<p>Why isn't Visual Studio 2005 generating a serialization setting when I set the project setting "Generate Serialization Assembly" to "On"?</p>

<p>I am trying to set the disabled font characteristics for a Label Control. I can set all of the Font characteristics (size, bold, etc), but the color is overridden by the default windows behavior which seems to be one of these two colors:</p>
<ul>
<li>If background color is transparent then ForeColor is same as TextBox disabled Color.</li>
<li>If background color is set to anything else, ForeColor is a Dark Gray color.</li>
</ul>
<p>The image below demonstrates the behavior -- Column 1 is Labels, Column 2 is TextBoxs, and Column 3 is ComboBoxes.</p>
<p><img src="https://i.stack.imgur.com/60viN.png" alt="alt text"></p>
<p>Edit -- Explaining the image: The first two rows are default styles for a label, textbox, and combobox. In the second two rows, I set the Background color to Red and Foreground to White. The disabled font style handling by Microsoft is inconsistent.</p>

<p>I need to create and copy to the clipboard some RichText with standard "formatting" like bold/italics, indents and the like. The way I'm doing it now seems kind of inelegant... I'm creating a RichTextBox item and applying my formatting through that like so:</p>
<pre><code>RichTextBox rtb = new RichTextBox();
Font boldfont = new Font("Times New Roman", 10, FontStyle.Bold);
rtb.Text = "sometext";
rtb.SelectAll()
rtb.SelectionFont = boldfont;
rtb.SelectionIndent = 12;
</code></pre>
<p>There has got to be a better way, but after a few hours of searching I was unable to come up with anything better. Any ideas?</p>
<p>Edit:
The RichTextBox (rtb) is not displayed/drawn anywhere on a form. I'm just using the object to format my RichText.</p>

<p>I'm writing a log file viewer for a web application and for that I want to paginate through the lines of the log file. The items in the file are line based with the newest item at the bottom.</p>
<p>So I need a <code>tail()</code> method that can read <code>n</code> lines from the bottom and support an offset. This is hat I came up with:</p>
<pre><code>def tail(f, n, offset=0):
"""Reads a n lines from f with an offset of offset lines."""
avg_line_length = 74
to_read = n + offset
while 1:
try:
f.seek(-(avg_line_length * to_read), 2)
except IOError:
# woops. apparently file is smaller than what we want
# to step back, go to the beginning instead
f.seek(0)
pos = f.tell()
lines = f.read().splitlines()
if len(lines) >= to_read or pos == 0:
return lines[-to_read:offset and -offset or None]
avg_line_length *= 1.3
</code></pre>
<p>Is this a reasonable approach? What is the recommended way to tail log files with offsets?</p>

<p>I have a single-threaded application that loads several assemblies at runtime using the following:</p>
<pre><code>objDLL = Assembly.LoadFrom(strDLLs[i]);
</code></pre>
<p>I would like the assemblies loaded in this manner to use the same log4net.ILog reference as the rest of the assemblies do. But it appears the runtime loaded assemblies have a different reference altogether and need their own configuration. Does anyone know if a single log4net.ILog can be used across assemblies loaded at runtime using a .NET interface?</p>
<p>Here is the log4net.ILog creation and supporting code in the Program class:</p>
<pre><code> // Configure log4net using the .config file
[assembly: log4net.Config.XmlConfigurator(Watch = true)]
public static class Program
{
private static log4net.ILog m_Log = null;
[STAThread]
public static void Main(string[] args)
{
try
{
m_Log = log4net.LogManager.GetLogger(
MethodBase.GetCurrentMethod().DeclaringType);
}
}
}
</code></pre>

<p>My app keeps track of the state of about 1000 objects. Those objects are read from and written to a persistent store (serialized) in no particular order. </p>
<p>Right now the app uses the registry to store each object's state. This is nice because:</p>
<ul>
<li><p>It is simple</p></li>
<li><p>It is very fast</p></li>
<li><p>Individual object's state can be read/written without needing to read some larger entity (like pulling out a snippet from a large XML file)</p></li>
<li><p>There is a decent editor (RegEdit) which allow easily manipulating individual items</p></li>
</ul>
<p>Having said that, I'm wondering if there is a better way. SQLite seems like a possibility, but you don't have the same level of multiple-reader/multiple-writer that you get with the registry, and no simple way to edit existing entries.</p>
<p>Any better suggestions? A bunch of flat files?</p>

<p>I'm running <a href="http://www.git-scm.com/docs/git-diff" rel="noreferrer">git-diff</a> on a file, but the change is at the end of a long line.</p>
<p>If I use cursor keys to move right, it loses colour-coding—and worse the lines don't line up—making it harder to track the change.</p>
<p>Is there a way to prevent that problem or to simply make the lines wrap instead?</p>
<p>I'm running Git 1.5.5 via mingw32.</p>

<p>Let's say I want to write a regular expression to change all <code><abc></code>, <code><def></code>, and <code><ghi></code> tags into <code><xyz></code> tags.. and I also want to change their closing tags to <code></xyz></code>. This seems like a reasonable regex (ignore the backticks; StackOverflow has trouble with the less-than signs if I don't include them):</p>
<pre><code>`s!<(/)?(abc|def|ghi)>!<${1}xyz>!g;`
</code></pre>
<p>And it works, too. The only problem is that for opening tags, the optional $1 variable gets assigned undef, and so I get a "Use of uninitialized value..." warning.</p>
<p>What's an elegant way to fix this? I'd rather not make this into two separate regexs, one for opening tags and another for closing tags, because then there are two copies of the taglist that need to be maintained, instead of just one.</p>
<p><strong>Edit:</strong> I know I could just turn off warnings in this region of the code, but I don't consider that "elegant".</p>

<p>We have a windows application that contains an ActiveX WebBrowser control. As part of the regular operation of this application modifications are made to the pages that are displayed by the ActiveX WebBrowser control. Part of these modifications involve setting a JavaScript variable in a web page being loaded into the ActiveX WebBrowser. </p>
<p>We need to initialize this variable within C# (originally, VB6 code was initializing the value). The value of this variable is a COM-visible class object. </p>
<p>However, for simplicity we've reduced the problem to setting a string value. Our original page involves frames and the like but the same problems happens in a page like this:</p>
<pre><code><HTML>
<HEAD>
<TITLE>Test</TITLE>
<SCRIPT type="text/javascript">
var field = 'hello world';
</SCRIPT>
</HEAD>
<BODY>
<input type="button" value="See field" onclick="javascript:alert(field);"/>
</BODY>
</HTML>
</code></pre>
<p>We want to access the <em>field</em> variable and assign a value to it. In VB6 the code for this was pretty straightforward:</p>
<pre><code>doc.Script.field = 'newValue'
</code></pre>
<p>However, in C# we've had to resort to other tricks, like this: </p>
<pre><code>Microsoft.VisualBasic.CompilerServices.NewLateBinding.LateSet(Script, null, "field",new object[] { "newValue"},null, null);
</code></pre>
<p>The point of the page is to test whether our variable was properly assigned by C#. Clicking on the button should yield whatever new value was injected by C#. So for example, clicking on the button in the page we get an alert showing: "newValue".</p>
<p>That works the first time, but it doesn't work if we reload the page. On subsequent calls we cannot set the value of the variable <code>field</code>. </p>
<p>Has anyone had any experience doing this type of operation before?</p>

<p>Not really getting the point of the map function. Can anyone explain with examples its use?</p>
<p>Are there any performance benefits to using this instead of a loop or is it just sugar?</p>

<p>in tcsh I'm trying to redirect STDERR from a command from my .aliases file.</p>
<p>I found that I can redirect STDERR from the command line like this. . .</p>
<pre><code>$ (xemacs > /dev/tty) >& /dev/null
</code></pre>
<p>. . . but when I put this in my .aliases file I get an alias loop. . .</p>
<pre><code>$ cat .aliases
alias xemacs '(xemacs > /dev/tty ) >& /dev/null'
$ xemacs &
Alias loop.
$
</code></pre>
<p>. . . so I put a backslash before the command in .aliases, which allows the command to run. . .</p>
<pre><code>$ cat .aliases
alias xemacs '(\xemacs > /dev/tty ) >& /dev/null'
$ xemacs &
[1] 17295
$
</code></pre>
<p>. . . but now I can't give the command any arguments:</p>
<pre><code>$ xemacs foo.txt &
Badly placed ()'s.
[1] Done ( \xemacs > /dev/tty ) >& /dev/null
$
</code></pre>
<p>Can anyone offer any solutions? Thank you in advance!</p>
<hr>
<p>UPDATE: I'm still curious if it's possible to redirect STDERR in tcsh from .aliases, but as has been suggested here, I ended up with a shell script:</p>
<pre><code>#!/bin/sh
# wrapper script to suppress messages sent to STDERR on launch
# from the command line.
/usr/bin/xemacs "$@" 2>/dev/null
</code></pre>

