Hi all, been trying to work out how to do this:
Code: Select all
PostMessage_(hWnd,#WM_MOUSEMOVE,#MK_LBUTTON,new_mousex_and_mousey_go_here)
And according to
http://winapi.freetechsecrets.com/win32 ... SEMOVE.htm I need to put the new X and Y mouse values for the "lParam" paremeter at the end. How do I do that? Do I make those into a point structure or something? It seems like I do, but I'm not 100% sure? I feel like I'm so close but can't work it out. Thanks.

Code: Select all
Macro HiWord(a)
((a) >> 16 & $ffff)
EndMacro
Macro LoWord(a)
((a) & $ffff)
EndMacro
Macro MakeParam(LoWord, HiWord)
((HiWord) << 16 | (LoWord))
EndMacro

Thanks, Rinzwind. It doesn't move the mouse like I hoped, though. Will have to settle for SetCursorPos_() instead.

Little bugfix. So works with signed lowords
Code: Select all
Macro HiWord(a)
((a) >> 16 & $ffff)
EndMacro
Macro LoWord(a)
((a) & $ffff)
EndMacro
Macro MakeParam(LoWord, HiWord)
(HiWord << 16 | (LoWord & $FFFF))
EndMacro
Debug MakeParam($8000, 0)
