  1. have a look to the code below. I changed the lines accordingly where you now can read about it in the help file
  2. this line is used to get the screen size incl. 1+ monitors. Also check out the help file for more information

 

#include <GDIPlus.au3>

_GDIPlus_Startup()
Global $handle = WinGetHandle("[CLASS:Notepad]")
Global $hBitmap = Capture_Window($handle, _WinAPI_GetWindowWidth($handle), _WinAPI_GetWindowHeight($handle))
_GDIPlus_ImageSaveToFile($hBitmap, @ScriptDir & "\test.jpg")
_GDIPlus_Shutdown()

ShellExecute(@ScriptDir & "\test.jpg")


Func Capture_Window($hWnd, $w, $h)
    If Not IsHWnd($hWnd) Then Return SetError(1, 0, 0)
    If Int($w) < 1 Then Return SetError(2, 0, 0)
    If Int($h) < 1 Then Return SetError(3, 0, 0)
    Local Const $hDC_Capture = _WinAPI_GetDC(HWnd($hWnd))
    Local Const $hMemDC = _WinAPI_CreateCompatibleDC($hDC_Capture)
    Local Const $hHBitmap = _WinAPI_CreateCompatibleBitmap($hDC_Capture, $w, $h)
    Local Const $hObjectOld = _WinAPI_SelectObject($hMemDC, $hHBitmap) ;DllCall("gdi32.dll", "int", "SetStretchBltMode", "hwnd", $hDC_Capture, "uint", 4)
    _WinAPI_SetStretchBltMode($hDC_Capture, $STRETCH_HALFTONE) ;DllCall("user32.dll", "int", "PrintWindow", "hwnd", $hWnd, "handle", $hMemDC, "int", 0)
    _WinAPI_PrintWindow($hWnd, $hMemDC)

    _WinAPI_DeleteDC($hMemDC)
    _WinAPI_SelectObject($hMemDC, $hObjectOld)
    _WinAPI_ReleaseDC($hWnd, $hDC_Capture)

    Local Const $hFullScreen = WinGetHandle("[TITLE:Program Manager;CLASS:Progman]")
    Local Const $aFullScreen = WinGetPos($hFullScreen)
    Local Const $c1 = $aFullScreen[2] - @DesktopWidth, $c2 = $aFullScreen[3] - @DesktopHeight
    Local Const $wc1 = $w - $c1, $hc2 = $h - $c2

    If (($wc1 > 1 And $wc1 < $w) Or ($w - @DesktopWidth > 1) Or ($hc2 > 7 And $hc2 < $h) Or ($h - @DesktopHeight > 1)) And (BitAND(WinGetState(HWnd($hWnd)), 32) = 32) Then
        Local $hBmp_t = _GDIPlus_BitmapCreateFromHBITMAP($hHBitmap)
        $hBmp = _GDIPlus_BitmapCloneArea($hBmp_t, 8, 8, $w - 16, $h - 16)
        _GDIPlus_BitmapDispose($hBmp_t)
    Else
        $hBmp = _GDIPlus_BitmapCreateFromHBITMAP($hHBitmap)
    EndIf
    _WinAPI_DeleteObject($hHBitmap)
    Return $hBmp
EndFunc   ;==>Capture_Window

 

Within the function GDI and GDIPlus functions are used. $hHBitmap is in GDI format whereas $hBmp is in GDI+ format.

 

I would suggest to dig in the help file to get a better understanding...

 

Have fun. :)
