Remarks
You can use one of the built-in cursors, or you can set the cursor to a custom cursor. You can use either cursor files (.cur) or icon files (.ico). The cursor is automatically reset when the MouseCursor instance is released. The instance is released when the calling procedure ends, when the variable that references the mouse cursor is set to nothing, or when something, such as the display of a message box, overrides Windows messaging.
The following example uses the built-in wait cursor. The cursor is automatically reset when this Sub procedure ends. You would get m_app from the hook in ICommand::OnCreate().
The following example uses the built-in wait cursor.
void WaitCursor(IApplication app)
{
IMouseCursor appCursor = new MouseCursorClass();
appCursor.SetCursor(2);
for (int i = 0; i <= 10000; i++)
app.StatusBar.set_Message(0, i.ToString());
}
To set a custom cursor, you can get a System.Drawing.Icon object by loading a .ico or a .cur file from its file path or one of your embedded resources.
The following sample loads an icon (.ico) file directlly:
void LoadCustomCursor(IApplication app)
{
System.Drawing.Icon myIcon = new System.Drawing.Icon(@"C:\ArcGIS\Bin\Icons\style.ico");
IMouseCursor appCursor = new MouseCursorClass();
object curIcon = ESRI.ArcGIS.Utility.COMSupport.OLE.GetIPictureDispFromIcon(myIcon);
appCursor.SetCursor(curIcon);
for (int i = 0; i <= 10000; i++)
app.StatusBar.set_Message(0, i.ToString());
myIcon.Dispose();
}
The following sample loads a cursor (.cur) file first and converts it to an icon:
void LoadCustomCursor(IApplication app)
{
System.Windows.Forms.Cursor cur = System.Windows.Forms.Cursors.SizeNESW;
//cur = new System.Windows.Forms.Cursor(@"C:\icons\myCursor.cur");
System.Drawing.Icon myIcon = System.Drawing.Icon.FromHandle(cur.Handle);
IMouseCursor appCursor = new MouseCursorClass();
object curIcon = ESRI.ArcGIS.Utility.COMSupport.OLE.GetIPictureDispFromIcon(myIcon);
appCursor.SetCursor(curIcon);
for (int i = 0; i <= 10000; i++)
app.StatusBar.set_Message(0, i.ToString());
cur.Dispose();
myIcon.Dispose();
}
The following example uses the built-in wait cursor.
Public Sub WaitCursor(app As IApplication)
Dim appCursor As IMouseCursor = New MouseCursorClass
appCursor.SetCursor(2)
For i As Integer = 0 To 10000
app.StatusBar.set_Message(0, i.ToString())
Next
End Sub
