listview - Ignore item in FileList Delphi -

-

i'm making simple file manager, using delphi. use listview show folders , files , use filelist(it's not visible) files , folders names directory.

the problem want not include [.] element (it's symbol of current dir, don't know why delphi's filelist shows it) in listview. but, when try ignore it(here's code)

procedure tfolderframe.showfiles; var   i: integer;   size: int64;   filename, extension: string; begin   edt1.text := currentfullpath;   lvlistview.clear;   fllstfiles.directory := currentfullpath;    := 0 fllstfiles.items.count-1 begin     filename := fllstfiles.items.strings[i];    extension := uppercase(extractfileext(filename));     size := dsifilesize(filename);     delete(extension, 1, 1);      if (filename <> '[.]') begin //error apperas @ line!        if (not(isdirectory(filename))) begin         lvlistview.items.add.caption := filename;         lvlistview.items[i].subitems.add(inttostr(size));         lvlistview.items[i].subitems.add(extension);         lvlistview.items[i].imageindex := getitemimage(filename, extension);       end       else begin         delete(filename, 1, 1);         delete(filename, length(filename), 1);         lvlistview.items.add.caption := filename;         lvlistview.items[i].imageindex := getitemimage(filename, extension);       end;     end;   end; end;

an error appers

access violation @ address 004634df in module file_manager.exe. read of adress 00000010

what i've done wrong?

you're not adding item in each iteration in loop. when skip [.], should av lvlistview.items[i] in next iteration, because index of item added i-1. resolve, keep reference item add , work on it.

var   ..   item: tlistitem; begin   ..         item := lvlistview.items.add;         item.caption := filename;         item.subitems.add(inttostr(size));         item.subitems.add(extention);         item.imageindex := getitemimage(filename, extention);       ..

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.
