You seem to be picking up programming really quickly :)
I will need to check up how to access the designer produced code from your other thread - I know how to do it in C#, but I have a suspicion that it is different in VB.
Basically, the gist of it is that you are going to have to create an array of old names, and an array of new names, loop through the old names, and convert each to the new name.
What format exactly does this file take? It is something like (with \t for a tab, and \r\n for a newline)
I can then talk you through it. Very well done for the impressive results you have already achieved.
