Q: What is the difference between XHTML and DHTML? A: XHTML is a more structured version of HTML, which sits nicely with the XML structure. XML (eXtensible Markup Language) is used to identify the data contents (i.e. name, address, phone, etc.) XML can then be used with XSLT to render the contents in different ways. Couple XML with HTML and you have a XHTML. DHTML (Dynamic Hypertext Markup Language) is a Microsoft derived term. It is a combination of HTML, CSS, and JavaScript. It all works via the DOM (Document Object Model). This is a method of referencing objects within a document so that you can manipulate them through JavaScript.

Earlier this month, Microsoft released 12 patches for fixing 23 vulnerabilities. Of those 12 patches, MS06-040 and MS06-042 were discovered to have memory bugs causing programs to crash. MS06-040 affects programs that use very large chunks of memory on some versions of Windows. According to Microsoft, programs such as Microsoft Navision 3.7, which require allocations of more than 1GB of memory, can crash after the update is installed. Most Windows systems do not experience the bug, but Microsoft Windows Server 2003 and the 64-bit version of Windows XP Professional Edition are affected. Microsoft's hotfix for this problem can be downloaded from their site . More troublesome has been the MS06-042 update for Internet Explorer, which has caused browser crashes while using Web-based applications such as PeopleSoft, Siebel and Unicenter. Microsoft issued a hotfix for this update earlier in the week and is promising to reissue the buggy update next Tuesday. For more information on thi...

Q: What is "Atlas"? A: "Atlas" is the code name for a set of ASP.Net technologies used to add Ajax (Asynchronous JavaScript And XML) support to ASP.NET. It consists of a client-side script framework, server controls, and more. In other words, Atlas is Microsoft's implementation of Ajax. This new Web development technology from Microsoft integrates client script libraries with the ASP.NET 2.0 server-based development framework. In addition, "Atlas" offers you the same type of development platform for client-based Web pages that ASP.NET offers for server-based pages. And because "Atlas" is an extension of ASP.NET, it is fully integrated with server-based services. "Atlas" makes it possible to easily take advantage of AJAX techniques on the Web and enables you to create ASP.NET pages with a rich, responsive UI and server communication. However, "Atlas" isn’t just for ASP.NET. You can take advantage of the rich client framew...

I found an article on keith Ritchie's blog detailing how to use SPUserUtil to synchronize SharePoint user Display Names and Email addresses with the information in Active Directory SPUserUtil will mean either WSSUserUtil or SPSUserUtil respectively (WSSUserUtil is used to administer Windows SharePoint Sites on a standalone WSS Farm/Virtual server OR Windows SharePoint sites in the same virtual server of a SharePoint Portal Server 2003 site.)

As discussed in our last meeting, web applications can be built to handle both PC browsers and mobile browsers. To do so, the application needs to detect if the browser is a mobile device and redirect the application to a page designed to display UI adequate for the smaller mobile browser. Detecting the browser is done using the following code sample, and it's typically placed in the Page_Load() of the login.aspx or default.aspx Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Try If Not IsPostBack Then If Request.Browser.IsMobileDevice = True Then Response.Redirect("mobile/login.aspx") End If End If Catch ex As Exception ProcessEx(ex) End Try End Sub
