Answer 1

int titleHeight = System.Windows.Forms.SystemInformation.CaptionHeight;
Point myFormPoint = this.PointToScreen(new Point(0,0-titleHeight));
Rectangle rect = new Rectangle(myFormPoint, new Size(this.ClientRectangle.Width,this.ClientRectangle.Height + titleHeight));
System.Windows.Forms.Cursor.Clip = rect;
