I have code that takes data from serial com port from a weighing machine. It works okay, but receives data in several lines. I'm trying to make it receive data in one line.
In the code below I need to take weight from weigh bridge machine automatically by timer using Visual Studio 2005. It works, but I receive weight values on several lines.
I need to receive weight in one line and automatically update and convert it to an integer.

I am a newbie in C# and I have questions as below:
I have a Form1 name is setting Port Name, Baud Rate, Parity... of modbus protocol and I can open serial Port.
Also, I have another Form is called Form2, When Port is opened i want to close Form1 and Port alway Open => I can do it. But this problem that was I want to get data such as FC03 HolodingRegister, FC01 WriteSingleCoil... for Form2 but didnot.
I used delegate to transfer data from Form 1 to Form 2 but I could not use button Form2 to send FC01 signal.
How to use FC01, FC03,04... for Form2 when Form 1 connected.

When I understand you right, you will in Form1 open a connection, close the Form, open a new Form2 and use this connection there?
Well, when that's the case, you could make an special Connection Singleton to hold this connection then you can use it in your Form2
using System;
namespace Sandbox
{
public sealed class Connection
{
private static readonly Lazy<Connection> _instance = new Lazy<Connection>(() => new Connection());
public static Connection Instance => _instance.Value;
private Connection()
{ }
// Implement your Connection Code here.
}
}

You are instantiating a local variable, not the field.
Instead of

Try
aSerialPort = new SerialPort(cbbx_comport.Text);
I've been trying to use a proxy on my webBrowser1.Navigate request using the following stackoverflow answer: https://stackoverflow.com/a/9036593/7443548
But this code would crash my for loop which I'm running in my own code.
How could I use a proxy for each request inside my code function?
Function which needs to use a proxy:
private void backgroundWorker_DoWork(object sender, DoWorkEventArgs e)
{
Uri currentUri = new Uri(bunifuMaterialTextbox1.Text);
int views = bunifuSlider1.Value;
for (int i = 0; i < views; i++)

{
bunifuCustomLabel9.Text = "Finished";
MessageBox.Show("Finished", "YoutubeViewBot response");
}
private void bunifuFlatButton1_Click(object sender, EventArgs e)
{
}
}
}
Steps it should do:
On click on the button: bunifuFlatButton2_Click it should start the backgroundWorker_DoWork functon
backgroundWorker_DoWork should run the loop x times and for each run it should attach a new proxy to the request
I would appreciate any kind of help.
Edit 1:
While debugging step by step, I realized the for loop crashes after running the second time on the following line:
HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();
Video can be seen here:
https://www.youtube.com/watch?v=H3y2jFvuK3M
It finished after running the for loop twice instead of 454 times.
Trying to develop small application using GsmComm Library.
At the moment a have some problems with detecting if phone is connected or no.
it's detects when phone is disconnected, but doesn't want to detect phone when is connected back again ...
Any idea why ?
my code:
GsmCommMain gsm = new GsmCommMain(4, 115200, 200);
private void Form1_Load(object sender, EventArgs e)
{
gsm.PhoneConnected += new EventHandler(gsmPhoneConnected);
gsm.PhoneDisconnected += new EventHandler(gsmPhoneDisconnected);
gsm.Open();
}
private delegate void ConnctedHandler(bool connected);
private void onPhoneConnectedChange(bool connected)
{
try
{
if (connected)
{
phoneStatus.Text = "OK";
}
else
{
phoneStatus.Text = "NG";
}
}
catch (Exception exce)
{
logBox.Text += "\n\r" + exce.ToString();
}
}
public void gsmPhoneConnected(object sender, EventArgs e)
{
this.Invoke(new ConnctedHandler(onPhoneConnectedChange), new object[] { true });
}
private void gsmPhoneDisconnected(object sender, EventArgs e)
{
this.Invoke(new ConnctedHandler(onPhoneConnectedChange), new object[] { false });
}
Sorry for late answer. Just noticed your question.
There is no need to use EventHandler for connection. If you want to call some functions after phone/gsm modem is connected you should call them after you opened port and (!) checked whether connection is established using IsConnected() member function in GsmCommMain class.
var gsm = new GsmCommMain(4, 115200, 200);
