Windows Forms Receive and Display Data Code Example

The following example demonstrates receiving data in a Windows Forms environment. Data is read asynchronously, as it is available, without blocking the UI. The data is marshaled to the UI thread and written to the display.

private void button1_Click(object sender, EventArgs e)
    //Receive data on a worker thread
    telnet1.Start(receiveData, null);

private void receiveData(object notUsed)
    //Receive data when it is sent by the remote host
    //Marshal it to the UI for display
    byte[] buffer = new byte[1024];
    while (telnet1.State != ConnectionState.Closed)
        telnet1.Marshal(telnet1.Read(buffer, 0, 1024), ""null);

private void telnet1_Data(object sender, DataEventArgs e)
    //Whenever data is received, display it
    if (e.Data != null) vt1.Write(e.Data.Buffer, 0, e.Data.Count);
