Changing memo's value before print

Hi!

I'd like to print on matrix printer, but i have to change some special hungarian characters after loading from database but, before printed on the dot printer to make readable my printed data.

I did the following:

function Csere (Mit : string) : String;
var I : integer;
begin
for I := 1 to length(Mit) do
case Mit of
'Ő' : Mit := 'ő';
'Ű' : Mit := 'ű';
end;
Result := Mit;
end;

procedure Memo1OnBeforePrint(Sender: TfrxComponent);
begin
Memo1.Memo.Text := Csere(Memo1.Memo.Text);
end;


It's not working....

I try to place the call of 'Csere' function in Master data onBeforePrint event, but it isn't working too.

if I say in 'Csere' function Result := 'A', then it's working, I see the 'A' characters on the preview.

but if I say Result := IntToStr(Length(Mit)); then I see a wrong number (and same in all lines), for example 65, however the length of data is differnet in each line(from 1 to 10 chars).

It looks like when the onbeforeprint event is running not the correct data is in the Memo1.Memo.Text;

How can I solve this problem?

Thanks!

    Memo1.Memo.Text := Csere(Memo1.Memo.Text); - it is wrong call, you need try - Memo1.Text := Csere(Memo1.Text);

    My function:

    function Convert(Str:String):String;
    var i:integer;
    begin
    for i:=0 to length(Str)-1 do
    case Str of
    'a': Str:= 'A';
    'f': Str:= 'F';
    end;
    Result := Str;
    end;

    procedure Memo2OnBeforePrint(Sender: TfrxComponent);
    begin
    Memo2.Text:= Convert(Memo2.text);

    end;
    It is work!

    Den! Tanks!

    How do you test it? With a 'fix' text in the memo1 or data from dataset?
    I realised something. When I used 'fix' text for example: I hope this will be ok! then the function change the letters well, but when I'd like to read this text from database (firebird) memo1.text contains the 'dataset_name."field_name"' string, not the data from dataset, so I can't change anything....

    How can I catch that time when the finally text is in the memo.text? Not in onbeforeprint event???

    I found the solution.

    OnAfterData event.

    but why? ;)

    Thank you Den, it works!

    ;)

    >>but why?

    In the help about OnAfterData event:
    "The name of the script routine that will be called after the object gets data."

    In the help about OnBeforePrint event:
    "The name of the script routine that will be called before the object is handled."
