Rex,

I don't think I'd do it this way to begin with ... I'd have two different DataAccess objects, one to get data from Oracle, one from OleDB.

However, to do what you want to do, if you can cast OracleConnection to OleDbConnection (and I'm not sure if you can or not), then you could maybe do something like this (this is untested code, and it's also C# code ... sorry, I don't know VB well enough):
OleDbConnection ConPubs;
if (strProvider == "OracleClient")
{
  OracleConnection o = new OracleConnection(odh);
  ConPubs = o;
}
else
  ConPubs = new OleDbConnection(odh);

ConPubs.Open();
