  A report design consists of a heirachal structure of objects.
  page, objects on page "bands or other objects", objects within objects on the page "memoviews in bands". Meaurements like "top", are relative to the object's parent object and not necessarily related to where they are located on the output page.
  What are you really trying to accomplish?

  A would like to make report for printing to forms. And many printers printing from other offset (Top and Left). And I need to develop setting of this ofset for different printers.
  
  one printer printing to form right, but other printer printing 5mm down from top. I want to set in my application this difference.
  
  I know how to do it like this example:
  ((TfrxMemoView*)frxReport1->FindObject("MemoTo1"))->Top+=0.5;
  ((TfrxMemoView*)frxReport1->FindObject("MemoTo2"))->Top+=0.5;
  ...
  ((TfrxMemoView*)frxReport1->FindObject("MemoTox"))->Top+=0.5;
  
  But by me it is not good way to set direct to all components.
  I would like to do it by cycle, but I do not know how?
  Please help.

  here is a short sample
  procedure TForm1.Button1Click(Sender: TObject);
  var
  //declare var of types needed
  ob:tobject;
  bnd:Tfrxpageheader;
  i,b1,c1:integer;
  obname:string;
  pg:tfrxReportpage;
  begin
  frxreport1.LoadFromFile(wpath+'2.fr3');
  for i := 0 to frxreport1.Objects.Count-1 do
  begin
  ob:=frxreport1.Objects; // find the page
  if ob.ClassName = 'TfrxReportPage' then
  Pg := frxReport1.Pages as TfrxReportPage;
  // find a band
  if pg.FindBand(TfrxPageHeader)<> nil then
  begin
  bnd := pg.FindBand(TfrxPageHeader)as tfrxpageheader;
  // iterate band objects here in the same manner
  
  end
  else
  begin
  // add band and memo here since band did not exist
  end;
  end;
  frxreport1.ShowReport;
  end;
  
  generally to shift all objects down or left by the same amount it is usually sufficient to just alter the page's
  top and left margin settings.

  It does not work.
  
  But I tryed this:
  void __fastcall TFormMain::frxReport1BeforePrint(TfrxReportComponent *c)
  {
  TfrxMemoView* mv;
  AnsiString s=c->ClassName();
  if(s=="TfrxMemoView")
  {
  mv=(TfrxMemoView*)c;
  mv->Top=mv->Top+(StrToFloat(EditTop->Text)/10);
  mv->Left=mv->Left+(StrToFloat(EditLeft->Text)/10);
  }
  }
  
  and it is also does not work. Please Help how to do it.

  I also tried this function:
  
  bool TFormMain::Move(int x, int y)
  {
  for (int i=0;frxReport1->Objects->Count-1;i++)
  {
  if (frxReport1->Objects.ClassNameIs("TfrxMemoView"))
  {
  ((TfrxMemoView*)frxReport1->FindObject(frxReport1->Objects))->Top+=y; // error
  ((TfrxMemoView*)frxReport1->FindObject(frxReport1->Objects))->Left+=x; //error
  }
  }
  return true;
  }
  
  but with error:
  [C++ Error] E2034 Cannot convert 'TList' to 'AnsiString'
  
  Please help!!!

  TfrxMemoView * Memo = NULL;
  
     for(int idx = 0;idx < frxReport1->Pages[0]->AllObjects->Count;idx ++)
       if (Memo = dynamic_cast <TfrxMemoView *> ((TObject *)frxReport1->Pages[0]->AllObjects->Items[idx]))
       {
         Memo->Top = 100;
       }
