方法一：

    //Qt开源库， 通过QProcess启动系统命令“tasklist.exe”, 获取正在运行的进程QProcess process;process.start("tasklist.exe");if(process.waitForFinished()){QByteArray result = process.readAll();｝

方法二：

    //如果系统找不到Psapi.h//需要安装microsoft sdk, https://www.microsoft.com/en-us/download/details.aspx?id=8279#include <Psapi.h>unsigned long aProcesses[1024], cbNeeded, cProcesses;//枚举所有进程IDif( !EnumProcesses(aProcesses,sizeof(aProcesses),&cbNeeded) ){qDebug()<<"text01"; //Qt开源库，输出字符串}QStringList lprocess;   //Qt开源库，字符串列表//计算有多少个进程cProcesses = cbNeeded / sizeof(unsigned long);for(unsigned int i = 0; i < cProcesses; i++){if(aProcesses[i] == 0){continue;}//获取已存在的进程对象句柄HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, 0, aProcesses[i]);wchar_t buffer[50];GetModuleBaseName(hProcess, 0, buffer, 50); //获取进程名CloseHandle(hProcess);lprocess << QString::fromWCharArray(buffer); //Qt开源库}qDebug()<<lprocess; //Qt开源库

终止进程：

    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 processNameif(wcsicmp(pe.szExeFile, processName)==0){id = pe.th32ProcessID;break;}}CloseHandle(hSnapshot);//if(id == 0)//  return ;//Kill The ProcessHANDLE hProcess = OpenProcess( PROCESS_ALL_ACCESS, FALSE, id );if (hProcess != NULL){TerminateProcess(hProcess,0);CloseHandle(hProcess);}return 1;}
