>One of the very first things VFP developers learned when doing OOP was to subclass each and every control they could use in their development efforts.
>So, similar to that, I would like to find out how I subclass forms, textboxes, combo's buttons et cetera and use these in my development efforts instead of the base classes that ship with .NET.
>Preferably I would like to add any of those controls on my (subclassed) forms by Drag and Drop but somehow I feel like this is not possible, or am I wrong (hopefully).

>If anybody out here can enlighten me on how to do this, or point me to sites where this is explained, I would be very greatful.
