Public Function OnFileOpenUI( _
   ByRef Filename As String, _
   ByRef AppendToTitle As String _
) As HResult

If you do not want to handle this event, return E_NOTIMPL so that Solid Edge proceeds as if no application was listening to the event and displays its dialog box. If you want to cancel the command, return S_OK (or S_FALSE) while returning all the strings as NULL strings so that Solid Edge proceeds to cancel the command without displaying its dialog box. If you return any other error, Solid Edge aborts the command just as it does when an error is received from one of its methods. If you return S_OK with valid output strings, Solid Edge proceeds to use the strings accordingly
