Add a text at a certain position

Question

Hello, I need to add a TEXT at a certain position of a TXT file, if possible using STRING LIST.

I have a TXT and inside this TXT has about 300 lines. And in the middle of it has the following line:

hardware{98828};

I need to add a TEXT before that sentence there, how can I do ? in case it has to identify that there is this TEXT in the TXT file, and add a word before it.

I look forward to any help!

You can read the file line by line and save in a Stringlist, as you commented and go checking if there is this "string" in this line with Pos(), for example:

int posicao = Pos(textoDesejado, linha);

if(posicao > 0) { } // encontrou o textoDesejado...

if you find it is possible to edit the text using Copy(), for example:

linha = Copy(linha, 1, posicao) + outroTextoAdicionado + Copy(linha, posicao + 1, Length(linha));

And after putting the line in Stringlist... And so on until you finish reading the entire txt file.
