Google Talk (beta)
Google has just joined the Instant Messaging market with the new Google Talk (beta). Using the Google Talk, not only can you send instant messages to your friends, you can also participate in voice calls, for free. I have not tried the voice call feature yet, but if you want to try it out, call me at weimenglee@gmail.com. :-)

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:
Have fun!

Changes in Client Callback in Visual Studio 2005 July CTP
- PrepareCallbackEvent
- RenderCallbackResult
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.

Missing Generate Local Resource menu item 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.
Allow your users to use your website in their own language
Globalization and Localization support is much improved in ASP.NET 2.0. If you are into writing international web applications, check out my article on ONDotNnet.com.
Tabbed browsing, RSS support, and more
. 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.
