public virtual void OnUserDataChange(
ref Guid riidKey,
Object vtNewValue
)
public:
virtual void OnUserDataChange(
Guid% riidKey,
Object^ vtNewValue
)
abstract OnUserDataChange :
riidKey:Guid byref *
vtNewValue:Object -> unit
override OnUserDataChange :
riidKey:Guid byref *
vtNewValue:Object -> unit
public function OnUserDataChange(
riidKey : Guid,
vtNewValue : Object
)
Parameters
- riidKey
Type: System.Guid%
The GUID representing the value that was changed.
- vtNewValue
Type: System.Object
A Variant containing the new value.
Implements
IVsUserDataEvents.OnUserDataChange(Guid%, Object)
Remarks
A text buffer can have a number of user-settable values associated with it. Each value is identified by a unique GUID. Whenever one of these values is changed with a call to the SetData method in the IVsUserData interface, the OnUserDataChange method is called.
The base method does nothing.
