title: Insert Firebird Database C#
body: <pre><code>FbCommand fbCmm = 
        new FbCommand("INSERT INTO PRODUTO
                     (CODIGO,EAN,DESCRICAO,VAL_PRODUTO,VAL_CUSTO,CAT_PRECO)" 
                     + "Values (@txt_codigo.Text, @txt_ean, @txt_descricao,
                     @txt_valPro, @txt_valCus, @txt_catPre)", ConexaoFirebird.Conexao);
  </code></pre>

  <p>What's wrong with that sentence? 
  I did a open connection in other class - <code>ConexaoFirebird.Conexao();</code></p>
