But then I am getting the errors:
但是后来我收到了错误：

"NDSClient.exe"is a const char*string on windows. If you want it to become a const TCHAR*then you need to use the TEXTmacro. Also, you can not compare strings using ==use a equivalent TCHARfunction such as _tcscmp.
"NDSClient.exe"是const char*windows 上的字符串。如果你想让它变成 aconst TCHAR*那么你需要使用TEXT宏。此外，您不能==使用等效TCHAR函数（例如_tcscmp.

Also you can use. L"some string"to make TCHAR*. But I suggest you to use std::wstring(analog of std::stringand as std::stringneeds #include <string>) instead of TCHAR*.
你也可以使用。L"some string"使 TCHAR*。但我建议您使用std::wstring（模拟std::string和根据std::string需要#include <string>）而不是 TCHAR*。
example:
例子：
#include <windows.h>
#include <string>
#include <iostream>
using namespace std;
int main()
{
wstring s = TEXT("HELLO");
wstring ss = L"HELLO";
if(s == ss)
cout << "hello" << endl;
return 0;
}
