简易按键精灵制作
参考链接：https://docs.microsoft.com/zh-cn/windows/win32/api/winuser/nf-winuser-sendinput?redirectedfrom=MSDN、https://www.fluentcpp.com/2018/12/28/timer-cpp/、https://github.com/99x/timercpp
具体实现见代码，同时可以设置定时器进行定时操作按键。
按键代码实现（注意必须通过管理员身份运行生成的可执行文件才有效）：
#include <iostream> #include <Windows.h> #include <tchar.h> #include "timer.h" // The reference between key and code connection can be found below: // https://docs.microsoft.com/en-us/windows/win32/inputdev/virtual-key-codes /***************************************************************/ /* 全局定义 */ /***************************************************************/ constexpr size_t ARRAY_MAX_SIZE = 4; /***************************************************************** 功能描述: 发送按键消息 其他说明: *******************************************************************/ void GenerateKeyMsg(HWND hwnd, DWORD keyVal) { std::cout << "Post message start. -->"; LPARAM lparam = (MapVirtualKey(keyVal, 0) << 16) + 1; PostMessage(hwnd, WM_KEYDOWN, keyVal, lparam); std::this_thread::sleep_for(std::chrono::milliseconds(static_cast<size_t>(50))); PostMessage(hwnd, WM_KEYUP, keyVal, lparam); std::this_thread::sleep_for(std::chrono::milliseconds(static_cast<size_t>(10))); std::cout << " Post message finish." << std::endl; } int main() { std::cout << "Input time interval:" << std::endl; int delay; std::cin >> delay; // 获取MapleStory句柄 auto ms = FindWindow(NULL, _T("MapleStory")); if (ms == NULL) { std::cout << "No game is found." << std::endl; return 0; } // 界面最前显示 if (!SetForegroundWindow(ms)) return 0; Timer timer; timer.setInterval(std::bind(GenerateKeyMsg, ms, 0x43), delay); timer.loop(); return 0; }
定时器实现：
#include <iostream> #include <thread> #include <chrono> #include <functional> class Timer { bool clear = false; public: void setTimeout(std::function<void(void)> func, float delay); void setInterval(std::function<void(void)> func, float delay); void stop(); void loop(); }; void Timer::setTimeout(std::function<void(void)> func, float delay) { this->clear = false; std::thread t([=]() { if (this->clear) return; std::this_thread::sleep_for(std::chrono::milliseconds(static_cast<size_t>(delay * 1000))); if (this->clear) return; func(); }); t.detach(); } void Timer::setInterval(std::function<void(void)> func, float delay) { this->clear = false; std::thread t([=]() { while (true) { if (this->clear) return; std::this_thread::sleep_for(std::chrono::milliseconds(static_cast<size_t>(delay * 1000))); if (this->clear) return; func(); } }); t.detach(); } void Timer::stop() { this->clear = true; } void Timer::loop() { while (!this->clear) { } }
完善后包含有按键处理的代码，可以使用notepad测试
