注：这是在VS2005环境下的frmMain窗口的代码！

控件有：System.Windows.Forms.Button()              btnStart                       程序开始

              System.Windows.Forms.TextBox()          txtThreadNumber          使用线程数

             System.Windows.Forms.ProgressBar()    progressBar1               工作进度条

             System.Windows.Forms.TextBox()          txtRecoder                    插入纪录数

            System.Windows.Forms.TextBox()           txtInfo                           显示当前使用线程信息

           System.Windows.Forms.DataGridView()   dataGridView1             最后显示插入的数据
