iphlpapi.lib and ws2_32.lib is broken

[Farabi]

TCP_Info.obj : error LNK2001: unresolved external symbol _GetTcpTable@12
TCP_Info.obj : error LNK2001: unresolved external symbol _inet_ntoa@4

Any update?

I didn't have time to work the code out very well, but I did verify that GetTcpTable and indirectly iphlpapi.lib at least appear to work OK under Windows 2000.

I tested this code on XP and it compiled and ran ok

Michael:
If you tested it on WinXP and it works okay please tell me. I used the newer version from MASM10 and it still not work too.

I found my mistake
it was because I should wrote it like this on RadAsm

include \masm32\include\iphlpapi.inc
includelib \masm32\lib\iphlpapi.lib


I should know it.
