Dude I believe the mistake is on the Lina

strSql = "insert into ClientesAuE (nome, telefone, celular,email,endereco,numero,cidade,sexo) values (nome@, telefone@, celular@,email@,endereco@,numero@,cidade@,sexo@)";

I believe you should put the values in the following way @name, @phone... with @beforethe name
