Presenting the user with a graphical representation of the enhancement stream time line enables the user to better visualize where in the stream an event occurs. This can be accomplished, for example, by creating a Microsoft® ActiveX® control that reads an enhancement stream and displays the events in a horizontal time line. The following illustration presents an example of a control that uses arrows to indicate events.
You might write a graphical time line control that enables the user to edit an event by clicking on the marker that represents it.
