Myself and another are writing a chat program and we want to be able to launch games from it. We can already take people from the chat room and launch tem into directplay games, btu games like rogue spear and quake 3 we dont know that is done. If anyone knows how it is done and knows where we can get the API calls to launch a group of people into thes.e non directplay games please contact me at email@example.com
If you want to launch an executable use either ShellExecuteEx or CreateProcess (if you either want a lot of control over the spawned process or feel like a badass). I don''t know how you would put them into a game from there though.
