Logic issue on reading ALL data from the from the listbox that is coming from thread in c#

I am modifying to first question attempt.
I need help passing the data from a listbox and pass it to another method so every time the listbox gets data add it from the tread, it should also send that data to my new method and it to the my list because in that method I will be doing some parsing because the data from the listbox is a long string barcode but I don't need help on parsing the data because I can do that, the part I need help only is to pass the data from thread that is passing it to the listbox it should also be send to my method ReadAllData() so in that method I will received the data and then I will do the parsing the make a return.
Here is the method where the listbox is stored and receives the data from a thread from telnet port 23
Here is the code I need to send the data from the lst_BarcodeScan to the method ReadAllData method and store to my list.

var received = "";
var size = _networkStream.Read(data, 0, data.Length);
if (size == 0)
return null;
received = Encoding.ASCII.GetString(data, 0, size);
return received;
}
public void CloseConnection()
{

Main class that will call the methods from the telnetconnection class or any other classes I will add.

}
private void btn_StopConnection_Click(object sender, EventArgs e)
{
//_connection = new TelnetConnection(Hostname, Port);

_connection.Exit();
}
private void btn_RemoveItemFromListAt_Click(object sender, EventArgs e)
{
for (var i = lst_BarcodeScan.SelectedIndices.Count - 1; i >= 0; i--)
{
lst_BarcodeScan.Items.RemoveAt(lst_BarcodeScan.SelectedIndices[i]);
}
}
private void BarcodeReceivingForm_Load(object sender, EventArgs e)
{
lst_BarcodeScan.SelectionMode = SelectionMode.MultiSimple;
}
private void btn_ApplicationSettings_Click(object sender, EventArgs e)
{
var bcSettingsForm = new BarcodeReceivingSettingsForm();
bcSettingsForm.Show();
}
private void btn_ClearBarcodeList_Click(object sender, EventArgs e)
{
lst_BarcodeScan.Items.Clear();
}
}
}

The easiest way to implement without adding more complexity to the thread is to simply raise an event on the listbox when and item is added to it. The problem is that the listbox do no have any events that allow to do that but you can create your own version with a dozen lines of code.
The goal is to create a derived control of the listbox then you add to it a method to trigger a custom event when an item is added and bingo.
Here's the custom listbox class with the custom EventArgs.
// custom override class over the list box so we can create an event when items are added
public class ListBoxWithEvents : ListBox
{
// the event you need to bind to know when items are added
public event EventHandler<ListBoxItemEventArgs> ItemAdded;
// method to call to add items instead of lst.Items.Add(x);
public void AddItem(object data)
{
// add the item normally to the internal list
var index = Items.Add(data);
// invoke the event to notify the binded handlers
InvokeItemAdded(index);
}
public void InvokeItemAdded(int index)
{
// invoke the event if binded anywhere
ItemAdded?.Invoke(this, new ListBoxItemEventArgs(index));
}
}
// basic event handler that will hold the index of the item added
public class ListBoxItemEventArgs : EventArgs
{
public int Index { get; set; } = -1;
public ListBoxItemEventArgs(int index)
{
Index = index;
}
}
Now you need to change your listbox on your form with the ListBoxWithEvents instead. You have 2 ways to do this but i'll give you the easiest. Compile your code and go in the design window for the form. In your toolbox you should have the ListBoxWithEvents control now and you can simply drag and drop in your form and replace the one you have. Since it derive from the listbox all it has is extra features. It didn't lose anything it had before.
Now you need to change 2 things. In your form select the new ListBoxWithEvents control and go in the properties events and you will find the new event called ItemAdded you can double click that and it should create an event like the following. I have also thrown in a sample MessageBox that display all you will need.
private void ListBox1_ItemAdded(object sender, ListBoxItemEventArgs e)
{
MessageBox.Show("Item was added at index " + e.Index + " and the value is " + listBox1.Items[e.Index].ToString());
}
Finally in order to trigger that event you need to use the new method lst.AddItem(object); instead of lst.Items.Add(object); so according to your sample code you need to change this :
_form.lst_BarcodeScan.Invoke(new MethodInvoker(delegate
{
_form.lst_BarcodeScan.Items.Add(received + Environment.NewLine);
}));
to this :
_form.lst_BarcodeScan.Invoke(new MethodInvoker(delegate
{
_form.lst_BarcodeScan.AddItem(received + Environment.NewLine);
}));
Try it and now you should have that event fire every time something is added to the list.
Since you are pretty new to programming i find it important to mention that this event will trigger on the UI thread and not the thread you created. This mean it behave normally like clicking on a button triggers a button_click(object sender, EventArgs e) event. No special thread involved whatsoever.

