UINT MapIDToIndex(
UINT id
) const;
Parameters
Parameter |
Description |
|---|---|
[in] id |
The unique ID of an item. |
Return Value
The current index for the specified ID.
Remarks
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.
