SUMMARY

TALK is a sample application in the Microsoft Software Library that demonstrates how to share data between two applications without having to use dynamic data exchange (DDE). TALK contains two applications (POST and HELLO) that demonstrate three different ways to pass information between two applications. Please note that either the GMEM_DDESHARE or the GMEM_NOTBANKED flag must be specified when the memory is allocated. This ensures that the memory referenced by the handle is available even when Windows is running in real mode and EMS memory is in use.

Download TALK.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 TALK.EXE (size: 26268 bytes)
  • Internet (anonymous FTP) 

          ftp ftp.microsoft.com
      Change to the \SOFTLIB\MSLFILES directory
      Get TALK.EXE (size: 26268 bytes)

NOTE: Although the principles of message-based DDE communication shown in the TALK sample are compatible with Windows 3.1, Microsoft strongly recommends that new applications for Windows 3.1 and later use the DDEML library provided by the system.
