网上看到的:


int killpro(string a)
{
cout<<a;
PROCESSENTRY32 pe32;
pe32.dwSize =sizeof(pe32);
HANDLE hpro=::CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
if(hpro==INVALID_HANDLE_VALUE)
 {
     cout<<"call function failed\n";
  return 0;
 }
BOOL nowrun=Process32First(hpro,&pe32);
while(nowrun)
 {
    if(pe32.szExeFile ==a)
  {
 DWORD proid=pe32.th32ProcessID;
 HANDLE hprocess=::OpenProcess(PROCESS_ALL_ACCESS,FALSE,proid);
 if(hprocess!=NULL)
   {
  ::TerminateProcess(hprocess,0);
  ::CloseHandle(hprocess);
   }
  }
    nowrun=::Process32Next(hpro,&pe32);
 }
}


字符串A是当前进程的程序名,它的功能是结束程序.
麻烦对各行做个注解吧...........
