Playing with Media in Silverlight 1.0

Waiting for Silverlight to deliver on it's promise of delivering rich media experiences? Take your first steps with this tutorial on how to embed a Windows media file in your Silverlight application, control its playback, and create simple effects on the video.

Tip: How to know the OS version of your Windows Mobile device

You can use the OSVersion property from the Environment class to obtain the OS version number of your Windows Mobile device, like this:

Dim OS As OperatingSystem
OS = Environment.OSVersion
MsgBox(OS.ToString)

Tip: How to programmatically check the orientation of your Windows Mobile device

In the past, I always compare the value of Me.Width and Me.Height (within a Form window) to determine the orientation mode of my Windows Mobile device. Besides this method, you can also use the ScreenOrientation property available in the SystemSettings class in the Microsoft.WindowsCE.Forms.dll, like this:

Dim o As Orientation = Microsoft.WindowsCE.Forms.SystemSettings.ScreenOrientation
MsgBox(o.ToString)

For portrait mode, it returns Horizontal. For landscape mode, it returns Vertical.

Tip: Missing controls in Toolbox - Visual Studio 2008

I encountered a problem today when I uninstalled my Visual Studio 2008 Beta 2 and then installed the RTM version of Visual Studio 2008 Professional.

When I created a Windows Mobile project, the controls in Toolbox were missing. In place of the usual controls is a tab labelled "#13119". The usual remedy of right-clicking the Toolbox and then selecting Reset Toolbox did not help.

After some searching of Visual Studio folders, I finally found the solution. You need to navigate to the following folder:

C:\Documents and Settings\\Local Settings\Application Data\Microsoft\VisualStudio\9.0

And within this folder are some hidden files. Simply remove the following files:

"toolbox.tbd", "toolboxIndex.tbd", "toolbox_reset.tbd", "toolboxIndex_reset.tbd"

Then restart Visual Studio 2008. Your controls should now come back up! ;-)

Developing "Touch" UI for Windows Mobile

Unless you have been hiding in the mountains for the last couple of months, you must have heard of (and even experienced) the revolutionary "touch" interface of Apple's iPhone and iPod Touch. And that leaves the rest of us wanting that feature for our phones (Windows Mobile, Symbian, etc).

While the HTC Touch fills that void by supporting a touch UI, it requires people to buy a new device, which most of us do not have the luxury of doing so. So what to do if you have a Windows Mobile 5.0/6 device and are keen to develop applications that support the "touch" UI? Well, come and join us in the upcoming Windows Mobile 6 Programming course and I will show you the techniques to develop "touch"-enabled applications that allow users to navigate your application using their fingers. And best of all, these techniques work across all Windows Mobile devices.

Check out the course details here.

Tip: How to get IP address of your Windows Mobile device

Question:
How do I know if my Windows Mobile device is connected to the Internet and if so, what is its IP address?
Answer:
Use the following function to determine if you are connected. You can also use this to determine its IP address:

'---check whether you are connected to the Internet---
Private Function IsConnected() As Boolean
   Try
      Dim hostName As String = Dns.GetHostName()
      Dim currenthost As IPHostEntry = Dns.GetHostEntry(hostName)
      Return currenthost.AddressList(0).ToString() <> _
      IPAddress.Loopback.ToString()
   Catch ex As Exception
      Return False
   End Try
End Function

Crocs shoes and Apple

OK, I am going to confess that I am quite a fan of Croc shoes....and today I got my second pair of the Crocs islander. If you have never worn a pair of Crocs before, I know what you must be thinking now... "boy....that color/design is really weird....are you sure you dare to wear this out....?".

Well, wait till you try your feet on a pair of Crocs and you will know how comfortable it feels. It is virtually weightless and feels like ... er ... you are not wearing any shoes! And depending on your taste, there is always a color/design that suits you.

But wait....why am I talking about shoes in a technology blog? If you look at Crocs and Apple, both companies seem to have something in common.....underdogs in an industry where both do not have the majority market share...and yet they continue to innovate by focusing on design and quality. I have always liked to walk into a Crocs showroom and be facinated with new designs that make me think: "why didn't I think of that!" Likewise, Apple's attention to details and usability have always been their trademark.

And if you are still with me ... both companies are great inspirations for me to develop courses that are fun, informative, and most importantly, effective for you to learn new technologies in the shortest amount of time. And if you have never attended any of my classes, I would like to invite you, just like Crocs who in the early days asked customers, to give it a try and experience it themselves. Go on, pick a design (course) and see if you like it. :-)

Geo-tag Your Photos Using ASP.NET and Google Maps: Part II - Upload, Tag, Save, and Retrieve Photos

The Google Maps API is a free mapping service that allows you to embed maps into your Web pages using JavaScript. Google Maps also provides the ability for you to insert markers at landmarks of interest. You can use this feature to associate photos with different geographical locations — a process known as geo-tagging. I conclude my two-part series by extending the project created in Part I so users can upload photos to it and geo-tag each photo.

Using the Smart Device Framework for Windows Mobile Development

The .NET Compact Framework's class libraries are sadly inadequate for developing full-featured Windows Mobile applications, sometimes forcing you to rely upon the problematic Platform Invoke. Enter Smart Device Framework (SDF), a group of extensions designed to pick up where the Compact Framework's class libraries leave off.

iPod Vending Machine in San Francisco

And before you regain your sanity, you will be busy swiping your credit card and reaching to pick up the iPod that has magically appeared in the little window...

New book - Professional Windows Vista Gadgets Programming

I am extremely excited to announce that my new book - Professional Windows Vista Gadgets Programming (Wrox) is on track to be released in Dec 07. I have worked hard to make this book a useful resource for developers building Windows Sidebar and SideShow gadgets.

Check out the following for the synopsis and head to Amazon.com to reserve your copy today!

As an easy-to-use application that provides information at a glance, a gadget basically takes the concept of portal dashboards and moves them to the more accessible Windows desktop where users can quickly and easily obtain weather information, RSS news feeds, and much more. In Windows Vista, there are two types of gadgets – Sidebar and SideShow gadgets. Sidebar gadgets are mini applications hosted in the Sidebar pane located on the Windows desktop, while SideShow gadgets are applications that send information to SideShow-enabled devices such as an external LCD display, or even a remote control.

With this hands-on guide, you’ll discover the simplicity of developing Vista Sidebar and SideShow gadgets that can run on the Windows desktop as well as send information to SideShow-enabled devices.

This book contains two parts – the first covers Sidebar gadgets while the second part covers SideShow gadgets. In each part, Microsoft MVP author Wei-Meng Lee begins by walking you through the development of a simple gadget, introducing you to the key concepts in the process. Each chapter breaks down the specific APIs that are relevant to enhancing a gadget, and helpful code samples throughout every chapter detail the step-by-step progression of how a gadget is built. By the end of the book, you will be confidently programming Vista gadgets.

What you will learn from this book
* Components of a Sidebar gadget
* Detailed description and code samples on using the Sidebar APIs
* Using .NET Interop to enhance Sidebar gadgets
* Interfacing Sidebar gadgets with SideShow-enabled devices
* Localizing Sidebar gadgets
* Debugging Sidebar gadgets
* Detailed walk through of a Sidebar gadget project
* SideShow architecture
* Using the SideShow managed class for .NET development
* Understanding the Simple Content Format (SCF) content format for sending SideShow data
* Interacting with SideShow-enabled device
* Detailed walk through of a SideShow gadget project

Who this book is for
This book is for developers who want to build Windows Vista gadgets that target both the desktop as well as SideShow-enabled devices.
