c# - Combine List and ObservableCollection -

i have wpf application contains datagrid bound list. list implements inotifypropertychanged interface. can see when property has changed. when new item added or deleted there no event tell me has happened. after reading have seen observablecollection can tell me when item has been added or deleted via collectionchanged event. observablecollection has few short comings list overcomes. so question if it's possible combine list & observablecollection have functionality of both? possible have list inherit from? if there methods need overwritten? the simple answer question 'yes, work'. the observablecollection<t> class extends collection<t> class, implements ilist<t> , icollection<t> , ienumerable<t> , ilist , icollection , ienumerable interfaces - same list<t> class. however, observablecollection<t> class implements inotifycollectionchanged , inotifypropertychanged interfaces, these main difference between

mtu - TCP file Transfer window size -

i'm trying reverse engineer application, , need understanding how tcp window size works. mtu 1460 application transfers file using tcp point b. know following: the file split segments of size 8k each segment compressed then each segment sent point b on tcp. these segment text file can of size 148 bytes, , pdf 6000 bytes. for text file, supposed see segments of 148 attached 1 form 1 large tcp stream? , split according window size? any appreciated. the receiver application should see data in teh same way, sender application sent it. tcp uses byte-streaming , collects bytes in in-order manner , delivers application. mtu largely internal semantics tcp , not take application-layer packet boundaries. if tcp has enough data send in send buffer (each tcp socket has own send buffer, btw), package next segment worth mtu size , sends it; more precise, deducts tcp , ip header mtu size.
