New year – new blog or how to migrate Community Server to any other engine, supports XML-RPC

Tamir Khason — Fri, 02 Jan 2009 02:33:04 GMT

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.

Programming for Windows 7

Well, Windows 7 is going to be released by the end of next year. This is great news, because it seemed, that Microsoft finally understand how to get the best of Windows Vista and make it to work not only on monster machines.

It even works on new brandy my wife's pinky machine. And if it works there and my wife is happy with it, this OS going to be very impressive.

But from the other hand, we, as developers should be ready today to developer Windows 7 ready application (by the way, Vista Battery Saver works for Windows 7 as well as for Windows Vista, in spite of the fact, that power management in Windows 7 was improved dramatically). So let's start!

First thing we need is to read big Windows 7 Developer Guide. This document will explain most of new features for developers to build applications right. What is includes?

Windows Driver Kit (WDK) 3.0

Basically, Windows 7 works with Vista drivers, however, hibernation, power management, networking, PREfast will work much better. You also will have new WMI access for reliability monitors and ACPI.

Management and deployment

By default Windows 7 uses PowerShell 2.0 and Windows Installer. For PowerShell it includes enhanced cmdlets to manage Active Directory, IIS, etc. For Windows Installer, you finally can build "chainers" by yourself (the same approach, used for latest deployment of Microsoft products such as Silverlight, Visual Studio 2008 SP1 etc.) Also, you can get advantage by using Windows Filtering Platform (Firewall) and User Account Control (UAC) from inside your application by using new APIs.

Performance

The most significant change in Windows 7 for end-user point of view is improved performance. Windows 7 kernel is much smaller, that kernel of Windows Vista. Also it uses specific patterns to decrease background activities on low power, based on system triggers. New user-mode and kernel-mode APIs are used by Windows Drivers Foundation much more efficiently. Also system services are much smarter. For example, DCIA starts only when you connect new hardware. After drivers were installed the service shuts down. The same approach used by domain join, GP changes, new IP fetching etc. Windows 7 knows to run and stop services, based on system events, which decreases average work load and enhances whole system performance.

Multi-touch gestures and Interia API and used interface in general

Yes, you can use this API for your applications. Finally we can have more, then just mouse. And it is not only about multiple mouse devices. We can use single finder panning, raw touch input data, internal multitouch ink recognition, which is also supports math. Also it uses build-in MathML export feature.

There are a lot of other enhancements, such as smart bars, windows' stacking, gadget desktop (it does not eat battery as external process anymore), system ribbon menu integration. etc

Graphics

Direct 11, new Direct2D, DirectWrite (we can turn text anti-aliasing for small fonts, hurrah!), improved WIC, DX/GDI interoperability on system level with automatic fallback for weak hardware (yes, you should not be worry about it anymore). Also new video and audio format support with human readable interfaces. Yes, no more DirectDraw hacks. We can use new high level interfaces such as MFPlay to manage playbacks, Source Reader for decoding, Sink Writer for transcoders and re-coding compressions.

Web and communication

WCF is inside, as well as distributed routing table for peer-to-peer operations. BranchCache - new technology to reduce WAN traffic and latency.

Also Windows 7 is compatible with OpenSearch (I told, that Microsoft does not know to build search engines). Sharepoint integration and environment sensors platform, that can be used either for desktop and web applications.

There are much more features, that makes Windows 7 to pretend to be very good operation system. If you want to learn more about all those Windows 7 new features, I highly advice you to download and read this document. It includes most of new features of new OS with explanations and screenshots to make your learn and understand what can your future application do with all those new features.

Have a nice day and be good people.

BTW, if you have PDC version of Windows 7 and want to unlock it for using of some cool features, introduced during keynotes, it worth to visit here and learn how to :)

Download Windows 7 Developer Guide and start programming.

New version of outstanding Exchange synchronization tool for Nokia phones is out. There are no big changes, except heart beat implementation of ActiveSync and fixes to contacts mapping bug is there. The main feature of this version is, that it can now run on any S60 phone (including 3.0, 3.1 and 3.2 devices), not only on E and N series. Full list of changes can be found here.

The bad news is, that Nokia MFE 2.7 still does not support inbox folders synchronization. This is the main feature missing in this great software. However, according the update rate, it should arrive soon.

Huge amount of people asked me about DataGrid control in WPF. There are some 3rd parties providing this control for free and not, However, I always adviced them to wait until Microsoft will release it with (or after) Arrowhead. So here comes the King. Some boys and girls from MS WPF dev team have OS initiative and released WPF toolkit. It’s absolutely free and includes all sources. Also it renewed with WPF DataGrid CTP and other tasty Futures inside with full source aside.

