Thanks Arjay. I appreciate your efforts and time spent. You have created a Doc/View project in Visual Studio 2005, which successfully permits writing of data from Doc/View to a dialog called from a menu item. This is what I have already achieved in VC++6.
Unfortunately I cannot figure out what I should do either in VC++6 nor in the VS2005 example you sent in order to be able to transfer data to a CListBox. It has to be a listbox, since the entries are generated at runtime from random filesets, and the entry count can be between 1 and 100 or so, and the user must select which ones he wants converted and simultaneously displayed.
Eugene Kain in his modestly titled book shows how one can communicate between a Dialog and a Doc/View, but cleverly avoids anything other than trivial items. No guesses for what I'd like to do with his fat tome.
I'm beginning to think that what I'm trying to do is impossible.
