compiler error error C2228: left of '.AddTail' must have class/struct/union type

I use CList to store my define node but the compiler show this error C2228: left of '.AddTail' must have class/struct/union type message I don;t know what wrong with this error message. my code is as follow

TCHAR title[MAX_LEN];
 TCHAR titlestring[MAX_LEN];
 process_node node1;
 if (IsWindowVisible(hWnd))
 {
  int n=GetWindowText(hWnd, title, MAX_LEN-1);
  if(n>0)
  {
   _tcsncpy_s(titlestring,_countof(titlestring),(LPCTSTR)lparam,_TRUNCATE);
   _tprintf(_T("title=%s\n"),title);
  }
  if(_tcsstr(title,titlestring)!=NULL)
  {
   DWORD id=0;
   TCHAR name[MAX_LEN];
   if(hWnd)
   {
    GetWindowThreadProcessId(hWnd,&id);
    GetProcessName(id,name);
    node1.ProcessID=id;
    node1.ProcessName=name;
    Pr开发者_开发技巧ocessList.AddTail(node1);
    AfxMessageBox(_T("find"));
    _tprintf(_T("title=%s,id=%ld,name=%s\n"), title,id,name);
    return TRUE;//找完還要繼續找下一個因為有可能不只一個
   }
  }
 }
 return TRUE;

ProcessList just not declared. If it does declared somethere else you should add #include to you stdafx file.

You have this line of code:

  ProcessList.AddTail(node1);

My guess is you need something like this line of code:

  ProcessList myProcessList;

  myProcessList.AddTail(node1);
