代码中用到Qt库的地方， 不使用Qt库的可以替换为自己相应的函数
方法一：
1 //Qt开源库， 通过QProcess启动系统命令“tasklist.exe”, 获取正在运行的进程
2 QProcess process; 3 process.start("tasklist.exe"); 4 if(process.waitForFinished()) 5 { 6 QByteArray result = process.readAll(); 7 ｝
方法二：
1 //如果系统找不到Psapi.h 2 //需要安装microsoft sdk, https://www.microsoft.com/en-us/download/details.aspx?id=8279
3 #include <Psapi.h>
4
5 unsigned long aProcesses[1024], cbNeeded, cProcesses; 6 //枚举所有进程ID
7 if( !EnumProcesses(aProcesses,sizeof(aProcesses),&cbNeeded) ) 8 { 9 qDebug()<<"text01"; //Qt开源库，输出字符串
10 } 11 QStringList lprocess; //Qt开源库，字符串列表 12
13 //计算有多少个进程
14 cProcesses = cbNeeded / sizeof(unsigned long); 15
16 for(unsigned int i = 0; i < cProcesses; i++) 17 { 18 if(aProcesses[i] == 0) 19 { 20 continue; 21 } 22 //获取已存在的进程对象句柄
23 HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, 0, aProcesses[i]); 24 wchar_t buffer[50]; 25 GetModuleBaseName(hProcess, 0, buffer, 50); //获取进程名
26 CloseHandle(hProcess); 27 lprocess << QString::fromWCharArray(buffer); //Qt开源库
28 } 29 qDebug()<<lprocess; //Qt开源库
终止进程：
1 int KillProcess(LPCSTR processName) 2 { 3 PROCESSENTRY32 pe; 4 DWORD id=0; 5 HANDLE hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0); 6 pe.dwSize = sizeof(PROCESSENTRY32); 7 if(!Process32First(hSnapshot,&pe)) 8 { 9 return 0; 10 } 11
12 while(1) 13 { 14 pe.dwSize=sizeof(PROCESSENTRY32); 15 if(Process32Next(hSnapshot,&pe)==FALSE) 16 { 17 break; 18 } 19 //find processName
20 if(wcsicmp(pe.szExeFile, processName)==0) 21 { 22 id = pe.th32ProcessID; 23 break; 24 } 25 } 26 CloseHandle(hSnapshot); 27 //if(id == 0) 28 // return ; 29
30 //Kill The Process
31 HANDLE hProcess = OpenProcess( PROCESS_ALL_ACCESS, FALSE, id ); 32 if (hProcess != NULL) 33 { 34 TerminateProcess(hProcess,0); 35 CloseHandle(hProcess); 36 } 37 return 1; 38 }
