#include <memory>       //For STL auto_ptr class

void __fastcall TForm1::Button1Click(TObject *Sender)
  String NewFileName, OldFileName;
  SavePictureDialog1->DefaultExt = GraphicExtension(__classid(Graphics::TBitmap));
  SavePictureDialog1->Filter = GraphicFilter(__classid(Graphics::TBitmap));
  OldFileName = L"../factory.bmp";
  if (SavePictureDialog1->Execute())
	NewFileName = SavePictureDialog1->FileName;
	std::auto_ptr<TFileStream> OldFile(new TFileStream(OldFileName, (fmOpenRead | fmShareDenyWrite)));
	std::auto_ptr<TFileStream> NewFile(new TFileStream(NewFileName, (fmCreate | fmShareDenyRead)));
	NewFile->CopyFrom(OldFile.get(), OldFile->Size);
