excel - 无法在函数内将数据写入 Excel 2007/2010 中的 VBA 单元格

Question

我想通过 VBA 设置单元格的值。我用谷歌搜索，看到了一些解决方案:

Sheets("SheetName").Range("A1").value = someValue
Sheets("SheetName").Cells(1,1).value = someValue

使用这种代码，我只能从单元格 A1 读取数据，但无法为其设置新值。

更新

设置单元格 A1 值的代码位于 Function 中，如下所示。

Function abb()
    Sheets("SheetName").Range("A1").value = 122333
    abb = 'any thing'
End Function

在单元格 B2 中，我设置 =abb() 并按 Enter 键。我得到#VALUE，但 A1 没有任何反应。

将此代码放入宏中，它可以工作。

我的问题是，如何使 A1 在函数内具有值？

Answer 1

根据您上面的评论，您想尝试这种方法

如果您输入
=abb()
进入任何单元格

然后该工作表的单元格 A1 将设置为 12333

这是要更新的行，用于选择要更新的单元格，并在其中放置一个值
范围(“A1”).Value = 122333

来自I don't want my Excel Add-In to return an array (instead I need a UDF to change other cells)

I am reposting this piece of magic from Kevin Jones aka Zorvek as it sits behind the EE Paywall (link attached if anyone has access)

While Excel strictly forbids a UDF from changing any cell, worksheet, or workbook properties, there is a way to effect such changes when a UDF is called using a Windows timer and an Application.OnTime timer in sequence. The Windows timer has to be used within the UDF because Excel ignores any Application.OnTime calls inside a UDF. But, because the Windows timer has limitations (Excel will instantly quit if a Windows timer tries to run VBA code if a cell is being edited or a dialog is open), it is used only to schedule an Application.OnTime timer, a safe timer which Excel only allows to be fired if a cell is not being edited and no dialogs are open.

The example code below illustrates how to start a Windows timer from inside a UDF, how to use that timer routine to start an Application.OnTime timer, and how to pass information known only to the UDF to subsequent timer-executed routines. The code below must be placed in a regular module.

Declare Function SetTimer Lib "user32" ( _
      ByVal HWnd As Long, _
      ByVal nIDEvent As Long, _
      ByVal uElapse As Long, _
      ByVal lpTimerFunc As Long _
   ) As Long

Private Declare Function KillTimer Lib "user32" ( _
      ByVal HWnd As Long, _
      ByVal nIDEvent As Long _
   ) As Long

Private mCalculatedCells As Collection
Private mWindowsTimerID As Long
Private mApplicationTimerTime As Date

Public Function abb()

' This is a UDF that returns the sum of two numbers and starts a windows timer
' that starts a second Appliction.OnTime timer that performs activities not
' allowed in a UDF. Do not make this UDF volatile, pass any volatile functions
' to it, or pass any cells containing volatile formulas/functions or
' uncontrolled looping will start.

   abb = "Whatever you want"

   ' Cache the caller's reference so it can be dealt with in a non-UDF routine
   If mCalculatedCells Is Nothing Then Set mCalculatedCells = New Collection
   On Error Resume Next
   mCalculatedCells.Add Application.Caller, Application.Caller.Address
   On Error GoTo 0

   ' Setting/resetting the timer should be the last action taken in the UDF
   If mWindowsTimerID <> 0 Then KillTimer 0&, mWindowsTimerID
   mWindowsTimerID = SetTimer(0&, 0&, 1, AddressOf AfterUDFRoutine1)

End Function

Public Sub AfterUDFRoutine1()

' This is the first of two timer routines. This one is called by the Windows
' timer. Since a Windows timer cannot run code if a cell is being edited or a
' dialog is open this routine schedules a second safe timer using
' Application.OnTime which is ignored in a UDF.

   ' Stop the Windows timer
   On Error Resume Next
   KillTimer 0&, mWindowsTimerID
   On Error GoTo 0
   mWindowsTimerID = 0

   ' Cancel any previous OnTime timers
   If mApplicationTimerTime <> 0 Then
      On Error Resume Next
      Application.OnTime mApplicationTimerTime, "AfterUDFRoutine2", , False
      On Error GoTo 0
   End If

   ' Schedule timer
   mApplicationTimerTime = Now
   Application.OnTime mApplicationTimerTime, "AfterUDFRoutine2"

End Sub

Public Sub AfterUDFRoutine2()

' This is the second of two timer routines. Because this timer routine is
' triggered by Application.OnTime it is safe, i.e., Excel will not allow the
' timer to fire unless the environment is safe (no open model dialogs or cell
' being edited).

   Dim Cell As Range

   ' Do tasks not allowed in a UDF...
   Application.ScreenUpdating = False
   Application.Calculation = xlCalculationManual
   Do While mCalculatedCells.Count > 0
      Set Cell = mCalculatedCells(1)
      mCalculatedCells.Remove 1
      Range("A1").Value = 122333
   Loop
   Application.Calculation = xlCalculationAutomatic
   Application.ScreenUpdating = True
   End Sub
