For Standard Security:
oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _
"Dbq=c:\somepath\mydb.mdb;"
If you are using a Workgroup (System database):
oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _
"Dbq=c:\somepath\mydb.mdb;" & _
"SystemDB=c:\somepath\mydb.mdw;", _
"myUsername", "myPassword"
If want to open up the MDB exclusively
oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _
"Dbq=c:\somepath\mydb.mdb;" & _
"Exclusive=1;"
If MDB is located on a Network Share
oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _
"Dbq=\\myServer\myShare\myPath\myDb.mdb;"
If MDB is located on a remote machine
- Call an XML Web Service that contains data access web methods for MDB
- Or upgrade to SQL Server and use an IP connection string
If you don't know the path to the MDB (using ASP)
<% ' ASP server-side code
oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _
"Dbq=" & Server.MapPath(".") & "\db\myDb.mdb;"
%>
Make sure the Web identity has read/write permissions to the directory
the MDB is located in. e.g. "db" would need the read/write permissions.
If you don't know the path to the MDB (using VB)
oConn.Open "Driver={Microsoft Access Driver (*.mdb)};" & _
"Dbq=" & App.Path & "\myDb.mdb;" This assumes the MDB is in the same directory where the application is running.
