excel - 在 Sub VBA 中调用用户定义的函数

Question

我是 VBA 新手。我目前正在尝试对用户定义的函数应用循环。定义的函数如下。

  Function CountColor(InRange As range, ColorIndex As Long, _
    Optional OfText As Boolean = False) As Long
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' CountColor
' This function counts the cells in InRange whose ColorIndex
' is equal to the ColorIndex parameter. The ColorIndex of the
' Font is tested if OfText is True, or the Interior property
' if OfText is omitted or False. If ColorIndex is not a valid
' ColorIndex (1 -> 56, xlColorIndexNone, xlColorIndexAutomatic)
' 0 is returned. If ColorIndex is 0, then xlColorIndexNone is
' used if OfText is Fasle or xlColorIndexAutomatic if OfText
' is True. This allows the caller to use a value of 0 to indicate
' no color for either the Interior or the Font.
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

Dim R As range
Dim N As Long
Dim CI As Long

If ColorIndex = 0 Then
    If OfText = False Then
        CI = xlColorIndexNone
    Else
        CI = xlColorIndexAutomatic
    End If
Else
    CI = ColorIndex
End If


Application.Volatile True
Select Case ColorIndex
    Case 0, xlColorIndexNone, xlColorIndexAutomatic
        ' OK
    Case Else
        If IsValidColorIndex(ColorIndex) = False Then
            CountColor = 0
            Exit Function
        End If
End Select

For Each R In InRange.Cells
    If OfText = True Then
        If R.Font.ColorIndex = CI Then
            N = N + 1
        End If
    Else
        If R.Interior.ColorIndex = CI Then
            N = N + 1
        End If
    End If
Next R

CountColor = N


End Function

我正在尝试在 Sub 中使用此函数 CountColor。但它会抛出运行时 424 错误。

Sub Summary()    
    LastColumn = Cells(1, Columns.Count).End(xlToLeft).Column
    LastRow = Cells(Rows.Count, 1).End(xlUp).Row

        For i = 2 To LastRow
        TOTALFAILS = CountColor((range(Cells(i, 4), Cells(i, LastColumn))), 38)
        Cells(i, LastColumn + 8) = TOTALFAILS

        Next i
End Sub

你能帮我找出我做错了什么吗？任何帮助将不胜感激。谢谢

函数调用方式多了一个“(”，导致获取不到正确的参数，试试这个:

CountColor(Range(Cells(i, 4), Cells(i, LastColumn)), 38)

要确保传递预期参数，请在联机时按 Ctrl + I。 VBEditor 会有所帮助:

一般来说，每当使用 Range() 和 Cells() 对象时，请确保引用它们的工作表和工作簿，to avoid 1004 errors 。在本例中，它应该是这样的:

With ThisWorkbook.Worksheets(1)
    For i = 2 To LastRow
        TOTALFAILS = CountColor(.Range(.Cells(i, 4), .Cells(i, LastColumn)), 38)
        .Cells(i, LastColumn + 8) = TOTALFAILS
    Next i
End With
