[英]Excel VBA - Week Ending Date
B 列是我的数据 - 如果 B 列中有日期值,请在 C 列中返回周结束日期。需要 VBA 代码来完成此操作
Column B Column C
11/9/2016 11/11/2016
11/8/2016 11/11/2016
4/4/2017 4/7/2017
(blank) (blank)
3/28/2017 3/31/2017
下面是我能得到的所有,但它没有任何好处。
Dim FirstDayInWeek, LastDayInWeek As Variant
Dim dtmDate As Date
dtmDate = Range("B2:B")
LastDayInWeek = dtmDate - Weekday(dtmDate, vbUseSystem) + 7
MsgBox LastDayInWeek
我回复了您关于如何从给定日期找到一周开始日期的评论? ,但这里是一个答案:
Function ReturnDate(DateRange As Date, Optional DayInWeek = 1) As Date
ReturnDate = DateRange - Weekday(DateRange, vbUseSystem) + DayInWeek
End Function
=ReturnDate(A1)
给出星期一
=ReturnDate(A1,2)
给出星期二
.
=ReturnDate(A1,5)
给出 Friday < --- 这是你想要的。
=ReturnDate(A1,7)
给出星期日。
空白单元格将给出01/01/1900
,但您可以为此添加检查或将单元格格式化为不显示 0。
也许你可以采用下面的方法
Sub ReturnWeekEndDate()
Dim InpRng As Range
Dim i As Long
Set InpRng = ActiveSheet.Range("A2:B5")
For i = 1 To InpRng.Rows.Count
If IsDate(InpRng.Cells(i, 1).Value) And IsDate(InpRng.Cells(i, 2).Value) Then
InpRng.Cells(i, 1).Offset(0, 2) = InpRng.Cells(i, 1).Value - Weekday(InpRng.Cells(i, 1).Value, vbUseSystem) + 7
End If
Next i
End Sub
试试这个:
Sub INeedADate()
Dim i As Long, N As Long, r As Range, Bigr As Range
N = Cells(Rows.Count, "B").End(xlUp).Row
For i = 1 To N
Set r = Cells(i, "B")
If IsDate(r.Value) Then
addy = r.Address
r.Offset(0, 1).Value = Evaluate(addy & "-WEEKDAY(" & addy & ",3)+IF(WEEKDAY(" & addy & ",3)>4,11,4)")
End If
Next i
End Sub
这类似于使用工作表公式:
=B1-WEEKDAY(B1,3)+IF(WEEKDAY(B1,3)>4,11,4)
或者试试这个...
Sub GetFridayDate()
Dim LastDayInWeek As Date
Dim Rng As Range, Cell As Range
Dim lr As Long
lr = Cells(Rows.Count, 2).End(xlUp).Row
Set Rng = Range("B2:B" & lr)
For Each Cell In Rng
If IsDate(Cell.Value) Then
LastDayInWeek = Cell + 8 - Weekday(Cell, vbFriday)
Cell.Offset(0, 1) = LastDayInWeek
End If
Next Cell
End Sub
你说这将是一个过程的一部分......所以,只要像我展示的那样调用这个函数,你就是金子! 繁荣!
Sub FindEndOfWeek_Test()
Call FindEndOfWeek(ActiveSheet, 1, 2, 6, 1)
End Sub
Function FindEndOfWeek(Sht As Worksheet, KnownDate_Column As Integer, _
EndOfWeek_Column, EndOfWeek As Integer, _
StartingRow As Long)
' This function takes in a spreadsheet, and and determines the date at the end
' of the week, based on known parameters being passed into the function.
'
Dim a As Long
Dim LastRow As Long
Dim EvalDate As Date
Dim NewDate As Date
' Determine the last row of the column you are working with
LastRow = Sht.Cells(Sht.Rows.Count, KnownDate_Column).End(xlUp).Row
' Loop through your entire spreadsheet to determine the end of the week for all rows
For a = StartingRow To LastRow
If IsDate(Sht.Cells(a, KnownDate_Column).Value) = True Then
NewDate = Sht.Cells(a, KnownDate_Column).Value
EvalDay = Weekday(NewDate)
' Determine the known date day of the week, and add accordingly.
If EvalDay < EndOfWeek Then
Sht.Cells(a, EndOfWeek_Column).Value = NewDate + (EndOfWeek - EvalDay)
ElseIf EvalDay > EndOfWeek Then
Sht.Cells(a, EndOfWeek_Column).Value = NewDate + (7 - EvalDay + EndOfWeek)
Else
Sht.Cells(a, EndOfWeek_Column).Value = NewDate
End If
End If
Next a
End Function
如果您真的需要 VBA 代码来解决这个问题,我就是这样做的,您可以将 excel 公式转换为单行解决方案,如下所示:
WeekendingDate = Date + 7 - WorksheetFunction.Weekday(Date + 7 - 6)