<p>The reason I want to do this is to make it easy to parse out instructions that are emailed to a bot, the kind of thing majordomo might do to parse commands like subscribing and unsubscribing. It turns out there are a lot of crazy formats and things to deal with, like quoted text, distinguishing between header and body, etc.</p>
<p>A perl module to do this would be ideal but solutions in any language are welcome.</p>

<p>I have a Windows Form app written in C#. Its job is to send messages to a list of users. While those messages are being sent, I'd like to display status of the operation for each user. What I am doing (for each user) is creating a Label control and adding it to Panel. This works without a problem for a small set of users. When I increase the size to 1000 or more, the Visual Studio Debugger displays the following message:</p>
<blockquote>
<p><em>A first chance exception of type 'System.ComponentModel.Win32Exception' occurred in
System.Windows.Forms.dll A first chance exception of type
'System.Reflection.TargetInvocationException' occurred in
mscorlib.dll</em></p>
</blockquote>
<p>And then the application hangs. Any thoughts on what I'm doing wrong and how I can fix this?</p>

<p>For example, I rarely need:</p>
<pre><code>using System.Text;
</code></pre>
<p>but it's always there by default. I assume the application will use more memory if your code contains unnecessary <a href="http://msdn.microsoft.com/en-us/library/aa664764(VS.71).aspx" rel="noreferrer">using directives</a>. But is there anything else I should be aware of?</p>
<p>Also, does it make any difference whatsoever if the same using directive is used in only one file vs. most/all files?</p>

<p>I have this PHP code that I am trying to use to let a user edit a news record in a form and then when they hit the submit button, it will update the record in a database. The problem is that everything works but the record is not actually updated in the database.</p>
<p>Could someone look at my code and see where a problem could occur?</p>
<pre><code><?php
$title = "Edit News";
include("../includes/header.php");
include("../includes/database.php");
$done = false;
$expected = array('newstitle', 'newscontent', 'id');
if ($_GET && !$_POST) {
if (isset($_GET['id']) && is_numeric($_GET['id'])) {
$id = $_GET['id'];
}
else {
$id = NULL;
}
if ($id) {
$sql = "SELECT * FROM news WHERE id = $id";
$result = mysql_query($sql) or die ("Error connecting to database...");
$row = mysql_fetch_assoc($result);
}
// if form has been submitted, update record
if (array_key_exists('update', $_POST)) {
// prepare expected items for insertion into database
foreach ($_POST as $key => $value) {
if (in_array($key, $expected)) {
${$key} = mysql_real_escape_string($value);
}
}
// abandon the process if primary key invalid
if (!is_numeric($id)) {
die('Invalid request');
}
// prepare the SQL query
$query = "UPDATE news SET title = '$title', content = '$content' WHERE id = $id";
// submit the query
$done = mysql_query($query) or die("Error connecting to database...");
}
}
// redirect page if $id is invalid
if ($done) {
header("Location: $ROOT/admin/listnews.php");
exit;
}
?>
</code></pre>

<p>We recently started using maven for dependency management. Our team uses eclipse as it's IDE. Is there an easy way to get eclipse to refresh the maven dependencies without running mvn eclipse:eclipse?</p>
<p>The dependencies are up to date in the local maven repository, but eclipse doesn't pick up the changes until we use the eclipse:eclipse command. This regenerates a lot of eclipse configuration files.</p>

<p>Right now, I have two Eclipse projects - they both use Maven 2 for all their jar-dependency goodness.</p>
<p>Inside Eclipse, I have project Foo included in project Bar's build path, so that I can use Foo's classes from project Bar. This works really well in Eclipse land, but when I try:</p>
<pre><code>mvn compile
</code></pre>
<p>inside Bar's directory, it fails because Maven doesn't know about the project-to-project relationship in Eclipse's build path.</p>
<p>If I were using Ant, I would just use it to do something silly like copy foo.jar into project Bar's classpath, but as far as I can tell, things are done a lot less hackishly in Maven-land.</p>
<p>I'm wondering if there's a standard workaround for this type of problem - it seems like it would be fairly common, and I'm just missing something basic about how Maven works.</p>

<p>This could be weird, Have you ever come across a blog which you wanted to read in the chronological order? And that blog could be old, with several hundred posts. When i add this feed to my feed reader, say googlereader, the latest feed comes on top and as i scroll down further, the older posts appear. This could be frustrating if you want to read it from the beginning. Is there any reader that does this? Or, i would love to do this as a pet project, (preferably in c#), how exactly should i go about it? Also, are there any .NET libraries which i can use to work on RSS feeds? I have not done any RSS feed programming before.</p>
<p><strong>EDIT</strong> I would like to know if there are any technical limitations to this. This was jsut one interesting problem that I encountered that i thought could be tackled programmatically.</p>

<p>I have a Flex application where I'm using a Canvas to contain several other components. On that Canvas there is a Button which is used to invoke a particular flow through the system. Clicking anywhere else on the Canvas should cause cause a details pane to appear showing more information about the record represented by this control.</p>
<p>The problem I'm having is that because the button sits inside the Canvas any time the user clicks the Button the click event is fired on both the Button and the Canvas. Is there any way to avoid having the click event fired on the Canvas object if the user clicks on an area covered up by another component?</p>
<p>I've created a simple little test application to demonstrate the problem:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
<![CDATA[
private function onCanvasClick(event:Event):void {
text.text = text.text + "\n" + "Canvas Clicked";
}
private function onButtonClick(event:Event):void {
text.text = text.text + "\n" + "Button Clicked";
}
]]>
</mx:Script>
<mx:Canvas x="97" y="91" width="200" height="200" backgroundColor="red" click="onCanvasClick(event)">
<mx:Button x="67" y="88" label="Button" click="onButtonClick(event)"/>
</mx:Canvas>
<mx:Text id="text" x="97" y="330" text="Text" width="200" height="129"/>
</mx:Application>
</code></pre>
<p>As it stands when you click the button you will see two entries made in the text box, "Button Clicked" followed by "Canvas Clicked" even though the mouse was clicked only once.</p>
<p>I'd like to find a way that I could avoid having the second entry made such that when I click the Button only the "Button Clicked" entry is made, but if I were to click anywhere else in the Canvas the "Canvas Clicked" entry would still appear.</p>

<p>I need to determine the current year in Java as an integer. I could just use <code>java.util.Date()</code>, but it is deprecated.</p>

<p>I have a PHP script that is called from a cron job every minute. This script takes some info from the database and then calls another PHP script using the System function (passing it some parameters).</p>
<p>That means that I can start up to 10 scripts from this "main" one. And what I would like to do is that I would call the script and continue the execution of the main script, that is, not wait for the System call to complete and then call the next one. </p>
<p>How can this be done?</p>

