In recently i want to delete all the screens in display stack.  I used following code to do it.   int screenCount = UiApplication.getUiApplication().getScreenCount() ; for (int i = 0; i < screenCount; i++) { Screen screen = UiApplication.getUiApplication().getActiveScreen() ; UiApplication.getUiApplication().popScreen(screen); }

private void ConnectToServer() { using ( TcpClient tc = new TcpClient ( "127.0.0.1" , 12)) { NetworkStream ns = tc.GetStream(); StreamWriter sw = new StreamWriter (ns); StreamReader sr = new StreamReader (ns); sw.WriteLine( "test message" ); sw.Flush(); System. Console .WriteLine(sr.ReadLine()); } } This code can be used to connect to a server using a socket and send a simple message to it.

The code below illustrate how to listen to Tcp/Ip port for incoming stream.  The code can use to listen any port but some times you may encountered an exception ( Refer ).   private void Run_Server() { // Listen to our own port 80 (HTTP protocol port). IPAddress localAddr = IPAddress .Parse( "127.0.0.1" ); TcpListener listen = new TcpListener (localAddr, 80); try { // Start listening listen.Start(); Byte [] bytes = new byte [256]; TcpClient client = listen.AcceptTcpClient(); // This waits until we getting a connection NetworkStream stream = client.GetStream(); int i; String data = null ; while (stream.DataAvailable) { i = stream.Read(bytes, 0, bytes.Length); data = System.Text. Encoding .ASCII.GetString(bytes, 0, i); txtMessages.Text += data.ToString(); } client.Close(); } catch ( SocketException exceptionError) ...

// Listen to our own port 80 (HTTP protocol port). IPAddress localAddr = IPAddress .Parse( "127.0.0.1" ); TcpListener listen = new TcpListener (localAddr, 80); This exception occurred me in Vista because of Port. This exception rise some well-known ports thus using other port (Ex:- 12 , 8008) you may resolve this.

Some times you might want to print the report Column wise so this is simple. what you have to do is go to Section Expert and –> Details and check the Format with Multiple Columns. then Layout tab will appear . then  configure the relevant values. after pressing ok , you can see your detail section is resized. Now you are done.

This is a common error when you are binding data to the data grid. you can correct it as giving following code to the  PageIndexChanging event. protected void gridView_PageIndexChanging( object sender, GridViewPageEventArgs e) { gridView.PageIndex = e.NewPageIndex; gridView.DataBind(); }
