It depends on what TCHARis. If you compile with Unicode enabled, TCHARis defined as wchar_t. Then you can use std::wcout, for example:
这取决于是什么TCHAR。如果在启用 Unicode 的情况下编译，TCHAR则定义为wchar_t. 然后你可以使用std::wcout，例如：
std::wcout << L"Error: " << errmsg << '\n';
If Unicode is not enabled, TCHARis an ordinary charand you can use the ordinary std::cout:
如果未启用 Unicode，TCHAR则是普通的char，您可以使用普通的std::cout：
std::cout << "Error: " << errmsg << '\n';

A Google search revealed this discussionwhich essentially recommends tprintf.

#include <tchar.h> /* _tprintf */
DWORD dwError;
BOOL fOk;
HLOCAL hlocal = NULL; // Buffer that gets the error message string
fOk = FormatMessage(
FORMAT_MESSAGE_FROM_SYSTEM |
FORMAT_MESSAGE_IGNORE_INSERTS |
FORMAT_MESSAGE_ALLOCATE_BUFFER,
NULL, dwError, 0, (PTSTR) &hlocal, 0, NULL);
if (! fOk) hlocal = TEXT("Fehler FormatMessage");
_tprintf( TEXT("%d\t%s\n"), dwError, hlocal );
if (fOk) LocalFree(hlocal);

I really don't know why but this code worked for me:
我真的不知道为什么，但这段代码对我有用：
TCHAR NPath[MAX_PATH];
DWORD a = GetCurrentDirectory(MAX_PATH, NPath);
string b = "";
for(int i=0; i<a;i++){
b+=NPath[i];
}
cout << b;
system("pause");
Sorry but i can't really explain why it works and don't have time to search it now. Later!
抱歉，我无法真正解释它为什么有效，现在也没有时间搜索它。之后！
