How to use LVM_GETITEM (iSubItem?)

Question

I'm trying to use LVM_GETITEM to get info about an item in a ListView. The message needs 2 parameters to work: iItem and iSubItem among other things. It seems clear that iItem is the index of the desired item in the ListView, but I am unclear what to use for iSubItem .

I've been using 0 and it seems to work just fine for me. Still, I'm curious, what is iSubItem and what is it used for? The documentation is not very enlightening.

Answer 1

iSubItem refers to columns when the listview is in "details" mode ( LVS_REPORT ). The first (primary) column is subitem 0, the second is 1 and so on.
