Comparing 2 jpegs from _ScreenCapture_CaptureWnd

[Spacetech]

I use _ScreenCapture_CaptureWnd to screen capture a window every 5minutes. Is their anyway to compare the 2 images and see if they are the same? I have searched the forums and looked for functions but I haven't found anything on this topic.

You could just do a simple file compare:

If _CompareFiles(@MyDocumentsDir & "\GDIPlus_Image(1).jpg", @MyDocumentsDir & "\GDIPlus_Image(2).jpg") = 1 Then
    ConsoleWrite("+> Files match" & @CRLF)
Else
    ConsoleWrite("-> Files do not match" & @CRLF)
EndIf

Func _CompareFiles ($sFile1, $sFile2)
    Local $hFile1, $hFile2, $bFile1, $bFile2
    $hFile1 = FileOpen($sFile1, 16)
    $hFile2 = FileOpen($sFile2, 16)
    If $hFile1 = -1 Then
        ConsoleWrite('!> Error: Could not open "' & $sFile1 & '"' & @CRLF)
        Exit
    EndIf
    If $hFile2 = -1 Then
        ConsoleWrite('!> Error: Could not open "' & $sFile2 & '"' & @CRLF)
        Exit
    EndIf
    $bFile1 = FileRead($hFile1)
    $bFile2 = FileRead($hFile2)
    If $bFile1 = $bFile2 Then Return 1
    Return 0
EndFunc

every file is different, because every file contains a different creation date.

every file is different, because every file contains a different creation date.

So a FileRead wouldn't work?

Thats why I compared the data in the file, not the file header info. Maybe you should try executing code before you comment.
