Well, if you're familiar with CW_PDMENU, you know you don't
want to use that. :-)
And a droplist won't help you, obviously. (A less stilted
form of "of course". What do you think?)
So I think the only course left to you is to build
your own pull-down menus from buttons. Here is an
example that doesn't do anything useful, except allow
you to see which choices are turned ON and which are
turned OFF.
Cheers,
David
