Use the web browser control comes with .net. Here is a sample code to give you some idea. webBrowser1.Document.GetElementById("fieldname").SetAttribute("value", "foo"); webBrowser1.Document.GetElementById("button").InvokeMember("click");

if you post the code block that giving this error we'd be glad to help. I don't think anyone here have that prediction ability.

You can capture an event like onscroll with this[^] and you can set new scrool position on second treeview by this[^]

Sorry I thought you were trying to send data to database. Now i understood you are trying to refresh grid from database. data changes > trigger that broadcasts/sends a message > client application "listening" > performs a grid refresh is the best way i think

By looking the question that he asked i think this method is adequate for this question. I agree that this is not the best way and not very efficient but anything not mentioned about performance, or other ways that already tried.

I think you ment DataGridView Control by dgv?? If you are using dataadapter object you can easily reflect changes to db. All you need is a timer control, and calling update method of this adapter in Tick event of timer.

This code is for current visitors on site if you implement Session_end event too. If you are trying to count total visitors you must use a database or any kind of data storage

Could you try

    private string GetResponse()
    {

        //read till finding new line, return.

        string strPrev = null;

        string strCurrent = null;

        string strMessage = null;

        NetworkStream ns = default(NetworkStream);

        ns = client.GetStream;//Previously instanced and connected TcpClient

        while (true)
        {

            byte\[\] buffer = new byte\[1\];
            //read by 1 byte 1 byte

            ns.Read(buffer, 0, buffer.Length);

            strCurrent = System.Text.Encoding.GetEncoding(1254).GetString(buffer);

            strMessage = strMessage + strCurrent;

            if (strCurrent == @"\\r" && strPrev == @"\\n")
            {

                break; // TODO: might not be correct. Was : Exit While
            }


            strPrev = strCurrent;
        }


        return strMessage;
    }

    private void SendMessage(string str)
    {

        str = str + "\\r\\n";
        //Controlchars.CrLf '10+13

        byte\[\] buffer = System.Text.Encoding.GetEncoding(1254).GetBytes(str);

        NetworkStream ns = client.GetStream;


        ns.Write(buffer, 0, buffer.Length);
    }

Everything seems ok. Could you pls send the SendCommandSynchronous method

As an other way you can create office open xml file, but this way is much harder. For more information you can visit http://msdn.microsoft.com/en-us/library/aa338205.aspx[^]

You can use word interop to write xml file's content to word document. If you google 'how to create document with word interop' you'll find tons of examples.

If you are talking about Exchange server there is a web service of Exchange 2007 sp2, if you are talking about pop3 mail server you can try connecting to server by simulating telnet from your application and delete mail.

this[^] might help

Seems like changing the connectionstring is enough to change database. Have you changed your connectionstring to connect another database. Is it possible for you ti share the code.

In service properties at Log On tab "Allow Service to interact with desktop" should be checked.

Try setting commands timeout property to a higher value

You can user PerformanceCounter component by setting CategoryName property to Network Interface and after selecting appropriate counter.

You can use the code below, but it may need some performance improvements

    List<FileInfo> fi = new List<FileInfo>();
    ListBox l = new ListBox();
    private void Form1\_Load(object sender, EventArgs e)
    {


    }
    private void GetSubFoldersAndFiles(string path)
    {

        

        foreach (string d in Directory.GetDirectories(path))
        {
            try
            {
                GetSubFoldersAndFiles(d);
            }
            catch (Exception)
            {


            }

        }
        foreach (string f in Directory.GetFiles(path))
        {
            fi.Add(new FileInfo(f));
            
        }
    }

    private void Form1\_Shown(object sender, EventArgs e)
    {
        l.Dock = DockStyle.Fill;
        this.Controls.Add(l);


        foreach (DriveInfo di in DriveInfo.GetDrives())
        {
            if (di.IsReady)
            {
                GetSubFoldersAndFiles(di.RootDirectory.FullName);
            }
        }
        var a = (from s in fi orderby s.Length descending select s);
        l.DataSource = a.ToList();
    }

Try this[^] PLease inform if any errors

For higher performance you can use Convert.ToInt32
