Microsoft scanned this file for viruses. Microsoft used the most current virus-detection software that was available on the date that the file was posted. The file is stored on security-enhanced servers that help to prevent any unauthorized changes to the file.
When multiple instances of the MAZE application are started, MAZE draws a bouncing ball in the client area of one of its instances. MAZE creates a DDE communications link between instances of the MAZE application and uses this link to pass the ball to other instances at random. MAZE also creates a DDE conversation with Excel and passes statistical information about the ball to Excel.

MAZE demonstrates how to use DDE to pass information between applications and how to use PeekMessage to allow other applications to run simultaneously with a process-intensive task.
