QT 周期性的杀死一个进程（软件），一分钟后自动退出

1.原因：某软件开机自启动很烦，搞一个程序干掉这个自启动的软件

2.QT代码

• main.cpp

#include "KillXXX.h"
#include <QtWidgets/QApplication>int main(int argc, char *argv[])
{QApplication a(argc, argv);KillXXX k;return a.exec();
}

• KillXXX.h 

#include <QtCore/QObject>class KillXXX : public QObject
{Q_OBJECTpublic:KillXXX(QObject*parent = nullptr);~KillXXX();void KillAppProcess();
private slots:void On_timeout();
private:QTimer* myTimer;int count;
};

• KillXXX.cpp

#include "KillXXX.h"
#include <QTimer>
#include <QProcess>
KillXXX::KillXXX(QObject*parent): QObject(parent)
{count = 0;myTimer = new QTimer(this);connect(myTimer, &QTimer::timeout, this, &KillXXX::On_timeout);myTimer->start(10000);
}KillXXX::~KillXXX()
{
}void KillXXX::KillAppProcess()
{QString processName = "进程名.exe"; // 要关闭的进程名称// 使用taskkill命令关闭进程QString command = "taskkill /F /IM " + processName ;QProcess::startDetached("cmd.exe", QStringList() << "/c" << command);
}void KillXXX::On_timeout()
{if (count >= 6){myTimer->stop();delete myTimer;myTimer = nullptr;this->deleteLater();}KillXXX::KillAppProcess();++count;
}

3.利用windeployqt打包这个.exe文件，加入开机自启动就可以啦
