George,

That's good stuff. Thanks for sharing it...

By adding an _Assign method to each property, I was easily able to validate the incoming information. If the information was valid, I set a bit of an integer property to indicate that the data was valid. If it was invalid, I made sure that the bit was cleared. Each property was thus represented by a bit. Using BITAND() allowed me to easily test to make sure that all the necessary properties were properly initialized.
