Hi all,
I am using VBA to open a workbook on a network drive with following code:

Sub OpenMyfolder()
Application.DisplayAlerts = False
Workbooks.Open("P:\MyFolder\MyBook.xls")
Application.DisplayAlerts = True
End Sub

Code works fine however, if workbook is already open on network drive, you
get a prompt to say file is in use with options to Open as Read Only, Wait or
Cancel.

My question is, can I prevent this message showing if File is already open?
& if it is, default to open the file as ReadOnly?
I have used Application.DisplayAlerts = False but this did not work. Also,I
am not too sure how I should write the reuqired code to open as readonly in
such event.

Hope clear - any help / guidance appreciated.

Take a look at this function. The example is using MS Word but it should do
the trick for you.

Steve,
thanks for response - I have tried using functions posted at various sites
to test if File is Open - but still get the message File In Use!
