how to display map co-ordinates for the mouse position + Mapextreme

1. Add this line to public MapForm1():

mapControl1.MouseMove += new MouseEventHandler(MapControl1_MouseMove);

2. Add this function to the project:

public void MapControl1_MouseMove(object sender, MouseEventArgs e)
{
System.Drawing.PointF DisplayPoint = new PointF(e.X,e.Y);
MapInfo.Geometry.DPoint MapPoint = new MapInfo.Geometry.DPoint();

MapInfo.Geometry.DisplayTransform converter = this.mapControl1.Map.DisplayTransform;
converter.FromDisplay(DisplayPoint, out MapPoint);

this.statusBar1.Text = "Cursor Location: " + MapPoint.x.ToString() + ", " + MapPoint.y.ToString();
}

This will display the current coordinates of the mouse position.
