Running External Applications in ASP.NET

[Edward]

I'm trying to execute an application on the server side in
asp.net. For a simple test, I wanted to run notepad.exe
which I copied from the windows directory to my web app
directory. Here's the code snippet of my webforms
page_load event:
Process myp = new Process();
myp.StartInfo.FileName = "notepad.exe";
myp.StartInfo.WorkingDirectory =
@"c:\inetpub\wwwroot\loanimporttool";
myp.EnableRaisingEvents = true;
myp.Start();

everytime I run this, Notepad runs on the background but
the window doesn't show up. If you try to run the same
code in a windows app, it works. What am I doing wrong?
Any help would be appreciated. Thanks!
