Question

I have a memo object in my report, and a need replace “%…%” strings. For example, in Rave Report:

MemoBuf.ReplaceAll('%my_str%',  "new string", false);

But, don’t exists a method (or property) to replace text, in the FastReport. How I can do this?

I’m using Fast Report 4.9.72 and Delphi 2010.

Thanks!

Since there is no StringReplace in FastReport available I would do it from the Delphi code. It is possible to import functions somehow but this seems to me better arranged. Please note, that in this first example I suppose that the Memo1 exists (you would get an access violation otherwise).

procedure TForm1.Button1Click(Sender: TObject);
var
  Memo: TfrxMemoView;
begin
  Memo := frxReport1.FindObject('Memo1') as TfrxMemoView;
  Memo.Text := StringReplace(Memo.Text, '%my_str%', 'new string', [rfReplaceAll]);
  frxReport1.ShowReport;
end;

If you are not sure about component name or type you should use something like this:

procedure TForm1.Button2Click(Sender: TObject);
var
  Memo: TfrxMemoView;
  Component: TfrxComponent;
begin
  Component := frxReport1.FindObject('Memo1');
  if Component is TfrxMemoView then
  begin
    Memo := Component as TfrxMemoView;
    Memo.Text := StringReplace(Memo.Text, '%my_str%', 'new string', [rfReplaceAll]);
    frxReport1.ShowReport;
  end;
end;
