Please update your bookmarks, because the new url of this blog is http://khason.net/ (you have not update RSS feeds, it will be done automatically). Why I did it? Why I decided to go to “stand-alone”… Well. there are some reasons. Generally, I do not want to explain all those here, but trust me, there are some. The main reason is, that there is no responsible person in charge for this blog platform in Microsoft Israel. This why, if your blog is popular and you have a respect to your blog visitors, you cannot host it here… Take a look into new comments notifications in my inbox. Would you answer your readers with such “small amount” of SPAM and capcha, that cannot be fixed already for three years in this platform? This how my inbox looks like for last three years. So now, you should not ask me, why I not answered your email or comments. Aren’t you? :)

Currently, all comments in this blog are disabled, so if you want to comment, please use new url of posts (this will appear shortly in the beginning of each post). Also, this post will not be syndicated in RSS.

So, this post is the last. I loved this platform, and loved people started it. But, unfortunately, it seemed, that bloggers community is not important enough for new platform managers.

Also, If you want to learn how to use C# and XML-RCP to migrate from CS2007, used in this platform, visit my new home :)

Have a great year and, as always, be good people. This post marked with all possible tags automatically. Sorry.

Save the date. TechEd Developers South Africa is around the corner (August 3rd through 6th). This year it will take place in Durban, the third most populous city in South Africa.

This TechEd, there are four sessions assigned to me:

Creating Rich Applications with Windows Presentation Foundation (300)

Completely new session about how to enrich user experience, by decreasing development efforts with WPF. In order to do this, we’ll try to take some application and completely recreate it, by using XAML only without any single code line.

Target audience: Developers and decide makers, who what to understand what can be done with WPF and how easy you can do it.

Understanding Reflection (400)

This is also new session for lazy developers. It’s not only about what reflection is or what’s new about reflection in latest frameworks (including .NET 3.5 and Silverlight), but also how to use it to make developer’s life easier. We’ll enter a bit into IL to understand what’s going on under the hoods, but most of session is about appliance of this technology for everyday developers’ tasks and challenges.

Target audience: Developers, have an experience with .NET programming

WPF Performance (400)

Session very similar to one, I had in Dev Academy 2. However this time it will focus on performance enhancements in .NET framework 3.5 SP1. I’ll speak about virtualization, parallel processing, DX surface direct access and more…

Target audience: Developers, have an experience with WPF development.

Game Development Using Microsoft’s Latest Technologies (300)

Fun session, I had in TechEd Israel with very complicated setup. Here the sneak preview of how it looks like. It listed as a 300 level, because the fact, that except this session’s fun, you can learn a lot of new there.

Target audience: Everyone, who love technology and want to have fun hour in the morning before advanced sessions will begin.

If you’re reading my blog, and you’re going TechEd Africa. Come and say me hello, ‘cos it would be really nice to see the faces of the people I’m writing to in this blog :)

More information about other sessions in this TechEd can be found in Ahmed Salijee blog, who is developer evangelist in Microsoft Africa and arranges this event.

See you there.

Do you want to build XNA games for Zune? Do you want to do in from Visual Studio 2008, rather, then from Visual Studio 2005? Download new technology preview of XNA Game Studio. Currently you cannot build games for XBox with XNA GS 3.0 – only for Zune and PC? What does it mean? Actually nothing, but worth a try. Also, you can see in my blog what you can do with it.

Where to get it? From XNA Creators Club online. For more information, visit XNA team blog.

I do not know why, but for some reason in development section of TechEd website there are only two recording and no presentations. I do not want to wait for them to upload (we sent all presentations a while ago), so here it comes. My TechEd presentation DEV335 - Game Development Using Microsoft’s Latest Technologies. I have no recordings by now (so pity), so you’ll have to wait for Microsoft to encode and upload it. Upon it will be done, I’ll publish it here.
There is no real reason to upload samples – they will not work without all environment we had there.

Download full slides from my TechEd presentation (PPT 7,165 KB) >>

If you have any questions, feel free to contact me by using contact form or LinkedIn profile. You also can send me a message by twitter

After a lot of work I’m ready for TechEd. It worth me a lot of blood, sweat and tears until it started to work as I expected. What our session about? In one sentence – Game Development. In number of sentences – we’ll build online car racing multiplayer game, that will run on XBOX, Windows, Linux, Mac and mobile phone. All this will be tied up with Windows Live services. During the session, XBOX will play with WPF and Novel Suse Linux will run ASP.NET and play with IIS7. Don’t believe me? Come and see. Here small video, that demonstrates some of this session results. There are much more to see…

See you there 8th of april, 10:45 in Knaan hall of Hilton hotel in Eilat.

Running WPF on gas pump (or other Windows CE devices)?

