GetPixelColor does not work!

[timextreme]

Hey People,

i have a problem and searched long time without any result.

so i using the UDF GetPixelColor to capture a bmp into the memory, that works nice but, pixelgetcolor return always 000000, except the first retun, here i get a hex color value....

i dont understand this, a friend tested it, and he get all color values, do i tried somthing to update my gdi32.dll without success

I use Windows XP Home Edition SP2 ...

$hDll = DllOpen("gdi32.dll")
        $vDC = _PixelGetColor_CreateDC()
        $vRegion = _PixelGetColor_CaptureRegion($vDC,$iLeft,$iTop,$iRight,$iBottom)
        
        If $DebugMode Then logger("debug", "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~")
        If $DebugMode Then logger("debug", "read bitmap to array")  
    ; === read pixels ===
        If $DebugMode And $iShowFillArray Then logger("debug", "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~")
        For $i = 0 to $iHeight-1 Step 1
            For $j = 0 to $iWidth-1 Step 1
                $sColor = _PixelGetColor_GetPixel($vDC, $j, $i, $hDll)
                If $DebugMode And $iShowFillArray Then logger("debug", $i & "->" & $j & " color: " & $sColor)   
                If $sColor = "FFFFFF" Then
                    $Coords[$i][$j] = True
                Else
                    $Coords[$i][$j] = False
                EndIf
            Next
        Next

remember this script work on the other pc, not on mine...

i get these log entries:
