Hi guys i have problem i make code that take data from serial com port for weighting machine
it is ok working but it recieve data in more lines.I try to make it receive data in one line
In code below i need to take weight fro weight bridge machine automatically by timer in visual studio 2005.it works but receive weight values in more lines.
I need to receive weight in one line and automatically updated then convert t to integer

void Application_Idle(object sender, EventArgs e)
{
label3.Text = serialPort1.IsOpen ? "[Open]" : "[Closed]";
}
private void button1_Click(object sender, EventArgs e)
{
if (pollingCheckbox.Checked)
{
timer1.Enabled = true;
}
else
{
timer1.Enabled = false;
TransmitCommand();
}
}
private void TransmitCommand()
{
if (textBox1.Text.Length > 0)
{
if (serialPort1.IsOpen)
{
serialPort1.Write(textBox1.Text + "\r");

}
}
}
private void ClosePort()
{
if (serialPort1.IsOpen)
{
serialPort1.DataReceived -= new SerialDataReceivedEventHandler(serialPort1_DataReceived);
serialPort1.Close();
}
}
private void closePortToolStripMenuItem_Click(object sender, EventArgs e)
{
ClosePort();
}
private void exitToolStripMenuItem_Click(object sender, EventArgs e)
{
Close();
}
private void Form1_Load(object sender, EventArgs e)
{
serialPort1.PortName = Properties.Settings.Default.Port;
serialPort1.BaudRate = Properties.Settings.Default.Baud;
serialPort1.DataBits = Properties.Settings.Default.DataBits;
serialPort1.Parity = (Parity)Enum.Parse(typeof(Parity), Properties.Settings.Default.Parity);
serialPort1.StopBits = (StopBits)Enum.Parse(typeof(StopBits), Properties.Settings.Default.StopBits);

Application.Idle += new EventHandler(Application_Idle);
}
private void OpenPort()
{
serialPort1.Open();
serialPort1.DataReceived += new SerialDataReceivedEventHandler(serialPort1_DataReceived);
}
private void openPortToolStripMenuItem_Click(object sender, EventArgs e)
{
OpenPort();
}
private void optionsToolStripMenuItem_Click(object sender, EventArgs e)
{
ClosePort();

using (Form2 form = new Form2())
{
if (form.ShowDialog(this) == DialogResult.OK)
{
serialPort1.PortName = Properties.Settings.Default.Port;
serialPort1.BaudRate = Properties.Settings.Default.Baud;
serialPort1.DataBits = Properties.Settings.Default.DataBits;
serialPort1.Parity = (Parity)Enum.Parse(typeof(Parity), Properties.Settings.Default.Parity);
serialPort1.StopBits = (StopBits)Enum.Parse(typeof(StopBits), Properties.Settings.Default.StopBits);
}
}
}
void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
if (!InvokeRequired)
{
if (e.EventType == SerialData.Chars)
{
string portData = serialPort1.ReadExisting();
textBox2.AppendText(portData);
}
}
else
{
SerialDataReceivedEventHandler invoker = new SerialDataReceivedEventHandler(serialPort1_DataReceived);
BeginInvoke(invoker, new object[] { sender, e });
}
}
private void pollingCheckbox_CheckedChanged(object sender, EventArgs e)
{
if (timer1.Enabled && !pollingCheckbox.Checked)
{
timer1.Enabled = false;
}
}
private void timer1_Tick(object sender, EventArgs e)
{
if (pollingCheckbox.Checked)
{
TransmitCommand();
}
}

}
