i write following code in wm_paint


Bitmap b(800,800);
HDC hdc;
hdc = BeginPaint(g_hDialogWindow, &ps);
Graphics graphics(g_hDialogWindow);
Graphics *graphics2=Graphics::FromImage(&b);

Pen pen(Color(255, 40,40,40),2);
graphics.DrawLine(&pen,0,0,600,600);
graphics2->DrawLine(&pen,0,0,400,400);

b.GetHBITMAP(Color(255,255,255),&dcimage);



BITMAP bm;
HDC hdcMem = CreateCompatibleDC(hdc);
SelectObject(hdcMem, dcimage);
GetObject(dcimage, sizeof(bm), &bm);

BitBlt(hdc,rect.left, rect.top, bm.bmWidth, bm.bmHeight, hdcMem, 0, 0, SRCCOPY);
DeleteDC(hdcMem);

EndPaint(g_hDialogWindow, &ps);

it is creating bitmap image but its background is blue instead of white, i used b.GetHBITMAP(Color(255,255,255),&dcimage);

plz tell me what wrong with this code
