Vlad,
While controls are windows in environments like VB and VC++ MFC, they are not in VFP. VFP renders a bitmap image of the control and that is what you see. SO there is no window handle to retrieve and manipulate.

I believe this goes back to the lagacy of having to deal with the MAC in VFP 3.0.

You can get window handle of any window and child window (control) using GetNextWindow API funtion (hope I wrote all API function names above correctly, because I have no access to API help files here). It should not be hard:

>- use SetWindowRgn with zero region handle to restore original button
