对于机房收费的结账,我感觉是所有窗体中,最难的一个。这个窗体我真的做了好多天。它的难度系数我感觉是最高的。
首先,你要理清上机时间和收费标准的关系,在预备时间中,是不收费的。
其次,在超过预备时间,一个单位时间之内,收一个费用。在一个单位时间到两个单位时间内,收两个单位时间的费用。
然后,在结账窗口,链接数据库,显示出所有该用户未结账的信息。
最后,在点击结账时,这个用户的所有未结账信息都结账,并写入数据库。结账窗口查询类信息都为0。并把结账信息写入结账表。已被制作报表使用。
在做结账窗体时,主要是理清思路,这样做起来就容易很多了。我把我的结账窗体和代码放在下面,不做详细的解说,只是给自己留个思路,读者一个方法。
代码仅供参考:
