First up, it's not a UserControl. A UserControl is a class that inherits UserControl.

As for the question, you're trying to turn something easy into something difficult. You simply add a new class to your project with the appropriate name, add your code to the code file when it opens and then build the project. That's all there is to it.

I'm not sure if this is what your talking about about? Here's a screenshot example in VS 2008. (Fundamentally the same in 2010)

like jmcilhinney said:

so.. create a vb code file, add your code to it and then Build. After building it the components should show up in your toolbox like shown. Remember to Rebuild each time you edit the code though.
