In Win32.hlp, see "Explorer-Style Control Identifiers" for the ID.
Look under "Combo Box Messages" for things you can do to the ComboBox.

The rest of this is guessing.

To read the SELECTED list value:
	You start with CB_GETCURSEL to get an index
	Then CB_GETLBTEXTLEN to find out how big it is
	Then CB_GETLBTEXT

To read the EDIT portion:
	WM_GETTEXTLENGTH
	WM_GETTEXT

Use SendMessage() for these, and check the return values.

It's easier if the dialog is in your own app, just check the values
returned in the OPENFILENAME structure.
