Form hanging.

[aannn]

Hi..
I have 2 forms. Form1&form2
code in form1

     BackgroundWorker Bw = new BackgroundWorker();
    private void Form1_Load(object sender, EventArgs e)
        {
             serialPort1.Open();
                        
        }
      private void serialPort1_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
        {
            int bytes = serialPort1.BytesToRead;

            serialPort1.Read(byte_buffer, 0, bytes);

            if (byte_buffer[0] == startup)
            {
              
                                
            Bw.DoWork += new DoWorkEventHandler(backgroundWorker1_DoWork);
              Bw.RunWorkerAsync();
            }
        }

        private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
        {
            Form2 f2=new Form2();
           f1.Close();
           f2.Show();
        }

This is my code.mY problem is that form1 is not closing and form2 displays but it hangs 2 or three minutes.And form2 doesnot showing any of controls like textboxes,butto ns etc.I tried so many times..But I didn't get any solution.Please help me.:

Well it looks like you are reading data from a serial port and while you are reading you are creating a new Form2 object...

Have you considered reading all of the data into memory and then passing the information to a Form2 instance (or multiple Form2 instances if necessary)?

I have a feeling that you are running into problems opening multiple Form2 instances as you are reading information in your main Form1 instance and this is causing your problems.
