系统采用ASP.NET4.0 无需数据库。
在企业抽奖时，请勿关闭或者刷新页面。因为系统目前没有提供保存数据功能。
例如在抽二等奖和一等奖之间，可能有时间间隔。
那么，此时，你可以按F11取消全屏，然后最小化页面，再单击右下角喇叭，设置无声。(The system uses ASP.NET4.0 without database.
Do not shut down or refresh the page when the company draws raffle. Because the system does not provide data saving function at present.
For example, there may be a time interval between the two prize and the first prize.
At this point, you can cancel the full screen according to F11, then minimize the page, and then click the lower right horn to set up the silent.)
