Why can I not use Private Sub Workbook_Open(ByVal Sh As Object) any workaround?

Question

I want the code to run when workbook loads. I am using Private Sub Workbook_Open(ByVal Sh As Object) , but it throws an error "Procedure error does not match description of event" - Any ideas please, as Private Sub Workbook_SheetActivate(ByVal Sh As Object) works.

But I want code to run when workbook opens.

I know that Private Sub Workbook_Open(ByVal Sh As Object) is not allowed.

See my comment, as previously stated by a few, you can't just change a signature of a standard Excel event handler.

However, you can work within that handler and get access to the worksheets within the workbook.

Private Sub Workbook_Open()
    Dim objSheet As Worksheet

    For Each objSheet In ThisWorkbook.Sheets
        ' Do something with the sheet that you're interested in.
    Next
End Sub

I hope that helps.
