2809:Printing the contents of a TMemo or TListbox

KEYWORDS: print tmemo memo tlistbox listbox lines contents AREA: VCL Programmi

Q: How can I print all of the lines within a TMemo or TListbox component?

A: The function below accepts a TStrings object as a parameter and prints
   out each string to the default printer.  Because it uses a TStrings, the
   function will work with any type of component that contains a
   TStrings-type property, such as a TDBMemo or TOutline.

{ Begin code listing }

uses Printers;

procedure PrintStrings(Strings: TStrings);
var
  Prn: TextFile;
  i: word;
begin
  AssignPrn(Prn);
  try
    Rewrite(Prn);
    try
      for i := 0 to Strings.Count - 1 do
        writeln(Prn, Strings.Strings[i]);
    finally
      CloseFile(Prn);
    end;
  except
    on EInOutError do
      MessageDlg('Error Printing text.', mtError, [mbOk], 0);
  end;
end;

{ End code listing }

To print out the contents of a TMemo or TListbox, use the following
code:

PrintStrings(Memo1.Lines);

or

PrintStrings(Listbox1.Items);
