Hello,
I'm planning to write a back-end by using CPP (with Visual Studio), while the front-end is VB 6.
I have some questions about the CPP, thanks in advance:

1. If I make an EXE of the CPP, is there any limitation of number of arguments after the exe name (e.g. c:\my_app 1 2 3 4 ...) ?
2. How do I get the type of Operating System inside my code?
3. If I run a DOS command that returns output, how can I catch it without of sendind the output to a temporary file?
