How to call an .exe file from VB?

I got an application (.exe) I want to fire up from my program. I would like to just click a command button and call the .exe.

Use SHELL function.
Description - in VB help.
Example :
' Specifying 1 as the second argument opens the application in
' normal size and gives it the focus.
Dim RetVal
RetVal = Shell("C:\WINDOWS\CALC.EXE", 1) ' Run Calculator.
