Re: CreateNewFrame
Yes, I'm pretty sure that's how it works if you use and existing doc from
another window. You could create a new one of course using the same document
object and preinitialize it any way you want from an existing one then pass
in the new one. It uses the doc pointer to associate the document with the
frame window so other windows (like views for example) know what document to
use for getting the data to display.
I'm not sure about the NULL objects being passed in. I know the "Other"
object can be null and it just puts out a Trace statement, but I'm not sure
how a frame with a view would work without a document as well.
I mostly let the framework create these windows for me so I'm not really an
expert on how it works internally. You could just fish the document out
from one of your views and see if it points to the same object as the
original one then you would know for sure.

Thank you.
We indicate what type of doc, view, frame it will use whe writing
CMultiDocTemplate. Right? Why does it need another pDoc pointer. I assumed
it
uses it for initializing.
If it uses same pointer when i pass a CDoc pointer... does it mean that it
doesn't create a new doc object.
Interesting, yes, i passed NULL pointer and program gave run-time error.
But
why does MSDN write this:
"pDoc
The document to which the new frame window should refer. Can be NULL."
If it doen't create a new Document object, Mustn't it write "Can't be
NULL"
instead of "Can be NULL" ?

Hi
I have a simple question about CreateNewFrame:
virtual CFrameWnd* CreateNewFrame(
CDocument* pDoc,
CFrameWnd* pOther
);
If we pass a Document pointer to that function like that:
pDocument = pActiveChild->GetActiveDocument()
CFrameWnd* pFrame = pTemplate->CreateNewFrame(pDocument, NULL);
I copies all the values of variables from pActiveChild's document
object
to
new document.
If we pass NULL, it makes empty variables.
Is that right?
