I'd post again in an MFC group to find out what your option are.
At the level of the API you can call GetOpenFileName() and specify a hook
procedure. The hook procedure should (I've never tried) allow you to enable
and disable controls on the dialog. Read the docs for the description of the
OFNHookProcOldStyle() function that you'll have to develop. Note carefully
the restrictions and the distinction between old-style and Explorer style
hooks.
