73,629 | <p>I have a string that is like below.</p>
<pre><code>,liger, unicorn, snipe
</code></pre>
<p>in other languages I'm familiar with I can just do a string.trim(",") but how can I do that in c#?</p>
<p>Thanks.</p>
<hr>
<p><em>There's been a lot of back and forth about the StartTrim function. As several have pointed out, the StartTrim doesn't affect the primary variable. However, given the construction of the data vs the question, I'm torn as to which answer to accept. True the question only wants the first character trimmed off not the last (if anny), however, there would never be a "," at the end of the data. So, with that said, I'm going to accept the first answer that that said to use StartTrim assigned to a new variable.</em></p>

73,674 | <p>I talked to a friend of mine and he told me that it's possible to create an image in an image editor (gimp/photoshop) and then use it as a button . He said that's the way applications that have great GUIs do it. </p>
<p>He also said that there is a file describing which parts of the image make up the button.</p>
<p>Is this possible , or is he "crazy"? :)</p>

73,748 | <p>I have a dropdownlist with the autopostback set to true. I want the
user to confirm if they really want to change the value,
which on post back fires a server side event (selectedindexchanged).</p>
<p>I have tried adding an onchange attribute "return confirm('Please click OK to change. Otherwise click CANCEL?';") but it will not postback regardless of the confirm
result and the value in the list does not revert back if cancel
selected. </p>
<p>When I remove the onchange attribute from the DropdownList tag, the page does postback. It does not when the onchange attribute is added. Do I still need to wire the event handler (I'm on C# .Net 2.0 ).</p>
<p>Any leads will be helpful.</p>

73,781 | <p>If I want to send mail not via SMTP, but rather via sendmail, is there a library for python that encapsulates this process?</p>
<p>Better yet, is there a good library that abstracts the whole 'sendmail -versus- smtp' choice?</p>
<p>I'll be running this script on a bunch of unix hosts, only some of which are listening on localhost:25; a few of these are part of embedded systems and can't be set up to accept SMTP.</p>
<p>As part of Good Practice, I'd really like to have the library take care of header injection vulnerabilities itself -- so just dumping a string to <code>popen('/usr/bin/sendmail', 'w')</code> is a little closer to the metal than I'd like.</p>
<p>If the answer is 'go write a library,' so be it ;-)</p>

73,825 | <p>This is about when a .NET remoting exception is thrown. If you take a look at MSDN, it will mention that a remoting exception is thrown when something goes wrong with remoting. If my server is not running, I get a socket exception which is fine.</p>
<p>What I am trying to figure out is: does getting a remoting exception indicate for sure that my server is up and running? If yes, that would solve the problem. If not: Is there a way to figure out if the remoting exception originated on the client side or the server side?</p>
<h3>Update:</h3>
<p>The problem I am trying to solve is that the server is down initially and then client sends some message to the server. Now I get a socket exception saying "No connection could be made..." which is fine.</p>
<p>There is a thread that is sending messages to the server at regular intervals to see if the server is available. Now, the server comes up, and at that point, you could get the response which is fine or you could get some exception and most probably it will be a remote exception. So, what I am trying to ask is that: in case I don't get a message and I get a remote exception is there a chance that the server is up and running and I am still getting this exception?</p>
<p>All I am doing is just calling a method on the remote object that does nothing and returns. If there is no exception then I am good. Now, if there is a remoting exception and if I knew the remoting exception occurred on the server then I know in spite getting the exception, I am connected to the server.</p>

73,947 | <p>I'm talking about an action game with no upper score limit and no way to verify the score on the server by replaying moves etc. </p>
<p>What I really need is the strongest encryption possible in Flash/PHP, and a way to prevent people calling the PHP page other than through my Flash file. I have tried some simple methods in the past of making multiple calls for a single score and completing a checksum / fibonacci sequence etc, and also obfuscating the SWF with Amayeta SWF Encrypt, but they were all hacked eventually.</p>
<p>Thanks to StackOverflow responses I have now found some more info from Adobe - <a href="http://www.adobe.com/devnet/flashplayer/articles/secure_swf_apps_12.html" rel="noreferrer">http://www.adobe.com/devnet/flashplayer/articles/secure_swf_apps_12.html</a> and <a href="https://github.com/mikechambers/as3corelib" rel="noreferrer">https://github.com/mikechambers/as3corelib</a> - which I think I can use for the encryption. Not sure this will get me around CheatEngine though.</p>
<p>I need to know the best solutions for both AS2 and AS3, if they are different.</p>
<p>The main problems seem to be things like TamperData and LiveHTTP headers, but I understand there are more advanced hacking tools as well - like CheatEngine (thanks Mark Webster)</p>

