Kann man über die Nachricht NM_CLICK an weitere Infos kommen außer an diese in NMHDR, z.B. an die NMMOUSE Struktur? Was kann man mit pResult anfangen außer auf 0 setzen?

NMCLICK *pnmClick = (NMCLICK*)pNMHDR;
Aber Du kommst auch per GetMessagePos an die Cursor Position der Maus ran.

Ergibt 0 und 1031 egal, wohin in IDC_LIST1 geklickt wird. Warum?
...->dwHitInfo funktioniert z.B.

Das ist die Variante mit

::GetCursorPos(...)

Hier allerdings nicht auf das Listenelement, sondern auf den Dialog bezogen,
