Overflow PRE tag (HTML & CSS)

Text doesn't wrap with the <pre> tag, so you need to scroll horizontally if there is a lot of text on one line: 
Nulla neque diam, accumsan nec, egestas non, facilisis sed, wisi.    Donec lacinia vestibulum arcu. Suspendisse ligula. Donec tortor. Maecenas pharetra eros at odio.
	Morbi feugiat tempus orci. Cras vitae tellus. Sed congue nonummy magna. In sed neque id nisl tempus congue.
Duis varius egestas tellus. Suspendisse potenti. Nunc rhoncus, eros eget malesuada rhoncus, mi purus pharetra eros, sit amet porta lectus tortor ac erat.
In hac habitasse platea dictumst.
However, if you wrap it as follows <pre style="overflow: auto; width: 100%">Text</pre> it adds scroll bars when needed: 
Nulla neque diam, accumsan nec, egestas non, facilisis sed, wisi.    Donec lacinia vestibulum arcu. Suspendisse ligula. Donec tortor. Maecenas pharetra eros at odio.
	Morbi feugiat tempus orci. Cras vitae tellus. Sed congue nonummy magna. In sed neque id nisl tempus congue.
Duis varius egestas tellus. Suspendisse potenti. Nunc rhoncus, eros eget malesuada rhoncus, mi purus pharetra eros, sit amet porta lectus tortor ac erat.
In hac habitasse platea dictumst.
width and overflow has to be defined, else it will not work. It also does not work particulary well when there are not many lines of text (scroll bars get in the way [at least 3 line breaks recommended]): 
Nulla neque diam, accumsan nec, egestas non, facilisis sed, wisi.    Donec lacinia vestibulum arcu. Suspendisse ligula. Donec tortor. Maecenas pharetra eros at odio.

iTextSharp: Generating a Basic PDF file (ASP.NET/C#)

iTextSharp is free library for .NET that allows you to create PDF documents. It can be used to dynamically create PDF's which can be streamed to the user. As there is no HTML being sent to the user, a WebHandler (ashx file) is a more appropriate way to generate your PDF than an aspx page. Download itextsharp-3.0.10-dll.zip (latest version as of 08 Feb 2006) and save the dll in the archive to your websites bin directory. Here is a basic sample of creating a PDF (more complex samples may follow in future posts). BasicPDF.ashx <%@ WebHandler Language="C#" Class="MyNamespace.BasicPDF" %> using System; using System.IO; using System.Web; using iTextSharp.text; using iTextSharp.text.pdf; namespace MyNamespace { public class BasicPDF: IHttpHandler { public bool IsReusable { get { return true; } } /// <summary> /// Font used for any hyperlinks added to the PDF /// </summary> private Font LinkFont { get ...

Popup Window Countdown (JavaScript)

This code opens a new popup window that contains a timer that counts down, then closes the window when it reaches 0. Will not work if user has a popup blocker blocking the page. <html> <head> <title>Popup Timer</title> <script language="JavaScript" type="text/JavaScript"> // popup window var var popup; // At what number shall the countdown counter start? CounterStart = 10; // This function CustomAction() can be modified to do // whatever you want done every second. function CustomAction() { popup.document.timer.timeleft.value = CounterStart; } // end of function CustomAction() // end of JavaScript customization function Decrement() { CounterStart--; CustomAction(); if(CounterStart <= 0) { popup.close(); alert('Timer reached 0'); } else { setTimeout('Decrement()',1000); } } function StartTheCounter() { openPopup(120,100); setTimeout('Decrement()',1000); } f...
