2. 创建WPF应用程序
环境: VS2008 SP1+ArcEngine
创建一个WPF应用程序命名为WPFMapViewer,至于如何创建,这里就不多累赘了.
3.添加必要的引用
ESRI.ArcGIS.AxControls—包含了 AxMapControl
ESRI.ArcGIS.System—包含了 AoInitialiseClass类 (用于初始化 ArcGIS Engine 的许可)
WindowsFormsIntegration—包含了WindowsFormsHost 控件
System.Windows.Forms
System.Drawing
4.将WindowsFormsHost 从工具箱中拖放到窗体上,并打开MapWindow.xaml,添加WindowsFormsHost 的命名空间
xmlns:i="clr-namespace:System.Windows.Forms.Integration;assembly=WindowsFormsIntegration"
5.为控件创建WindowsFormsHost . 由于一个WindowsFormsHost 只能承载一个window form的控件,因此我们需要为每一个我们用到的AE控件创建一个WindowsFormsHost .这里我们将会用到AxMapControl,AxToolbarControl,AxTOCControl.因此创建三个WindowsFormsHost 控件,分别命名为mapHost,toolbarHost,tocHost.
<i:WindowsFormsHost Height="32" Name="toolbarHost" VerticalAlignment="Top" />
<i:WindowsFormsHost HorizontalAlignment="Left" Margin="0,29,0,25"Name="tocHost" Width="166" />
<i:WindowsFormsHost Margin="167,29,0,25" Name="mapHost" />
6.经过以上的步骤后,完整的xaml应该是这样:
MapWindow.xaml
<Window x:Class="WPFMapViewer.MapWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MapViewer Hosted in WPF" Height="433.29" Width="559.944" Loaded="Window_Loaded" Background="Beige"
MaxHeight="600" MaxWidth="840"
xmlns:i="clr-namespace:System.Windows.Forms.Integration;assembly=WindowsFormsIntegration">
<Grid>
<i:WindowsFormsHost Name="mapHost" Margin="174,30,0,22" />
<i:WindowsFormsHost Margin="0,30,0,22" Name="tocHost" HorizontalAlignment="Left" Width="173" />
<i:WindowsFormsHost Height="30" Name="toolbarHost" VerticalAlignment="Top" />
<TextBlock Height="23.75" VerticalAlignment="Bottom" Name="textBlock1" Margin="0,0,7.056,0">Ready</TextBlock>
</Grid>
</Window>
7.打开App.XAML.cs 文件,在里面添加AE的许可验证代码
App
public App ()
{
InitializeEngineLicense ();
}
private void InitializeEngineLicense ()
{
AoInitialize aoi = new AoInitializeClass ();
//more license choices could be included here
esriLicenseProctCode proctCode = esriLicenseProctCode.esriLicenseProctCodeEngine;
if (aoi.IsProctCodeAvailable (proctCode) == esriLicenseStatus.esriLicenseAvailable)
{
aoi.Initialize (proctCode);
}
}
8. 打开MapWindow.xaml.cs, 在这里编写本文的核心部分.
