How can I run an EXE from within my application

Use the Process class found in the System.Diagnostics namespace.

[C#]
	Process proc = new Process(); 
 	
 	proc.StartInfo.FileName = @'Notepad.exe'; 
 	proc.StartInfo.Arguments = ''; 
	proc.Start(); 

[VB.NET]
	Dim proc As New Process()

	proc.StartInfo.FileName = 'Notepad.exe'
	proc.StartInfo.Arguments = ''
	proc.Start()
