I m trying to Dial mobile phone via C# program. Below Show my Program. In this, When i Click my Dial Button it dial the number(Destination number) which i given in my program. But after one or two seconds it is disappeared & its not connect to the that destination number. Below Shows my C# code. Pls help me to solve this problem. Thank you.......
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO.Ports;
namespace WindowsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
SerialPort sp = new SerialPort();
sp.PortName = "COM10";
sp.BaudRate = 9600;
sp.Parity = Parity.None;
sp.DataBits = 8;
sp.StopBits = StopBits.One;
sp.Handshake = Handshake.XOnXOff;
sp.DtrEnable = true;
sp.RtsEnable = true;
sp.Open();
if (!sp.IsOpen)
{
MessageBox.Show("Serial port is not opened");
return;
}
sp.WriteLine("AT" + Environment.NewLine);
sp.WriteLine("ATD=\"" + "Destination Number" + "\"" + Environment.NewLine);
}
}
}
Finally i found the solution. We should add the semi-colon to end of the destination number. then its worked.
sp.WriteLine("ATD=\"" + "Destination Number;" + "\"" + Environment.NewLine);
Increase your BaudRate to max and use this AT Command:
ATD = DestinationNumber;
This will not work with out ; as the system will think you are taking a data call and not a voice call.
Try moving the decleration of the 'sp' outside the method, like so:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO.Ports;
namespace WindowsApplication1
{
public partial class Form1 : Form
{
private SerialPort sp;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
sp = new SerialPort();
}
private void button1_Click(object sender, EventArgs e)
{
if (sp.IsOpen)
{
sp.Close();
}
sp.PortName = "COM10";
sp.BaudRate = 9600;
sp.Parity = Parity.None;
sp.DataBits = 8;
sp.StopBits = StopBits.One;
sp.Handshake = Handshake.XOnXOff;
sp.DtrEnable = true;
sp.RtsEnable = true;
sp.Open();
if (!sp.IsOpen)
{
MessageBox.Show("Serial port is not opened");
return;
}
sp.WriteLine("AT" + Environment.NewLine);
sp.WriteLine("ATD=\"" + "Destination Number" + "\"" + Environment.NewLine);
}
}
}
Here is my working dialing cord it rings the phone
Don't knows that how to get the voice input and out put from port I'm using huwavi E173 dongle.Here is my working cord C#
SerialPort port = new SerialPort();
port.Open();
string t = port.ReadExisting();
Thread.Sleep(100);
string cmd = "ATD";
Thread.Sleep(100);
string phoneNumber = "071********";
Thread.Sleep(100);
port.WriteLine(cmd + phoneNumber + ";\r");
port.Close();

I am testing a real-time port view for serial port.
The Form1 and debug state with always false is shown below.
When Form1 is created, the COM port list is stored in recordedPorts and timer1_Tick event is generated every 100ms, the current COM port list is read and stored in presentPorts and compared with recordedPorts. If you look at the debug state picture, you can see that the result value string[] each of GetPortNames() method is the same.
I want to display COM ports in comboBox1 in real time.
However, it could not be displayed in the comboBox1.
There was a problem in string operation, so timer1_Tick event could not be operated normally.
The first question is to know why string real-time comparison is always false,
and the second is whether there is any other way to display the serial port in real time.

recordedPorts = presentPorts;
return;
}
if (recordedPorts != presentPorts)
{
comboBox1.DataSource = presentPorts;
recordedPorts = presentPorts;
}
}
}
}
The debug state that is always false is as follows.
Thanks to Klaus Gütter.
I resolved this question by comparing the content of the arrays instead of the array references.
Change it to the code below and it works normally.
if (!recordedPorts.SequenceEqual(presentPorts))
//if (recordedPorts != presentPorts)
{
comboBox_port.DataSource = presentPorts;
recordedPorts = presentPorts;
}
I am doing a project in which i have to send the variable data from my console application project to windows form application( i have to write that data into textbox).

This is my trail of console application:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using WindowsFormsApplication2;
using System.Windows.Forms;
namespace ConsoleApplication1
{
class Program1
{
private int val;
public int Val
{
get { return val; }
set { val = value; }
}
static void Main(string[] args)
{
Program1 serial = new Program1();
serial.Val = 1;
System.Windows.Forms.Application.Run(new Serial_comm_1(serial.Val));
//Serial_comm_1 serial_form1 = new Serial_comm_1(serial.Val);
}
}
}
From your app you want to start the other app:
// Create a new Process
System.Diagnostics.Process process = new System.Diagnostics.Process();
process.StartInfo = new System.Diagnostics.ProcessStartInfo();
process.StartInfo.FileName = #"C:\Projects\Temp912\bin\Debug\Temp912.exe";
process.StartInfo.Arguments = "Test Argument";
process.StartInfo.UseShellExecute = false;
process.Start();
Now from your Windows Form App, modify the Main method:
using System;
using System.Windows.Forms;
namespace Temp912
{
static class Program
{
[STAThread]
static void Main(string[] args)
{
string arg1 = "";
if ((args != null) && (args.Length > 0))
{
arg1 = args[0];
MessageBox.Show("Arg1: " + arg1, "Arg App Started With Parameter");
}
else
{
MessageBox.Show("Arg1: N/A", "Arg App Started Without Parameter");
}
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
}
}
If you need to pass the parameter value(s) to your Main Form, expose a property or properties on your form, and set the value(s) before you launch the form.
Edit Per Question:
Form Code
public string MyProperty { get; set; } // change the data type to int or whatever
Than in Program.cs, instead of:
Application.Run(new Form1());
Do this:
// create an instance of your form
Form1 form1 = new Form1();
// set the property or properties
form1.MyProperty = arg1;
Then call:
// this is should work, I didn't test this like the other code
Application.Run(form1);
I'm trying to make GUI for my arduino analogread. The GUI display graph and text line of the value that arduino read. I'm using zedgraph for graphing.
I need to write "on" in the serial monitor window of arduino to start the readings. it runs well. But when I try to control via GUI I made with C# Visual
Studio, the reading won't start. it says "Access to the port 'COM3' is denied".
Here's my arduino code:
void loop() {
while (Serial.available() > 0)
{
input += (char) Serial.read(); // Read in one char at a time
delay(5);
} if (input == "on")
{
myservo.write(0);
---analog reading and Serial.println arduino---
} if (input == "off")
{
myservo.write(115);
}
}
And this is my visual studio code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;

