Can't read the tab spaces from a file.

I'm trying to read from a log file stored on my PC. The log contains tab spaces and I want to read those as well. I use the ReadLine() method to read the line that I want, but it doesn't read the tab...

    The file is read correctly. What you see is the log viewer stripping the whitespace - this is how it works. But if you check the individual characters in a string, you'll see the tabs (code 9) are there:

     

    s = F.ReadLine();
    Log.Message(s);

    for (var i = 0; i < s.length; i++)
      Log.Message(s.charAt(i) + " (code " + s.charCodeAt(i) + ")");

Can you show the code you're using, and attach a sample file?

...

F = aqFile.OpenTextFile(fileArray.pop(), aqFile.FaRead, aqFile.ctANSI);

while(!F.IsEndOfFile())

{

   s = F.ReadLine();

   ...

   Log.Message(s);

}

 

I tried Log.Message(F.ReadLine()); to see if for some reason the variable can't hold the tabs, but it seams that the method is not reading the tab spaces. I tryed all 3 TextCodingType, still same result.

      Yes, you are right. When I write the text to a file, the tabs are there.

      Thank you.
