\section{wxWindows samples}\label{samples}
The next most useful sample is probably the \helpref{controls}{samplecontrols}
one which shows many of wxWindows standard controls, such as buttons,
-listboxes, checkboxes, comboboxes e.t.c.
+listboxes, checkboxes, comboboxes etc.
Other, more complicated controls, have their own samples. In this category you
may find the following samples showing the corresponding controls:
This sample demonstrates the use of the \helpref{wxCheckListBox}{wxchecklistbox}
class intercepting check, select and double click events. It also tests the

+from it or inserting new once (these functions are actually implemented in
the parent class \helpref{wxListBox}{wxlistbox} so the sample tests that class
as well). The layout of the dialog is created using a \helpref{wxBoxSizer}{wxboxsizer}
demonstrating a simple dynamic layout.
\subsection{Config sample}\label{sampleconfig}
This sample demonstrates the \helpref{wxConfig}{wxconfigbase} classes in a platform
-indepedent way, i.e. it uses text based files to store a given configuration under

Unix and uses the Registry under Windows.
See \helpref{wxConfig overview}{wxconfigoverview} for the descriptions of all
modification in terms of colour and font as well as the possibility to change
the controls programmatically, such as adding item to a list box etc. Apart
from that, the sample uses a \helpref{wxNotebook}{wxnotebook} and tests most

\subsection{Database sample}\label{sampledb}
The database sample is a small test program showing how to use the ODBC

+\subsection{Dialup sample}\label{sampledialup}
+
+This sample shows \helpref{wxDialUpManager}{wxdialupmanager}
+class. It displays in the status bar the information gathered through itsi
+nterface: in particular, the current connection status (online or offline) and
+whether the connection is permanent (in which case a string `LAN' appears in
+the thrid status bar field - but note that you may have be on a LAN not
+connected to the Internet, in which case you will not see this) or not.
+
+Using the menu entries, you may also dial or hang up the line if you have a
+modem attached and (this only makes sense for Windows) list the available
+connections.
\subsection{Dynamic sample}\label{sampledynamic}
should be used whenever it is not known at compile time, which control
will receive which event or which controls are actually going to be in
a dialog or frame. This is most typically the case for any scripting

+The event sample demonstrates various features of the wxWindows events. It
+shows using dynamic events and connecting/disconnecting the event handlers
+during the run time and also using
+\helpref{PushEventHandler()}{wxwindowpusheventhandler} and
+\helpref{PopEventHandler()}{wxwindowpopeventhandler}.

+It replaces the old dynamic sample.

\subsection{Exec sample}\label{sampleexec}
The exec sample demonstrates the \helpref{wxExecute}{wxexecute} and
external programs and the sample shows how to do this synchronously (waiting
until the program terminates) or asynchronously (notification will come later).
+It also shows how to capture the output of the child process in both
+synchronous and asynchronous cases and how to kill the processes with
+\helpref{wxProcess::Kill}{wxprocesskill} and test for their existence with

flicker on screen.
+\subsection{Rotate sample}\label{samplerotate}
+
+This is a simple example which demonstrates how to rotate an image with

+be done without interpolation (left mouse button) which will be faster,
+or with interpolation (right mouse button) which is slower but gives
+better results.

\subsection{Font sample}\label{samplefont}
The font sample demonstrates \helpref{wxFont}{wxfont},

The image sample demonstrates the use of the \helpref{wxImage}{wximage} class
and shows how to download images in a variety of formats, currently PNG, GIF,

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 as a
-\helpref{wxSocketServer}{wxsocketserver} object, and a client, which is
-implemented with \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} event), and stands there, waiting (listening
-in the socket parlance) for clients. For each incoming client, a new
-\helpref{wxSocketBase}{wxsocketbase} object is created, which represents
-the connection. Connections are independent from the server that created
-them, so they set up their own event handler, and stay awaiting for
-{\bf wxSOCKET\_INPUT} (incoming data) or {\bf wxSOCKET\_LOST} (connection
-closed at the remote end) events. This event handler is the same for all
-connections, and demonstrates how to determine which socket the event
-is addressed to by using the \helpref{Socket}{wxsocketeventsocket} function

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

tests are possible. Currently, three tests are implemented. They show
