Try it this way:
From the Solution Explorer, right-click on your project where you're keeping all your base classes, choose Add | Windows Form. Now you can open it up in the designer and do whatever you want to it, or put stuff in code. It should show up in your ToolBox, since you already have stuff from this project there (if not, you know how to add it) ... although it really doesn't do you any good in your ToolBox. Did you need to know how to further sub-class this class?
