I remember something like 'EnableDialogItem'.  But, in a somewhat brief
glance at the toolbox references online, I can't find it.  I'm fairly sure
there's a flag that's settable in the resource, but that's not what we're
looking at here.

The way I remember doing it (and it's been a while), I would set the enable
flag before drawing the dialog box, but I don't remember how it was done.

Wait, I think I found it.  There's a constant, itemDisable, that gets added
to  the item type to disable it.
