Comments

This message is sent to the ImageList Control's window by itself when an Item is unselected by the user.

You can use this message instead of the L_ILN_ITEMUNSEL command notification when you are sub-classing the ImageList Control.

The lItem member of the LILITEMSEL structure pointed to by lParam will contain the 0-based index of the unselected item.
