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

namespace App
{
    public partial class frmPreviewRpt : Form
    {
        private ReportClass m_rpt = new ReportClass();
        public frmPreviewRpt(ReportClass rpt, DataTable dt)
        {
            InitializeComponent();
            m_rpt = rpt;

            if (dt != null)
                m_rpt.SetDataSource(dt);

            this.Name = rpt.ResourceName;
        }

        private void frmPreviewRpt_Shown(object sender, EventArgs e)
        {
            this.WindowState = FormWindowState.Maximized;
        }

        private void frmPreviewRpt_Load(object sender, EventArgs e)
        {
            crystalReportViewer1.DisplayGroupTree = false;
            crystalReportViewer1.ReportSource = m_rpt;
        }
    }
}

            int year = 2013;
            int month = 5;
            RPT_Name myRpt = new RPT_Name();
            DataTable dt = getDataTable();

            //傳遞報表DataTable資料
            myRpt.SetDataSource(dt);

            //若報表有定義參數，用以下方式給值
            myRpt.SetParameterValue("myyear", year.ToString());
            myRpt.SetParameterValue("mymonth", month.ToString());

            frmPreviewRpt frm = new frmPreviewRpt(myRpt, null);
            frm.MdiParent = (frmMain)this.Parent.Parent;
            frm.Text = this.Text + "預覽";
            frm.Show();
