<pre><code>string [] files = new string[2];
files[0] = "ThinkFarAhead.Example.Settings.Configuration_Local.xml";
files[1] = "ThinkFarAhead.Example.Settings.Configuration_Global.xml";
//Resharper complains this is an "access to modified closure"
for (int i = 0; i < files.Length; i++ )
{
// Resharper disable AccessToModifiedClosure
if(Array.Exists(Assembly.GetExecutingAssembly().GetManifestResourceNames(),
delegate(string name) { return name.Equals(files[i]); }))
return Assembly.GetExecutingAssembly().GetManifestResourceStream(files[i]);
// ReSharper restore AccessToModifiedClosure
}
</code></pre>
<p>The above seems to work fine though ReSharper complains that this is "access to modified closure". Can any one shed light on this?</p>

<p>I was wondering about implementing my own sessions (more for an exercise than anything else) for a GAE app I'm working ... at first I was thinking of using the datastore to store the session data. However, every time something needs to be added to the session 'bucket', it would require saving to the datastore. Obviously that's bad since we want to minimize our writes. Then I thought about using memcache ... seemed like a good idea but then we're faced with issues of possible session corruption due to memcache being "evicted through memory pressure" by Google. So does that mean we are left with only the following options:</p>
<ol>
<li>Storing all session data in cookies</li>
<li>Writing all session data to datastore and memcache, and then only reading from memcache</li>
</ol>
<p>Anyone have any other ideas?</p>

<p>Can anyone suggest some references or other resources that are useful in learning MCML?</p>
<p>I have a small pet project I have been working on for a while using C# and .Net 3.5. I have reached a point where I want to be able to send output from it to Windows Media Center, but I have been having a hard time finding coherent explanations of how to create MCML elements to represent my C# data objects. Particularly I am having a hard time finding information on creating an MCML element for each element in a C# collection. Any suggestions?</p>

<p>What is the best way to validate a crontab entry with PHP? Should I be using a regex, or an external library? I've got a PHP script that adds/removes entries from a crontab file, but want to have some way to verify that the time interval portion is in a valid format.</p>

<p>Way back when I was working in an Oracle shop I took the CONNECT_BY for granted. Now I'm stuck working with SQL Server 2005 and have some nasty object hierarchies. Specifically, we have a self referencing table where all child records have a column with their parent's id. Currently we have a view that maps children to levels in the hierarchy and a nasty query that does the heavy lifting to connect parents with their children. While this method works, it is far from elegant and reeks of taint. I'm just curious how other people retrieve hierarchical data from SQL Server 2005.</p>

<p>Using jQuery, how would you <code>show()</code> every <code>div.foo</code> on a page in a random order, with a new one appearing every X milliseconds?</p>
<p><strong>Clarification</strong>: I want to start with all these elements hidden and end with all of them showing, so it wouldn't make sense to <code>show()</code> the same element twice.</p>
<p>I originally thought I'd make an array listing all the elements, randomly pick one, show that one, remove it from the array using <code>splice()</code>, and then randomly pick the next one from the remaining list - etc. But since my array is part of a jQuery object, <code>splice()</code> is not available.</p>

<p>When a user clicks a link to download a file on my website, they go to <a href="http://viewsourcecode.org/viewsource/homebrew.php" rel="noreferrer">this PHP file</a> which increments a download counter for that file and then header()-redirects them to the actual file. I suspect that bots are following the download link, however, so the number of downloads is inaccurate.</p>
<ul>
<li>How do I let bots know that they shouldn't follow the link?</li>
<li>Is there a way to detect most bots?</li>
<li>Is there a better way to count the number of downloads a file gets?</li>

<p>The MessageQueueException has no public constructor, only the standard protected constructor for an exception. Is there an appropriate way to throw this exception from the mock object / Expect.Call statement?</p>

<p>I have the following situation:</p>
<p>A user will define a certain filter on a page, and on postback I will query the database using that filter and return a bunch of matching records to the user, each with a checkbox next to it, so he can choose whether to act on each of those records.</p>
<p>In Classic ASP / PHP I can generate a lot of controls named "chk__*" and then on postback go through all the $<em>POST entries looking for the ones prefixed "chk</em>".</p>
<p>What is the best way to do this in ASP.Net 2.0?</p>
<p>I can do it easily by implementing a Repeater with a Template containing the checkbox, bind the Repeater to a Dataset, and then on the second Postback, I just do:</p>
<pre><code>For Each it As RepeaterItem In repContacts.Items
Dim chkTemp As CheckBox = DirectCast(it.FindControl("cbSelect"), CheckBox)
If chkTemp.Checked Then
End If
Next
</code></pre>
<p>However this has the <em>slight</em> disadvantage of giving me a HUGE Viewstate, which is really bad because the client will need to re-upload the whole viewstate to the server, and these people will probably be using my site over a crappy connection.</p>
<p>Any other ideas?
(I can also create the controls dynamically and iterate through Request.Form as in the old days, however, I was looking for a cleaner </p>

<p>Suppose a header file defines a function template. Now suppose two implementation files <code>#include</code> this header, and each of them has a call to the function template. In both implementation files the function template is instantiated with the same type.</p>
<pre><code>// header.hh
template <typename T>
void f(const T& o)
{
// ...
}
// impl1.cc
#include "header.hh"
void fimpl1()
{
f(42);
}
// impl2.cc
#include "header.hh"
void fimpl2()
{
f(24);
}
</code></pre>
<p>One may expect the linker would complain about multiple definitions of <code>f()</code>. Specifically, if <code>f()</code> wouldn't be a template then that would indeed be the case.</p>
<ul>
<li>How come the linker doesn't complain about multiple definitions of <code>f()</code>?</li>
<li>Is it specified in the standard that the linker must handle this situation gracefully? In other words, can I always count on programs similar to the above to compile and link?</li>
<li>If the linker can be clever enough to disambiguate a set of function template instantiations, why can't it do the same for regular functions, given they are identical as is the case for instantiated function templates?</li>
</ul>

<p>I received an error when an referenced .NET Framework 2.0 assembly tried to execute the following line of code in an IIS hosted WCF service:</p>
<p>Error Message:</p>
<blockquote>
<p>exePath must be specified when not
running inside a stand alone exe.</p>
</blockquote>
<p>Source Code:</p>
<pre><code>ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
</code></pre>
<p>Has anyone experienced this issue and do they know how to resolve it?</p>
<p><b>EDIT:</b> My question is, what is the best way to open a configuration file (app.config and web.config) from a WCF service that is backwards compatible with a .NET 2.0 assembly?</p>

