reduce nictitate gdi+ c++

i'm controlling gdi+ c++/mfc concentration i only can't seem prevaricate flickering whenever window resized.

i have already attempted steps:

• returned loyal onerasebkgnd();


• returned zero onctlcolor();


• used double buffering according code:

void vwview::ondraw(cdc* pdc) 
{
   crect rcclient;
   getclientrect(rcclient);

   bitmap bmp(rcclient.width(), rcclient.height());
   graphics graphics(&bmp);

   graphics.drawimage(m_image, rcclient.left, rcclient.top);

   graphics grph(pdc->m_hdc);
   grph.drawimage(&bmp, 0, 0);
}

am i doing something wrong? there another proceed grasp this?