73,960 | <p>In IE, the dropdown-list takes the same width as the dropbox (I hope I am making sense) whereas in Firefox the dropdown-list's width varies according to the content. </p>
<p>This basically means that I have to make sure that the dropbox is wide enough to display the longest selection possible. This makes my page look very ugly :(</p>
<p>Is there any workaround for this problem?
How can I use CSS to set different widths for dropbox and the dropdownlist?</p>

73,971 | <p>In JavaScript, what is the best way to determine if a date provided falls within a valid range?</p>
<p>An example of this might be checking to see if the user input <code>requestedDate</code> is part of the next valid work week. Note that this is not just checking to see if one date is larger than another as a valid date would be equal to or greater than the lower end of the range while less than or equal to the upper end of the range.</p>

74,092 | <p>I have a function in Python which is iterating over the attributes returned from <code>dir(obj)</code>, and I want to check to see if any of the objects contained within is a function, method, built-in function, etc. Normally you could use <code>callable()</code> for this, but I don't want to include classes. The best I've come up with so far is:</p>
<pre><code>isinstance(obj, (types.BuiltinFunctionType, types.FunctionType, types.MethodType))
</code></pre>
<p>Is there a more future-proof way to do this check?</p>
<p><strong>Edit:</strong> I misspoke before when I said: "Normally you could use <code>callable()</code> for this, but I don't want to disqualify classes." I actually <em>do</em> want to disqualify classes. I want to match <em>only</em> functions, not classes.</p>

I tried <a href="http://foafscape.berlios.de/" rel="nofollow noreferrer">http://foafscape.berlios.de/</a> but for 300+ Nodes it is really slow and does a bad job on auto formatting.</p>
<p>Any hints for good graph visualization tools? It's ok if they do not support foaf directly, but they should be able to use images for graph nodes and be able to display large graphs. Linux support would be nice.</p>
<p>Oh, and I'm searching for an interactive tool where I can move nodes by hand.</p>
<p><strong>Update:</strong> Thanks for your input. I know graphviz and for static images it is really great. But for large datasets I need to be able to select nodes and highlight all neighbours. </p>

74,188 | <p>I've created a ListBox to display items in groups, where the groups are wrapped right to left when they can no longer fit within the height of the ListBox's panel. So, the groups would appear similar to this in the listbox, where each group's height is arbitrary (group 1, for instance, is twice as tall as group 2):</p>
<pre><code>[ 1 ][ 3 ][ 5 ]
[ ][ 4 ][ 6 ]
[ 2 ][ ]
</code></pre>
<p>The following XAML works correctly in that it performs the wrapping, and allows the horizontal scroll bar to appear when the items run off the right side of the ListBox.</p>
<pre><code><ListBox>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Vertical"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.GroupStyle>
<ItemsPanelTemplate>
<WrapPanel Orientation="Vertical"
Height="{Binding Path=ActualHeight,
RelativeSource={RelativeSource
FindAncestor,
AncestorLevel=1,
AncestorType={x:Type ScrollContentPresenter}}}"/>
</ItemsPanelTemplate>
</ListBox.GroupStyle>
</ListBox>
</code></pre>
<p>The problem occurs when a group of items is longer than the height of the WrapPanel. Instead of allowing the vertical scroll bar to appear to view the cutoff item group, the items in that group are simply clipped. I'm assuming that this is a side effect of the Height binding in the WrapPanel - the scrollbar thinks it does not have to enabled.</p>
<p>Is there any way to enable the scrollbar, or another way around this issue that I'm not seeing?</p>