<p>There are many different styles of variable names that I've come across over the years.</p>
<p>The current wikipedia entry on naming conventions is fairly light... </p>
<p>I'd love to see a concise catalog of variable naming-conventions, identifying it by a name/description, and some examples. </p>
<p>If a convention is particularly favored by a certain platform community, that would be worth noting, too.</p>
<p>I'm turning this into a community wiki, so please create an answer for each convention, and edit as needed.</p>

<p>I have the following string expression in a PowerShell script:</p>
<pre><code>"select count(*) cnt from ${schema}.${table} where ${col.column_name} is null"
</code></pre>
<p>The schema and table resolve to the values of $schema and $table, respectively. However, an empty string is supplied for ${col.column_name}. How can I dot into the member of a variable as part of a string substitution?</p>

<p>After looking at another question on SO (<a href="https://stackoverflow.com/questions/235386/using-nan-in-c">Using NaN in C++</a>) I became curious about <code>std::numeric_limits<double>::signaling_NaN()</code>.</p>
<p>I could not get signaling_NaN to throw an exception. I thought perhaps by signaling it really meant a signal so I tried catching SIGFPE but nope...</p>
<p>Here is my code:</p>
<pre><code>double my_nan = numeric_limits<double>::signaling_NaN();
my_nan++;
my_nan += 5;
my_nan = my_nan / 10;
my_nan = 15 / my_nan;
cout << my_nan << endl;
</code></pre>
<p><code>numeric_limits<double>::has_signaling_NaN</code> evaluates to true, so it is implemented on my system.</p>
<p>Any ideas?</p>
<p>I am using ms visual studio .net 2003's C++ compiler. I want to test it on another when I get home.</p>
<p>Thanks!</p>

<p>In the filesystem I have</p>
<pre>
/file.aspx
/directory/default.aspx
</pre>
<p>I want to configure IIS so that it returns the appropriate file (add the aspx extension) or directory (default content page) as follows:</p>
<pre>
/file -> /file.aspx
/directory -> /directory/default.aspx
/directory/ -> /directory/default.aspx
</pre>
<p>I have configured the Wildcard application mapping set to C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll. When the "Verify that file exists" is unchecked, the the file request works but not the directory request (returns 404). When the "Verify that file exists" is checked, the directory request works but not the file request.</p>
<p>How can I configure it so that both the file and directory requests will work?</p>

<p>I have a script that slides a div down from behind the menu, when people click on the tab. However its in jquery and I want to use mootools (lots of reasons I wont go into here). However im stuck with mootools 1.1 at present. But for some reason my attempt is not working :(</p>
<p>The html</p>
<pre><code>print("code sample");
<div id="panel">
<form action="">
< form here >
</form>
</div>
<div class="slide">
<p class="sl"><a href="#" class="btn-slide" id="toggle"><span></span></a></p>
</code></pre>
<p>Div id panel holds the form which slides down, div class slide and the P tag is replaced by a tab/button which hangs down via css, clicking on this slides the tab down.</p>
<p>The jquery (which works fine)</p>
<pre><code>print("code sample");
<script type="text/javascript">
$j(document).ready(function(){
$j(".btn-slide").click(function(){
$j("#panel").slideToggle("slow");
$j(this).toggleClass("active"); return false;
});
});
</script>
</code></pre>
<p>My moo attempt</p>
<pre><code>print("code sample");
<script type="text/javascript">
window.addEvent('domready', function(){
var mySlide = new Fx.Slide('panel');
$('toggle').addEvent('click', function(e){
e = new Event(e);
mySlide.toggle();
e.stop();
});
});
</script>
</code></pre>
<p>Like I said above I am restricted to moo 1.1 at present, but if there is a answer that will work with both 1.1 and 1.2 or if its a similar change I would be grateful to hear, as it will be updated at some point.</p>

<p>I <em>think</em> I know how to create custom encrypted RSA keys, but how can I read one encrypted like ssh-keygen does?</p>
<p>I know I can do this:</p>
<pre><code>OpenSSL::PKey::RSA.new(File.read('private_key'))
</code></pre>
<p>But then OpenSSL asks me for the passphrase... How can I pass it to OpenSSL as a parameter?</p>
<p>And, how can I create one compatible to the ones generated by ssh-keygen?</p>
<p>I do something like this to create private encrypted keys:</p>
<pre><code>pass = '123456'
key = OpenSSL::PKey::RSA.new(1024)
key = "0000000000000000#{key.to_der}"
c = OpenSSL::Cipher::Cipher.new('aes-256-cbc')
c.encrypt
c.key = Digest::SHA1.hexdigest(pass).unpack('a2' * 32).map {|x| x.hex}.pack('c' * 32)
c.iv = iv
encrypted_key = c.update(key)
encrypted_key << c.final
</code></pre>
<p>Also, keys generated by OpenSSL::PKey::RSA.new(1024) (without encryption), don't work when I try password-less logins (i.e., I copy the public key to the server and use the private one to login).</p>
<p>Also, when I open an ssh-keygen file via OpenSSL and then check its contents, it appears to have additional characters at the beginning and end of the key. Is this normal?</p>
<p>I don't really understand some of this security stuff, but I'm trying to learn. What is it that I'm doing wrong?</p>

<p>How can my vbscript detect whether or not it is running in a UAC elevated context?</p>
<p>I have no problem detecting the user, and seeing if the user is within the Administrators group. But this still doesn't answer the question of whether the process has elevated privs or not, when running under Vista or Windows 2008. Please note, I need only to <em>detect</em> this status; not attempt to elevate or (err ..) de-elevate.</p>

<p>Does anyone know if it is possible to convert a HTML page (url) to a PDF using iText?</p>
<p>If the answer is 'no' than that is OK as well since I will stop wasting my time trying to work it out and just spend some money on one of a number of components which I know can :)</p>

<p>I'm trying to get a background image of a HTML element (body, div, etc.) to stretch its entire width and height.</p>
<p>Not having much luck. Is it even possible or do I have to do it some other way besides it being a background image?</p>
<p>My current css is:</p>
<pre><code>body {
background-position: left top;
background-image: url(_images/home.jpg);
background-repeat: no-repeat;
}
</code></pre>
<p>Thanks in advance.</p>
<p>Edit: I'm not keen on maintaining the CSS in Gabriel's suggestion so I'm changing the layout of the page instead. But that seems like the best answer so I'm marking it as such.</p>

<p>Given this algorithm, I would like to know if there exists an iterative version. Also, I want to know if the iterative version can be faster.</p>
<p>This some kind of pseudo-python...</p>
<p>the algorithm returns a reference to root of the tree</p>
<pre><code>make_tree(array a)
if len(a) == 0
return None;
node = pick a random point from the array
calculate distances of the point against the others
calculate median of such distances
node.left = make_tree(subset of the array, such that the distance of points is lower to the median of distances)
node.right = make_tree(subset, such the distance is greater or equal to the median)
return node
</code></pre>

