Windows C++ Functions Upgrade Requirements

Windows functions (WinC and WinNTC) created with CA Plex releases earlier than r6.0 must be recompiled to be compatible with the CA Plex r7.1 C++ run‑time system.

A single Windows application cannot contain DLLs created with different releases of CA Plex (except in the case of r6.0, r6.1, r7.0, and r7.1). CA Plex includes a run-time version check whenever a generated DLL calls another. A run-time error occurs if you attempt to make a call between DLLs created with incompatible releases. In your development environment, you need to rebuild all of your application DLLs when you move from CA Plex r5.5 or earlier up to CA Plex r7.1.

For more information about run-time applications, see the Running Applications Created with Different Versions of CA Plex in the online help.

For more information about the new features in CA Plex r7.1, see the New Features chapter in this guide.
