Question

I try to connect to informix server 11.5 using using IBM.Data.Informix (located in C:\Program Files\IBM\IBM DATA SERVER DRIVER\bin\netf20_32\IBM.Data.Informix.dll). I’m using vb2008 and when I try to connect throws an error invalid argument.

Where is the problem? Thanks

    public static IfxConnection MAkeConnInformix()
    {
        IfxConnection cnn = new IfxConnection();
        string error = "";
        try
        {
            string ConnectionString = Database=mydbname;Host=10.8.8.50;Server=mainserver_net;Service=1526; Protocol=onsoctcp;UID=myuser;Password=mypass";
            cnn.ConnectionString = ConnectionString;
        }
        catch (Exception ex)
        {
            error = ex.Message;
        }
        return cnn;
    }

If you cannot connect because something is wrong with locale then add properties to your connect string. I do not use .net, but in JDBC such Informix connect string with Polish locale info looks like:

jdbc:informix-sqli://127.0.0.1:9088/test_db:informixserver=ol_local;DB_LOCALE=pl_PL.CP1250;CLIENT_LOCALE=pl_PL.CP1250;charSet=CP1250

In Listing 1 on http://www.ibm.com/developerworks/data/library/techarticle/dm-0510durity/ there is example that says that DB_LOCALE and others can be add to .net connet string/
