VARFLAGS Enumeration

VARFLAGS Enumeration

Identifies the constants that define the properties of a variable.

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 VARFLAGS : short
/** @attribute SerializableAttribute() */ 
/** @attribute FlagsAttribute() */ 
public enum VARFLAGS
public enum VARFLAGS

 Member nameDescription
VARFLAG_FBINDABLEThe variable supports data binding. 
VARFLAG_FDEFAULTBINDThe variable is the single property that best represents the object. Only one variable in type information can have this attribute. 
VARFLAG_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. 
VARFLAG_FDISPLAYBINDThe variable is displayed to the user as bindable. VARFLAG_FBINDABLE must also be set. 
VARFLAG_FHIDDENThe variable should not be displayed to the user in a browser, although it exists and is bindable. 
VARFLAG_FIMMEDIATEBINDThe variable is mapped as individual bindable properties. 
VARFLAG_FNONBROWSABLEThe variable appears in an object browser, but not in a properties browser. 
VARFLAG_FREADONLYAssignment to the variable should not be allowed. 
VARFLAG_FREPLACEABLETags the interface as having default behaviors. 
VARFLAG_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. 
VARFLAG_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. 
VARFLAG_FSOURCEThe variable returns an object that is a source of events. 
VARFLAG_FUIDEFAULTThe variable is the default display in the user interface. 

For additional information about VARFLAGS, 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.
