怎样获得“ip地址控件”的值？

Question

请问使用什么函数可以获得“ip地址控件”的值，并转换成字符串形式。

Answer 1

建立DDX/DDV，和一个CString的值相关联就行了

Answer 2

int GetAddress( BYTE& nField0, BYTE& nField1, BYTE& nField2, BYTE& nField3 );int GetAddress( DWORD& dwAddress );Return ValueThe number of non-blank fields in the IP Address Control.ParametersnField0A reference to the field 0 value from a packed IP address. nField1A reference to the field 1 value from a packed IP address.nField2A reference to the field 2 value from a packed IP address.nField3A reference to the field 3 value from a packed IP address.dwAddressA reference to the address of a DWORD value that receives the IP address. See Res for a table that shows how dwAddress is filled.ResThis member function implements the behavior of the Win32 messageIPM_GETADDRESS, as described in the Platform SDK.In the first prototype above, the numbers in fields 0 through 3 of the control, read left to right respectively, populate the four parameters. In the second prototype above, dwAddress is populated as follows.Field Bits containing the field value 
0 24 through 31 
1 16 through 23

Answer 4

“ip地址控件”的值 是long型，使用HighWord,LowWord,HightByte,LowByte即可，具体查msdn

Answer 5

如下，m_Ip为关联的CIPAddressCtrl控件类型。
BYTE nArrIP[4];
m_Ip.GetAddress(nArrIP[0],nArrIP[1],nArrIP[2],nArrIP[3]);
CString str;
str.Format("%d.%d.%d.%d",nArrIP[0],nArrIP[1],nArrIP[2],nArrIP[3]);
