Talk.exe Shares Global Memory Between Applications

ID: Q47499

The information in this article applies to:

Microsoft Windows Software Development Kit (SDK) versions 3.0, 3.1

SUMMARY

Talk.exe 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.
