My installation at the moment edits a text file with a path e.g. TARGETDIR+"\\etc" and populates to c:\nexor\etc.

However, due to how our product works we need to either convert the \ to / or have them as \\ in the text file.  Therefore, I'm trying to search for the string \\ which is an escape character for \, in the text file which contains paths with \ and do a WriteLine or FileInsertLine to replace it.  However, the filegrep command doesn't appear to find the instances of it and svReturnLine = "" and nvLineNumber=0.  The output is that it puts a / at the end of the file.  Can any please help as this is quite a severe problem and is starting to become quite annoying.

I've managed to get it to find the string, however it doesn't seem to find all instances of the string.  My next main issue is that it can only append to the end of the line as the functions rely on the line number count.  There must be a way of appending to a string based on character counts.  So that in a line e.g. c:\program files\nexor\etc I can append as c:\\program files\\nexor\\etc rather than what it does at the moment c:\program files\nexor\etc\\.  Here is an example of the code that I have so far
    while (nvLineNumber <= 0)                
    if (FindFile (szPath, "ncs.cfg", svResult) = 0) then    
    if (FileGrep (szNCSPath, szSlashSearch, svReturnLine, nvLineNumber, CONTINUE)=0) then
              OpenFileMode(FILE_MODE_APPEND);      
              OpenFile (nvFileHandle, szPath, "ncs.cfg");
              FileInsertLine (szNCSPath, "\\\\", nvLineNumber, APPEND);
 CloseFile (nvFileHandle);    
     endif;
     endif;  
     endwhile;

You could rewrite the custom action to VBScript, using regular expressions to find and replace characters.

I don't have code at the moment, but if you'd like an example, post a reply and I'll see what I can find.
