'使用
Dim instance As Source
Dim riidKey As Guid

public virtual void OnUserDataChange(
    ref Guid riidKey,
    Object vtNewValue
)

public:
virtual void OnUserDataChange(
    Guid% riidKey, 
    Object^ vtNewValue
)

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.
