设置 IMapControl2.MouseIcon 鼠标样式

In most development evironments the control's property pages can be used to load either a cursor (.cur) or icon (.ico) file. A cursor contains a custom 'hotspot' location and can be any size. The 'hotspot' location for an icon file defaults to the center of the icon. This property cannot be used to load animated cursor (.ani) files.

To programatically create an object implementing IPictureDisp there is the win32 function OleLoadPicture or helper methods depending on the development environment. 

[C#]

When working directly with AxControls class use the MouseIcon property as follows:

axMapControl1.MouseIcon = new Icon("myIcon.ico");

axMapControl1.MousePointer = esriControlsMousePointer.esriPointerCustom;

When using the Controls interop assembly use the MouseIcon property as follows:

IMapControl2 mapControl = (IMapControl2) axMapControl1.Object;

Icon icon = new Icon(GetType().Assembly.GetManifestResourceStream(GetType(), "myIcon.ico"));

mapControl.MouseIcon = (stdole.IPictureDisp) ESRI.ArcGIS.ADF.COMSupport.OLE.GetIPictureDispFromIcon(icon);

mapControl.MousePointer = esriControlsMousePointer.esriPointerCustom;

[Visual Basic .NET]

When working directly with AxControls class use the MouseIcon property as follows:

AxMapControl1.MouseIcon = New Icon("myIcon.ico")

AxMapControl1.MousePointer = esriControlsMousePointer.esriPointerCustom

When using the Controls interop assembly use the MouseIcon property as follows:

Dim mapControl As IMapControl2 = AxMapControl1.Object

Dim myIcon As Icon = New Icon(GetType(Form1).Assembly.GetManifestResourceStream(GetType(Form1), "myIcon.ico"))

mapControl.MouseIcon = ESRI.ArcGIS.ADF.COMSupport.OLE.GetIPictureDispFromIcon(myIcon)

mapControl.MousePointer = esriControlsMousePointer.esriPointerCustom
