Ok, I figured out how to get the value back from a VFP stored procedure.
    protected Int32 VFPGetNextID(String tablename)
    {
        String strCmd = "GetNextID('" + tablename.Trim().ToUpper() + "')";
        Int32 retval = 0;
        OleDbConnection myconn = new OleDbConnection(@"Provider=VFPOLEDB.1;Data Source=\\path\dbccontainer.DBC");
        myconn.Open();
        OleDbCommand cmd = new OleDbCommand(strCmd, myconn);
        OleDbDataReader reader = cmd.ExecuteReader();
        if (reader.Read())
        {
            retval = System.Convert.ToInt32(reader.GetValue(0));
        }
        reader.Close();
        myconn.Close();
       
        return retval;
    }
Thanks for the help! One more roadblock down!
