Question

怎样根据进程名得到其 ID（我想得到Explorer.exe的ID）

Answer 1

列举当前所有进程，找到进程名符合你要求的进程idvoid CEnumProcessView::GetNTPsInfo()
{
ENUMPROCESSES EnumProcesses;
ENUMPROCESSMODULES EnumProcessModules;
GETMODULEFILENAME GetModuleFileName;
GETPROCESSMEMORYINFO GetProcessMemoryInfo;
PROCESS_MEMORY_COUNTERS  MemoryInfo;
FILETIME flKernelTime;
FILETIME flUserTime;
FILETIME flCreateTime;
FILETIME flExitTime;
FILETIME flTotalTime;
SYSTEMTIME stSystemTime;
DWORD dwProcID[1024];
DWORD dwProcNum;
HMODULE ModuleID[1024];
DWORD dwModuleNum;
char cFileName[MAX_PATH];
DWORD i = 0;
HANDLE hProcess; hPsapi = LoadLibrary("psapi.dll");
if(hPsapi == NULL)
{
MessageBox("Load psapi.dll error");
return;
} EnumProcesses = (ENUMPROCESSES)GetProcAddress((HINSTANCE)hPsapi, "EnumProcesses");
EnumProcessModules = (ENUMPROCESSMODULES)GetProcAddress((HINSTANCE)hPsapi, "EnumProcessModules");
GetModuleFileName = (GETMODULEFILENAME)GetProcAddress((HINSTANCE)hPsapi, "GetModuleFileNameExA");
GetProcessMemoryInfo = (GETPROCESSMEMORYINFO)GetProcAddress((HINSTANCE)hPsapi, "GetProcessMemoryInfo");
if(EnumProcesses == NULL || GetProcessMemoryInfo == NULL
|| GetModuleFileName == NULL || GetProcessMemoryInfo == NULL)
{
MessageBox("GetProcAddress() error");
return;
} EnumProcesses(dwProcID, sizeof(dwProcID), &dwProcNum);
dwProcNum = dwProcNum / sizeof(DWORD);
for(i = 0; i < dwProcNum; i++)
{
hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, dwProcID[i]);
DWORD dwRet = GetLastError();
EnumProcessModules(hProcess, ModuleID, sizeof(ModuleID), &dwModuleNum);
dwModuleNum = dwModuleNum / sizeof(HMODULE);
if(GetModuleFileName(hProcess, ModuleID[0], cFileName, sizeof(cFileName)))
{
GetProcessTimes(hProcess, &flCreateTime, &flExitTime, &flKernelTime, &flUserTime);
// DwordToFileTime((FileTimeToDword(&flKernelTime) - FileTimeToDword(&flCreateTime)) 
// + (FileTimeToDword(&flUserTime) - FileTimeToDword(&flCreateTime)), &flTotalTime);
// FileTimeToSystemTime(&flTotalTime, &stSystemTime);
GetProcessMemoryInfo(hProcess, &MemoryInfo, sizeof(PROCESS_MEMORY_COUNTERS));
strcpy(m_ProcessInfoList[m_ProcessCount].cFileName, cFileName);
m_ProcessInfoList[m_ProcessCount].dwProcessID = dwProcID[i];
m_ProcessInfoList[m_ProcessCount].iMemSize = MemoryInfo.WorkingSetSize / 1024;
m_ProcessCount++;
}

CloseHandle(hProcess);
}
}

Answer 2

void CEnumProcessView::GetWin9xPsInfo()
{
HANDLE hProcess;
PROCESSENTRY32 pePsEntry; pePsEntry.dwSize = sizeof(pePsEntry);

hProcess = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0); if(Process32First(hProcess, &pePsEntry))
{
while(1)
{
if(!Process32Next(hProcess, &pePsEntry))
{
break;
}
strcpy(m_ProcessInfoList[m_ProcessCount].cFileName, pePsEntry.szExeFile);
m_ProcessInfoList[m_ProcessCount].dwProcessID = pePsEntry.th32ProcessID;
m_ProcessInfoList[m_ProcessCount].iMemSize = 0;
m_ProcessCount++;
}
} CloseHandle(hProcess);
}
