XL2000: Cannot Programmatically Close Referenced Workbook

Symptoms

When you run a macro that attempts to close a workbook, you may receive the following error message:

Run-time error '1004': This workbook is currently referenced by another workbook and cannot be closed.

Cause

This problem occurs when you set an object variable to a workbook that references another workbook, and then attempt to close the referenced workbook.



You cannot close a workbook while that workbook is referenced by another open workbook or by an object variable that is set to the referenced workbook.



For example, if Book2.xls contains a reference to Book1.xls, then the following macro produces the error when the macro attempts to close Book1.xls:


   Sub OpenClose()
Dim wb1, wb2
'Open the workbooks and set the object variables
Set wb1 = Workbooks.Open("Book1.xls")
Set wb2 = Workbooks.Open("Book2.xls")
'Close both workbooks
wb2.close
wb1.close ' ---- This line produces the error
End Sub

Resolution

To correct this problem, set the object variable for the workbook that contains the reference to Nothing prior to closing the referenced workbook. By setting the object variable to Nothing, it no longer refers to the workbook. The macro below demonstrates how to set the object variable to Nothing so that the referenced workbook can be closed programmatically:

   Sub OpenClose()
Dim wb1, wb2
'Open the workbooks and set the object variables
Set wb1 = Workbooks.Open("Book1.xls")
Set wb2 = Workbooks.Open("Book2.xls")
'Close book2
wb2.close
'Set the object variable wb2 to Nothing
Set wb2 = Nothing
'Close book1
wb1.close
End Sub
