Let me show you the prototype of WindowFromPoint:
Code:
HWND WindowFromPoint(

    POINT Point         // structure with point
   );    


Tomasz: You had set a wrong amount of params to that function, it needs only one param not two.

Regards,

and the point structure is correct.
Code:
typedef struct tagPOINT { 
  LONG x; 
  LONG y; 
} POINT, *PPOINT;

locodelassembly: I also had some problems with this API once, but I noticed that API reference says "POINT" (structure) not "LPPOINT" (long pointer to structure). Heh, but for someone who doesn't use this API it could not be clear at first Smile
