Question

我正在使用Windows 7，SQL Server 2000和VS 2008 / Crystal Report XI。

点击GetReport按钮后，我收到了以下错误。

登录失败。详细信息：ADO错误代码：0x源：用于SQL Server的Microsoft OLE DB提供程序说明：用户“sa”的登录失败。 SQL状态：42000本机错误：文件C中的错误：\ Users \ bahadur \ AppData \ Local \ Temp \ Total_Sales_Comparision {C4649F80-D1F7-4AED-A4B1-0B8EF83996C6} .rpt：无法连接：登录参数不正确。块引用

我的C＃代码低于

ConnectionInfo crConnectionInfo = new ConnectionInfo();
crConnectionInfo.ServerName = "BRAVEALI-PC";
crConnectionInfo.DatabaseName = "SCM_TEST";
crConnectionInfo.UserID = "sa";
crConnectionInfo.Password = "myDB Password";

ReportDocument report = new ReportDocument();
report.Load(@"D:\Project's\SCM Reports\Total_Sales_Comparision.rpt");
report.SetParameterValue("@invcm_date_from", Convert.ToDateTime (TextBox4.Text));
report.SetParameterValue("@invcm_date_to", Convert .ToDateTime(TextBox5.Text));
CrystalReportViewer1.ReportSource = report;
//CrystalReportViewer1.RefreshReport();

此致

Answer 1

你从未对你的crConnectionInfo对象做过任何事情......你没有把它绑回到你的报告对象上。

它为您提供了错误的登录信息，因为您从未设置过登录信息。

Answer 2

使用此代码设置登录信息，

        TableLogOnInfos crtableLogoninfos = new TableLogOnInfos();
        TableLogOnInfo crtableLogoninfo = new TableLogOnInfo();
        ConnectionInfo crConnectionInfo = new ConnectionInfo();
        Tables CrTables;
        crConnectionInfo.ServerName = "Servername";
        crConnectionInfo.DatabaseName = "Database";
        crConnectionInfo.UserID = "Userid";
        crConnectionInfo.Password = "password";

        CrTables = cryRpt.Database.Tables;
        foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in CrTables)
        {
            crtableLogoninfo = CrTable.LogOnInfo;
            crtableLogoninfo.ConnectionInfo = crConnectionInfo;
            CrTable.ApplyLogOnInfo(crtableLogoninfo);
        }

或只是使用

      yourreport.setdatabaselogon("username","Password","servername","databasename");
