Yahoo! User Interface Library and Design Pattern Library

Yahoo! User Interface Library is a JavaScript library (under the open source BSD license) that can be used to make a site more interactive. It is comprised of 'Core Utilities' and 'UI Controls'.

Core Utilities

  • Animation
  • Connection Manager (XMLHttpRequest / AJAX)
  • DOM (manipulating the elements (style, coordinates) in a loaded web page)
  • Drag and Drop
  • Event (adding them to existing elements on a page)

UI Controls

  • Calendar
  • Slider
  • TreeView

Yahoo! Design Pattern Library is a set of solutions to common problems (breadcrumbs, autocomplete, drag/drop, pagination etc). There is no code, but it does demonstrate the solutions Yahoo uses for its sites.

They also have a blog about it: Yahoo! User Interface Blog.

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
