How to hide a program?

[jvdb]

Hi all,

I've created a program that receives files and opens the corresponding
program (for example adobe acrobat). However, when started, i would
like to see nothing of the running program. I only want to see the
program that will be opened.
Is it possible to start a program 'hidden' or minimized to at least
the system tray? And, if yes., could some one help me on this?

Thanks already!
