C# .Net lesson that Demonstrates how to execute a program from the command line.
It will open a specified file in window's notepad within a maximized
window.  The program will stop when the user closes the window.

This program could be easily modified to run powerful batch files that
could link resource files - Or a crazy program to annoy your friends that
opens 1000 instances of notepad.
