LVN_ODCACHEHINT
LVN_ODCACHEHINT pCachehint = (NMLVCACHEHINT *)lParam;Sent by a virtual list view control when the contents of its display area have changed. For example, a list view control sends this notification when the user scrolls the control's display. The LVN_ODCACHEHINT notification message is sent in the form of a WM_NOTIFY message.
- The application receiving this notification must return zero.
- pCachehint
- Address of an NMLVCACHEHINT structure containing information about the range of items to be cached.
Handling this message allows the application to update the item information held in cache so that it is readily available when an LVN_GETDISPINFO notification message is sent.
Note that this message is not always an exact representation of the items that will be requested by LVN_GETDISPINFO. Therefore, if the requested item is not cached while handling LVN_GETDISPINFO, the application must be prepared to supply the requested information from a source outside the cache.
