Question

如何仅列出进程名称？我看了Enumerating All Modules For a Process。示例代码使用进程名称和模块，但我只想要进程名称。

#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;
}

使用您的代码获取进程ID，然后将EnumProcessModules与GetModuleBaseName结合使用以打印所有可执行文件的名称。

#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;
}

仅枚举应用程序的进程名称
