QT 周期性的杀死一个进程（软件），一分钟后自动退出

article 2024/10/31 21:38:57

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_OBJECT

public:
    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;
}
