CODE

void __fastcall TForm1::Button1Click(TObject *Sender)

{
  PrintDialog1->Options.Clear();
  PrintDialog1->Options << poPageNums << poSelection;
  PrintDialog1->FromPage = 1;
  PrintDialog1->MinPage = 1;
  PrintDialog1->ToPage = PageControl1->PageCount;
  PrintDialog1->MaxPage = PageControl1->PageCount;
  if (PrintDialog1->Execute())
  {
    int Start, Stop;
    // determine the range the user wants to print
    switch (PrintDialog1->PrintRange)
    {
      case prSelection:

        Start = PageControl1->ActivePage->PageIndex;
        Stop = Start;
        break;
      case prPageNums:
        Start = PrintDialog1->FromPage - 1;
        Stop =  PrintDialog1->ToPage - 1;
        break;
      default:  // prAllPages
        Start = PrintDialog1->MinPage - 1;
        Stop = PrintDialog1->MaxPage - 1;
        break;
    }
    // now, print the pages
    Printer()->BeginDoc();
    for (int i = Start; i <= Stop; i++)

    {
      PageControl1->Pages[i]->PaintTo(Printer()->Handle, 10, 10);
      if (i != Stop)
        Printer()->NewPage();
    }
    Printer()->EndDoc();
  }
}

thank you very much for the replay.
That code i think is for more then one pages.
For anyone who has this problem I found a tricky solve:D

if(PrintDialog1->Execute())
            {
             File1->Visible=False;
             Form20->VertScrollBar->Position=0;
             Form20->AutoScroll=false;
             Form20->BorderStyle=bsNone;
             Form20->Height=1000;
             Form20->Width=805;
             Form20->Print();
             Form20->Height=700;
             Form20->Width=805;
             Form20->BorderStyle=bsSizeable;
             Form20->AutoScroll=true;
             File1->Visible=True;
            }

What's the trick: Form20->BorderStyle=bsSizeable; (by default) dosen't let you set a hight larger then resolution (for example: if you set the resolution 1152x864,you can set to form a maxim height 864).But if BorderStyle=bsNone you can set what height you want.And this little trick isn't so visible in application:) Thank you for your support.
