i am having difficulties to write a code that will tell me the amount of lines within 2 files.

I am using nextline() to detect the lines from the 2 files, but when i want to go back to the top of the file and edit something, it wont allow me since i am already at the bottom of the text file.

How would i get around this problem, to check the lines, if its the same on both files?

If you want to know how many lines are in a file, you read that file, a line at a time, and keep a count as you go.

If you want to edit the file, you read the file in, change the lines you want to change, and write the file back out.

You can do both at the same time if the editing doesn't depend on the number of lines. If it does depend on it, then you'll have to make two passes.
 
I agree. Here's the link: http://aspose.com/file-tools
