Excel 代码行中的宏错误

我有一个宏，将a列中的每个数字加上零，直到数字中有7个总数字，直到今天为止，它工作正常，我在1=I=1到endrow=-1的行中得到一个错误，我无法理解它的含义

代码是

Sub AddZeroes()
'Declarations
Dim i As Integer, j As Integer, endrow As Long
'Converts the A column format to Text format
Application.ScreenUpdating = False
Columns("A:A").Select
    Selection.NumberFormat = "@"
'finds the bottom most row
endrow = ActiveSheet.Range("A1").End(xlDown).Row
'selects the top cell in column A
ActiveSheet.Range("A1").Select

'loop to move from cell to cell
For i = 1 To endrow - 1
                'Moves the cell down 1. Assumes there's a header row so really starts at row 2
                ActiveCell.Offset(1, 0).Select
                'The Do-While loop keeps adding zeroes to the front of the cell value until it hits a length of 7
    Do While Len(ActiveCell.Value) < 7
                                ActiveCell.Value = "0" & ActiveCell.Value
                Loop
Next i
Application.ScreenUpdating = True
End Sub

我可能已经达到了整数32767的上限。行返回Long，所以我应该是Long，就像EndRow一样

只要我重新编写了您的代码，我就会：

Sub test()
    Dim c As Range, rngTarget As Range
    Set rngTarget = Range("A:A").SpecialCells(xlCellTypeConstants, xlNumbers)
    rngTarget.NumberFormat = "@"
    For Each c In rngTarget
        c.Value = Left(c.Value & "0000000", 7)
    Next c
End Sub

更清晰更快。

那么我该如何修复它呢？到目前为止，我已经用过几十次了。我只用了10行就试过了，但它仍然有效。我正试图在即时窗口中看到这个问题。按照iDevelop的建议，将整数声明更新为Long。您可能会发现这是获取结束行的更好方法：endrow=ActiveSheet.CellsRows.Count，1.EndxlUp.row
