I am currently trying to figure out how to take the pre-existing camera items in my RDK workstation and activate them instead of doing a Cam2dAdd and making new cameras.
Is there a way to do this in the C# API?
I found it odd that there is a Cam2dClose function, but no Cam2dOpen.

Hello,

This is possible using the setParam method in Python, which I think is SetParameter in C#.

Code:

camera = RDK.Item('Camera 1')
camera.setParam("Close") #"Open to start the camera

Hello,

Code:

camera = RDK.Item('Camera 1')
camera.setParam("Close") #"Open to start the camera

I tried the following in C#

camera.setParam("Open")

and I get the following error despite the camera activating in the RDK window.

"A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond"

Note: I am using the RoboDK.cs from the SampleProject for this, if that matters.

Hello,

Here is the code I tried and it works fine. Can you try this?

Code:

using System;

namespace SimpleNetcoreApplication
{
    public class Program
    {
        static void Main(string[] args)
        {
            var rdk = new RoboDK();

            // Connect to existing RoboDK or start a new one if RoboDK is not running
            var status = rdk.Connect();
            Console.WriteLine($"Connect status: {status}");

            //RoboDK _RDK = new RoboDK();
            RoboDK.Item camera = rdk.getItem("Camera 1");
            camera.setParam("Open");

            // close RoboDK
            //rdk.CloseRoboDK();

        }
    }
}

Hope this helps you.

            camera.setParam("Open");

            // close RoboDK
            //rdk.CloseRoboDK();

        }
    }
}

Hope this helps you.

I inserted the code into the function and executed it.
"Connect status: True" is printed to the Console, and then the program crashes.

/// <summary>
        /// Send a specific parameter to RoboDK. This is reserved for internal purposes.
        /// </summary>
        /// <param name="param">Item parameter</param>
        /// <param name="value">value</param>
        /// <returns></returns>
        public string setParam(string param, string value = "")
        {
            link._require_build(7129);
            link._check_connection();
            link._send_Line("ICMD");
            link._send_Item(this);
            link._send_Line(param);
            link._send_Line(value);
            string response = link._recv_Line(); <<< Crash Happens Here
            link._check_status();
            return response;
        }

It appears to crash while waiting for a response from the RDK window.
I'm curious if I am using an old version of the API code.
