Here's another Quickr Tip. Quickr Domino has a very powerful Event model which allows to intercept and modify certain events. You can use either C/C++ or Domino agents to intercept various events. Before writing hook interfaces, you need to decide which method is most appropriate for your environment. You also can combine C/C++ code and Agent code on one server. Using C/C++ for hooking into the events is the fastest method and reduces the impact on the server to a minimum. When writing C/C++ hooks, make sure the C/C++ code is clean and error codes are checked properly, because a crash in your C/C++ hook will crash the Quickr Domino server as well.
The previous example that showed how to use C/C++ hooks was specific for Quickr Domino 8.2. There's now an updated example specific for Quickr Domino 8.5. The example shows how to use Visual Studio and provides sample code that you can download and play with.
