File in use error

P: n/a
I am recieving an error about not being able to use a file because it is
already in use. Based on the error, I think it is referring to my DB, but I
don't know how to avoid the error or why it is happening. Here is the error:

Make sure your Access database file is NOT open in Windows. I.e., make
sure you are closed out of it. I don't know if that's the cause of YOUR
error, but I do know that things can get 'funky' if you have Access
opened, inspecting/modifying your database, and you try to work with it
via an ASP.NET page...

I did not have Access (or any other programs that use Access or any Access
DBs) open at the time. I even tried restarting my computer to make sure
nothing was running in the background, but it did not help.

If you right click on the access DB and choose for properties is the
checkbox 'read-only' checked?
If so uncheck it.

Nathan:

Make sure your closing your connection after you access your data in your
code.

Look for a file LVBEP..ldb on the server in the same dir as the LVBEP.mdb
file. If it it's there, delete it.

If you have access to the IIS Administrator, open the IIS Admin.

Right click the site and click properties. Click the "home Directory" tab
and click the "Unload" button then delete the LVBEP.ldb file.

Then try your connection again. As I said, make extra sure your closing the
connection in your code.

MyOLEDBConnection.Open()

Fill your dataAdapters

MyOLEDBConnection.Close()

By chance, your not developing against a DB that is also in production are
you?

Make sure your Access file is not in the root. Put it in a sub dir of the
root and don't give the "Everyone" account read permissions.

Be sure not to load data directly into a session object. Use sessions
sparingly.
