Netværks programmering

Der bruges string, så du skal tilføje:
#include <string>
I toppen.

Der er iøvrigt et simpelt eksempel på at hente en side fra internettet her:

Jeg nu lavet den op i klasser og jeg får nu denne fejl:

Jeg er da kun til besvær

Ej bare glem det, så må jeg vende tilbage til det senere, og så starte med at lave et GUI.

Du skal linke med Ws2_32.lib

Burde VS2005 Pro ikke gøre det selv??

Det ved jeg ikke, men tvivler.
Prøv det...

Kan ikke finde hvor man gør det

Jeg har kun Express udgaven, men mon ikke det er ca. det samme?

Under Project Properties (Alt+F7)
Configuration Properties
Linker
Input
Additional Dependencies
Skriver du: ws2_32.lib

ok det prøver jeg

ok, nu får jeg dette :

Det går da fremad...

Det ser ud til at den tror at du vil lave et windows (/GUI) program og ikke et console program.
Jeg ved ikke hvor du fortæller den at du vil lave et console program.

Prøv at oprette et nyt project, vælg så
Win32 -> Win32 Console Application.

Du kan så copy&paste coden derover (husk også at tilføje ws2_32.lib).

Jeg går ud fra at du har en main i din kode?

VisualC++ er lidt bøvlet.
