Hi,

when someone opens a workbook which already was opened by someone else,
the
person gets a dialogbox, inwhich (s)he can select 'read only'.

But when the user opens the workbook through a script, the user is not
warned.

I want to stop the script if the opened workbook was already opened by
someone else.

How do I determine this?

Thanks