<p>I have a client/server system that performs communication using XML transferred using HTTP requests and responses with the client using Perl's LWP and the server running Perl's CGI.pm through Apache. In addition the stream is encrypted using SSL with certificates for both the server and all clients.</p>
<p>This system works well, except that periodically the client needs to send really large amounts of data. An obvious solution would be to compress the data on the client side, send it over, and decompress it on the server. Rather than implement this myself, I was hoping to use Apache's mod_deflate's "Input Decompression" as described <a href="http://httpd.apache.org/docs/2.0/mod/mod_deflate.html" rel="nofollow noreferrer">here</a>.</p>
<p>The description warns:</p>
<blockquote>
<p>If you evaluate the request body yourself, don't trust the Content-Length header! The Content-Length header reflects the length of the incoming data from the client and not the byte count of the decompressed data stream.</p>
</blockquote>
<p>So if I provide a Content-Length value which matches the compressed data size, the data is truncated. This is because mod_deflate decompresses the stream, but CGI.pm only reads to the Content-Length limit.</p>
<p>Alternatively, if I try to outsmart it and override the Content-Length header with the decompressed data size, LWP complains and resets the value to the compressed length, leaving me with the same problem.</p>
<p>Finally, I attempted to hack the part of LWP which does the correction. The original code is:</p>
<pre><code> # Set (or override) Content-Length header
my $clen = $request_headers->header('Content-Length');
if (defined($$content_ref) && length($$content_ref)) {
$has_content = length($$content_ref);
if (!defined($clen) || $clen ne $has_content) {
if (defined $clen) {
warn "Content-Length header value was wrong, fixed";
hlist_remove(\@h, 'Content-Length');
}
push(@h, 'Content-Length' => $has_content);
}
}
elsif ($clen) {
warn "Content-Length set when there is no content, fixed";
hlist_remove(\@h, 'Content-Length');
}
</code></pre>
<p>And I changed the push line to:</p>
<pre><code> push(@h, 'Content-Length' => $clen);
</code></pre>
<p>Unfortunately this causes some problem where content (truncated or not) doesn't even get to my CGI script.</p>
<p>Has anyone made this work? I found <a href="http://hype-free.blogspot.com/2007/07/compressed-http.html" rel="nofollow noreferrer">this</a> which does compression on a file before uploading, but not compressing a generic request.</p>

<p>How to allow <code>TextBlock</code>'s text to be selectable?</p>
<p>I tried to get it to work by displaying the text using a read-only TextBox styled to look like a textblock but this will not work in my case because a TextBox does not have inlines. In other words, how to make it selectable?</p>

<p>I am developing an auto-builder that will run a series of steps in our build process and build our target application. We used to use a batch file which set up a bunch of environment variables or called tools that setup environment variables and ultimately runs a 'make'. </p>
<p>I've been using the 'Process' class which works great for running those commands but unfortunately every time one runs which makes changes to the environment (like adding something to the PATH) those variables are lost when the 'Process' completes. The next 'Process' is instantiated and inherits the env from the 'calling' app (my exe) again - which means all env setup by the last command are lost. How do you handle this situation? Is there a better way to run a series of batch-file like commands within C# and maintain the environment they set up?</p>
<p>Please note that unfortunately the old-schoolers have declared that nant/ant are not an option so "Hey, why not use Nant - it does that!" is not the answer I am looking for. </p>
<p>Thanks.</p>

<p>We've noticed that IE7 has an odd behavor with code blocks posted on Stack Overflow. For example, this little code block:</p>
<pre><code>public PageSizer(string href, int index)
{
HRef = href;
PageIndex = index;
}
</code></pre>
<p>Copy and pasted from IE7, ends up like this:</p>
<pre>
public PageSizer(string href, int index){ HRef = href; PageIndex = index; }
</pre>
<p>Not exactly what we had in mind.. the underlying HTML source actually looks fine; if you View Source, you'll see this:</p>
<pre><code><pre><code>public PageSizer(string href, int index)
{
HRef = href;
PageIndex = index;
}
</code></pre>
</code></pre>
<p>So what are we doing wrong? Why can't IE7 copy and paste this HTML in a rational way?</p>
<blockquote>
<p>Update: <strong>this specifically has to do with <code><pre></code> <code><code></code> blocks that are being modified at runtime via JavaScript.</strong> The native HTML does render and copy correctly; it's the JavaScript modified version of that HTML which doesn't behave as expected. Note that copying and pasting into WordPad or Word works because IE is putting different content in the rich text clipboard compared to the plain text clipboard that Notepad gets its data from.</p>

<p>How would I have a <a href="http://en.wikipedia.org/wiki/JavaScript" rel="noreferrer">JavaScript</a> action that may have some effects on the current page but would also change the URL in the browser so if the user hits reload or bookmark, then the new URL is used? </p>
<p>It would also be nice if the back button would reload the original URL.</p>
<p>I am trying to record JavaScript state in the URL.</p>

<p>short:</p>
<p>Is there a way in Ruby to DRY-ify this:</p>
<pre><code>def entry_point_one
begin
do_something
rescue MySyntaxErrorOne, MySyntaxErrorTwo, MySyntaxErrorEtc => syn_err
raise syn_err.exception(syn_err.message)
end
end
def entry_point_two
begin
do_something_else
rescue MySyntaxErrorOne, MySyntaxErrorTwo, MySyntaxErrorEtc => syn_err
raise syn_err.exception(syn_err.message)
end
end
</code></pre>
<p>longer:</p>
<p>I'm building an interpreter. This interpreter can be called using different entry points. If I feed this interpreter a 'dirty' string, I expect it to raise an error. However, it would be nice if I don't get spammed by the by the entire back trace of every method called directly or indirectly by do_something, especially since the interpreter makes use of recursion.</p>
<p>As you can see in the above snippet, I already know a way to re raise an error and thereby removing the back trace. What I would like do is remove the duplication in the above example. The closest I have come thus far is this:</p>
<pre><code>def entry_point_one
re_raise_known_exceptions {do_something}
end
def entry_point_two
re_raise_known_exceptions {do_something_else}
end
def re_raise_known_exceptions
yield
rescue MySyntaxErrorOne, MySyntaxErrorTwo, MySyntaxErrorEtc => syn_err
raise syn_err.exception(syn_err.message)
end
</code></pre>
<p>But that makes the method re-raise-known-exceptions show up in the back trace.</p>
<p>edit: I guess what I want would be something like a C pre-processing macro</p>

<p>I have a set of objects in a Vector from which I'd like to select a random subset (e.g. 100 items coming back; pick 5 randomly). In my first (very hasty) pass I did an extremely simple and perhaps overly clever solution:</p>
<pre><code>Vector itemsVector = getItems();
Collections.shuffle(itemsVector);
itemsVector.setSize(5);
</code></pre>
<p>While this has the advantage of being nice and simple, I suspect it's not going to scale very well, i.e. Collections.shuffle() must be O(n) at least. My less clever alternative is</p>
<pre><code>Vector itemsVector = getItems();
Random rand = new Random(System.currentTimeMillis()); // would make this static to the class
List subsetList = new ArrayList(5);
for (int i = 0; i < 5; i++) {
// be sure to use Vector.remove() or you may get the same item twice
subsetList.add(itemsVector.remove(rand.nextInt(itemsVector.size())));
}
</code></pre>
<p>Any suggestions on better ways to draw out a random subset from a Collection?</p>

<p>I have a string in a node and I'd like to split the string on '?' and return the last item in the array.</p>
<p>For example, in the block below:</p>
<pre><code><a>
<xsl:attribute name="href">
/newpage.aspx?<xsl:value-of select="someNode"/>
</xsl:attribute>
Link text
</a>
</code></pre>
<p>I'd like to split the <code>someNode</code> value.</p>
<p>Edit:
Here's the VB.Net that I use to load the Xsl for my Asp.Net page:</p>
<pre><code>Dim xslDocPath As String = HttpContext.Current.Server.MapPath("~/App_Data/someXslt.xsl")
Dim myXsltSettings As New XsltSettings()
Dim myXMLResolver As New XmlUrlResolver()
myXsltSettings.EnableScript = True
myXsltSettings.EnableDocumentFunction = True
myXslDoc = New XslCompiledTransform(False)
myXslDoc.Load(xslDocPath, myXsltSettings, myXMLResolver)
Dim myStringBuilder As New StringBuilder()
Dim myXmlWriter As XmlWriter = Nothing
Dim myXmlWriterSettings As New XmlWriterSettings()
myXmlWriterSettings.ConformanceLevel = ConformanceLevel.Auto
myXmlWriterSettings.Indent = True
myXmlWriterSettings.OmitXmlDeclaration = True
myXmlWriter = XmlWriter.Create(myStringBuilder, myXmlWriterSettings)
myXslDoc.Transform(xmlDoc, argumentList, myXmlWriter)
Return myStringBuilder.ToString()
</code></pre>
<p><strong>Update:</strong> here's <a href="http://gist.github.com/360186" rel="noreferrer">an example of splitting XML on a particular node</a></p>

