creating Web User Control and adding it to tool box
<p>I'm trying to learn how create a web user control so i can use in diffrent projects.  I created a simple control just to see how it worked; after I created it, I could add it to any page on the current project and it worked fine.  </p>

<p>My problem is how can I add this control to the tool box so I can use it in diffrent projects?  I tried to look for him by doing:</p>

<pre><code>right click toolbox &gt; choose items &gt; looking for it.
I can't see the control in the list. 
</code></pre>

<p>What do i need to add so  i can see it?</p>
