I am a beginner in Visual C++.

I am trying to execute a MS DOS program, because I need to generate a fast signal (80 microseg.) through LPT.
I think I need to use runtime libraries.
Anyway, I am not able to link my program with any options.

I hope one of you could help me.

Resumming,
I need to do "inp", disabling windows.

Thanks in advance.

visual C++ does not generate DOS programs.  It can generate win32 console programs that look like DOS programs (to the user, and somewhat to the programmer)  however, they are very different in nature.

You can use the _inp() and _outp() procedures from a VC console application.  You need to include the <conio.h> file.  these procedures are very slow and extremely inefficient however.  If you need fast access they are not going to work for you.

The run-time library will be linked in automatically.

What do you mean by "stop"?

In windows 95, you can shut down windows and restart in MS-DOS mode.  This option appears when you try to shut down windows.  You cannot do that from NT however.  However, the program you are creating won't run in DOS mode.  It is not a DOS program, it is a windows program.  VC cannot create DOS programs, only windows programs.
