What steps will reproduce the problem?
1. CEdiUI获得焦点并可用 UIEVENT_SETFOCUS && 
IsEnabled()调用CEditWnd的Init
2. Init中调用Create创建窗体
3. Create中调用RegisterWindowClass注册窗体样式，wc.hbrBackground = 
(HBRUSH)GetStockObject(BLACK_BRUSH);不起作用，无法修改背景颜色！

What is the expected output? What do you see instead?
修改成和focusedimage图片一样的背景颜色；但是依然是白色！
