Gianluigi,

Thanks for your app showing the use of class. I've amended your app for 
sorting corresponding arrays. I've amended it so that it sorts on a 
composite key (Series Name padded out to 15 characters with spaces & "|" 
& Episode Name padded out to 15 characters with spaces) which I require 
in my iRecorder app. This amended app (SortCorrespondingArrays) is 
attached. It compiles OK. But it gives a runtime error (Bad Argument in 
Main:42) on line:
Print hEpisode.CompositeKey & Space(19 - Len(CStr(hEpisode.CompositeKey)));

It must be obvious but I don't see the cause. Any ideas?

Also, I would like to only have the option of sorting on CompositeKey. 
What do I need to remove/change to do that?
