Maps the unique ID of an item in the current list-view control to an index.

UINT MapIDToIndex(
     UINT id
) const;



[in] id

The unique ID of an item.

The current index for the specified ID.

A list-view control internally tracks 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 and you can use this ID to guarantee uniqueness during the lifetime of the list-view control.

Note that in a multithreaded environment the index is guaranteed only on the thread that hosts the list-view control, not on background threads.

This method sends the LVM_MAPIDTOINDEX message, which is described in the Windows SDK.
