请问各位高手,使用Netbios来获取无线网卡Mac地址时,获取失败,跟踪发觉以下红色值为5'|',而正常应该是0,到底为什么呢?万分感谢阿!!

以下是源码:

主要函数1:

void CBasicDlg::OnBnClickedMac()
{
 // TODO: 在此添加控件通知处理程序代码
 LPCTSTR kb;
 NCB ncb;
 CGetNetInfo getnetinfo;
 UCHAR uRetCode;
 LANA_ENUM lana_enum;
 memset(&ncb,0,sizeof(ncb));
 ncb.ncb_command = NCBENUM;
 ncb.ncb_buffer = (unsigned char*)&lana_enum;
 ncb.ncb_length = sizeof(lana_enum);
 uRetCode = Netbios(&ncb);
 
 ASTAT adapter;

 if(uRetCode == 0)
 {
  for(int i = 0;i<lana_enum.length;i++)
  {
      kb = getnetinfo.GetMacAddress(lana_enum.lana[i],adapter);
  }
 }
 GetDlgItem(IDC_EDIT_MAC)->SetWindowText(kb);
}

主要函数2:

LPCTSTR CGetNetInfo::GetMacAddress(int lana_num,ASTAT &adapter)
{
 NCB ncb;
 UCHAR uRetCode;
 memset(&ncb,0,sizeof(ncb));
 ncb.ncb_command = NCBRESET;
 ncb.ncb_lana_num = lana_num;
 uRetCode = Netbios( &ncb );

 memset(&ncb,0,sizeof(ncb));
 ncb.ncb_command = NCBASTAT;
 ncb.ncb_lana_num = lana_num;
 ncb.ncb_buffer = (unsigned char*)&adapter;
 ncb.ncb_length = sizeof(adapter);
 uRetCode = Netbios( &ncb );

 if(uRetCode == 0)
 {
  m_MacAddr[lana_num].b1 = adapter.adapt.adapter_address[0];
  m_MacAddr[lana_num].b2 = adapter.adapt.adapter_address[1];
  m_MacAddr[lana_num].b3 = adapter.adapt.adapter_address[2];
  m_MacAddr[lana_num].b4 = adapter.adapt.adapter_address[3];
  m_MacAddr[lana_num].b5 = adapter.adapt.adapter_address[4];
  m_MacAddr[lana_num].b6 = adapter.adapt.adapter_address[5];
 }
 CString strMac;
 strMac.Format(m_MacAddr[lana_num].b1, m_MacAddr[lana_num].b2, m_MacAddr[lana_num].b3, m_MacAddr[lana_num].b4, m_MacAddr[lana_num].b5, m_MacAddr[lana_num].b6);
 LPCTSTR kb = (LPCTSTR)strMac;
 return kb;
}

一直都没问题,就是到了红色部分该值为5'|',而不是0,到底为什么呢?谢谢!
