问题 I'm trying to create a Silverlight application (for the first time) that involves parsing XML from a site and displaying information. To do this I am using Visual Studio 2008 on Windows XP Service Pack 3. I also have .NET Framework 3.5 SP1 installed. My problem is that no XML-parser I have seen on the internet works.

I ofcourse could also try to write my own parser

问题 I have a page that contains a WebBrowser control that is frequently updating content. I am using a black background, but the default color before loading content of the WebBrowser is white. I could change it by loading a small HTML string with the background set to black but there is still a period of time when the WebBrowser appears as white so there is a sort of a flickering effect happening. My question is this: is there any way to change the color of the underlying control of the

问题 Okay Stackers, I've spent a good couple of hours on this question, and I want to know if anybody has a definitive answer. For all the research I've done, I can't find ANY difference between .Register and .RegisterAttached in Silverlight . Now, before you jump the gun and tell me that .RegisterAttached is used for attaching a DP to another class, try implementing an Attached Dependency Property using DependencyProperty.Register() .

问题 I'm trying to include a text file that contains some static data that I need to read in when the app starts up. I've added the file and marked the Build Action to "Resource" but I'm unsure of how to actually read it in as a stream.
