It is not easy to make a program with Visual C++. That you're asking this many questions probably means it is too hard for you. You seem to think that if someone posts a one-line explanation you will know how to make a program. Learning to program takes time though, and requires you to be able to find out things on your own and - when you have a problem - be able to explain it clearly so others can help you.

Right now, your post is not clear at all, to anyone. Nobody will know if you mean the serial to crack Visual C++ so you can use it for free (this is not legal and not tolerated here, btw), the JJ2 source code, the source code of existing JJ2 programs, or the code required to make your own program.
