Question

Original connectionstring whitch working on MSSQL 2000:

Provider=SQLOLEDB.1; Persist Security Info=True; User ID=XXXXXXXX; Initial Catalog=IntranetApps; Data Source=MS; Use Procedure for Prepare=1; Auto Translate=True; Packet Size=4096; Workstation ID=datawriter; Password=XXXXXXXX’;

New connectionstring which not working on MSSQL 2008:

Provider=SQLNCLI10;Server=PR-NB-CIS011\SQLEXPRESS;Database=IntranetApps;Uid=XXXXXXXX;Pwd=XXXXXXXX;

I tryed change provider to SQLNCLI10.1, without provider, …

Once in past i solved same problem, but hell, i don’t remember it now. I thing that there was needed install some provider, but i can find nothing about it now.

There is code witch throw exception:

this.connection = new ActiveXObject("ADODB.Connection");
    this.connection.ConnectionString = this.conString;
    try {
        this.connection.Open;
    }
    catch(e){
        Response.write("Chyba pri pripojeni na db.");
        return false; // pokud dojde k chybe pri pripojovani k databazi, pak fce vraci false, jinak true
    }

If this really is a connection string problem, you should:

1. study the basics
2. create a zero length “whatever.udl” file and start it from command line; you can then twiddle the parameters, test the connection, and paste the connection string from the clipboard
3. try ";Data Source=PR-NB-CIS011\SQLEXPRESS;" instead of ";Server=PR-NB-CIS011\SQLEXPRESS;"
