File Read Filtering

[Hadez]

Thank you all for your help. I managed to solve it with your help, although my method was a little noob like It is kind of based on:

Local $avArray[4]

$avArray[0] = ".jpg"
$avArray[1] = ".png"
$avArray[2] = ".gif"
$avArray[3] = ".bmp"
;ect...

$line = FileReadLine($filename)
For $i = 0 to UBound($avArray) - 1
    If StringInStr($line,$avArray[$i]) > 0 Then
        FileDelete($filename)
        Return ;Go back to While 1
    EndIf
Next
;rest of processing

But i cudnt quite work that out, so used a basic version of it:

While 1
    Search()
WEnd

Func Search()
    $chkNewFileLocation = FileFindFirstFile($chkPath & "\*.txt")
    If $chkNewFileLocation = -1 Then
        Sleep(10000)
        Return
    EndIf
    While 1
        $chkNewfile = FileFindNextFile($chkNewFileLocation)
        $chkNewFilePath = $chkPath & $chkNewFile
        $filetypecheck = Fileread($chkNewFilePath)
        $oofiletype = StringRight($filetypecheck, 4)
        If $oofiletype = ".png" Then
            Filedelete($chkNewFilePath)
            Return
            elseif $oofiletype = ".gif" Then
            Filedelete($chkNewFilePath)
            Return
            elseif $oofiletype = ".jpeg" Then
            Filedelete($chkNewFilePath)
            Return
        Endif
        msgbox(0,"Success","This works ok so continue procesing") ; rest of processing follows
        Sleep(10000)
    WEnd
EndFunc

seems like the StringRight solved the problem. Thanks for also explaining Return. The biggest problem for me was to get back to while 1, which return solved. Thanks for all your help
