A more complex type of control frame application, the read/write application provides concurrent frames that let end users enter data in some frames and select data in other frames. For this type of application, you use the openframe statement to open each of the concurrent frames from the parent frame.

An application of this type is more difficult to develop because you must ensure that any changes in the child frames are reflected in the parent frame. One way to do this is to use the SendUserEvent method and a UserEvent event block to communicate between the frames.

For more information about communicating between frames, see the Programming Guide:
