I'm using Visual C++ version 5 and I wish to edit the file extension options shown in the standard FileOpen dialog (that appear on the OnFileOPen Commard) so that there is a list of different file extension, but they appears to be no help on the CWinApp:
oPromptFileName operation. Can you point me in the right place to find out how to change this list? Do I need a different document template for each file type even if they a handle in the same way once opened?
