Implemented in C # code description:

private void DrawComment()
{
    MxDrawComment com = new MxDrawComment();

    MxDrawPoint pt = new MxDrawPoint();
    pt.x = 200;
    pt.y = 200;
    com.basePoint = pt;

    pt.x = 300;
    pt.y = 300;

    com.Position = pt;
    com.Text = "Test";

    MxDrawPoints pts = new MxDrawPoints();
    pts.Add(-100, -100, 0);
    pts.Add(100, 100, 0);

    com.Bounding = pts;

    com.ArrowType = 2;

    com.BoundingBoxType = 5;

    com.Bounding = pts;

    com.ShapRadius = 50;

    com.TextHeight = 100;

    axMxDrawX1.DrawEntity(com);

    axMxDrawX1.ZoomAll();
