VB Is a workbook open
 

In running a Visual Basic macro in Excel 2002, I have the
following situation.

The macro opens another workbook (that already exists) to
read and write some values in it.
If the other workbook is already open, then it has to be
closed and reopened each time (in response to a dialog
box) or the macro terminates.
I would like to omit the request to open the other
workbook in the event that it is already open. But I
cannot find any function in Visual Basic that can return
the status of the other workbook (i.e., whether or not it
is already open).

Hi Linda,

Dim WB as Workbook

On Error Resume Next
Set WB = Workbooks("YourWorkbookName")
On Error Goto 0

If Not WB is Nothing Then
'Workbook is open
Else
'Workbook not open
End if
