Summary: Do it yourself, if needed

Hilighting the default button in an alert box is automatically done
for you if the button is the first item in the DITL list.

To hilight a default button in a Dialog box, you will have to do the
hilighting yourself.  The simplest way is to use GetDItem (...) to
get the Rect that the button is positioned at; InSet that rect about
negative 5 (-5) pixels (that actually makes it larger); set the pen
width to 3 pixels and draw a roundRect.  This will draw the heavy border
around the button.  Reset the pen width and the box, and you're done.

A few points:  make the DLOG invisible in the resource and put the 
hilighting routine immediately after the call to retrieve the DLOG.
Then use ShowWindow to draw the dialog before calling ModalDialog.
Otherwise, the drawing of the hilighting will be out of sync with
the appearing of the window.

Also: unless this is for your own use only, please make the default
button be the least disasterous option to data already saved unless
the dialog is confirmation for updating saved data.

I'm sorry I don't have actual code segments here at work.  If you
have problems and need help, email to me at the address below.
