LVM_GETNEXTITEM message

Searches for a list-view item that has the specified properties and bears the specified relationship to a specified item. You can send this message explicitly or by using the ListView_GetNextItem macro.

Parameters

wParam

Index of the item to begin the search with, or -1 to find the first item that matches the specified flags. The specified item itself is excluded from the search.

lParam

Specifies the relationship to the item specified in wParam. This can be one or a combination of the following values:

Value	Meaning
Searches by index.
LVNI_ALL	Searches for a subsequent item by index, the default value.
LVNI_PREVIOUS	Windows Vista and later: Searches for an item that is ordered before the item specified in wParam. The LVNI_PREVIOUS flag is not directional (LVNI_ABOVE will find the item positioned above, while LVNI_PREVIOUS will find the item ordered before.) The LVNI_PREVIOUS flag basically reverses the logic of the search performed by the LVM_GETNEXTITEM or LVM_GETNEXTITEMINDEX messages.
Searches by physical relationship to the index of the item where the search is to begin.
LVNI_ABOVE	Searches for an item that is above the specified item.
LVNI_BELOW	Searches for an item that is below the specified item.
LVNI_TOLEFT	Searches for an item to the left of the specified item.
LVNI_TORIGHT	Searches for an item to the right of the specified item.
LVNI_DIRECTIONMASK	Windows Vista and later: A directional flag mask with value as follows: LVNI_ABOVE | LVNI_BELOW | LVNI_TOLEFT | LVNI_TORIGHT.
The state of the item to find can be specified with one or a combination of the following values:
LVNI_CUT	The item has the LVIS_CUT state flag set.
LVNI_DROPHILITED	The item has the LVIS_DROPHILITED state flag set
LVNI_FOCUSED	The item has the LVIS_FOCUSED state flag set.
LVNI_SELECTED	The item has the LVIS_SELECTED state flag set.
LVNI_STATEMASK	Windows Vista and later: A state flag mask with value as follows: LVNI_FOCUSED | LVNI_SELECTED | LVNI_CUT | LVNI_DROPHILITED.
Searches by appearance of items or by group
LVNI_VISIBLEORDER	Windows Vista and later: Search the visible order.
LVNI_VISIBLEONLY	Windows Vista and later: Search the visible items.
LVNI_SAMEGROUPONLY	Windows Vista and later: Search the current group.
If an item does not have all of the specified state flags set, the search continues with the next item.

Return value

Returns the index of the next item if successful, or -1 otherwise.

Remarks

Note that the following flags, for use only with Windows Vista, are mutually exclusive of any other flags in use: LVNI_VISIBLEONLY, LVNI_SAMEGROUPONLY, LVNI_VISIBLEORDER, LVNI_DIRECTIONMASK, and LVNI_STATEMASK.