74,315 | <p>I'm doing a website for a family member's wedding. A feature they requested was a photo section where all the guests could go after the wedding and upload their snaps. I said this was a stellar idea and I went off to build it.</p>
<p>Well there's just the one problem: logistics. Upload speeds are slow and photos from modern cameras are huge (2-5+Megs). </p>
<p>I will only need ~800px wide images and some of them might require rotating so ideally I'm looking about using a client-side editor to do three things:</p>
<ol>
<li>Let users pick multiple files</li>
<li>Let them rotate some images so they're the right way up</li>
<li>Resize them and then upload</li>
</ol>
<p>And in my dream world, it'd be free and open source. Any ideas?</p>
<p>Just a reminder: this is something the guests have to use. Some of them will be pretty computer savvy but others will be almost completely illiterate. Installing desktop apps isn't really an option. And I assume 98% of them have Flash and Java installed.</p>
<p>Edit: I'd prefer a Flash/Java option over SilverLight, not least because it has a smaller install rate at the moment, but also because I'm on Linux and I'd like to test it =)</p>

Sometimes the <code>#include</code>s are just artifacts and everything will compile fine with them removed, and in other cases classes could be forward declared and the #include could be moved to the <code>.cpp</code> file. Are there any good tools for detecting both of these cases?</p>

74,350 | <p>I'm trying to implement some drag and drop functionality for a material system being developed at my work. Part of this system includes a 'Material Library' which acts as a repository, divided into groups, of saved materials on the user's hard drive.</p>
<p>As part of some UI polish, I was hoping to implement a 'highlight' type feature. When dragging and dropping, windows that you can legally drop a material onto will very subtly change color to improve feedback to the user that this is a valid action.</p>
<p>I am changing the bar with 'Basic Materials' (Just a CWnd with a CStatic) from having a medium gray background when unhighlighed to a blue background when hovered over. It all works well, the OnDragEnter and OnDragExit messages seem robust and set a flag indicating the highlight status. Then in OnCtrlColor I do this:</p>
<pre><code> if (!m_bHighlighted) {
pDC->FillSolidRect(0, 0, m_SizeX, kGroupHeaderHeight, kBackgroundColour);
}
else {
pDC->FillSolidRect(0, 0, m_SizeX, kGroupHeaderHeight, kHighlightedBackgroundColour);
}
</code></pre>
<p>However, as you can see in the screenshot, the painting 'glitches' below the dragged object, leaving the original gray in place. It looks really ugly and basically spoils the whole effect.</p>
<p>Is there any way I can get around this?</p>

74,358 | <p>How can I get <a href="http://search.cpan.org/perldoc?LWP" rel="noreferrer">LWP</a> to verify that the certificate of the server I'm connecting to is signed by a trusted authority and issued to the correct host? As far as I can tell, it doesn't even check that the certificate claims to be for the hostname I'm connecting to. That seems like a major security hole (especially with the recent DNS vulnerabilities).</p>
<p><strong>Update:</strong> It turns out what I really wanted was <code>HTTPS_CA_DIR</code>, because I don't have a ca-bundle.crt. But <code>HTTPS_CA_DIR=/usr/share/ca-certificates/</code> did the trick. I'm marking the answer as accepted anyway, because it was close enough.</p>
<p><strong>Update 2:</strong> It turns out that <code>HTTPS_CA_DIR</code> and <code>HTTPS_CA_FILE</code> only apply if you're using Net::SSL as the underlying SSL library. But LWP also works with IO::Socket::SSL, which will ignore those environment variables and happily talk to any server, no matter what certificate it presents. Is there a more general solution?</p>
<p><strong>Update 3:</strong> Unfortunately, the solution still isn't complete. Neither Net::SSL nor IO::Socket::SSL is checking the host name against the certificate. This means that someone can get a legitimate certificate for some domain, and then impersonate any other domain without LWP complaining.</p>
<p><strong>Update 4:</strong> <a href="http://search.cpan.org/dist/libwww-perl/" rel="noreferrer">LWP 6.00</a> finally solves the problem. See <a href="https://stackoverflow.com/questions/74358/how-can-i-get-lwp-to-validate-ssl-server-certificates#5329129">my answer</a> for details.</p>

