heres the code that i use for put the form transparent:
LONG style= GetWindowLong(hwnd, GWL_EXSTYLE); style=style | WS_EX_LAYERED; SetWindowLong(hwnd, GWL_EXSTYLE, style); SetLayeredWindowAttributes(hwnd, clrBackColor, NULL, LWA_COLORKEY);
but i see problems :(
the form and the controls are showed, but the mouse events are ignored.
if i click on button or form, the form on back(even if it's from another aplication) wins the focus.... why these effect happens?
