Thank you for your answer. I do not believe that the CFont object lifetime is
less than <name>View. A skeleton view of the code is:

Constant.h
  extern CFont obj;
  extern const LOGFONT lf;

Constant.cpp
  CFont obj;
  const LOGFONT lf = {<Courier specification };

main.cpp
CMainFrame::CMainFrame()
{
    // TODO: add member initialization code here
   obj.CreateFontIndirect(&lf); // Font for text output
}

<name>View.h
  class C<name>View : public CScrollView {}

and then when I do:
C<name>View::C<name>View() { SetFont(&obj); }

I get an abort in SetFont() processing. I believe that
  ASSERT(::IsWindow(m_hWnd));
fails in SetFont.

I must be doing something idiotic. I just can't figure out what I'm missing.

SetFont will work. You need to make sure that font object lives as long as
the window itself. Make it a member of the class.Here is a KB article of
using SetFont:

I'm trying to change the font in a Client View in an MDI application
(<name>View.cpp) and am having trouble. I used SetFonts(LOGFONT* lf) with
Courier and it didn't work. Any idea how to do the nasty deed?

Details: The project contains <name>Doc & <name>View. I and using the
Client
Window controlled by <name>View as a logging output window. The current
font
is a variable font type (system font I suppose) and I'm trying to change
it
to a fixed font (Courier). I have used 'EnumFontFamiliesEx' to get the
LOGFONT structure for Courier and <name>View.SetFont() to change the font.
Doesn't work.