UWP Bluetooth Low Energy Application Disconnects Early

So I am designing an application for windows laptops to connect to a custom designed pressure sensor. The application pairs to the device and then receives notifications from the device every 10 ms. Then for some reason the communication stops. I know it is a problem with my application and not with the device, because when I connect to my phone, I do not have this problem.
Here is the main page where I create the devicewatcher and discover the device:

I have researched this extensively, and all I could find was help on how to initiate a disconnection. I have the opposite problem. One page I found stated that the problem might be caused by the device not properly storing the bonding state, but I have checked that and I did initialize the device to save the bonding state.
Interestingly if I do not pair the device to the computer before trying to read information from it then I do not have the problem. The connection never randomly stops. But when I do this, the computer does not receive every packet of data sent from the sensor device. It will receive one or two packets and then skip five or six packets. If I pair the device then I will receive every packet but the connection will randomly cut off.
So my question is two fold, I guess. How do I stop the connection from cutting off when the device is paired? Or alternatively, is there a way to allow the application to receive every packet of data when it is not paired?
UPDATE
I realized I should include more information on my sensor peripheral in case the error is in that code. I am currently designing a rapid prototyping of this sensor before I move on to designing the embedded version. To do this, I am using the BLE Nano 1 from RedBearLabs as a user friendly prototype. I am programing this device with the online MBED compiler. I have included the nRF51822 and BLE_API libraries to handle the bluetooth low energy communication.
UPDATE 2
So after more research into what is causing the problem, I have found that the disconnection occurs when a connection interval and a generation 2 garbage collection occur at the same time. In UWP the garbage collector can pause the UI Thread for generation 2 collections. (see here)
My thought is that if the thread is paused at the beginning of a connection interval, then the central is not able to initiate the connection with the peripheral and the peripheral therefore thinks the client is no longer listening (see more about how BLE connections work).
I discovered this by finding out exactly what is necessary to get the connection back once it has randomly stopped. I started with the entire connection process and reduced it down to this:
public async Task ReconnectDevice()
{
GattCommunicationStatus status = await dataCharacteristic.WriteClientCharacteristicConfigurationDescriptorAsync(
GattClientCharacteristicConfigurationDescriptorValue.Notify);
await WriteByteArray(SensorUUIDs.SensorStateUuid, new byte[] { 0x01 });
}
Because my BluetoothLEDevice, GattService, and GattCharacteristic objects are not disposed, all I need to do is resubscribe to notifications and write a 1 to the device so that it begins collecting data again.
I have reduced my memory allocations in my application significantly since discovering this, and the time for a gen2 collection has decreased to an average of 5 ms. Also, the amount of time before the connection disconnects has increased to around 4-5 sec.
UWP has a GattCharacteristicNotificationTrigger for receiving notifications in a BackgroundTask, but I have never had much success at incorporating background tasks in UWP.
I think I will try next to incorporate the windows.devices into a WPF application where I think I will have a better chance at getting it working.

So, after a while of trying different ideas I have finally stumbled across a solution to my problem. I had to make 2 changes:
Used the unpaired connection instead of the paired connection. This solved the problem of the connection dropping suddenly.
Increased the connection interval to 40 ms. For some reason when I did this, I received all of the data and no longer had any problems. Anything below 40 ms causes information to be lost when communicating to a Windows device (I had to make this change on the C code running on my sensors.)
I have used the devices for about 2 months now after making this change and have had no problems at all.

