The XPS Essentials Pack has been updated to support Windows XP Service Pack 3

kenlin — Mon, 05 Jan 2009 02:58:00 GMT

The XPS Essentials Pack installer (available via www.microsoft.com/xps) does not currently support Service Pack 3 (SP3) of Windows XP.

To enable XPS support on Windows XP SP3, you can install the XPS Essentials Pack prior to upgrading to SP3.

In the end of Oct 2008, XPS team has released a new updated. This update fixes a problem with the installer where it failed to recognize a newer version of Windows Imaging Component (WIC) that is included in Windows XP SP3. Also included is an update to the latest version of the XPS Print Path, as well as including a number of improvements to the print path, this update corrects an issue with the components previous included in the essentials pack that prevented component servicing.

To download the installer see http://www.microsoft.com/whdc/xps/viewxps.mspx.

P.S. You cannot get this download from http://www.mircosoft.com/download.

Good tool to find any accounts with Application SPNs.

kenlin — Fri, 07 Nov 2008 02:25:00 GMT

I recently discovered a phenomenal tool for listing the SPNs. You can find the VBScript on Microsoft's website below:

http://www.microsoft.com/technet/scriptcenter/solutions/spnquery.mspx

Using this tool, you can locate any accounts with Application SPNs as follows (you can name the VBScript whatever you like):

C:\cscript queryspn.vbs App123*

Running the script above will list out all the accounts (with all their SPNs ) with SPNs that begin with "App123"

Windows Azure Services

kenlin — Fri, 31 Oct 2008 03:26:00 GMT

Windows® Azure is a cloud services operating system that serves as the development, service hosting and service management environment for the Azure Services Platform. Windows Azure provides developers with on-demand compute and storage to host, scale, and manage Web applications on the Internet through Microsoft® data centers.

To build these applications and services, developers can use their existing Microsoft® Visual Studio® 2008 expertise. In addition, Windows Azure supports popular standards and protocols including SOAP, REST, and XML. Windows Azure is an open platform that will support both Microsoft and non-Microsoft languages and environments. What is the Azure Services Platform?

Embrace the new .NET Logo!

kenlin — Sun, 26 Oct 2008 15:39:00 GMT

There is a new logo for .NET now, so it is change

from into

The following are the blog from the .NET Team about the new logo.

Why did we do it?

We needed a logo that was in sync with the key values that we want .NET to stand for: consistency, robustness and great user experiences. We also wanted a logo that conformed to the design principles that are driving Microsoft’s brand identity evolution and is reflected in newer brands such as Silverlight, Surface and more. Finally, we needed a logo that is more strongly aligned with the portfolio of brands that .NET is most strongly aligned with: Silverlight, Visual Studio and the AppPlat server products.

The result is a design we refer to as the “wave.” The design is strong, simple and distinctive. The suggestion of the letter ‘N’ in the design will become instantly recognizable over time as shorthand for the .NET brand name.

It's one of many things we're actively doing to renew our commitment to the future around the overall Rich Platforms we have today.

Hope all have fun at PDC2008 and you'll see glimpses of what I mean there ;)

Onwards and embrace the new .NET logo!

Zumobi - Stop Surfing, Start Zooming!

kenlin — Fri, 28 Dec 2007 03:47:00 GMT

Zumobi, the mobile startup spun off from Microsoft Research, has launched its first beta. The Zumobi lets you access, enjoy, and share web-based content on your mobile phone in an innovative, new way. The Zumobi software presents a unique way to access content, with a grid of sixteen tiles that you can zoom in and out of, and the tiles acting as widgets that display web-based content.
Currently, mobile browsing goes something like this…

Either you navigate through a list of web sites pre-loaded on your phone, navigate through static bookmarks, or maybe even attempt to type in a long URL with your thumbs. Ugh.
Now that you’ve chosen your content, wait while it loads. And wait. And wait.
Ok, site loaded. Read a few lines and scroll down. Scroll down. Scroll down, deeper into the abyss searching for what you wanted buried somewhere in all that content. Tedious. Often frustrating.
Rinse, repeat.

Ultimately, it’s an underwhelming experience.

