Hello,

I am using the "Application.FollowHyperlink strFilePath, , True" line
of code from within access forms to launch any file type I want (e.g.,
xls, doc, pdf, etc.). The files open up okay, but open up in the
background. How do I make them open in front where they are visible?
I have tried various things like "Appliction.Visible=True / False"
and "Screen.ActiveControl.Visible=True / False" but have not been able
to figure it out.

Anyones help with this would be very much appreciated.

Regards,

Ruben Munoz

Ron,

Thanks very much for the sample code provided.  The ShellExecute part
of the code work great!  Is there any way to redirect the focus to
access upon closing the external file just launched?  Otherwise, I can
certainly work with this.

Ruben

Glad the code helped.
The ShellExecute function returns after attempting to open the file with
success or fail. At that point your Access application has no control over
the shelled application. Maybe check with the "Dev Ashish" who originally
posted the code, maybe there is a shell api that will wait for the shelled
to application to close.- Hide quoted text -

Ron,

Thanks again for your help on this. It gives something more to work
with.

Ruben
