' This VB class module, shows how to get:
' * Total playing time, in seconds, of any stream/music
' * Playing position in seconds
' * A function that will convert total seconds into:
' Hours:Minutes:Seconds [01:25:50]
' * and much more... :)
'
' * Some functions are based on Ian Lucks 'C' examples!
