我在Access中有一些VBA代码,它从Excel工作表中获取一系列单元格,然后将它们从数字转换为日期。例如,范围是H1:Y25000
Public Sub FixDates(theRange as Range)
Dim RangeCell as Range
For Each RangeCell In theRange
If IsNumeric(RangeCell.Value) And RangeCell.Value > 0 And Not IsEmpty(RangeCell.Value) Then
lngDate = CLng(RangeCell.Value)
RangeCell.Value = DateAdd("d", lngDate -1, "1/1/1968")
End If
Next RangeCell
End Sub
代码似乎有效,但运行时间可能很长。这可以用不同的方式写得更快吗?我正在阅读使用Variant而不是Range,但我无法弄明白。
哦,要打电话给Sub,我会使用类似的东西:
path = "C:\myfile.xlsx"
Set xlApp = CreateObject("Excel.Application")
Set xlWbk = xlApp.Workbooks.Open(path)
Set xlWks = xlWbk.Worksheets(1)
lastRow = xlWks.Range("A1").End(xlDown).Row
FixDates (xlWks.Range("H1:Y" & lastRow))
谢谢!

您可以简单地将范围分配给变量,这将创建一个数组 - 它看起来像下面的代码 - 您应该添加适当的错误处理:
Public Sub FixDates(theRange as Range)
Dim data as Variant
Dim i as Long
Dim j as Long
Dim lngDate as Long
data = theRange
For i = LBound(data, 1) to UBound(data, 1)
For j = LBound(data, 2) to UBound(data, 2)
If IsNumeric(data(i, j)) Then
If data(i, j) > 0 Then
lngDate = CLng(data(i, j))
data(i, j) = DateAdd("d", lngDate - 1, "1/1/1968")
End If
End If
Next j
Next i
theRange = data
End Sub
