Not getting response from Lane Control Board

Not getting response from Lane Control Board - c#

I'm trying to get inputs/outputs from a LCB(lane control board),which in serial. I'm using prolific usb-serial as the interface . I'm new to programming,but i've managed to get send/receive inputs when i shorted pin 2 and 3 of DB9 together . But when i plugged the db9 connector to the LCB , it can send , but not receiving any .
I'm using VS2010 in Windows 10.
Below are my snippets ;

C# InvaildOperationException Collection was modified

I am having an issue with my C# application, it runs fine or x amount of minutes but hits an error at some point which complains about 'InvaildOperationException Collection was modified'. I am quite new to C# and i am unable to find the solution even after reading other posts.
From what i can tell after reading the posts it is something to do with my for loop, could anyone be so kind as to tell me what i have done wrong.
The error i think is caused by the UpdateGraph function.
The code is designed to connect to a Cisco router and get the cellular data via Serial and show it in a graph and richTextBox which is all working minus the error i get at some point :(

Serial Port Unauthorized Exception

I am trying to access RFID Reader through Arduino application which gives me the right output on control monitor.
But when I tried to access it through visual studio C#, it works only once and then gives me access is denied! And also stopped working on Arduino IDE.
//Function to initialize serial port

}
catch (UnauthorizedAccessException ex) {MessageBox.Show( ex.Message); }

I put the function here:

Real Time Chart with Serial port Data in C#

I want to drawing real time chart in c# with my data that read from serial port Arduino device i didn't know how can i do this with c#.
i want 2d and 3d chart in my program anyone can help me ?
in my program i read data from serial port and time of data has been arrived so my chart be have 2 data one of them is info and another is time.

The problem is that in line
series.Points.AddXY(System.DateTime.Now, Values[i]);
you are adding points with the same X value set to System.DateTime.Now. In result you have only one point on axis X.

c# Serial DataReceived very slow

I've trying to communicate with an Arduino Due in C#. The communikation works quite well, but my DataReceived handler needs about 1 second to react. This is my problem because I have to send up to 1 billion (1*10E9) commands.
If I activate a DEBUG Setting in the Arduino, it tells me that it's need 64 Milliseconds for a command. I think the C# the App should get it no later than 80 Milliseconds after sending it.
Here is a Part of the Code:
StopWatch s1 = new StopWatch();
private void Open_Port()
{
string port = null;
int baud = 0;
bool ERR = false;
if ((COM_cb.SelectedItem != null) | (BAUD_cb.SelectedItem != null))

port = this.COM_cb.GetItemText(this.COM_cb.SelectedItem);
baud = Convert.ToInt32(this.BAUD_cb.GetItemText(this.BAUD_cb.SelectedItem));
ERR = false;
}
else
{
ERR = true;
System.Windows.Forms.MessageBox.Show("Error Msg");
}

Does anyone an Idea why c# needs so long to call the datahandler?
Sincere regards,
Fabian Harmsen
UPDATE
- Added comment to DataHandler (24.02.2016 16:30 Europa/Berlin)

The problem lies in the serialPort1_DataReceived received data handler.
I ran a separate thread with a while(true) loop and serial.ReadLine(), all works perfectly.
Hope someone else doesn't need to spend 3 hours fixing this.
using System.Threading;
public void main()
{
setup();
Thread readThread = new Thread(Read);
readThread.Start();
}
public void Read()
{
while(true)
{
try
{
string message = serialPort1.ReadLine();
}
catch (Exception)
{ }
}

How to add realtime data from OPC client to user control using c#

I created an OPC client to connect to KepServerEX, I got realtime data from KepServerEX and now I want to add realtime data to user control that contains a textbox.
Realtime data will be updated via value_changed event.
I created Windows Form Application and added textbox to Form to display realtime value, I can not post images here.
This is my code:
namespace OPC_Client
{
public partial class Form1 : Form
{

OPCGroup KepGroup;

Now I want to create some User Controls to display some tag values.What should I do?

This is a pretty big topic in itself, but I have implemented such a beast a few years back in C#, also using KepServerEx.
Without seeing your code it's a bit difficult for me to understand what you have done so far, but the general idea is that you want to handle the OPCGroup.DataChange event. From there you have to "dispatch" the changed value to the proper TextBox.
Of course, you have to setup your OPCServer, your OPCGroup(s) and so on.
I created a library for this, and it was some extensive work required, so I'm afraid it can't really be answered in one Q&A like here.
If you have a very specific question, please open another one and I'll try to answer more specifically.
Cheers
