Question

我正在尝试查找正在运行的进程并从我的应用程序中删除它。以下是我的代码。

bool ProcessKill()
 {
    PROCESSENTRY32 process;
    Logger::getInstance()->test(L" checking the call kill status");
    ZeroMemory(&process, sizeof(process));
    process.dwSize = sizeof(PROCESSENTRY32);

    HANDLE snapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, NULL);
      if( snapshot == INVALID_HANDLE_VALUE )
        {
        Logger::getInstance()->test( TEXT(" CreateToolhelp32Snapshot (of processes)") );
        return( FALSE );
        }
    Logger::getInstance()->test(L" checking the call kill status 2222");
    if (Process32First(snapshot, & process) != FALSE)
        {
            Logger::getInstance()->test(L"checking the kill status");
                while(Process32Next(snapshot, &process) == TRUE)
                    { Logger::getInstance()->test(L"1111");
                        if (wcsicmp(process.szExeFile, L"kill.exe") == 0)
                            {  
                                Logger::getInstance()->test(L"found kill running");
                                HANDLE hProcess_Name = OpenProcess(PROCESS_ALL_ACCESS, FALSE, process.th32ProcessID);
                                DWORD dwRet = ::WaitForSingleObject(hProcess_Name, 5000);
                                if (dwRet == WAIT_OBJECT_0)
                                dwRet = ERROR_SUCCESS;
                                //Logger::getInstance()->test(L"kill is running");
                                else
                                    {
                                        ::TerminateProcess(hProcess_Name, 1);
                                        ::CloseHandle(hProcess_Name);
                                        Logger::getInstance()->test(L"kill is terminated");
                                        CloseHandle(snapshot);
                                        return 1;

                                    }

                            }
                    }
    }
    else
    {
        Logger::getInstance()->test(L" Process32First the call kill status 333");
    }
    CloseHandle(snapshot);
    return 0;
}

我观察到Process32First失败了它返回false。任何人都可以让我知道失败背后的原因以及如何解决这个问题。任何解决方法。

在if (Process32First(snapshot, & process) != FALSE)之前添加波纹管语句：

pe32.dwSize = sizeof(PROCESSENTRY32W);

如MSDN中所述：

tagPROCESSENTRY32结构：

typedef struct tagPROCESSENTRY32 {
  DWORD     dwSize;
  DWORD     cntUsage;
  DWORD     th32ProcessID;
  ULONG_PTR th32DefaultHeapID;
  DWORD     th32ModuleID;
  DWORD     cntThreads;
  DWORD     th32ParentProcessID;
  LONG      pcPriClassBase;
  DWORD     dwFlags;
  CHAR      szExeFile[MAX_PATH];
} PROCESSENTRY32;

dwSize

在调用Process32First函数之前，将此成员设置为sizeof(PROCESSENTRY32)。如果不初始化dwSize，则Process32First失败。

即使进程正在运行，Process32First也不会返回TRUE
