Running DOS commands

[tg2003]

Hello,
I'm a VB programmer, and I have thoughts about using CPP as Back-end of my application (the front-end is VB 6).

I would like to know the following:
1. What is considered the best way for running dos commands from CPP application? my back-end will run dos commands, put its output in files and then manipulates its text.
2. What kind of application should I create by using Visual Studio 6 ? Console application?

Thanks in advance!

System is a way:

The kind of application will depend on how will you execute it.

Cheers,
Dian

Thanks.
I may ask another question: If I run a DOS command that returns output, how can I catch it without of sendind the output to a temporary file?

See MSDN, _pipe() function. Example 2 in the article (too long is exactly the answer...

Dos commands only or execute other applications?

1) If you want dos commands only, I'd rather write some code to do exactly what I want rather than execute a dir /B /S >myfile.txt for example and then reading the file.
2) If you need to run applications consider using CreateProcess (
