Getting Data

DarylPope

Application Builder 5.09
PS SDK using C#
I am very new to Robot Application Builder. So I am going through the manual and trying examples that the manual gives and having some problems.
 
I have this at the top just under public partial class Form1.
private Controller controller = null;
private NetworkScanner scan = new NetworkScanner();
private ControllerInfoCollection controllers;
Then in Form1_Load() I have of test for scan object simaler to what your examples show except I just wanted to see if it works and am not displaying the data so I just have.
this.scan.Scan();
controllers = scan.Controllers;
and it works.
Next I wanted to test reading data from the controller so I created an button and placed this code in it.
RapidData rd = controller.Rapid.GetRapidData("T_Rob1", "User", "reg1");
However when I try to run it I get and error telling me
System.NullReferenceException was unhandled
Message="Object reference not set to an instance of an object."
at System.Threading.ThreadHelper.ThreadStart()
and states that I need to create a new instance of the object.
So I added this to the bottom of the Form1_load code.
controller = new Controller(controllers[0]);
now I get and error saying:
System.ComponentModel.LicenseException was unhandled
Message="A valid license cannot be granted for the type ABB.Robotics.Controllers.Licenses.PCSdk. Contact the manufacturer of the component for more information."
Source="ABB.Robotics.Controllers"

I also have the same error when trying to get mastership.
Can you help.

Search the RAB help and this forum under for the word "license" and you should information about the license references you must add to your project.
