Best Shell & Wait (No API's!)
Makes it easy to perform a clean "Shell & Wait" where your applicatoin kicks off an external application and waits for it to return before continuing. Many shell & wait examples I have found tend to overdrive the proccessor in a loop or require you to make API calls. This one uses the Windows Script object to take advantage of it's built-in wait parameter on the .Run method...scripting's version of Shell.
