有关CrystalReport打印的页面设置

[dean615]

掉用水晶报表时，如果直接调用它的打印函数，页面类型会不是规定的A4类型，如过让报表页面显示出来，然后手动点击打印按钮
页面设置就是规定的A4类型，请问，如何在不显示报表页面的情况下，直接调用他的打印功能，还能让他的页面类型是A4
CrystalReportVIPMale crystalVIP = new CrystalReportVIPMale();
crystalVIP.PrintOptions.PaperSize = PaperSize.PaperA4;
this.CrystalReportViewer1.ReportSource = crystalVIP;
//this.CrystalReportViewer1.PrintReport();这个是直接调用打印功能的方法

这样看看，指定打印机名称的。

CrystalReportVIPMale crystalVIP = new CrystalReportVIPMale();
crystalVIP.PrintOptions.PrinterName = "打印机名称";
crystalVIP.PrintOptions.PaperSize = PaperSize.PaperA4;
crystalVIP.PrintToPrinter(1, False, 1, 99);

不行呢，到 crystalVIP.PrintToPrinter(1, false, 1, 99)时就会报错：
System.Collections.ListDictionaryInternal
System.Runtime.InteropServices.COMException (0x8004100F):
文件 C:\DOCUME~1\Dean.Xu\LOCALS~1\Temp\temp_af6cc12f-98d5-4785-a846-e2296e9414a6 {A8A7D7A9-B3FF-41C9-8A3D-B010BAFC4490}.rpt 内出错：

你直接在报表里设为A4不行吗？右击设计报表里可以设的。

[dean615]

不行，我试了，直接调用打印方法时，设置的属性全没了。
不知道为什么

下面是帮助文档里的数据库登录实例。将登录信息赋给报表对象。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;

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

        private void ConfigureCrystalReports()
        {
            ConnectionInfo connectionInfo = new ConnectionInfo();
            connectionInfo.ServerName = "dholmes_50701";
            connectionInfo.DatabaseName = "Northwind";
            connectionInfo.UserID = "limitedPermissionAccount";
            connectionInfo.Password = "1234";
            string reportPath = Application.StartupPath + "\\" + "NorthwindCustomers.rpt";
            crystalReportViewer.ReportSource = reportPath;
            SetDBLogonForReport(connectionInfo);
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            ConfigureCrystalReports();
        }

        private void crystalReportViewer_Load(object sender, EventArgs e)
        {

        }

        private void SetDBLogonForReport(ConnectionInfo connectionInfo)
        {
            TableLogOnInfos tableLogOnInfos = crystalReportViewer.LogOnInfo;
            foreach (TableLogOnInfo tableLogOnInfo in tableLogOnInfos)
            {
                tableLogOnInfo.ConnectionInfo = connectionInfo;

            }

        }
    }
}

然后再写个单独的打印事件看看

好的，我去试下，谢谢

[dean615]

private void ConfigureCrystalReports()
{
ConnectionInfo connectionInfo = new ConnectionInfo();
connectionInfo.ServerName = "DEV.NMH.BHG.COM";
connectionInfo.DatabaseName = "";
connectionInfo.UserID = "PHYSICAL";
connectionInfo.Password = "EXAM";
string reportPath = Application.StartupPath + "\\" + "CrystalReportVIPMale.rpt";
this.CrystalReportViewer1.ReportSource = reportPath;
//this.CrystalReportViewer1.LogOnInfo.Add(logInfo);
TableLogOnInfos tableLogOnInfos = this.CrystalReportViewer1.LogOnInfo;
foreach (TableLogOnInfo tableLogOnInfo in tableLogOnInfos)
{
tableLogOnInfo.ConnectionInfo = connectionInfo;

}
}
private Test()
{
ConfigureCrystalReports(logInfo);
CrystalReportVIPMale crystalVIP = new CrystalReportVIPMale();
crystalVIP.PrintOptions.PrinterName = "Microsoft Office Document Image Writer";
crystalVIP.PrintOptions.PaperSize = PaperSize.PaperA4;
crystalVIP.PrintToPrinter(1, false, 1, 99);
}
可以运行到crystalVIP.PrintToPrinter(1, false, 1, 99);然后报如下错：
System.Collections.ListDictionaryInternal
System.Runtime.InteropServices.COMException (0x8004100F):
文件 C:\DOCUME~1\Dean.Xu\LOCALS~1\Temp\temp_5cb9f206-67e2-453d-a7e2-31a560894eb2 {46A936D9-4EDC-4869-8DC9-DCE77BA44EB5}.rpt 内出错：
无法连接：错误的登录参数。

[阿泰]

connectionInfo.DatabaseName = "";

这个参数怎么会为空？

[dean615]

我现在加上那个参数了，会报同样的错，我的数据库是ORACLE的，跟数据库没关系吧

路过，顶一下，以表支持

[dean615]

解决，要给.rpt文件附上数据源，偷懒，直接用DATASET老做了。
谢谢
