将当前运行的进程列举出来(C++　Code):

 

#include<windows.h>
#include<tlhelp32.h>
//#include <iomanip>
#include<iostream>
using namespace std;

int main()

    int count=0;
    PROCESSENTRY32 pe32;
    //使用这个数据之前设置大小
    pe32.dwSize=sizeof(pe32);

    if(hProcessSnap==INVALID_HANDLE_VALUE)
    {
        cout<<"CreateToolhelp32Snapshot调用失败!"<<endl;
        return -1;
    }
    //遍历进程快照，轮流显示每个进程信息
    BOOL bMore=::Process32First(hProcessSnap,&pe32);
    cout<<"进程名称/t/t/t/t/t进程ID号"<<endl;
    while(bMore)
    {
  //stricmp()：比较字符串时忽略大小写；strcmp:比较字符串时，不会忽略大小写
  if(stricmp(pe32.szExeFile, "QQ.exe") == 0) //判断当前进程名是不是QQ.exe
   cout<<"Find the process-QQ.exe, PID="<<pe32.th32ProcessID<<endl;

        //cout<<pe32.szExeFile<<"/t/t/t/t/t"<<pe32.th32ProcessID<<endl;  //输出进程名和进程ID
        count++;
        bMore=::Process32Next(hProcessSnap,&pe32);
    }
    cout<<"当前运行进程总数为:"<<count<<endl;
    ::CloseHandle(hProcessSnap);
    return 0;
