well we were all n0obsat some point in time. No problem in asking. Here is a simple function which does exactly this :
好吧，我们在某个时间点都是n0obs。问没有问题。这是一个简单的函数，它正是这样做的：
#include <windows.h>
#include <string>
bool dirExists(const std::string& dirName_in)
{
DWORD ftyp = GetFileAttributesA(dirName_in.c_str());
if (ftyp == INVALID_FILE_ATTRIBUTES)
return false; //something is wrong with your path!
if (ftyp & FILE_ATTRIBUTE_DIRECTORY)
return true; // this is a directory!
return false; // this is not a directory!
}

If linking to the shell Lightweight API (shlwapi.dll) is ok for you, you can use the PathIsDirectory function
如果链接到外壳轻量级 API (shlwapi.dll) 对您来说没问题，您可以使用PathIsDirectory 函数

This code might work:
此代码可能有效：
//if the directory exists
DWORD dwAttr = GetFileAttributes(str);
if(dwAttr != 0xffffffff && (dwAttr & FILE_ATTRIBUTE_DIRECTORY))