Tamir Khason — Thu, 13 Mar 2008 20:06:07 GMT

[This blog was migrated. You will not be able to comment here.
The new URL of this post is http://khason.net/blog/running-wpf-on-gas-pump-or-other-windows-ce-devices/]

What do you think, is it possible to run WPF on Windows CE enabled devices (e.g. gas pumps, GPS systems, robots, game or automatic teller machines or, even, scientific calculators)? Let's see following code:

StackPanel panel = new StackPanel(Orientation.Horizontal);
            Ellipse ellipse = new Ellipse(10, 10);
            ellipse.Fill = new SolidColorBrush(Colors.Red);
            ellipse.Stroke = new Pen(Color.Black);
            Rectangle rect = new Rectangle();
            rect.Width = 40;
            rect.Height = 40;
            Line l = new Line(20, 20);
            Polygon polygon = new Polygon(new int[] { 0, 0, 20, 0, 20, 20, 0, 20 });
            panel.Children.Add(ellipse);
            panel.Children.Add(rect);
            panel.Children.Add(l);
            panel.Children.Add(polygon);

            panel.AddHandler(Buttons.ButtonUpEvent, (ButtonEventHandler)delegate
            {
                panel.Orientation = panel.Orientation == Orientation.Horizontal ? Orientation.Vertical : Orientation.Horizontal;
            }, false);

Or even this code

void OnButtonHeld(object o)
{
    Button b = (Button)o;
    Dispatcher.Invoke(TimeSpan.FromTicks(10), (ButtonHeldDelegate)delegate(Button btn)
    {
        while (Buttons.IsButtonDown(btn))
        {
            switch (btn)
            {
                case Button.Left: p.X--; break;
                case Button.Up: p.Y--; break;
                case Button.Right: p.X++; break;
                case Button.Down: p.Y++; break;
                case Button.Select: p.X = mainWindow.Width / 2; p.Y = mainWindow.Height / 2; break;
            }
        }

        moveMouse();
    }, b);
}

void moveMouse()
{
    host.DrawRectangle(Colors.Black,2,p.X,p.Y, 100, 100,0,0,Colors.Red,0,0,Colors.Blue,100,100,255);
    host.Flush();
}

This code will run on any Windows CE device. And it is not WPF :) It's .NET Micro Framework. Actually, when we're looking for it's syntax, it looks like WPF/Silverlight and .NET Micro Framework have the same architect. However, it cannot use hardware acceleration and has very limited number of objects. All this because of it's purpose "platform to devices that do not need the fuller functionality available in the .NET Framework and the .NET Compact Framework". I would add Windows Presentation Foundation as well.

The application model of .NET Micro Framework is very similar to WPF. It has native CLR/PAL and HAL and managed libraries.

Sufficient number of components in CLR - types, threads and timers, reflection, serialization, GC, networking, other connectivities etc., enables you to create, even games, that will run on even Heart Device.

Other words, cool technology and possible cool appliance for your programming skills.

How to start? First of all, download .NET Micro Framework v2.5 (VS2005, you can also add Microsoft.SPOT assemblies into your regular VS2008 project) and start programming. It's really simple (I build snake game for less, then hour)

See your applications, running on embedded devices. BTW, I'll probably present something, developed with this framework in my TechEd session aside with WPF, Silverlight and XNA... Keep tuned and have a nice day

Today is download day at MSDN. There are some very interesting things published.

New release of Windows SDK (new classes for WPF 3.5, bugs fixes, and enhanced support for Windows Server 2008, including speech, error reporting and UAC). Download it here. For more information, visit SDK blog
Windows XP SP3 RC2 (it's not final release), but if you want to try it (not in production environment) download it here. As well as if you are ready to harm your system. Give a try to Windows Internet Explorer 8 Beta 1 for XP (or for Vista/Home Server 2008, or Windows Server 2003 SP2).
There are some fixes for Microsoft XNA Game Studio 2.0 (make sure, that you know what is it. If not, come to see my TechEd session). Also, you can download Games for Windows - LIVE redistributable .
If you are lucky Zune owner, you can download PC software 2.3 for it
If you Virtual Earth fun, add realistic 3D capabilities to use online Live Search Maps.
If you still have no Silverlight Tools for VS2008, be sure to download it (this is not chained installer, tools only)

Enough for this morning. Warm up your download machines and start downloading.

This TechEd, me and Alex will explain how to make XNA, WPF and {censored} work together to develop entertainment stuff easier. In spite of the fact, that we'll explain a little about XNA core, it makes cense (if you want to know) to learn it yourself.

Trust me, XNA is brilliant framework, that makes you able to build games easier. You have not know DirectX or C++ in order to build your own WoW, Resident Evil, GTA or Halo. All you have to do is to visit XNA.com, download XNA Game Studio 2 and start programming your own game, that will run on your PC and XBOX.

Already done it and still do not know how to start? Let Dan to teach you. Visit his great video series about XNA development. Still frustrated and want to know more? Come and s ee me at TechEd'08 Eilat.
