Double Buffering? Win32 c++

I am trying to implement double buffering but it doesn't seem to work i.e. the graphic still flickers.

The WM_PAINT gets called everytime when the mouse moves. (WM_MOUSEMOVE)

Pasted WM_PAINT below:

case WM_PAINT:
        {
            hdc = BeginPaint(hWnd, &ps);
            // TODO: Add any drawing code here...
            RECT rect;
            GetClientRect(hWnd, &rect);
            int width=rect.right;
            int height=rect.bottom;

            HDC backbuffDC = CreateCompatibleDC(hdc);

            HBITMAP backbuffer = CreateCompatibleBitmap( hdc, width, height);

            int savedDC = SaveDC(backbuffDC);
            SelectObject( backbuffDC, backbuffer );
            HBRUSH hBrush = CreateSolidBrush(RGB(255,255,255));
            FillRect(backbuffDC,&rect,hBrush);
            DeleteObject(hBrush);


            if(fileImport)
            {
                importFile(backbuffDC);
            }

            if(renderWiredCube)
            {
                wireframeCube(backbuffDC);
            }

            if(renderColoredCube)
            {
                renderColorCube(backbuffDC);

            }

            BitBlt(hdc,0,0,width,height,backbuffDC,0,0,SRCCOPY);
            RestoreDC(backbuffDC,savedDC);

            DeleteObject(backbuffer);
            DeleteDC(backbuffDC);

            EndPaint(hWnd, &ps);
        }
