Question

这是登录信息方法

private void SetLogonInfo()
    {
        try
        {
            LogInfo.ConnectionInfo.ServerName = "ServerName";
            LogInfo.ConnectionInfo.UserID = "UserID";
            LogInfo.ConnectionInfo.Password = "Password";
            LogInfo.ConnectionInfo.DatabaseName = "DataBase";
        }

        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }

    }

要创建报告，我使用了此代码

            crystalReportViewer1.ReportSource = null;
            rptdoc = new ReportDocument();
            rptdoc.Load("REPORTS\\TC.rpt");
            crystalReportViewer1.SelectionFormula =selectionFormula;
            crystalReportViewer1.ReportSource = rptdoc;
            rptdoc.Database.Tables[0].ApplyLogOnInfo(LogInfo);

它在服务器系统中运行良好，但如果我在客户端系统中使用它，它会要求输入用户名和密码。我正在使用Crystal Reports 10.此外，有时它还要求在服务器系统中输入用户名密码。如何解决这个问题？

Answer 1

你正在以错误的顺序做事。您需要以编程方式登录，然后才能在查看器上加载报告。

此外，在向用户发布之前，我不能强调您需要在服务器计算机和测试客户端计算机上测试您的程序。

Answer 2

出现此错误的原因是用户名，密码错误检查用户名，密码并使用以下代码：

ReportDocument cryRpt = new ReportDocument();
TableLogOnInfos crtableLogoninfos = new TableLogOnInfos();
TableLogOnInfo crtableLogoninfo = new TableLogOnInfo();
ConnectionInfo crConnectionInfo = new ConnectionInfo();
Tables CrTables;

//This is for Access Database
crConnectionInfo.ServerName = "" + "" +Application.StartupPath + "\\Database.mdb"; //access Db Path
crConnectionInfo.DatabaseName = "" + "" + Application.StartupPath + "\\Database.mdb";//access Db Path
crConnectionInfo.UserID = "ADMIN";
crConnectionInfo.Password = Program.DBPassword; //access password

//This is for Sql Server
crConnectionInfo.UserID = Program.Severuser; //username
crConnectionInfo.Password = Program.Password;//password
crConnectionInfo.ServerName = Program.server;//servername
crConnectionInfo.DatabaseName = Program.database;//database

string path = "" + Application.StartupPath + "\\supportingfiles\\Invoice.rpt";
cryRpt.Load(path);
CrTables = cryRpt.Database.Tables;
foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in CrTables)
{
   crtableLogoninfo = CrTable.LogOnInfo;
   crtableLogoninfo.ConnectionInfo = crConnectionInfo;
   CrTable.ApplyLogOnInfo(crtableLogoninfo);
}

cryRpt.SetParameterValue("invoiceno", Program.billno);

crystalReportViewer1.ReportSource = cryRpt;
crystalReportViewer1.Refresh();

Crystal Reports在客户端系统中询问密码
