//調用

 private void Form_Load(object sender, EventArgs e)
        {
            this.Resize += new EventHandler(Form1_Resize);
            X = this.Width;
            Y = this.Height;    


            setTag(this);
            Form1_Resize(new object(), new EventArgs());//x,y可在實例化時賦值,最後這句是新加的，在MDI時有用
