EnumProcesses（aProcesses，sizeof（aProcesss），&cbNeeded）｛return1；｝cProcesses=cbNeed/sizeof（DWORD）；对于（i=0；i˂cProcesses；i++）｛if（aProcesses[i]！=0）｛DWORDpid=aProcesses[i]；TCHARszProcessName[MAX_PATH]=TEXT（“？？？”=hProcess）｛HMODULEhMod；DWORDcbNeeded；if（EnumProcessModules（hProcess，&hMod，sizeof（hMod），&cbNeeded））｛GetModuleBaseName（hProcess、hMod、szProcessName、sizeof（szProcessName）/sizeof（TCHAR））；｝printf（“PID:%X%ls”，PID，szProcessName）；CloseHandle（hProcess）；｝｝return0；｝
使用 CreateToolhelp32Snapshot
#include <iostream>
#include <Windows.h>
#include <TlHelp32.h>
#include <Psapi.h>
int main() {
HANDLE hSnap = CreateToolhelp32Snapshot(PROCESS_ALL_ACCESS, 0);
if (hSnap != INVALID_HANDLE_VALUE)
{
PROCESSENTRY32 pe;
pe.dwSize = sizeof(pe);
if (Process32First(hSnap, &pe))
{
do {
printf("PID: %X %ls
", pe.th32ProcessID, pe.szExeFile);
} while (Process32Next(hSnap, &pe));
}
}
CloseHandle(hSnap);
return 0;
}
使用 EnumProcesses
#include <iostream>
#include <Windows.h>
#include <TlHelp32.h>
#include <Psapi.h>
int main() {
DWORD aProcesses[1024], cbNeeded, cProcesses;
size_t i;
if (!EnumProcesses(aProcesses, sizeof(aProcesses), &cbNeeded))
{
return 1;
}
cProcesses = cbNeeded / sizeof(DWORD);
for (i = 0; i < cProcesses; i++)
{
if (aProcesses[i] != 0)
{
DWORD pid = aProcesses[i];
TCHAR szProcessName[MAX_PATH] = TEXT("???");
HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, pid);
if (NULL != hProcess)
{
HMODULE hMod;
DWORD cbNeeded;
if (EnumProcessModules(hProcess, &hMod, sizeof(hMod), &cbNeeded))
{
GetModuleBaseName(hProcess, hMod, szProcessName, sizeof(szProcessName) / sizeof(TCHAR));
}
}
printf("PID: %X %ls
", pid, szProcessName);
CloseHandle(hProcess);
}
}
return 0;
}
