WM6天气预报程序的开发

去年换了个智能手机，虽然很山寨，但是还蛮喜欢的。不停的刷机，装各种软件，从WM5到WM6，熟悉之后，就没了新鲜感，感觉电话吗，也就是个电话，老折腾这个干嘛。但是确实离不了了，跟LP换了一段手机使用，那段时间简直是煎熬，找电话不方便，查个什么资料也不方便，没几天就换回来了。看来真是离不开智能手机了。

     手机上一直装的软件就是天气预报，从SPBWeather，到天气秀，再到天气小秘，有的数据源不稳定，三天两头的无法更新，有的界面太烦琐，额这个人就喜欢清爽点的，过年在家有空，研究了一下，装了WM SDK和模拟器，就自己动手了。做完后一直很忙，没放上来，现在补上。

     先看个界面，这是桌面插件：（QuickWeather.dll,VS2005,C++）

 

这个是后台管理程序（PPCQuickWeather.exe,.net）

 

 

主要实现的功能：

1、在桌面显示最近三天的天气信息；

2、可以每天进行两次天气自动更新；

3、可手动更新天气信息；

4、附带手机时间同步，与time.nist.gov同步。

 

主要用到的技术：

1、使用WebService获得天气数据信息；

这个在.net里没有什么难的，在WM系统里和普通的系统里面使用是一样的；

private bool UpdateWeahter() { Cursor.Current = Cursors.WaitCursor; try { WebWeather.WeatherWebService objWWS = new WeatherWebService(); string[] strArray = objWWS.getWeatherbyCityName(this.txt<a href="/tag/Box/" target="_blank" class="keywords">Box</a>_City.Text.Trim()); if (strArray.GetLength(0) > 0) { UpdateWeather(strArray); Cursor.Current = Cursors.Default; return true; } Cursor.Current = Cursors.Default; return false; } catch { Cursor.Current = Cursors.Default; return false; } }

 

2、同步系统时间，这个查了好多资料，有一些细节问题需仔细处理

private DateTime SyncTime() { TcpClient client = new TcpClient(); byte[] buffer = new byte[0x40]; string hostname = "time.nist.gov"; int port = 13; string str = ""; Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>.DateTime localtime=DateTime.<a href="/tag/Now/" target="_blank" class="keywords">Now</a>; string[] dates = new string[4]; string[] times = new string[4]; string[] tokens = new string[11]; try { Cursor.Current = Cursors.WaitCursor; client.Connect(hostname,port); client.GetStream().Read(buffer,Convert.ToInt16(0x40)); str = Encoding.ASCII.GetString(buffer,0x40); tokens = str.Split(" ".<a href="/tag/toch/" target="_blank" class="keywords">toch</a><a href="/tag/ara/" target="_blank" class="keywords">ara</a>rray()); dates = tokens[1].Split("-".<a href="/tag/toch/" target="_blank" class="keywords">toch</a><a href="/tag/ara/" target="_blank" class="keywords">ara</a>rray()); times = tokens[2].Split(":".<a href="/tag/toch/" target="_blank" class="keywords">toch</a><a href="/tag/ara/" target="_blank" class="keywords">ara</a>rray()); localtime = new DateTime(Int32.Parse(dates[0]) + 2000,Int32.Parse(dates[1]),Int32.Parse(dates[2]),Int32.Parse(times[0]),Int32.Parse(times[1]),Int32.Parse(times[2])); Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>Time lpSy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>Time = new Sy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>Time(); lpSy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>Time.wYear = Convert.ToUInt16(localtime.Year); lpSy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>Time.wMonth = Convert.ToUInt16(localtime.Month); lpSy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>Time.wDayOfWeek = Convert.ToUInt16(localtime.DayOfWeek); lpSy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>Time.wDay = Convert.ToUInt16(localtime.Day); lpSy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>Time.wHour = Convert.ToUInt16(localtime.Hour); lpSy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>Time.wMinute = Convert.ToUInt16(localtime.Minute); lpSy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>Time.wSecond = Convert.ToUInt16(localtime.Second); lpSy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>Time.wMilliseconds = 0; SetSy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>Time(ref lpSy<a href="/tag/stem/" target="_blank" class="keywords">stem</a>Time); } catch { } finally { client.Close(); Cursor.Current = Cursors.Default; } return TimeZone.CurrentTimeZone.ToLocalTime(localtime); }

