View your WP7 App’s Isolated Storage Structure (with source code)

Working with the Isolated Storage within the Windows Phone 7 emulator can be quite tricky. Firstly, there are often exceptions thrown that don’t always explain what the root cause of the error is. Secondly, it’s often difficult to figure out the structure of your Isolated Storage, especially as more directories and files are created. Therefore, I decided to write a quick class (IsoViewer.cs) which makes it easier to get an overview of the structure of your Isolated Storage.

Use your webcam with the WP7 Emulator (with code!)

The GPS Simulator seemed pretty popular with many developers and whilst I was browsing through various forums, I noticed the request for webcam usage as the emulator’s camera. In an earlier project (using the April CTP), I needed to be able to use the webcam as well as the ability to use images from within the application. The latter spawned the Testing Photos with WP7 Emulator post, but I could see no way to use my webcam as the camera. Well now (literally 10 minutes after coming up with the idea – that’s what happens when you have awesome dev tools ;)), I simply re-factored the GPS Sim code and have it working for a webcam instead of Bing maps. What PicSim allows you to do is to use your webcam to capture an image and then immediately have that image streamed over to your WP7 application, as well as other images stored on your computer. You can download the source code and see a screenshot below.

No Device? No GPS? No Matter! – (With Code!)

Necessity is the mother of all invention and so I went about creating a quick application to better help simulate GPS coordinates when developing for WP7. Most developers don’t have a test device and two common reasons for asking for one is for the GPS and for the accelerometer. The latter has been simulated quite well (via the HTC HD2 or the Wiimote), but the former is usually simulated by manually typing in (or downloading a set of) coordinates. I’m currently reading up on WCF and decided to kill two birds with one stone – learn WCF and help other developers.

So, what is it? Simple – A locally hosted server displaying Bing maps and a client (e.g. your WP7 app) consuming those coordinates. As you move your mouse along the map, the GPS coordinates are retrieved and sent to the phone. This opens up quite a few possibilities. For example, you could store the coordinates every X seconds  in a list to generate a ‘path’ that simulates someone driving from one point to another. If you need to know exact coordinates for your application, you can also extend the app so that you can  press a key whenever you want to store a particular coordinate. Whatever you use it for, hopefully it saves you time and makes it easier to develop the GPS aspects of your application. Check out the video and source code below.

ICE Alert Application Update for WP7 (Mine!)

ICE ALERT CAN NOW BE DOWNLOADED FOR FREE. CHECK OUT THE NEW VIDEO AND DOWNLOAD HERE AT THE OFFICIAL SITE.

Information Update: ICE App currently in Marketplace is not mine

I was going to record another video for the latest version of my ICE application (updated to ICE Alert since it merges the ICE application with the Panic Alert application). However, it turns out that the the presentation I did at the Windows Phone 7 User Group was recorded and so I’ll show that :).

ICE Alert is an application for Windows Phone 7 which makes it easier for first respondents such as paramedics to get information about you. For example, if you’re involved in an accident, the paramedic can see who they should contact first, what conditions you suffer from, what medications you take, allergies etc… It also allows you to customise the Panic Alert button to  instantly set up a text message to send to a list of predefined friends with a predefined message (including automatic appendage of GPS coordinates), instantly set up a call with a certain contact/emergency services or allows you to record a message quickly that you would like to pass to a first respondent in order to save them crucial time figuring out what happened to you. It will be a free download for Windows Phone 7.

Check out the video of my presentation below, demonstrating the latest version of ICE Alert.

Panic Alert App for WP7 (Mine!)

ICE ALERT CAN NOW BE DOWNLOADED FOR FREE. CHECK OUT THE NEW VIDEO AND DOWNLOAD HERE AT THE OFFICIAL SITE.

Update (30/07) – Latest version of Panic Alert – click here

Hey everyone,

I got some great feedback via comments and emails regarding my ICE application. If you saw the ICE app video, you would’ve heard me discuss another health and safety application I was working on. Due to the feedback I received from the ICE app, I decided to take a different approach to the development of my other application. The application is called Panic Alert and the video shows a quick prototype of it working. The reason I released an early video is because I feel it would be interesting to get ideas and feedback at an early stage in development so that new suggestions can be incorporated from the beginning.

Unlike ICE, the application is designed to be used by the owner. When they feel unsafe, or are in danger, they can easily perform three key actions.

1) Quickly set up a call to emergency services

2) Quickly set up a call to a chosen contact

3) Quickly set up a text message containing a predefined message and GPS coordinates

These actions could prove vital in an emergency situation. Check out the video below and feel free to send in feedback.

Update (30/07): Check out the latest version of ICE – click here

Information Update: ICE App currently in Marketplace is not mine

Hey everyone,

I’ve been posting videos I’ve received in the showcase area. I decided to create a video of an application I made called ICE (which stands for In case of Emergency). Should the owner of this app get into an accident, a paramedic could launch the ICE app and see details of the owner (e.g. ICE Contacts/Medications/Allergies/Conditions) very quickly and easily. This information could prove crucial in an emergency situation.  It’s still in development (waiting for an SDK update) and will be made available completely free of charge in Windows Marketplace when WP7 launches. Check out the video below and let me know what you think of it so far (comment on this post/YouTube, email me or message me on Twitter).
