Supported by Portable Class LibrarySupported in .NET for Windows Store appsVARFLAG_FDEFAULTCOLLELEMPermits an optimization in which the compiler looks for a member named "xyz" on the type of "abc". If such a member is found and is flagged as an accessor function for an element of the default collection, then a call is generated to that member function. Permitted on members in dispinterfaces and interfaces; not permitted on modules.
Supported by Portable Class LibrarySupported in .NET for Windows Store appsVARFLAG_FDISPLAYBINDThe variable is displayed to the user as bindable. VARFLAG_FBINDABLE must also be set.

Supported by Portable Class LibrarySupported in .NET for Windows Store appsVARFLAG_FREQUESTEDITWhen set, any attempt to directly change the property results in a call to IPropertyNotifySink::OnRequestEdit. The implementation of OnRequestEdit determines if the change is accepted.
Supported by Portable Class LibrarySupported in .NET for Windows Store appsVARFLAG_FRESTRICTEDThe variable should not be accessible from macro languages. This flag is intended for system-level variables or variables that you do not want type browsers to display.