 

3、在WINCE里访问注册表，对比一下，看和在Windows里有什么区别

 

private void RegisteQWReg(string City,bool bInit) { RegistryKey localMachine = Registry.LocalMachine; RegistryKey key2 = localMachine.OpenSubKey(@"Software/QuickWeather",true); if (key2 == null) { key2 = localMachine.CreateSubKey(@"Software/QuickWeather"); bInit = true; } if (key2 != null & bInit) { key2.SetValue("u","0"); if (City.Length != 0) { key2.SetValue("City",City); } else { key2.SetValue("City","西安"); } key2.SetValue("uPath",g_sPath + @"/PPCQuickWeather.exe"); key2.SetValue("<a href="/tag/nop/" target="_blank" class="keywords">nop</a>ic",g_sPath + @"/img/<a href="/tag/nothing/" target="_blank" class="keywords">nothing</a>.gif"); key2.SetValue("TQ1",""); key2.SetValue("TQ1D",""); key2.SetValue("TQ1W",""); key2.SetValue("TQ1P1",""); key2.SetValue("TQ1P2",""); key2.SetValue("TQ1H",""); key2.SetValue("TQ1L",""); key2.SetValue("TQ2",""); key2.SetValue("TQ2D",""); key2.SetValue("TQ2W",""); key2.SetValue("TQ2P1",""); key2.SetValue("TQ2P2",""); key2.SetValue("TQ2H",""); key2.SetValue("TQ2L",""); key2.SetValue("TQ3",""); key2.SetValue("TQ3D",""); key2.SetValue("TQ3W",""); key2.SetValue("TQ3P1",""); key2.SetValue("TQ3P2",""); key2.SetValue("TQ3H",""); key2.SetValue("TQ3L",""); key2.SetValue("uLast",""); key2.SetValue("uT1",this.nUD_AM.Value.ToString()); key2.SetValue("uT2",this.nUD_PM.Value.ToString()); } else { this.txt<a href="/tag/Box/" target="_blank" class="keywords">Box</a>_City.Text = key2.GetValue("City","西安").ToString(); this.nUD_AM.Value = Convert.ToDecimal(key2.GetValue("uT1","8").ToString()); this.nUD_PM.Value = Convert.ToDecimal(key2.GetValue("uT2","20").ToString()); } key2.Close(); localMachine.Close(); }

 

4、今日桌面插件的注册，查了好多资料才找到的方法。

{ RegistryKey localMachine = Registry.LocalMachine; RegistryKey key2 = localMachine.OpenSubKey(@"Software/Microsoft/Today/Items/QuickWeather",true); if (key2 == null) { key2 = localMachine.CreateSubKey(@"Software/Microsoft/Today/Items/QuickWeather"); } key2.SetValue("DLL","QuickWeather.dll"); key2.SetValue("Enabled",1); key2.SetValue("Flags",0); key2.SetValue("Options",0); key2.SetValue("Order",0); key2.SetValue("Selectability",1); key2.SetValue("<a href="/tag/stem/" target="_blank" class="keywords">stem</a><a href="/tag/bed/" target="_blank" class="keywords">bed</a>ded",""); key2.SetValue("Type",4); key2.SetValue("启用",1); key2.SetValue("顺序",8); key2.Close(); localMachine.Close(); Message<a href="/tag/Box/" target="_blank" class="keywords">Box</a>.Show("今日<a href="/tag/chajian/" target="_blank" class="keywords">插件</a>已经安装完成！"); PostMessage(HWND_<a href="/tag/bro/" target="_blank" class="keywords">bro</a>ADCAST,WM_SETTINGCHANGE,(IntPtr)0xF2,(IntPtr)0); }

 

5、今日插件的开发。

今日插件是一个比较特殊的软件，必须是dll方式，而且必须符合一定的要求，这方面的资料比较少，很难一句两句说清楚，后面有时间将另文说明。

 

 

总结，这是第一次用.net开发WM下的软件，感觉和Windows下大体上差不多，但又有区别，以前对这方面关注较少，一些小问题花费了很多的时间。
