我知道有一个函数 SHGetSpecialFolderPath 但它检索BOOL
，我想获取路径作为字符串。

I know there is the function SHGetSpecialFolderPath but it retrieves a BOOL and i want to get the path as a string.

可以帮助一些吗？

推荐答案

SHGetSpecialFolderPath（） ，命名为 lpszPath ，标记为 __ out 。

应该这样做：

// Beware, brain-compiled code ahead!
wchar_t buffer[MAX_PATH];
BOOL result = SHGetSpecialFolderPath( hWnd
                                    , buffer
                                    , CSIDL_LOCAL_APPDATA
                                    , false );
if(!result) throw "You'll need error handling here!";
std::wcout << buffer;

注意：我几年来没有做过任何Win API工作。很可能有人来很快地指出我在哪里吹。

Note: I haven't done any Win API work in years. Very likely someone comes along shortly pointing out where I blew it.
