Silverlight 2 is great technology, but some of very handy User Controls are still missing from it.
Alex Golesh has released to openup a project called Silverlight Tree View that provides Tree View user control for Silverlight 2.

Thanks Alex !

Silverlight String-To-PathGeometry Converter

ashevat — Sun, 29 Jun 2008 16:47:11 GMT

Alex Golesh has release String-To-PathGeometry Converter to OpenUp.

About the project: "Silverlight 2 is great technology. But for some developers who used to work with WPF there are some missed helper classes, which are very handy.
One of them is “PathFigureCollectionConverter” object, which accepts string with figure path definition and convert it to Geometry object. This project provides similar functionality for Silverlight 2: it accepts string with path definition, and return PathGeometry object which could be used in Silverlight 2 applications to set “Data” property for Path object. Also, it can convert PathGeometry object back to string with path definition."

Thanks Alex!

Shidonni, an Israeli startup has released a preview of their new, Silverlight based, game for kids. The basic idea is that you draw a creature and then feed it and take care of it and its offspring. They really show the potential of Silverlight and what can be done with this technology on the web.

The guys there have done a great job and my kid played with it for a very long time :)

WebCam control for WPF, Silverlight controls library and Duplicate images finder

ashevat — Mon, 19 May 2008 01:07:00 GMT

Tamir Khason has contributed a great set of projects to OpenUp, Microsoft open source competition.

WebCam control for WPF:

Reusable WPF control to display high frame rate video such as WebCam or framegrabber DirectShow output. This control uses InteropBitmap introduced in .NET framework 3.5 and managed DirectShow P/Invoke. This control does not uses DirectShow.net library, so it's completely independent.

Silverlight controls library:

This is the library of WPF (and not only WPF) controls, Tamir is missing in Silverlight 2.0.

Duplicate images finder:

This application can search through your images collection and find duplicates not only by file name or size, but also by visual similarity. Its done by implementation of some public domain algorithm to do its work.

Cheers Tamir :)

Visual WebGui - An Enterprise AJAX application in 20 minutes.

ashevat — Wed, 13 Feb 2008 22:24:16 GMT

Gizmox is an Israeli startup that developed an application UI framework that bridges good-old practices of building enterprise applications (using WinForms) with web 2.0 style application delivery (AJAX style). The idea behind their solution is that the WinForm application style can be sub classed to have a class that separates the UI implementation (and optimizes the communication between the UI and the application logic) from the UI logic. The result is that one can develop a Windows Forms style application and the WebGui class underneath emits an ASP.NET application that maintains states and connects a JavaScript based UI to the application UI logic that runs on the server. The result is a modern Web 2.0 style application that was developed with the Windows Forms UI paradigm. Note that the application is an ASP.NET application and can be extended in a standard way. The technology is licensed under an LGPL license and already in use by large enterprise customers (SAP is using it for their labs application).

Microsoft is holding a Webcast about this technology and I highly recommend registering and attending it.
