Window Capture

[MasonMill]

Hey Guys,

I want to display the client window but when I use _ScreenCapture_CaptureWnd it captures the border and title bar and everything with it. Im trying to find coordinates of things relative to that client but I cant get it relative to the client becasue the window border is imaged too. I found a previous topic on the forums but the question was never answered. Any ideas?

This is how I changed the example within the help file:

expandcollapse popup

Func Example()
    Local $hGUI, $hBMP, $hBitmap, $hGraphic, $hImage, $iX, $iY, $hClone, $fileloc=@ScriptDir&"\SOMEclient.bmp",$iLeft,$iTop,$iRight,$iBottom,$bCursor

    ; Create GUI
    $hGUI = GUICreate("GDI+", $ClientSize[0], $ClientSize[1])
    GUISetState(@SW_SHOW)

    ; Initialize GDI+ library
    _GDIPlus_Startup()

    ; Capture 32 bit bitmap
    ;$hBMP = _ScreenCapture_Capture("")
    $hBMP = _ScreenCapture_CaptureWnd ( "" , $hSOMEclientWin ); MY AUGMENTATION!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    $hImage = _GDIPlus_BitmapCreateFromHBITMAP($hBMP)

    ; Create 24 bit bitmap clone
    $iX = _GDIPlus_ImageGetWidth($hImage)
    $iY = _GDIPlus_ImageGetHeight($hImage)
    $hClone = _GDIPlus_BitmapCloneArea($hImage, 0, 0, $iX, $iY, $GDIP_PXF24RGB)

    ; Save bitmap to file
    _GDIPlus_ImageSaveToFile($hClone, @ScriptDir & "\GDIPlus_Image.bmp")

    ; Clean up resources
    _GDIPlus_BitmapDispose($hClone)
    _GDIPlus_BitmapDispose($hImage)
    _WinAPI_DeleteObject($hBMP)

    ; Draw bitmap to GUI
    $hBitmap = _GDIPlus_BitmapCreateFromFile(@ScriptDir & "\GDIPlus_Image.bmp")
    $hGraphic = _GDIPlus_GraphicsCreateFromHWND($hGUI)
    _GDIPlus_GraphicsDrawImage($hGraphic, $hBitmap, 0, 0)

    ; Clean up resources
    _GDIPlus_GraphicsDispose($hGraphic)
    _GDIPlus_BitmapDispose($hBitmap)

    ; Shut down GDI+ library
    _GDIPlus_Shutdown()

    ; Loop until the user exits.
    Do
    Until GUIGetMsg() = $GUI_EVENT_CLOSE
EndFunc   ;==>Example

Thanks,

How do you know what the client window is?

You can enumerate all open visible windows, search for client window and pass the handle to _ScreenCapture_CaptureWnd.
 

#include <Array.au3>
#include <WindowsConstants.au3>
#include <WinAPI.au3>

GetAllWindow()

Func GetAllWindow() ;code by Authenticity - modified by UEZ
    Local $aWin = WinList(), $aWindows[1][4]
    Local $iStyle, $iEx_Style, $iCounter = 0
    Local $i, $aWinPos

    For $i = 1 To $aWin[0][0]
        $iEx_Style = BitAND(_WinAPI_GetWindowLong($aWin[$i][1], $GWL_EXSTYLE), $WS_EX_TOOLWINDOW)
        $iStyle = BitAND(WinGetState(HWnd($aWin[$i][1])), 2)
        If $iEx_Style <> -1 And Not $iEx_Style And $iStyle Then
            $aWinPos = WinGetPos($aWin[$i][1])
            If $aWinPos[2] > 1 And $aWinPos[3] > 1 Then
                $aWindows[$iCounter][0] = $aWin[$i][0]
                $aWindows[$iCounter][1] = $aWin[$i][1]
                $aWindows[$iCounter][2] = $aWinPos[2]
                $aWindows[$iCounter][3] = $aWinPos[3]
                $iCounter += 1
            EndIf
            ReDim $aWindows[$iCounter + 1][4]
        EndIf
    Next
    ReDim $aWindows[$iCounter][4]
    _ArrayDisplay($aWindows)
    Return $aWindows
EndFunc   ;==>GetAllWindow

Ahh, you have to define the style of window. Thank you very much!
