Tip: How to know the OS version of your Windows Mobile device
Dim OS As OperatingSystem
OS = Environment.OSVersion
MsgBox(OS.ToString)
Tip: How to programmatically check the orientation of your Windows Mobile device
Dim o As Orientation = Microsoft.WindowsCE.Forms.SystemSettings.ScreenOrientation
MsgBox(o.ToString)

Tip: Missing controls in Toolbox - Visual Studio 2008
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
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 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

New book - Professional Windows Vista Gadgets Programming
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.

Developing a File Explorer for the Smartphone Using the .NET Compact Framework
Here is the synopsis of that article:
"Unlike the Pocket PC, the Smartphone 2003 platform does not come with a File Explorer for users to view the folders (and files) on the phone. This is perhaps due to the fact that Microsoft does not see the need for users to do this. However, it is often useful for developers to be able to view the directory structure of a Smartphone so that they can decide on which folders to use to store their applications and files. In this article, I will demonstrate how you can build a File Explorer for your Smartphone using the .NET Compact Framework. You will need to have Microsoft Visual Studio .NET 2003 and the Smartphone 2003 SDK to do this. "

Want to build your own phone applications?
In this two-day workshop, you will build a SMS Manager application that allows you to use SMS message for voting purposes. This application is useful in scenarios where you need to collect feedback from users realtime, and is very useful in places like lecture threatres where you want to encourage students' participations.
In addition, you will also build a Call Manager application. The Call Manager allows you to disable your phone calls when you are driving or in a meeting and automatically sends a message to inform the caller that you are unable to take the call (if it is your boss calling, send him/her a message that you are now very busy with work to take his/her call!).
If you have a Windows Mobile 5.0 phone edition device and want to know what are the things you can do to make it more useful (well, build the applications yourself!), join us this Sep 20th and 21st. For more information, contact me at weimenglee@learn2develop.net.

Some Frequently Asked Questions (FAQ) About My Courses
Do I need to bring my own Pocket PC device for the course?
No, Pocket PCs will be provided (you have to share them though). Symbol will be providing 10 units of the MC70 for testing purpose, as well as other accessories such as RFID snap-ons, GPS receiver, as well as Zebra Bluetooth Printers. However, please feel free to bring your own device if you want to see how the sample apps run on your own device.
I have a older Windows Mobile 2003 PPC. Is this course applicable?
While this course is focused on Windows Mobile 5.0, there are some examples that will work on older PPCs. For example, the SerialPort class is new in .NET CF 2.0 and hence it is not tied to the Windows Mobile 5.0 platform, and therefore will work on older PPCs.
How is your course different from others?
If you have attended my course before, you would know that I am a great believer of learning-by-doing. And hence my course is focused extensively on hands-ons. I don't believe in spending lots of time on slides, explaining all the details of a class/methods. For that, you can really read a book or documentation.
I believe that the best way to learn programming is to actually type in the code, debug it, fix it and then seeing the end result yourself. In fact, I encourage my students to make as much mistakes as possible so that the concepts really sink in into their heads (this is actually how I learn new technologies; and in fact the best way to learn a new technology is to write a book! :-)).
And of course, the key ingredient to a good course is the course materials/workbook. For all my courses, I use materials that I develop myself. Each lab exercises contains simple and practical demos that you can modify and use for your own projects. I do not believe in huge and complicated examples/case studies that require you to start in Day 1 and complete in Day 5. As far as possible, each lab exercise is stand-alone so that students who did not manage to follow earlier labs (either they are late or the topics are just not relevant to them) can follow the rest of the course without feeling lost. In fact, I eat my own dog-food - I always refer to my own course materials when I am working on projects and needed to quickly locate a code-snippet to accomplish some functions, such as how to serialize a class, encrypt some text strings, access database, etc.
That said, do send in your questions if you have any. Cheers!
