CallBack

Optional name of a Callback Function that receives all %WM_COMMAND and %WM_NOTIFY messages for the control.

If a callback for the control is not designated, you must create a dialog Callback Function to process messages from your control.

If the Callback Function processes a message, it should return %TRUE (non-zero) to prevent the message being passed unnecessarily to the dialog callback (if one exists). The dialog callback should also return %TRUE if the notification message is processed by that Callback Function.
