.Net Framework 4.0: Using memory mapped files

Sun, 21 Jun 2009 10:05:49 GMT

.Net Framework 4.0 introduces memory mapped files. Memory mapped files are useful when you need to do in-memory data manipulation and your data structures are large. For large in-memory data the performance of memory mapped file is the best. It is much faster than MemoryStream. And like files on hard disc, memory mapped files can be shared between different programs.

As with all of the things in Prism, Regions are a part of the buffet. You can use them or not at your discretion.

A new custom behavior for WPF that allows for a glass like effect. Essentially you can place this behavior on any Visual, point to to a target visual and give it an effect and it will create an effect that looks like a piece of glass was placed over the screen.

Vista DWM Hacking - Capture and Stream D3D/WPF Windows Real-Time

Wed, 12 Nov 2008 06:16:09 GMT

This prototype project uses undocumented Vista DWM calls to get reference to a Direct3D surface the Vista DWM uses to paint windows. The D3D surface is then able to be rendered in a WPF application like a "VisualBrush". Because this is done in the GPU, it is very efficient. The sample application will also let you stream a high quality, high fps capture of your video to Silverlight or Windows Media Player.

Touchless - A webcam multi-touch SDK

Mon, 13 Oct 2008 04:01:02 GMT

That brings us to today, releasing Touchless to the world outside Microsoft, as a *FREE* *OPEN-SOURCE* SDK with a low barrier to entry for developers and users. Touchless makes developing multi-touch capable software easy, and the results can be enjoyed by anyone with a webcam (and some M&Ms :))! Touchless has come a long way, but its journey has just begun. I can imagine a variety of great directions to explore using Touchless. Perhaps support for the forthcoming Windows multi-touch API, video chat white-boarding, implementing mouse/game/hotkey/media control, and designing decked out Minority Report style file/media browsers.

YouCube (3D WPF web browser)

Thu, 04 Sep 2008 15:46:59 GMT

As you know, .NET 3.5 SP1 includes a WebBrowser control. The current implementation is just a wrapper around the MSHTML ActiveX control, which unfortunately prevents you from doing crazy things to it through WPF. The ActiveX control itself can be queried for the IViewObject interface and have its Draw method called. The WPF WebBrowser doesn't expose this directly, but fortunately the Windows Forms WebBrowser does (alternatively you could host MSHTML directly)...
