Oop! :-p
I know that what wrong is me. ha ha
this right

      long cbBuffer = 320*240*3;
      HRESULT hr = NULL;
      byte *pBuffer = (byte*)malloc(cbBuffer);

      AM_MEDIA_TYPE mt;
      BITMAPINFO  BmpInfo;
      HBITMAP hBitmap = NULL;

      hr = vcap.pGrabber->GetConnectedMediaType(&mt);
      if FAILED(hr) return;
      VIDEOINFOHEADER *pVideoHeader = (VIDEOINFOHEADER*)mt.pbFormat;
      CopyMemory(&BmpInfo.bmiHeader, &pVideoHeader->bmiHeader,
sizeof(BITMAPINFOHEADER));
      hBitmap = CreateDIBSection(0, &BmpInfo, DIB_RGB_COLORS,
(void**)&pBuffer, NULL, 0);
      hr = vcap.pGrabber->GetCurrentBuffer(&cbBuffer, (long*)pBuffer);
      if(FAILED(hr)) {
        return;
      }
      Graphics::TBitmap *bmp = new Graphics::TBitmap();
      bmp->Handle = hBitmap;
      bmp->SaveToFile("c:\\test" + (AnsiString)aa + ".bmp");
      Image1->Canvas->Draw(0,0,bmp);
      delete bmp;
      DeleteObject(hBitmap);