Microsoft goes open source? It does!

Arabic and Hebrew languages bidirectional support for Silverlight 2.0 beta 2

The new URL of this post is http://khason.net/blog/arabic-and-hebrew-languages-bidirectional-support-for-silverlight-20-beta-2/]

Those days, I’m, together with guys from Microsoft Egypt and Santeon, finishing development of bidirectional input and output support for Silverlight. I want you to take part in alpha testing of this solution. Please see the test form here and try it.

&lt;noframes&gt;Visit &lt;a href="http://blogs.microsoft.co.il/blogs/tamir/archive/2008/07/17/arabic-and-hebrew-languages-bidirectional-support-for-silverlight-2-0-beta-2.aspx"&gt;original article&lt;/a&gt; to test&lt;/noframes&gt;

Also, you can download latest development build or compiled binary version with debug symbols and try it yourself. Please, if you’re in any issue, report it, by using issue tracker in CodePlex.

In order to use it, all you have to do is to use custom namespace within your project and then, you’ll be able to get almost all controls, you know, but with Arabic and Hebrew RTL and LTR support. You have to set one property: FlowDirection to change the rendering method (exactly as in WPF). Here an example of usage.

<UserControl x:Class="BidiTest2.Page"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:l="clr-namespace:System.Windows.BidiControls;assembly=BidiControls">
…
<l:TextBlock FlowDirection="LeftToRight" Text="שלום עולם"/>

<l:TextBox FlowDirection="RightToLeft" Text="{Binding Text, Mode=TwoWay}"/>

That’s all. Thank you for your cooperation.

For last days I’m very busy with Bidi support for Silverlight development. Working a lot of hours in order to finish it until TechEd. So, I’m very tired and need relaxation. What can be better, then Tetris? But, there are millions of Tetrises. What to choose? What’s the question? The original one.

This genius game was developed by Vadim Gerasimov, Alexey Pajitnov and Dmitry Pavlovsky about 20 years ago and it still working on Windows PC (even in Vista). This how to build software. As far as I know, today Vadim works in Google, Alexey in WildSnake and Vadim is commercial director somewhere in Russia.

So, download and play Tetris now. Unfourchantely, 16 bit Antrix requires full screen emulation, that is not supported on Vista.

Silverlight controls library has been upgraded to Beta 2

Tamir Khason — Sun, 15 Jun 2008 21:35:51 GMT

[This blog was migrated. You will not be able to comment here.
The new URL of this post is http://khason.net/blog/silverlight-controls-library-has-been-upgraded-to-beta-2/]

Finally this weekend I got a time to upgrade one of my OpenUp submissions, Silverlight controls library to work with Silverlight 2.0 beta 2. It was very interesting to track changes between developer’s (beta 1) and production (beta 2) go-live licenses. Let’s try to understand what has need changed.

Syntax of DependencyProperty registration. Now instead of DependencyProperty.Register(name, propertyType,ownerType,propertyChangedCallback) you should use DependencyProperty.Register(name, propertyType,ownerType,typeMetadata), which, actually receives only one parameter in constructor – propertyChangedCallback. This make Silverlight to be closer to WPF syntax and open it for future enhancements. You can download updated Visual Studio 2008 snippet for creation of Silverlight Dependency Properties.
OnApplyTemplate method of UserControl become public instead of protected
Thumb DragDelta event argument is not DragEventArg anymore. Now it’s DragDeltaEventArgs. So there is no HorizontalOffset and VerticalOffset attributes. They replaced by HorizontalChange and VerticalChange
DefaultStyleKey is not null anymore
Most of controls migrated from System.Windows.Controls into System.Windows namespace
Some changed to ToolTip service
Now Silverlight checks whether TargetType property of Style is really compatible with the control, you’re applying style to (this not happened in beta 1). Also DependencyObject.SetValue() method checks it’s type.
There is no InitializeFromXaml anymore. Now Silverlight works more “WPF style” with application services – Application.LoadComponent()
You cannot use x:Name and Name property together (someone did it?)

There are a ton of other changed, that was not related to Silverlight Control Library. For example, changed within Storyboard class, networking, cross-domain policy, other controls (e.g. DataGrid), Templates of some controls (e.g. Button, TextBox, etc) and API.

Also I want to invite you to take part into development of Silverlight controls library not because of complimentary ticket to PDC ‘08 or Mobile Memory Mouse 8000, but because Open Source is not “one-men-show”. To get access to SVN, submit your work and begin development of next generation of Silverlight controls, contact me via CodePlex and I’ll add you to the project as new contributor.
