Use this macro to map a contiguous range of control IDs to a single message handler function for a specified Windows notification message, such as BN_CLICKED.
The notification code to which your handler is responding.
Command ID at the beginning of a contiguous range of control IDs.
Command ID at the end of a contiguous range of control IDs.
The name of the message-handler function to which the controls are mapped.
The range of IDs starts with id1 and ends with id2. The handler is called for the specified notification coming from any of the mapped controls.
There is no automatic support for message map ranges, so you must place the macro yourself.
