I was just wondering if anyone knows how to convert a IP to UINT when the IP is in a SOCKADDR_IN struct? I tried

  
memcpy(&adrIP->sin_addr, &dwTempIP, 4);
  

But it corrupts the IP.. Any ideas?

I think that IP addresses in the SOCKADDR_IN struct are stored in little endian, which basically means that the ip is stored backwards in memory...

maybe...

Like this:

  unsigned int ip = ntohl( addr.sin_addr.S_addr );  

codeka.com - Just click it.

Or if you dont want to call a function which can be replaced with one line of code then its :
(Note code is in Delphi but easy to convert )

  result := IntToStr(Ord(pRemoteAddress.sin_addr.S_un_b.s_b1)) + '.' + IntToStr(Ord(pRemoteAddress.sin_addr.S_un_b.s_b2))+ '.' + IntToStr(Ord(pRemoteAddress.sin_addr.S_un_b.s_b3))+ '.' + IntToStr(Ord(pRemoteAddress.sin_addr.S_un_b.s_b4));   

note : Ord just casts a Char as an Int
