Hi Rahd,
Have a look at the CREATE CLASS in help file. Basically you can create definitions with code in them and store them in VCX(Class Libraries). When you need to reuse, you simply open the VCX and drop the created control on the form. There is much more than that so I'd suggest you to look into the developer's guide which comes with VFP.
