Firefox 3.7 pre-release 4 still not pass Acid3 test, but getting close

As shown in my last post, Firefox 3.6.2 didn’t pass the Acid3 Test with a score 94/100, 6 points away from passing the test.

Sending email with Visual Studio 2008 in Windows 7 by using Free SMTP Server

You may already know that Microsoft dropped SMTP in client OS since Windows Vista, so apparently Windows 7 will not have SMTP either. If you need a SMTP on your local machine to test and debug your mail function as I do, you can install a free third-party SMTP server called Free SMTP Server. The installation is very straight forward and you don’t need to do any customization. In your application, just use “localhost” as […]

ASP.NET tooltip alternative: Cool DHTML Tooltip II – Part 3

In Part 1 and Part 2, I talked about how to use Cool DHTML Tooltip II to replace ASP.NET built-in tooltip for better user experience.

ASP.NET tooltip alternative: Cool DHTML Tooltip II – Part 1

ASP.NET built-in tooltip is easy to implement, but it has many limitations, for example, you can’t control the duration of the tooltip, you can’t change the style of the tooltip, you can’t display complicated contents in it, etc. That is why I usually don’t use ASP.NET tooltip but use Cool DHTML Tooltip from Dynamic Drive (www.dynamicdrive.com). There are two versions of Cool DHTML Tooltip and the basic difference is that the second version (Cool DHTML […]

Scroll to the top of an AJAX page upon UpdatePanel postback

By default, when an UpdatePanel is refreshed upon postbacks, the navigation position of the page will not change because the postback is only a partial postback. It is a nice behavior in most cases, but in some cases, it can be very annoying. For instance, if you have a Wizard control defined in an UpdatePanel for user data entry, and if the form is very long, then you will need to scroll to the bottom […]
