I do not understand how I can use dll runtime libraries. Let dll described two methods. In order to apply the software to one of the methods I have to write something like this: <name of the dll>. <Method name>. If I add this dll in the administration tool, and run it on the transition from one state to another, is what will make this dll. How to apply it to the method that I need?
