Crystal報表需要登錄

Question

我寫在Visual Studio 2010中的以下內容：

label2.Text = Convert.ToString(BAssistencia.nroo); 
    ReportDocument oRep = new ReportDocument(); 
    ParameterField campo = new ParameterField(); 
    ParameterFields campo2 = new ParameterFields(); 
    ParameterDiscreteValue Pdv = new ParameterDiscreteValue(); 

    campo.Name = "@pedido"; 
    Pdv.Value = label2.Text; 
    campo.CurrentValues.Add(Pdv); 
    campo2.Add(campo); 
    crystalReportViewer1.ParameterFieldInfo = campo2; 
    oRep.Load("C:/Relatorios/CrystalReport3.rpt"); 
    crystalReportViewer1.ReportSource = oRep; 
    oRep.SetDatabaseLogon("sa","password","server","database"); 

報告打開計算機與Visual Studio的罰款，但是當我部署，應用程序再次請求日誌然後再次。我究竟做錯了什麼？提前致謝。

Answer 1

你可以試試這個代碼

ReportDocument rpt = new ReportDocument(); 
     rpt.Load(@"C:\CrystalReport1.rpt"); 

     ConnectionInfo crConnectionInfo = new ConnectionInfo(); 
     crConnectionInfo.ServerName = "SERVERNAME"; 
     crConnectionInfo.DatabaseName = "DATABASENAME"; 
     crConnectionInfo.UserID = "USERNAME"; 
     crConnectionInfo.Password = "PASSWORD"; 
     crConnectionInfo.IntegratedSecurity = false; 

     TableLogOnInfos crTableLogonInfos = new TableLogOnInfos(); 
     TableLogOnInfo crTableLogonInfo = new TableLogOnInfo(); 
     Tables CrTables; 
     CrTables = rpt.Database.Tables; 

     foreach (CrystalDecisions.CrystalReports.Engine.Table crTable in CrTables) 
     { 
      crTableLogonInfo = crTable.LogOnInfo; 
      crTableLogonInfo.ConnectionInfo = crConnectionInfo; 
      crTable.ApplyLogOnInfo(crTableLogonInfo); 
     } 
     crystalReportViewer1.ReportSource = rpt; 
     crystalReportViewer1.Refresh();

你有解決這個問題的兩種選擇。

1. 使用Windows用戶帳戶數據庫訪問 More details are here

2. 應用憑據主報告和動態的所有子報表
