A hash array (aka dictionary) stores a value in memory that is accessible using a key name. I like using hash arrays to store the key/value pairs found in an URL’s query string. JavaScript comes with a standard indexed array but lacks a hash array. Lucky for us creating a hash array is a very simple and useful exercise in JavaScript.

Coding On a Thread and a Prayer
Threading is a powerful concept growing more critical for application development. Modern computers aren’t always faster than computers from even four years ago. Instead, computer manufacturers focus on packing more CPU’s into a smaller package with the idea that workload split across many chips will run on a magnitude faster than the fastest chip. This performance gain can only be realized when an application is intentionally designed to take advantage of the multiple cores. As you begin working with threads, however, you will quickly realize that you must design your applications on a thread and a prayer!
Today’s article will be a little different from previous articles I have written. Instead of explaining what a thread is and how to use it I will be reviewing the various issues I have encountered while working with multiple threads and how I have resolved those issues. I trust that today’s article will help others who have encountered these same issues while developing multi-threaded applications.

JavaScript Chaining Made Fun!
The chain pattern allows several actions to be executed within a single line of concurrent code. jQuery’s use of chaining has popularized the concept so that the masses now prefer chaining their method calls. Creating an application that supports chaining can be cumbersome. This article will demonstrate how to add chaining functionality to any JavaScript class without modifying any code in the class you want to upgrade to support the chaining pattern.

Create Scrollable Table with CSS and jQuery
In the post, CSS Table Scrollbar with Fixed Headers, we explored a fairly simply way to create tables with scrollbars using CSS. Today we take it up a notch using jQuery to eliminate several limitations introduced with the pure CSS approach.

CSS Table Scrollbar with Fixed Header and Footer
I am truly surprised that CSS3 failed to include scrollbar support for the TBody tag. However, with a bit of finagling we can create a great looking scrollable table with the help of a single div tag!

JavaScript Characters
While reviewing the C language I was reminded of the cType.h library. The cType library is a Character Type helper class. After short consideration I thought it might be helpful to have an equivalent in JavaScript.

Image Fading Effects
A commonly requested feature for web pages is to cycle thru a list of images fading each image over the previous image. In today’s post we will use JQuery to provide this capability with the added benefit that once created we can control the list of images to cycle with HTML image tags and no JavaScript changes.

AD Query: Putting it All Together
In the previous seven posts we learned how to construct an Active Directory Data Access Layer. In today’s post we will use the AD DAL to create an Active Directory Query tool. AD Query will allow us to select, insert, update and delete objects in Active Directory with a familiar intuitive interface. Best of all, AD Query will demonstrate just how easy it is to work with Active Directory now that we have implemented the DataBase Access Layer.
