Anhand eines Hostnamens die IP herauskriegen ...?

[Phill]

Hi,

ist es möglich anhand eines Hostnamens die IP herauszukriegen ?

thx, Phill

[Cplusplus]

Diese Funktion ist so gemacht, dass man ihr als Parameter IP oder Hostname übergeben kann. Sie leifert die IP-Addresse.

CString GetIPbyHost(CString host)
{
	in_addr iaDest;
	iaDest.s_addr = inet_addr(host);
	LPHOSTENT pHost;
	if(iaDest.s_addr == INADDR_NONE)
	{
		pHost = gethostbyname(host);
		if(pHost!=NULL)
		{
			CString ip;
			IN_ADDR in;
			in.S_un.S_addr=*((u_long *)pHost->h_addr_list[0]);
			ip.Format("%s",inet_ntoa(in));
			return ip;
		}
	}
	else
	{
		pHost = gethostbyaddr((const char*)&iaDest, sizeof(struct in_addr), AF_INET);
		if(pHost!=NULL)
		{
			CString ip;
			IN_ADDR in;
			in.S_un.S_addr=*((u_long *)pHost->h_addr_list[0]);
			ip.Format("%s",inet_ntoa(in));
			return ip;
		}
	}
	return "";
}

Bevor du aber diese Funktion aufrufst, muss du dies ausführen:

WSADATA wsaData;
WSAStartup(MAKEWORD(1,1),&wsaData);

Hmm,kannst du mir verraten warum so viele Fehler entstehen obwohl ich die wininet, die winsock2 und die Ws2_32.lib inkludiert habe...?

thx, Phill

[kleine bitte]

bitte nichts vor stdafx.h includen

[Phill]

Wenn ich es so schreibe

#include "stdafx.h"
