Now not so many developers remember how to write a simple DLL, and what are special features of different system binding. Using several examples, I will try to show the entire process of the simple DLL's creation in 10 minutes, as well as to discuss some technical details of our binding implementation. I will show the step-by-step process of DLL creation in Visual Studio with examples of exchanging different types of variables (numbers, arrays, strings, etc.). Besides I will explain how to protect your client terminal from crashes in custom DLLs.
