C++ Qualified name is not allowed in member declaration

Question

I am following one of Fleeps old tutorials from 2012. I have encountered a speedbump, this error: qualified name is not allowed in member declaration. I have tried changing the SDK, defining/declaring the class in the main.cpp file. None of this worked. This is my header file i am encountering the error in.

#pragma once

#include <Windows.h>
#include "d3d9.h"
#include <ctime>
#include <iostream>

#define D3DHOOK_TEXTURES
#define MAX_MENU_ITEMS 6
#define WALLHACK 0
#define CUSTOM_CROSSHAIR 1
#define NO_RECOIL 2
#define UNLIM_AMMO 3
#define AUTO_FIRE 4
#define HIDE_MENU 5

class Hacks {
public:
    int m_Stride;

    void Hacks::CreateFont(IDirect3DDevice9 *d3dDevice, std::string choiceFont);
    void Hacks::InitializeMenuItems();
    void Hacks::DrawText(LPCSTR TextToDraw, int x, int y, D3DCOLOR Color);
    void Hacks::DrawMenu(IDirect3DDevice9 *d3dDevice);
    void Hacks::DrawFilledRectangle(int x, int y, int w, int h, D3DCOLOR Color, IDirect3DDevice9 *d3dDevice);
    void Hacks::DrawBorderBox(int x, int y, int w, int h, int thickness, D3DCOLOR Color, IDirect3DDevice9 *d3dDevice);
    void Hacks::KeyboardInput();

    LPDIRECT3DTEXTURE9 texRed;
    LPDIRECT3DTEXTURE9 texGreen;
    LPDIRECT3DTEXTURE9 texBlue;
    LPDIRECT3DTEXTURE9 texWhite;

    D3DVIEWPORT9 ViewPort;

    LPD3DXFONT Font;

    struct d3dMenuHack {
        bool on;
        std::string name;
    };

    d3dMenuHack hack[MAX_MENU_ITEMS];
};

The error is ocouring when i am declaring the "void Hacks::"... functions. Any suggestions?

Answer 1

Maybe nikau6's answer is not so clear at first sight because the code seems identical to the one in the OP.

So, the solution is to remove Hacks:: from all your declarations

Answer 2

While building a legacy Direct Show filter in Visual Studio 2019 I had to set Conformance Mode to No. This allows the code to not conform to the standard /permissive-

The above is poor practice as stated by several people. But with legacy code it's often the not appropriate(or possible) to make it follow best practices.