74,372 | <p>I am involved in the process of porting a system containing several hundreds of ksh scripts from AIX, Solaris and HPUX to Linux. I have come across the following difference in the way ksh behaves on the two systems:</p>
<pre><code>#!/bin/ksh
flag=false
echo "a\nb" | while read x
do
flag=true
done
echo "flag = ${flag}"
exit 0
</code></pre>
<p>On AIX, Solaris and HPUX the output is "flag = true" on Linux the output is "flag = false".</p>
<p>My questions are:</p>
<ul>
<li>Is there an environment variable that I can set to get Linux's ksh to behave like the
other Os's'? Failing that:</li>
<li>Is there an option on Linux's ksh to get the required behavior? Failing that:</li>
<li>Is there a ksh implementation available for Linux with the desired behavior?</li>
</ul>
<p>Other notes:</p>
<ul>
<li>On AIX, Solaris and HPUX ksh is a variant of ksh88.</li>
<li>On Linux, ksh is the public domain ksh (pdksh)</li>
<li>On AIX, Solaris and HPUX dtksh and ksh93 (where I have them installed) are consistent with ksh</li>
<li>The Windows NT systems I have access to: Cygwin and MKS NT, are consistent with Linux.</li>
<li>On AIX, Solaris and Linux, bash is consistent, giving the incorrect (from my perspective) result of "flag = false".</li>
</ul>
<p>The following table summarizes the systems the problem:</p>
<pre><code>uname -s uname -r which ksh ksh version flag =
======== ======== ========= =========== ======
Linux 2.6.9-55.0.0.0.2.ELsmp /bin/ksh PD KSH v5.2.14 99/07/13.2 false
AIX 3 /bin/ksh Version M-11/16/88f true // AIX 5.3
/bin/ksh93 Version M-12/28/93e true
SunOS 5.8, 5.9 and 5.10 /bin/ksh Version M-11/16/88i true
/usr/dt/bin/dtksh Version M-12/28/93d true
HP-UX B.11.11 and B.11.23 /bin/ksh Version 11/16/88 true
/usr/dt/bin/dtksh Version M-12/28/93d true
CYGWIN_NT-5.1 1.5.25(0.156/4/2) /bin/ksh PD KSH v5.2.14 99/07/13.2 false
Windows_NT 5 .../mksnt/ksh.exe Version 8.7.0 build 1859... false // MKS
</code></pre>
<h1>Update</h1>
<p>After some advice from people in my company we decided to make the following modification to the code. This gives us the same result whether using the "real" ksh's (ksh88, ksh93) or any of the ksh clones (pdksh, MSK ksh). This also works correctly with bash.</p>
<pre><code>#!/bin/ksh
echo "a\nb" > junk
flag=false
while read x
do
flag=true
done < junk
echo "flag = ${flag}"
exit 0
</code></pre>
<p>Thanks to jj33 for the previously accepted answer.</p>

74,451 | <p>Windows file system is case insensitive. How, given a file/folder name (e.g. "somefile"), I get the <em>actual</em> name of that file/folder (e.g. it should return "SomeFile" if Explorer displays it so)?</p>
<p>Some ways I know, all of which seem quite backwards:</p>
<ol>
<li>Given the full path, search for each folder on the path (via FindFirstFile). This gives proper cased results of each folder. At the last step, search for the file itself.</li>
<li>Get filename from handle (as in <a href="http://msdn.microsoft.com/en-us/library/aa366789(VS.85).aspx" rel="noreferrer">MSDN example</a>). This requires opening a file, creating file mapping, getting it's name, parsing device names etc. Pretty convoluted. And it does not work for folders or zero-size files.</li>
</ol>
<p>Am I missing some obvious WinAPI call? The simplest ones, like GetActualPathName() or GetFullPathName() return the name using casing that was passed in (e.g. returns "program files" if that was passed in, even if it should be "Program Files").</p>
<p>I'm looking for a native solution (not .NET one).</p>

74,461 | <p>I'm currently playing with the Silverlight(Beta 2) Datagrid control. Before I wired up the SelectionChanged event, the grid would sort perfectly by clicking on the header. Now, when the grid is clicked, it will fire the SelectionChanged event when I click the header to sort. Is there any way around this?</p>
<p>In a semi-related topic, I'd like to have the SelectionChanged event fire when I click on an already selected item (so that I can have a pop-up occur to allow the user to edit the selected value). Right now, you have to click on a different value and then back to the value you wanted in order for it to pop up. Is there another way? </p>

