What’s New in Windows Mobile 6.5 :
Developer Tools :
Windows Mobile 6 SDK
Windows Mobile 6.5 DTK
Visual Studio 2008
Windows Mobile Device Center (Windows Vista and above versions)
Active Sync (Windows XP and earlier versions)
My First Application :
Step 1 : Choose a Proramming Language
Visual C++ (Native coding language)
Visual C# /VB.Net (Managed Coding)
Client Side – JScript
Server Side – Asp.Net
Step 2 : Select the template
Choose “Device Application”
Step 3 : Run and Debug the application
Step 4 : Save the state of the emulator
Useful for saving your own configuration for any type of Device Emulator
Once you have completed your setting Save the State by selecting Save and Exit in the File Menu in Device Emulator
A saved state file contains all RAM, ROM, and settings information from the Device Emulator.
It has the extension .dess (Device Emulator Saved State)
The .dess file is the only file necessary to restore a saved state.
The .dess extension is registered at setup, so double-clicking a .dess file launches the Device Emulator with the state saved in that file
You can find the .dess file @
C:\Users\Darnie\AppData\Roaming\Microsoft\Device Emulator
The state of the Emulator is saved in VMID (Virtual Machine Identifier) with a .dess extension
Launching a Emulator From Visual Studio 2008 :
Tools -> Connect to Device
Tools – > Device Emulator Manager
Launching the Device Emulator as a Stand alone application
dvcemumanager.exe
Launching the Device Emulator from Command Line
DeviceEmulator.exe
Steps to Use GPS Intermediate Driver in Managed Code :
Step 1 : Upgrade the Sample Application
The Sample Application is Written in VS2005 therefor upgrade and buid the solution
Step 2 : Add reference to the GPS application
Microsft.WindowsMobile.Samples.Location
Call the Classes in your project thru “Using”
using Microsoft.WindowsMobile.Samples.Location;
Once you have added reference the GpsDeviceState and GpsPosition helper object store data about you current location
Step 3 : Create a gps object for the class Gps and initialize the helper objects.
Gps gps = new Gps();
GpsDeviceState device = null;
GpsPosition position = null;
Step 4 : Add event handlers for the DeviceStateChanged and LocationChanged events of the Gps object
updateDataHandler = new System.EventHandler(UpdateData);
gps.DeviceStateChanged += new Microsoft.WindowsMobile.Samples.
Location.DeviceStateChangedEventHandler(gps_DeviceStateChanged);
gps.LocationChanged += new Microsoft.WindowsMobile.Samples.
Location.LocationChangedEventHandler(gps_LocationChanged);
Step 5 : Implement the Event Handlers and in the implementation part call the Invoke to trigger an Event and call the UpdateDataHandler
protected void gps_LocationChanged(object sender,
LocationChangedEventArgs args)
{
position = args.Position;
Invoke(updateDataHandler);
}
Step 6 : Inside the UpdateDataHandler receive the latitude and longitude values and display it.
void UpdateData(object sender, System.EventArgs args)
{
if (gps.Opened)
{
// verify that the device object is not null
if (device != null)
{
// display device status
StatusLabel.Text = device.FriendlyName + “Status: ” +
device.ServiceState + “, ” + device.DeviceState;
}
// verify that the position object is not null
if (position != null)
{
//The position object exposes
// additional properties that indicate
//which properties are currently valid.
if (position.LatitudeValid)
{
// display latitude
LatitudeLabel.Text = “Latitude(D,M,S): ” +
position.LatitudeInDegreesMinutesSeconds;
}
