Printing a CFormView?

Hello Everyone,

I'm fairly new to MFC programming, but I have been doing a lot
of reading (Inside Visual C++ Version 4 -- Kruglinski) and I
have gotten thru 17 chapters.  I have just finished reading
the chapter on printing and the steps needed to complete this.
However, I am kind of at a loss as how to print controls in
a CFormView to a printer.  As the framework takes care of 
almost everything in this type of view, I assume that something
would need to be overwritten (OnPrint/OnPrepareDC...) but I
wouldn't know what to even do in the OnPrint to "draw" a
control.

As of right now, I have some edit controls placed in a
CFormView and I am sure that would be able to respond to
OnPrint() messages, but how does one "tell" a control
to "draw" itself with the given CDC?  I guess there is
the possibility that I would need to either "translate"
what the controls would look like via simple drawing
commands, or I could possibly try to do a window capture
into a bitmap to be printed.

Any comments or suggestions would be appretiated.

Thanks in advance,
MCI

There is a sample called VIEWEX (in Visual C++ V1.0 only) that demonstrates a
simple technique to print a CFormView.  Basically you navigate all the controls
in the formview and send them a WM_PAINT message in your CFormView::OnPrint 
overide.  The sample was withdrawn in releases after V1.0 because this
technique does not work for all controls but is OK for the edit controls
you have.
