Views and Prop Sheets

Hi, 

I`m having some trouble with the following, and I`d 
appreciate any help or reference to some appropriate 
documentation.

I`m attempting to put a CView which displays graphics, 
on the right side of the screen (MDI btw), and a Property
Sheet(a few tabs), which will handle the input, on the 
left side.  Modifying the input in the tabs should modify 
the view on the fly.

I am having trouble :

     1) creating the second (CFormView) window. I created
        a second template with the new CFormView name, 
        and it asks me which view to use at startup !!!

     2) displaying the PropertySheet in a window and 
        not as a pop up.

Am I going about this in the wrong way ? Also :

     3) The graphic output contains some bitmap fills
        which takes time.
        How would I create a transparent window on top 
        this view to allow me to update only one 
        view/window at a time ?


Thanks in advance.

              - Ziv.

My book goes on about this.  I think the FAQ does, too.  You can
take three approaches to have the list of choices not show up:

a) don't register your extra template with MFC.  That is, don't
   call AddTemplate().
b) alter your template's resource string so that it has a blank
   type name
c) override OnFileNew() to explicitly create a document of one
   particular template instead of offering the user a choice.

The SNAPVW sample that's right on the product CD shows how.

I don't understand this question; I don't know what relationship
you're perceiving between transparent windows and updating only one
view at a time.

of course, it's going to ask which one.  when it had only one to choose from,
it was able to figure it out.  I suggest making a CMultiDocTemplate
derivative which you can specify which kind of view to open next.

You need to put a tab control in your mainframe and then use several view
types (one for each page) to have this as a window.
There is an example of this at:
http://www2.vertexgroup.com/mfc-l/
get the tabview.zip example

You may think about having a separated thread that only does the bitmap
fills.
Of course, then there is the synchronization issues.

As another thought.  I had a project that was something similar.  I had one
mainframe window that had several screens (tabs were used) that were editable
data and then one of the tabs was the Finished Data tab.  I did this because
regenerating the data is by definition a lengthy process.  You might want to
think of this approach.
