水晶报表项目运行时 去掉 输入连接数据库密码 的页面

阅读全文：并下载例子：http://www.cckan.net/forum.php?mod=viewthread&tid=175

1.把连接数据库的代码写在web.config文件中

    在 <connectionStrings> </connectionStrings>中加入以下代码：

    <add name="Data Source" connectionString="***.***.***.***" />
     <add name="Initial Catalog" connectionString="******" />
     <add name="User ID" connectionString="******" />
     <add name="Password" connectionString="******" />

 

2.具体代码：

    public class  CrystalHelper
    {
        public void NoPasswd(CrystalReportViewer crystalReportViewer, string  path1)
        {
            TableLogOnInfo logOnInfo = new  TableLogOnInfo();
            //这里必须事先申明一个ReportDocument对象 Report，同时加载数据报表
            ReportDocument oRpt = new  ReportDocument();
            // 获取.rpt文件真实路径
            //path1 = Microsoft.SqlServer.Server.MapPath("~/Pages/ARC/ARCjp.rpt");

            oRpt.Load(path1);

             //从web.config中获取logOnInfo参数信息
            string  a, b, c, d;
            //获取ServerName
            a = ConfigurationManager.ConnectionStrings["Data Source" ].ConnectionString;
            //获取DatabaseName
            b = ConfigurationManager.ConnectionStrings["Initial Catalog" ].ConnectionString;
            //获取UserId
            c = ConfigurationManager.ConnectionStrings["User ID" ].ConnectionString;
            //获取password
            d = ConfigurationManager.ConnectionStrings["Password" ].ConnectionString;
            //设置logOnInfo参数

            logOnInfo.ConnectionInfo.ServerName  =  a;
            logOnInfo.ConnectionInfo.DatabaseName =  b;
            logOnInfo.ConnectionInfo.UserID =  c;
            logOnInfo.ConnectionInfo.Password =  d;

            oRpt.Database.Tables[0 ].ApplyLogOnInfo(logOnInfo);

            //建立.rpt文件与CryStalReportviewer文件之间的连接
            crystalReportViewer.ReportSource =  oRpt;
        }
    }

 

3.在调用水晶报表文件的页面的***.cs页面中调用2中的方法：

            CrystalHelper cry = new  CrystalHelper();
            cry.NoPasswd(CrystalReportViewer1, Server.MapPath("~/Pages/Arc/ArcJp.rpt" ));
