Hi people! Does enyone know how to launch an external program from a C++/MFC program. Basically, I''m trying to make a small, launcher program for a game I''m working on, which is just a dialog with a few buttons for launching different apps (i.e. a configuration tool and the game itself). Any ideas? Thanks

3 choices, basically(check MSDN for the docs):

* system()
* ShellExecute()
* CreateProcess()

I order you to use _exec(). Or some kind of it.

Know why? Because you''ll be SURE that the parameters are passed CORRECTLY, on any Windows version.

exec-functions maybe wont do what the original poster wants, because they do not return.

Just Depends on the situation :-)

No really. I''ve been working on app/game launchers before. The parameters given did not work on Win98, and when I changed it, it didn''t work on WinXP. -_-''

So _exec()-functions REALLY are appropiate for launchers.

More than that. You could use WinExec()

Cheers guys!!

I tried out _exec and it works like a charm!
Tested it on XP and 2000, and its good on both, but not had chance to try it on a 98 box (but do they exist anymore?)

Woohoo, It''s nearly ready to be released to the public!
