VC++ 将IP字符串转为 DWORD值

CString strIP="192.168.1.184";

DWORD dwAddress= ntohl( inet_addr(strIP));

m_IPAddr.SetAddress(dwAddress);

DWORD dwMainServerIP;
m_MainServerIPCtrl.GetAddress(dwMainServerIP);
strMainServerIP.Format(_T("%d.%d.%d.%d"),
(dwMainServerIP>>24)&0xff,
(dwMainServerIP>>16)&0xff,
(dwMainServerIP>>8)&0xff,
dwMainServerIP&0xff ) ;
