Here's what I am trying to do. I have a text file that has a URL path and a destination path. Based on what OS, I'd like it to automatically change the destination path in the file. Here is the code I am trying to use.

Code:

Function Change_Text

	$sMyFile = @SCRIPTDIR + '\xfer.txt'
	
	If Exist($sMyFile)
		
		$sOldString1="%" + "windir" + "%"
		Select
			Case InStr(%windir%,"\Windows")
				$sNewString= %systemdrive% + "\Windows"
			Case InStr(%windir%,"\WinNT")
				$sNewString= %systemdrive% + "\WinNT"
			Case 1
				$sNewString = %systemdrive% + "\Temp"
		EndSelect
				
		$msg = MessageBox("Old string = " + $sOldString1 + @CRLF +
								"New string = " + $sNewString,"Notice",64)
								
		Exit

		For Each $sSection in Split(ReadProfileString($sMyFile,"",""),Chr(10))
   		If $sSection
;      		"Checking section "+$sSection+@CRLF
      		For Each $sEntry in Split(ReadProfileString($sMyFile,$sSection,""),Chr(10))
         		If $sEntry
            		$sValue=ReadProfileString($sMyFile,$sSection,$sEntry)
;            		"Entry "+$sEntry+" has value "+$sValue+" status:"
            		If $sValue=$sOldString1; Or $sValue=$sOldString2 Or $sValue=$sOldString3
;              		" **UPDATED**"+@CRLF
							$=WriteProfileString($sMyFile,$sSection,$sEntry,$sNewString)
            		Else
;           			" No change"+@CRLF
            		EndIf
         		EndIf
      		Next
   		EndIf
		Next
	EndIf

EndFunction


Here is the text file http://upload.dataspike.org/files/1/xfer.txt (right click, save-as)

However, when I run the function it doesn't do anything. I know the commands are based off of using an INI type format with sections and what not, but with this file being read by an external application, I can't have any of those sections, it has to be formatted exactly as it is.

Any help, and or suggestions would be awesome!

Thanks,
Chris