74,514 | <p>Implementing Equals() for reference types is harder than it seems. My current canonical implementation goes like this:</p>
<pre><code>public bool Equals( MyClass obj )
{
// If both refer to the same reference they are equal.
if( ReferenceEquals( obj, this ) )
return true;
// If the other object is null they are not equal because in C# this cannot be null.
if( ReferenceEquals( obj, null ) )
return false;
// Compare data to evaluate equality
return _data.Equals( obj._data );
}
public override bool Equals( object obj )
{
// If both refer to the same reference they are equal.
if( ReferenceEquals( obj, this ) )
return true;
// If the other object is null or is of a different types the objects are not equal.
if( ReferenceEquals( obj, null ) || obj.GetType() != GetType() )
return false;
// Use type-safe equality comparison
return Equals( (MyClass)obj );
}
public override int GetHashCode()
{
// Use data's hash code as our hashcode
return _data.GetHashCode();
}
</code></pre>
<p>I think that this covers all corner (inheritance and such) cases but I may be wrong. What do you guys think?</p>

74,570 | <p>I'm maintaining <a href="http://perl-begin.org/" rel="nofollow noreferrer">the Perl Beginners' Site</a> and used a modified template from Open Source Web Designs. Now, the problem is that I still have an undesired artifact: a gray line on the left side of the main frame, to the left of the navigation menu. Here's <a href="http://www.shlomifish.org/Files/files/images/Computer/Screenshots/perl-begin-bad-artif.png" rel="nofollow noreferrer">an image</a> highlighting the undesired effect.</p>
<p>How can I fix the CSS to remedy this problem?</p>

74,612 | <p>I have a table inside a div. I want the table to occupy the entire width of the div tag.</p>
<p>In the CSS, I've set the <code>width</code> of the table to <code>100%</code>. Unfortunately, when the div has some <code>margin</code> on it, the table ends up wider than the div it's in.</p>
<p>I need to support IE6 and IE7 (as this is an internal app), although I'd obviously like a fully cross-browser solution if possible!</p>
<p>I'm using the following DOCTYPE...</p>
<pre><code><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
</code></pre>
<hr>
<p><strong>Edit</strong>: Unfortunately I can't hard-code the width as I'm dynamically generating the HTML and it includes nesting the divs recursively inside each other (with left margin on each div, this creates a nice 'nested' effect).</p>

<pre><code>public static void DoSomething<K,V>(IDictionary<K,V> items) {
items.Keys.Each(key => {

74,625 | <p>A good while ago, I read <a href="http://www.viemu.com/a-why-vi-vim.html" rel="noreferrer">an article by the creator of viemu</a>, clearing up a lot of the misconceptions about vi, as well as explaining why it's a good idea (and why it's been very popular for the last 30 years+). The same guy also has <a href="http://www.viemu.com/a_vi_vim_graphical_cheat_sheet_tutorial.html" rel="noreferrer">a great set of graphical cheat sheets</a> that teach the basics a few bits at a time.</p>
<p>I'm convinced.</p>
<p>I've been convinced for the past 2 years in fact. But I still really haven't gotten around to force myself to learn vi as my primary editor, the learning curve is just too high. When I get down to work, acceptable but immediate productivity (using my current editor) has so far won over tremendous productivity farther down the line (using vi).</p>
<p>Does anybody have any good tips to help get past the learning curve? It can be straight out tips, some other tutorial or article, whatever.</p>
<p>Edit: Note that I'm aware of the <a href="http://www.vim.org/" rel="noreferrer">vim/gVim</a>, <a href="http://cream.sourceforge.net/" rel="noreferrer">Cream</a> and <a href="http://code.google.com/p/macvim/" rel="noreferrer">MacVim</a> (etc.) variants of vi. I kept my question about vi to refer to the vi family as a whole. Thanks for all the great answers.</p>
<h3>Update (April 2009)</h3>
<p>I've been using Vim (more precisely, MacVim) in my day to day professional life since last December. I'm not going back :-)</p>
<p>Good luck to everyone in their Vim mastery.</p>

74,626 | <p>I have a CIFS share mounted on a Linux machine. The CIFS server is down, or the internet connection is down, and anything that touches the CIFS mount now takes several minutes to timeout, and is unkillable while you wait. I can't even run ls in my home directory because there is a symlink pointing inside the CIFS mount and ls tries to follow it to decide what color it should be. If I try to umount it (even with -fl), the umount process hangs just like ls does. Not even sudo kill -9 can kill it. How can I force the kernel to unmount?</p>

