Hello everyone,

Im trying to make a macro via PostMessage. For a start i want to make a simple mouseclick ingame. First I found what kind of messages I need to do that these are:

WM_LBUTTONDOWN
WM_NCHITTEST
WM_SETCURSOR
WM_LBUTTONUP

So I get handle of game window via FindWindow and call PostMessage

invoke PostMessage,[Handle],WM_LBUTTONDOWN,MK_LBUTTON,[xy]
invoke PostMessage,[Handle],WM_NCHITTEST,0,[xy]
invoke PostMessage,[Handle],WM_MBUTTONUP,MK_LBUTTON,[xy]

and the problem is

nHittest = LOWORD(lParam); // hit-test code
wMouseMsg = HIWORD(lParam); // mouse-message identifier

hit test code is a string, such as HTCLIENT and mouse message ID is 512 but it seems to change even when the same message sequence is sent.

My question is how to combine string and number into one DWORD to send WM_SETCURSOR, also im not sure if this will work, so please help if you know more about simulating mouse clicks in asm, thanks.
