error C2446: == : no conversion from const char * to TCHAR *

Question

I have a TCHAR define below:

 TCHAR szProcessName[MAX_PATH] = TEXT("<unknown>");

and I want to comapare as below:

if(szProcessName == "NDSClient.exe")
{
} 

But then I am getting the errors:

error C2446: == : no conversion from const char * to TCHAR *
error C2440: '==' : cannot convert from 'const char [14]' to 'TCHAR [260]'

Answer 1

"NDSClient.exe" is a const char* string on windows. If you want it to become a const TCHAR* then you need to use the TEXT macro. Also, you can not compare strings using == use a equivalent TCHAR function such as _tcscmp.

Answer 2

Also you can use. L"some string" to make TCHAR*. But I suggest you to use std::wstring (analog of std::string and as std::string needs #include <string>) instead of TCHAR*.

example:

#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;
}
