Is it possible to nest CExtTabPageContainerWnd class objects?

I have created a property-sheet-like dialogue using a CExtTabPageContainerWnd container for several child pages, as in your test_page_sheet example. This works well.

I want to create two grandchild pages within one of the dialogue child pages.

I experimented with creating a second CExtTabPageContainerWnd container (with different ID) in the child page, and inserting two grandchild pages into it with tabs at the bottom rather than the top of the page.

All works well except that the nested tab buttons are not responsive. I’ve not succeeded in detecting messages using Spy++ either.

My mistake.

I created the offending parent page as a property page (IDD_PROPPAGE_LARGE) in the resource editor and then changed the border and clipping styles. I didn’t notice that the page was therefore also created with a Disabled style.

The nested CExtTabPageContainerWnd objects work fine now that that is fixed.
