This code sample is named PhoneFinder. It demonstrates how to write an application that helps you locate your phone if you lose it.
Navigate to the solution file (*.sln), and double-click it. By default, the solution files are copied to the following folders:
C:\Program Files\Windows Mobile 6.5.3 DTK\Samples\Smartphone\CS\PhoneFinder
C:\Program Files\Windows Mobile 6.5.3 DTK\Samples\Smartphone\VB\PhoneFinder
Microsoft Visual Studio launches and loads the solution.
Build the solution (Ctrl+Shift+B).
Deploy the solution (F5).
If you have not installed the SampleUnprivDevelopercertificate, you will need to so that your DLL and CAB projects are signed correctly
Click Start> Run.
Type the path-name to SampleUnprivDeveloper.pfxcertificate, and click OK. By default, this is located in the following folder:
C:\Program Files\Windows Mobile 6.5.3 DTK\Tools\Security\SDK Development Certificates\
Double-click the SampleUnprivDeveloper.pfxcertificate icon. The Certificate Import Wizard appears.
Click Next. The certificate path-name is filled-in.
Click Next(you do not need a password).
Click Next. Accept the default options; automatically select the certificate store based on certificate type.
9. Click Finish.
See Mobile device Security Modelfor further details on how to install the SDK certificates onto the mobile device, and how to use the privileged SDK certificate to sign this application.
Using the application
- When you run the application, you have the option of setting a
PIN and enabling or disabling
- To activate
PhoneFinder, send a text message from any cell phone to your
phone. Enter Only the PIN in the body of the text message.
- If enabled, your phone will wake up and start playing a sound.
While playing the sound, it will also display your Owner
Information so that if someone else finds your phone, they can
figure out how to contact you.
- SMS interception is used to raise an event when your PIN is
sent to the phone via a text message, and the
Notifications Brokeris used to retrieve the Owner Information
if it exists.
- To play the sound, the sample uses
PInvoketo call the native API, PlaySound, which plays the sound even if your Microsoft.WindowsMobile.Status.SystemState.PhoneProfileis set to Silent, making it very useful if you lose your phone while set to Silent.
It is assumed that your Windows Mobile Standard can receive SMS text messages.
This code sample runs as an standard API. Applications that use it must be signed with an standard certificate.
SDK:Windows Mobile Professional SDK and Windows Mobile Standard SDK
Development Environment:Visual Studio 2005 or 2008.
