c# - Using a single control as content of multiple tabs -

-

i have textbox, tabcontrol , simple object called someobject.

i create list<someobject> object , fill dynamic number of someobject.

foreach someobject in list create tabitem give name same value name property in someobject.

here commented code of doing

public partial class mainwindow : window {      list<someobject> list;     textbox textbox = new textbox() { name = "textbox1" };     public mainwindow()     {         initializecomponent();         //create test list of someobject         list = new list<someobject>()         {             new someobject() {name = "italian", description = "italian description"},             new someobject() {name = "german", description = "german description"},             new someobject() {name = "french", description = "french description"}         };          //add tab item each object         foreach(someobject someobj in list)         {             tabcontrol1.items.add(new tabitem { name = someobj.name,header = someobj.name });         }      }      //on selected tabitem changed event set content of tab items null , set content of selected tabitem textbox textbox1     private void tabcontrol1_selectionchanged(object sender, selectionchangedeventargs e)     {          foreach(tabitem tab in (sender tabcontrol).items)         {             tab.content = null;         }         string someobjectnameproperty = ((sender tabcontrol).selecteditem tabitem).name;         textbox.text = list.find(obj => obj.name == someobjectnameproperty).description;         ((sender tabcontrol).selecteditem tabitem).content = textbox;     }      //someobject class     class someobject     {         public string name { get; set; }         public string description { get; set; }     }  }

i did of above because don't want have textbox control inside each tab item, code working there more convienient way achieve same result wpf?

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.
