A button in a CDialogBar object is disabled automatically if the command routing does not contain a command handler function for the button.

To enable a button in a CDialogBar object, the command routing must include a command handler for the button. A button command handler can be an ON_BN_CLICKED(), ON_COMMAND(), or ON_COMMAND_UI() message handler and it must appear in the message map of an object in the command routing. If the parent of the CDialogBar object is a CFrameWnd object, then the command is handled by the active child window or view, by the document attached to the view, by the frame window, and by the application (CWinApp object).

NOTE: Because the CDialogBar object is not included in the routing scheme, the ON_BN_CLICKED() or ON_COMMAND() handler must be placed in one of the objects mentioned above that is in the routing scheme and not in the CDialogBar class.

For more information on command routing, see the "Command Routing" section in Chapter 3 of the "Class Library Reference" manual. In Visual C++ 32-bit Edition, version 4.0, see both the "Command Routing" topic of the "Programming with MFC: Overview" in the Books Online and the MFC Technical Note 31, Control Bars.
