# Simple Frame Site Containment

A container control is an ActiveX Control that is capable of containing other controls. A group box that contains a collection of radio buttons is an example of a container control. Container controls should set the OLEMISC_SIMPLEFRAME status bit, and should call its container’s ISimpleFrameSite implementation. An ActiveX Control container that supports Container Controls must implement ISimpleFrameSite.