using System.Threading.Tasks;

namespace concentrationMeasurement
{
public partial class Form1 : Form
{
private SerialPort myport;

private string in_data;
public Form1()
{

}
private void btnStart_Click(object sender, EventArgs e)
{
myport = new SerialPort();
myport.BaudRate = 115200;
myport.PortName = port_name.Text;
myport.Parity = Parity.None;
myport.DataBits = 8;
myport.StopBits = StopBits.One;
myport.DataReceived += myport_DataReceived;
try
{
myport.Open();
myport.WriteLine("on");
data_tb.Text = "";
}
catch (Exception ex)
{
MessageBox.Show(ex.Message,"Error");
}
}
private void myport_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
in_data = myport.ReadLine();
this.Invoke(new EventHandler(displaydata_event));
}
private void displaydata_event(object sender, EventArgs e)
{
datetime = DateTime.Now;
string time = datetime.Hour + ":" + datetime.Minute + ":" + datetime.Second;
data_tb.AppendText(time + "\t\t" + in_data + "\n");
}
private void btnStop_Click(object sender, EventArgs e)
{
try
{
myport.Close();
}
catch (Exception ex2)
{

}
}
private void save_btn_Click(object sender, EventArgs e)
{
try{
string pathfile = #"C:\Users\ajis.aprl\Documents\TA bgt\data_GUI\";
string filename = "concentration.txt";
System.IO.File.WriteAllText(pathfile + filename, data_tb.Text);

myPane.Title.Text = "Concentration Growth";
myPane.XAxis.Title.Text = "time";
myPane.YAxis.Title.Text = "concentration";
}
}
}
So I got 2 problem here:
As I said, I can't run my analog reading via GUI, it says "Access to the port 'COM3' is denied".
in myPane.Title.Text, myPane.XAxis.Title.Tex, and myPane.YAxis.Title.Text, there's error in "Text" it says:
"Error 3 'string' does not contain a definition for 'Text' and no extension method 'Text' accepting a first argument of type 'string' could be found (are you missing a using directive or an assembly reference?)"
I googled everywhere but I can't find the answer. Please if anyone know what I'm missing. Can you tell me what's wrong with my code/logic? Thank you.
my eventual aim is to receive data and display it as both a graph and in individual text boxes (or something better!) the data is 2 x temperature readings and a humidity reading, for example the data sent would be "222160" etc.
However before I even tackle that I am having issues simply showing any data in a textbox. This is the code I am using; (Consists of a textbox for the UI)
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;

namespace WFARxSimple
{
public partial class Form1 : Form
{
string rxString;
public Form1()
{
InitializeComponent();
myport = new SerialPort();
myport.PortName = "COM5";
myport.BaudRate = 9600;
myport.Parity = Parity.None;
myport.DataBits = 8;
myport.StopBits = StopBits.One;
myport.Open();
}
private SerialPort myport;
private void DisplayText(object sender, EventArgs e)
{
showRx.AppendText(rxString);
}
private void myPort_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
rxString = myport.ReadExisting();
this.Invoke(new EventHandler(DisplayText));
}
}
}
However I cannot get any data to show in my textbox.
You need, at the very least: myPort.DataReceived += myPort_DataReceived;. Do this in Form1().
I tried to connect the scale and retrieve the weight from visual studio 2013, but it's wire that sometimes I can get the exacted weight and sometimes I couldn't. I was not sure what's wrong with the code. Can someone help? My code is listed below

Often with serial communication, you have to read multiple times, and concatenate each read, until you finally detect you've read the part that shows you've received it all. Detecting the end may be based on a specific count of bytes received, or it might be looking for a particular byte or sequence of bytes. But it's up to you to make that determination, and to continue reading until that condition is fulfilled. When you first read, there may be characters waiting, but the device has not sent them all yet, so you will have to read again almost immediately after your first read. You're dealing with a stream. The handler event fires when the stream starts, but it doesn't know how long the stream will flow.
This blog post discusses this and some other common serial port issues:
