机房收费系统之日结账单和周结账单

       日结和周结其实逻辑是一样的，不过就是日结只结了今天的账，而周结结的是选中日期之间的账。

 一、日结账单

       我日结账单采取的方法是：先判断今天的账结了吗，如果已经结了，就从日结账单表中删除记录，再结一次，如果没有结，就向日结账单表中写入记录。

<span style="font-size:24px;">'在窗体加载时，写日结账单表
'在写日结账单表之前，先判断今天是否已经写过日结账单表了
'如果写过日结账单表了，那么，就删除今天写过的那条，重写今天的日结账记录
'如果，没有，就不重写记录

'日结账单中的计算
'昨日充值卡中余额=读取昨天的日结账单的金额总和
'充值金额=今天充值表中所有的钱
'消费金额=今天学生上机表中，所有的消费金额相加
'退还金额=今天教师退卡表里面，已经（结过账）的退卡总金额
'金额总和=昨日卡中金额+充值金额-消费金额-退还金额
'日期时间是今天的日期时间
