MFC: is it possible to to have view with multiple documents?

Is it possible to associate a view with different documents (not simultaneously of course)? What I want to achieve: the application can have multiple documents of the same type, that can be added during runtime, and set of suitable views, the main of which is CFormview-based. The user can choose the number of the document to show per combobox in the toolbar. The views then associate themselves with this document and update with data from it. Is it possible to achieve with CMultiDocTemplate?

If yes, how? especially is it possible to retrieve a document by it order number?

If not I'll probably have to abstain from using the templates altogether, which of course means more coding (and more questions to friendly community), but it will do what I want it to do and not Microsoft thought I should be doing

Yes, you could but not out of the 'box'. Instead I'd recommend a different strategy. Rather than trying to attach a View to an existing CDocument derived class LOAD the Views CDocument with the information you want. That could done by adding a simple Copy method to the CDocument or you could move your actual data into a separate class then just point the CDocument to 'data' you want.

Trying to change the CDocument instance for a CView is going against the MFC grain which normally means lot of ASSERTS.