<p>I get the following message in a VC6 project compile:</p>
<blockquote>
<p>OTE: WINVER has been defined as 0x0500 or greater which enables
Windows NT 5.0 and Windows 98 features. When these headers were released,
Windows NT 5.0 beta 1 and Windows 98 beta 2.1 were the current versions.
For this release when WINVER is defined as 0x0500 or greater, you can only
build beta or test applications. To build a retail application,
set WINVER to 0x0400 or visit <a href="http://www.microsoft.com/msdn/sdk" rel="nofollow noreferrer">http://www.microsoft.com/msdn/sdk</a>
to see if retail Windows NT 5.0 or Windows 98 headers are available.
See the SDK release notes for more information.</p>
</blockquote>
<p>Any idea what is going on?</p>
<p>It builds and links fine. </p>
<p>I have VC6, VS2005 and 2008 on my XP machine. </p>
<p>Perhaps my Platform SDK is not up to date?</p>

<p>How can I convert an <code>Int64</code> to an <code>Int32</code> type in F# without using the <code>Microsoft.FSharp.Compatibility.Int32.of_int64</code>?</p>
<p>I'm doing this because interactive doesn't seem to work when I try:</p>
<pre><code>open Microsoft.FSharp.Compatibility
</code></pre>
<p>With <code>FSharp.PowerPack</code> added as a reference it says: </p>
<blockquote>
<p>error FS0039: The namespace 'Compatibility' is not defined.</p>
</blockquote>
<p><strong>Edit:</strong> Does anyone have an answer to the question? The suggestions about the int types are useful and informative, but I'm having the same issue opening the powerpack namespace in F# interactive.</p>

<p>I created a simple .NET windows application in Visual Studio 2005 and on just entering the main form load event my threads window is as in the following image:</p>
<p><a href="http://img519.imageshack.us/my.php?image=threadshh4.jpg" rel="nofollow noreferrer">http://img519.imageshack.us/my.php?image=threadshh4.jpg</a></p>
<p>My questions are</p>
<p>1)Why are there so many threads in the first place when I haven't started any(apart from my application's 'Main Thread')</p>
<p>2)What does this thread named '.Net SystemEvents' do?</p>
<p>3)Why are the entries under the column 'Location' for all threads except the Main Thread empty?</p>
<p><strong>EDIT:</strong><br>
4) Is it possible to make these thread not start? or go away after some time?<br>
5) What are they meant to do? what is their purpose?</p>

<p>Making a small app, and I want a function to execute 50% of the time. So if I were to dbl click the exe half the time the function would execute, and the other half it wouldn't. I can't seem to find anyway to easily do this, the one solution I tried seemed to determine the chance on compile rather than on run. Thanks in advance!</p>

<p>I am writing an application where I will be accessing the database from django and from a stand alone application. Both need to do session verification and the session should be the same for both of them. Django has a built in authentication/session verification, which is what I am using, now I need to figure out how to reuse the same session for my stand alone application.</p>
<p>My question is how can I look up a session_key for a particular user?</p>
<p>From what it looks there is nothing that ties together auth_user and django_session</p>

<p>I have a (derived) Menu control, that displays a rather large list of items from a custom data source. I need to disable ViewState on the menu to avoid the very annoying "Can't select a disabled or unselectable menu item" when some other control causes the current selection to change on a postback.</p>
<p>Unfortunately, when ViewState is disabled for the Menu, the postbacks generated <em>by</em> the menu aren't raising any events. If I enable ViewState, the OnMenuItemClick event is raised. If I disable ViewState, OnMenuItemClick is not raised. I'm perplexed.</p>
<p>I need to leave ViewState off for the menu, so how can I handle postbacks from the actual menu?</p>
<p>At this point I'm leaning towards using the Menu's Load event, parsing the __EVENTTARGET to see if it's the Menu, and going from there. This would technically process the postback event before it would normally but that's ok, I guess.</p>
<p>Any better ideas?</p>

<p>I am working on a web page that is using jQuery. I have an Ajax call that gets data from the server and updates a div. Inside that data there is a jQuery function, but the function is not being called after the data is loaded into the page. I have the proper js files included in the page already.</p>
<p>This is what is returned from the Ajax call and placed into a div:</p>
<pre><code><script type="text/javascript">
$(function() {
$('input').myFunction('param');
});
</script>
<p> other html </p>
</code></pre>
<p>How do I get the returned javascript to run after the html is inserted into the page?</p>
<p>(I am using Rails with the jRails plugin )</p>

<p>I have a windows application running at the backend. I have functions in this applications mapped to hot keys. Like if I put a message box into this function and give hot key as <kbd>Alt</kbd>+<kbd>Ctrl</kbd>+<kbd>D</kbd>. then on pressing <kbd>Alt</kbd>, <kbd>Ctrl</kbd> and <kbd>D</kbd> together the message box comes up. My application is working fine till this point. </p>
<p>Now I want to write a code inside this function so that when I am using another application like notepad, I select a particular line of text and press the hot key <kbd>Alt</kbd> + <kbd>Ctrl</kbd> + <kbd>D</kbd> it is supposed to copy the selected text append it with "_copied" and paste it back to notepad. </p>
<p>Anyone who has tried a similar application please help me with your valuable inputs.</p>

<p>The most favorite feature of StackOverflow for me is that it can automatically detect code in post and set appropriate color to the code.</p>
<p>I'm wondering how the color is set. When I do a <kbd>Ctrl</kbd>+<kbd>F5</kbd> on a page, the code seems first be black text, then change to be colorful. Is it done by jQuery?</p>

<p>My understanding is that in unix, when memory is freed, the memory doesn't get returned back to the operating system, it stays in the process to be used again for the next call to malloc.</p>
<p>On windows, I understand that the memory actually gets returned to the operating system.</p>
<p>Is there any big difference between these two ways of doing things or are they just two different ways of doing the same thing? And if there are any pros/cons to these two methods, what are they?</p>
<p><strong>EDIT:</strong> Thanks for the clarification. I had always thought this was an OS thing (since processes never seem to decrease in size in UNIX-like systems, but do in windows).</p>

<p>I've been reading many a tutorial/article on unmanaged DLLs in C++. For the life of me, however, I cannot seem to grasp the concept. I'm easily confused by the seeming disagreement about whether it needs a header file, how to export it, whether I need a .lib file and what have you.</p>
<p>So, let's assume I have just a function like so:</p>
<pre><code>public int calculateSquare(int num)
{
return num*num;
}
</code></pre>
<p>Ignoring the actual code, what do I require to make this simple function, by itself, into a DLL which I can then call? Do I just add __dllexport or whatever it is to the first line or do I require a header? I am perplexed by all of this.</p>

