Activity/Inactivity Monitor for Application or Global

'************************************************************
'HOW TO USE THIS CODE
' 1. ADD a Timer Control with name ActivityTimer on form with 100 millisecond interval
' 2. ADD a Label with name label1
' 3. COPY and PASTE this code into your code in the form where the above controls are added
