this is not a question, but an application to compare two text files line by line. i attach the project to this post, i also attach two sample text files to compare. these two text files contain the names of the .wav files that comes ready with devices, HandHeld Dolphin 7900 and MC 70.

// i will make the comparison based on the first listbox
// missing lines will be red, added lines to the second listbox will be green
