WinAPI CreateCompatibleBitmap: The specified module could not be found.

[Anbu]

Hi,

I am getting the following error message after running Autoit script.

WinAPI CreateCompatibleBitmap: The specified module could not be found.

In my script I am using Autoit function "_ScreenCapture_Capture".

After saving approximately 900 images, we are getting the error message "WinAPI CreateCompatibleBitmap: The specified module could not be found." and Autoit script starts running.

Because of this problem our script is running for around 5 hours and stops. But our intention is to execute the script, without stopping in the middle.

please provide solution to this problem, so that our script efficiency will increase.

You do not accidentally forget about _WinAPI_DeleteObject()?

Hi,

It is taken care in the following library function available under "Include" folder in istallation directory.

_ScreenCapture_Capture. This function is available in ScreenCapture.au3.

It's a bug. You can submit it (do that really).

Your script will brake because of leaking GDI objects. Replace current _ScreenCapture_Capture() with this one and you will be ok:

Func _ScreenCapture_Capture($sFileName = "", $iLeft = 0, $iTop = 0, $iRight = -1, $iBottom = -1, $fCursor = True)
    Local $iH, $iW, $hWnd, $hDDC, $hCDC, $hBMP, $aCursor, $aIcon, $hIcon

    If $iRight = -1 Then $iRight = _WinAPI_GetSystemMetrics($__SCREENCAPTURECONSTANT_SM_CXSCREEN)
    If $iBottom = -1 Then $iBottom = _WinAPI_GetSystemMetrics($__SCREENCAPTURECONSTANT_SM_CYSCREEN)
    If $iRight < $iLeft Then Return SetError(-1, 0, 0)
    If $iBottom < $iTop Then Return SetError(-2, 0, 0)

    $iW = $iRight - $iLeft
    $iH = $iBottom - $iTop
    $hWnd = _WinAPI_GetDesktopWindow()
    $hDDC = _WinAPI_GetDC($hWnd)
    $hCDC = _WinAPI_CreateCompatibleDC($hDDC)
    $hBMP = _WinAPI_CreateCompatibleBitmap($hDDC, $iW, $iH)
    _WinAPI_SelectObject($hCDC, $hBMP)
    _WinAPI_BitBlt($hCDC, 0, 0, $iW, $iH, $hDDC, $iLeft, $iTop, $__SCREENCAPTURECONSTANT_SRCCOPY)

    If $fCursor Then
        $aCursor = _WinAPI_GetCursorInfo()
        If $aCursor[1] Then
            $hIcon = _WinAPI_CopyIcon($aCursor[2])
            $aIcon = _WinAPI_GetIconInfo($hIcon)
            _WinAPI_DrawIcon($hCDC, $aCursor[3] - $aIcon[2] - $iLeft, $aCursor[4] - $aIcon[3] - $iTop, $hIcon)
            _WinAPI_DestroyIcon($hIcon)
            _WinAPI_DeleteObject($aIcon[4]); <- THIS!
            _WinAPI_DeleteObject($aIcon[5]); <- THIS!
        EndIf
    EndIf

    _WinAPI_ReleaseDC($hWnd, $hDDC)
    _WinAPI_DeleteDC($hCDC)
    If $sFileName = "" Then Return $hBMP

    _ScreenCapture_SaveImage($sFileName, $hBMP)
    _WinAPI_DeleteObject($hBMP)
EndFunc  ;==>_ScreenCapture_Capture

The problem is related to the cursor (I've made a comment pointing to it in the fixed function). Reference is this (remarks section).

Hi,

Thank you, very much.

How to log a defect?

We will test and get back.

Resistance is futile.

Use Bug Reports and Feature Requests section.

Well found.

Another "reference to this" is the AutoIt help file under _WinAPI_GetIconInfo.

Hi,

Sorry. Without the awareness of your bug, I have added a new bug.

Thank you.

[boomingranny]

this bug still exists in the latest version of AutoIT (3.3.4.0), was it re-added somehow?!
