Some help on using ODBC DSN and MS access

Hi everybody,

Im trying to access a Ms Access database outside my root website
folder, so Im using ODBC DSN. I have already the DSN create and
working (this same DSN is used by many classic ASP websites I have
running on my remote server). Im also have latest ODBC and JET
drivers
installed.


My code is something like this:


Dim objConn As New OdbcConnection
objConn.ConnectionString = "DSN=MyDSN;"


objConn.Open()


Const strSQL As String = "SELECT * FROM customers"
Dim objCmd As New OdbcCommand(strSQL, objConn)


However when I try to run this I always get the error "ERROR [IM002]
[Microsoft][ODBC Driver Manager] Data source name not found and no
default driver specified" on the line that opens the connection ->
objConn.Open()


Any sugestion why is this happening? Or perhaps some turnaround on
how
to access a MS Access database that is outside my root webfolder.


Any help is higly appreciated


Thanks in advance


Joao

What happens if you use a DSN-less connection (with Jet OLEDB) instead of a DSN (and ODBC)? Jet
OLEDB is the preferred method as it provides better feature support and is the more stable
technology.
