Hi!

There are 2 ways.

One is simple - use bitmaps for image control and change bitmap to 'pressed' bitmap when user presses on control to simulate button functionality. This have disadvantage that any click in the image control will fire clicking event, even when click is outside of triangle.

Another is much more complex, but much more smooth.
You require to make an ActiveX or use existing ActiveX control (Button). Than you require to get windows handle to that button and use Create*Rgn API functions to create reagion you like (Elliptic, triangular etc.), and than SetWindowRgn API function. You will be lucky if it will work, if not - need to write your own painting routine.
