or iterate() from Query (scroll is also present in Criteria). iterate doesn't look all that great either if I want to have minimal SQL roundtrips: "The first SQL query returns identifiers only". So am I right, do I have to use scroll() for this?</p>

294,092 | <p>I've just written a small XBox 360 Wireless Controller managed interface that basically
wraps around the low-lever <a href="http://slimdx.mdxinfo.com/wiki/index.php?title=Main_Page" rel="nofollow noreferrer">SlimDX</a> wrapper library and provides a easy, managed API for the XBOX 360 controller.</p>
<p>Internally, the class polls the gamepad every N ms, and shoots events as it detects changes in the underlying state of the controller.</p>
<p>I'm experiencing some what dead end with timers that is basiclly forcing to choose between the lesser of two evils:</p>
<ul>
<li><p>Either make my XBox360GamePad class UI framework specific (i.e. support WPF/WinForms will be hard-coded in the class, and the class has to reference these frameworks...)</p></li>
<li><p>Make the class completely framework agnostic, but force the users to sprinkle their code with Dispatcher.Invoke / Invoke() calls to be able to update UI according to the events generated.</p></li>
</ul>
<p>If I choose the latter option (of making the code UI agnostic), then I basically use the "generic" System.Timers.Timer or any timer that has no UI dependency.
In that case I end up having events generated/called from a thread that is incapable of directly updating the UI, i.e. in WPF, I would have to issue every update originated form the 360 controller class through the (ugly) use of Dispatcher.Invoke.</p>
<p>On the other hand, If I use DispatcherTimer inside the XBox 360 Controller class I have a working component that can update the UI directly with no fuss, but now my whole controller class is coupled to WPF, and it can't be used without being dependent on WPF (i.e. in a pure console app)</p>
<p>What I'm kind of looking is a some sort solution that would allow me to be both framework agnostic and also update UI without having to resort to all kinds of Dispatcher.Invoke() techniques...
If for example there was a shared base class for all timers, I could somehow inject the timer as a dependency according to the relevant scenario..
Has anyone ever dealt successfully with this sort of problem?</p>

294,138 | <p>What's the best way to merge 2 or more dictionaries (<code>Dictionary<T1,T2></code>) in C#?
(3.0 features like LINQ are fine).</p>
<p>I'm thinking of a method signature along the lines of:</p>
<pre><code>public static Dictionary<TKey,TValue>
Merge<TKey,TValue>(Dictionary<TKey,TValue>[] dictionaries);
</code></pre>
<p>or</p>
<pre><code>public static Dictionary<TKey,TValue>
Merge<TKey,TValue>(IEnumerable<Dictionary<TKey,TValue>> dictionaries);
</code></pre>
<p><strong>EDIT:</strong> Got a cool solution from JaredPar and Jon Skeet, but I was thinking of something that handles duplicate keys. In case of collision, it doesn't matter which value is saved to the dict as long as it's consistent.</p>

294,193 | <p>I normally use scp to copy stuff, but now I'm trying to get used to the more powerful rsync command. It helps me use less bandwidth by copying up only files that have changed. However, rsync has a lot of complex parameters, so I thought, hey, I'll just make a little Bash script that makes it easy for me, and call the command 'rscp'. So, off I went building something like this. Note in the example below that my web host uses a different port number besides 22, so that's why the $1 is used for that.</p>
<pre><code>#!/bin/bash
rsync -avzp --progress --rsh='ssh -p$1' $2 $3 $4 $5 $6 $7
</code></pre>
<p>So, its usage, I hoped, would be something like:</p>
<pre><code>rscp 3822 --exclude=tiny_mce /var/www/mysite/* root@webhost.com:~/www/mysite
</code></pre>
<p>That would make it a little bit closer to my usage of the scp command, you see.</p>
<p>However, when I ran this, I get this error:</p>
<pre><code>building file list ...
4 files to consider
ERROR: destination must be a directory when copying more than 1 file
rsync error: errors selecting input/output files, dirs (code 3) at main.c(494) [receiver=2.6.9]
rsync: connection unexpectedly closed (8 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(454) [sender=2.6.9]
</code></pre>
<p>But if I go back to the regular rsync command, it works just fine.</p>
<p>Can anyone figure out what I'm doing wrong in my Bash script?</p>

294,217 | <p>In ARM assembly immediates are encoded by an 8-bit rotated value which means we can only encode </p>
<pre><code>(0-256)^2n.
</code></pre>
<p>Now my problem is that I want to clear the upper 16-bits of r0 and replace it with the half-word stored r1. But because of the limited range of the immediates I have to do: -</p>
<pre><code>bic r0, r0, #0xff000000
bic r0, r0, #0x00ff0000
add r0, r0, r1, LSL #16
</code></pre>
<p>Is it possible to do replace the 2 bic instructions with a single instruction? 0xffff0000 is unencodable. Perhaps I should be using another logical operation to clear the upper 16-bits?</p>
<p>Thanks</p>
<p>EDIT: Sorry I forgot to say that the top 16-bits of r1 is empty, and I'm using an ARM7TDMI</p>

294,234 | <p>I'm working on an assignment that is telling me to assume that I have a singly linked list with a header and tail nodes. It wants me to insert an item y before position p. Can anybody please look over my code and tell me if I'm on the right track? If not, can you provide me with any tips or pointers (no pun intended)? </p>
<pre><code>tmp = new Node();
tmp.element = p.element;
tmp.next = p.next;
p.element = y;
p.next = tmp;
</code></pre>
<p>I think I may be wrong because I do not utilize the header and tail nodes at all even though they are specifically mentioned in the description of the problem. I was thinking of writing a while loop to traverse the list until it found p and tackle the problem that way but that wouldn't be constant-time, would it?</p>

