两种视图的同步
在 3bxwMap.cs 中添加成员变量，即同步类对象：
private ControlsSynchronizer m_controlsSynchronizer = null;
在 Form1_Load 函数中进行初始化工作：
controls synchronization calss
m_controlsSynchronizer = new ControlsSynchronizer(m_mapControl, m_pageLayoutControl);
m_controlsSynchronizer.BindControls(true);
m_controlsSynchronizer.AddFrameworkControl(axToolbarControl1.Object); m_controlsSynchronizer.AddFrameworkControl(this.axTOCControl1.Object); OpenNewMapDocument openMapDoc = new
OpenNewMapDocument(m_controlsSynchronizer);
axToolbarControl1.AddItem(openMapDoc, -1, 0, false, -1, esriCommandStyles.esriCommandStyleIconOnly);

打印功能
o. 添加打印菜单项。双击菜单项添加响应函数：
IHookHelper layout_hookHelper = new HookHelperClass(); layout_hookHelper.Hook = this.axPageLayoutControl1.Object; PrintPageLayoutForm PPLFrm =newPrintPageLayoutForm(layout_hookHelper); PPLFrm.ShowDialog();
新建Windows窗体：
代码如下： using System;
using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing;
using System.Text;
using System.Windows.Forms; using ESRI.ArcGIS.Output; using ESRI.ArcGIS.Controls; using ESRI.ArcGIS.Carto; namespace GIS {
public partial class PrintPageLayoutForm : Form {
public PrintPageLayoutForm(IHookHelper hookHelper) {
InitializeComponent();
axPageLayoutControl1.PageLayout = hookHelper.PageLayout; }
private void cmdPrint_Click(object sender, System.EventArgs e) {
if (axPageLayoutControl1.Printer != null) {
axPageLayoutControl1.MousePointer =
esriControlsMousePointer.esriPointerHourglass; IPrinter printer = axPageLayoutControl1.Printer; if (printer.Paper.Orientation !=axPageLayoutControl1.Page.Orientation) {
printer.Paper.Orientation = axPageLayoutControl1.Page.Orientation; UpdatePrintingDisplay(); }
axPageLayoutControl1.PrintPageLayout(Convert.ToInt16(txbStartPage.Tex
