c++ - Best way to store vector of structures -


i need store sorted bunch of structures. best way in vector? should use pointers or make copy?

struct mystruct {     int i;     string str;     //whatever... };

and then:

vector<mystruct> v;

or

vector<mystruct*> v;

thanks in advance.

storing raw pointers

vector<mystruct*> v;

is bad idea. supposed delete them? safer use smart pointer, e.g. in c++11

vector<std::shared_ptr<mystruct>> v;

or

vector<std::unique_ptr<mystruct>> v;

depending on doing. see here

if have simple value type, easier copy them i.e. suggest

vector<mystruct> v;

otherwise, if want oo polymorphism go pointer base in collection.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
