Thanks! I wound up removing the dialog and recreating it and adding the event handler class again. In hindsight I probably could have gotten away with just removing and adding back in the event handler class but I was getting strange errors from the dialog header telling me the the IDC I gave the form was no good. This was a result, evidently, of not having the rest of the #includes in the header.
That compiler errors in C++ really stink. About 50% of the time what they say is useless....grump, grumble...., 45% of the time it is hard to relate what they say to changes you just made in your code, 5% of the time they are dead on....
