使用 for 循環和范圍的自定義 VBA 函數

Question

我目前正在嘗試修正我自己的函數，需要一些幫助來循環遍歷一組數據。 我在下面發布的代碼允許我設置兩個變量“CFirstCell”和“CLastCell”（這只是整個函數實際執行的一部分）。 這將返回一個地址（例如：CFirstCell:"$I$4" & CLastCell:"$AL$4"）。

我現在想要獲取這兩個變量並遍歷它們之間的單元格（在名為“客戶端配置”的工作表中），然后獲取那些非空白值並將它們全部存儲為“AllCodes”。 一旦我將所有這些值存儲在數組“AllCodes”中，我想遍歷該數組並打印出包含每個值的消息。 我怎樣才能做到這一點？

一個示例是循環遍歷范圍 I4:AL4，然后返回一個消息框，該消息框將打印出單元格 I4:P4 中的值，因為它們是唯一不為空的值。

Public Function GETHOLDINGS(ClientId, Category, CategoryValue, DisplayValueAs) As String

    Dim ClientName As String
    Dim ReportingType As String    

    Dim CFirstCell As String
    Dim CLastCell As String

    Dim AllCodes As String

    ClientName = WorksheetFunction.Index(Sheets("Client Configuration").Range("Client_Config_Table[[#All],[Client Name]]"), _
    WorksheetFunction.Match(1, Sheets("Client Configuration").Range("Client_Config_Table[[#All],[ID]]")))

    ReportingType = WorksheetFunction.Index(Sheets("Client Configuration").Range("Client_Config_Table[[#All],[Portfolio Reporting Type]]"), _
    WorksheetFunction.Match(1, Sheets("Client Configuration").Range("Client_Config_Table[[#All],[ID]]")))

    CFirstCell = WorksheetFunction.Index(Sheets("Client Configuration").Range("Client_Config_Table[[#All],[C1]]"), _
    WorksheetFunction.Match(1, Sheets("Client Configuration").Range("Client_Config_Table[[#All],[ID]]"))).Address
    CLastCell = WorksheetFunction.Index(Sheets("Client Configuration").Range("Client_Config_Table[[#All],[C30]]"), _
    WorksheetFunction.Match(1, Sheets("Client Configuration").Range("Client_Config_Table[[#All],[ID]]"))).Address

End Function

請試試這個功能。 它應該做你需要的（我從你的話中理解）。 為了理解它是如何工作的，我創建了一個能夠測試它的子：

Sub testGETHOLDINGS()
    Dim sh As Worksheet, rng As Range, CFirstCell As String
    Dim AllCodes As Variant, El As Variant, CLastCell As String
    CFirstCell = "$I$4" 'determine it as you whish or give more
                        'details to find a different way
    CLastCell = "$AL$4" 'determine it as you whish
    Set sh = ActiveSheet 'use here your sheet
    Set rng = sh.Range(CFirstCell & ":" & CLastCell) 'build the range
    AllCodes = GETHOLDINGS(sh, rng) 'use the function to build the
                                    'array of non empty cells value
    If AllCodes = Empty Then Exit Sub 'if rng has more then one row
    For Each El In AllCodes
        Debug.Print El 'it returns in Immediate Window all elements
    Next
End Sub

Private Function GETHOLDINGS(sh As Worksheet, rng As Range) As Variant
  Dim arrC() As String, arrRng As Variant, i As Long, lngEmpty As Long
  Dim nonEmpty As Long, k As Long, rngRow As Long

  rngRow = rng.Cells(1, 1).Row 'determine the range row
  If rng.Rows.count > 1 Then 'stops if rang has more the 1 row
    MsgBox "This function works for one single row range!"
    GETHOLDINGS = Empty: Exit Function
  End If
  'determine how many empty cells are in rng
  lngEmpty = rng.SpecialCells(xlCellTypeBlanks).Cells.count
  nonEmpty = rng.Cells.count - lngEmpty 'non empty cells number
  ReDim arrC(nonEmpty + 1) 'redim the array to the appropriate value
  arrRng = rng.Value 'pass the range values in arrRng array
  For i = 1 To rng.Cells.count 'iterate between the array elements
    If sh.Cells(rngRow, i).Value <> Empty Then
        'load in the array the non empty cells
        arrC(k) = sh.Cells(rngRow, i).Value: k = k + 1
    End If
  Next i
  If arrC(0) <> Empty Then GETHOLDINGS = arrC ' return the array
End Function
