I created an ATL composite control on which I placed the tabctl32.ocx
control. This control fills the entire composite control. To make a long
story short, the control contains several other dialogs and each of the
dialogs has edit boxes, buttons, drop-downs, etc., on them.

I need the tab key to function in the control so that it will move the
user to the next control as it does in normal MFC dialogs; however, this
does not happen.

I found a reference to a method which should perform this functionality
in the Microsoft Systems Journal article "Extending ATL 3.0 Control
Containment to Help You Write Real-world Containers". Their method is to
override "PreTranslateAccelerator" in the composite control class and
iterate through the contained controls with the functionality of the
overridden PreTranslateAccelerator. However, I have determined that my
override of PreTranslateAccelerator is never called.

Is there any means that I may use to get the control to call
PreTranslateAccelerator?

All the best,
Matthew

First, in which container is the control sitting ?
I have found several major bugs with VB6 and the focus/tab management :
( :(

Did you tried to override the GetControlInfo and the
TranslateAccelerator methods ?
Make them return E_NOTIMPL and manage the tab key in a
standard WM_KEYxxx handler. The handler should be under
an alternate MSG map for your CContained<TabCtrl> object.

Did you checked whether the 'TranslateAccelerator' method is
called or not ?

Are you sure that your control has the input focus ? In some cases, it
can be usefull to override the myControl::onsetfocus to make it
explicitly set the focus to the contained control.

Hope it helps
