LVSortProc endp

the error result is gotten for IP address.

[six_L]

does not none encounter the trouble?

[Slugsnack]

can you be a bit more clear as to what your problem actually is ?

[six_L]

the result about ip address is as follwing

100.100.100.1
100.100.100.11
100.100.100.2

You're trying to sort them as strings (alphabetically) when you'd like to sort them as values (numerically.)
So, instead of using a direct strcmp, you can use inet_addr (in winsock) to get the ip-address as a value, then bswap it because it's in network byte-order ('reversed'), and use that as the dword value to compare ip-addresses against each other.

hey,Tedd
Thank you very much.
this is the accurate answer.
