关于ArcEngine中自定义光标的问题

<P>请问，如何在图层控制时拖动图层自定义光标，我在帮助上找到了一下代码，但不知道怎么使用，大家帮忙看看：</P><PRE><CODE>Dim pTOCControl As ITOCControl
pTOCControl = AxTOCControl1.Object
Dim pIcon As Icon
pIcon = New Icon(GetType(Form1).Assembly.GetManifestResourceStream(GetType(Form1), "myIcon.ico"))
pTOCControl.MouseIcon = ESRI.ArcGIS.Utility.COMSupport.OLE.GetIPictureDispFromIcon(pIcon)
pTOCControl.MousePointer = esriControlsMousePointer.esriPointerCustom</CODE></PRE><PRE><CODE>关键是这一句  pIcon = New Icon(GetType(Form1).Assembly.GetManifestResourceStream(GetType(Form1), "myIcon.ico"))
是什么意思啊？</CODE></PRE>
