MFC之IP控件(IP地址与CString的互相转化)

1.获得IP地址：

CIPAddressCtrl * pIP = (CIPAddressCtrl*)GetDlgItem(IDC_IPADDRESS1);
BYTE nf1, nf2, nf3, nf4;
pIP->GetAddress(nf1, nf2, nf3, nf4);
CString str;
str.Format(_T("%d.%d.%d.%d"), nf1, nf2, nf3, nf4);//这里的nf得到的值是IP值了
MessageBox(str);

2.设置IP地址

CIPAddressCtrl * pIP = (CIPAddressCtrl*)GetDlgItem(IDC_IPADDRESS1);
BYTE nf1 = 123, nf2 = 12, nf3 = 13, nf4 = 15;
pIP->SetAddress(nf1, nf2, nf3, nf4);
