上面1、2、3 类宏通常和条件编译预处理指令 #if/#ifdef/#ifndef 配合使用 辅助类^ __VA_ARGS__: 在函数式宏中,代表变长部分参数 (...),参考 MSDN:Variadic Macros __COUNTER__: include 展开编译单元后,编译时第一次遇到 __COUNTER__ 替换为 0,以后在这个编译每遇到一次 __COUNTER__ 自增一。不同...
在#define WINVER 0x0500的时候,菜单显示一切正常 后来因为其他程序需要,改成#define WINVER 0x0501,结果菜单里面的图标就没了,菜单的背景也都变成了系统的灰色 经过痛苦的查找,终于在atlctrlw.h里面找到一点线索 // Define _WTL_CMDBAR_VISTA_MENUS as 0 to exclude Vista menus support #if !defined(_WTL_CMD...
