Remarks
The callback mask of a list-view control is a set of bit flags that specify the item states for which the application, rather than the control, stores the current data. The callback mask applies to all of the control's items, unlike the callback item designation, which applies to a specific item. The callback mask is zero by default, meaning that the list-view control stores all item state information. After creating a list-view control and initializing its items, you can use the ListView_SetCallbackMask macro or LVM_SETCALLBACKMASK message to change the callback mask. To get the current callback mask, send the LVM_GETCALLBACKMASK message.
For more information about overlay images, state images, and list-view callbacks, see User Interface Services.
