Question

我使用Visual Studio 2008来开发应用程序。我使用Microsoft OLE DB Provider for SQL Server，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(); 
        }
    }
}
