Description
OnNeedNewCabinet is a TOnNeedNewCabinet property that represents the event handler signaled when a specific file continues in another cabinet file. OnNeedNewCabinet is signaled in the internal callback function for the Setup API when the SPFILENOTIFY_NEEDNEWCABINET notification is sent during iteration over file members in a .CAB file. OnNeedNewCabinet can be used to allow an application to respond to the disk or path changes need to access the new cabinet file prior to continuing the file operation. The file operation can be abandoned by setting the value in the Cont argument to false in the event handler. Cont is a Boolean parameter that indicates if the Setup API can or should continue to extract files from the new cabinet file. The default value for Cont is True, unless a Win32 error occurs in the Setup API or the event handler changes the value to False. Applications must assign a procedure to the event handler to allow responding to the event notification.
