template<typename T, typename… U> array(T, U…) -> array<enable_if_t<(is_same_v<T, U> && …), T>, (1 + sizeof…(U))>;} 五、基础技巧 5.1 typename 关键字 1.c++规定模板中通过域作用符访问的嵌套从属名称不是类型名称,为了表明该名称是类型,需要加上 typename 关键字。

If you enable this option, you must set TDF_SHOW_PROGRESS_BAR to have the expected behavior. TDF_CALLBACK_TIMER Indicates that the CTaskDialog callback interval is set to approximately 200 milliseconds. TDF_POSITION_RELATIVE_TO_WINDOW Configures the CTaskDialog to be centered relative to the ...
