Parameters

The CATID for the extender being requested.

ExtenderName: String

The name for the extender being requested.

The extendee object.

An extender.

Attributes: DispIdAttribute

Remarks

GetExtender returns the extender for the given CATID and name for the specified extendee instance. This method is called only if CanExtend returns true.

The extender provider must keep ExtenderSite object and Cookie.

Warning

The extender manager maintains an internal cache of extender objects, and must be notified when they are being destroyed. You must call NotifyDelete immediately upon destroying extender objects. You must not wait for the application to become idle, because other Visual Studio components may try to access the destroyed extender object before you call the method. If this happens, Visual Studio may crash.

Note

The extendee object is passed as an IUnknown interface.
