关于windows C程序设计的疑问，很急的问？

[oxygenlee]

在定义和注册窗口类的函数中要定义WNDCLASS,如：
WNDCLASS wc;
...
wc.hbrBackground = GetStockObject(WHITE_BRUSH);
...
return (RegisterClass (&wcSimpwin));

但build后报错为cannot convert from 'void *' to 'struct HBRUSH__ *'
Conversion from 'void*' to pointer to non-'void'
requires an explicit cast

不知为什么，几本书上都是这么定义的呀，怎么会有错呢，哪位大虾请赐教，谢谢了！！

wc.hbrBackground = GetStockObject(WHITE_BRUSH);
改为wc.hbrBackground = （struct HBRUSH__ *）GetStockObject(WHITE_BRUSH);
