Executing Programs Within Code

I want to write a program that runs different programs depending on user input. How on earth do I do this?

Using C++ by the way...

The easiest way in windows is probably the system() function:

int system(const char *command);

The command string is the command to run, for example:

system("C:FooMyProgram.exe");

sick...do I have to #include anything special?

Noooooo! That should be ! isn't even standard! Bad Big J! *slaps wrist*

If you want more control (and are planning to only run in windows) ShellExecute[Ex] is an alternative.

fork isn't available in windows. I think the (somewhat) equivalent is _spawn() ??

fork only creates another process anyway, you'd manually also have to load the executable code into that process and get it running. Using the system call or the windows only ShellExecute is preferred and much simpler.

Hmm.. Not so sure about fork..

And Yes, sorry about . Was going from memory, haven't used system() for a while. I would normally use ShellExecute[Ex].

Well, you know what they say... "When all you have is a fork, everything looks like a process..." or something...

mem wars flash back, take both branches (and fork)

I prefer to use CreateProcess() gives you more control when starting it.
