Excel VBA用户定义函数，可使用条件格式对单元格进行计数 [英] Excel VBA User Defined Function that counts cells with conditional formatting

问题描述

我正在尝试编写一个UDF，该UDF对具有条件格式的单元格的数量进行计数.我写了下面的子程序，看起来很像魅力:

I am trying to write a UDF that counts the number of cells that have conditional formatting. I wrote the following sub that works like a charm:

Sub SumCountByConditionalFormat()
Dim cellrngi As Range
Dim cntresi As Long

cntresi = 0

Set cellrngi = Sheets("Sheet3").Range("I2:I81")

For Each i In cellrngi
    If i.DisplayFormat.Interior.Color <> 16777215 Then
    cntresi = cntresi + 1
    End If
Next i
end sub

，我尝试使用以下代码将其转换为UDF:

and I tried to convert it to a UDF with the following code:

Function CountCellsByColor1(rData As Range) As Long
Dim cntRes As Long

Application.Volatile
cntRes = 0
For Each cell In rData
    If cell.DisplayFormat.Interior.Color <> 16777215 Then
        cntRes = cntRes + 1
    End If
Next cell

CountCellsByColor1 = cntRes
End Function     

但是，当我尝试UDF时，我得到一个#VALUE！回来.我真的不确定为什么，任何帮助将不胜感激.

However when I try the UDF i get a #VALUE! returned. I'm really not sure why and any help would be much appreciated.

推荐答案

您可以解决无法使用Evaluate

Function DFColor(c As Range)
    DFColor = c.DisplayFormat.Interior.Color
End Function


Function CountCellsByColor1(rData As Range) As Long
    Dim cntRes As Long, clr As Long, cell As Range
    cntRes = 0
    For Each cell In rData.Cells
        'Evaluate the formula string in the context of the
        '  worksheet hosting rData
        clr = rData.Parent.Evaluate("DFColor(" & cell.Address() & ")")
        If clr <> 16777215 Then
            cntRes = cntRes + 1
        End If
    Next cell
    CountCellsByColor1 = cntRes
End Function
