Open an Access Database from an InfoPath form

[steve]

I have an InfoPath form that needs to update an Access database. I'm
using VB, in Visual Studio. So far i can't even open it: the
database is on my hard drive, and no password is set. The following
is the code in my onLoad event on the InfoPath form. (I've tried it w/
out the User ID and password and get the same error)
Dim strConnection As String = _
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" _
& "C:\My_Data\New Jersey Fees.mdb"
& "User ID=Admin" _
& "Password="
Dim cn As OleDbConnection = New
OleDbConnection(strConnection)
cn.Open()
Error:
System.Security.SecurityException
Request failed.
