主题：关于设置信用卡还款日

1、认认真真看懂42楼；

2、对表格进行排序 http://www.foxtable.com/webhelp/scr/0451.htm

1、那就循环每一行，移动行 http://www.foxtable.com/webhelp/scr/1846.htm

2、ndr("免息天数") = iif((enddate - Date.today).TotalDays>5, (enddate - Date.today).TotalDays, -1 * (enddate - Date.today).TotalDays)

3、没看懂你要做什么。

比如 ndr("结束记账日") = enddate.AddMonths(1)

2、比如 ndr("结束记账日") = enddate.AddMonths(1)

起始日、结束日，没问题，只有到期还款日，需要重新计算，如

Dim dt_xyk As DataTable = DataTables("信用卡")
Dim dt_lsz As DataTable = DataTables("流水账")
Dim dt_yk As DataTable = DataTables("用卡")
dt_yk .DataRows.Clear
Dim d As Date = new Date(Date.Today.Year, Date.Today.Month, 1)
Dim ds() As Date = {d, d.AddMonths(1)}
d = d.AddMonths(-1)
For Each dr As DataRow In dt_xyk.DataRows
    Dim ndr As DataRow = dt_yk .AddNew
    ndr("卡号") = dr("卡号")
    ndr("账户名称") = dr("账户名称")
    ndr("信用额度") = dr("信用额度")
    ndr("账单日") =dr("账单日")
    ndr("还款日") =dr("还款日")
    ndr("可用额度") = ndr("信用额度") -(dt_lsz.Compute("sum(金额)", "账户名称 = '" & ndr("账户名称") & "' and 类别 = '转出'"))-(dt_lsz.Compute("sum(金额)", "账户名称 = '" & ndr("账户名称") & "' and 类别 = '转入'"))
    If dr("账单日")+1 <= Date.today.day Then
        ndr("起始记账日") = d.AddDays(dr("账单日")).AddMonths(1)
        ndr("结束记账日") = d.AddDays(dr("账单日")-1).AddMonths(2)
    Else
        ndr("起始记账日") = d.AddDays(dr("账单日")).AddMonths(0)
        ndr("结束记账日") = d.AddDays(dr("账单日")-1).AddMonths(1)
    End If
    ndr("固定还款日") = dr("固定还款日")
    If dr("固定还款日") = False Then
        ndr("到期还款日") = cdate(ndr("结束记账日")).AddDays(dr("还款日"))
