C# - Download and Saving images to folder -

-

i'm trying show form displays label "updating, window close once update has finished" download few images files. put on form's shown.

private void frmextraupdater_shown(object sender, eventargs e)     {          (int = 1; < 8; i++)         {             string _emoticonurl = string.format("https://dl.dropboxusercontent.com/u/110636189/mapleemoticons/f{0}.bmp", i);              webrequest requestpic = webrequest.create(_emoticonurl);              webresponse responsepic = requestpic.getresponse();              image webimage = image.fromstream(responsepic.getresponsestream()); // error              webimage.save(application.startuppath + @"\images\f" + + ".bmp");         }     }

however.. once form shown, label doesn't show because doesn't load (it insantly downloades images. want show label , start download).

the other problem throws "a generic error occurred in gdi+." on webimgae.save part reason.

why's that?

oh and.. if folder "images" not exist, automatically create it?

thanks!

here jon skeet suggestion:

system.net.webclient webclient = new system.net.webclient(); webclient.downloadfile(string.format("https://dl.dropboxusercontent.com/u/110636189/mapleemoticons/f{0}.bmp", i), application.startuppath + @"\images\f" + + ".bmp");

use background worker update ui components

backgroundworker backtask = new backgroundworker();     public frmextraupdater()     {         backtask.dowork += backtask_dowork;         backtask.runworkercompleted += backtask_runworkercompleted;     }     private void frmextraupdater_shown(object sender, eventargs e)     {         yourlabel.text = "downloading";         backtask.runworkerasync();     }      void backtask_dowork(object sender, doworkeventargs e)     {         (int = 1; < 8; i++)         {             system.net.webclient webclient = new system.net.webclient();             webclient.downloadfile(string.format("https://dl.dropboxusercontent.com/u/110636189/mapleemoticons/f{0}.bmp", i), application.startuppath + @"\images\f" + + ".bmp");             backtask.reportprogress(i * (100 / 8), string.format("https://dl.dropboxusercontent.com/u/110636189/mapleemoticons/f{0}.bmp", i));         }     }      void backtask_progresschanged(object sender, progresschangedeventargs e)     {         yourlabel.text = "downloading" + e.userstate.tostring();     }      void backtask_runworkercompleted(object sender, runworkercompletedeventargs e)     {         this.close();      }

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