(1).引入命名空间
using ESRI.ArcGIS.esriSystem;
using ESRI.ArcGIS.Controls;
(2).声明私有变量,包含三个控件:AxMapControl,AxToolbarControl,AxTOCControl
AxMapControl mapControl;
AxToolbarControl toolbarControl;
AxTOCControl tocControl;
(3).创建一个用于初始化创建AE控件的函数,
CreateEngineControls
/// <summary>
/// 创建Engine控件并将控件绑定到各自的 WindowsFormsHost 元素上
/// </summary>
void CreateEngineControls ()
{
//设置 Engine 控件到每个host的Child属性上
mapControl = new AxMapControl ();
mapHost.Child = mapControl;
toolbarControl = new AxToolbarControl ();
toolbarHost.Child = toolbarControl;
tocControl = new AxTOCControl ();
tocHost.Child = tocControl;
}
(4).此外,还需设置一些基本的属性,比如toolbarControl或tocControl必须和mapcontrol进行绑定;添加命令按钮到toolbarControl上;挂接mapControl相关事件等等
SetControlsProperty
/// <summary>
/// 设置控件相关的属性
/// </summary>
private void SetControlsProperty ()
{
//设置控件之间的绑定关系
tocControl.SetBuddyControl (mapControl);
toolbarControl.SetBuddyControl (mapControl);
//添加命令按钮到toolbarControl
toolbarControl.AddItem ("esriControls.ControlsOpenDocCommand");
toolbarControl.AddItem ("esriControls.ControlsAddDataCommand");
toolbarControl.AddItem ("esriControls.ControlsSaveAsDocCommand");
toolbarControl.AddItem ("esriControls.ControlsMapNavigationToolbar");
toolbarControl.AddItem ("esriControls.ControlsMapIdentifyTool");
//设置空间属性
toolbarControl.BackColor =Color.FromArgb (245, 245, 220);
//挂接事件
mapControl.OnMouseMove +=new IMapControlEvents2_Ax_OnMouseMoveEventHandler(mapControl_OnMouseMove);
}
(5).最后,当程序启动时,加载地图文档
void LoadMap()
{
string strMxd = @"e:\Untitled.mxd";
if (mapControl.CheckMxFile(strMxd))
mapControl.LoadMxFile(strMxd);
}
(6).这样,整个过程就完成了. 完整的代码如下:
MapWindow
using System;
using System.Windows;
using System.Windows.Forms;
using System.Drawing;
using ESRI.ArcGIS.esriSystem;
using ESRI.ArcGIS.Controls;
namespace WPFMapViewer
{
public partial class MapWindow: Window
{
AxMapControl mapControl;
AxToolbarControl toolbarControl;
AxTOCControl tocControl;
public MapWindow ()
{
InitializeComponent ();
CreateEngineControls ();
}
/// <summary>
/// 创建Engine控件并将控件绑定到各自的 WindowsFormsHost 元素上
/// </summary>
void CreateEngineControls ()
{
//设置 Engine 控件到每个host的Child属性上
mapControl = new AxMapControl ();
mapHost.Child = mapControl;
toolbarControl = new AxToolbarControl ();
toolbarHost.Child = toolbarControl;
tocControl = new AxTOCControl ();
tocHost.Child = tocControl;
}
/// <summary>
/// 设置控件相关的属性
/// </summary>
private void SetControlsProperty ()
{
//设置控件之间的绑定关系
tocControl.SetBuddyControl (mapControl);
toolbarControl.SetBuddyControl (mapControl);
//添加命令按钮到toolbarControl
toolbarControl.AddItem ("esriControls.ControlsOpenDocCommand");
toolbarControl.AddItem ("esriControls.ControlsAddDataCommand");
toolbarControl.AddItem ("esriControls.ControlsSaveAsDocCommand");
toolbarControl.AddItem ("esriControls.ControlsMapNavigationToolbar");
toolbarControl.AddItem ("esriControls.ControlsMapIdentifyTool");
//设置空间属性
toolbarControl.BackColor =Color.FromArgb (245, 245, 220);
//挂接事件
mapControl.OnMouseMove +=new IMapControlEvents2_Ax_OnMouseMoveEventHandler(mapControl_OnMouseMove);
}
void LoadMap()
{
string strMxd = @"e:\Untitled.mxd";
if (mapControl.CheckMxFile(strMxd))
mapControl.LoadMxFile(strMxd);
}
private void Window_Loaded (object sender, RoutedEventArgs e)
{
SetControlsProperty();
//加载地图
LoadMap();
}
private void mapControl_OnMouseMove (object sender, IMapControlEvents2_OnMouseMoveEvent e)
{
textBlock1.Text = " X,Y Coordinates on Map: " + string.Format ("{0}, {1} {2}", e.mapX.ToString ("#######.##"), e.mapY.ToString ("#######.##"), mapControl.MapUnits.ToString ().Substring (4));
}
}
}
