drawing on another applications window

[Traddles]

I want to write a script that involves drawing on another applications window (or at least giving the appearence of doing so) is there a way to do this, or a way to make my window invisible (so I can see through it to what's behind it) and just draw visibly on my window?

Fairly simple. You'll need Auto3Lib for the API calls:

#include <A3LWinAPI.au3>

Global $hWnd, $hDC, $tRect

Run("Notepad.exe")
_Lib_WinWaitActive("Untitled - Notepad")
$hWnd  = WinGetHandle("Untitled - Notepad")
if @Error then _Lib_ShowError("Unable to get Notepad window handle")

$hDC = _API_GetDC($hWnd)
$tRect = __tagRECT()
_tagSetData($tRect, "Left"  , 100)
_tagSetData($tRect, "Top"   , 100)
_tagSetData($tRect, "Right" , 400)
_tagSetData($tRect, "Bottom", 160)
_API_DrawText($hDC, "DrawText demo", $tRect, 0)

what is A3LWinAPI.au3? I couldn't find any documentation for it or even the actual file.

ahhh, I searched around the forums and saw that file, I didn't know that A3LWinAPI.au3 was a part of that package...

thanks for your help guys, I'll have to go mess around with that api for a while.
