}



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, 0, 0, this.splitContainer1.Panel2.Width, this.splitContainer1.Panel2.Height, true);
            }
            base.OnResize(e);
        }
