multithreading - C#, Thread, Memory -

today know how save image stream (really in memory it's possible don't use appropriate term) , read thread. to think proceed these steps : - in first thread : 1 - create image object (system.drawing) file 2 - create thumbnail 3 - save thumbnail stream (system.io) 4 - send stream object second thread. b - in second thread : 1 - receive stream first thread 2 - create bitmapimage object stream 3 - displaying on ui. (wpf) thks. i've retrieve part of code show did : in thread check images in folders : public void createimgobj(object sender) { try { filestream fs = file.open((string)sender, filemode.open); bitmap dimg = new bitmap(fs); memorystream ms = new memorystream(); dimg.save(ms, system.drawing.imaging.imageformat.jpeg); bitmapimage bi_img = new bitmapimage(); bi_img.begininit(); bi_img.streamsource = new memorystream(ms.toarray()); bi_img.endinit(); ...

c++ - "typename qualified-id" referring to a type in a non-type parameter-declaration -

14.1 [temp.param], paragraph 2 ... typename followed unqualified-id names template type parameter. typename followed qualified-id denotes type in non-type parameter-declaration ... i'm bit confused meaning of bold text. specifically, typename can occur in 2 different contexts ( type-specifier or template-parameter ), 1 refer to? for former case, considered: struct { struct x { }; int x; }; struct b { struct x { }; }; template<class t> void f(t t) { typename t::x x; // t can or b } however, neither a::x nor b::x non-type parameter-declaration (they member-declaration s). for latter case, i'm not sure why that's necessary. why not directly write down type qualified-id ? parameterization necessary? this about struct s { typedef int x; }; template <typename t, typename t::x> void f() { } int main() { f<s, 1>(); } here, typename t means t named template type parameter, typename t::x type of un...