<p>I'm searching for UUIDs in blocks of text using a regex. Currently I'm relying on the assumption that all UUIDs will follow a patttern of 8-4-4-4-12 hexadecimal digits.</p>
<p>Can anyone think of a use case where this assumption would be invalid and would cause me to miss some UUIDs?</p>

<p>FYI: I am running on dotnet 3.5 SP1</p>
<p>I am trying to retrieve the value of an identity column into my dataset after performing an update (using a SqlDataAdapter and SqlCommandBuilder).
After performing SqlDataAdapter.Update(myDataset), I want to be able to read the auto-assigned value of <code>myDataset.tables(0).Rows(0)("ID")</code>, but it is System.DBNull (despite the fact that the row was inserted).</p>
<p>(Note: I do not want to explicitly write a new stored procedure to do this!)</p>
<p>One method often posted <a href="http://forums.asp.net/t/951025.aspx" rel="noreferrer">http://forums.asp.net/t/951025.aspx</a> modifies the SqlDataAdapter.InsertCommand and UpdatedRowSource like so:</p>
<pre><code>SqlDataAdapter.InsertCommand.CommandText += "; SELECT MyTableID = SCOPE_IDENTITY()"
InsertCommand.UpdatedRowSource = UpdateRowSource.FirstReturnedRecord
</code></pre>
<p>Apparently, this seemed to work for many people in the past, but does not work for me.</p>
<p>Another technique: <a href="http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=619031&SiteID=1" rel="noreferrer">http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=619031&SiteID=1</a> doesn't work for me either, as after executing the SqlDataAdapter.Update, the SqlDataAdapter.InsertCommand.Parameters collection is reset to the original (losing the additional added parameter).</p>
<p>Does anyone know the answer to this???</p>

<p>Is there a way through the .net framework to determine if a folder is shared or not?</p>
<p>Neither Diretory, DirectoryInfo or FileAttributes seem to have any corresponding field.</p>
<p>One thing I forgot to mention was that I want to be checking for network shares. But I'll investigate the WMI stuff.</p>

<p>In C++ you can initialize a variable in an if statement, like so:</p>
<pre><code>if (CThing* pThing = GetThing())
{
}
</code></pre>
<p>Why would one consider this bad or good style? What are the benefits and disadvantages?</p>
<p>Personally i like this style because it limits the scope of the pThing variable, so it can never be used accidentally when it is NULL. However, i don't like that you can't do this:</p>
<pre><code>if (CThing* pThing = GetThing() && pThing->IsReallySomeThing())
{
}
</code></pre>
<p>If there's a way to make the above work, please post. But if that's just not possible, i'd still like to know why.</p>

<p>I'm trying to get an expect script to work, and when I use the -re flag (to invoke regular expression parsing), the 'timeout' keyword seems to no longer work. When the following script is run, I get the message 'timed out at step 1', then 'starting step 2' and then it times out but does NOT print the 'timed out at step 2' I just get a new prompt.</p>
<p>Ideas?</p>
<pre><code>#!/usr/bin/expect --
spawn $env(SHELL)
match_max 100000
set timeout 2
send "echo This will print timed out\r"
expect {
timeout { puts "timed out at step 1" }
"foo " { puts "it said foo at step 1"}
}
puts "Starting test two\r"
send "echo This will not print timed out\r"
expect -re {
timeout { puts "timed out at step 2" ; exit }
"foo " { puts "it said foo at step 2"}
}
</code></pre>

<p>I'm writing an app and our designers want to use gradients for some of the backgrounds on a few of our composites. </p>
<p>I wrote the following code:</p>
<pre><code>composite.addListener (SWT.Paint, new Listener () {
public void handleEvent (Event e) {
GC gc = e.gc;
Rectangle rect = composite.getClientArea ();
Color color1 = new Color (display, 0, 0, 0);
Color color2 = new Color (display, 255, 255, 255);
gc.setForeground(color1);
gc.setBackground(color2);
gc.fillGradientRectangle (rect.x, rect.y, rect.width, rect.height , true);
}
});
</code></pre>
<p>This draws the gradient fine on the composite, but we have Label/CLabels, Canvases and Links on top of the composite. </p>
<p>In these areas, the background is just the plain gray you get when drawing an empty canvas. </p>
<p>I've tried forcing the Labels to inherit the background like so:</p>
<pre><code>label.setBackgroundMode(SWT.INHERIT_DEFAULT) //SWT.INHERIT_FORCE Doesn't work either
</code></pre>
<p>But this leaves me with the same default gray and no gradient behind the components on top of the Composite. </p>
<p>Any suggestions for getting the gradient to be the background of each element?</p>
<p>I wouldn't be opposed to drawing the Gradient onto a gc with an image supplied and then setting the background to that Image. However that method just hasn't been working at all, composite or any of its elements. </p>
<p>Also it's not possible for me to set the gradient individually to my knowledge. We want the whole composite to be one uniform flowing gradient. </p>
<p>[edit] I uploaded an example upto twitpic <a href="http://twitpic.com/d5qz" rel="nofollow noreferrer">here</a>.</p>
<p>Thanks,</p>
<p>Brian Gianforcaro</p>

<p>Sorry if the title is poorly descriptive, but I can't do better right now =(</p>
<p>So, I have this master-detail scheme, with the detail being a tree structure (one to many self relation) with n levels (on SQLServer 2005)</p>
<p>I need to copy a detail structure from one master to the another using a stored procedure, by passing the source master id and the target master id as parameters (the target is new, so it doesn't has details).</p>
<p>I'm having troubles, and asking for your kind help in finding a way to keep track of parent id's and inserting the children without using cursors or nasty things like that...</p>
<p><img src="https://i.stack.imgur.com/hBzdZ.jpg" alt="table model for the problem"></p>
<p>This is a sample model, of course, and what I'm trying to do is to copy the detail structure from one master to other. In fact, I'm creating a new master using an existing one as template.</p>

<p>How do I programmatically force an onchange event on an input?</p>
<p>I've tried something like this:</p>
<pre><code>var code = ele.getAttribute('onchange');
eval(code);
</code></pre>
<p>But my end goal is to fire any listener functions, and that doesn't seem to work. Neither does just updating the 'value' attribute.</p>

<p>I have a model and two views set up like this:</p>
<pre><code>Model ---> OSortFilterProxyModel ---> OListView
Model ------------------------------> OTableView
</code></pre>
<p>When the user selects something in one of the views, I want the other view to mirror that selection. So I thought I'd use a QSelectionModel to link them together. But this does not work. I have a feeling it is because the views think they have two different models, when in fact they have the same model. Is there a way to get this to work?</p>

<p>We have a .NET 2.0 application which we normally run on IIS6, and used to run fine on IIS7, but recently after installing SP1 for Vista IIS7 seems to be choking on a line in the Web.Config file:</p>
<pre><code><system.web AllowLocation="true">
</code></pre>
<p>Is it safe to remove the AllowLocation attribute? What does this attribute do?</p>

<p>How can I compare the content of two (or more) large .resx files? With hundreds of Name/Value pairs in each file, it'd be very helpful to view a combined version. I'm especially interested in Name/Value pairs which are present in the neutral culture but are not also specified in a culture-specific version.</p>

<p>I'm having trouble coming up with the correct regex string to remove a sequence of multiple ? characters. I want to replace more than one sequential ? with a single ?, but which characters to escape...is escaping me.</p>
<p>Example input:</p>
<blockquote>
<p>Is this thing on??? or what???</p>
</blockquote>
<p>Desired output:</p>
<blockquote>
<p>Is this thing on? or what?</p>
</blockquote>
<p>I'm using <a href="http://php.net/preg_replace" rel="nofollow noreferrer">preg_replace()</a> in PHP.</p>

<p>I'd like to log stuff in my Sharepoint Web Parts, but I want it to go into the ULS. Most examples that I've found log into the Event Log or some other file, but I did not really find one yet for logging into the ULS.</p>
<p>Annoyingly, Microsoft.SharePoint.Diagnostics Classes are all marked Internal. I did find <a href="http://www.codeplex.com/SharePointOfView/SourceControl/FileView.aspx?itemId=244213&changeSetId=13835" rel="nofollow noreferrer">one example</a> of how to use them anyway through reflection, but that looks really risky and unstable, because Microsoft may change that class with any hotfix they want.</p>
<p>The Sharepoint Documentation wasn't really helpful either - lots of Administrator info about what ULS is and how to configure it, but i have yet to find an example of supported code to actually log my own events.</p>
<p>Any hints or tips?</p>
<p><strong>Edit:</strong> As you may see from the age of this question, this is for SharePoint 2007. In SharePoint 2010, you can use SPDiagnosticsService.Local and then <a href="http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.administration.spdiagnosticsservicebase.writetrace.aspx" rel="nofollow noreferrer">WriteTrace</a>. See the answer from Jürgen below.</p>

