[DUG] Large Fonts/DPI

[John Bird]

I have come across something I have not seen before - and I do not
understand the issues involved and what I need do do, so please help!

Background:
I have some forms I resize according to users screen resolution, and also
settable options which font sizes are to be used in grids, and also default
row height.  Both specified in points.  Behaves nicely on most screens

-Except-

Where screen has been set to use large fonts, eg 120DPI, eg Windows 98 with
a large resolution LCD screen.  The fonts I have set in the grid then become
enormous, nothing like 8 pt which is the default and unreadable.  So how do
I detect the DPI setting, what does it mean for my app, and how do I adjust
the font size.....I am able to do that, but unsure what to adjust.

Any advice or web sites?
