System.Runtime.InteropServices.ComTypes.VARFLAGS Enumeration

Identifies the constants that define the properties of a variable.

Syntax

[System.Flags]
public enum VARFLAGS

Remarks

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.

Members

Member NameDescription
VARFLAG_FBINDABLE

The variable supports data binding.

VARFLAG_FDEFAULTBIND

The variable is the single property that best represents the object. Only one variable in type information can have this attribute.

VARFLAG_FDEFAULTCOLLELEM

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

VARFLAG_FDISPLAYBIND

The variable is displayed to the user as bindable. System.Runtime.InteropServices.VARFLAGS.VARFLAG_FBINDABLE must also be set.

VARFLAG_FHIDDEN

The variable should not be displayed to the user in a browser, although it exists and is bindable.

VARFLAG_FIMMEDIATEBIND

The variable is mapped as individual bindable properties.

VARFLAG_FNONBROWSABLE

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

VARFLAG_FREADONLY

Assignment to the variable should not be allowed.

VARFLAG_FREPLACEABLE

Tags the interface as having default behaviors.

VARFLAG_FREQUESTEDIT

When 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_FRESTRICTED

The 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_FSOURCE

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

VARFLAG_FUIDEFAULT

The variable is the default display in the user interface.
