vb6 - 如何在 Visual Basic 6 中查找给定日期的周数？

Question

有没有人在 vb6 中返回给定日期的周数的工作函数？

这曾经有效:

Dim W As Integer

W = Format(DateSerial(2010, 1, 1), "ww", vbMonday, vbFirstFourDays)

但是在 Windows 8.1 中，您现在得到“堆栈空间不足”。

Answer 1

鉴于偏移量，答案有点复杂

以下功能应该可以很好地满足您的需求。只需将一个有效的 Date 对象传递给它，它就会返回一个周数的整数。

Private Function Week(dteValue As Date) As Integer
   'Monday is set as first day of week
   Dim lngDate As Long
   Dim intWeek As Integer

   'If january 1. is later then thursday, january 1. is not in week 1
   If Not Weekday("01/01/" & Year(dteValue), vbMonday) > 4 Then
      intWeek = 1
   Else
      intWeek = 0
   End If
   'Sets long-value for january 1.
   lngDate = CLng(CDate("01/01/" & Year(dteValue)))

   'Finds the first monday of year
   lngDate = lngDate + (8 - Weekday("01/01/" & Year(dteValue), vbMonday))
   'Increases week by week until set date is passed
   While Not lngDate > CLng(CDate(dteValue))
      intWeek = intWeek + 1
      lngDate = lngDate + 7
   Wend
   'If the date set is not in week 1, this finds latest week previous year
   If intWeek = 0 Then
      intWeek = Week("31/12/" & Year(dteValue) - 1)
   End If
   Week = intWeek
End Function
