Re: How to switch the document within CMultiDocTemplate instance?

Tech-Archive recommends: Fix windows errors by optimizing your registry

This seems very odd.

First, it sounds like you are using a CFormView. In that case, "replacing" the controls
consists of simply enabling/disabling or showing/hiding some controls.

Switching the document out from under the running view seems a bizarre thing to want to
do. Switching the template so future documents may be created differently is already a bit
strange, but perhaps it makes sense. But switching the actual document representation
underneat a view is an invitation to disaster. I don't even want to THINK about what
happens with virtual methods in this case, but It Will Not Be A Pretty Sight.

You really need to explain a lot more clearly what you want to accomplish. You are
probably approaching the problem from the wrong viewpoint. The safe thing to assume is
that you do NOT want to change the document type of an actual document, and from your
description it sounds more like you are wanting to change the view.

You probably have a simple problem which you are making a hard problem, but this
explanation is not much more enlightening.But since you say you are new at this, my
suspicion is that this is almost certainly the wrong approach for whatever you are trying
to accomlish.
