Since the initial port of the SharpZipLib library I wasn't able to invest any more time in the development of the library.A while ago I was contacted by Sky Sanders who offered to do some further development on the library. I didn't hear much of his progress until a while ago when he informed me he did a complete re-port of the 0860 source complete with the tests both as NUnit and as well as

One of the great new features of Silverlight 4 is drag-drop. This makes it possible to drag files from your OS onto the Silverlight application.   In this tutorial we’ll create a ListBox and make it possible to drop images from the desktop onto the application. The images will then appear in the ListBox.   First steps First of all we’ll create a “normal” Silverlight 4 App + Website using

Yesterday the beta release of Silverlight 4 was announced. Of course I couldn’t resist to get started with one of the items on my personal wish list (and on lots of other peoples wish list as well).   Using the webcam in Silverlight 4 turned out to be a quite easy process. I only needed about 8 lines to get it started. A few lines more and I have an application which starts and stops the webcam

I've seen quite some articles on repacking your XAP file to reduce the filesize. You can do this manually by using archiving utilities like 7-ZIP, WINRar or the Windows built in zip support.Delay did a great article on this which inspired me to do the following:I created a very small application called ReXapper.exe which can do exactly the same as Delay describes but there is no external

Don't tell Jeff, but here's a preview of another one of the projects in Foundation Silverlight 2 Animation.I made a little modification to this compared to the one that you'll create from the instructions in the book, assuming you're going to get it of course :).To make the dragon move more "natural" I used a DispatcherTimer with a random duration to make it change direction at a random

On the Silverlight forum I've seen a lot of questions regarding authentication and security.I figured I'd write something down from my perspective as an ASP.NET developer. This isn't the only way to do it and probably not the best, but it does what I need it to do and it might get you started in the right direction.IMPORTANT NOTE: This article is built with the assumption that all files requested

In some occasions you might want to show or hide stuff in your Silverlight application when the visitor stopped moving his/her mouse.For instance, most media players use this method to hide the play/pause/forward/mute controlbar.You can achieve this by doing following this:1. Create a DispatcherTimerprivate DispatcherTimer _nomousemoveTimer = new DispatcherTimer();2. Use the constructor of your

For an animation I did for a customer I wanted it to start the storyboard when the mouse enters and to play backwards, until the state it started in, when the mouse leaves the object. At this time, in Silverlight 2 beta 1, there is no method I found to play a storyboard backwards from a custom position in the timeline. There is an option to AutoReverse the storyboard but this only occurs when

One of the nice features in Silverlight 1.1 alpha was, in my opinion, the use of zipfiles and being able to use files from a zipped file by using the Downloader object. In Silverlight 2 the Dowloader is replaced with the WebClient. Which is not a bad thing, but it seems to be missing the ability to use zipfiles. Or I've missed it somehow... Anyway, I stil wanted the thumbnails on my site to be

They look great and in the demo app I've downloaded they seem to work well too.

In expectation of Silverlight 2.0 I decided to do some experimenting with some of the Live API's. I build a small app which shows my Live Messenger status. And can also show other peoples status if they gave permission. For now, all you see is a big Messenger icon I created in XAML.
