实例讲解PDA入门开发的过程，附代码

实例讲解PDA入门开发的过程，附代码本程序为PDA 入门开发的一个小示例,希望对大家有所帮助，基于mobile5.0的PPC开发,使用语言C#，我的机器的环境：windows 2003(E),SQL2005(E),VS2005(E)--------------------------首先安装环境---------------------一个模拟器，和链接PDA的工具1 Microsoft ActiveSync 4.2.exe --PDA中使用的数据库2 sqlce30setupen.msi—版本ce3.0,cf2.0 SSCE31SDK-CHS1.msi--PPC开发工具的SDK3 Windows Mobile 5.0 Pocket PC SDK2.msi--3的汉化4 Windows Mobile 5.0 Emulator Images for Pocket PC - CHS3.msi--pda中安装的数据库sqlce,安装文件必须是cab的，否则不能识别5 sqlce30.ppc.wce4.armv4.CAB --路径：C:/Program Files/Microsoft SQL Server Compact Edition/v3.1/SDK/bin/Client/v2.0/wce500/armv4i--------------------------------配置开发环境-----------------------1 Tools->Device Emulaor Manager(1)默认选择：Pocket Pc 2003 SE Emulaor 右键->connection之后cradle(2)安装mobile5.0后选择：CHS Windows Mobile5.0 Pocket Pc Emulaor 右键->connection之后cradle2 弹出Synchronization Setup Wizard 一直next 将链接上模拟的PDA -----------------------------创建winform项目----------------------File -> new ->project->Visual c#->Smart Device->PPc2003->Device Application--------------------------小测试----------------------（1）放一个button就可以在PDA中看见效果了（2）如果是Web的测试程序，在PDA的IE中输入 https://192.168.0.114/localhost/website/defualt.aspx ----------------------------数据库的配置与基本使用-----------------------SQL Server Mobile 学习:--通过VS2005 创建和连接及操作SQL Server Mobile 数据库a. 在项目外创建SQL Server Mobile数据库b. 在项目内创建SQL Server Mobile数据库c. 连接SQL Server Mobile数据库d. 操作SQL Server Mobile数据库=============================＝＝＝ a. 在项目外创建数据库----------------------(1).在“视图”菜单上单击“服务器资源管理器”。(2).右击“数据连接”，然后单击“添加连接”，打开“添加连接”对话框。(3).单击“更改”，打开“更改数据源”对话框。(4).在“数据源”框中，选择“Microsoft SQL Server Mobile Edition”，然后单击“确定”。(5).选择“Microsoft SQL Server Mobile Edition”，然后单击“确定”。 b.在项目内创建数据库---------------------(1).打开一个项目后，在“数据”菜单上单击“添加新数据源”。将打开“数据源配置向导”。(2).在“选择数据源类型”页上，选择“数据库”，然后单击“下一步”。(3).在“选择您的数据连接”页上单击“新建连接”，打开“添加连接”对话框。(4).单击“更改”，打开“更改数据源”对话框。(5).选择“Microsoft SQL Server Mobile Edition”，然后单击“确定”。 c.连接数据库-------------以下步骤呈接上面的a或b (1).在“添加连接”对话框中，选择“我的电脑”。(2).单击“创建”。(3).在“创建新的SQL Server 2005 Mobile Edition 数据库”对话框中，键入新数据库的完全限定路径，如“c:/MyDB”。(4).在“新密码”和“确认密码”框中键入新数据库的密码（如“MyPassword”），然后单击“确定”。(5).在“添加连接”对话框中，单击“测试连接”以确保已建立连接。出现一条消息指示测试连接成功。注意SQL Server Mobile 不支持在网络共享上打开数据库文件。(6).单击“确定”，返回到“添加连接”对话框，然后单击“确定”关闭该对话框。(7).在“选择您的数据连接”页上，选择“是，在连接字符串中包含敏感数据”。(8).单击“下一步”。出现“本地数据库文件”消息框，询问是否要在当前项目中包括数据文件。单击“是”。(9).在“选择您的数据库对象”页上，选择要在项目中包含的表或其他对象。(10).单击“完成”。 d. 操作SQL Server Mobile数据库-------------------------这时通过在“数据”菜单上单击“显示数据源”，可以在“数据源”窗口中将新数据库作为数据集进行查看。后续的操作可以通过单击某项的右键来进行 ----------------------程序代码-------------------- 前台：一个dataGrid，一个button，一个Text后台如下：
