1、升级
下载水晶报表10。安装时选择.NET组件。如果VS2003已经安装好会自动将其内置水晶报表升级为10

2、使用
拖一个CrystalReportViewer到Form上
添加新项目，选择水晶报表。安装向导连接数据库选择表即可建成rpt文件。
添加如下代码：
  private void Page_Load(object sender, System.EventArgs e)
  {
            initDataSet();

   //Create an instance of the strongly-typed report object
   LotTrackCross crReportDocument = new LotTrackCross();

   //Pass the populated dataset to the report
   crReportDocument.SetDataSource(dataSet);

   //Set the viewer to the report object to be previewed.
   CrystalReportViewer1.ReportSource = crReportDocument;
  }
  private void initDataSet()
  {
   string querySql ="select * from tblLotTrack where lot< 535120 and stn < 5000 ";              
    OleDbConnection cn = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source= c:\LTS2005.mdb");
   cn.Open();                                                           
   OleDbDataAdapter adapter = new OleDbDataAdapter(querySql,cn);         
   adapter.SelectCommand = new OleDbCommand(querySql, cn);              
   adapter.Fill(dataSet);                                                
  }
注意：填充使用的DataSet要和建立rpt文件的表名、列名对应
