Hi,
In my doc/view application I need to open text files which can be
quite large. So I would like to display a dialog with a progress bar
and a "Cancel" button.
I more or less know how to create the modeless dialog, how to read the
file in a worker thread, etc. but I'm not quite sure where to create
the dialog. I mean, the logical place seems to be the document
(CMyDocument::OnOpenDocument), since it's the document who reads the
file, but I can't send messages from the worker thread to the document
to update the dialog.
I have tried to handle ID_FILE_OPEN in the view and create the Dialog
in there, but I think it's not the right solution.
So, what would be the right place to create the dialog?
Thanks in Advance
Mikel

Create the dialog in the document, right before you start the thread. You
can pass the dialog pointer or HWND to the thread so it can post progress
messages to the dialog.