I seems to me that these problems are related to the BluetoothCacheMode Enum.
This indicates whether certain Bluetooth API methods should operate on values cached in the system or
retrieve those values from the Bluetooth device.
Using BluetoothCacheMode.Uncached attribute allows the service to update the attributes when needed.
If the device is paired then the BluetoothCacheMode is not needed(I think BluetoothCacheMode.Cached is default).
In your code the line:
var services = await leDevice.GetGattServicesAsync(BluetoothCacheMode.Uncached);
Can be the cause of the connection lost if paired.
GetGattServicesAsync(), GetCharacteristicsAsync() and ReadValueAsync()
must have the attribute BluetoothCacheMode.Uncached when not paired, when paired default or BluetoothCacheMode.Cached.

C# WPF - Modify a ComboBox from a different class

I'm writing a small WPF application in C# using Kinect and COMs to communicate to an arduino.
I have a combobox where the user can choose the port that he wants to use, I have a watcher on my COMs and everytime a device is Plugged/Unplugged I want to refresh my combobox.

I'm a little new to C#, I've searched on the web but I can't find an easy solution for doing that, can somebody help me please ?

Add SynchronizationContext to Your WMIReceiveEvent class, like:
public class WMIReceiveEvent : IDisposable
{
private readonly SynchronizationContext _syncContext;
public WMIReceiveEvent(SynchronizationContext syncContext)
{
_cyncContext = syncContext;
}
}
and wrap of calling MainWindow.Refresh_Coms(); with Send method of SynchronizationContext:
_syncContext.Send(o => MainWindow.Refresh_Coms(), null);
And last thing is creating Your WMIReceiveEvent class:
private WMIReceiveEvent receiveEvent = new WMIReceiveEvent(SynchronizationContext.Current);

SerialPort C# custom delegate from DataReceived

I'm doing a class for working with the serial port.
It's all going quiet until the item to receive a data through the serial port, the class raise an event in the main application.
My question is: how to pass parameters to a delegate and use it in my class because my class is so independent.
Below the sources and where I like to spend delegates.
Class control serial port:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO.Ports;
namespace TCCExterna.Lib
{
public class PortaSerial //: IDisposable
{
private SerialPort serialPort;
private Queue<byte> recievedData = new Queue<byte>();
public PortaSerial()
{
serialPort = new SerialPort();
serialPort.DataReceived += serialPort_DataReceived;
}
public void Abrir(string porta, int velocidade)
{
serialPort.PortName = porta;
serialPort.BaudRate = velocidade;
serialPort.Open();
}
public string[] GetPortas()
{
return SerialPort.GetPortNames();
}
public string[] GetVelocidades()
{
return new string[] { "1200", "2400", "4800", "9600", "19200", "38400", "57600", "115200" };
}
void serialPort_DataReceived(object s, SerialDataReceivedEventArgs e)
{
byte[] data = new byte[serialPort.BytesToRead];
serialPort.Read(data, 0, data.Length);
data.ToList().ForEach(b => recievedData.Enqueue(b));
processData();
// like this use LineReceivedEvent or LineReceived
}
private void processData()
{
// Determine if we have a "packet" in the queue
if (recievedData.Count > 50)
{
var packet = Enumerable.Range(0, 50).Select(i => recievedData.Dequeue());
}
}
public void Dispose()
{
if (serialPort != null)
serialPort.Dispose();
}
}
}
Program:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO.Ports;
using TCCExterna.Lib;
namespace TCCExterna
{
public partial class FormPrincipal : Form
{
PortaSerial sp1 = new PortaSerial(); // like this command passed LineReceivedEvent or LineReceived
public delegate void LineReceivedEvent(string line);
public void LineReceived(string line)
{
//What to do with the received line here
}
public FormPrincipal()
{
InitializeComponent();
cmbPortas.Items.AddRange(sp1.GetPortas());
cmbVelocidade.Items.AddRange(sp1.GetVelocidades());
}
}
}

