+\subsection{Listctrl sample}\label{samplelistctrl}
+
+This sample shows \helpref{wxListCtrl}{wxlistctrl} control. Different modes
+supported by the control (list, icons, small icons, report) may be chosen from
+the menu.
+
+The sample also provides some timings for adding/deleting/sorting a lot of
+(several thousands) controls into the control.
+
+\subsection{Sockets sample}\label{samplesockets}
+
+The sockets sample demonstrates how to use the communication facilities
+provided by \helpref{wxSocket}{wxsocketbase}. There are two different
+applications in this sample: a server, which is implemented using a
+\helpref{wxSocketServer}{wxsocketserver} object, and a client, which
+is implemented as a \helpref{wxSocketClient}{wxsocketclient}.
+
+The server binds to the local address, using TCP port number 3000,
+sets up an event handler to be notified of incoming connection requests
+({\bf wxSOCKET\_CONNECTION} events), and stands there, waiting for clients
+({\it listening} in the socket parlance). For each accepted connection,
+a new \helpref{wxSocketBase}{wxsocketbase} object is created. These
+socket objects are independent from the server that created them, so
+they set up their own event handler, and then request to be notified
+of {\bf wxSOCKET\_INPUT} (incoming data) or {\bf wxSOCKET\_LOST}
+(connection closed at the remote end) events. In the sample, the event
+handler is the same for all connections; to find out which socket the
+event is addressed to, the \helpref{GetSocket}{wxsocketeventgetsocket}
+function is used.
+
+Although it might take some time to get used to the event-oriented
+system upon which wxSocket is built, the benefits are many. See, for
+example, that the server application, while being single-threaded
+(and of course without using fork() or ugly select() loops) can handle
+an arbitrary number of connections.
+
+The client starts up unconnected, so you can use the Connect... option
+to specify the address of the server you are going to connect to (the
+TCP port number is hard-coded as 3000). Once connected, a number of
+tests are possible. Currently, three tests are implemented. They show
+how to use the basic IO calls in \helpref{wxSocketBase}{wxsocketbase},
+such as \helpref{Read}{wxsocketbaseread}, \helpref{Write}{wxsocketbasewrite},
+\helpref{ReadMsg}{wxsocketbasereadmsg} and \helpref{WriteMsg}{wxsocketbasewritemsg},
+and how to set up the correct IO flags depending on what you are going to
+do. See the comments in the code for more information. Note that because
+both clients and connection objects in the server set up an event handler
+to catch {\bf wxSOCKET\_LOST} events, each one is immediately notified
+if the other end closes the connection.
+
+There is also an URL test which shows how to use the \helpref{wxURL}{wxurl}
+class to fetch data from a given URL.
+
+The sockets sample is work in progress. Some things to do:
+
+\begin{itemize}\itemsep=0pt
+\item More tests for basic socket functionality.
+\item More tests for protocol classes (wxProtocol and its descendants).
+\item Tests for the recently added (and still in alpha stage) datagram sockets.
+\item New samples which actually do something useful (suggestions accepted).
+\end{itemize}
+
+\subsection{Statbar sample}\label{samplestatbar}
+
+This sample shows how to create and use wxStatusBar. Although most of the
+samples have a statusbar, they usually only create a default one and only
+do it once.
+
+Here you can see how to recreate the statusbar (with possibly different number
+of fields) and how to use it to show icons/bitmaps and/or put arbitrary
+controls into it.
