使用Microsoft OLE DB Provider for SQL Server的CRYSTAL REPORT

Question

我正在使用Visual Studio 2008开发应用程序。我为SQL Server使用Microsoft OLE DB提供程序，但在报告显示之前，请求用户名和密码。 我想知道如何绕过用户名和密码？

Answer 1

如果您通过代码传递服务器详细信息和登录凭据，则不应提示用户。

例如：

using System; 
using System.Windows.Forms; 
using CrystalDecisions.CrystalReports.Engine; 
using CrystalDecisions.Shared; 

namespace WindowsApplication1 
{ 
    public partial class Form1 : Form 
    { 
     public Form1() 
     { 
      InitializeComponent(); 
     } 

     private void button1_Click(object sender, EventArgs e) 
     { 
      ReportDocument cryRpt = new ReportDocument(); 
      TableLogOnInfos crtableLogoninfos = new TableLogOnInfos(); 
      TableLogOnInfo crtableLogoninfo = new TableLogOnInfo(); 
      ConnectionInfo crConnectionInfo = new ConnectionInfo(); 
      Tables CrTables ; 

      cryRpt.Load("PUT CRYSTAL REPORT PATH HERE\CrystalReport1.rpt"); 

      crConnectionInfo.ServerName = "YOUR SERVER NAME"; 
      crConnectionInfo.DatabaseName = "YOUR DATABASE NAME"; 
      crConnectionInfo.UserID = "YOUR DATABASE USERNAME"; 
      crConnectionInfo.Password = "YOUR DATABASE PASSWORD"; 

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

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