I am trying to establish a connection between an interface that I made in Visual Studio, Windows Forms, in C# and my controller, I cannot solve this trouble, I have tried 2 differents ways of doing it:

First with tutorials of PC SDK and still does not work, I cannot get the network scanner to scan my controller´s IP addres.

On the other hand I have found on the internet a C# library developed by a person, the library is called Machina, and it also has many examples, but when I introduce the code in my program, it turns out an exception, and I dont know how to manage it.

If anyone knows how to solve this exception please tell me, because I am going bananas.  
Thanks

Hello there,

Have you looked at this post: [ABB Robotics Community - Maintenance](https://forums.robotstudio.com/discussion/12056/pc-sdk-examples)

If yes, can you please be more specific regarding any issues you encounter when trying to get NetScanner to find your controller.

Thanks.

Hi have checked your post, and downloading your source code, I am going to transform it into mine, soi it will work, but I have a question, will it work the same in a different project, because your project is not with windows forms.

Hello Victor,

The code for creating the controller object should be the same regardless if you’re using WPF or WinForms project.
