Hi,
I have an ASP.NET app which opens a MS Access database using the Het 4.0 OleDB provider. My development code abd database live on my D drive. Under .NET's Server Explorer I created a connection to the Access database and used this connection in my OleDBConnection object. When I run the app, all works fine.
I then moved the database to my C drive, created the new connection and used it in my app. When opening the database, the following error is generated...
File xxx.mdb is exclusivly opened by another user or, you do not have permission to view its data.
Anyone have any thoughts.

You have a file system permission issue. The user account under which
ASP.Net is running on your machine will need Modify permission for the
folder containing your database.

Hi Mark,
That error usually means that the ASPNET account (or whoever it is
impersonating) doesn't have sufficient permissions to write to the directory
where the .mdb file is located.
When you open an Access database - even for reading - Access needs to create
a locking file. When that can't be done, you get the error you've seen.
Let us know?

Hi Ken, thanks for the info.
I gave "Everyone" and the "ASPNET" accounts Modify permissions on this mdb file, and now the error "Could not lock file" appears.
No one else is using it, and I can open it in Access with no problems.
Note: The mdb that opens fine (on my D drvie) has "Everyone" with Full Control.

You need to give modify rights to the folder the .mdb file is in. Access
wants to create/write to the .ldb file in the same directory.

Here are the specific instructions:
PRB: Cannot connect to Access database from ASP.NET http://support.microsoft.com/default...b;en-us;316675
"Grant read and write permissions for the "Everyone" group on the database
and the database folder. This method is not safe; therefore, Microsoft does
not recommend this method."
