Marks the beginning of the DHTML event map when placed in the source file for the class identified by className.
Add a DHTML event map to your class to provide information to CDHtmlDialog that can be used to route events fired by HTML elements or ActiveX controls in a web page to handler functions in your class.
Place the BEGIN_DHTML_EVENT_MAP macro in the class's implementation (.cpp) file followed by DHTML_EVENT macros for the events the class is to handle (for example, DHTML_EVENT_ONMOUSEOVER for mouseover events). Use the END_DHTML_EVENT_MAP macro to mark the end of the event map. These macros implement the following function:
virtual const DHtmlEventMapEntry* GetDHtmlEventMap();
