I would use a non-modal dialog that you could start in my mainframe code
(once it is created). You could send messages to the non-modal dialog to
tell it to change messages, percentages, etc. Then you could simply destroy
the dialog when the whole operation is complete. You could also give the
user a chance to cancel on this dialog and just check a flag periodically to
see if a cancel has been requested (or have the dialog send a message to the
mainframe/parent for cancel).

Hi,

I'm working on an application that displays data from a database. It is
implemented with doc/view architecture and each document represents one
record in the database.

Each view gets the database record number from the document and fetches
the data directly from the database on its OnInitialUpdate. I'm using this
code to open new documents:

//pDocument is a pointer to my CDocTemplate
//CMyDocument is my CDocument derived class
//recordNumber is my record number (ULONG)

pDocument=(CMyDocument*)pDocTemplate->CreateNewDocument();
pDocument->Initialize(recordNumber);
pFrameWnd=pDocTemplate->CreateNewFrame(pDocument, NULL);
pFrameWnd->InitialUpdateFrame(pDocument, TRUE);

Since the data can take a few seconds to fetch, I would like to display a
modal dialog box with some progress indicator.

How can I manage to do this? My main problem here is how to display the
dialog *before* the child frame is displayed, but my OnInitialUpdate only
gets called after the InitialUpdateFrame call.

Any ideas?

Thanks,

Pedro Ferreira