<p>I'm looking for a few talking points I could use to convince coworkers that it's NOT OK to run a 24/7 production application by simply opening Visual Studio and running the app in debug mode.</p>
<p>What's different about running a compiled console application vs. running that same app in debug mode? </p>
<p>Are there ever times when you would use the debugger in a live setting? (live: meaning connected to customer facing databases)</p>
<p>Am I wrong in assuming that it's always a bad idea to run a live configuration via the debugger? </p>

<p>I've got a code like this : </p>
<pre><code>Dim Document As New mshtml.HTMLDocument
Dim iDoc As mshtml.IHTMLDocument2 = CType(Document, mshtml.IHTMLDocument2)
iDoc.write(html)
iDoc.close()
</code></pre>
<p>However when I load an HTML like this it executes all Javascripts in it as well as doing request to some resources from "html" code.</p>
<p>I want to disable javascript and all other popups (such as certificate error).</p>
<p>My aim is to use DOM from mshtml document to extract some tags from the HTML in a reliable way (instead of bunch of regexes). </p>
<p>Or is there another IE/Office DLL which I can just load an HTML wihtout thinking about IE related popups or active scripts?</p>

<p>I have a Hashtable<Integer, Sport> called sportMap and a list of sportIds (List<Integer> sportIds) from my backing bean. The Sport object has a List<String> equipmentList. Can I do the following using the unified EL to get the list of equipment for each sport?</p>
<pre><code><h:dataTable value="#{bean.sportIds}" var="_sportId" >
<c:forEach items="#{bean.sportMap[_sportId].equipmentList}" var="_eqp">
<h:outputText value="#{_eqp}"></h:outputText>
<br/>
</c:forEach>
</h:dataTable>
</code></pre>
<p>I get the following exception when trying to run this JSP code.</p>
<pre> 15:57:59,438 ERROR [ExceptionFilter] exception root cause
javax.servlet.ServletException: javax.servlet.jsp.JspTagException:
Don't know how to iterate over supplied "items" in &lt;forEach&gt;</pre>
<p>Here's a print out of my environment</p>
<pre>
Server: JBossWeb/2.0.1.GA
Servlet Specification: 2.5
JSP version: 2.1
JSTL version: 1.2
Java Version: 1.5.0_14
</pre>
<p>Note: The following does work using a JSF tag. It prints out the list of equipment for each sport specified in the list of sportIds. </p>
<pre><code><h:dataTable value="#{bean.sportIds}" var="_sportId" >
<h:outputText value="#{bean.sportMap[_sportId].equipmentList}">
</h:outputText>
</h:dataTable>
</code></pre>
<p>I would like to use the c:forEach tag. Does anyone know if this is possible? If not, anyone have suggestions? In the end I want a stacked list instead of the comma seperated list provided by equipmentList.toString(); (Also, don't want to override toString()).</p>

<p>I need a quick easy way to get a string from a file in standard C++. I can write my own, but just want to know if there is already a standard way, in C++.</p>
<p>Equivalent of this if you know Cocoa:</p>

<p>From my understanding of the CSS spec, a table above or below a paragraph should collapse vertical margins with it. However, that's not happening here:</p>
<p><div class="snippet" data-lang="js" data-hide="true" data-console="true" data-babel="false">
<div class="snippet-code snippet-currently-hidden">
<pre class="snippet-code-css lang-css prettyprint-override"><code>table {
margin: 100px;
border: solid red 2px;
}
p {
margin: 100px
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code><table>
<tr>
<td>
This is a one-celled table with 100px margin all around.
</td>
</tr>
</table>
<p>This is a paragraph with 100px margin all around.</p></code></pre>
</div>
</div>
</p>
<p>I thought there would be 100px between the two elements, but there are 200px -- the margins aren't collapsing. </p>
<p>Why not?</p>
<p><strong>Edit:</strong> It appears to be the table's fault: if I duplicate the table and duplicate the paragraph, the two paragraphs will collapse margins. The two tables won't. And, as noted above, a table won't collapse margins with a paragraph. Is this compliant behaviour?</p>
<p><div class="snippet" data-lang="js" data-hide="true" data-console="true" data-babel="false">
<div class="snippet-code snippet-currently-hidden">
<pre class="snippet-code-css lang-css prettyprint-override"><code>table {
margin: 100px;

<p>Is it possible to make it appear to a system that a key was pressed, for example I need to make <kbd>A</kbd> key be pressed thousands of times, and it is much to time consuming to do it manually, I would like to write something to do it for me, and the only thing I know well enough is Python.</p>
<p>A better way to put it, I need to emulate a key press, I.E. not capture a key press.</p>
<p>More Info (as requested):
I am running windows XP and need to send the keys to another application.</p>

<p>I'm starting with Python coming from java. </p>
<p>I was wondering if there exists something similar to JavaDoc API where I can find the class, its methods and and example of how to use it.</p>
<p>I've found very helpul to use <em>help( thing )</em> from the Python ( command line ) </p>
<p>I have found this also:</p>
<p><a href="http://docs.python.org/2/" rel="nofollow noreferrer">http://docs.python.org/2/</a></p>
<p><a href="https://docs.python.org/2/py-modindex.html" rel="nofollow noreferrer">https://docs.python.org/2/py-modindex.html</a></p>
<p>But it seems to help when you already have the class name you are looking for. In JavaDoc API I have all the classes so if I need something I scroll down to a class that "sounds like" what I need. Or some times I just browse all the classes to see what they do, and when I need a feature my brain recalls me <em>We saw something similar in the javadoc remember!?</em> </p>
<p>But I don't seem to find the similar in Python ( yet ) and that why I'm posting this questin. </p>
<p>BTW I know that I would eventually will read this:</p>
<p><a href="https://docs.python.org/2/library/" rel="nofollow noreferrer">https://docs.python.org/2/library/</a></p>
<p>But, well, I think it is not today.</p>

<p>I have a C++ tool that walks the call stack at one point. In the code, it first gets a copy of the live CPU registers (via RtlCaptureContext()), then uses a few "<code>#ifdef ...</code>" blocks to save the CPU-specific register names into <code>stackframe.AddrPC.Offset</code>, ...<code>AddrStack</code>..., and ...<code>AddrFrame</code>...; also, for each of the 3 <code>Addr</code>... members above, it sets <code>stackframe.Addr</code>...<code>.Mode = AddrModeFlat</code>. (This was borrowed from some example code I came across a while back.)</p>
<p>With an x86 binary, this works great. With an x64 binary, though, StackWalk64() passes back bogus addresses. <i>(The first time the API is called, the only blatantly bogus address value appears in <code>AddrReturn</code> ( == <code>0xFFFFFFFF'FFFFFFFE</code> -- aka StackWalk64()'s 3rd arg, the pseudo-handle returned by GetCurrentThread()). If the API is called a second time, however, all <code>Addr</code>... variables receive bogus addresses.)</i> This happens regardless of how <code>AddrFrame</code> is set:</p>
<ul>
<li>using either of the recommended x64 "base/frame pointer" CPU registers: <code>rbp</code> (= <code>0xf</code>), or <code>rdi</code> (= <code>0x0</code>)</li>
<li>using <code>rsp</code> <i>(didn't expect it to work, but tried it anyway)</i></li>
<li>setting <code>AddrPC</code> and <code>AddrStack</code> normally, but leaving <code>AddrFrame</code> zeroed out <i>(seen in other example code)</i></li>
<li>zeroing out all <code>Addr</code>... values, to let StackWalk64() fill them in from the passed-in CPU-register context <i>(seen in other example code)</i></li>
</ul>
<p>FWIW, the physical stack buffer's contents are also different on x64 vs. x86 (after accounting for different pointer widths & stack buffer locations, of course). Regardless of the reason, StackWalk64() should still be able to walk the call stack correctly -- heck, the debugger is still able to walk the call stack, and it appears to use StackWalk64() itself behind the scenes. The oddity there is that the (correct) call stack reported by the debugger contains base-address & return-address pointer values whose constituent bytes don't actually exist in the stack buffer (below or above the current stack pointer).</p>
<p><i>(FWIW #2: Given the stack-buffer strangeness above, I did try disabling ASLR (<code>/dynamicbase:no</code>) to see if it made a difference, but the binary still exhibited the same behavior.)</i></p>
<p>So. Any ideas why this would work fine on x86, but have problems on x64? Any suggestions on how to fix it?</p>

<p>How can I drop sql server agent jobs, if (and only if) it exists?</p>
<p>This is a well functioning script for <em>stored procedures</em>. How can I do the same to sql server agent jobs?</p>
<pre><code>if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[storedproc]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)
drop procedure [dbo].[storedproc]
GO
CREATE PROCEDURE [dbo].[storedproc] ...

