刷新報告時登錄失敗

我有一個應用程序與MsAcess數據庫。在它的一種形式中，我使用Crystal報表查看器來顯示一個水晶報表，但問題是在加載它的空白報告後，如果我嘗試刷新其給出錯誤 enter image description here 刷新報告時登錄失敗

我的代碼報告如下

private void button1_Click(object sender, EventArgs e) 
     { 
      try 
      { 
       crystalReportViewer1.ReportSource = getpeport(@"C:\shrinkage\New folder\Shrinkage details1-bysreenath.rpt"); 



       crystalReportViewer1.SelectionFormula = "{CONS_MAST.CONSID} = '" + cmb_cons.Text + "' and {CONSUMPTION.STYLE} = '" + cmb_style.Text + "' and {CONSUMPTION.BUYER} = '" + cmb_buyer.Text + "'"; 
      //crystalReportViewer1.RefreshReport(); 
      } 
      catch (Exception exp) 
      { 

       MessageBox.Show(exp.ToString()); 
      } 
      finally 
      { 
       oleDbConnection1.Close(); 
      } 
      // crystalReportViewer1.RefreshReport(); 
     }   



     public ReportDocument getpeport(String ReportLocation) 
     { 
      ConnectionInfo crconnectioninfo = new ConnectionInfo(); 
      ReportDocument cryrpt = new ReportDocument(); 
      TableLogOnInfos crtablelogoninfos = new TableLogOnInfos(); 
      TableLogOnInfo crtablelogoninfo = new TableLogOnInfo(); 

      Tables CrTables; 



      crconnectioninfo.ServerName = @"C:\shrinkage\Shrinkage.mdb"; 
      crconnectioninfo.DatabaseName = ""; 
     crconnectioninfo.UserID = ""; 
    crconnectioninfo.Password = ""; 

      cryrpt.Load(ReportLocation); 

      CrTables = cryrpt.Database.Tables; 

      foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in CrTables) 
      { 
       crtablelogoninfo = CrTable.LogOnInfo; 
       crtablelogoninfo.ConnectionInfo = crconnectioninfo; 
       CrTable.ApplyLogOnInfo(crtablelogoninfo); 
      } 
      // cryrpt.Refresh(); 
      return cryrpt; 
     }

本報告分別以水晶報告第十一設計，有我能夠做到的刷新和查看數據also.Pls幫我建議

嘗試添加「oleDBConnection1.Open（）;」到button1_Click方法的開始。你最後關閉連接，但是你永遠不會打開它。