Enter Zumobi. Beta Launch Video On YouTube

They are also recruiting Beta Users, To participate in the Zumobi Beta you’ll need the following:
Zumobi Tiles create a solution through which advertising and marketing communications are highly contextual and personalized.

A U.S.A. mobile phone number
A data plan with your mobile phone service provider (we strongly recommend this be an unlimited data plan)
A mobile phone running Windows Mobile 5 or 6

While Zumobi is compatible with most phones running Windows Mobile 5 or 6, we have certified and recommend the following devices for optimal performance:

Motorola Q
Samsung Blackjack 1.0
HTC Dash
HTC Touch

Of course, you are also welcome to download and test Zumobi on other Windows Mobile 5 or 6 phones, but we have not fully certified these phones yet and cannot guarantee an optimal experience. Additional certified phones will be added frequently, so please check our website for the most current list of devices.

[Microsoft Live Labs] Volta: Web Development Using Only the Materials in the Room

kenlin — Fri, 07 Dec 2007 03:07:00 GMT

Today, Microsoft Live Labs is announcing the Volta technology preview, a developer toolset for building multi-tier web applications using existing and familiar tools, techniques and patterns. Volta’s declarative tier-splitting enables developers to postpone architectural decisions about distribution until the last possible responsible moment. Also, thanks to a shared programming model across multiple-tiers, Volta enables new end-to-end profiling and testing for higher levels of application performance, robustness, and reliability. Using the declarative tier-splitting, developers can refine architectural decisions based on this profiling data. This saves time and costs associated with manual refactoring. In effect, Volta extends the .NET platform to further enable the development of software+services applications, using existing and familiar tools and techniques.

You architect and build your application as a .NET client application, assigning the portions of the application that run on the server tier and client tier late in the development process. You can target either web browsers or the CLR as clients and Volta handles the complexities of tier-splitting. The compiler creates cross-browser JavaScript for the client tier, web services for the server tier, and all communication, serialization, synchronization, security, and other boilerplate code to tie the tiers together. In effect, Volta offers a best-effort experience in multiple environments without requiring tailoring of the application.

Microsoft Commits to November Release Date for Visual Studio 2008 and the .NET Framework 3.5

kenlin — Tue, 06 Nov 2007 06:49:00 GMT

BARCELONA, Spain — Nov. 5, 2007 — Today, during the keynote address at Microsoft TechEd Developers 2007, S. “Soma” Somasegar, corporate vice president of the Developer Division at Microsoft Corp., announced that Microsoft will release Visual Studio 2008 and the .NET Framework 3.5 by the end of November 2007. Visual Studio 2008 and the .NET Framework 3.5 enable developers at all levels to rapidly create connected applications that offer compelling user experiences for Windows Vista, Windows Server 2008, the 2007 Microsoft Office system, mobile devices and the Web. Soma also unveiled plans to open new opportunities for Visual Studio partners, as well as to deliver new tools and resources for developers, including a first Community Technology Preview (CTP) of the Microsoft Sync Framework and new capabilities for Popfly Explorer.

“The highly social and visual nature of the Web has fundamentally changed what users expect from all applications they interact with, regardless of whether it’s on a customer-facing Web site or Windows rich client application, or a desktop business application built using Microsoft Office,” said Somasegar. “Traditionally, organizations have been hard pressed to deliver the richer, more connected applications and services they need to boost productivity, drive revenue and stay ahead of the competition. With Visual Studio 2008 and the .NET Framework 3.5, it is easy for developers to use the skills they already have to build compelling applications that take advantage of the latest platforms.”

FWBS Ltd., Xerox Corp., Dell Inc. and K2 are just a few of the early adopter customers that are already experiencing the benefits of these releases. FWBS used Visual Studio, the .NET Framework and the Microsoft Office system to build an Office Business Application (OBA) for the law field. The application enables users to work within Microsoft Office — the tools they use every day — while also dramatically improving productivity and helping users respond quickly to changing business needs.

Xerox has also had early success developing applications with the new tools. “We’ve already seen significant advantages from using Visual Studio Team System 2008 and .NET Framework 3.5. With the first application we built, we easily saved 50 percent of the time and money it would have taken to create the same application with other tools,” said Eugene Shustef, feature design lead, Global Technology, Xerox. “That’s more than a savings to IT — it delivers a huge time-to-market advantage because it put the tool into the hands of our analysts six months sooner than they would have had it otherwise.”

Creating New Opportunities for Partners

Microsoft also announced plans to make additional investments in the Visual Studio partner ecosystem. In response to partner feedback and in order to provide better support for interoperability with other developer tools and cross-platform scenarios, Microsoft is today announcing plans to change licensing terms, no longer limiting partners to building solutions on top of Visual Studio for Windows and other Microsoft platforms only. This licensing change will be effective for the release of Visual Studio 2008 and the Visual Studio 2008 SDK.

“Integrating dynaTrace’s cross-platform application performance management and diagnostics product with Visual Studio has opened up additional commercial opportunities for our business and delivered a compelling solution for our customers. .NET and Visual Studio is a strategic platform for our business, and Microsoft’s additional investments in the partner ecosystem make it even more compelling,” said Klaus Fellner, senior director of product marketing at dynaTrace. “We’re looking forward to taking advantage of the new technology available with the launch of Visual Studio 2008 and the partner benefits available through the Visual Studio Industry Partner (VSIP) program.”

In addition, Microsoft announced plans to create a shared source licensing program for Premier-level partners in the VSIP program. The program will provide these partners with the ability to view Visual Studio IDE source code for debugging purposes, and simplify the process of integrating their products with Visual Studio 2008.

Tools for Today and Tomorrow

Microsoft also announced a number of additional resources for developers of all skill sets, enabling them to make the most out of their Microsoft tools investments to build great applications on the latest platforms:

•

The first CTP of the Microsoft Sync Framework demonstrates Microsoft’s ongoing investments in synchronization and builds on the synchronization functionality available in Visual Studio 2008. With Visual Studio 2008, developers can rapidly take advantage of offline synchronization capabilities to sync-enable applications and services easily with rich designer support. The Microsoft Sync Framework extends the support featured in Visual Studio 2008 to also include offline and peer-to-peer collaboration using any protocol for any data type, and any data store. This is part of Microsoft’s long-term commitment to providing synchronization for partners and independent software vendors that can embed the Sync Framework into their applications easily to create rich sync-enabled ecosystems that allow any type of data to follow their customers wherever they go.

•

A new release of Popfly Explorer will add new Web tools that provide Web developers and Popfly users an easy way to add Silverlight gadgets built in Popfly to their Web pages, as well as publish HTML Web pages directly to Popfly.

These latest releases are part of the broader Microsoft Application Platform, a portfolio of technology capabilities and core products that help organizations develop, deploy and manage applications and IT infrastructure. They also mark another major milestone leading up to the global launch of Windows Server 2008, Visual Studio 2008 and SQL Server 2008 on Feb. 27, 2008, in Los Angeles.

Product Information and Availability

Visual Studio 2008 and the .NET Framework 3.5 will be available by the end of November 2007. The .NET Framework 3.5 will also be available to end users via a free, optional download from Microsoft Update. A CTP of Microsoft Sync Framework is available today at http://msdn.microsoft.com/sync. Popfly Explorer is a hosted development environment available today at http://www.popfly.com. More information about all of these releases is available at http://www.msdn.microsoft.com/vstudio.

Enable ASP.NET AJAX v1.0 to your existing ASP.NET 2.0 Web Site or Web Application.

kenlin — Mon, 05 Nov 2007 10:59:00 GMT

Few days ago, I shared about how to upgrade your ASP.NET 1.1 to ASP.NET 2.0, this time I am going to discuss about enabling ASP.NET AJAX v1.0 to your existing Web Site or Web Application.

1) You have to downlaod and install the ASP.NET 2.0 AJAX Extensions 1.0. Here
2) You may download and extract the ASP.NET AJAX Control Toolkit. Here

After install it, you will found out that you may create AJAX Enabled Web Application when creating new projects(Web Site or Web Application). You may also found out that there is a new tab called "AJAX Extensions" in Toolbox. If you have extracted the ASP.NET AJAX Control Toolkit, you may do the following,

1) Create new tab called "AJAX Control Toolkit";
2) Right click under the created tab and click on "Choose Items...";
3) Click "Browse..." and browse to the folder which you extract the ASP.NET AJAX Control Toolkit, and then browse to "~\SampleWebSite\Bin\" and select AjaxControlToolokit.dll
4) Now you will see a lot of controls which you are ready to use. You may browse and view the "Toolkit Live" to get the sample and idea on the controls.

You are now ready to build your AJAX web site or web application. However, if you have any existing ASP.NET 2.0 Web Site or Web Application, you do the normal action to write AJAX, you will found out that the AJAX is not working in your existing Web Site or Web Application. You have to do the following in order to let your existing ASP.NET 2.0 Web Site or Web Application to be "AJAX Enabled",

1) Open web.config from your existing web site or web application
2) Add the following XML under <configuration> tab.

<configSections>

Releasing the Source Code for the .NET Framework Libraries

kenlin — Thu, 01 Nov 2007 03:11:00 GMT

Read from ScottGu's blog and knowing this news,

One of the things my team has been working to enable has been the ability for .NET developers to download and browse the source code of the .NET Framework libraries, and to easily enable debugging support in them.

Today I'm excited to announce that we'll be providing this with the .NET 3.5 and VS 2008 release later this year.

We'll begin by offering the source code (with source file comments included) for the .NET Base Class Libraries (System, System.IO, System.Collections, System.Configuration, System.Threading, System.Net, System.Security, System.Runtime, System.Text, etc), ASP.NET (System.Web), Windows Forms (System.Windows.Forms), ADO.NET (System.Data), XML (System.Xml), and WPF (System.Windows). We'll then be adding more libraries in the months ahead (including WCF, Workflow, and LINQ). The source code will be released under the Microsoft Reference License (MS-RL).

You'll be able to download the .NET Framework source libraries via a standalone install (allowing you to use any text editor to browse it locally). We will also provide integrated debugging support of it within VS 2008.

Full story is here

Upgrading ASP.NET 1.x to ASP.NET 2.0

kenlin — Tue, 30 Oct 2007 07:24:00 GMT

Last time, I speak in UserGroup gathering in 2007 Sept right after MSDN Seminar, the topic was "Experience Sharing: Upgrading ASP.NET 1.x --> 2.0 --> AJAX". Well, I also promised that i will blog about it. Actually, it is nothing new and it is nothing special. I just shared my experience on how I upgrade ASP.NET 1.1 to 2.0 and how to enable AJAX.

First, I am not sure if you know that, in .NET framework 2.0, there is 2 types of Web Projects, ASP.NET 2.0 Web Site and ASP.NET 2.0 Web Application. You may refer to the following link for more information if you would like to read more.

Introduction to Web Application Projects
http://msdn2.microsoft.com/en-us/library/Aa730880(VS.80).aspx

If you are going to upgrading your existing ASP.NET 1.x project, you should choose to be using ASP.NET 2.0 Web Application project. This is the message from one of ScottGu's blog, Tutorial on VB and C# are also mentioned.

"Because the VS 2005 Web Application Project model has the same conceptual semantics as the VS 2003 Web Project Model, it also makes migrating VS 2003 web projects very, very easy – with zero/minimal code changes required. To learn how to automatically upgrade a VS 2003 web project using this option, please review these VB and C# tutorials that walkthrough the VS 2003 to VS 2005 upgrade process step-by-step."

However, if you want to move your existing ASP.NET 2.0 Web Site to ASP.NET 2.0 Web Application, you may read the following message from ScottGu's blog,

"If you want to migrate an existing VS 2005 Web Site Project to be a VS 2005 Web Application Project, please also review these other VB and C# migration tutorials that walkthrough the Web Site to Web Application conversion process step-by-step. This article here also describes some of the differences between the VS 2005 Web Site Project Model and VS 2005 Web Application Project Model. "

Q: How can I create ASP.NET 2.0 Web Application Project?
A: Your machine must installed VS2005 with SP1 in order to create ASP.NET 2.0 Web Application Project

Q: I don't want to install VS2005 SP1 at the moment, any other way?
A: you need the deprecated “Microsoft Visual Studio Web Application Projects” installer you can find it here.

Q: Anything I need to download if I am going to start developing in ASP.NET 2.0 Web Application Project?
A: Available as a separate download is a custom build tool for generating a strongly-typed Profile class for the ASP.NET 2.0 Profile system. This allows you to right-click on a web.config file containing profile declarations and auto-generate the Profile type into your code-behind project assembly. You can learn more about this and download it here.

Q: I would like to read more and the full story on ScottGu blog.
A: Sure, you may go to ScottGu's blog - VS 2005 Web Application Project V1.0 Released

Q: Any other resource from Microsoft Official link?
A: Sure, here you are, MSDN: Upgrade from ASP.NET 1.x

Q: You mentioned ASP.NET 2.0 to AJAX....
A: Yes, I am going to blog about it later on. Please come back some time for more detail.

Knowledge of language features, "Operator Overloading "

kenlin — Mon, 14 May 2007 20:29:00 GMT

Well, I am one of the VB insiders, we are talking about a video. This video is a chatting video between 5 guys from difference team(VB, C#, C++, Channel 9 interviewer). They are going to answer you few question about the language future from their view when developing CLR/LINQ/VB/C#/C++. But the point we VB Insider discussing is, one of them, Brian Beckman has spoken that he likes C# because of the "Operator Overloading" support. That means he does not know that VB.NET(Or shorten called VB9 now) also has operator overloading support.

Another interesting issue I found afterward, I open up .NET Documentation, type the "operator overloading" keyword in Index Tab, I found a C# article("Help me, I am overloaded") on Operator Overloading and explain to you how to do so, why to do so(ms-help://MS.VSCC.v80/MS.MSDN.v80/MS.VSADD.v10.en/dncscol/html/csharp06212001.htm). But when I click in VB, it only shows you the "SAMPLE"(ms-help://MS.VSCC.v80/MS.MSDN.v80/MS.VisualStudio.v80.en/dv_vbcode/html/30202e10-8bdc-47dc-8fd1-f0ff9ffa0641.htm). Oh...god...no article in VB? How the VB beginner learn and understand it then? No wonder why he said the above comment.

Anders Hejlsberg, Herb Sutter, Erik Meijer, Brian Beckman: Software Composability and the Future of Languages

Posted by Charles // Mon, Jan 22, 2007 1:09 PM

How will imperative programming languages evolve to suit the needs of developers in the age of Concurrency and Composability? What role can programming languages play in enabling true composability? What are the implications of LINQ on the furture of managed (CLS-based) and unmanaged(C++) languages? How will our imperative languages (static) become more functional (dynamic) in nature while preserving their static "experience" for developers?

Answers to these questions and much more are to be found in this interview with some of Microsoft's leading language designers and programming thought leaders: Anders Hejlsberg, Technical Fellow and Chief Architect of C#, Herb Sutter, Architect in the C++ language design group, Erik Meijer, Architect in both VB.Net and C# language design and programming language guru, and Brian Beckman, physicist and programming language architect working on VB.Net.

This is a great conversation with some of the industry's most influential programming language designers. Tune in. You may be surprised by what you learn...

What do the announcements at Mix mean for the Visual Basic developer?

kenlin — Mon, 14 May 2007 20:24:00 GMT

At the Mix conference today in Las Vegas, Ray Ozzie and Scott Guthrie were dropping goodies like tootsie pops from a piñata. There was so much packed into their over two hour keynote that I thought it would be useful to distill the announcements down into one bite-sized post that should make for a pretty quick read (but unfortunately, includes no code samples.)

- VB on Silverlight – In short, this means that you can now use Visual Basic as the code-behind for whiz-bang rich interactive applications that run on Windows or the Mac and can run in IE, Firefox, and Safari. You can download the alpha .NET-enabled release but to develop you will need the Visual Studio Extensions for Silverlight for “Orcas” Beta1.

- Unparalleled support for dynamic languages – As you may have noticed us hinting at over the past couple of years now, VB has certain aspects to it that are dynamic – late binding, explicit member indexing, runtime conversions and operators, etc. With Silverlight comes the introduction of the DLR, a shared runtime component for dynamic languages atop .NET. There are many, many, things this means for VB that will unfold over the coming months, but one of the most important ones is that it will enable simple interoperability between Visual Basic and the other dynamic languages on .NET like Ruby, Python, and JScript. - Live Services – The Live Services team has created Windows Live in a Box that will allow you to begin integrating rich photo experiences, search, contacts and more into your applications. - Productivity Frameworks – Scott and Ray didn’t talk about this in their keynote, but with Mix comes a couple of new productivity frameworks. The first is Dynamic ASP.NET controls which uses runtime database schema and coding conventions to data-bind and generate ASP.NET pages. The second is “Jasper”, a dynamic data access layer that is independent of a presentation technology which sits atop the Entity Framework. We’re looking forward to seeing the reception for these kinds of frameworks.

So, that’s the two-bite version of the announcements… Over the next couple of weeks we’ll post new entries, videos, and samples demonstrating what each of these means in detail – though for some dirty details, you’ll have to wait for the PDC.

I’ll be at VSLive next week to talk about LINQ and Integrated XML in VB Orcas. I also have my turn for the webcast series for the VB LINQ deep dive and TechEd not that shortly after I get back – so I’ve got some work to do! Enough overview, back to coding!

"Live From Redmond" Webcast series

kenlin — Wed, 11 Apr 2007 19:08:00 GMT

VB Team is trying to get the word out about a Live From Redmond webcast series the VB team has put together aimed at Orcas and VB 9. The series will start April 18^th and will continue into June.

Finished the Translation on WF HOL Lab04 to VB2005

kenlin — Tue, 20 Mar 2007 20:46:00 GMT

Well, I start doing the translation again. I spent 2 days on this propose in the end of Jan. And I start pick it up again and try to finish it asap. Cause I found someone left message in wf.netfx2.com and asking me if I will do the rest. So....I hope that I would be able to finished all HOL Labs within this month. But it is a very hard job. I wake at 5:30am(because of Jet lag after back from Global MVP Summit 2007 in Seattle), I suppose should be wake up at 7:30am and go to an interview. I found nothing to do and so I still search around about Orcas, I got confuse on what Orcas acutally is. I know that it is Next VS(might be VS2007 with .NET Framework 3.5). But....I also found the Windows SDK for Vista are called Oracs_Mar07CTP in the description....hm....then....Orcas is including Windows SDK too? I then received email from the interviewer and said change the time to this Fri 8am. Cause the interview need to be fits with a Strong Tech Guy from Seattle. Yes...strong one, A guy who has 11yrs working experience, graduated from Harvard Uni.....

Anyway, I don't wanna get into sleep again, so I keep getting information from internet, and found, I have 3 things to do,

(1) Translation on WF HOL(Lab04 - Lab10);

(2) Translation on WF Starter Kit(still in beta and not released yet, so I think only WF team and I got it at this moment);

(3) Study Oracs, LINQ

(4) WF interact with WCF

Well, I found all I need the most is .....WF(cause K2 also is one of my interviewing company). And...I should start from basic first. So I found the first item I should choose is....(1). Then....should be (2). So I start my work on rest of Lab04. When I complete the Exercise 1 of Lab04, I cannot run it successfully. I search around and around, find many people saying that they have the same issues. I found many developers are trying to interact WF with ASP.NET2.0. But it is not a easy job but I think many companies(even in HK) will ask the developers to do so.

Well....until 3:30pm, I still cannot solve it. What happen to my VB one? C# is working and I just do the translation.....I take a rest and don't wanna think about it any more for a short time. I start my work again at about 10pm. I found there is a MSFT guy who answer a lot from this issue in MSDN forum, so I try to send him my source code and ask him if he can help. After I sent the email for 2-5 mins, a light comes up. I try to see my workflow project, get into every State and look at the HandleExternalEvent Activity. GOD! I made mistake on the Initial State. That is why the program cannot run it. Correct it and it works. Thanks god. And then I received that MSFT guy's email and telling me the same stupid thing I found. He is really good, within few minutes and he really do help me and found the point.

And now, it is 4:25am, all translation on Lab04 has done. Double check and the files can close. During today's translation, I found I have made mistake in my MSMVP's blog, http://msmvps.com/blogs/kenlin/archive/2007/01/31/convert-if-someevent-null-into-vb.aspx

In that blog, I mention, if C# is programming like

         if(SomeEvent != null)
         {
            SomeEvent(this, args);
         }

And VB should be

         if Not SomeEventEvent is Nothing Then
            SomeEventEvent(Me, args)
         End If

But....this is not true when apply to WF's State Machine Workflow, I have to make sure the event raise ONLY after the workflow runtime has really started. I have to change one property from the event arguments. So the code turns out like,

if Not SomeEventEvent is Nothing Then
args.WaitForIdle = true

SomeEventEvent(Me, args) 'Or "Raise Event SomeEvent(Me, args)
End If

But then you will found out that the program will fire another exception, it is saying (Event "{1}" on interface type "{0}" for instance id "{2}" cannot be delivered). Now you have to look deep into the InnerException and you will found ("Type {0} is not marked as serializable"). But you already given the serializable Attribute to the class. Why the exception is fired? It appears every parameter going into the event must be serializable, including the sender parameter! We pass this reference, which points to our payment processing service. The workflow instance doesn't actually need a reference to the testing service (if it needs to invoke a method on the service, it can use the CallExternalEvent activity), so we can fix this problem by leaving the sender parameter as null or Nothing. So finally, your code(with WF) will be like this,

if Not SomeEventEvent is Nothing Then
args.WaitForIdle = true

SomeEventEvent(Nothing, args) 'Or "Raise Event SomeEvent(Nothing, args)
End If

Convert (If (SomeEvent != null)) into VB

kenlin — Wed, 31 Jan 2007 02:40:00 GMT

As I said yesterday, I translated 3 labs on official WF HOLs from C# to VB2005. Today I start the lab04, I found out that there are some code that I cannot find a way to make it work in VB. So I start searching and found the following result in http://www.codeproject.com/vb/net/backgroundworker.asp . Following what he said and the code now is working.

==========================================================================================

This was not without its quirks.

The best practice for raising events tells us that we should always test that the event is not null before raising the event. That is to say, the event must have handlers. All the articles then give a code sample something like this:

         if(SomeEvent != null)
         {
            SomeEvent(this, args);
         }

The C# implementations of BackgroundWorker both used this standard. But how do I do that in VB.NET? If you try the statement SomeEvent != Nothing, you get the error: 'Public Event SomeEvent(sender As Object, e As System.EventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event. Not very useful!

It turns out that in VB.NET, to get at the delegate derived object to test if it is Nothing, you just add "Event" to the end of the event name. Don't go looking for it in intellisense though, because it won't be there! The resulting VB.NET code is:

         if Not SomeEventEvent is Nothing Then
            SomeEventEvent(Me, args)
         End If

Why have I used SomeEventEvent(Me, args) instead of RaiseEvent SomeEvent(Me, args)?

The default method of a delegate is the Invoke method, and RaiseEvent in VB.NET just calls this method on the delegate, and it makes my code less language specific. Personal preference really.

Windows Workflow Foundation(WF) Hands-On Lab01 to Lab03 in VB2005

kenlin — Tue, 30 Jan 2007 06:04:00 GMT

If you are interesting in Windows Workflow Foundation(WF), you should found only C# hands-On Lab. A good news to you, I tried to translated them into VB2005, and it was tested by WF Team and now, you may download them from the following link, the full story are here...

I have 2 entries on the translation of WF, one is including Lab01, while another one is including Lab01-Lab03, they are both top 5 download in http://www.netfx3.com/

===========================================================

The Windows Workflow Foundation (WF) runtime supports all CLS compliant programming languages. The Visual Studio 2005 extensions for WF are only provided for C# and Visual Basic .NET. It's easy to find C# samples to get started. Here's some pointers to samples for getting started with Windows Workflow Foundation in Visual Basic .NET.
