Search text and loop in multiples files

Recommended Posts

Hi there!

I need to add a special disclaimer in emails signatures users.
It's easy to add the message, but I want to check before if the message exist in HTML files.(My users have more than one signatures / html files)
My condition to search and stop do not works correctly, it stop on the first html file if the condition is true, but do not search and the second HTML file.
The goal is to add the message on every signature in the folder, but only one time of course. (This condition is important if the flag is not working and if we deploy the script again.)

Here is my code, what is wrong ?

$sFind = "</div>"
$sFilename = _FileListToArray(@AppDataDir & "\Microsoft\Signatures\", "*.htm", 1, True)

For $i = 1 To $sFilename[0]
$search = "If you read this message, you are the winner"
Global $iLine = 0, $sLine = '', $iValid = 0
$hFile = FileOpen($sFilename[$i])

; find the line that has the search string
While 1
    $iLine += 1
    $sLine = FileReadLine($hFile)
    If @error = -1 Then ExitLoop

    ; test the line for the $search string until the flag $iValid is set
    If StringInStr($sLine, $search) And Not $iValid Then
        $iValid = 1

    If $iValid Then
        $iValid += 1
        ConsoleWrite($iLine & ':' & $sLine & @CRLF)
        If $iValid = 1 Then ExitLoop


For $i = 1 To $sFilename[0]

$iMsg = @CRLF
$iMsg &="<p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-size:14.0pt;font-family:""Lucida Sans Unicode"";color:black'>If you read this message, you are the winner....</span></p>" & @CRLF
$iMsg &= "</div>" & @CRLF

$iRetval = _ReplaceStringInFile($sFilename[$i], $sFind, $iMsg)



Thanks !!
