Serial port C# wpf received data continuous

Hi,
Sorry still a little new to this forum didn't see your post until now!

If you are using .NET2 Serial Port class you use an event handler delegate (called belive it or not name_of_port.DataReceived += SerialDataEventHandlerNAME have a look on google also www.lvr.com for examples.  My example is pasted below

myComPort.DataReceived += new System.IO.Ports.SerialDataReceivedEventHandler(port_DataReceived_1);

--------





  private void port_DataReceived_1(object sender,SerialDataReceivedEventArgs e) 
  {
  InputData = myComPort.ReadExisting();
  if (InputData != String.Empty)
  {
  this.BeginInvoke(new SetTextCallback(SetText), new object[]{ InputData});
  // label1.Text = label1.Text + "I got some data";
  }
  }
 
  private void SetText(string text)
  {
  this.rtbIncoming.Text += text;
  }


There is a way to poll the read function with a timer, though this can get a bit erratic in large programs 
 
private void tmrPollForRecievedData_Tick(object sender, EventArgs e)
{

string charToRead;
while (myComPort.BytesToRead > 0)
{
charToRead = (myComPort.ReadExisting());

rtbIncoming.Text = rtbIncoming.Text + (charToRead);//+ System.Convert.ToString(charToRead);
}

tmrPollForRecievedData.Enabled = false;
}

The down side with this is the timer component is maskable by the processor so this simple method can lead to some data going missing using DataRecieved Event gets around this. 

Also to avoid locking the form  use the non blocking method ReadExisting() which will return data that has been read.
