Пасиб щас буду пробовать :)

что то тут не так :(

Pokonkretnee gde che-to ne tak?
P.S.Ya toko vecherom smogu proverit tak shto pogodi;)

Wopros stoit ne sowsem korrektno.
1. U kajdoi mashini est lokalnij adres w setke - 127.0.0.0
2. Dopustim u tebya w kompe eshe setewuha s adresom 192.168.0.1 i ppp soedinenie s IP (twoim) 217.32.14.210. Kakoi iz etih IP togda schitat za tot, kotorij tebe nujen? Obichno proweryaetsya eto tak: otkriwaetsya socketnoe soedinenie s hostom kotorij tebe nujen, naprimer www.yahoo.com i potom i socketa winimaetsya adres lokalnogo interfeisa cherez kotorij proshel konnekt.

так так он может и прокси выдать - нужет тот короче который как сервер работать может(интернет)

S kakih fuev on proxy widast? Ya ne goworiu o HTTP konnekte cherez WININET.DLL. Ya goworiu o soketnom. Na hudoi konec uzai HTTP s web detectom: http://www.glocksoft.net/cgi-bin/jenv.cgi

helldomain
а нельзя поподробней - о том как это сделать?

Ya dumaju mojno. Ya VB ne liubly, objasniu na palcah. W inete walyaetsya kucha samplow, kak uzat socketi iz VB - est wrode i portirowannoe API. Twoya zadacha:
1. Sozdat socket().
2. Zapolnie INADDR.
3. Wizwat connect().
4. Prochitat INADDR_LOCAL.

как я понял на Delphi 6 есть уже встроенная функция для этого - только не совсем понял как ей пользоватся :(

Hmm... Tam est objekt dlya etogo (naskolko ya znaju). Tebe eto na kakom yazike nado? Esli Delphi ili C mogu nakatat.

helldomain
мне либо Delphi или Visual C++........
Надо так ее запускаешь - и чтоб она зразу показывала IP и Имя компьютера в сети..................если не затруднит - то буду очень признателен :)

Imya kompa w seti - eto DNS. Xex. Poprobuem.

Privet. Derji. Ya ispolzowal biblioteki SYNAPSE - lomitsya cherez sockets napryamuju nehotelos.

Пасибо все работает - только еще о Дэльфи..........как сделать так - если у свойства окна убираешь полоску за которую тоскать окно и кнопки все эти стандартные........то как можно написать такой объект чтоб при Dgar - можно было тоскать окно по экрану?

Hmm... Tebe ego taskat nado ili w nego faili wtaskiwat (drag & drop)?

helldomain
WinApi походу будет проще всего!...........ну я хочу оформить - все модно - какое лучшие решение будет???

Malenkaya ikonka wisyaschaya ryadom s chasami i konnektyaschaya servachok, dopustim, raz w 10 minut. Esli na nee mishu nawesti - malenkaya formochka gde-nit w ugolke s twoi IP.

helldomain
ну идея не плохая - а крешение для оформления самой формы?

Neznaju, ya setewik/sistemshik, a ne aplikushnik. Smotret/dumat nado.

helldomain
а какие есть еще решения кроме WINApi??

Ya ne sowsem ponyal wopros. W konechnom itoge wse pod windami swoditsya k winapi.

helldomain
tak skazat' skin kakimi eshe putjami mozhno sdelat' krome WinApi

Skin mojno sdelat chem ugodno. No wse w rezultate uzajut winapi.

helldomain
А чем потом все это скомпилировать?........и где взять такой компилятор?

Chto znachit chem skompilirowat? Wes winapi w delfiyah w WINDOWS.PAS.

helldomain
да не WIn API a ves' project ?

Nawernoe ya ne ponyal wopros. Ti hochesh narisowat krasiwij gui? Nu tak w chem problema? Kontrolow dlya delphi hot odnim mestom jui. A esli ti hochesh chto-to w stile winamp'a s podderjkoi skinow - tak uzai winapi.

Сорри что вмешиваюсь в вашу дискуссию. Но я так и не понял как на Visual
C++ сделать что бы можно было определить мой IP.

Кто знает как быстро узнать IP адресса удалённых машин?
 

Кто знает как быстро узнать IP адресса удалённых машин в локальной сети, а значение потом загнать в переменную String?

Ba, zdrawstwui topik. Gi.

A chto znachit kak uznat? Spisok wseh mashin w podseti? W predelah dostijenija? W zone DNS? W AS? Chto schitat mashinoi - liuboe setewoe ustroistwo, u kotorogo est w nalichii IP adres, ili tolko to, chto predostawlyaet opredelennie setewie servisi?