If I got it clearly, what you want is this: (se quiser pode explicar melhor em português, depois a gente traduz pro site).
//delcare an event args clas
public class LineReceivedEventArgs : EventArgs
{
//Data to pass to the event
public string LineData{get; private set;}
public LineReceivedEventArgs(string lineData)
{
this.LineData = lineData
}
}
//declare a delegate
public delegate void LineReceivedEventHandler(object sender, LineReceivedEventArgs Args);
public class PortaSerial //: IDisposable
{
private SerialPort serialPort;
private Queue<byte> recievedData = new Queue<byte>();
//add event to class
public event LineReceivedEventHandler LineReceived;
public PortaSerial()
{
serialPort = new SerialPort();
serialPort.DataReceived += serialPort_DataReceived;
}
public void Abrir(string porta, int velocidade)
{
serialPort.PortName = porta;
serialPort.BaudRate = velocidade;
serialPort.Open();
}
public string[] GetPortas()
{
return SerialPort.GetPortNames();
}
public string[] GetVelocidades()
{
return new string[] { "1200", "2400", "4800", "9600", "19200", "38400", "57600", "115200" };
}
void serialPort_DataReceived(object s, SerialDataReceivedEventArgs e)
{
byte[] data = new byte[serialPort.BytesToRead];
serialPort.Read(data, 0, data.Length);
data.ToList().ForEach(b => recievedData.Enqueue(b));
processData();
//raise event here
if (this.LineReceived != null)
LineReceived(this, new LineReceivedEventArgs("some line data"));
}
private void processData()
{
// Determine if we have a "packet" in the queue
if (recievedData.Count > 50)
{
var packet = Enumerable.Range(0, 50).Select(i => recievedData.Dequeue());
}
}
public void Dispose()
{
if (serialPort != null)
serialPort.Dispose();
}
}
public partial class FormPrincipal : Form
{
PortaSerial sp1 = new PortaSerial(); // like this command passed LineReceivedEvent or LineReceived
// event handler method
void sp1_LineReceived(object sender, LineReceivedEventArgs Args)
{
//do things with line
MessageBox.ShowDialog(Args.LineData);
}
public FormPrincipal()
{
InitializeComponent();
//add handler to event
sp1.LineReceived += new LineReceivedEventHandler(sp1_LineReceived);
cmbPortas.Items.AddRange(sp1.GetPortas());
cmbVelocidade.Items.AddRange(sp1.GetVelocidades());
}
}

BackgroundWorker report progress from external Class?

I have a working solution that reports progress & text to a progress bar and a label on the applications's main form. I have now moved my worker methods to a class to they are accessible across multiple forms etc.
Within the worker methods are BW.ReportProgress() statements that push back the progress and text to the BackgroundWorker in the main form.
To give a better idea here is the file layout:
MainScreen.cs
List repSelected = new List();
XMLandRar xXMLandRar = new XMLandRar();
private void Rarbtn_Click(object sender, EventArgs e)
{
GetReps();
//Run worker
if (!CreateRarBW.IsBusy)
{
CreateRarBW.RunWorkerAsync();
}
}
//Worker
private void CreateRarBW_DoWork(object sender, DoWorkEventArgs e)
{
xXMLandRar.RarFiles(repSelected);
}
//Progress reporting
private void CreateRarBW_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
progBar.Value = e.ProgressPercentage;
Statuslbl.Text = e.UserState.ToString();
}
Then my newly created Class that encompasses all of the worker methods and is to push progress to the main form.
XMLandRar.cs
public class XMLandRar
{
public void RarFiles(List repSelected)
{
int step = 100 / repSelected.Count();
int i = 0;
//Iterate through list and run rar for each
foreach (string rep in repSelected)
{
CreateRarBW.ReportProgress(i, "Raring files for " + rep);
DirectoryExists(rep);
ProcessRunner(rep);
i += step;
CreateRarBW.ReportProgress(i, "Raring files for " + rep);
}
}
}
The problem I am having is that in the XMLandRar class the CreateRarBW is not recognised (obviously) - how can I make a ReportProgress call to the BW in the main screen of the application?

