All right,
Thanks!

But, can I implement functions/methods of "designed form" on others units?
If I need to access to a component resource of the "design form", I
need to implement it on the unit that contain:

TForm1=class(TMyBaseForm);

right?

So, if I need to access to the properties of a Tbutton that is on the
"designed form", I can't... is it right? How to do?
The question is similar to the one I asked at 16.38.

Kjow :)
