CXTPCustomizeSheet and Multiple MDI Document Types

Hi there,

I am continuing the evaluation of ToolKit Pro 13.1 to replace RogueWave's Objective Toolkit and have made a lot of progress.

However I have another question/problem with regard to CXTPCustomizeSheet and MDI document commands.

We have a number of MDI document types, and I am looking to add each document type's set of commands (that is, menus) to the customise pages.  However, when I use the AddCategories(resourceID) method on the command and keyboard pages, I wind up with duplicate commands (for example, File->Open...), which is not very helpful.  My question therefore is:

1) Am I missing something on how to prevent duplicate commands being added to the customise pages (command and keyboard pages)?  I have fiddled with the MDITabWindow sample but cannot get it to not add duplicate command entries, and I don't see any sample that makes two AddCategories() calls to say the command page;

2) Given that it isn't currently possible to prevent duplicates with the existing ToolKit Pro 13.1, would I be correct in assuming I would need to derive from the CXTPCustomizeCommandsPage and CXTPCustomizeKeyboardPage classes, and cull out the duplicate CXTPControl entries before display?

Thanks in advance.

Cheers,
Graham
