könnte man über ein Excel-Makro (Excel 2000) die IP-Adresse des Rechners
auslesen, evtl.über eine (mehrere) API-Funktion(en) ?

Hallo Udo
Schau dir mal das Posting von James Brown, gepostet in
microsoft.public.vb.winapi
am 6.10.99 unter Subject: Re: Get the computer's ip-adress
Message-ID: <37FAD394...@Brownfamily.com>
an.
Das ist genau das, was du suchst.
Hab's gerade mal unter Excel angetestet. Klappt!
MfG
Michael

Übrigens hab ich seit kurzem das API-Buch v.Dan Appleman, wie Du schon angedeutet hattest, 'try and
error' ist es bei mir zur Zeit noch :).

Michael, Frank,
die Funktion ist wirklich sehr interessant. Danke für diesen Beitrag!
Als Hinweis für Anwender: In den obigen Zeilen sind IP und Hostname
vertauscht, MsgBox muss heändert werden.
