Alright, what am I missing? Print Report

[Zwired1]

Troubleshooting a printer problem today, I had occasion to open the front panel of "Print Report.vi" (report generation toolkit).  There's nothing there!  Both the "error" and "no error" cases just pass the report ref through without operating on it, calling a DLL, etc.   So....how does it get the data to the printer?

It's part of a LVOOP class.  You're looking at the VI for the parent class, but the wire will always carry a child class (HTML, Word, Excel, etc).  The Print Report member of the child class is the one that will be executed - overriding the parent - and it contains the actual code.

Ah. Thanks. Been ignoring OOP 'cause I've never found a case where I could be more effecient/effective using it.  Guess I should at least get the fundamentals. Argggh.
