No, not on XP.
It does not support desktop composition.
But Vista does( only with Aero enabled - the DWM API ).

if i set my window to an layered window, alpha blending and semi-transparence works fine, but my controls are away...
the funktions i use are
SetWindowLong();
UpdateLayeredWindow();
and it must work on xp, because konfabulator widgets and yahoo widgets do it on winxp.
isn't there source code available for this widget engines or does somebody know how they do this?
