Bonnie,

Sorry for adding a message to an old thread.

Could you please tell me how to add your own class library to the VS Toolbox? And, if I do so, will this class library appear in the Toolbox in all my solutions, or just one solution?

Thank you.

>That's it. These controls can't be sub-classed visually, but as you can see, it's easy enough to do it in code. I have all the basic controls sub-classed in one class library file. Once they're added to the ToolBox, then can be dragged onto any design surface in the IDE.
