 主窗体退出时写FormClosed事件函数，调用CloseExe()函数

 在控件改变大小的时候，重新MoveWindow()即可，如：
         private void splitContainer1_Panel2_Resize(object sender, EventArgs e)
         {
             if (this.appWin != IntPtr.Zero)
             {
                 MoveWindow(appWin, , , this.splitContainer1.Panel2.Width, this.splitContainer1.Panel2.Height, true);
             }
             base.OnResize(e);
         }
