Wireless DHCP Address

I am developing an app on a Windows Mobile 2003 SE with built in
Wireless B. I need to find a way to get the IP address of the device
on the wireless network programmatically. Any help is much
appreciated.

You want to use the gethostname and gethostbyname functions (I'm assuming
your language/environment is EVC++):

HOSTENT *lpHostEnt;
char szHostName[256];

gethostname(szHostName, sizeof(szHostName));
lpHostEnt = gethostbyname(szHostName);



Your IP addresses are in lpHostEnt->h_addr_list, which is an array of
in_addr structures.

lpHostEnt->h_addr_list[0].S_un.S_un_b.b1 is the first byte of the first
address, lpHostEnt->h_addr_list[0].S_un.S_un_b.b2 is the second byte of the
first address, etc.

Thanks for the info Brian.

I also used VB.NEt to access the IP using the following code.

Dim sHostName As String
Dim i As Integer
sHostName = System.Net.Dns.GetHostName()
Dim ipE As System.Net.IPHostEntry =
System.Net.Dns.GetHostByName(sHostName)
Dim ipA() As System.Net.IPAddress = ipE.AddressList
For i = 0 To ipA.GetUpperBound(0)
lblInfo.Text = "ip (" & i & ") : " & ipA(i).ToString
