And what we say generally may or may not have anything to do with how your code is working. That's pretty frustrating for everybody. If a combobox is too complicated to follow it's events, then it's design had probably gotten out of control. It might be that it needs to be an abstract class with some functionality with a concrete class with other functionality.

Think of it as an abstract object and not a specific implementation (a combobox is a specific implementation). Or you could 2) create generic combobox class and gradually add in the functionality you need, carefully testing as you go.

Nancy,

I'm going to post a version of the following in other threads I've started recently as it addresses those issues as well.

The solution to the combobox/focus problem had a lot to do with a very simple thing. As I broke it apart and started doing some research I found a very obvious reason that it wouldn't hold focus. The Enabled was initially set to False and only when it was refreshed would it be set to True and accept the focus. Since it was on a different page, and ThisForm.Refresh will only affect the current active page, the combobox.Enabled was not reset to True until that page was refreshed. This also expains why there was a difference when the form ran the first time as opposed to any subsequent time. It also reacted differently depending on whether ActivePage or SetFocus was called first. By my recent experience, ActivePage should be set first.

Thank you all for your input. I'm afraid I made the problem appear much more complex than it was and in the process throwing you all off the scent...

Bottom line: Make sure an object is Enabled before setting focus to it.
