Error initializing handshake with http://127.0.0.1 - c#

Okay so I have been using SocketIO4Net.Client recently and I have ran into a problem. I call the Go function in the Hello class on startup, and as soon at it is called I get an error 'Error initializing handshake with http://127.0.0.1'
Here is my test.php file that I connect to using SocketIO package
<script src="https://api.icbit.se/socket.io/socket.io.js"></script>
<script src='https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js'></script>
<script>
$(document).ready(function () {
var conn = io.connect('http://api-url');
conn.on('connect', function () {
alert('Connected');
conn.emit('message', { op: 'subscribe', channel: 'orderbook_BUM3' });
});
conn.on('message', function (data) {
console.log('Incoming message: ' + data.private);
});
});
</script>
Here is also my csharp code that I use
using SocketIOClient;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Fag_Ville
{
class Hello
{
public static Client broadcastSocketClient;

broadcastSocketClient.Error += SocketError;
while (!broadcastSocketClient.IsConnected)
{
broadcastSocketClient.Connect();
}
// register for 'connect' event with io server
broadcastSocketClient.On("connect", (cn) =>
{
var namespaceConnect = broadcastSocketClient.Connect("/namespacename");
// register for 'connect' event with io server
namespaceConnect.On("connect", (data) =>
{
namespaceConnect.Emit("test", "CONNECTED");
namespaceConnect.On("first", (message) =>
{
Console.WriteLine(message);
});
});
});
}
public static void SocketOpened(object sender, EventArgs e)
{
Console.WriteLine("SocketOpened\r\n");
Console.WriteLine("Connected to ICBIT API server!\r\n");
}
public static void SocketError(object sender, ErrorEventArgs e)
{
Console.WriteLine("socket client error:");
Console.WriteLine(e.Message);
}
public static void SocketConnectionClosed(object sender, EventArgs e)
{
Console.WriteLine("WebSocketConnection was terminated!");
}
public static void SocketMessage(object sender, MessageEventArgs e)
{
if (string.IsNullOrEmpty(e.Message.Event))
Console.WriteLine("Generic SocketMessage: {0}", e.Message.MessageText);
else
Console.WriteLine("Generic SocketMessage: {0} : {1}", e.Message.Event, e.Message.Json.ToJsonString());
}
public void Close()
{
if (broadcastSocketClient != null)
{
broadcastSocketClient.Opened -= SocketOpened;
broadcastSocketClient.Message -= SocketMessage;
broadcastSocketClient.SocketConnectionClosed -= SocketConnectionClosed;
broadcastSocketClient.Error -= SocketError;
broadcastSocketClient.Dispose(); // close & dispose of socket client
}
}
}

How can I connect to Laravel broadcasting from c# desktop app?

I have laravel chat application working through laravel broadcasting on laravel-echo-server. On front end I subscribe to channels and listen events using laravel-echo npm package, but how can I subscribe to channels in desktop app written on c# ?
I expect to have something like this written on c#:
Echo.private('SomeChannel')
.listen('SomeEvent', (response) => {});

C# WPF - Modify a ComboBox from a different class

I'm writing a small WPF application in C# using Kinect and COMs to communicate to an arduino.
I have a combobox where the user can choose the port that he wants to use, I have a watcher on my COMs and everytime a device is Plugged/Unplugged I want to refresh my combobox.
My problem is that the calling to the function is in another class so I have a thread error
Here is the portion of code that doesn't work :
namespace Microsoft.Samples.Kinect.SkeletonBasics

I'm a little new to C#, I've searched on the web but I can't find an easy solution for doing that, can somebody help me please ?
Add SynchronizationContext to Your WMIReceiveEvent class, like:
public class WMIReceiveEvent : IDisposable
{
private readonly SynchronizationContext _syncContext;
public WMIReceiveEvent(SynchronizationContext syncContext)
{
_cyncContext = syncContext;
}
}
and wrap of calling MainWindow.Refresh_Coms(); with Send method of SynchronizationContext:
_syncContext.Send(o => MainWindow.Refresh_Coms(), null);
And last thing is creating Your WMIReceiveEvent class:
private WMIReceiveEvent receiveEvent = new WMIReceiveEvent(SynchronizationContext.Current);

SerialPort C# custom delegate from DataReceived

I'm doing a class for working with the serial port.
It's all going quiet until the item to receive a data through the serial port, the class raise an event in the main application.
My question is: how to pass parameters to a delegate and use it in my class because my class is so independent.
Below the sources and where I like to spend delegates.
Class control serial port:
using System;

}
public void Abrir(string porta, int velocidade)
{
serialPort.PortName = porta;
serialPort.BaudRate = velocidade;
serialPort.Open();

You seem to be trying to update the text from a non UI thread (if you follow the calls stack you see that the method is triggered from a dedicated thread you spawn):
private void UpdateTextbox(string text)
{
text1.Text += "\r\n";
text1.Text += text;
}
Instead use RunOnUiThread() to schedule the text change to run on the UI thread:
private void UpdateTextbox(string text)
{
RunOnUiThread(() =>
{
text1.Text += "\r\n";
text1.Text += text;
});
}
Also you should get rid of the empty exception catching you do along the way - this most likely masked the problem.
Also always check the catlog for exceptions they usually are a good indicator.