74,690 | <p>I have a QMainWindow in a Qt application. When I close it I want it to store its current restore size (the size of the window when it is not maximized). This works well when I close the window in restore mode (that is, not maximized). But if I close the window if it is maximized, then next time i start the application and restore the application (because it starts in maximized mode), then it does not remember the size it should restore to. Is there a way to do this?</p>

74,723 | <p>This problem has been afflicting me for quite a while and it's been really annoying.</p>
<p>Every time I login after a reboot/power cycle the explorer takes some time to show up.
I've taken the step of waiting for all the services to boot up and then I login, but it doesn't make any difference.
The result is always the same: Some of the icons do not show up even if the applications have started.</p>
<p>I've dug a bit on the code that makes one application "stick" an icon in there, but is there an API call that one can perform so explorer re-reads all that icon info? Like invalidate or redraw or something of the sort?</p>
<hr>
<p>Apparently, it looks like Jon was right and it's not possible to do it.</p>
<p>I've followed Bob Dizzle and Mark Ransom code and build this (Delphi Code):</p>
<pre><code>procedure Refresh;
var
hSysTray: THandle;
begin
hSysTray := GetSystrayHandle;
SendMessage(hSysTray, WM_PAINT, 0, 0);
end;
function GetSystrayHandle: THandle;
var
hTray, hNotify, hSysPager: THandle;
begin
hTray := FindWindow('Shell_TrayWnd', '');
if hTray = 0 then
begin
Result := hTray;
exit;
end;
hNotify := FindWindowEx(hTray, 0, 'TrayNotifyWnd', '');
if hNotify = 0 then
begin
Result := hNotify;
exit;
end;
hSyspager := FindWindowEx(hNotify, 0, 'SysPager', '');
if hSyspager = 0 then
begin
Result := hSyspager;
exit;
end;
Result := FindWindowEx(hSysPager, 0, 'ToolbarWindow32', 'Notification Area');
end;</code></pre>
<p>But to no avail.</p>
<p>I've even tried with <pre><code>InvalidateRect()</code></pre> and still no show.</p>
<p>Any other suggestions?</p>

74,782 | <p>What's the difference between eruby and erb? What considerations would drive me to choose one or the other?</p>
<p>My application is generating config files for network devices (routers, load balancers, firewalls, etc.). My plan is to template the config files, using embedded ruby (via either eruby or erb) within the source files to do things like iteratively generate all the interface config blocks for a router (these blocks are all very similar, differing only in a label and an IP address). For example, I might have a config template file like this:</p>
<pre><code>hostname sample-router
<%=
r = String.new;
[
["GigabitEthernet1/1", "10.5.16.1"],
["GigabitEthernet1/2", "10.5.17.1"],
["GigabitEthernet1/3", "10.5.18.1"]
].each { |tuple|
r << "interface #{tuple[0]}\n"
r << " ip address #{tuple[1]} netmask 255.255.255.0\n"
}
r.chomp
%>
logging 10.5.16.26
</code></pre>
<p>which, when run through an embedded ruby interpreter (either erb or eruby), produces the following output:</p>
<pre><code>hostname sample-router
interface GigabitEthernet1/1
ip address 10.5.16.1 netmask 255.255.255.0
interface GigabitEthernet1/2
ip address 10.5.17.1 netmask 255.255.255.0
interface GigabitEthernet1/3
ip address 10.5.18.1 netmask 255.255.255.0
logging 10.5.16.26
</code></pre>

74,790 | <p>Is it possible to listen for a certain hotkey (e.g:<kbd>Ctrl</kbd><kbd>-</kbd><kbd>I</kbd>) and then perform a specific action? My application is written in C, will only run on Linux, and it doesn't have a GUI. Are there any libraries that help with this kind of task?</p>
<p>EDIT: as an example, amarok has global shortcuts, so for example if you map a combination of keys to an action (let's say <kbd>Ctrl</kbd><kbd>-</kbd><kbd>+</kbd>, <kbd>Ctrl</kbd> and <kbd>+</kbd>) you could execute that action when you press the keys. If I would map <kbd>Ctrl</kbd><kbd>-</kbd><kbd>+</kbd> to the volume increase action, each time I press <kbd>ctrl</kbd><kbd>-</kbd><kbd>+</kbd> the volume should increase by a certain amount.</p>

