    <p>I want to connect to mysql server from C#. I found some code on the net but somewhere there is something wrong because i get </p> <blockquote> <p>A first chance exception of type 'System.ArgumentException' occurred in System.Data.dll</p> </blockquote> <p>error.</p> <pre><code>private void Initialise() { server = "dns to server"; database = "db_name"; uid = "root"; password = "password"; string connectionString; connectionString = "SERVER=" + server + ";" + "DATABASE=" + database + ";" + "UID=" + uid + ";" + "PASSWORD=" + password + ";"; OR connectionString = "Server=xxx.no-ip.org;Database=rdb;"+ "Uid=root;Pwd=wHt2%Zt;"; connection = new MySqlConnection(connectionString); if (this.OpenConnection() == true) Console.Out.Write("SUCCESS"); else Console.Out.Write("ERROR"); } private bool OpenConnection() { try { connection.Open(); return true; } catch (MySqlException ex){ switch (ex.Number) { case 0: MessageBox.Show("Cannot connect to server. Contact administrator"); break; case 1045: MessageBox.Show("Invalid username/password, please try again"); break; } return false; } } </code></pre> <p>I don't get any message on the console.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