<p>I am facing this peculiar problem. My webapp, works fine on my localhost. Its a JSP/Struts-Tomcat-MySQL app. However, when I host it on hostjava.net (shared tomcat), it is unable to connect to the database.</p>
<p>After some debugging, I have identified the problem, to be with JNDI lookup for datasource. If you want, you can take a look at the log at <a href="http://rohitesh.hostjava.net/MapsDummyLog.htm" rel="nofollow noreferrer">http://rohitesh.hostjava.net/MapsDummyLog.htm</a></p>
<p>Some details on the context information location :
/META-INF/context.xml contains :</p>
<pre><code><Context path="" docBase="" debug="5" reloadable="true" crossContext="true" override="true">
<Resource name="jdbc/ConnectionPooling" auth="Container" type="javax.sql.DataSource"
maxActive="10" maxIdle="5" username="[username]" password="[password]" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost/[db name]?autoReconnect=true" />
</Context>
</code></pre>
<p>Can anyone help me find out, where am going wrong, please?</p>
<p>Cheers,

<p>Why do some sites (or advertisers that give clients javascript code) employ a technique of splitting the <code><script></code> and/or <code></script></code> tags up within <code>document.write()</code> calls?</p>
<p>I noticed that Amazon does this as well, for example:</p>
<pre><code><script type='text/javascript'>
if (typeof window['jQuery'] == 'undefined') document.write('<scr'+'ipt type="text/javascript" src="http://z-ecx.images-amazon.com/images/G/01/javascripts/lib/jquery/jquery-1.2.6.pack._V265113567_.js"></sc'+'ript>');
</script>
</code></pre>

<p>I've recently been trying to create units tests for some legacy code.</p>
<p>I've been taking the approach of using the linker to show me which functions cause link errors, greping the source to find the definition and creating a stub from that. </p>
<p>Is there an easier way?
Is there some kind of C++ parser that can give me class definitions, in some easy to use form, from which I can generate stubs?</p>

<p>In XEmacs this is done by the calling the function char-to-ucs on a character. GNU Emacs does not seem to have this function. In GNU Emacs, characters seem to be ordinary integers. Running C-x = on a latin character reveals that the Emacs codepoint is different from the Unicode codepoint for the corresponding character. How do I find the Unicode codepoint of the character at point in GNU Emacs?</p>

<p>Suppose I have this Windows wchar_t string:</p>
<pre><code>L"\x4f60\x597d"
</code></pre>
<p>and</p>
<pre><code>L"\x00e4\x00a0\x597d"
</code></pre>
<p>and would like to convert it (not necessarily programmatically; it will be a one-time thing) to GCC/Linux wchar_t format, which is UTF-32 AFAIK. How do I do it? (a general explanation would be nice, but example based on this concrete case would be helpful as well)</p>
<p><em>Please don't direct me to character conversion sites. I would like to convert from L"\x(something)" form and not "end character" form.</em></p>

<p>How do I iterate over the words of a string composed of words separated by whitespace?</p>
<p>Note that I'm not interested in C string functions or that kind of character manipulation/access. I prefer elegance over efficiency. My current solution:</p>
<pre><code>#include <iostream>
#include <sstream>
#include <string>
using namespace std;
int main() {
string s = "Somewhere down the road";
istringstream iss(s);
do {
string subs;
iss >> subs;
cout << "Substring: " << subs << endl;
} while (iss);
}
</code></pre>

<p>I recently started using Git as my version control system for some Cocoa projects I'm working on and wondered if there are best practices for working with version control systems on Cocoa projects.</p>
<p>There is the obvious "build" directory which I exclude from versioning as it's not important and can change quite a bit when debugging some code and then there are those .pbxuser and .perspectivev3 which change ever time I open the project in Xcode but I don't really know if they are "important" enough to be checked in.</p>
<p>Is there a commonly used configuration for excluding unimportant files?</p>
<p>Thanks in advance</p>

<p>I am using System.IO.Directory.GetCurrentDirectory() to get the current directory in my web service, but that does not give me the current directory. How do I get the current directory in a web service?</p>

<p>I have several <code>std::vector</code>, all of the same length. I want to sort one of these vectors, and apply the same transformation to all of the other vectors. Is there a neat way of doing this? (preferably using the STL or Boost)? Some of the vectors hold <code>int</code>s and some of them <code>std::string</code>s.</p>
<p>Pseudo code:</p>
<pre><code>std::vector<int> Index = { 3, 1, 2 };
std::vector<std::string> Values = { "Third", "First", "Second" };
Transformation = sort(Index);
Index is now { 1, 2, 3};
... magic happens as Transformation is applied to Values ...
Values are now { "First", "Second", "Third" };
</code></pre>

<p>I have a div with a <code><h1></code> tag in a div, with no margins. If I define any doctype, a white space appears above the div.</p>
<p>If I remove the <code><h1></code> tags, or remove the doctype definition, there is no space (as there should be. Why?</p>
<p>Example HTML:</p>
<pre><code><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<style>
body {
margin:0
}
#thediv {
background-color:green
}
</style>
</head>
<body>
<div id="thediv">
<h1>test</h1>
</div>
</body>
</html>
</code></pre>
<p>The problem is the space above the green div, remove the DOCTYPE and the space disappears, change the <code><h1></code> tag to <code><b></code> and the space also disappears. It happens with any doctype (XHTML/HTML, strict/transitional/etc)</p>
<p>Happens in almost all browsers (Using <a href="http://browsershots.org" rel="nofollow noreferrer">http://browsershots.org</a>). Amusingly, the only browser that seems to display it correctly was Internet Explorer 6.0..</p>

<p>Is it good practice to let abstract classes define instance variables?</p>
<pre><code>public abstract class ExternalScript extends Script {
String source;
public abstract void setSource(String file);
public abstract String getSource();
}
</code></pre>
<p>The sub class, ExternalJavaScript.class, would then automatically get the source variable but I feel it's easier to read the code if all the sub classes themselves define the source, instead of from inheritance. </p>
<p>What is your advice?</p>
<p>/Adam</p>

<p>How should I choose an IPv4 multicast address for my application's use? I may need more than one (a whole range perhaps ultimately) but just want to avoid conflicts with other applications.</p>
<ul>
<li>Packets will be entirely contained within an administrative domain, probably a LAN</li>
<li>If several independent instances of my application are in use on the same network, they could each use their own multicast address - but if they don't, they will be able to coexist anyway, they'll just have a small amount of overhead ignoring each others' packets.</li>
<li>My packets already contain a "magic number" to avoid problems</li>
<li>I will be checking the originator address (which I know can be spoofed of course), TTL and other things to try to prevent unexpected packets mucking things up.</li>
</ul>
<p>Ideas please :)</p>
<p>Currently I've just allocated an arbitrary one from the "local use" space, 239.255.42.99</p>

