如何自动填充公式VBA

Question

我正在尝试制作一个宏，它将从其他报告中复制范围并将它们放入一个大报告中。 范围复制工作正常，并且确实应该如此。 我现在遇到的问题是如何使用vba获取日历周日期（日历周的星期一）。 我知道要做到这一点的excel公式，但我似乎无法弄清楚如何在vba中实现。

= DATE（包含年份的单元格，1，-2）-WEEKDAY（DATE（包含年份的单元格，1,3））+具有日历周编号的单元格（即日历周13）* 7

处理每个日历周的星期一日期的最佳方法是什么？

我尝试的当前自动填充方法给我一个运行时错误'1004：Range类的自动填充方法失败。

根据MSDN，自动填充要求源是目标的一部分（ https://stackoverflow.com/a/1528853/2832561 ）

回顾你的代码......

Set firstCellD = ws.Range("B7").End(xlDown)
'Offset to get the next empty row
Set firstCellD = firstCellD.Offset(1, 0)
'Set lastCellD = the bottom cell of column C
Set lastCellD = ws.Cells(Rows.Count, "C").End(xlUp)
'Offset by one column to get target column
Set lastCellD = lastCellD.Offset(0, -1)
'Create composit range in targer column
Set rcw = Range(firstCellD, lastCellD)
rcw.Value = cw

在上面之后， firstCellD和lastCellD都在列“B”中。

'put year in destination sheet
Set firstCellD = firstCellD.Offset(0, 11)
Set lastCellD = lastCellD.Offset(0, 11)
Set ry = Range(firstCellD, lastCellD)
ry.Value = year

这里，它们偏移到列“N”。

'get calendar week date
Set firstCellD = firstCellD.Offset(0, -1)
Set lastCellD = lastCellD.Offset(0, -1)
Set rdw = Range(firstCellD, lastCellD)
'Here is where the error occures
'********************************************************************
Range("p1").Autofill Destination:=Range(firstCellD, lastCellD), Type:=xlFillDefailt
'********************************************************************
Set firstCellD = firstCellD.Offset(0, -1)
Set lastCellD = lastCellD.Offset(0, -1)
Set rm = Range(firstCellD, lastCellD)
'get month from the calendar week date
'rm.Formula = datepart(month)

在错误之前，它们再次偏移，左边一列：“M”。 由于“P1”不在“M”列的范围内，因此自动填充功能失败。

我建议将公式复制到firstCellD ，然后使用它作为自动填充的源，假设“P1”中的公式使用适当的相对寻址。

TL; DR和对评论的回应：

您的代码目前正在尝试将公式从“P1”自动填充到由“ Range(firstCellD, lastCellD)定义的“M”列中的单元格范围内。 这不起作用，因为自动填充要求填充的源单元格成为目标范围的一部分，就像您通过拖动单元格右下角的填充柄手动操作一样。 如果“P1”中的公式确实应该填充到“M”列的指定单元格中，则应首先将公式复制到firstCellD ，然后从firstCellD执行自动填充到范围的其余部分。 执行此操作的两行代码是：

Range("P1").Copy firstCellD
firstCellD.Autofill Destination:=Range(firstCellD, lastCellD), Type:=xlFillDefault

制作Excel文档的备份副本并试一试！

Answer 2

我只是将我需要的公式放在另一张表中，将公式复制到剪贴板，然后使用pasteSpecial，而不是使用自动填充。

ws2.Range("L1").Copy
rdw.PasteSpecial (xlPasteAll)
