Hi Peter,
After a quick look to Win32 SDK, I think you already have the winner here.
After you install a mouse hook (see SetWindowsHookEx - WH_MOUSE) your
application will get notifications in the form of this record:
typedef struct tagMOUSEHOOKSTRUCT {
POINT pt;
HWND hwnd;
UINT wHitTestCode;
DWORD dwExtraInfo;
}
"pt" tells you the coordinate of the mouse, and "hwnd" tells you window handle
that is receiving the mouse message (i.e. directly under the cursor). Now you
can check if "pt" is within your application windows territory or not. If so,
you then you check if hwnd is your window or not (compare result from win32 api
GetWindowThreadProcessId of that hwnd against your application process id).
Regards,
Luthfi B Hakim