<p><em>(This question specifically in C#, but applies generally to .NET)</em> </p>
<p>I have a largish application that has a fairly good design, and is broken into major sections over interfaces (this was done to assist parallel development).</p>
<p>We now have a primary set of concrete classes that implement the required interfaces, but we also have additional sets of concrete classes for alternative situations and testing.</p>
<p>At the moment we pull all these classes together at the top level in code:</p>
<pre><code>IMyInterface xComponent = new ConcreteXComponent1();
</code></pre>
<p>If I want to swap out components then I only have to change that line and recompile:</p>
<pre><code>// IMyInterface xComponent = new ConcreteXComponent1();
IMyInterface xComponent = new ConcreteXComponentAlternative();
</code></pre>
<p>That works great, but obviously requires a recompile -- I'd rather the concrete class was chosen using a value from a config file. </p>
<p>What's the standard pattern for changing concrete classes using a configuration file? Is there standard library I can use that solves this problem for me?</p>
<p>Thanks!</p>

<p>I have an <em>SQLite</em> table that contains prices for various products. It's a snapshot table, so it contains the prices on 5 minute intervals. I would like to write a query that would return the difference in price from one row to the next on each item.</p>
<p>The columns are id (auto inc), record_id (id of the product), price (price at that point in time), time (just seconds since epoch)</p>
<p>I'm trying to return a 'difference' column that contains a value of difference between intervals.</p>
<pre>
Given the following
id record_id price time
1 apple001 36.00 ...
67 apple001 37.87 ...
765 apple001 45.82 ...
892 apple001 26.76 ...
I'd like it to return
id record_id price time difference
1 apple001 36.00 ... 0
67 apple001 37.87 ... 1.87
765 apple001 45.82 ... 7.95
892 apple001 26.76 ... -19.06
</pre>
<p>Is it possible with SQLite?</p>
<p>Secondly, should it be possible - is there a way to limit it to the last 5 or so records?</p>
<p>I'd appreciate any help, thanks.</p>
<hr>
<p>Just wanted to add a few things. I've found ways to do so in other databases, but I'm using XULRunner, thus SQLite. Which is why I'm working with it instead. </p>
<p>The secondary question may need clarifying, I'm looking to order by the time and take and analyze the last 5 records. It's an issue I can tackle separately if need be.</p>
<p>Here's a MySQL <a href="http://www.freeopenbook.com/mysqlcookbook/mysqlckbk-CHP-12-SECT-13.html" rel="noreferrer">solution</a>, kind of. It's the approach I'm heading towards, but the deal breaker is "If the table contains a sequence column but there are gaps, renumber it. If the table contains no such column, add one". By design this scenario has gaps as there is many records updated at once and won't be in order.</p>

<p>I am using the following function to load a PlayList of Songs from 'PlayListJSON.aspx' but somethings seems wrong,evrytime OnFailure is getting called, I am unable to debug it further. any help would be really gr8.</p>
<pre><code>Player.prototype.loadPlaylist = function(playlistId, play) {
req = new Ajax.Request('/PlaylistJSON.aspx?id=' + playlistId, {
method: 'GET',
onSuccess: function(transport, json) {
eval(transport.responseText);
player.setPlaylist(playlist.tracklist, playlist.title, playlistId);
player.firstTrack();
if (play) player.playSong();
},
onFailure: function() {
//error
}
});
}

<p>For example, say one was to include a 'delete' keyword in C# 4. Would it be possible to guarantee that you'd never have wild pointers, but still be able to rely on the garbage collecter, due to the reference-based system?</p>
<p>The only way I could see it possibly happening is if instead of references to memory locations, a reference would be an index to a table of pointers to actual objects. However, I'm sure that there'd be some condition where that would break, and it'd be possible to break type safety/have dangling pointers.</p>
<p>EDIT: I'm not talking about just .net. I was just using C# as an example.</p>

<p>I need to compare the integer part of two doubles for inequality and I'm currently doing this:</p>
<pre><code>int iA = (int)dA;
int iB = (int)dB;
if( iA != iB )
{
...
}
</code></pre>
<p>but I wonder if there's a better approach than this.</p>
<p>Thanks.</p>
<p>If I used Math.Truncate() instead of a cast to int, would it still be accurate to compare the two resulting double values for equality?</p>
<p>About the hungarian notation comments:</p>
<p>I never use HN myself, not at least in the way most of people do. But this is one of these rare cases where the semantic of a variable directly relates to its type. I could have chosen another syntax like A_As_Integer and B_As_NonInteger but what would have been the difference then?</p>

<p>So, simple procedure, calculate a factorial number. Code is as follows.</p>
<pre><code>int calcFactorial(int num)
{
int total = 1;
if (num == 0)
{
return 0;
}
for (num; num > 0; num--)
{
total *= num;
}
return total;
}
</code></pre>
<p>Now, this works fine and dandy (There are certainly quicker and more elegant solutions, but this works for me) for most numbers. However when inputting larger numbers such as 250 it, to put it bluntly, craps out. Now, the first couple factorial "bits" for 250 are { 250, 62250, 15126750, 15438000, 3813186000 } for reference.</p>
<p>My code spits out { 250, 62250, 15126750, 15438000, <strong>-481781296</strong> } which is obviously off. My first suspicion was perhaps that I had breached the limit of a 32 bit integer, but given that 2^32 is 4294967296 I don't think so. The only thing I can think of is perhaps that it breaches a <strong>signed</strong> 32-bit limit, but shouldn't it be able to think about this sort of thing? If being signed is the problem I can solve this by making the integer unsigned but this would only be a temporary solution, as the next iteration yields 938043756000 which is far above the 4294967296 limit.</p>
<p>So, is my problem the signed limit? If so, what can I do to calculate large numbers (Though I've a "LargeInteger" class I made a while ago that may be suited!) without coming across this problem again?</p>

<p>What's the best way to handle a visitor constructing their own URL and replacing what we expect to be an ID with anything they like?</p>
<p>For example:</p>
<p><a href="https://stackoverflow.com/questions/236349">ASP.Net MVC - handling bad URL parameters</a></p>
<p>But the user could just as easily replace the URL with:</p>
<p><a href="https://stackoverflow.com/questions/foo">https://stackoverflow.com/questions/foo</a></p>
<p>I've thought of making every Controller Function parameter a <code>String</code>, and using <code>Integer.TryParse()</code> on them - if that passes then I have an ID and can continue, otherwise I can redirect the user to an Unknown / not-found or index View.</p>
<p>Stack Overflow handles it nicely, and I'd like to too - how do you do it, or what would you suggest?</p>

