What would be the syntax for SendMessage when the message has Hiword and Loword in its wParam ??

SendMessage, 0x111, ????, %hwndcontrol%, A

Thanks for any suggestions !

LoWord := 1
HiWord := 2

wParam := MakeLong( LoWord, HiWord ) 
SendMessage, 0x111, %wParam%,0, %hwndcontrol%, A

MakeLong( LoWord, HiWord ) {
 return (HiWord << 16) | (LoWord & 0xffff)
}

Thanks

LoWord := 1
HiWord := 2

wParam := MakeLong( LoWord, HiWord ) 
SendMessage, 0x111, %wParam%,0, %hwndcontrol%, A

MakeLong( LoWord, HiWord ) {
 return (HiWord << 16) | (LoWord & 0xffff)
}

How would you do the conversion backwards? The OnMessage for 0x200 (WM_MouseMove) gives the X and Y coords, but as HiWord and LoWord; when I saw this I decided to just use MouseGetPos instead but if I could use it from the system that would be even better.

Seems like I should be able to figure out how to reverse it from the code you posted, but I'm absolutely terrible with bit-wise operations x_x

Edit: Nevermind, managed to figure it out (I think). I have this, and it works for a couple examples, so hopefully it's been done how it should:

MakeShort( Long , ByRef LoWord, ByRef HiWord) {
 LoWord := Long & 0xffff
 HiWord := Long >> 16
}

That is the correct method and I have been using it for a long time.

Yay! I guess I probably should have done a forum search for Hi-/LoWords before just going to MouseGetPos... Ah well. Thanks for the help.
