This compiled but gave me this error when i executed the select:

System.NullReferenceException: Object reference not set to an instance of an object.
   at Sistema.frmLogin.btnOk_Click(Object sender, EventArgs e) in D:\Documents and Settings\suporte\Meus documentos\Visual Studio 2005\Projects\SGC\Sistema de Gestão Comercial\frmLogin.cs:line 30

oh god.. why this have to be so complicated?

here is my code:

            FbCommand cmd = new FbCommand("SELECT CLI_COD FROM CLIENTES WHERE CLI_NOME='" + txtUsuario.ToString() + "'", cn);
            try {
                int i = (int) cmd.ExecuteScalar();
            } catch (Exception ex) {
                MessageBox.Show(ex.ToString());
            }
