There's one big problem with CallByName - it trashes the Error information.
I was trying to implement a Properties() method for my classes without
resorting to a large Select Case statement, and CallByName seemed like a
perfect solution until I found out that any errors occuring would not
provide normal error information, but only one of the generic
'Application-defined' or 'Automation' errors (I can't remember which). MS
has a KB article about this saying it is 'By Design' which means they're
either too lazy or too incompetent to fix it. The more I use VB, the more I
realize that the developers at MS who write it don't actually use it, or
else they'd fix a lot more of these annoying little problems.
