' NONCLIENTMETRICS like the the window title font,
' the message font,menu font using VB. You can also change
' other elements like status font etc
' in your window only or all the open windows
' like PLUS! or display settings (appearance)
' also it is possible to underline, strikethru fonts in
' your window with this code. This code is very useful
' if you are coding a multi-lingual software.