<p>Right now I have a log parser reading through 515mb of plain-text files (a file for each day over the past 4 years). My code currently stands as this: <a href="http://gist.github.com/12978" rel="nofollow noreferrer">http://gist.github.com/12978</a>. I've used psyco (as seen in the code) and I'm also compiling it and using the compiled version. It's doing about 100 lines every 0.3 seconds. The machine is a standard 15" MacBook Pro (2.4ghz C2D, 2GB RAM)</p>
<p>Is it possible for this to go faster or is that a limitation on the language/database?</p>

<p>I'm using this code to let the user enter in names while the program stores them in an array until they enter an empty string (they must press enter after each name):</p>
<pre><code>people = []
info = 'a' # must fill variable with something, otherwise loop won't execute
while not info.empty?
info = gets.chomp
people += [Person.new(info)] if not info.empty?
end
</code></pre>
<p>This code would look much nicer in a do ... while loop:</p>
<pre><code>people = []
do
info = gets.chomp
people += [Person.new(info)] if not info.empty?
while not info.empty?
</code></pre>
<p>In this code I don't have to assign info to some random string.</p>
<p>Unfortunately this type of loop doesn't seem to exist in Ruby. Can anybody suggest a better way of doing this?</p>

<p>After reading this answer:
<a href="https://stackoverflow.com/questions/136474/best-way-to-pick-a-random-subset-from-a-collection#136513">best way to pick a random subset from a collection?</a></p>
<p>It got me wondering, how does one pick a random seed in Java?</p>
<p>And don't say use System.currentTimeMillis() or System.nanoTime(). Read the article to see why not.</p>
<p>That's a hard question, but let me make it harder. Let's say you need to generate a random seed without connecting to the internet, without using user input (IE, there's no gui), and it has to be cross platform (therefore no JNI to access hardware).</p>
<p>Is there some JVM variables we can monitor as a source of our randomness?</p>
<p>Can this be done? Or is it impossible?</p>

<p>A few years ago I developed a web app for which we wanted to make sure the users weren't sharing credentials.</p>
<p>One of the things we decided to to, was only allow the user to be logged in from one computer at a time. The way I did this, was to have a little iframe ping the server every N seconds; as long as the server had a heartbeat for a particular user (from a particular IP), that user was not allowed to log in from any other IP.</p>
<p>The solution, although approved by my manger, always seemed hacky to me. Also, it seems like it would be easy to circumvent.</p>
<p>Is there a good way to make sure a web app user only logs in once? To be honest, I never understood why management even wanted this feature. Does it make sense to enforce this on distributed apps?</p>

<p>So why exactly is it that it's always recommended to use const as often as possible? It seems to me that using const can be more of a pain than a help in C++. But then again, I'm coming at this from the python perspective: if you don't want something to be changed, don't change it. So with that said, here are a few questions:</p>
<ol>
<li><p>It seems like every time I mark something as const, I get an error and have to change some other function somewhere to be const too. Then this causes me to have to change <em>another</em> function somewhere else. Is this something that just gets easier with experience?</p></li>
<li><p>Are the benefits of using const <em>really</em> enough to compensate for the trouble? If you don't intend on changing an object, why not just not write code that doesn't change it?</p></li>
</ol>
<p>I should note that at this point in time, I'm most focused on the benefits of using const for correctness and maintainability purposes, although it is also nice to have an idea of the performance implications.</p>

<p>Is it possible to have a <code><div></code> simultaneously (1) not take up all available width and (2) collapse margins with its neighbors?</p>
<p>I learned recently that setting a <code>div</code> to <code>display:table</code> will stop it from expanding to take up the whole width of the parent container -- but now I realize that this introduces a new problem: it stops collapsing margins with its neighbors.</p>
<p>In the example below, the red div fails to collapse, and the blue div is too wide.</p>
<pre><code><p style="margin:100px">This is a paragraph with 100px margin all around.</p>
<div style="margin: 100px; border: solid red 2px; display: table;">
This is a div with 100px margin all around and display:table.
<br/>
The problem is that it doesn't collapse margins with its neighbors.
</div>
<p style="margin:100px">This is a paragraph with 100px margin all around.</p>
<div style="margin: 100px; border: solid blue 2px; display: block;">
This is a div with 100px margin all around and display:block.
<br/>
The problem is that it expands to take up all available width.
</div>
<p style="margin:100px">This is a paragraph with 100px margin all around.</p>
</code></pre>
<p>Is there a way to meet both criteria simultaneously?</p>

<p>In your opinion, is it ever valid to use the @ operator to suppress an error/warning in PHP whereas you may be handling the error?</p>
<p>If so, in what circumstances would you use this?</p>
<p>Code examples are welcome.</p>
<p>Edit: Note to repliers. I'm not looking to turn error reporting off, but, for example, common practice is to use</p>
<pre><code>@fopen($file);
</code></pre>
<p>and then check afterwards... but you can get rid of the @ by doing</p>
<pre><code>if (file_exists($file))
{
fopen($file);
}
else
{
die('File not found');
}
</code></pre>
<p>or similar. </p>
<p>I guess the question is - is there anywhere that @ HAS to be used to supress an error, that CANNOT be handled in any other manner?</p>

<p>Is there a way to respond to the back button being hit (or backspace being pressed) in javascript when only the location hash changes? That is to say when the browser is not communicating with the server or reloading the page.</p>

<p>What's the difference between using a define statement and an enum statement in C/C++ (and is there any difference when using them with either C or C++)?</p>
<p>For example, when should one use</p>
<pre><code>enum {BUFFER = 1234};
</code></pre>
<p>over</p>
<pre><code>#define BUFFER 1234
</code></pre>

<p>I used to be able to launch a locally installed helper application by registering a given mime-type in the Windows registry. This enabled me to allow users to be able to click once on a link to the current install of our internal browser application. This worked fine in Internet Explorer 5 (most of the time) and Firefox but now does not work in Internet Explorer 7.</p>
<p>The filename passed to my shell/open/command is not the full physical path to the downloaded install package. The path parameter I am handed by IE is</p>
<pre><code>"C:\Document and Settings\chq-tomc\Local Settings\Temporary Internet Files\
EIPortal_DEV_2_0_5_4[1].expd"
</code></pre>
<p>This unfortunately does not resolve to the physical file when calling <code>FileExists()</code> or when attempting to create a <code>TFileStream</code> object.</p>
<p>The physical path is missing the Internet Explorer hidden caching sub-directory for Temporary Internet Files of <code>"Content.IE5\ALBKHO3Q"</code> whose absolute path would be expressed as</p>
<pre><code>"C:\Document and Settings\chq-tomc\Local Settings\Temporary Internet Files\
Content.IE5\ALBKHO3Q\EIPortal_DEV_2_0_5_4[1].expd"
</code></pre>
<p>Yes, the sub-directories are randomly generated by IE and that should not be a concern so long as IE passes the full path to my helper application, which it unfortunately is not doing.</p>
<p>Installation of the mime helper application is not a concern. It is installed/updated by a global login script for all 10,000+ users worldwide. The mime helper is only invoked when the user clicks on an internal web page with a link to an installation of our Desktop browser application. That install is served back with a mime-type of <code>"application/x-expeditors"</code>. The registration of the <code>".expd"</code> / <code>"application/x-expeditors"</code> mime-type looks like this.</p>
<pre><code>[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.expd]
@="ExpeditorsInstaller"
"Content Type"="application/x-expeditors"
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\ExpeditorsInstaller]
"EditFlags"=hex:00,00,01,00
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\ExpeditorsInstaller\shell]
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\ExpeditorsInstaller\shell\open]
@=""
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\ExpeditorsInstaller\shell\open\command]
@="\"C:\\projects\\desktop2\\WebInstaller\\WebInstaller.exe\" \"%1\""
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\MIME\Database\Content Type\application/x-expeditors]
"Extension"=".expd"
</code></pre>
<p>I had considered enumerating all of a user's IE cache entries but I would be concerned with how long it may take to examine them all or that I may end up finding an older cache entry before the current entry I am looking for. However, the bracketed filename suffix <code>"[n]"</code> may be the unique key.</p>
<p>I have tried wininet method <code>GetUrlCacheEntryInfo</code> but that requires the URL, not the virtual path handed over by IE.</p>
<p>My hope is that there is a Shell function that given a virtual path will hand back the physical path.</p>

