I think you just need to declare a String to take the result of your CSBuilder. From Erel's
turorial - "A String is one implementation of CharSequence."
So try:
Private cs as CSBuilder
Private str as String = cs.Initialize.....
ListView1.AddSingleLine(str)
'Or you could just:
Private cs as CSBuilder
ListView1.AddSingleLine(cs.Initialize.....)
