BEGIN_TEMPLATE_MESSAGE_MAP
Visual Studio 2008
Begins the definition of a message map on a class type containing a single template argument.
BEGIN_TEMPLATE_MESSAGE_MAP(theClass, type_name, baseClass )
This macro is similar to the BEGIN_MESSAGE_MAP macro; however, this macro is intended for classes containing a single template argument.
In the method implementation section of your class, start the message map with the BEGIN_TEMPLATE_MESSAGE_MAP macro; then add macro entries for each of your message-handler methods as you would for a standard message map. As with the BEGIN_MESSAGE_MAP macro, complete the template message map with the END_MESSAGE_MAP macro.