<p>I'm using the jQuery Form plugin to upload an image. I've assigned a fade animation to happen the <code>beforeSubmit</code> callback, but as I'm running locally, it doesn't have time to finish before the <code>success</code> function is called. </p>
<p>I am using a callback function in my <code>fade();</code> call to make sure that one fade completes, before the next one begins, but that does not seem to guarantee that the function that's calling it is finished.</p>
<p>Am I doing something wrong? Shouldn't <code>beforeSubmit</code> complete before the ajax call is submitted?</p>
<p>Here's are the two callbacks:</p>
<p>beforeSubmit:</p>
<pre><code>function prepImageArea() {
if (userImage) {
userImage.fadeOut(1500, function() {
ajaxSpinner.fadeIn(1500);
});
}
}
</code></pre>
<p>success:</p>
<pre><code>function imageUploaded(data) {
var data = evalJson(data);
userImage.attr('src', data.large_thumb);
ajaxSpinner.fadeOut(1500, function() {
userImage.fadeIn(1500);
});
}
</code></pre>

<p>Is there a way to tell if an event handler has been added to an object? I'm serializing a list of objects into/out of session state so we can use SQL based session state... When an object in the list has a property changed it needs to be flagged, which the event handler took care of properly before. However now when the objects are deserialized it isn't getting the event handler.</p>
<p>In an fit of mild annoyance, I just added the event handler to the Get property that accesses the object. It's getting called now which is great, except that it's getting called like 5 times so I think the handler just keeps getting added every time the object is accessed.</p>
<p>It's really safe enough to just ignore, but I'd rather make it that much cleaner by checking to see if the handler has already been added so I only do so once.</p>
<p>Is that possible?</p>
<p>EDIT: I don't necessarily have full control of what event handlers are added, so just checking for null isn't good enough. </p>

<p>Is there any way to redefine a class or some of its methods without using typical inheritance? For example:</p>
<pre><code>class third_party_library {
function buggy_function() {
return 'bad result';
}
function other_functions(){
return 'blah';
}
}
</code></pre>
<p>What can I do to replace <code>buggy_function()</code>? Obviously this is what I would like to do</p>
<pre><code>class third_party_library redefines third_party_library{
function buggy_function() {
return 'good result';
}
function other_functions(){
return 'blah';
}
}
</code></pre>
<p>This is my exact dilemma: I updated a third party library that breaks my code. I don't want to modify the library directly, as future updates could break the code again. I'm looking for a seamless way to replace the class method.</p>
<p>I've found this <a href="http://pecl.php.net/package/classkit" rel="noreferrer">library</a> that says it can do it, but I'm wary as it's 4 years old.</p>
<p>EDIT:</p>
<p>I should have clarified that I cannot rename the class from <code>third_party_library</code> to <code>magical_third_party_library</code> or anything else because of framework limitations.</p>
<p>For my purposes, would it be possible to just add a function to the class? I think you can do this in C# with something called a "partial class."</p>

<p>I have a lot of nice MATLAB code that runs too slowly and would be a pain to write over in C. The MATLAB compiler for C does not seem to help much, if at all. Should it be speeding execution up more? Am I screwed?</p>

<p>What is the best way to take a given PHP object and serialize it as XML? I am looking at simple_xml and I have used it to parse XML into objects, but it isn't clear to me how it works the other way around.</p>

<p>I have a problem which requires me to parse several log files from a remote machine.
There are a few complications:
1) The file may be in use
2) The files can be quite large (100mb+)
3) Each entry may be multi-line</p>
<p>To solve the in-use issue, I need to copy it first. I'm currently copying it directly from the remote machine to the local machine, and parsing it there. That leads to issue 2. Since the files are quite large copying it locally can take quite a while.</p>
<p>To enhance parsing time, I'd like to make the parser multi-threaded, but that makes dealing with multi-lined entries a bit trickier. </p>
<p>The two main issues are:
1) How do i speed up the file transfer (Compression?, Is transferring locally even neccessary?, Can I read an in use file some other way?)
2) How do i deal with multi-line entries when splitting up the lines among threads?</p>
<p>UPDATE: The reason I didnt do the obvious parse on the server reason is that I want to have as little cpu impact as possible. I don't want to affect the performance of the system im testing.</p>

<p>How can I validate that my ASPNET AJAX installation is correct.</p>
<p>I have Visual Studio 2008 and had never previously installed any AJAX version.</p>
<p>My UpdatePanel is nto working within IIS6, although it works ok within Visual Studio's web server. The behaviour I get is as if the UpdatePanel doesnt exist at all - i.e. it reverts back to 'normal' ASPX type behavior.</p>
<p>I tried installing AJAX from <a href="http://www.microsoft.com/downloads/details.aspx?FamilyID=ca9d90fa-e8c9-42e3-aa19-08e2c027f5d6&displaylang=en" rel="nofollow noreferrer">MSDN</a> followed by an IISRESET yet still it is still not working properly.</p>
<p>What can I check to diagnose the problem?</p>
<p><strong>Update:</strong> When running within Visual Studio (Cassini) I get the following 3 requests shown in Fiddler:</p>
<pre><code>http://localhost:1105/RRStatistics/WebResource.axd?d=k5J0oI4tNNc1xbK-2DAgZg2&t=633564733834698722
http://localhost:1105/RRStatistics/ScriptResource.axd?d=N8BdmNpXVve13PiOuRcss0GMKpoTBFsi7UcScm-WmXE9jw5qOijeLDcIyiOsSQZ4k3shu0R2ly5WhH2vI_IbNVcTbxej1dkbdYFXrN6c7Qw1&t=ffffffff867086f6
http://localhost:1105/RRStatistics/ScriptResource.axd?d=N8BdmNpXVve13PiOuRcss0GMKpoTBFsi7UcScm-WmXE9jw5qOijeLDcIyiOsSQZ4AsqNeJVXGSf6sCcCp1QK0jdKTlbRqIN1LFVP8w6R0lJ_vbk-CfopYINgjYsHpWfP0&t=ffffffff867086f6
</code></pre>
<p>but when I run within IIS i only get this single request :</p>
<pre><code>http://www.example.com/RRStatistics/ScriptResource.axd?d=f_uL3BYT2usKhP7VtSYNUxxYRLVrX5rhnXUonvvzSEIc1qA5dLOlcdNr9xlkSQcnZKyBHj1nI523o9DjxNr45hRpHF7xxC5WlhImxu9TALw1&t=ffffffff867086f6
</code></pre>
<p>Now the second request in Cassini contains a javascript file with 'partial rendering' as one of the first comments. I'm sure this is the source of the problem, but I cannot figure out why in IIS i dont get the other requests.</p>

<p>I just found myself creating a class called "InstructionBuilderFactoryMapFactory". That's 4 "pattern suffixes" on one class. It immediately reminded me of this:</p>
<p><a href="http://www.jroller.com/landers/entry/the_design_pattern_facade_pattern" rel="nofollow noreferrer">http://www.jroller.com/landers/entry/the_design_pattern_facade_pattern</a></p>
<p>Is this a design smell? Should I impose a limit on this number? </p>
<p>I know some programmers have similar rules for other things (e.g. no more than N levels of pointer indirection in C.)</p>
<p>All the classes seem necessary to me. I have a (fixed) map from strings to factories - something I do all the time. The list is getting long and I want to move it out of the constructor of the class that uses the builders (that are created by the factories that are obtained from the map...) And as usual I'm avoiding Singletons.</p>

