TYPEFLAGS Enumeration

Defines the properties and attributes of a type description.

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

Namespace:  System.Runtime.InteropServices.ComTypes
Assembly:  mscorlib (in mscorlib.dll)

public enum TYPEFLAGS

Member nameDescription
TYPEFLAG_FAPPOBJECTA type description that describes an Application object.
TYPEFLAG_FCANCREATEInstances of the type can be created by ITypeInfo::CreateInstance.
TYPEFLAG_FLICENSEDThe type is licensed.
TYPEFLAG_FPREDECLIDThe type is predefined. The client application should automatically create a single instance of the object that has this attribute. The name of the variable that points to the object is the same as the class name of the object.
TYPEFLAG_FHIDDENThe type should not be displayed to browsers.
TYPEFLAG_FCONTROLThe type is a control from which other types will be derived and should not be displayed to users.
TYPEFLAG_FDUALThe interface supplies both IDispatch and VTBL binding.
TYPEFLAG_FNONEXTENSIBLEThe interface cannot add members at run time.
TYPEFLAG_FOLEAUTOMATIONThe types used in the interface are fully compatible with Automation, including VTBL binding support. Setting dual on an interface sets both this flag and the TYPEFLAG_FDUAL. This flag is not allowed on dispinterfaces.
TYPEFLAG_FRESTRICTEDShould not be accessible from macro languages. This flag is intended for system-level types or types that type browsers should not display.
TYPEFLAG_FAGGREGATABLEThe class supports aggregation.
TYPEFLAG_FREPLACEABLEThe object supports IConnectionPointWithDefault, and has default behaviors.
TYPEFLAG_FDISPATCHABLEIndicates that the interface derives from IDispatch, either directly or indirectly. This flag is computed; there is no Object Description Language for the flag.
TYPEFLAG_FREVERSEBINDIndicates base interfaces should be checked for name resolution before checking children, which is the reverse of the default behavior.
TYPEFLAG_FPROXYIndicates that the interface will be using a proxy/stub dynamic link library. This flag specifies that the type library proxy should not be unregistered when the type library is unregistered.

For additional information about TYPEFLAGS, see the MSDN Library.

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.
