Question

I’m trying to connect to the database, and it keeps telling me “invalid instance”.

Here’s my code:

string connectionString = "Driver={SQL Server};Server=server;Database=db;;Uid=user;Pwd=pass;";
OdbcConnection MyConnection = new OdbcConnection();
MyConnection.ConnectionString = connectionString;
MyConnection.Open();

What is the problem?

Thanks!

Try using this.

Data Source=myServerAddress;Initial Catalog=myDataBase;User Id=myUsername;Password=myPassword;

And if you are using MS Sql server, better use with SqlConnection.

using(SqlConnection conn = new SqlConnection(connestionString)){
   conn.open();
   ..
}
