Where (and how) are you trying to use _CRT_SECURE_NO_ WARNINGS?

HANDLE WINAPI hook_CreateFileW(LPCWSTR lpFileName, DWORD dwDesiredAccess, DWORD dwShareMode, LPSECURITY_ATTRIBUTES lpSecurityAttributes, DWORD dwCreationDisposition, DWORD dwFlagsAndAttributes, HANDLE hTemplateFile)
{
	HANDLE Result;

	// Get custom file path
	wchar_t CustomFile[MAX_PATH] = L"FUUEL\\";
	wcscat(CustomFile, lpFileName);

	// See if custom file exists (By setting CreationDisposition to OPEN_EXISTING the API will only open the file if it exists)
	if (detour_CreateFileW->GetOriginalFunction()(CustomFile, dwDesiredAccess, dwShareMode, lpSecurityAttributes, OPEN_EXISTING, dwFlagsAndAttributes, hTemplateFile) != INVALID_HANDLE_VALUE)
	{
		// Our File Exists
		Result = detour_CreateFileW->GetOriginalFunction()(CustomFile, dwDesiredAccess, dwShareMode, lpSecurityAttributes, dwCreationDisposition, dwFlagsAndAttributes, hTemplateFile);
	}
	else
	{
		// Use origional File
		Result = detour_CreateFileW->GetOriginalFunction()(lpFileName, dwDesiredAccess, dwShareMode, lpSecurityAttributes, dwCreationDisposition, dwFlagsAndAttributes, hTemplateFile);
	}
	return Result;
}

ERROR :

error C4996: 'wcscat': This function or variable may be unsafe. Consider using wcscat_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.

I would recommend you use wcscat_s as the warning recommends.

wcscat_s(CustomFile, MAX_PATH, lpFileName);

Otherwise, you need to define _CRT_SECURE_NO_ WARNINGS. You can do this by right clicking on your project and select Properties->C++->Preprocessor and add it to the definitions.

I did but its giving an error again

like this :

error D8021: invalid numeric argument '/wd_CRT_SECURE_NO_WARNINGS'

How are you defining _CRT_SECURE_NO_ WARNINGS? Make sure it is not defined anywhere in your code, then go to Project Properties -> Configuration Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions and add _CRT_SECURE_NO_ WARNINGS. Then go to Project Properties -> Configuration Properties -> C/C++ -> Command Line and look at in the All Options box and see what is there. Among the options you should see /D "_CRT_SECURE_NO _WARNINGS". You should not see /wd_CRT_SECURE_N O_WARNINGS. The correct /wd option to disable this warning would be /wd4996. If everything looks OK on the project properties, right click on the source file itself and check the command line options the same way.
