Sorry, I've made a typing mistake again. It should:
case WM_PAINT:
    hdc = BeginPaint(hwnd, &ps);
    hBrushOld = SelectObject(hdc, hBrush);
    GetClientRect(&rect);
    Rectangle(hdc, 10, 20, 30, 40);
    SelectObject(hdc, hBrushOld); //1
    EndPaint(hwnd, &ps);
break;
(But appearently  you understood what I meant)

I'm not using common controls currently.

Anyway, should I use a ReleaseDC() or something after
"hdc = reinterpret_cast<HDC>(wParam);" ?
