Ok, I give up. I am getting this error no matter what I try to do to
access an access database to get familer with asp.net as I can't afford
sql server to do sql testing.

I've installed MDAC 2.7 and made sure I added "aspuser" to the directory
(and all files inside) as full control (read,write,change,delete). I
erased the DSN that I setup to use ODBC to access the database and the
database itself has no username/password on it.

I found tons of information online but it all pointed to mdac 2.7 and
the username combo solution which I was well aware of from programming
in regular ASP.

An article from MS suggested making the "aspprocess" run in the system
context but I'll be dammed if I can figure out how to make that happen.
Machine.config is still a blur of mush to me at the moment.

--------------------------------

The Microsoft Jet database engine cannot open the file
'D:\Databases\aspnet.mdb'. It is already opened exclusively by another
user, or you need permission to view its data.

Source Error:

Line 17: SQLstring = "SELECT * FROM shipping_methods"
Line 18: myConnection = New
OleDBConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data
Source=D:\Databases\aspnet.mdb")
Line 19: myConnection.Open()
Line 20: myCommand = New OleDbCommand(SQLstring, myConnection)
Line 21: myReader = myCommand.ExecuteReader()

Greg,

The RTM .NET runs under a different account to the previous versions. it use to run a an
administrator, but they changed that for security reasons. it now runs under the account ASPNET.
Does that user have access to the database?

Daniel.

Greg,

What are the NTFS permissions for the file in question?
What are the NTFS permissions for the folder that the file is in (Access
needs to create and destroy it's little .ldb lockfile - if the user in
question doesn't have sufficient priveleges to the folder that could be the
problem as well).

As a suggestion (to help in seeing if this is a permissions related
problem), try giving the Everyone group Full Control to the folder (and
making sure that the permissions are propogated to files/folders)

Cheers
Ken
