Enter/Leave events firing unexpectedly. Help!

[geneb]

I've got a number of tabs with text boxes on them. When you hit the
last textbox on a tab, it checks to see if the next tab is a valid
destination, then goes to it if so.

Unfortunately, when this happens, both the Enter _and_ Leave events of
the first textbox control are fired, causing all sorts of mayhem.

On a related note, I have another textbox that has it's Enter/Leave
events fired when other controls are changing focus programatically.
The controls changing focus are not text controls.

For example, if control A sets the focus to control B, and B sets the
focus to control D, and D sets to E, the Enter and Leave events of the
textbox will fire each time the focus changes. This happens even
though the textbox never has its .Focus() method called.

This is slowly driving me out of my mind.


Any ideas on how I can prevent this from ocurring? I'm using VS2K3.

Thanks!

Here is further information for anyone that can assist.

This is the call stack showing what occurs from the point I press enter on
one control to the Leave event firing on the control I'm _going_ to.

The control sequence is txtbox -> dimAx -> dimAx -> txtbox.

The dimAx control automatically passes focus to the next control in line if
no input is allowed for it. I'm wondering if this control is causing all the
problems? It's a VB6 ActiveX control.

tnx!
