Quick activates the contained control.
Nonzero if the control site was activated, otherwise zero.
This function should be called only if the user is overriding the creation process of the control.
The IPersist*::Load and IPersist*::InitNew methods should be called after quick activation occurs. The control should establish its connections to the container's sinks during quick activation. However, these connections are not live until IPersist*::Load or IPersist*::InitNew has been called.
