How the Framework Searches Message Maps

|  Overview |  How Do I | 

The framework searches the message-map table for matches with incoming messages. Once you use ClassWizard to write a message-map entry for each message you want a class to handle and to write the corresponding handlers, the framework calls your handlers automatically. The following topics explain message-map searching:

• Where to find message maps

• Derived message maps

• Mapping ranges of messages, command IDs, or control IDs to one handler
