Description
Instantiates a connection point object.
Create is called automatically by the connection point container's CreateConnectionPoint method to instantiate a connection point object. This occurs when an ActiveX control is initialized.
Create allocates memory for a connection point object and calls the inherited Create, passing it the Container's controlling IUnknown. Container is a connection point container object. Create adds the connection point object to the Container. Then it sets the:
- IID as the GUID or interface identifier of the outgoing interface managed by this connection point.
- IKind, indicating whether it is a single or multiple connection to that point.
- OnConnect as the connection event used in the IConnectionPoint Advise method.
TConnectEvent points to a procedure for the OnConnect event of the connection point. TConnectionKind is a type indicating whether there are multiple connections to the connection point.
