Good morning Marcelo Okada. Face with the 7 I "think" that you can’t do anything DIRECT with the component. But you can do a GAMBIARRA with SQL. See the Example I give you with the city table.
id_cidade int, cidade_nome varcha(50)
In the city table I have the following cities
Rio de janeiro
São Paulo
Cidade A
Cidade B
Then I would make the following SQL to add the word ALL in the CITY TABLE and may appear in Dblukupcombobox.. Still Showing Word All As First OPTION in List.
select id_cidade, cidade_nome, 1 as ordem from cidade
union all
select -1,'TODAS' , 0 as ordem
order by 3,2
I hope I understood your need and was able to express myself clearly.
Any doubt about my example is just talk.
hello good morning, So what would be the best program to make these software, which version of Delphi is better, or there is another?
– Marcelo Okada
Good evening. Any program you know how to use is good.. If you use a program you don’t know it will be harder to develop with it. I really like Delphi 7 and Tokyo. But I also use JAVA and PHP. There’s a vast world to choose from. The business is to select one and DROP YOUR DICK on it :). It has taste for everything.. This is mine.
