under windows: launching an external app via system... but not waiting for a response

Hi,
I have an application written in Ruby (it's actually a windows
service). It needs to launch other applications. The problem I am
having is that when I call system("args to launch app") it never
returns, because I guess the app never returns until it is closed.

I want to be able to launch the app and then continue on.
What is the proper way to do this? A thread?

you can use the "start" windows command, so from your system call you
would call "start" passing the parameters to start your external
application. If you don't want to see a shell window, you can pass /B to
the start command

Do a
system ("start application.exe args to launch app")
