It is correct for many VFP controls, but not for all, I hope. It seems button, textbox, editbox and many otehr controls are standard windows controls. They rendered, yes, but they probably also have HWND. VFP just allows them to draw self in the memory DC, than applies that DC content together with other drawings (for example, drawings of shapes and grids) to the screen. I will make investigation and let know here. Is it not true? Is it true only for VFP 7?

>> Read help on API functions like CreateEllipticRgn (Create*Rgn), and SetWindowRgn. Note that Button is separate window control that have its own window handle in windows. 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:
>>
>>- Find HWND of button control window
>>- create region for it using Create*Rgn (and some other functions if you want to combine some more complex regions)
>>- use SteWindowRgn to apply region to button
>>- use SetWindowRgn with zero region handle to restore original button
>>- no need to clean up any resources - region will be cleared out automatically when you restore original region or destroy that window (destroy buttn or even form with that button).

The professional level of programmer could be determined by level of stupidity of his/her bugs
It is not appropriate to say that question is "foolish". There could be only foolish answers. Everybody passed period of time when knows nothing about something.
