SUMMARY

MAZE is a file in the Microsoft Software Library that contains the source code to an application that demonstrates how to use dynamic data exchange (DDE) in a Windows-based application.

Download MAZE.EXE, a self-extracting file, from the Microsoft Software Library (MSL) on the following services:

  • Microsoft Download Service (MSDL) 

          Dial (206) 936-6735 to connect to MSDL
      Download MAZE.EXE (size: 27151 bytes)
  • Internet (anonymous FTP) 

          ftp ftp.microsoft.com
      Change to the \SOFTLIB\MSLFILES directory
      Get MAZE.EXE (size: 27151 bytes)

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.
