I created a windows application, added a Grid Control  and connected to the
Pubs.mdb Access database locally with no trouble. Next I copied Pubs to a
WebServer, changed the connection string by providing the IP address of the
web server but the error below occurs.  I tried the domain name ( like
ibm.com\Folder) for the server and that failed also. I don't think I'm even
attempting to hit on the server!  The error is shown below

An OleDBException was unhandled   ==>
Me.AuthorsTableAdapter.Fill(Me.PubsDataSet.authors)

Error : Cannot start your application. The workgroup information file is
missing or opened exclusively by another user.

TIA

Workgroup (system database):

Last Clean Version Used (Language VB.Net Express 2005) :
As per Paul
Code below lives in the app.confi file

<connectionStrings>

<add name="CRUD.My.MySettings.PubsConnectionString"

I did not create a Workgroup information file so it probably does not exist
on the server!
Is this a step I missed ???

------------------------------------------------------------------------------------------
Paul Clement MVP Suggests : : :
I tried and it still fails with the same error

Workgroup (system database):
"Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=www.test.com\somepath\mydb.mdb;
Jet OLEDB:System Database=system.mdw;"



With password:

"Provider=Microsoft.Jet.OLEDB.4.0;

Jet OLEDB:Database
Password=MyDbPassword;"

Make sure on your webserver that you enable read/write/execute
permissions on the folder and the database file.

I checked and was told that the permissions are set to
read/write/execute on both the folder and the database file.
Now, as I see it, the Pubs.mdb database lives in a folder on the webserver
with the appropriate permissions.
Using the connection string previously discussed, I ought to be able to get
access to that database and display records in the GridView on a client
machine.
Is this correct ?
Is there some example of a mdb (perhaps Pubs.mdb)  living on some server
that is publically accessible using VB.Net ?
Still Stuck

Bob,

Are you sure of that because the ASPNET user is ASPNET.

Cor

Thanks, I got past one error and now have another.

My Assumptions:
1. One can use VB.Net Express 2005 to write a client resident application to
access an .mdb file living on a remote server.
2. No Microsoft Access code elements need to reside on the remote server
except the *.mdb file.
3. On the remote server, permissions need be set so that anyone can have
read access to that Access database.
Are these assumptions true ?

If the assumptions are true, the local error message

Me.AuthorsTableAdapter.Fill(Me.PubsDataSet.authors)==>Could not find
installable ISAM

does not make sense to me.

TIA for any help.

Bob
