Enumerating application's process name only - winapi

Question

How to list process names only? I looked at Enumerating All Modules For a Process. The example code works with process names and modules, but I want only process names.
#include "stdafx.h"
#include <windows.h>
#include <tchar.h>
#include <stdio.h>
#include <psapi.h>
#include <iostream>
using namespace std;
int main()
{
DWORD aProcesses[1024], cbNeeded, cProcesses;
unsigned int i;
HANDLE hProcess;
if (!EnumProcesses(aProcesses, sizeof(aProcesses), &cbNeeded))
{
return 1;
}
cProcesses = cbNeeded / sizeof(DWORD);
for (i = 0; i < cProcesses; i++)
{
DWORD processID = aProcesses[i];
cout << processID << endl;
hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, processID);
}
CloseHandle(hProcess);
return 0;
}

Get the process ids using your code and then use EnumProcessModules in combination with GetModuleBaseName to print the name of all the executables.
#include <windows.h>
#include <stdio.h>
#include <tchar.h>
#include <psapi.h>
void PrintProcessName( DWORD processID )
{
TCHAR szProcessName[MAX_PATH] = TEXT("<unknown>");
// Get a handle to the process.
HANDLE hProcess = OpenProcess( PROCESS_QUERY_INFORMATION |
PROCESS_VM_READ,
FALSE, processID );
// Get the process name.
if (NULL != hProcess )
{
HMODULE hMod;
DWORD cbNeeded;
if ( EnumProcessModules( hProcess, &hMod, sizeof(hMod),
&cbNeeded) )
{
GetModuleBaseName( hProcess, hMod, szProcessName,
sizeof(szProcessName)/sizeof(TCHAR) );
}
}
// Print the process name and identifier.
_tprintf( TEXT("%s\n"), szProcessName );
// Release the handle to the process.
CloseHandle( hProcess );
}
int main( void )
{
// Get the list of process identifiers.
DWORD aProcesses[1024], cbNeeded, cProcesses;
unsigned int i;
if ( !EnumProcesses( aProcesses, sizeof(aProcesses), &cbNeeded ) )
{
return 1;
}
// Calculate how many process identifiers were returned.
cProcesses = cbNeeded / sizeof(DWORD);
// Print the name and process identifier for each process.
for ( i = 0; i < cProcesses; i++ )
{
if( aProcesses[i] != 0 )
{
PrintProcessName( aProcesses[i] );
}
}
return 0;
}
