>Ahh, the problems of multiple controls. I use the MS Monthview control that does have the 3 properties exposed at the control level and the Values property at the .Object level. I should have been more specific. Thanks.

Mark,

The Monthview is OK, but really rather inappropriate for this project. That's why I'm using the Calendar.

Basically, the circumstances that cause this (for any lurkers) occurs when the user selects a month or year from one of the combo boxes. What happens is that the .Value, .Month, .Day, and .Year properties are all set to empty. If you do not set the .Value property first, the others won't take. Rather disconcerting to be stepping through the code in the Trace window, seeing the a variable with a valid value, assigned to one of these properties and then see them unchanged. I understand why this happens, just wasn't aware that it did.
