Scripting

As you know the usage of JavaScript has been more and more used in web applications over the past years for technologies such as AJAX. JavaScript can accomplish really cool stuff on the client side and make the user interface more interactive and responsive. Just take a look at SharePoint 2010 - that’s some heavy JavaScripts there (a bit to heavy IMHO). So lets assume that you are building some new cool stuff, in SharePoint of course, and why not a Page Component for a contextual Web Part.

Mozilla Links has an article about the Firefox ultimate feature - Performance, in which they compare the JavaScript performance on different web browsers. Firefox 3 beta 4 as some really impressive JavaScript performance and outruns Internet Explorer 7 with about 700%. But the article did not test Internet Explorer 8 beta, which I think should have been there (at least for reference). Since the IE8 team claims the performance is so much better, and my feeling after a few days of IE8 usage says so I had to do some testing on my own.

The Application Templates for Windows SharePoint Services 3.0, also known as the Fab40, is a set of forty different templates that can be used within a SharePoint environment. These templates are good to use as a starter when creating new SharePoint sites or custom solutions and I recommend that you install them into your test or development environment. But the download contains 40 different .wsp and .stp files which has to be installed one at a time; either using STSADM or using the web interface.

Here is a list of cheat sheets for the Windows and .NET platform that I frequently use and I think are of great interest.

The Snap Preview Anywhere (SPA), as I earlier removed from this site, has been updated with some new functionality to make it better for site owners who don’t want their homepages cluttered with previews or users that do not want to see the previews. As a site owner you can now put up an option for your users to turn on or off the SPA: And there is also an option to have the preview to trigger on an icon instead of the whole link:

Finally ASP.NET AJAX 1.0, known as Atlas, is released in a fully supported version. The Download is available at http://ajax.asp.net. Here’s a summary from Scott’s blog: The ASP.NET AJAX 1.0, which is available for free with full Microsoft support, can be extended with the ASP.NET AJAX Control Toolkit - a set of more than 30 controls for ASP.NET. Microsoft also releases the client-side ASP.NET AJAX JavaScript library under the Microsoft Permissive License (Ms-PL) which allows you to modify the library and the server-side code is released under Microsoft Reference License (Ms-RL) so your debugging will be easier.

We have been doing a lot of work, on our product, with dynamic updates of web pages - you know the AJAX stuff. Most of the server side results are returned as XML and are delivered from different Web Services. Since I really like optimizations and like good and nice looking code I have been going back and forth in decision of how to return data to the client; XML or JSON.

The IEBlog announced that the IE Developer Toolbar Beta 3 is available now. It contains some nice updates such as new interface with an icon in the command bar for easy access to the DOM Explorer and finally a great HTML source viewer. Time will also tell if the R-character hijack bug is still left, I have not noticed it yet… Note: You have to uninstall previous betas of the IE Developer Toolbar, otherwise you will have some nice crashes of Internet Explorer when trying to access the toolbar.

Ever wondered what JavaScript closures are? Morris Johns has put togehter a nice introduction to the mysterious closures - JavaScript closures for dummies. Make sure to read it before you do any more JavaScripting. Understanding JavaScript closures will make your JS programming more efficient and you can avoid the dreaded memory leaks in Internet Explorer especially when making home brewed Ajax applications. And of course learning this stuff is fun for us developers…

Here are some small tips when using VBScript CustomActions using WIX.Creating a script CustomActionFirst of all you have to create a CustomAction in your WXS file: <CustomAction Id="Id_Of_ScriptAction" BinaryKey="Id_of_binary" VBScriptCall="Script_Name" /> Id_Of_ScriptAction is a unique Id of your CustomActionID_of_binary is the unique Id of the binary that contains the vbs file.Script_Name is the name of the Sub or Function in your vbs file.
