I've got 2 problems right now.
1. I'm trying to figure out how to catch the CBN_SELCHANGE or CB_SETCURSEL message, but I'm not having any luck. What message goes to the combobox procedure when the selection is changed?
2. Doesn't the combobox control have the ability to scroll vertically if it needs to? MSDN implies that it can in the description for CBS_DISABLENOSCROLL .