74,847 | <p>Typically I use <code>E_ALL</code> to see anything that PHP might say about my code to try and improve it.</p>
<p>I just noticed a error constant <code>E_STRICT</code>, but have never used or heard about it, is this a good setting to use for development? The manual says:</p>
<blockquote>
<p>Run-time notices. Enable to have PHP suggest changes to your code which will ensure the best interoperability and forward compatibility of your code. </p>
</blockquote>
<p>So I'm wondering if I'm using the best <code>error_reporting</code> level with <code>E_ALL</code> or would that along with <code>E_STRICT</code> be the best? Or is there any other combination I've yet to learn?</p>

74,886 | <p>I need to rearrange some content in various directories but it's a bit of a pain. In order to debug the application I'm working on (a ruby app) I need to move my gems into my gem folder one at a time (long story; nutshell: one is broken and I can't figure out which one).</p>
<p>So I need to do something like:</p>
<pre><code>sudo mv backup/gem/foo gem/
sudo mv backup/doc/foo doc/
sudo mv backup/specification/foo.gemspec specification/
</code></pre>
<p>replacing "foo" each time. How can I author a simple shell script to let me do something like: gemMove("foo") and it fill in the blanks for me?</p>

74,902 | <p>I installed Mono on my iMac last night and I immidiately had a change of heart! I don't think Mono is ready for prime time. </p>
<p>The Mono website says to run the following script to uninstall:</p>
<pre><code>#!/bin/sh -x
#This script removes Mono from an OS X System. It must be run as root
rm -r /Library/Frameworks/Mono.framework
rm -r /Library/Receipts/MonoFramework-SVN.pkg
cd /usr/bin
for i in `ls -al | grep Mono | awk '{print $9}'`; do
rm ${i}
done
</code></pre>
<p>Has anyone had to uninstall Mono? Was it as straight forward as running the above script or do I have to do more? How messy was it? Any pointers are appreciated.</p>

74,951 | <p>Flex has built in drag-n-drop for list controls, and allows you to override this. But they don't cover this in examples. The built-in functionality automatically drags the list-item, if you want to override this you find the handlers are being set up on the list itself.
What I specifically want to do, is my TileList shows small thumbnails of items I can drag onto a large Canvas. As I drag an item from the list, the drag proxy should be a different image.</p>
<p><strong>So, I followed the technique suggested and it only works if I explicitly set the width/height on the proxy Image. Why?</strong></p>

75,014 | <p>In a multi-threaded application I'm working on, we occasionally see <code>ConcurrentModificationExceptions</code> on our Lists (which are mostly <code>ArrayList</code>, sometimes Vectors). But there are other times when I think concurrent modifications are happening because iterating through the collection appears to be missing items, but no exceptions are thrown. I know that the docs for <code>ConcurrentModificationException</code> says you can't rely on it, but how would I go about making sure I'm not concurrently modifying a List? And is wrapping every access to the collection in a synchronized block the only way to prevent it?</p>
<p><strong>Update:</strong> Yes, I know about <code>Collections.synchronizedCollection</code>, but it doesn't guard against somebody modifying the collection while you're iterating through it. I think at least some of my problem is happening when somebody adds something to a collection while I'm iterating through it.</p>
<p><strong>Second Update</strong> If somebody wants to combine the mention of the synchronizedCollection and cloning like Jason did with a mention of the java.util.concurrent and the apache collections frameworks like jacekfoo and Javamann did, I can accept an answer.</p>

75,052 | <p>I have a flash player that has a set of songs loaded via an xml file.</p>
<p>The files dont start getting stream until you pick one.</p>
<p>If I quickly cycle through each of the 8 files, then flash starts trying to download each of the 8 files at the same time.</p>
<p>I'm wondering if there is a way to clear the file that is being downloaded. So that bandwidth is not eaten up if someone decides to click on lots of track names.</p>
<p>Something like mySound.clear would be great, or mySound.stopStreaming..</p>
<p>Has anyone had this problem before?</p>

