Hello

Necessary to increase the serial number and store the value in the variable to the data card. These actions are necessary to make as conditions change. I read that I can use for this add - in. But I do not understand how to organize the dll file. Can you please tell how to solve this problem.

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?
