如Administrator, All user, xxx 等

void   CSDMADlg::GetUsersFromSystemToComboBox(CComboBox   *pCBUsername)   
  {   
  LPUSER_INFO_0   pBuf   =   NULL;   
  LPUSER_INFO_0   pTmpBuf;   
  DWORD   dwLevel   =   0;   
  DWORD   dwPrefMaxLen   =   -1;   
  DWORD   dwEntriesRead   =   0;   
  DWORD   dwTotalEntries   =   0;   
  DWORD   dwResumeHandle   =   0;   
  NET_API_STATUS   nStatus;   
  LPTSTR   pszServerName   =   NULL;//(LPTSTR)GetComputername().GetBuffer(MAX_NAME);   
    
  nStatus   =   NetUserEnum((LPCWSTR)pszServerName,   
  dwLevel,   
  FILTER_NORMAL_ACCOUNT,   //   global   users   
  (LPBYTE*)&pBuf,   
  dwPrefMaxLen,   
  &dwEntriesRead,   
  &dwTotalEntries,   
  &dwResumeHandle);   
    
  pCBUsername->Clear();   
    
  if((nStatus   ==   NERR_Success)   ||   (nStatus   ==   ERROR_MORE_DATA))   
  {   
  if((pTmpBuf=pBuf)!=NULL)   
  {   
  for(DWORD   i=0;i<dwEntriesRead;++i)   
  {   
  pCBUsername->AddString(CString(pTmpBuf->usri0_name));   
  pTmpBuf++;   
  }   
  }   
  }   
  else   
  {   
  ::MessageBox(NULL,"A   system   error   has   occurred","ERROR",MB_OK);   
  }   
    
  if(pBuf!=NULL)   
  {   
  NetApiBufferFree(pBuf);   
  pBuf   =   NULL;   
  }   
    
  while   (nStatus   ==   ERROR_MORE_DATA);   
    
  if   (pBuf   !=   NULL)   
  NetApiBufferFree(pBuf);   
  }
