Qt 모든 프로세스 가져오기, 프로세스 종료

Qt 모든 프로세스 가져오기, 프로세스 종료

방법1:

    //Qt   ，   QProcess      “tasklist.exe”,          
    QProcess process;
    process.start("tasklist.exe");
    if(process.waitForFinished())
    {
        QByteArray result = process.readAll();
    ｝

방법2:

    //       Psapi.h
    //    microsoft sdk, https://www.microsoft.com/en-us/download/details.aspx?id=8279
    #include 

    unsigned long aProcesses[1024], cbNeeded, cProcesses;
    //      ID
    if( !EnumProcesses(aProcesses,sizeof(aProcesses),&cbNeeded) )
    {
        qDebug()<<"text01"; //Qt   ，     
    }
    QStringList lprocess;   //Qt   ，     

    //        
    cProcesses = cbNeeded / sizeof(unsigned long);

    for(unsigned int i = 0; i < cProcesses; i++)
    {
        if(aProcesses[i] == 0)
        {
            continue;
        }
        //            
        HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, 0, aProcesses[i]);
        wchar_t buffer[50];
        GetModuleBaseName(hProcess, 0, buffer, 50); //     
        CloseHandle(hProcess);
        lprocess << QString::fromWCharArray(buffer); //Qt   
    }
    qDebug()<//Qt   

프로세스를 종료하려면 다음과 같이 하십시오.

    int KillProcess(LPCSTR processName)
    {
        PROCESSENTRY32 pe;
        DWORD id=0;
        HANDLE hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
        pe.dwSize = sizeof(PROCESSENTRY32);
        if(!Process32First(hSnapshot,&pe))
        {
            return 0;
        }

        while(1)
        {
            pe.dwSize=sizeof(PROCESSENTRY32);
            if(Process32Next(hSnapshot,&pe)==FALSE)
            {
                break;
            }
            //find processName
            if(wcsicmp(pe.szExeFile, processName)==0)
            {
                id = pe.th32ProcessID;
                break;
            }
        }
        CloseHandle(hSnapshot);
        //if(id == 0)
        //  return ;

        //Kill The Process
        HANDLE hProcess = OpenProcess( PROCESS_ALL_ACCESS, FALSE, id );
        if (hProcess != NULL)
        {
            TerminateProcess(hProcess,0);
            CloseHandle(hProcess);
        }
        return 1;
    }
