Javascript window.innerWidth vs. document.body.offsetWidth

var winW = parseInt("630"), winH = parseInt("460");
if (parseInt(navigator.appVersion)>3) {
if (navigator.appName=="Netscape") {
winW = window.innerWidth;
winH = window.innerHeight;
if (navigator.appName.indexOf("Microsoft")!=-1) {
winW = document.body.offsetWidth;
winH = document.body.offsetHeight;

The above code returns the width and height of the browser window regardless if it's Netscape or IE. If the browser is Netscape, we use innerWidth and innerHeight properties of the window object to return the width and height respectively of the browser window. If the browser is IE we use the offsetWidth and offsetHeight properties of the body object of the document object to return the width and height respectively of the browser window.

Javascript document.onmouseover

function GetCoordinates(e){
if (navigator.appName=="Netscape") {
xVal = parseInt(e.pageX);
yVal = parseInt(e.pageY);
if (navigator.appName.indexOf("Microsoft")!=-1) {

This line of code document.onmouseover=GetCoordinates; causes the onmouseover to be fired and calls function GetCoordinates, which is used to keep track of every single mouse movement. Also, the appName property of the javascript navigator object is used to identify the user's browser. If the browser is Netscape, e.pageX and e.pageY return the (X,Y) coordinates of the mouse pointer. Otherwise, event.x and event.y are used to return the (X,Y) coordinates of the mouse pointer in IE.

Javascript document.onclick

function WindowClickEventExplorer(e){
if (navigator.appName=="Netscape") {
if (navigator.appName.indexOf("Microsoft")!=-1) {
var WinEvent = window.event.srcElement.tagName;
if (WinEvent =='INPUT' || WinEvent =='IMG' || WinEvent =='A' || WinEvent =='B' || WinEvent =='SELECT') popIt=0;

The above code captures all the click events within the document inside the current browser and calls function WindowClickEventExplorer at the mouse click. Inside function WindowClickEventExplorer, appName property of javascript navigator object is used to identify the user's browser, which in this case is either Netscape or IE. If the browser is IE, we can use the following line of code window.event.srcElement.tageName to identify the tag name of the source that generates the click event.

Firefox and Thunderbird

My favorite browser and email programs at the moment are Mozilla Firefox (v. 1.5) and Thunderbird (v. 1.0.7). Both of them are free and very compact in size, so you won't have any problem downloading them at all. Now I can use my Gmail email account with Thunderbird. Pretty cool!One of the coolest extensions for Firefox is the Web Developer Toolbar. It adds a menu and a toolbar to the browser with various web developer tools. It is designed for Firefox, Flock and Mozilla, and will run on any platform that these browsers support including Windows, Mac OS X and Linux. If you are a web developer like myself, you should definitely get it.

Got Visual Studio 2005 Installed

I attended a Microsoft Road Show on December 1, 2005 to learn about the new Visual Studio and MS SQL 2005. I also got myself a free copy of the standard edition for both of these products. The Road Show was in Abingdon, Maryland, and it was the very first Microsoft Road Show that I had ever attended. Really cool presentations! I am really looking forward to go to more of these events in the future.

Local.Live.Com From Microsoft

Microsoft started offering a beta of one of its services called Windows Live Local. It combines elements of Microsoft's Virtual Earth technology, MapPoint driving directions and local classified and business searching. You can check it out at local.live.com. It is one of the coolest things I have ever seen. Try putting in your address and see if the Bird's Eye images are availabe. It's awesome!

MS in E-Commerce Program

The degree program requires 36 credits be completed. All students complete an E- commerce core, the breadth requirement, comprised of six courses from four interdisciplinary foundation disciplines totaling 18 credits.
Following completion of these core courses, students take specialized application courses, for a total of 15 credits, in one of six chosen fields of concentration: Information Technology, Management, Health Systems, Public Policy, Enterprise Management, and Law. Students from all concentrations will deepen their theoretical and practical knowledge through courses in the concentration, the depth requirement, building upon a common core of knowledge.

One of the unique features of the degree program is an electronic commerce capstone project course (3 credits), taken by all students at the completion of all their coursework. The capstone project is an interdisciplinary course that reinforces and integrates material covered in core and concentration courses. It allows students to pursue a mixed team- based, practical project related to E-commerce in an identified area of opportunity. This capstone project serves to give students an integrative experience in response to digital age challenges and opportunities. It also allows them to work with other students from a diverse set of backgrounds.

The core is compose of eighteen credits comprising the following three-credit courses:
EC 511 E-commerce Basic IT Infrastructure
EC 512 E-commerce Software Services

Javascript Location Object

The Javascript location object has 3 important properties: href, host, and protocol and 2 methods: replace() and reload()

location.href - returns the current URL
location.host - returns the current Host
location.protocol - returns the protocol used
window.location.href = "http://www.newurl.com" - sends user to "http://www.newurl.com"
window.location.replace("http://www.newurl.com") - sends user to "http://www.newurl.com"
setTimeout("location.reload()",100000) - refreshes the current page every 100 seconds
