Ah-ha. So if I use PropertySheetDialog, I can't add any controls to the main window. Is that correct?

Yes, basically.  You can configure the PropertySheetDialog to have an 'Apply' and a 'Help' button also.
 
I just tried deleting the OK button from the .rc file, and nothing changed when I ran PropertySheetDemo.rex. So I guess that OK and Cancel are provided automatically. 

There is no dialog template for the PropertySheetDialog in the .rc file.  The .rc file is shared between the PropertySheetDemo and the TabDemo examples  If you delete the button from the .rc file and run the TabDemo example, you will see no Ok button.

The IDD_NEWCONTROLS_DLG template in the .rc file is *only* used by the TabDemo example.
 
 
I also notice that there's no code at all for the main window other than the ::class statement.

Yes.  For the most part it is not needed.

I have said this so many times, that I think I dream it in my sleep.  ;-)    But, it is very key to understanding how to use a PropertySheetDialog dialog.

PropertySheetDialog dialogs are unlike any other dialog in ooDialog.  A PropertySheetDialog is managed completely by the Operating System.  All other ooDialog dialogs are managed completely by the ooDialog framework.

I think the implications of this probably are not as readily evident to the ooDialog programmer as they are to me.  You can not connect any events for the PropertySheetDialog dialog.  There is no way for ooDialog to intercept those events.  The notifications are sent to the operating system.  You connect the events of the property sheet *page* dialogs.

There is no Ok or Cancel method for the PropertySheetDialog dialog.  You control closing, or preventing the closing, through the event notifications of the *page* dialogs.
 
 
So if I were to say that, for PropertySheetDialogs, the programmer has no control whatsoever over the content of the main window, and that the main window will and can only contain the property sheets plus an OK and Cancel button plus optionally a menu, would that be correct?

Mostly, but not entirely.  As I said you can optionally have the Apply and Help buttons.  The Apply button is actually more standard.  So, it is probably more correct to say the Apply button is optionally removed from the PropertySheetDemo.  That was done to make the dialog look like the old propdemo.rex example.

I don't know that you can add a menu, you probably can't.  It is possible to add a menu to the underlying PropertySheet window, but not recommended by Microsoft.  It takes some special hooks and I don't recall that I added them.  If there was some demand for that functionality, I could look into it, to see if it is possible in ooDialog.  But, I don't currently have any plans to do it.
