I have some code that creates a property sheet and some property pages:

I am on Windows 7 and am using the latest version of Visual C++ 2017 (15.9.2).
I have a derivative of PropertySheetBase and 3 derivatives of PropertyPageBase. In the PropertySheetBase derivative constructor I call Add_Page to add the 3 property pages to my sheet then later I call ShowDialog to actually display the property sheet and
its pages.
However, only the first page is showing up, the other 2 tabs dont appear. Can anyone see anything wrong with my code in terms of how I use property sheets and property pages and anything I should do differently to make the other tabs appear? (it doesn't
help that the MSDN documentation for property sheets and pages isn't exactly the best quality and some things are either not documented or not easy to find)
If you need to see the code that's actually using these classes, I can share the relavent components.
