        {
            InitializeComponent（）;
        }

        FrmSelectFriend frmSelectFriend = new FrmSelectFriend（）;
        //查找按钮，显示查找子窗体
        private void tsmiSelect_Click（object sender EventArgs e）
        {
            if （frmSelectFriend.IsDisposed == true）
            {
                frmSelectFriend = new FrmSelectFriend（）;
            }
            frmSelectFriend.MdiParent = this;
            frmSelectFriend.Show（）;
        }

        //关闭窗体
        private void tsmiExit_Click（object sender EventArgs e）
        {
            this.Close（）;
        }

        //添加信息按钮，显示添加信息子窗体
        FrmAddFriend frmAddFriend = new FrmAddFriend（）;
        private void tsmiAdd_Click（object sender EventArgs e）
        {
            if （frmAddFriend.IsDisposed == true）
            {
                frmAddFriend = new FrmAddFriend（）;
            }
            frmAddFriend.MdiParent = this;
            //添加与修改使用同一窗体，用Tag值进行区分，0表示添加窗体，1表示修改窗体
            frmAddFriend.tag = 0;
            frmAddFriend.Show（）;
        }
    }
