connectionString = @"server=localhost;database=" + lbDatabase.SelectedItem.ToString() + ";userid=root;password=;";
string query = "SELECT order_id FROM orders WHERE id = 1";
MySqlConnection connect = new MySqlConnection(connectionString);
MySqlCommand cmd = new MySqlCommand(query, connect);
reader = cmd.ExecuteReader();
Hello,
I have this problem when I run the following code. I get this not so very specific error:
An unhandled exception of type 'System.InvalidOperationException'
occurred in MySql.Data.dll
Additional information: Connection must be valid and open.
If anyone could help me out I would really appreciate it,
Thank you.
