This article describes a program that develops a weather forecast service on a smartphone based on the SmartPhone operating system. [Introduction]
We all know that QQ has a free offer to blog quoted weather forecast service URL http://appnews.qq.com/cgi-bin/news_qq_search?city= Shanghai (Shanghai is my own city, if you want to see your city, Change to the city name in the browser), now I use this service provided by QQ, deploy it into a web service, and write programs to make my Dopod 565 smartphone can use this web service.

PC Development Environment: Windows XP SP2, Visual Studio 2003.net, .NET Framework 1.1 SP1
Operating System: Windows Mobile (TM) 2003 Second Edition, Version 4.21.1088 (Build 14235.2.0.0)
Smartphone model: Dopod 565
First, install the necessary environment
Note: The development environment you need to install .NET Mobile
The software that must be installed (the following software is Microsoft to provide free download and use) 1, Microsoft ActiveSync 3.7.1 (the latest version Microsoft ActiveSync 3.8 out, you can go to the summary page to find the link download, this I haven't tried it yet Download URL: http://www.microsoft.com/WindowsMobile/downloads/activeSync37.mspx, there is a Chinese version, or have an installer in Microsoft CDs that came with your phone; role: Synchronize your phone and PC data program
2, Microsoft SMARTPHONE 2003 SDK.msi download URL: http: //download.microsoft.com/download/e/3/1/e310bb99-2f33-4d79-bb8a-41d9cb3c79b4/Microsoft SMARTPHONE 2003 SDK.msi 3, MobileAppDevToolkit2004.exe Download address: http://download.microsoft.com/download/b/2/5/b25742c0-daa3-4a8c-988d-a947a35e68/mobileappdevtoolkit2004.exe 2, deploy QQ service into WebService
1. Build a WeatherService WebService and turn the QQ weather service to the XML WebService service, and deploy on a server with fixed IP.
2, create a new weatherdataset.xsd, store our weather information

Figure 5, one of the mobile interface - deployment Because I installed .NET Framework1.1sp1 on my PC machine, I will prompt this interface, select "OK", continue to perform the installation deployment: Figure 6. Two of the mobile interface - Select the installation location Select the installation location to "SOTRAGE CARD", select Finish, this time the program is deployed, Using Resco Explore 2003, find the directory where the program is installed, in the / Sorage / Program Files / WeatherService / Directory, execute the program weatherService.exe, will appear as follows: Figure 7, the three mobile interface - start executing the program Select "Yes", this picture, because the program does not have systematic authentication, and it is also an embodiment of Microsoft security. Instant this program will be implemented normally, and it will not take a call! After the program execution, the following screen will appear, select the name of the city you need to query, click "OK" Figure 8, the four-program interface of the mobile phone interface The program title will change to "download ...", the program reads the WEBSERVICE deployed on the Internet via GPRS.
