在学VFP时,首先看到的就是在数据库表中可以定义字段级规则和记录级规则,有人用过吗?我想很少。为什么?因为正常情况下,所定义的规则,是数据库引擎所产生的错误提示,很不美观。用VFP的表单向导做的表单,很好的解决了这个问题。它是如何解决的呢?我不知道有人是否对这个问题耿耿于怀,反正我是这样。N年后,我终于明白了它该如何来使用。你呢?还不明白?下载文件看看吧。也许,可以改变很多你对VFP的认识。来自我站:http://www.chinavfp.com-school VFP, is the first to see the tables in the database field can be defined rules and record-level rules, It was used? I think very few. Why? Because under normal circumstances, as defined in the rules, is a database engine from the errors, and it is very beautiful. VFP form with the Wizard do form, a good solution to the problem. How has it been resolved? I do not know whether it was the right heart, I do anyway. N years later, I finally understand how it used to. You? Still not understand? Download and watch it. Perhaps, you can change many of VFP awareness. From my station : http://www.chinavfp.com
