app not showing up when call in webservice with process.start(calc.exe);

Question

All Built a webservice that calls calc.exe using process.start(calc.exe); The app shows in task manager but the calculater screen doesn't pop open. Why is that? Is there a property that I need within the Process object? Its my understanding that we can't use Shell commands in C# can I use the old Com namespace? I just proved it works fine in a windows application why doesn't it work in a webservice?

Realgar · Answer

it is probably because the calc.exe is running under a different user so you can´t see it I know that trying to do it under asp.net web app will launch the application under the asp.net user so you can´t see it running.
