Rodolfo,
I emulate the up/down pointer in the column with a Label object that uses two characters out of the Wingding font. The Label class has a method to keep it positioned to the left of the right edge of the column.
>Yes, I did. But what I really need is something like the outlook , which show
>the order of the column. Also I need that take care about the lenght of the caption's name (of the head) because in my software the user can change it.
