窗口看门狗与独立看门狗的代码

窗口看门狗代码：

#include <Windows.h>

int main()
{
    HWND hwnd = FindWindow(NULL, "Window Title"); // 替换为目标窗口的标题
    if (hwnd == NULL)
    {
        MessageBox(NULL, "Window not found!", "Error", MB_OK);
        return 1;
    }

    DWORD pid;
    GetWindowThreadProcessId(hwnd, &pid);

    HANDLE hProcess = OpenProcess(PROCESS_TERMINATE, FALSE, pid);
    if (hProcess == NULL)
    {
        MessageBox(NULL, "Failed to open process!", "Error", MB_OK);
        return 1;
    }

    while (true)
    {
        if (IsWindowVisible(hwnd))
        {
            Sleep(1000); // 每隔一秒检查一次窗口是否存在
        }
        else
        {
            TerminateProcess(hProcess, 0); // 关闭目标进程
            CloseHandle(hProcess);
            return 0;
        }
    }
}

独立看门狗代码：

#include <Windows.h>

int main()
{
    DWORD pid = GetCurrentProcessId();

    while (true)
    {
        HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION, FALSE, pid);
        if (hProcess == NULL)
        {
            MessageBox(NULL, "Process not found!", "Error", MB_OK);
            return 1;
        }

        DWORD exitCode;
        if (GetExitCodeProcess(hProcess, &exitCode) && exitCode != STILL_ACTIVE)
        {
            // 进程已退出
            CloseHandle(hProcess);
            return 0;
        }

        CloseHandle(hProcess);

        Sleep(1000); // 每隔一秒检查一次进程是否存在
    }
}
