The provider could not determine the string value, For example, the row was just created.. Ole

Question

 public void SetConnection(string text1, string text2, string text3, string text4, string text5, string text6, string text7)
    {
        string connectionString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source= c:\\Users\\Clients Information pats.mdb";


        database = new OleDbConnection(connectionString);
        database.Open();

    }

data1 = DataAccess.DatabaseTables("SELECT * from [CLIENTS]", DataAccess.database);

 public DataTable DatabaseTables(string QueryString, OleDbConnection DataConnection)
    {

        OleDbCommand SQLQuery = new OleDbCommand();
        DataTable data = null;
        SQLQuery.Connection = null;
        OleDbDataAdapter dataAdapter = null;
        SQLQuery.CommandText = QueryString;
        SQLQuery.Connection = DataConnection;
        data = new DataTable();
        dataAdapter = new OleDbDataAdapter(SQLQuery);

        dataAdapter.Fill(data);
        return data;
    }

Getting a strange error as listed in the heading. Setconnection sets up my connection string and connection ok. Then 'data1' calls the function DatabaseTables which calls an exception at 'dataAdapter.Fill(data);'. I think the issue could be my access on my machine. The mdb will not open in 2013 on my machine because it is an earlier version. I installed access 2007 runtime. Opened it and it said it was read only that i need to change this attribute. Then i tried to open access 2013 as administrator, office 2013 did some reconfig by itself and now this mdb file always tries to open in access 2013. I will now try to reinstall access 2007. Is it possible i need to uninstall access 2013 or is this maybe not a access issue at all but maybe an issue with my code or the mdb itself. I copied this mdb file from a server where it opened on access 2007 on that machine but it tried to enhance it because it is apparently an even earlier version

Answer 1

"Provider=Microsoft.ACE.OLEDB.12.0;Data Source= u:\\Clients Information pats_30may13.accdb;Jet OLEDB:Database Password=MyDbPassword;";

I upgraded the source access database to accdb format plus made sure i could open this database on my own computer as opposed to the server. I got a notification that there were some errors with the upgrade but it appeared ok. Then i used the above connection string which solved the issue.
