The child ID notification message macros provide a number of different ways to handle child ID notification messages.

You can handle notification codes from multiple children with a single function, pass all notification codes from a child to a response window, or handle the notification code at the child. You use these macros to facilitate controlling and communicating with child controls. The different types of child ID notification message macros are listed in the following table:
