New language on the block - KPL (Kids Programming Language)

From TechWeb:

"Microsoft has signed on to promote a new programming language intended to replace BASIC as the first step students take towards learning how to code. The Kid's Programming Language, or KPL, was developed under the direction of Jonah Stagner, and his colleagues, ex-Microsoft program manager Jon Schwartz and former NCR engineer Walt Morrison. The three run the software consultancy Morrison-Schwartz Inc. "

You can download KPL from: http://www.kidsprogramminglanguage.com/download.htm

Here is a screenshot of the KPL IDE:

One cool feature is that you can directly translate KPL code into C# and VB.NET, making KPL a very good language for getting kids started on programming and then eventually moving into .NET programming using C# or VB.NET:

Sample projects for Visual Basic 2005 Jumpstart (O'Reilly)

Some readers wrote in and asked if the code samples for my Visual Basic 2005 Jumpstart is available for download. Yes, it is now available at this O'Reilly site (click on the Examples link). The two sample projects include a Windows application called LibraryApp that allows you to keep track of your libary of books. It connects to Amazon.com web service and pulls information down to your computer. Hey, if you connect a barcode scanner to your computer, this app can actually automatically build your own library system, complete with book covers and detailed book information. Way cool!

The second app shows how to build a simple shopping cart application using the new features in ASP.NET 2.0. Shows quite a number of features - Master pages, Profile services, etc.

Check them out (even if you don't have the book)!

Writing A Custom Membership Provider for your ASP.NET 2.0 Web Site

If you have an ASP.NET Web site that stores any registration or log in information for your users, you probably know that the Membership provider in ASP.NET 2.0 uses a SQL Server Express 2005 database. But what if you want to use something else? This article will show you to use your own data source for storing membership information.

Visual Basic 2005 Jumpstart Published!

I just received my advance copy of the Visual Basic 2005 Jumpstart today; looks very good and feels great!. This is a book that I spent a good five-month working on, rewriting a couple of times to ensure that it is not only useful to beginning VB programmers, but more importantly it should be a effective jumpstart for VB6 programmers. I had the honor of working with Jay Roxe (Product Manager of Visual Basic at Microsoft), who provided a lot of feedbacks and advice for the book. If you are new to Visual Basic and want to work on the .NET platform, give it a look and let me know what you think of it.

Thanks to the various technical reviewers and advisors - Robert Green (formerly Visual Basic team at Microsoft), Jeff Barr (Amazon.com), Paul Yuknewicz (Microsoft), and Joseph Binder (Microsoft).

The new iPod nano

Apple has just released the incredibly small and pencil-thin iPod nano. With a 1.5-inch (diagonal) color LCD with LED backlight and weighing a mere 1.5 ounces, the new iPod nano comes in two versions - 2GB (US$199) and 4GB(US$249). There are also two colors to choose from - White and Black. Enough said, check it out yourself!

WinFS StoreSpy

If you recently downloaded the Beta 1 bits of WinFS, then you really need to try out the included WinFS StoreSpy application. Using StoreSpy, you could easily search for files stored in your WinFS stores by executing queries against it.

Using Your Webcam for Surveillance

Webcams are useful for videoconferencing, but videoconferencing has not really caught on. So if you own a webcam, you know that most of the time it is lying around gathering dust. But if you have a webcam, you can put it to better use than videoconferencing. In this article, I will show you how you can set up your webcam as a surveillance system using the appropriate hardware and software.

Avalon Programming on Windows XP

I did a session on "Building Windows Vista (Longhorn) client application using Avalon" today at TechEd '05 Singapore. If you are interested to test out Avalon today, you simply need to have Windows XP, together with the following free downloads from Microsoft:

• Microsoft® WinFX™ Software Development Kit for Microsoft® Pre-Release Windows Operating System Code-Named "Longhorn", Beta 1 Web Setup
• Microsoft® Pre-Release Software WinFX Runtime Components Beta1

In addition, to help you create Avalon UI using XAML, you can try out the following third-party tools:

• ZAM 3D
• Aurora XAML Designer

Have fun!

Changes in Client Callback in Visual Studio 2005 July CTP

If you use the July CTP of Visual Studio 2005, you might have noticed that the RaiseCallbackEvent event (in the ICallbackEventHandler interface) has now been split into two separate events:

• PrepareCallbackEvent


• RenderCallbackResult

That means that the Client Callback example in my book - ASP.NET 2.0: A Developer’s Notebook, will break. Fortunately, a reader named Cindy Kee alerted me to the problem and helped to change the code listed on page 266 and 267 of the book to use the two new events. Here they are, in C#:

void ICallbackEventHandler.PrepareCallbackEvent(string eventArgument)
{
this._eventArg = eventArgument;
}

string ICallbackEventHandler.RenderCallbackResult()
{
if (this._eventArg.StartsWith("1:"))
{
//--strips away the command
this._eventArg = this._eventArg.Substring(2);
//--get city and state based on Zipcode
switch (this._eventArg)
{
case "95472":
return "Sebastopol,CA";
case "02140":
return "Cambridge,MA";
default:
throw (new Exception("ZipCode not valid!"));
}
}
else if (this._eventArg.StartsWith("2:"))
{
//--strips away the command
this._eventArg = this._eventArg.Substring(2);
//--get states and cities related to country
switch (this._eventArg)
{
case "Sing":
return "Singapore,";
case "US":
return "Alabama,California,Maryland,Massachusetts,New York,Oklahoma,Wisconsin,";
case "UK":
return "Birmingham,Cambridge,Christchurch,Leeds,Sheffield,";
default:
return "";
}
}
else
{
return "Command not recognized";
}
}

In essence, the two events above replace the original function that handled the RaiseCallbackEvent event. The rationale for the changes is to ensure callbacks work with asynchronous data sources.

For VB2005 readers, it should not be difficult to modify the original code in the book. Thanks, Cindy, for pointing that out to me!

Blogger for Word Add-in

Google has just announced the release of the Blogger for Word Add-in that allows users to publish their post in Blogger.com via Microsoft Word. Using the Blogger for Word Add-in, you will be able use Microsoft Word to:

• Publish to your blog
• Save drafts
• Edit posts
  

I have tried it and it works pretty neat! However, my only complain is that it can’t handle images yet and I still have to edit my post using Blogger Dashboard.

Avalon series

I recently did a three-part article series on Avalon (now officially known as Windows Presentation Foundation, or WPF for short) for DevX.com. Part 1 talks about the basics of XAML (the UI markup language for Avalon applications) and Part 2 talks about the navigational topology in Avalon applications. If you are interested in developing application for the upcoming Windows Vista, do check them out and be in the know of what is to come. Note that the articles were all based on Beta 1 of the WinFX SDK, and hence they are not guaranteed to be valid in the final release.

iPod Photo

When Apple first released the iPod Photo in late 2004, I was one of the first to order one, in addition to the third generation 20GB iPod I already have. I was intrigued with the fact that you can display photos and album artworks with the iPod photo and perhaps with some hacks you can play movies with it (no one really managed to do it, but close).

That prompted me to write the eDoc - All About Your iPod Photo (PDF), for O'Reilly. In it, I shared some of the ways in which you can:

• Save photos for viewing on a TV
• Use it for presenting PowerPoint slides
• View photo slideshows with background music
• View and listen to Podcast

However, recently Apple has decided to put color screens on every iPod, meaning that all new iPods you buy today are essentially iPod photos. This further proves that color is a necessity for the iPod and that a separate line of iPod with color capabilities does not justify the higher price tag (at least consumers would not be willing to pay for it).

Nevertheless, my eDoc is still useful if you have a color iPod :-) It is available as a PDF file for US$5.95. I am not sure if people are willing to folk out cash for buying bytes, but do let me know if you have reached the stage where you buy books based on content rather than on something physical.

An In-Depth Look at Vista, Part 1 and 2

Microsoft has recently released Windows Vista (formerly codenamed Longhorn) Beta 1. These two articles (Part 1 and Part 2) on WindowsDevCenter.com detailed some of the new features in this new OS.

Missing Generate Local Resource menu item in Visual Studio 2005?

Some of you have pointed out to me that when doing localization for your ASP.NET 2.0 web application, you could not locate the Generate Local Resource menu item under the Tools menu in Visual Studio 2005.

While I do not know the exact cause of the missing menu item (probably it went missing after you install some third-party tools in Visual Studio 2005). However, you can get it back easily. Here are the steps:

Go to Tools->Customize.

Select the Tools catagory and click on the “Rearrange Commands…” button.

In the Menu Bar list, select Tools and click Add… to add the Generate Local Resource menu item.

That should add the Generate Local Resource menu item back into the Tools menu.

Tabbed browsing, RSS support, and more

My first look at Microsoft Internet Explorer 7 (IE7) Beta 1. This is the version that comes with Windows Vista Beta 1. If you are a big-fan of tabbed-browsing, then IE7 should be good news to you. Also, RSS support is built-in. However, do not expect all the niceties to be in this Beta 1.
