Ok, that get me started. Two last questions:

1- Is it possible to make class libraries (including several control subclass like you did) in a single class and then add tjhis class to the toolbox (again like we did in VFP)?

2- Are you starting form a class project or a user control project? I think that the class project is the answer but just to be sure. The user control project would allow me to design the control visually but not to include it in a calss library.

Thank you for your help,
