Thanks for your reply!
I did it with NotesDocumentCollection like you said, but it got a bad performance, it need to re-search when you click button to "page turn" for every time.
Due to my system design, i can not use way "start and count parameters", so i think that must be put data in somewhere convient to R/W actions.
