When I do my resizing, I created a routine that includes (as an option)
the design size screen resolution, and then get the current screen
resolution to create scaling factors for all of the controls. These are
applied to the fonts, as well.

Now, when I 'down sized' below design resolution, it looked rather poor
(granularity of font sizes as they get smaller?). The best you can do
is test for the current resolution and have a separate set of font sizes
that can work with this (these) reduced resolutions.

These days, I design at 800x600 - and it's rare, indeed, that someone's
unit is set to a lower resolution then that. Somewhere in the MSDN,
they actually do suggest one design at low screen resolution (not taking
into account that extreme inconvenience of trying to work with a low
resolution screen). My way of handling this is sizing the dialog box to
screen units from a 'low res' prototype size, and sizing controls and
fonts to fit - later, when scaled upwards, everything's in good shape.

One last caveat: I generally force dialogs to full-screen size in
OnInitDlg().
