Newline Inside a String To Be Shown At a TMemoBox

Question

I'm building a String called FullMemo, that would be displayed at a TMemoBox, but the problem is that I'm trying to make newlines like this:

FullMemo := txtFistMemo.Text + '\n' + txtDetails.Text

What I got is the content of txtFirstMemo the character \n, not a newline, and the content of txtDetails. What I should do to make the newline work?

Answer 1

The solution is to use #13#10 or better as Sertac suggested sLineBreak.

FullMemo := txtFistMemo.Text + #13#10 + txtDetails.Text;
FullMemo := txtFistMemo.Text + sLineBreak + txtDetails.Text;

Answer 2

A more platform independent solution would be TStringList.

var
  Strings: TStrings;
begin
  Strings := TStringList.Create;
  try
    Strings.Assign(txtFirstMemo.Lines); // Assuming you use a TMemo
    Strings.AddStrings(txtDetails.Lines);
    FullMemo := Strings.Text;
  finally
    Strings.Free;
  end;
end;

To Add an empty newline you can use:

Strings.Add('');

Answer 3

Use

FullMemo := txtFistMemo.Text + #13#10 + txtDetails.Text

Answer 4

You don't make newlines like this, you use symbol #13:

FullMemo := txtFistMemo.Text + #13 + txtDetails.Text
    + Chr(13) + 'some more text'#13.

#13 is CR, #10 is LF, sometimes it's enough to use just CR, sometimes (when writing text files for instance) use #13#10.

Answer 5

You can declare something like this:

const 
 CRLF = #13#10;
 LBRK = CRLF+ CRLF;

in a common unit and use it in all your programs. It will be really handy.
