Maps the ID of an item to an index.
The unique ID of an item.
Must be zero.
Returns the most current index.
List-view controls internally track items by index. This can present problems because indexes can change during the control's lifetime.
The list-view control can tag an item with an ID when the item is created. You can use this ID to guarantee uniqueness during the lifetime of the list-view control.
If you need the index of an item after an ID is created you can call LVM_MAPIDTOINDEX with the unique ID and it returns the most current index.
LVM_MAPIDTOINDEX is not supported under the LVS_OWNERDATA style.
In a multithreaded environment, the index is only guaranteed on the thread that hosts the list-view control, not on background threads.
To use this message, you must provide a manifest specifying Comclt32.dll version 6.0. For more information on manifests, see Enabling Visual Styles.
