private void Form1_Load(object sender, EventArgs e)
        {
            this.Tag = this.Height + "|" + this.Width;
            foreach (Control o in this.Controls)
            {
                o.Tag = o.Top + "|" + o.Left + "|" + o.Height + "|" + o.Width;
            }
        }
 
        private void Form1_Resize(object sender, EventArgs e)
        {
            foreach (Control o in this.Controls)
            {
                o.Width =(int)(double.Parse(o.Tag.ToString().Split('|')[3]) * (this.Width / double.Parse(this.Tag.ToString().Split('|')[1])));
                o.Height =(int)(double.Parse(o.Tag.ToString().Split('|')[2]) * (this.Height / double.Parse(this.Tag.ToString().Split('|')[0])));
                o.Left =(int)(double.Parse(o.Tag.ToString().Split('|')[1]) * (this.Width / double.Parse(this.Tag.ToString().Split('|')[1])));
                o.Top =(int)(double.Parse(o.Tag.ToString().Split('|')[0]) * (this.Height / double.Parse(this.Tag.ToString().Split('|')[0])));
            }
        }
