File difference algorithm

[paul]

Hello

anyone got an algorithm / source code to compare two text files and show
differences & matches.

Compare by line would be fine, either lines are the same or they are not.

Kind of like WinDiff...

Thanks
Paul

Windiff is available in source code, Winmerge is open source. Classical
copmarison algorirhm is described in Mayers' "An O(ND) Difference
Algorithm and Its Variations" article, which you can find in internet.
I haven't seen any VB code for this.
