            for(int i=0;i<count;i++)
            {
                TextBox tbox = new TextBox();
                tbox.Size = new Size(30, 50);
                tbox.Location = new Point(50 +tbox.Width, 80);
                tbox.Name = "tbox" + i.ToString();
                this.flowLayoutPanel1.Controls.Add(tbox);
