Well, since a dialog box is just a parent window with a bunch of children,
you can use EnumChildWindows to get the children of the dialog box (all the
controlls), then query each of the children in turn.  Once you know the
type of field, you can do special work depending on that field (such as,
an EDIT can be quite large, and you might use EM_GETHANDLE to get the contents).
