DDE is a code sample in the Microsoft Software library that demonstrates dynamic-data exchange (DDE) and how it is programmed under Windows 3.0.

Download DDE.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 DDE.EXE (size: 33939 bytes)
  • Internet (anonymous FTP) 

          ftp ftp.microsoft.com
      Change to the \SOFTLIB\MSLFILES directory
      Get DDE.EXE (size: 33939 bytes)

There are two separate applications in the DDE archive file: TICTAPE and BARGRAPH. For each application, the archive holds a makefile, header file, C source code, resources (.RC) file, segment definitions (.DEF) file, and an icon.

TICTAPE is a DDE server that randomly creates and transmits data about four stocks. BARGRAPH is a DDE client that graphically illustrates the data from TICTAPE. TICTAPE was demonstrated at "Windows on Wall Street," June 4, 1986.

To use these applications, perform the following six steps:

  1. Download from the Microsoft Software Library and expand the DDE file.

  2. Build TICTAPE and BARGRAPH.

  3. Start Windows.

  4. Run TICTAPE.EXE.

  5. Run BARGRAPH.EXE.

  6. Activate TICTAPE and choose "Start Ticker Tape".

The BARGRAPH application's main window will dynamically display the (random) values of the four stocks.

Additional information concerning DDE can be found in Chapter 22 of the "Microsoft Windows Software Development Kit Guide to Programming" and in Chapter 15 of the "Microsoft Windows Software Development Kit Reference, Volume 2."