<p>I am a beginner in c++ and I have a small problem:</p>
<p>my code displays a simple menu to the user providing three options:</p>
<pre><code>cout << "\nQuadratic equation: a*X^2 + b*X + c = 0 main menu: ";
cout << "\n <r> Give new coefficients";
cout << "\n <c> Calculate equations solutions";
cout << "\n <t> Terminate the program";
</code></pre>
<p>What I want is now is that, when a user enters:</p>
<ul>
<li>aer ->invalid input entered, try again </li>
<li>1 or any other number->invalid input entered, try again </li>
<li>rt ->invalid input entered,try again
(here the first character is correct but he entered 2 characters)</li>
<li>cf ->invalid input entered, try again</li>
</ul>
<p>ONLY IF THE USER ENTERS CORRECTLY ONE OF THE 3 SIMPLE CHARACTERS (r,c,t NONSENSITIVE CASE) to do sth. Otherwise a massage for invalid input should be printed and then the main menu should appear again</p>
<p>I tried this but it doesnt work:</p>
<pre><code>char displayMainMenu()
{
char mainMenuChoice;
cout << "\nQuadratic equation: a*X^2 + b*X + c = 0 main menu: ";
cout << "\n <r> Give new coefficients";
cout << "\n <c> Calculate equations solutions";
cout << "\n <t> Terminate the program";
cout<<"Enter choice : ";
cin>>mainMenuChoice;
return mainMenuChoice;
}
int main()
{
bool done = false;
while(!done)
{
char choice = displayMainMenu();
if( isalpha(choice) )
{
switch(tolower(choice))
{
case 'r':
DoSTH1();
break;
case 'c':
DoSTH2();
break;
case 't':
DoSTH3();
break;
default:
cout<<"Invalid choice!\n"<<endl;
}
}
}
return 0;
}
</code></pre>
<p>I hope u can help me</p>
<p>ADDED:
When i enter by mistake for example: cbbbbbb
it takes it as if it was 'c'</p>

<p>I know most of the ins and outs of Python's approach to private variables/members/functions/...</p>
<p>However, I can't make my mind up on how to distinguish between methods for external use or subclassing use.</p>
<p>Consider the following example:</p>
<pre><code>class EventMixin(object):
def subscribe(self, **kwargs):
'''kwargs should be a dict of event -> callable, to be specialized in the subclass'''
def event(self, name, *args, **kwargs):
...
def _somePrivateMethod(self):
...
</code></pre>
<p>In this example, I want to make it clear that subscribe is a method to be used by external users of the class/object, while event is a method that should not be called from the outside, but rather by subclass implementations.</p>
<p>Right now, I consider both part of the public API, hence don't use any underscores. However, for this particular situation, it would feel cleaner to, for example, use no underscores for the external API, one underscore for the subclassable API, and two underscores for the private/internal API. However, that would become unwieldy because then the internal API would need to be invoked as</p>
<pre><code>self._EventMixin__somePrivateMethod()
</code></pre>
<p>So, what are your conventions, coding-wise, documentationwise, or otherwise ?</p>

<p>I have a web application that makes heavy use of the Session state to store information about the current user, their personal settings, record their session history and so on. </p>
<p>I have found myself retrieving this session information in my business layer, like so:</p>
<pre><code>((UserSession)HttpContext.Current.Session["UserSession"]).User.Info
</code></pre>
<p>This poses a problem - at some point in the future my application will have a Windows client which obviously cannot reference the web Session state. So I need a host or customized session class that I can reference in my business layer that is agnostic of whether the application is running on the web or desktop. Something like:</p>
<pre><code>IHost.User.Info
</code></pre>
<p>Behind the scenes, the web implementation will obviously utilize the Session state to store information, but I need to hide this away from my business layer. Has anyone solved this problem or got any practival advice on how best to approach this?</p>
<p>Help appreciated. </p>

<p>I have a web application that requires a server based component to periodically access POP3 email boxes and retrieve emails. The service then needs to process the emails which will involve:</p>
<ul>
<li>Validating the email against some business rules (does it contain a valid reference in the subject line, which user sent the mail, etc.)</li>
<li>Analysing and saving any attachments to disk</li>
<li>Take the email body and attachment details and create a new item in the database</li>
<li>Or update an existing item where the reference matches the incoming email subject line</li>
</ul>
<p>What is the best way to approach this? I really don't want to have to write a POP3 client from scratch, but I need to be able to customize the processing of emails. Ideally I would be able to plug in some component that does the access and retrieval for me, returning arrays of attachments, body text, subject line, etc. ready for my processing...</p>
<p><strong>[ UPDATE: Reviews ]</strong></p>
<p>OK, so I have spent a fair amount of time looking into (mainly free) .NET POP3 libraries so I thought I'd provide a short review of some of those mentioned below and a few others:</p>
<ul>
<li><a href="http://weblogs.shockbyte.com.ar/rodolfof/archive/2008/07/07/pop3.net-library.aspx" rel="noreferrer">Pop3.net</a> - free - works OK, very basic in terms of functionality provided. This is pretty much just the POP3 commands and some base64 encoding, but it's very straight forward - probably a good introduction</li>
<li><a href="http://www.componentsource.com/products/seekford-net-pop3-wizard/index.html" rel="noreferrer">Pop3 Wizard</a> - commercial / some open source code - couldn't get this to build, missing DLLs, I wouldn't bother with this </li>
<li><a href="http://www.codeplex.com/csharpmail" rel="noreferrer">C#Mail</a> - free for personal use - works well, comes with Mime parser and SMTP client, however the comments are in Japanese (not a big deal) and it didn't work with SSL 'out of the box' - I had to change the SslStream constructor after which it worked no problem</li>
<li><a href="http://sourceforge.net/projects/hpop/" rel="noreferrer">OpenPOP</a> - free - hasn't been updated for about 5 years so it's current state is .NET 1.0, doesn't support SSL but that was no problem to resolve - I just replaced the existing stream with an SslStream and it worked. Comes with Mime parser.</li>
</ul>
<p>Of the free libraries, I'd go for C#Mail or OpenPOP.</p>
<p>I looked at a few commercial libraries: <a href="http://www.chilkatsoft.com/" rel="noreferrer">Chillkat</a>, <a href="http://www.rebex.net/" rel="noreferrer">Rebex</a>, <a href="http://remobjects.com/" rel="noreferrer">RemObjects</a>, <a href="http://tech.dimac.net/default2.asp?M=Products/MenuDOTNET.asp&P=Products/JMaildotnet/start.htm" rel="noreferrer">JMail.net</a>. Based on features, price and impression of the company I would probably go for Rebex and may in the future if my requirements change or I run into production issues with either of C#Mail or OpenPOP.</p>
<p>In case anyone's needs it, this is the replacement SslStream constructor that I used to enable SSL with C#Mail and OpenPOP:</p>
<pre><code>SslStream stream = new SslStream(clientSocket.GetStream(), false,
delegate(object sender, X509Certificate cert,
X509Chain chain, SslPolicyErrors errors) { return true; });
</code></pre>

