+<h1>Sample: Hangman Game</h1>
+<p>
+Having seen the simple "Hello World" application, we now build a more complex application called "Hangman Game". In this game, the player is asked to guess a word, a letter at a time. If he guesses a letter right, the letter will be shown in the word. The player can continue to guess as long as the number of his misses is within a prespecified bound. The player wins the game if he finds out the word within the miss bound, or he loses.

+<p>
+To facilitate the building of this game, we show the state transition diagram of the gaming process in the following,

+<h1>Sample: Hello World</h1>
+<p>
+"Hello World" is the simplest <i>interactive</i> PRADO application that you can build. It displays to end-users a page with a submit button whose caption is <i>Click Me</i>. When the user clicks on the button, the button changes the caption to <i>Hello World</i>.
+</p>
+<p>
+There are many approaches that can achieve the above goal. One can submit the page to the server, examine the POST variable, and generate a new page with the button caption updated. Or one can simply use JavaScript to update the button caption upon its <i>onclick</i> event.
+</p>
+<p>
+PRADO promotes component-based and event-driven Web programming. The button is represented by a <i>TButton</i> object. It encapsulates the button caption as the <i>Text</i> property and associates the user button click action with a server-side <i>Click</i> event. Therefore, the "Hello World" task can be handled intuitively and easily. One simply needs to attach a function to the button's <i>Click</i> event. Within the function, the button's <i>Text</i> property is modified as "Hello World". The following diagram shows the above sequence,
+</p>
+<img src="<%~HelloWorld/sequence.gif%>" />
+<p>
+The code that a developer needs to write is merely the following event handler function, where <code>$sender</code> refers to the button object.
+</p>
+<pre class="source">
+public function buttonClicked($sender,$param)
+{
+ $sender->Text="Hello World";
+}
+</pre>
