CScrollView and mapping modes

Hi,

I have an SDI interface where I use CScrollView. I have read that this 
class sets the mapping mode to MM_ANISOTROPIC. For the past three weeks I 
have been struggling to use MM_LOENGLISH so that the view can be printed. 
My problem is that the columns of text that cover my vertically scrolling 
view spread out differently on every machine that I run it on. Is this 
because I am fighting against inherited behavour or because there is 
something about mapping modes working differently on different graphics 
cards ?

Any suggestions would be great.
I have MSDN.

Phil.

Phil,

You want to set the mapping mode for the device context *differently*
depending upon whether you are drawing to the screen or
printing.  The standard way to do this is to override OnPrepareDC()
in your CView-derived class, and set the mapping mode there by
a call to SetMapMode().

Phil,

        It sounds as if you have a font problem.  A couple of things to
think about:

        1.  Not all fonts are on all machines.

        2.  If the font is not found,  your s/w will select the "best
approximation" of the font you selected.

        3.  Did you set the columns up with tabs or spaces?

        4.  Fixed width fonts work differently than variable width fonts if
you do not use tabbed columns (btw, tabbed columns are the "correct" solution).

        Good luck,

        Jet