<p>I'm trying to use boost::signal to implement a callback mechanism, and I'm getting a memory access assert in the boost::signal code on even the most trivial usage of the library. I have simplified it down to this code:</p>
<pre><code>#include <boost/signal.hpp>
typedef boost::signal<void (void)> Event;
int main(int argc, char* argv[])
{
Event e;
return 0;
}
</code></pre>
<p>Thanks!</p>
<p>Edit: This was Boost 1.36.0 compiled with Visual Studio 2008 w/ SP1. Boost::filesystem, like boost::signal also has a library that must be linked in, and it seems to work fine. All the other boost libraries I use are headers-only, I believe.</p>

<p>At my new workplace, they represent a lot of dates as "days since epoch" (which I will hereafter call DSE). I'm running into issues in JavaScript converting from DSE to seconds since epoch (UNIX timestamps). Here's my function to do the conversion:</p>
<pre><code>function daysToTimestamp(days) {
return Math.round(+days * 86400);
}
</code></pre>
<p>By way of example, when I pass in 13878 (expecting that this represents January 1, 2008), I get back 1199059200, not 1199098800 as I expect. Why?</p>

<p>What's the best tool for viewing and editing a merge in Git? I'd like to get a 3-way merge view, with "mine", "theirs" and "ancestor" in separate panels, and a fourth "output" panel.</p>
<p>Also, instructions for invoking said tool would be great. (I still haven't figure out how to start kdiff3 in such a way that it doesn't give me an error.)</p>
<p>My OS is Ubuntu.</p>

<p>Whats the best way to round in VBA Access?</p>
<p>My current method utilizes the Excel method</p>
<pre><code>Excel.WorksheetFunction.Round(...

<p>But I am looking for a means that does not rely on Excel.</p>

<p>For example</p>
<pre><code>int f(int a) {
...
return a > 10;
}
</code></pre>
<p>is that considered acceptable (not legal, I mean is it ``good code''), or should it always be in a conditional, like this</p>
<pre><code>int f(int a) {
...
if (a > 10)
return 1;
else
return 0;
}
</code></pre>

<p>What's the command line argument to do this? Or is there a place to find the explanation of RegEdit's switches?</p>

<p>If you want a cryptographically strong random numbers in Java, you use <code>SecureRandom</code>. Unfortunately, <code>SecureRandom</code> can be very slow. If it uses <code>/dev/random</code> on Linux, it can block waiting for sufficient entropy to build up. How do you avoid the performance penalty?</p>
<p>Has anyone used <a href="https://uncommons-maths.dev.java.net/" rel="noreferrer">Uncommon Maths</a> as a solution to this problem?</p>
<p>Can anybody confirm that this performance problem has been solved in JDK 6?</p>

<p>I am looking for the way to mount NTFS hard disk on FreeBSD 6.2 in read/write mode.</p>
<p>searching google, I found that NTFS-3G can be a help.</p>
<p>Using NTFS-3G, there is no problem when I try to mount/unmount NTFS manually:</p>
<p>mount: ntfs-3g /dev/ad1s1 /home/admin/data -o uid=1002,</p>
<p>or</p>
<p>umount: umount /home/admin/data</p>
<p>But I have a problem when try to mount ntfs hard disk automatically at boot time.</p>
<p>I have tried: </p>
<ul>
<li>adding fstab: /dev/ad1s1 /home/admin/data ntfs-3g uid=1002 0 0</li>
<li>make a script, that automatically mount ntfs partition at start up, on /usr/local/etc/rc.d/ directory.</li>
</ul>
<p>But it is still failed.
The script works well when it is executed manually.</p>
<p>Does anyone know an alternative method/ solution to have read/write access NTFS on FreeBSD 6.2?</p>
<p>Thanks.</p>

<p>I've searched around for a while today, but I haven't been able to come up with an AutoComplete TextBox code sample for Silverlight 2 Beta 2. The most promising reference was found on <a href="http://www.nikhilk.net/Silverlight-AutoComplete.aspx/" rel="nofollow noreferrer">nikhilk.net</a> but the online demo doesn't currently render and after downloading a getting the code to compile with Beta 2, I couldn't get the Silverlight plugin it to render either. I think it is fair to say it is a compatibility issue, but I'm not sure. Does anyone have any alternate sample code or implementation suggestions?</p>

<p>I bumped into a strange situation with MSBuild just now. There's a solution which has three projects: LibX, LibY and Exe. Exe references LibX. LibX in its turn references LibY, has some content files, and also references to a third-party library (several pre-built assemblies installed in both GAC and local lib folder). The third-party library is marked as "Copy Local" ("private") and appears in the output of the LibX project, as the LibY's output and LibX's content files do. Now, Exe project's output has LibX project output, content files of the LibX project, LibY project output (coming from LibX), but NO third-party library's assemblies.</p>
<p>Now I worked this around by referencing the third-party library directly in Exe project, but I don't feel this is a "right" solution.</p>
<p>Anyone had this problem before?</p>

<p>Here's a common code pattern I have to work with:</p>
<pre><code>class foo {
public:
void InitMap();
void InvokeMethodsInMap();
static void abcMethod();
static void defMethod();
private:
typedef std::map<const char*, pMethod> TMyMap;
TMyMap m_MyMap;
}
void
foo::InitMap()
{
m_MyMap["abc"] = &foo::abcMethod;
m_MyMap["def"] = &foo::defMethod;
}
void
foo::InvokeMethodsInMap()
{
for (TMyMap::const_iterator it = m_MyMap.begin();
it != m_MyMap.end(); it++)
{
(*it->second)(it->first);
}
}
</code></pre>
<p>However, I have found that the <em>order</em> that the map is processed in (within the for loop) can differ based upon whether the build configuration is Release or Debug. It seems that the compiler optimisation that occurs in Release builds affects this order.</p>
<p>I thought that by using <code>begin()</code> in the loop above, and incrementing the iterator after each method call, it would process the map in order of initialisation. However, I also remember reading that a map is implemented as a hash table, and order cannot be guaranteed.</p>
<p>This is particularly annoying, as most of the unit tests are run on a Debug build, and often strange order dependency bugs aren't found until the external QA team start testing (because they use a Release build).</p>
<p>Can anyone explain this strange behaviour?</p>

<p>I've been doing some mocking with RhinoMocks and it requires that mocked methods be made virtual. This is fine except we have a custom framework which contains the methods that I want to mock which are currently not marked as virtual.</p>
<p>I can't forsee any problem with making these methods virtual but I was wondering what are some potential dangers of making methods virtual that I should look out for?</p>

<p>What is the best way to read an HTTP response from GetResponseStream ?</p>
<p>Currently I'm using the following approach.</p>
<pre><code>Using SReader As StreamReader = New StreamReader(HttpRes.GetResponseStream)
SourceCode = SReader.ReadToEnd()
End Using
</code></pre>
<p>I'm not quite sure if this is the most efficient way to read an http response.</p>
<p>I need the output as string, I've seen an <a href="http://www.informit.com/guides/content.aspx?g=dotnet&seqNum=583" rel="noreferrer">article</a> with a different approach but I'm not quite if it's a good one. And in my tests that code had some encoding issues with in different websites.</p>
<p>How do you read web responses?</p>

<p>I've been parsing through some log files and I've found that some of the lines are too long to display on one line so Terminal.app kindly wraps them onto the next line. However, I've been looking for a way to truncate a line after a certain number of characters so that Terminal doesn't wrap, making it much easier to spot patterns.</p>
<p>I wrote a small Perl script to do this:</p>
<pre><code>#!/usr/bin/perl
die("need max length\n") unless $#ARGV == 0;
while (<STDIN>)
{
$_ = substr($_, 0, $ARGV[0]);
chomp($_);
print "$_\n";
}
</code></pre>
<p>But I have a feeling that this functionality is probably built into some other tools (sed?) That I just don't know enough about to use for this task.</p>
<p>So my question sort of a reverse question: how do I truncate a line of stdin Without writing a program to do it?</p>