Create an event in your XMLandRar class which you could subscribe to.
This way the XMLandRar class doesn't need to know or care about the UI or progressbar, it only cares about sending a message if anyone would listen. And there can also be more than one subscriber (let's say if you want to report to the background worker and a log, maybe)
Example:
private void Rarbtn_Click(object sender, EventArgs e)
{
GetReps();
//Run worker
if (!CreateRarBW.IsBusy)
{
// This should be done once, maybe in the contructor. Bind to new event.
xXMLandRar.ReportProgress += new EventHandler<XMLandRar.ProgressArgs>(xXMLandRar_ReportProgress);
CreateRarBW.RunWorkerAsync();
}
}
protected void xXMLandRar_ReportProgress(object sender, XMLandRar.ProgressArgs e)
{
// Call the UI backgroundworker
CreateRarBW.ReportProgress(e.Percentage, e.Message);
}
public class XMLandRar
{
// Event handler to bind to for reporting progress
public EventHandler<ProgressArgs> ReportProgress;
// Eventargs to contain information to send to the subscriber
public class ProgressArgs : EventArgs
{
public int Percentage { get; set; }
public string Message { get; set; }
}
public void RarFiles(List repSelected)
{
int step = 100 / repSelected.Count();
int i = 0;
//Iterate through list and run rar for each
foreach (string rep in repSelected)
{
// Report progress if somebody is listening (subscribed)
if (ReportProgress != null)
{
ReportProgress(this, new ProgressArgs { Percentage = i, Message = "Raring files for " + rep });
}
DirectoryExists(rep);
ProcessRunner(rep);
i += step;
// Report progress if somebody is listening (subscribed)
if (ReportProgress != null)
{
ReportProgress(this, new ProgressArgs { Percentage = i, Message = "Raring files for " + rep });
}
}
}
}

The sender object in the DoWork callback is the BackgroundWorker instance which is calling this callback.
This enables to use the instance and add it to your new XMLandRar class.
private void CreateRarBW_DoWork(object sender, DoWorkEventArgs e)
{
var worker = sender as BackgroundWorker.
xXMLandRar.RarFiles(repSelected, worker);
}
XMLandRar.cs
public class XMLandRar
{
public void RarFiles(List repSelected, BackgroundWorker worker)
{
// ...
}
}
Or you set the BackgroundWorkerinstance as a class property to the XMLandRar.
public class XMLandRar
{
protected BackgroundWorker mWorker;
public XMLandRar(BackgroundWorker worker) {
mWorker = BackgroundWorker;
}
public void RarFiles(List repSelected)
{
// Do something with {mWorker}
}
}
Or as mentioned in the comments, using events in the XMLandRar class.
XMLandRar.cs
public class XmlandRarCompletedEventArgs : EventArgs
{
public readonly bool Finished;
public readonly bool Canceled;
public XmlandRarCompletedEventArgs(bool finished)
{
Finished = finished;
Canceled = !finished;
}
}public class OnXmlandRarUpdateEventArgs : EventArgs
{
public readonly int Percentage;
public readonly string Message;
public XmlandRarCompletedEventArgs(int perc) :
this(perc, "") {
}
public XmlandRarCompletedEventArgs(int perc, string message)
{
Percentage = perc;
Message = message;
}
}
public delegate void OnXmlandRarDoWorkHandler(object o);
public delegate void OnXmlandRarUpdateHandler(object o, OnXmlandRarUpdateEventArgs args);
public delegate void OnXmlandRarCompleteHandler(object o, XmlandRarCompletedEventArgs args);
public class XMLandRar
{
public event OnXmlandRarDoWorkHandler OnDoWork;
public event OnXmlandRarUpdateHandler OnUpdate;
public event OnXmlandRarCompletedHandler OnComplete;
public void RarFiles(List repSelected)
{
TriggerDoWork();
int step = 100 / repSelected.Count();
int i = 0;
//Iterate through list and run rar for each
foreach (string rep in repSelected)
{
TriggerUpdate(i, "Raring files for " + rep);
DirectoryExists(rep);
ProcessRunner(rep);
i += step;
TriggerUpdate(i, "Raring files for " + rep);
}
TriggerComplete(true);
}
private void TriggerDoWork()
{
if (OnDoWork != null) {
OnDoWork(this);
}
}
private void TriggerUpdate(perc) {
}
if (OnUpdate != null) {
OnUpdate(this, new OnXmlandRarUpdateEventArgs(perc));
}
private void TriggerUpdate(perc, string message)
{
if (OnUpdate != null) {
OnUpdate(this, new OnXmlandRarUpdateEventArgs(perc, message));
}
}
private void TriggerComplete(bool finished)
{
if (OnComplete != null) {
OnComplete(this, new XmlandRarCompletedEventArgs(finished));
}
}
}
Usage:
private void CreateRarBW_DoWork(object sender, DoWorkEventArgs e)
{
var worker = sender as BackgroundWorker;
// Attach events to class
xXMLandRar.OnDoWork += delegate(object o) {
// ...
};
xXMLandRar.OnUpdate += delegate(object o, OnXmlandRarUpdateEventArgs args) {
// ...
};
xXMLandRar.OnComplete += delegate(object o, XmlandRarCompletedEventArgs args) {
// ...
};
xXMLandRar.RarFiles(repSelected, worker);
}
Hopefully without typos 'cause I'm in the office.

