Geeks With Blogs

Welcome to my blog.
Here's what we've got on the menu today:

Lorin Thwaits A geek says what? ASP.NET
Interesting Type difference in .NET 4.0 when using DataBinding

Consider this common construct that you and I have thrown into ASPX pages for years now:

<%# DataBinder.Eval (Container.DataItem, "EmployeeID") %>

In .NET 3.5.1 and older it returns -- tada -- a string.  No mystery there.  But in .NET 4.0 it returns the same type as the underlying data type -- which in this case for me was a nullable int.  Interesting, no?

.NET Framework 4.0 mysteriously loses track of System.EnterpriseServices
The GAC in .NET 4.0 is cut into two parts now -- one half for .NET Framework 2.0 stuff, and the other for v4.0 stuff. When compiling any project, targeting .NET 2.0, 3.5, or what have you, this annoying error may pop up: Could not load file or assembly 'System.EnterpriseServices, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d5... or one of its dependencies. The system cannot find the file specified. If you are working on a 32-bit system then open a run box and perform this copy command: ......

Scott Guthrie's visit to Phoenix is tomorrow
Can't believe how fast the time has flown leading up to this big event. I've been so busy with all the details of getting a huge screen rented, insurance lined up, advertising in place, and more. What a blitz. We were lucky to be able to rent a really nice theater in Arizona, Symphony Hall in the downtown. Now it's just about showtime. If you're in the area and haven't signed up for the event yet then take a look: It's worth taking a sick day at work to come and join in ......

Microsoft brought FPSE back. Will VS2003 work in Vista now?
Some Sharepoint and Front Page folks will no doubt be rejoicing over a beta that was quietly released last Tuesday afternoon. Front Page Server Extensions are now available for Vista and Longorn Server. I thought that perhaps this could open the door to developing ASP.NET 1.1 apps on Vista using Visual Studio 2003, so I decided to do a quick test. You see, VS2005 is very versatile as to how it can open webs, but when Visual Studio 2003 opens a web site, it can only use FPSE. And the lack of FPSE ......

MIX keynote is rockin'
It's a great keynote going on this morning out here at the Venetian, learning about the newest of the new from Microsoft. The new beta bits for Silverlight 1.0 are now available for download, with the RTM is coming this summer. And surronding Silverlight is also the announcement of the featureset to be included in Silverlight 1.1. For that Laurent already mentioned some of the great news. Especially important is that a scaled-down version of .NET will be included in that v1.1 release. We've been ......

Resolving the "Sys is undefined" error in ASP.NET AJAX RTM under IIS 7
A plea out to all those who are using ASP.NET AJAX with sites on IIS7, either under Vista or Longhorn Server: I've been battling a strange issue with ASP.NET AJAX on IIS 7 running under Vista. It's a site that was upgraded from RC1 to RTM, and works great under IIS 6. Have troubleshot it enough under IIS 7 to determine that if the AppPool has the Managed Pipeline Mode set to "Integrated", it fails, and if it's set to "Classic", it works perfectly. The error I'm getting is one that was common during ......

Comparing Dreamweaver and Visual Studio
Dreamweaver has always offered a compelling environment to develop HTML-centric web pages, with some server-side tricks thrown in for good measure. Historically Visual Studio has offered the opposite, great server-side but a bit light on the client-side code. Visual Studio 2005 brought many enhancements that close the gap. A month ago a friend and I finished a project and submitted it to Microsoft that compares the experience between those two. So if you ever wanted to see how things are done in ......
