Triggering haslayout in IE 6, what's the side effect of using * html div { height: 1%; } <p>For a while, I've been putting * html div { zoom: 1; } in my base stylesheet, and it has worked great. However, I now run into situations where there're elements that are absolute positioned that are losing their heights and wid... | <p>This is known as <a href="http://www.communitymx.com/content/article.cfm?page=2&cid=c37E0" rel="nofollow">The Holly Hack</a>. As far as I know, there isn't a side effect, especially if you <code>* html</code> it for IE6 directly. I agree with the other posters that placing it on the <code><div></code> tag ... |
resume/suspend enery star linux from command line <p>I have an ssh connection to a linux machine which is hibernated after some non-activity time.</p>
<p>I want to make it resume, how do I do that?
(writing to /dev/mouse to simulate mouse movement didn't do the trick)</p>
| <p>A machine that is hibernating cannot come out of sleep without pressing the power button, or sending a magic packet if the ethernet adaptor has Wake On Lan (WOL) capability and the motherboard supports that. WOL packets can only be generated on the local network, not remotely from other networks.</p>

Huge main.cs file <p>I am new to C# (coming from Delphi) and find my main.cs file becoming quite large. In Delphi I can create classes in a .pas file and use it from my main application file. I simply add the uses (filename) keyword.</p>
<p>My question is how do I do something similar in C#? Example:</p>
<p>Delphi:</... | <p>First, you need to make sure you're in the same namespace:</p>
<pre><code>namespace mynamesspace {
</code></pre>
<p>Next, if your class members are declared privately, you need to indicate you're working on that class:</p>
<pre><code>public partial class frmMyForm : Form {
</code></pre>
<p>Note though, that this... |
SQL Express remote access <p>Is there any way to install SQL Express 2005 silently while configuring to allow remote access, or must the configuration be done with the SQL Server Management Studio UI?</p>
| <p>After the SQL Service is installed log into the database and run the following and then restart the SQL Service.</p>
<pre><code>exec sp_configure 'remote access', 1
reconfigure
</code></pre>
<p>This will allow remote access to the service. If you are installing a named instance you'll need to ensure that the SQL ... |
static vs extern "C"/"C++" <p>What is the difference between a static member function and an extern "C" linkage function ? For instance, when using "makecontext" in C++, I need to pass a pointer to function. Google recommends using extern "C" linkage for it, because "makecontext" is C. But I found out that using static... | <p>Yes, you are just lucky :) The extern "C" is one language linkage for the C language that every C++ compiler has to support, beside extern "C++" which is the default. Compilers may supports other language linkages. GCC for example supports extern "Java" which allows interfacing with java code (though that's quite cu... |
