Constants

 
VARFLAG_FREADONLY
Value: 0x1
Assignment to the variable should not be allowed.
VARFLAG_FSOURCE
Value: 0x2
The variable returns an object that is a source of events.
VARFLAG_FBINDABLE
Value: 0x4
The variable supports data binding.
VARFLAG_FREQUESTEDIT
Value: 0x8
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_FDISPLAYBIND
Value: 0x10
The variable is displayed to the user as bindable. VARFLAG_FBINDABLE must also be set.
VARFLAG_FDEFAULTBIND
Value: 0x20
The variable is the single property that best represents the object. Only one variable in type information can have this attribute.
VARFLAG_FHIDDEN
Value: 0x40
The variable should not be displayed to the user in a browser, although it exists and is bindable.
VARFLAG_FRESTRICTED
Value: 0x80
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_FDEFAULTCOLLELEM
Value: 0x100
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_FUIDEFAULT
Value: 0x200
The variable is the default display in the user interface.
VARFLAG_FNONBROWSABLE
Value: 0x400
The variable appears in an object browser, but not in a properties browser.
VARFLAG_FREPLACEABLE
Value: 0x800
Tags the interface as having default behaviors.
VARFLAG_FIMMEDIATEBIND
Value: 0x1000
The variable is mapped as individual bindable properties.
