Order of: OnActivateView, OnInitialUpdate

Configuration: VisC++ 4.0, MFC 4.0, Win95, MSDN Jan '96, MDI application

I have written a CView subclass which performs some initialization in
OnInitialUpdate.
This initialization code _must_ take place _before_ OnActivateView.

Not a problem right? The calling order is:

When a view is created MFC calls OnInitialUpdate and _then_ calls OnActivateView

BUT when I put my view in a CSplitterWnd, the order is _reversed_

MFC calls OnActivateView _before_ OnInitialUpdate BLOWING up my code.

why, Why, WHY do they switch the order. I am going to _hate_ having to write
special handling code for the case where the view is in a SplitterWnd.

I may be able to move the initialization back into OnCreate, but thats
really too early...

Thanks for any illumination,

Jeff

Hmm - why? (If it can be explained simple?) The only thing
OnActivateView does is conditionally calling SetFocus().

Could you just add a m_bAfterInitialUpdate variable?  Then just ignore
any OnActivateView before OnInitialUpdate and call SetFocus() if your
OnInitialUpdate()?
