FUNCFLAGS Enumeration


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Identifies the constants that define the properties of a function.

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

Public Enumeration FUNCFLAGS

Member nameDescription

The function that supports data binding.


The function that best represents the object. Only one function in a type can have this attribute.


Permits 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, a call is generated to that member function. Permitted on members in dispinterfaces and interfaces; not permitted on modules.


The function that is displayed to the user as bindable. FUNCFLAG_FBINDABLE must also be set.


The function should not be displayed to the user, although it exists and is bindable.


Mapped as individual bindable properties.


The property appears in an object browser, but not in a properties browser.


Tags the interface as having default behaviors.


When set, any call to a method that sets the property results first in a call to IPropertyNotifySink::OnRequestEdit. The implementation of OnRequestEdit determines if the call is allowed to set the property.


The function should not be accessible from macro languages. This flag is intended for system-level functions or functions that type browsers should not display.


The function returns an object that is a source of events.


The type information member is the default member for display in the user interface.


The function supports GetLastError. If an error occurs during the function, the caller can call GetLastError to retrieve the error code.

The common language runtime throws an exception when a COM method in native code returns an HRESULT. For more information, see How to: Map HRESULTs and Exceptions.
