Solution 1

1) create your your WinForm - application with 1 Button, a ListBox and a Backgroundworker
2) Add the Button_click-Event, the BackgroundWorker1DoWork-Event, the BackgroundWorker1RunWorkerCompleted-Event and the BackgroundWorker1ProgressChanged-Event

3) add this code:

C#

void Button1Click(object sender, EventArgs e)
{
    backgroundWorker1.RunWorkerAsync();
}
void BackgroundWorker1DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
{
    int Port = 8088;
    TcpListener server = new TcpListener(IPAddress.Any, Port);
    server.Start();
    byte[] bytes = new byte[1024];
    string data;
    //Console.Write("Waiting for Client connection ");
    backgroundWorker1.ReportProgress(25);

    TcpClient client = server.AcceptTcpClient();
    //Console.WriteLine("\n Client Connected");
    backgroundWorker1.ReportProgress(50);
    NetworkStream stream = client.GetStream();
    int i;
    i = stream.Read(bytes, 0, bytes.Length);
    data = Encoding.UTF8.GetString(bytes, 0, i);
    data = data.Substring(2, data.Length - 2);

    client.Close();server.Close();
    e.Result=data;
}
void BackgroundWorker1RunWorkerCompleted(object sender, System.ComponentModel.RunWorkerCompletedEventArgs e)
{
    listBox1.Items.Add(String.Format("Data Received: {0}", (string)e.Result));
}
void BackgroundWorker1ProgressChanged(object sender, System.ComponentModel.ProgressChangedEventArgs e)
{
    switch (e.ProgressPercentage) {
        case 25:
            listBox1.Items.Add("Waiting for Client connection ");
            break;
        case 50:
            listBox1.Items.Add("Client Connected");
            break;
    }
}

You might want to also hook the form closing event and call backgroundWorker1.Abort so that the app doesn't hang when the user closes it.

Florian Braun 16-Apr-15 2:08am

right, good Idea

Srikanth59 16-Apr-15 2:32am

This is good idea but am getting errors
1. void Button1Click(object sender, EventArgs e)
{
backgroundWorker1.DoWork();
}
Error is The Event ComponentModel.BackgroundWorker.DoWork can appear on the left hand side of += or -=
2.void BackgroundWorker1RunWorkerCompleted(object sender, System.ComponentModel.RunWorkerCompletedEventArgs e)
{
listBox1.Items.Add("Data Received :{0}", (string)e.Result);
}
}

Error is NO Overload for Method Add takes 2 arguments.

also you need to set the property of the backgroundworker "WorkerReportsProgress" and "WorkerSUpportsCancellation" both to true

Srikanth59 16-Apr-15 3:33am

yes i set both the property to true but am getting some more errors in the listbox
An exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll but was not handled in user code
switch (e.ProgressPercentage)
{
case 25:
listBox1.Items.Add("Waiting for Client connection ");
break;
case 50:
listBox1.Items.Add("Client Connected");
break;

Florian Braun 16-Apr-15 3:38am

there must be something missing in your application. I tested the whole code and it worked fine for me

Florian Braun 16-Apr-15 3:04am

oh ok, sorry... found the errors... changend my solution

Srikanth59 16-Apr-15 3:34am

Could you solve this errors

Florian Braun 16-Apr-15 3:37am

i changed some bits in my solution. its not Backgroundworker1.DoWork() but .RunWorkerAsync(). And the second Error was fixed with STring.Format() inside listbox1.Items.Add(). you can find both changes in my solution. I changed it there.

Srikanth59 16-Apr-15 3:57am

okay i got but am getting some more errors in the listbox
An exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll but was not handled in user code
switch (e.ProgressPercentage)
{
case 25:
listBox1.Items.Add("Waiting for Client connection ");
break;
case 50:
listBox1.Items.Add("Client Connected");
break;

Florian Braun 16-Apr-15 4:07am

hard so say whats wrong. i tested this code and it worked...

Srikanth59 16-Apr-15 4:13am

thank you... if possible could you correct errors

Florian Braun 16-Apr-15 4:15am

as is said, after i changed my code like i did in my answer i could run it withou any errors or exceptions. I don't know why you still get that exception of type 'System.InvalidOperationException' but i'd guess that in your code something is missing which i did in mine or vice versa.

Srikanth59 16-Apr-15 5:16am

i got it, I added Invoke code in that listbox

this.Invoke(new MethodInvoker(delegate()
{
switch (e.ProgressPercentage)
{
case 25:
listBox1.Items.Add("Waiting for Client connection ");
break;
case 50:
listBox1.Items.Add("Client Connected");
break;
}

Srikanth59 16-Apr-15 5:17am

but am unable to close the server sometimes it hangs the application.
server.Close() is not working..

Florian Braun 16-Apr-15 5:20am

you are vey welcome... strange that you need this invoke... as long as it works.. maybe you'll find the reason for that one day...
