水晶报表 +登陆失败＋操作办法

想要在.aspx文件中使用水晶报表
1.先新建文件webform1.aspx 在页面拖入组件CrystalReportViewer 生成代码oRpt.Load(RptDir);

//设置logOnInfo参数，注意这里如果不设?编译时最容易出现“登陆失败”的错误！
logOnInfo.ConnectionInfo.ServerName = "服务器名";
logOnInfo.ConnectionInfo.DatabaseName = "数据库名";
logOnInfo.ConnectionInfo.UserID = "用户名";
logOnInfo.ConnectionInfo.Password = "密码";
oRpt.Database.Tables [0].ApplyLogOnInfo(logOnInfo);

//建立.rpt文件与CryStalReportviewer文件之间的连接
CrystalReportViewer1.ReportSource=oRpt;
}

4.//生成pdf文档 在以上代码中加入
 ExportOptions crExportOptions=new ExportOptions();
DiskFileDestinationOptions crDiskFileDestinationOptions=new DiskFileDestinationOptions();
crDiskFileDestinationOptions.DiskFileName="f:\\bbs\\test\\crystal\\crystalreport1.pdf";
crExportOptions=oRpt.ExportOptions ;
crExportOptions.DestinationOptions=crDiskFileDestinationOptions;
crExportOptions.ExportDestinationType =ExportDestinationType.DiskFile;
crExportOptions.ExportFormatType =ExportFormatType.PortableDocFormat ;

oRpt.Export();
oRpt.Close();

5.//读取报表导出的内容并传到客户端?继续加入以下代码
Response.ClearContent();
Response.ClearHeaders ();
Response.ContentType ="application/pdf";
Response.WriteFile("f:\\bbs\\test\\crystal\\crystalreport1.pdf");

Response.Flush();
Response.Close();?
