CContainedWindowT::m_dwMsgMapID
Holds the identifier of the message map currently being used for the contained window.
DWORD m_dwMsgMapID;
Remarks
This message map must be declared in the containing object.
The default message map, declared with BEGIN_MSG_MAP, is always identified by zero. An alternate message map, declared with ALT_MSG_MAP(msgMapID), is identified by msgMapID.
m_dwMsgMapID is first initialized by the constructor and can be changed by calling SwitchMessageMap. For an example, see the CContainedWindowT Overview.
