Sending a message to all controls on a form

Question: Is there a way to send a message to all the controls on a form? Answer: You can use Screen.Forms[i].BroadCast(msg); where [i] is the index of the form you wish to broadcast the message to. BroadCast works with all TWinControls components, and sends messages to all children in the Controls array. If one of your children wants to handle the message and have BroadCast exit, then set Msg.Result to a NonZero value during the processing of the message.
