Do you need help with your Windows Mobile project? MSDN have two forums for SmartDevices, one for managed development and one for native, check them out below for help with issues or to see what problems other people are facing.

Windows Live Search client for Windows Mobile

wigunara — Sun, 14 Jan 2007 22:19:00 GMT

If you have a Windows Mobile device you need this! It's neat, it has road and arial maps, driving directions (with GPS support) and "find my nearest" functionality.

From your Windows Mobile device or J2ME enabled device go to

http://wls.live.com

and download the Windows Live Search application for mobile devices.

Thanks to all those who attended my sessions at TechEd. As promised in my SQL Mobile session here is the source for a very simpler timer class to help you monitor performance.

using System;

using System.Collections.Generic;

using System.Windows.Forms;

using System.Runtime.InteropServices;

namespace Timer

{

public class TestTimer

{

[DllImport("CoreDll.dll")]

public static extern int QueryPerformanceFrequency

(

ref Int64 lpFrequency

);

[DllImport("CoreDll.dll")]

public static extern int QueryPerformanceCounter

(

ref Int64 lpPerformanceCount

);

System.Int64 freq = 0;

public TestTimer()

{

QueryPerformanceFrequency(ref freq);

}

public delegate void timerResult(string msg,System.Int64 time);

public event timerResult OnTimerResult;

private System.Int64 _startTime = 0 ;

private System.Int64 _lastReading = 0;

public bool TimerSupported

{

get

{

bool result = true;

if (QueryPerformanceFrequency(ref freq) == 0)

result = false;

System.Int64 testCounter = 0;

if (QueryPerformanceCounter(ref testCounter) == 0)

result = false;

return (result);

}

public void Start()

{

QueryPerformanceCounter(ref _startTime);

_lastReading = _startTime;

}

public void TakeReading(string msg)

{

System.Int64 _takeReading = 0;

QueryPerformanceCounter(ref _takeReading);

System.Int64 time_ms = (_takeReading - _lastReading) * 1000 / freq;

_lastReading = _takeReading;

if (OnTimerResult!=null)

OnTimerResult(msg,time_ms);

}

public void TotalTime(string msg)

{

_lastReading = _startTime;

TakeReading(msg);

}

Windows Mobile, SQL Mobile 2005 and .NET Compact Framework 2.0 - a powerful combination

wigunara — Fri, 10 Mar 2006 03:01:00 GMT

I want to share with you the enthusiasm I have for the Windows Mobile platform. If I had to pick an area of innovation that excited me most last year, it would have to be the developments in the Windows Mobile space. Windows and SQL Mobile 2005 in conjunction with the .NET Compact Framework 2.0 form an incredibly powerful platform for mobile information workers.

How many of you have a Windows Mobile powered device - a PDA or Smartphone?

Did you know you could get SQL Mobile for your Windows Mobile device?

Did you know that SQL Mobile can be a merge replication subscriber for data from your backend SQL Server 2000 or 2005 databases?

Now imagine what you could do with that? Any data stored in a SQL Server database could be made available to a Windows Mobile equipped workforce.

Obviously in order to do anything meaninful with that data you need a front-end application on the PDA or Smartphone, that's where the .NET Compact Framework 2.0 comes in handy.

Changes to the data on the mobile device are synchronised with SQL Server when replication is triggered and a flexible conflict resolution system is on hand should the complexity of your solution require it.