<p>That said, if I want to invoke the <em>callable</em> member on the object with the default argument, what's the correct syntax?</p>
<pre><code>std::tr1::mem_fn(&Class::member)(object); // This does not work
</code></pre>
<p>g++ complains with the following error:</p>
<pre><code>test.cc:17: error: no match for call to ‘(std::tr1::_Mem_fn<void (Class::*)(int)>) (Class&)’
/usr/include/c++/4.3/tr1_impl/functional:551: note: candidates are: _Res std::tr1::_Mem_fn<_Res (_Class::*)(_ArgTypes ...)>::operator()(_Class&, _ArgTypes ...) const [with _Res = void, _Class = Class, _ArgTypes = int]
/usr/include/c++/4.3/tr1_impl/functional:556: note: _Res std::tr1::_Mem_fn<_Res (_Class::*)(_ArgTypes ...)>::operator()(_Class*, _ArgTypes ...) const [with _Res = void, _Class = Class, _ArgTypes = int]
</code></pre>
<p>Still, the I have the same problem when Class::member is overloaded by members that takes different arguments...</p>

294,270 | <p>How would you call the constructor of the following class in these three situations: Global objects, arrays of objects, and objects contained in another class/struct?</p>
<p>The class with the constructor (used in all three examples):</p>
<pre><code>class Foo {
public:
Foo(int a) { b = a; }
private:
int b;
};
</code></pre>
<p>And here are my attempts at calling this constructor:</p>
<h2>Global objects</h2>
<pre><code>Foo global_foo(3); // works, but I can't control when the constructor is called.
int main() {
// ...
}
</code></pre>
<h2>Arrays of objects</h2>
<pre><code>int main() {
// Array on stack
Foo array_of_foos[30](3); // doesn't work
// Array on heap
Foo *pointer_to_another_array = new Foo(3) [30]; // doesn't work
}
</code></pre>
<p>There I'm attempting to call the constructor for all elements of the arrays, but I'd also like to know how to call it on individual elements.</p>
<h2>Objects contained in classes/structs</h2>
<pre><code>class Bar {
Foo foo(3); // doesn't work
};
int main() {
Bar bar;
}
</code></pre>

294,285 | <p>I want to automate several tasks (eg. simulate eclipse style <kbd>ctrl</kbd>-<kbd>shift</kbd>-<kbd>R</kbd> open dialog for other editors). The general pattern is: the user will press some key combination, my program will detect it and potentially pop up a dialog to get user input, and then run a corresponding command, typically by running an executable.</p>
<p>My target environment is windows, although cross-platform would be nice. My program would be started once, read a configuration file, and sit in the background till triggered by a key combination or other event.</p>
<p>Basically autohotkey.</p>
<p>Why not just use autohotkey? I actually have quite a few autohotkey macros, but I'd prefer to use a saner language.</p>
<p>My question is: is there a good way to have a background python process detect key combinations?</p>
<p>Update: found the answer using pyHook and the win32 extensions:</p>
<pre><code>import pyHook
import pythoncom
def OnKeyboardEvent(event):
print event.Ascii
hm = pyHook.HookManager()
hm.KeyDown = OnKeyboardEvent
hm.HookKeyboard()
while True:
pythoncom.PumpMessages()

294,297 | <p>I'm writing a Web application that needs to store JSON data in a small, fixed-size server-side cache via AJAX (think: <a href="http://code.google.com/apis/opensocial/articles/persistence-0.8.html#restrictions-quotas" rel="noreferrer">Opensocial quotas</a>). I do not have control over the server.</p>
<p>I need to reduce the size of the stored data to stay within a server-side quota, and was hoping to be able to gzip the stringified JSON in the browser before sending it up to the server.</p>
<p>However, I cannot find much in the way of JavaScript implementations of Gzip. Any suggestions for how I can compress the data on the client side before sending it up?</p>

294,299 | <p>I created an Ajax website in Visual Studio, added a simple page with a textbox and button, when I click the button once everything works, when I click it twice I get the error</p>

294,313 | <p>Python provides the "*" operator for unpacking a list of tuples and giving them to a function as arguments, like so:</p>
<pre><code>args = [3, 6]
range(*args) # call with arguments unpacked from a list
</code></pre>
<p>This is equivalent to:</p>
<pre><code>range(3, 6)
</code></pre>
<p>Does anyone know if there is a way to achieve this in PHP? Some googling for variations of "PHP Unpack" hasn't immediately turned up anything.. perhaps it's called something different in PHP?</p>

294,343 | <p>I am looking for a simple C++ library for tokenizing and parsing RTF (Rich Text Format) files. I am planning to edit them with Qt's QTextEdit.</p>
<p>More the Formatting preserved the better -- but actually I am planning to use Bold and Italics only.</p>
<p>In perl I would use <a href="http://search.cpan.org/%7Esargie/RTF-Tokenizer-1.10/lib/RTF/Tokenizer.pm" rel="nofollow noreferrer">RTF::Tokenizer</a>.</p>
<p>It would be nice if the module had some sort of interface for writing also, but I am able to brute force that with a template and some regular expressions.</p>

294,349 | <p>I am trying to create a sidebar for a site that will allow a user to select an item from a drop down menu and show an RSS Feed. The feed will change depending on which item is selected from the list. I am not sure how to acomplish this, but my first thought was to use z-index and show/hide layers. I have one layer and the menu set up, but it will not allow me to change the feed displayed when a different menu item is selected. Does anyone know how I can acomplish this?</p>
<p>I have a live preview up of what I have gotten done so far. It's located on the site, <a href="http://www.chud.com/articles/templates/chud/new_sidebarhome.php" rel="nofollow noreferrer">CHUD</a>,</p>
