與DLL掛鈎的游戲掛鈎

Question

我的DLL

#include <windows.h>
#include <vector>
#include "Funkcje.h"

WNDPROC originalProc;
LRESULT CALLBACK myHookProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam);

BOOL WINAPI DllMain(
    HINSTANCE hinstDLL,
    DWORD fdwreason,
    LPVOID lpReversed)
{
    switch (fdwreason)
    {
    case DLL_PROCESS_ATTACH:
        WNDPROC originalProc = SetWindowLongPtr(getToplevelWindows()[1], GWLP_WNDPROC, (LONG_PTR)myHookProc);
        break;
    }

    return TRUE;
}

LRESULT CALLBACK myHookProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
    LRESULT originalResult = originalProc(hWnd, uMsg, wParam, lParam); // call original first
    if (uMsg == WM_PAINT)
    {
        PAINTSTRUCT ps;
        HDC hdc = GetDC(hWnd);
        TextOut(hdc, 150, 150, L"TEST", 4);
        ReleaseDC(hWnd, hdc);
    }
    return originalResult;
}

我遇到了（LONG_PTR）myHookProc問題。我的編譯器說錯誤C2440：“正在初始化”：無法從“ LONG”轉換為“ WNDPROC”，我不知道我現在能做什么。 沒有（LONG_PTR），我的編譯器會說他不能從'LRESULT'轉換為'LONG'

將簽名更改為：

LRESULT APIENTRY myHookProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)

並致電：

WNDPROC originalProc = (WNDPROC)SetWindowLongPtr(getToplevelWindows()[1], GWLP_WNDPROC, (LONG_PTR)myHookProc);