<p>I'm not sure if the title is very clear, but basically what I have to do is read a line of text from a file and split it up into 8 different string variables. Each line will have the same 8 chunks in the same order (title, author, price, etc). So for each line of text, I want to end up with 8 strings.</p>
<p>The first problem is that the last two fields in the line may or may not be present, so I need to do something with stringTokenizer.hasMoreTokens, otherwise it will die messily when fields 7 and 8 are not present.</p>
<p>I would ideally like to do it in one while of for loop, but I'm not sure how to tell that loop what the order of the fields is going to be so it can fill all 8 (or 6) strings correctly. Please tell me there's a better way that using 8 nested if statements! </p>
<p>EDIT: The String.split solution seems definitely part of it, so I will use that instead of stringTokenizer. However, I'm still not sure what the best way of feeding the individual strings into the constructor. Would the best way be to have the class expecting an array, and then just do something like this in the constructor:</p>
<pre><code>line[1] = isbn;
line[2] = title;
</code></pre>

<p>I would be interested to learn about large scale development in Python and especially in how do you maintain a large code base?</p>
<ul>
<li><p>When you make incompatibility changes to the signature of a method, how do you find all the places where that method is being called. In C++/Java the compiler will find it for you, how do you do it in Python?</p></li>
<li><p>When you make changes deep inside the code, how do you find out what operations an instance provides, since you don't have a static type to lookup?</p></li>
<li><p>How do you handle/prevent typing errors (typos)?</p></li>
<li><p>Are UnitTest's used as a substitute for static type checking?</p></li>
</ul>
<p>As you can guess I almost only worked with statically typed languages (C++/Java), but I would like to try my hands on Python for larger programs. But I had a very bad experience, a long time ago, with the clipper (dBase) language, which was also dynamically typed.</p>

<p>I have a web application that comprises the following:</p>
<ul>
<li>A web project (with a web.config file containing a connection string - but no data access code in the web project)</li>
<li>A data access project that uses LINQ-SQL classes to provide entities to the web project UI (this project has a settings file and an app.config - both of which have connection strings)</li>
</ul>
<p>When I build and deploy, there is no settings file or app.config in the Bin directory with the data access .dll, but changing the connection string in the web.config file doesn't change the database accordingly - so the connection string must be compiled into the data access dll. </p>
<p>What I need is one config file for my entire deployment - website, data access dlls, everything - that has one connection string which gets used. At the moment there appear to be multiple connection strings getting used or hardcoded all over the place. </p>
<p>How do I best resolve this mess?</p>
<p>Thanks for any help.</p>

<p>I made previously a question:
<a href="https://stackoverflow.com/questions/236354/error-handling-when-taking-user-input">error handling when taking user input</a></p>
<p>and I made the suggested changes:</p>
<pre><code>char displayMainMenu()
{
char mainMenuChoice;
cout << "\nQuadratic equation: a*X^2 + b*X + c = 0 main menu: ";
cout << "\n <r> Give new coefficients";
cout << "\n <c> Calculate equations solutions";
cout << "\n <t> Terminate the program";
cout<<"Enter choice : ";
cin>>mainMenuChoice;
return mainMenuChoice;
}
int main()
{
bool done = false;
while(!done)
{
char choice = displayMainMenu();
switch(tolower(choice))
{
case 'r':
cout<<"Entered case 'r'";
break;
case 'c':
cout<<"Entered case 'c'";
break;
case 't':
cout<<"Entered case 't'";
break;
default:
cout<<"Invalid choice! Try again"<<endl;
}
}
return 0;
}
</code></pre>
<p>The new problem is that if the user enters by mistake lets say "ter" i get the following :( :</p>
<pre><code>Quadratic equation: a*X^2 + b*X + c = 0 main menu:
<r> Give new coefficients
<c> Calculate equations solutions
<t> Terminate the program
Enter choice : ter
Entered case 't'
Quadratic equation: a*X^2 + b*X + c = 0 main menu:
<r> Give new coefficients
<c> Calculate equations solutions
<t> Terminate the program
Enter choice : Invalid choice! Try again
Quadratic equation: a*X^2 + b*X + c = 0 main menu:
<r> Give new coefficients
<c> Calculate equations solutions
<t> Terminate the program
Enter choice : Invalid choice! Try again
</code></pre>
<p>How could I avoid this from happening??</p>

<p>Or is there a chance that the operation will fail?</p>
<p>Thanks.</p>
<p>I chose the wrong term and what I really meant was rounding to 0, not truncation.</p>
<p>The point is, I need to compare the integer part of two doubles and I'm just casting them to int and then using ==, but, as someone pointed out in one of my earlier questions, this could throw an overflow exception if the double can't fit into the integer.</p>
<p>So the question would be 'Is it correct to use the == operator to compare two doubles that have previously been rounded to 0, or should I stick to the casting to int method and catch a possible exception?</p>

<p>The Zend Framework coding standard mentions the following:</p>
<blockquote>
For files that contain only PHP code, the closing tag ("?>") is never permitted. It is not required by PHP, and omitting it prevents the accidental injection of trailing whitespace into the response.
</blockquote>
<ul>
<li><a href="http://framework.zend.com/manual/en/coding-standard.php-file-formatting.html" rel="noreferrer">Zend Framework coding standard: file formatting</a></li>
</ul>
<p>However I do remember hearing about an issue (with tooling or including maybe?) where files needed to have closing tag.</p>
<p>Does anyone know of any issues (other than the developer issue of wanting symmetry) where you would need to have closing tags or are they generally a bad idea?</p>

<p>I'd like to do the same in C#. Is there anyway of using properties in C# with parameters in the same way I've done with the parameter 'Key' in this VB.NET example?</p>
<blockquote>
<pre><code>Private Shared m_Dictionary As IDictionary(Of String, Object) = New Dictionary(Of String, Object)
</code></pre>
</blockquote>
<pre><code>Public Shared Property DictionaryElement(ByVal Key As String) As Object
Get
If m_Dictionary.ContainsKey(Key) Then
Return m_Dictionary(Key)
Else
Return [String].Empty
End If
End Get
Set(ByVal value As Object)
If m_Dictionary.ContainsKey(Key) Then
m_Dictionary(Key) = value
Else
m_Dictionary.Add(Key, value)
End If
End Set
End Property
</code></pre>

<p>I want to be able to selectively copy a list of files and preserve their directory structure. The problem is that there are quite a few files that their path exceeds 256 character. How is this problem usually handled?</p>
<p>Edit:
I should make it clear that I only want to selectively copy files, not folders. I don't think robocopy can be efficiently used to copy an individual file and it's folder structure effectively.</p>

