Each COleControl-derived class in your program can provide a connection map to specify connection points that your control will support.
BEGIN_CONNECTION_MAP(theClass, theBase )
- Specifies the name of the control class whose connection map this is.
- Specifies the name of the base class of theClass.
In the implementation (.CPP) file that defines the member functions for your class, start the connection map with the BEGIN_CONNECTION_MAP macro, then add macro entries for each of your connection points using the CONNECTION_PART macro. Finally, complete the connection map with the END_CONNECTION_MAP macro.
