Add lines in a certain place of Tmemo

Question

I have some variables that receive some data from a common DIT. My doubt is the following, the person will click the button and Tmemo will receive the data, I would like in this action it cleaned the same Dit and repeat the process as often as necessary, but I need to insert this data in the middle of the Tmemo, as the example below:

    Memo1.Lines.Add(var1); #linha adicionada ao clicar no botão.
    Memo1.Lines.Add('linha adicionada'); # essa linha deve ser adicionada após a
    anterior quando o usuário clicar no mesmo botão.
    Memo1.Lines.Add('linha adicionada2');

Answer 1

You can use the following command to write on a certain line of the TMemo:

Memo1.Lines[3] := 'asd';

Or you can do so too:

Memo1.Lines.Insert(3, 'asd');

If you need to delete a specific line use:

Memo1.Lines.Delete(3);
