Process- select bill no->click on print button->show the particular bill of given bill no.) what code can I write to display this bill properly?

推荐答案

你可以尝试这样的c＃按钮代码但是我不要以为c＃和vb代码之间会有这么大的区别。



//首先添加命名空间

u can try like that this is c# button code but i do not think there would be so much difference between c# and vb code .

// firstly add namespace

using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.ReportSource;
using CrystalDecisions.Shared;

protected void btnPrint_Click(object sender, EventArgs e)
    {
        ReportDocument rptDoc = new ReportDocument();
        rptDoc.Load(Server.MapPath("../RPT/crstSubReport.rpt"));
        CrystalDecisions.Shared.TableLogOnInfo loginfo;

        foreach (CrystalDecisions.CrystalReports.Engine.Table myTable in rptDoc.Database.Tables)
        {
            loginfo = myTable.LogOnInfo;
            loginfo.ConnectionInfo.ServerName = @"";
            loginfo.ConnectionInfo.DatabaseName = "";
            loginfo.ConnectionInfo.UserID = "";
            loginfo.ConnectionInfo.Password = "";


            myTable.ApplyLogOnInfo(loginfo);

        }
 MemoryStream stream = (MemoryStream)rptDoc.ExportToStream(ExportFormatType.PortableDocFormat);
        Response.Clear();
        Response.Buffer = true;
        Response.ContentType = "application/pdf";
        Response.BinaryWrite(stream.ToArray());
        rptDoc.Refresh();
}
