Activate other process to foreground even it is minimized

Hi friends,
How could I activate other inactive process(application) to active foreground process.?
I need to save an application which is idle for long time (say 30mins).
for example: WINWORD.exe., devenv.exe., notepad.exe., etc., 
Inactive applications are identified from System.Diagnostics.Process class. and For saving I planned to send KeyStrokes. But i didn't work when application(processes) are in minimized mode. So how could I acheive turing back the minimized application to restore mode.
Any help would be appreciateable.

Thanks
