For VB6 how would u have patches for your game. To fix up game problems. Also how do u have a program for vb only be able to be opened a certain amount of times?

Well depends on your game architecture, a patch generally consist of files which have since the last release.

I don''t understand the other part

Definitely the wrong forum. Game Programming or perhaps general programming.

The best way to plan for patches is to code well enough that altering the code itself is unnecessary. Put all balancing variables and such inside textfiles. That way you can easily tweak them without new executables. Either way, all you need is to update your code and have them overwrite the executable and other files.

To do a run-lock feature involves the registry (the slightly-more-secure way). Or you can just have a file that is opened every time the program is run. The variable inside is incremented by one every time the program runs. If it reaches thirty, say, it will end the program.
