{$R *.dfm}

procedure Tf_Coba.BitBtn1Click(Sender: TObject);
var jawab:byte;

7 : MessageDlg('Tidak', mtWarning, [mbOK], 0);
end;
end;

procedure Tf_Coba.BitBtn2Click(Sender: TObject);
var jawab:byte;
begin
jawab:=PesanOn1('','',10);

begin
f_pesan:=Tf_pesan.create(nil);
f_pesan.title.Caption:=title;

f_pesan.txt.Caption:=msg;
f_pesan.ShowModal;

f_pesan.Free;
end;

Function PesanOn1(title,msg:string;sizefont:byte):TModalResult;
begin
f_dialog1:=Tf_dialog1.create(nil);
f_dialog1.ShowModal;
