I got a question for the community. I followed some somewhat recent tutorial on a speech-to-text kinda deal. It worked for him and not for me, so do you have any suggestions?

GrammarBuilder gBuilder = new GrammarBuilder();
gBuilder.Append(commands);
Grammar grammar = new Grammar(gBuilder);
recEngine.LoadGrammarAsync(grammar);
recEngine.SetInputToDefaultAudioDevice();
recEngine.SpeechRecognized += RecEngine_SpeechRecognized;

break;

On visual studio code; I'm trying to get a text box to be used as a speech to text. However, when I enable it no error get thrown, nor does any speech appear. So, not entirely sure were I went wrong here. Very new to C# and visual studio. Any help is appreciated!! :) My mic is set to the default device and is able to detect me speaking. Other function such as copy to clipboard and clear work.

I am developing a graphical interface that reads variables from different sensors that arrive through the serial port, so far I have managed to read all the variables with a single form but now I want to have two forms.
The first form asks the user to choose the COM and confirms whether the connection was successful or not. Once the connection is successful, the second form is opened where the variables from the sensors will be shown in "labels", the readings sent from Arduino are read by the serial port and stored in an array:
data[0], data[1], data[2] etc...
This is the first form where Serialport1 is found and the data arrives through the serialPort1_DataReceived event:

I hope someone can help me overcome this problem.
The code is as follows:
The ServerForm Code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

public partial class ServerForm : Form
{

{

}

private void Form1_Load(object sender, EventArgs e)
{
server = new SimpleTcpServer();
server.Delimiter = 0x13; //enter
server.StringEncoder = Encoding.UTF8;
server.DataReceived += Server_DataReceived;
}
private void Server_DataReceived(object sender, SimpleTCP.Message e)
{
StatusText.Invoke((MethodInvoker)delegate ()
{
StatusText.Text = e.MessageString;
e.ReplyLine(string.Format("You said: {0}",e.MessageString));
});
// throw new NotImplementedException();
}
private void label1_Click(object sender, EventArgs e)
{
}
private void StartButton_Click(object sender, EventArgs e)
{
StatusText.Text += "Server Starting !";
System.Net.IPAddress ip = new System.Net.IPAddress(long.Parse(HostText.Text)); //error here
server.Start(ip,Convert.ToInt32(PortText.Text));
}
private void StopButton_Click(object sender, EventArgs e)
{
if(server.IsStarted)
{
server.Stop();
}
}
}
}
The Code of the ClientForm is as follows:
using SimpleTCP;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace Client
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
SimpleTcpClient client;
private void ConnectButton_Click(object sender, EventArgs e)
{
ConnectButton.Enabled = false;
}
private void Form1_Load(object sender, EventArgs e)
{
client = new SimpleTcpClient();
client.StringEncoder = Encoding.UTF8;
client.DataReceived += Client_DataReceived;
}
private void Client_DataReceived(object sender, SimpleTCP.Message e)
{
StatusText.Invoke((MethodInvoker)delegate ()
{
StatusText.Text = e.MessageString;
//...
});
//throw new NotImplementedException();
}
private void SendButton_Click(object sender, EventArgs e)
{
client.WriteLineAndGetReply(TextMessage.Text, TimeSpan.FromSeconds(4));
}
}
}
The issue in the above code is that it is 'build'ing correctly and even when I am debug it with the new instance, the code is running fine, but will I debug, as soon as I press the "start" button in the Server form it shows the error in line :
System.Net.IPAddress ip = new System.Net.IPAddress(long.Parse(HostText.Text));
The error is: System.FormatException: 'Input string was not in a correct format.'
Please refer the Screenshot for details and suggest a potential fix to the issue.Image of Screenshot of Error inLine
Clearly HostText.Text is returning a value that can't be parsed into a long.
This exception is coming from long.Parse, which is really a language shortcut for Int64.Parse, whose documentation states that it will throw this exception if the input string is not formatted correctly.
I have three commands to execute waiting for each command to finish before starting the next one.
Based on my implementation after completing the first one the second one will start but backgroundWorker1_RunWorkerCompleted won't raise at all.

}

{

}
}
}
BackgroundWorker is one time usage only i.e once the state is Completed it wont restart, u need to re-instantiate it.
private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
command++;
if (command < commands.Length)
{
backgroundWorker1 = new BackgroundWorker();
backgroundWorker1.DoWork += this.backgroundWorker1_DoWork;
backgroundWorker1.ProgressChanged += this.backgroundWorker1_ProgressChanged;
backgroundWorker1.RunWorkerCompleted += this.backgroundWorker1_RunWorkerCompleted;
backgroundWorker1.RunWorkerAsync();
}
