Problem is I couldn't understand how to do Threading. I have tried but faced with the same problem.

Problem causes when I add this lines

 
chartResult.Series[0].Points.AddXY(i, realDatas[i]);          chartResult.Series["onLineAvg"].Points.AddXY(i, onLineAvg[i]);chartResult.Series["multOnLineAvg"].Points.AddXY(i, multOnLineAvg[i]);

Thank you very much. I have added

private void backgroundWorkerGetAndProcessData_DoWork(object sender, DoWorkEventArgs e)        {            communicateNow();        }

and called with

backgroundWorkerGetAndProcessData.RunWorkerAsync();

when RunWorkerCompleted recalled it with

private void backgroundWorkerGetAndProcessData_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)        {            backgroundWorkerGetAndProcessData.RunWorkerAsync();        }

now get System.InvalidOperationException: 'Collection was modified; enumeration operation may not execute.' error

Thank you for your response. Yes device waits command to response so I have to send some data with write command and wait for response from device with read method. I will try BackgroundWorker class which I have never try. Also if I comment communicateNow() Program is not going to stuck but every time that I want to get data from device must click on receive button.

When I add port.Write my problem solved. This is about modbus protocol I think device was waiting to get response

I have set lots of break point and I've seen that ListLines[i] is null everytime. But the counter is true I have seen it as 5 and productcodefilecounter is 5 also.

alidayan 25-Jul-14 6:29am View

Thank you for your attention. now I have another problem.

for (i = 0; i < counter; i++)
{
if (comboBox1.Text == ListLines[i])
{
urunkodu = Convert.ToUInt32(ListProductCodeFileLines[i]);
}
}

is not working but there is no ex.Message it could not find the product code from productcode.txt
