Question

#include <windows.h>
#include <iostream>
using namespace std;
int main() {
char* file="d:/tester";
WIN32_FIND_DATA FindFileData;
    HANDLE hFind;
hFind = FindFirstFile(file, &FindFileData);  // line of error says argument of type char* is incompatible with parameter of type LPCWSTR
}

I can’t understand the error.What is it and how can I solve the error?

I am making a console app and need to check if files are in there in the directory .

Answer 1

You are calling function that expects wide character string (FindFirstFileW). You either change file to use wchar_t* file = L"d:\\tester"; or use an ASCII version of the function FindFirstFileA.