I have fixed errors in the code submitted and cleaned it up... This is a working sample that will help those that maybe couldn't understand the code since it was broken as it was... Although I would like to say that the intent and functionality of the code after it was cleaned up and enhanced is excellent.
This is working code that can get you started in your project for using a backGroundWorker thread for whatever you need.
Just modify this method -
public void RarFiles(List<string> repSelected)
To do whatever work you need. You will also have to modify the arguments you plan on using.. i.e. you may need a DataTable or some custom object...
You can modify the
public class OnXmlandRarUpdateEventArgs : EventArgs
For your needs.. that way when you get a callback.. you can update your main UI form with the changes made to those items..
You may need to do some tweaking.. but you see what i mean..
This is the Form Code.. Don't forget to create a button on the form...
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace ThreadSample
{
public partial class Form1 : Form
{
List<string> repSelected = new List<string>();
XMLandRar xXMLandRar = new XMLandRar();
BackgroundWorker CreateRarBW = new BackgroundWorker();
public Form1()
{
InitializeComponent();
repSelected = new List<string> { "asdf", "asdfsd", "h;ljj" };
CreateRarBW.DoWork += new DoWorkEventHandler(CreateRarBW_DoWork);
}
private void Rarbtn_Click(object sender, EventArgs e)
{
//GetReps();
//Run worker
if (!CreateRarBW.IsBusy)
{
// This should be done once, maybe in the contructor. Bind to new event.
xXMLandRar.ReportProgress += new EventHandler<XMLandRar.ProgressArgs>(xXMLandRar_ReportProgress);
CreateRarBW.RunWorkerAsync();
}
}
protected void xXMLandRar_ReportProgress(object sender, XMLandRar.ProgressArgs e)
{
// Call the UI backgroundworker
CreateRarBW.ReportProgress(e.Percentage, e.Message);
}
//private void CreateRarBW_DoWork(object sender, DoWorkEventArgs e)
//{
// var worker = sender as BackgroundWorker;
// xXMLandRar.RarFiles(repSelected, worker);
//}
private void CreateRarBW_DoWork(object sender, DoWorkEventArgs e)
{
var worker = sender as BackgroundWorker;
// Attach events to class
xXMLandRar.OnDoWork += delegate(object o)
{
// ...
MessageBox.Show("Hey ... Something is going on over there in the classLib .. " + o);
};
xXMLandRar.OnUpdate += delegate(object o, OnXmlandRarUpdateEventArgs args)
{
// ...
//foreach (object oo in args)
{
MessageBox.Show("Hey ... Something is going on over there in the classLib .. Message is " + args.Message + " and Percentage is " + args.Percentage);
}
};
xXMLandRar.OnComplete += delegate(object o, XmlandRarCompletedEventArgs args)
{
MessageBox.Show("Hey ... Something is going on over there in the classLib .. Canceled is " + args.Canceled + " and Finished is " + args.Finished);
// ...
};
xXMLandRar.RarFiles(repSelected);//, worker);
}
}
}
This is the class code. You can just create a class in your current project... Keep in mind that the CreateRarBW object is a BackGroundWorker instance... (Wasn't included above..)
