<p>I am developing a piece of software in Python that will be distributed to my employer's customers. My employer wants to limit the usage of the software with a time-restricted license file.</p>
<p>If we distribute the <code>.py</code> files or even <code>.pyc</code> files it will be easy to (decompile and) remove the... | <p>Python, being a byte-code-compiled interpreted language, is very difficult to lock down. Even if you use a exe-packager like <a href="http://py2exe.org" rel="noreferrer">py2exe</a>, the layout of the executable is well-known, and the Python byte-codes are well understood.</p>

<p>My asp.net mvc site needs some kind of authorization but it is rather different than the usual concept of users and thus membership.
It will be used more for preferences then for authentication actually. Accounts without any password should be possible (and will initially be the only type) and an account can also be... | <p>You could use the standard Membership provider and using the Built in .Validate() method sending the Username and a Password that is "standard" for all accounts without authentication.</p>

<p>How can I tell if SP1 has been installed on VS2008? e.g. If I'm working on a co-worker's machine - how can I tell if he/she has installed SP1 for VS2008?</p>

<p>Not sure what exactly is going on here, but seems like in .NET 1.1 an uninitialized event delegate can run without issues, but in .NET 2.0+ it causes a NullReferenceException. Any ideas why. The code below will run fine without issues in 1.1, in 2.0 it gives a NullReferenceException. I'm curious why does it behav... | <p>[updated] AFAIK, there was no change here to the fundamental delegate handling; the difference is in how DataTable behaves.</p>
<p>However! Be very careful using static events, especially if you are subscribing from instances (rather than static methods). This is a good way to keep huge swathes of objects alive and... | <p>The way events work hasn't really changed from 1.1 to 2</p>
<p>Although the syntax looks like normal aggregation it really isn't:</p>

dt.RowChanged += null;
dt.RowChanged += delegate (object sender, DataRowChangeEventArgs e) {
//anon
};

<p>In Microsoft IL, to call a method on a value type you need an indirect reference. Lets say we have an ILGenerator named "il" and that currently we have a Nullable on top of the stack, if we want to check whether it has a value then we could emit the following:</p>
<pre><code>var local = il.DeclareLocal(typeof(Nulla... | <p>If the variable is already on the stack, you can go ahead and just emit the method call. </p>
<p>It seems that the constructor doesn't push the variable on the stack in a typed form. After digging into the IL a bit, it appears there are two ways of using the variable after constructing it. </p>

<p>I want to send an array constructed in javascript with the selected values of a multiple select. Is there a way to send this array to a php script using ajax?</p>
| <p>You can post back to your server with XML or JSON. Your javascript will have to construct the post, which in the case of XML would require you to create it in javascript.
