The C# example you obtained in the other message is a replica of my data class, but at a high level only. That would be the way to follow. It is just that I have thousands of lines in mine which handles pretty much anything you could imagine in regards to a data class. It took me a while to build it. But, it was worth it at the end.

As for the Hungarian reference, it is just a naming convention. The goal is to have one. I really do not care which one people uses as long as they have one I think this is good. This is what I teach. I wouldn't touch any code if there wouldn't be any convention in it. It would be a total waste of time. In such a case, people involved might as well start from scratch. Mine is dated from the earlier '90s from a class I took from Yair Alan Griver. This is kind of a reverse hungarian notification. I apply it to everything. It was first used in VFP, then in .NET and javascript. At least, when I see loConnection, I know it is a local variable of type object about the Connection namespace. As simple as it gets, cFirsName would then be a public property of type string for the first name. I have seen so many examples on the net with For i =.... Wow, when I see it down below the code, I say to myself what the heck is i for. But, if I see For lnCounter=... Then, down below the code, if I see a reference to it, I know it is a local variable of type integer for a counter. In VFP, most of the developers had a good naming convention. When I started to move to .NET, I saw that most of that disappeared in space and it was sad.
