Hi Roman,

In my experienced, I never had trouble with CreateProcess. Just be careful if you set "No Window" in Startup_Info, your process must quit it's process correctly without user intervention, or else you have to kill it with Ctrl-Alt-Del or programmaticaly.

I'm not really sure what you mean with "pass data". Can you just pass it as a string (by refference) in a parameter ?
