"Undo" stops working when using VB

Hi

I have an excel (365) with code in VB.

After I run the module the "undo" stops working, when I remove the VB module the "undo" acts normaly.

What can I do to solve this?

Can the VB code cause this? (I can add it to here) the code copies the comments with the Vlookup function. 

Thanks for your help

    Yes, many VBA commands clear the Undo stack in Excel (any VBA command that modifies something on your spreadsheet). There is nothing you can change about that, other than:
    - Not using that VBA command
    - Looking for an alternative method

    - Use VBA to build our own undo
    To be able to advise we need to see your code.

      Hi

      Thanks for your answer, If there is another way to do it i'll be happy to learn.

      I need the function to do: when I use Vlookup I need to copy not only the value of the relevant cell but also the comment of that cell.

      To do so I found a VBA code in the web that I use.

       

      I will appreciate any workaround to fix it, the function runs only when called (not calculated all the time).

      Following the code I use:

       

      Function VlookupComment(myVal As Variant, myTable As Range, _
      myColumn As Long, myBoolean As Boolean) As Variant
      Application.Volatile True
      Dim res As Variant 'could be an error
      Dim myLookupCell As Range
      res = Application.Match(myVal, myTable.Columns(1), myBoolean)
      If IsError(res) Then
      VlookupComment = 0
      Else
      Set myLookupCell = myTable.Columns(myColumn).Cells(1)(res)
      VlookupComment = myLookupCell.Value
      With Application.Caller
      If .Comment Is Nothing Then
      'do nothing
      Else
      .Comment.Delete
      End If
      If myLookupCell.Comment Is Nothing Then
      'no comment, do nothing
      Else
      .AddComment Text:=myLookupCell.Comment.Text
      End If
      End With
      End If

      End Function

       

       

      Thanks

        To be honest, I would redesign the spreadsheet and move the cell-comments to a separate cell where the comment is entered in the cell as a value so you can use VLOOKUP as designed.
