What's wrong with my vb C program???
You're not asking for much are you.
NB: Part of your code gets cut off by Y!A then you paste it in, so you might have to rely on the compiler to tell you what's wrong
Reply:Can you add additional infos?? i don't want to read all of them.. When you compile it what does it say?? and what line??
Reply:Do you have a compiler error message; or was it producing an unexpected output? Please provide additional info
Reply:1. What is it supposed to do?
2. What does it do?
3. What errors do you get?
4. Where is the complete source?
