ps：toolhelp函数在64位上貌似不行了

参照msdn的例子，用EnumProcesses（）枚举进程并输入进程名和句柄。以下代码在vs2008中测试通过：

#include "stdafx.h"#include <windows.h>#include "psapi.h"#pragma   comment   (lib, "psapi.lib ")  void MyEnumProcess(){// Get the list of process identifiers.DWORD aProcesses[1024], cbNeeded, cProcesses;unsigned int i;if ( !EnumProcesses( aProcesses, sizeof(aProcesses), &cbNeeded ) )       //枚举进程return;cProcesses = cbNeeded / sizeof(DWORD);             //计算进程个数for ( i = 0; i < cProcesses; i++ )if( aProcesses[i] != 0 ){TCHAR szProcessName[MAX_PATH] = TEXT("<unknown>");HANDLE hProcess = OpenProcess( PROCESS_QUERY_INFORMATION |PROCESS_VM_READ,FALSE, aProcesses[i] );     //获得进程句柄if (NULL != hProcess ){HMODULE hMod;DWORD cbNeeded;if ( EnumProcessModules( hProcess, &hMod, sizeof(hMod), &cbNeeded) )        //枚举进程模块信息{GetModuleBaseName( hProcess, hMod, szProcessName, sizeof(szProcessName)/sizeof(TCHAR) );       //取得主模块全名,每个进程第一模块则为进程主模块}}_tprintf( TEXT("%s  (PID: %u)\n"), szProcessName, aProcesses[i] );     //输出进程名及PIDCloseHandle( hProcess );}}void main( ){    MyEnumProcess();system("pause");}
