Logical and Physical Views

Value	Description
LOGVIEWID_Code	GUID_VSStandardCommandSet97cmdidOpenWith handlers should pass this value to the OpenStandardEditor method to get the Open With dialog box, in this case on possible Code views.
LOGVIEWID_Debugging	GUID_VSStandardCommandSet97cmdidOpenWith handlers pass this value to the OpenStandardEditor method to get the Open With dialog box, in this case populated with possible LOGVIEWID_Debugging debugging views which map to the same view as LOGVIEWID_Code.
LOGVIEWID_Designer	GUID_VSStandardCommandSet97cmdidOpenWith handlers pass this value to the OpenStandardEditor method to get the Open With dialog box, in this case to View Form designer views.
LOGVIEWID_Primary	GUID_VSStandardCommandSet97cmdidOpenWith handlers pass this value to the OpenStandardEditor method to get the Open With dialog box, in this case the default/primary view of the editor factory.
LOGVIEWID_TextView	GUID_VSStandardCommandSet97cmdidOpenWith handlers pass this value to the OpenStandardEditor method to get the Open With dialog box, in this for a document or data text editor view.
LOGVIEWID_UserChooseView	GUID_VSStandardCommandSet97cmdidOpenWith handlers pass this value to the OpenStandardEditor method which prompts the user to choose which user-defined view to use.

Editor Factory Flags

Value	Description
CEF_CLONEFILE	An obsolete flag combined bitwise as the first parameter of the CreateEditorInstance method.
CEF_OPENASNEW	Combined bitwise as the first parameter of the CreateEditorInstance, method, this indicates the editor factory should perform necessary fixes.
CEF_OPENFILE	Combined bitwise as the first parameter of the CreateEditorInstance method, this flag is mutually exclusive of CEF_CLONEFILE.
CEF_SILENT	Combined bitwise as the first parameter of the CreateEditorInstance method, this indicates the editor factory should create the editor without displaying a user interface (UI).
