实用的c#实用软键盘

【调用键盘代码】

TextBox t = (TextBox)sender;
            MyControls.KeyBorad k = new MyControls.KeyBorad(t);
            k.Location = new Point(t.Location.X 200, t.Location.Y);

            //使控件可移动
           // ControlMoveResize c = new ControlMoveResize(k, this);
            this.Controls.Add(k);
            //置于顶层
            k.BringToFront();
