As the subject suggests, I''m trying to figure out the IP of the local machine. I''ve figured out how to get the host name, but I can''t seem to resolve it to an IP without crashing

Any way to get just the IP? Thanks. --------------------

try this:

  #include <iostream>#include <windows.h>using namespace std;#pragma comment(lib,"ws2_32.lib")void main(){   	WSADATA wsData;	::WSAStartup(MAKEWORD(2,2),&wsData);	char name[512];	::gethostname(name,512);	hostent* phost = ::gethostbyname(name);	sockaddr_in addr;	::memset(&addr,0,sizeof(addr));	::memcpy(&(addr.sin_addr.s_addr),phost->h_addr,4);	char* ip = ::inet_ntoa(addr.sin_addr);	cout << name << ", ip: " << ip << endl;	::WSACleanup();}

Thanks for the quick reply. Ok, I tried that and it crashes

It is very similar to the code I myself wrote. Did I mention I''m writing this app for Windows Pocket PC 2000/2002? I''m not sure if that''ll make a difference... any other ideas?
