Qt实现的根据进程名来结束进程

Posted 2020-08-26 hbcdr

1、头文件及实现部分:

 1 #include <windows.h>
 2 #include <tlhelp32.h>
 3 #include   "psapi.h"
 4 #pragma   comment(lib,"psapi.lib")
 5 
 6 #include <QtCore/QCoreApplication>
 7 #include <QProcess>
 8 
 9 int TerminateProcess(QString ProcessName, QString sPathName = "")
10 {
11     int result = 0;
12     QString processName;
13 
14     //提升进程权限
15     HANDLE hToken;
16     TOKEN_PRIVILEGES tkp;
17     int n = OpenProcessToken(GetCurrentProcess(), TOKEN_ALL_ACCESS, &hToken);
18     LookupPrivilegeValue(NULL, SE_DEBUG_NAME, &tkp.Privileges[0].Luid);
19     tkp.PrivilegeCount = 1;
20     tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
21     n = AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, (PTOKEN_PRIVILEGES)NULL, 0);
22     CloseHandle(hToken);
23 
24     HANDLE hSnapShot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0) ; 
25     PROCESSENTRY32 pInfo; 
26     pInfo.dwSize = sizeof(pInfo);
27     Process32First(hSnapShot, &pInfo);
28     do 
29     {
30         //遍历任务的所有进程
31         processName = (QString::fromUtf16(reinterpret_cast<const unsigned short *>(pInfo.szExeFile)));
32         if (processName == ProcessName) 
33         {
34             //找到该进程 取出pid
35             int nPID = pInfo.th32ProcessID;
36 
37             //已知pid获取路径
38             TCHAR wcPath[MAX_PATH] = {0};
39             HANDLE hProcess = 0;
40             hProcess = OpenProcess(PROCESS_ALL_ACCESS , FALSE, nPID);
41             GetModuleFileNameEx(hProcess, NULL, wcPath, MAX_PATH);
42             CloseHandle(hProcess);
43             QString path = QString::fromUtf16(reinterpret_cast<const ushort *>(wcPath));
44 
45             //如果使用默认参数 直接根据进程名终止进程 否则根据程序路径结束
46             if (sPathName.compare("") == 0 || path == sPathName)
47             {
48                 QString cmd;
49                 cmd = QString("taskkill /F /PID %1 /T").arg(nPID);
50                 QProcess p(0);
51                 p.start(cmd);
52                 p.waitForStarted();
53                 p.waitForFinished();
54                 result ++;
55             }
56         } 
57     } while(Process32Next(hSnapShot, &pInfo)); 
58     CloseHandle(hSnapShot);
59     return result;
60 }

2、使用:

int main(int argc, char *argv[])
{
    //QCoreApplication a(argc, argv);
    TerminateProcess("QQ.exe");
    //return a.exec();
}
