Semi-Transparent Button created by "CreateWindowEx" !!

I have created  a "Button" class window via "CreateWindowEx" API.

what I want is to have this newly created button to be Semi-Transparent  by setting its WS_EX_LAYERED Window Style and then using the "SetLayeredWindowAttributes" API.

I am not sure if the button needs to be subclassed or or maybe I should capture the WM_CREATE Message in its window procedure and if that's the case can anyone show me how.

Anyway, I have tried many things but without any luck.

Can anybody show me a working code snippet to solve this  ?

BTW, SetLayeredWindowAttributes will only run on OS Win2000 or above.
