代码如下:
#include "stdafx.h"   
#include "windows.h"   
#include "tlhelp32.h"   
void ListProcess()   
{   
        HANDLE handle=CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);   
        PROCESSENTRY32* info=new PROCESSENTRY32;   
        info->dwSize=sizeof(PROCESSENTRY32);   
        int i=0;   
        if(Process32First(handle,info))   
        {   
                if(GetLastError()==ERROR_NO_MORE_FILES )   
                {   
                        printf("没有进程!");   
                }   
                else   
                {   
                        printf("[PID] \t [进程名称] \n");   
                        //printf("%5d \t %s \n",info->th32ProcessID,info->szExeFile);   
                        i++;   
                        while(Process32Next(handle,info)!=FALSE)   
                        {   
                        printf("%5d \t %s \n",info->th32ProcessID,info->szExeFile);   
                        i++;   
                        }   
                }   
        }   
        CloseHandle(handle);   
        delete info;   
}   
   
int main(int argc, char* argv[])   
{   
        ListProcess();   
        return 0;   
}  

在这个程序中stdafx.h不用也罢.

但其他程序用了找不到这个头文件，不用又不行那怎么办？

VC中新建一个MFC工程就有了！
