"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The most important difference is this:

auto_open will not run when the workbook is opened by a macro. workbook_open will run if the workbook is opened by a macro.

In the first case (Auto_Open), you can use Workbook.RunAutoMacros to run the macro after opening the workbook.

Cheers,

Hi thandel,

Leo is correct.  I would just add that if you open a workbook with a Workbook_Open sub via code, you can keep
the event from firing with the line:

    Application.EnableEvents = False

right before you open it.  Be sure to turn events back on, though!

Regards,

Patrick

workbook_open executes first
thandelAuthor Commented:
Can you think of any reason why it wouldn't excute at all provided the workbook contained both and macros security etc was set to run?
GrahamSkanRetiredCommented:
Both would execute. The main difference is that Microsoft want to disown the Auto_Open, so support for that is likely to disappear at some unspecified time.
Leo EikelmanDirector, IT and Business DevelopmentCommented:
hmm doesn't execute at all?

If Application.EnableEvents = True then Is the Sub Workbook_Open() in the code view behind the workbook object (it needs to be).

As far as I understood this event should always fire in these circumstances, bit if it still doesnt then you could alternatively use Sub Auto_Open() in any code module (this should
also work regardless of whether Excel has events disabled).

there may be something wrong with the document.  Would it be difficult to move everything to a new document?
