std::tuple可看做std::pair的泛化实现，std::pair包含两个元素，std::tuple 可以同时包含多个元素，...
std::string是C++标准库中的一个字符串类,用于表示可变长度的字符序列。而LPOLESTR是一个指向OLE字符串的指针,即一个Unicode字符串。 在进行字符串转换时,需要注意编码的差异。std::string是使用字符数组表示的ANSI或UTF-8编码的字符串,而LPOLESTR是UTF-16编码的字符串。因此,在将std::string转换为LPOLESTR时,需要...

如果你需要在多个线程中设置不同的值,可以考虑使用std::async或其他线程管理工具来创建多个任务,并为每个任务分配一个独立的std::promise对象。 如果你需要在单个std::promise对象中处理多个值,可以考虑使用更复杂的数据结构(如std::vector、std::tuple等)来封装这些值,并在set_value时一次性设置整个数据结构。set...