<p>I built an application which displays the records from database in the window and checks the the database for new records every couple of seconds. The problem is that the window blinks each time I check for new records and I want to fix it. I have tried to compare the old datatable with the new one and refresh only if they are different.
Does anyone know what is the best practice for such cases? I tried to do it the following way but it doesn't work:</p>
<pre><code>private bool GetBelongingMessages()
{
bool result = false;
DataTable dtTemp = OleDbWorks.GetBelongingMessages(currentCallID);
if(dtTemp != dtMessages)
{
dtMessages = dtTemp;
result = true;
}
else

<p>Given an EmployeeId, how can I construct a Linq to Sql query to find all of the ancestors of the employee? Each EmployeeId has an associated SupervisorId (see below).</p>
<p>For example, a query of the ancestors for EmployeeId 6 (Frank Black) should return Jane Doe, Bob Smith, Joe Bloggs, and Head Honcho.</p>
<p>If necessary, I can cache the list of all employees to improve performance.</p>
<p><strong>UPDATE:</strong></p>
<p>I've created the following crude method to accomplish the task. It traverses the employee.Supervisor relationship all the way to the root node. However, this will issue one database call for each employee. Anyone have a more succinct or more performant method? Thanks.</p>
<pre><code>private List<Employee> GetAncestors(int EmployeeId)
{
List<Employee> emps = new List<Employee>();
using (L2STestDataContext dc = new L2STestDataContext())
{
Employee emp = dc.Employees.FirstOrDefault(p => p.EmployeeId == EmployeeId);
if (emp != null)
{
while (emp.Supervisor != null)
{
emps.Add(emp.Supervisor);
emp = emp.Supervisor;
}
}
}
return emps;
}
</code></pre>

<p>How to do svn update of multiple files located across different directories ? </p>
<p>For committing multiple files from different directories, we can put them all up in a text file and give that file as an argument to svn commit and it will happily commit all those files. But <b>update</b> ?</p>
<p><b>EDIT:</b> Mr. Fooz's answer is definitely an option whereby I can create a .bat or .sh file with all the svn updates. But I would like to know if there are any special arguments that svn provide that can be used instead of a file with loads of svn update commands in it. Please note that the file that is used by svn commit contains <i>only</i> the filenames and no svn commands. </p>

<p>How can I create a Unit Test to be sure that my object is safely serializable?</p>

<p>I may be in the minority here, but I very much enjoy <a href="https://perldoc.perl.org/perlform" rel="nofollow noreferrer">Perl's formats</a>. I especially like being able to wrap a long piece of text within a column ("~~ ^<<<<<<<<<<<<<<<<" type stuff). Are there any other programming languages that have similar features, or libraries that implement similar features? I am especially interested in any libraries that implement something similar for Ruby, but I'm also curious about any other options.</p>

<p>I have a web page that displays a long line graph inside a div with overflow-x: scroll.
This works well as a web page allowing the use to scroll back and forward through the graph.</p>
<p>However, when printing the page the scroll position is reset to zero.
Is there a way to overcome this?</p>

<p>I have been slowly learning SQL the last few weeks. I've picked up all of the relational algebra and the basics of how relational databases work. What I'm trying to do now is learn how it's implemented.</p>
<p>A stumbling block I've come across in this, is foreign keys in MySQL. I can't seem to find much about the other than that they exist in the <a href="http://en.wikipedia.org/wiki/InnoDB" rel="noreferrer">InnoDB</a> storage schema that MySQL has.</p>
<p>What is a simple example of foreign keys implemented in MySQL?</p>
<p>Here's part of a schema I wrote that doesn't seem to be working if you would rather point out my flaw than show me a working example.</p>
<pre><code>CREATE TABLE `posts` (
`pID` bigint(20) NOT NULL auto_increment,
`content` text NOT NULL,
`time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
`uID` bigint(20) NOT NULL,
`wikiptr` bigint(20) default NULL,
`cID` bigint(20) NOT NULL,
PRIMARY KEY (`pID`),
Foreign Key(`cID`) references categories,
Foreign Key(`uID`) references users
) ENGINE=InnoDB;
</code></pre>

<p>I have an IList of type Breadcrumb which is just a lightweight class that has NavigationTitle, NavigationUrl and IsCurrent properties. It is cached on the webserver. I have a method that builds out the current breadcrumb trail up until the first Breadcrumb that has IsCurrent set to true... using the code below. Its very ugly and definitely a quick dirtbag willie solution, but I was curious, can this be easily refactored into LINQ? </p>
<pre><code>IList<Breadcrumb> crumbs = new List<Breadcrumb>();
bool foundCurrent = false;
for (int a = 0; a < cachedCrumbs.Count; a++)
{
crumbs.Add(crumbs[a]);
if (foundCurrent)
{
break;
}
foundCurrent = (crumbs[a + 1] != null && ((Breadcrumb)crumbs[a + 1]).IsCurrent);
}
</code></pre>

<p>I have a device that supports 4-color graphics (much like CGA in the old days).</p>
<p>I wanted to use <a href="http://www.pythonware.com/products/pil/" rel="noreferrer">PIL</a> to read the image and convert it using my 4-color palette (of red, green, yellow, black), but I can't figure out if it's even possible at all. I found some mailing list archive posts that seem to suggest other people have tried to do so and failed.</p>
<p>A simple python example would be much appreciated!</p>
<p>Bonus points if you add something that then converts the image to a byte string where each byte represents 4 pixels of data (with each two bits representing a color from 0 to 3)</p>

<p>I am using Ruby on Rails.</p>
<p>I want to create a filter field on a page such that whenever the input field's value changes I filter a list shown below via ajax. (Exaclty like the Users search works in Stackoverflow)</p>
<p>For now, I made it run with a form_remote_tag containing a text_field_tag and a submit_tag, and it filters my list when I push the submit button. I would like to remove the submit button and execute the filtering every time the value of the text input changes. How can I trigger a form submit every time the text in an input field changes?</p>
<p>I tried inside my form</p>
<p><code><%= text_field_tag (:filter), "" , :onchange => "alert ('This is a Javascript Alert')" %></code></p>
<p>just to get the onchange event, but somehow not even this alert appears...</p>

<p>Perl and PHP do this with backticks. For example,</p>
<pre><code>$output = `ls`;
</code></pre>
<p>Returns a directory listing. A similar function, <code>system("foo")</code>, returns the operating system return code for the given command foo. I'm talking about a variant that returns whatever foo prints to stdout.</p>
<p>How do other languages do this? Is there a canonical name for this function? (I'm going with "backtick"; though maybe I could coin "syslurp".)</p>
