Open app with Run dialog

[TimeHero]

Hi!
I'm working on a small application (for personal use) to quickly open an application, just like the Run dialog.
In the app I have a textbox where I input the application name and when I press "Enter" it should try to open the application with the Run dialog and if it aren't there I am going to search My Documents, but that's a later problem. Right now I want to know how I automaticly input a string in to the Run prompt.
Thanks!