75,076 | <p>I would like to be able to obtain all the parameter values from the stack frame in .NET. A bit like how you're able to see the values in the call stack when in the Visual Studio debugger. My approach has concentrated on using the <a href="http://msdn.microsoft.com/en-us/library/system.diagnostics.stackframe%28v=vs.71%29.aspx" rel="noreferrer">StackFrame class</a> and then to reflect over a <a href="http://msdn.microsoft.com/en-us/library/system.reflection.parameterinfo%28v=vs.71%29.aspx" rel="noreferrer">ParameterInfo</a> array. I've had success with reflection and properties, but this is proving a bit trickier.</p>
<p>Is there an approach for achieving this?</p>
<p>The code so far looks like this:</p>
<pre><code>class Program
{
static void Main(string[] args)
{
A a = new A();
a.Go(1);
}
}
public class A
{
internal void Go(int x)
{
B b = new B();
b.Go(4);
}
}
public class B
{
internal void Go(int y)
{
Console.WriteLine(GetStackTrace());
}
public static string GetStackTrace()
{
StringBuilder sb = new StringBuilder();
StackTrace st = new StackTrace(true);
StackFrame[] frames = st.GetFrames();
foreach (StackFrame frame in frames)
{
MethodBase method = frame.GetMethod();
sb.AppendFormat("{0} - {1}",method.DeclaringType, method.Name);
ParameterInfo[] paramaters = method.GetParameters();
foreach (ParameterInfo paramater in paramaters)
{
sb.AppendFormat("{0}: {1}", paramater.Name, paramater.ToString());
}
sb.AppendLine();
}
return sb.ToString();
}
}
</code></pre>
<h2>The output looks like this:</h2>
<pre><code>SfApp.B - GetStackTrace
SfApp.B - Go
y: Int32 y
SfApp.A - Go
x: Int32 x
SfApp.Program - Main
args: System.String[] args
</code></pre>
<h2>I'd like it to look more like this:</h2>
<pre><code>SfApp.B - GetStackTrace
SfApp.B - Go
y: 4
SfApp.A - Go
x: 1
SfApp.Program - Main
</code></pre>
<hr/>
<p>Just for a bit of context, my plan was to try and use this when I throw my own exceptions. I'll look at your suggestions in more detail and see if I can see it fitting.</p>

75,105 | <p>I need to store phone numbers in a table. Please suggest which datatype should I use?
<strong>Wait. Please read on before you hit reply..</strong></p>
<p>This field needs to be indexed heavily as Sales Reps can use this field for searching (including wild character search).</p>
<p>As of now, we are expecting phone numbers to come in a number of formats (from an XML file). Do I have to write a parser to convert to a uniform format? There could be millions of data (with duplicates) and I dont want to tie up the server resources (in activities like preprocessing too much) every time some source data comes through..</p>
<p>Any suggestions are welcome..</p>
<p>Update: <strong>I have no control over source data. Just that the structure of xml file is standard. Would like to keep the xml parsing to a minimum.
Once it is in database, retrieval should be quick. One crazy suggestion going on around here is that it should even work with Ajax AutoComplete feature (so Sales Reps can see the matching ones immediately). OMG!!</strong></p>

75,127 | <p>I have a bulletin board (punBB based) that I was running out of the root directory for a couple of years. I foolishly decided to do a little gardening and in the process moved the punbb code into it's own subdirectory. The code works great; as long as you point the browser at the new subdirectory. The issue is that the users expect to see it at the root...</p>
<p>I tried an index file in the root that had the following:</p>
<pre><code><?php chdir('punbb');
include('index.php');
</code></pre>
<p>But that didn't seem to do the trick. So, I tried using the "damn cool voodoo" of mod_rewrite in .htaccess but I can't seem to figure out the right combination of rules to make it work.</p>
<p>Here is what I would like to make happen:</p>
<p>User enters: </p>
<pre><code> http://guardthe.net
</code></pre>
<p>Browser displays: </p>
<pre><code> http://guardthe.net/punbb/
</code></pre>
<p>or</p>
<pre><code> http://punbb.guardthe.net/
</code></pre>
<p>Is this possible, or should I just move the code base back into the root?</p>

75,134 | <p>How do I have two effects in jQuery run in <code>sequence</code>, not simultaneously? Take this piece of code for example:</p>
<pre><code>$("#show-projects").click(function() {
$(".page:visible").fadeOut("normal");
$("#projects").fadeIn("normal");
});
</code></pre>
<p>The <code>fadeOut</code> and the <code>fadeIn</code> run simultaneously, how do I make them run one after the other?</p>

75,139 | <p>Google custom search code is provided as a form tag. However, Asp.net only allows a single form tag on a page. What is the best way to implement their code so you can include it on an aspx page (say as part of a Masterpage or navigation element). </p>
