Delphi typcast tlist items C++ approach -

-

Hello I have a question about some type of casting approach. I am translating some Delphi files into C ++. I have a Delphi declaration of class which is taken from TList and it is a base class for other derivative classes. Type TBaseItem = Class (TObject) Public Process Some Processes; Virtual; abstract; End; Type TBaseClass = Class (TList) Private Function GetItem (Index: Integer): TBaseItem; Process settings (value: TBCITIM; index: integer); Public Property Items [Index: Integer]: Read TBCIT Read Write Guest System Setting; End; Function TBaseClass.GetItem (index: integer): TBCITIM; Start the result: = TBCITAM (inherited goods [index]); End; Process TBaseClass.SetItem (value: TBaseItem; index: integer); Inherited items [index]: = value; End;

These are the two base classes, Tibajitum and TBS classes. So new classes taken from TBIIlitem and TBEidclass have been announced as TchildItim which has been taken from TBsclass. TChildItem is overwriting some method method and what is more important is that TChildtClass is overriding property items in a way that is now returning TParentItem items with TBCIT installation. 

  Type TChildItem = class (TBaseItem) Public Process SomeProcedure; Override; End; Type TChildClass = Class (TBaseClass) Private Function GetItem (Index: Integer): TChildItem; Process SetItem (Value: TChildItem; Index: Integer); Public Property Items [Index: Integer]: TCILEightMaster GetItem Write SetItem; End; TChildClass function .GetItem (index: integer): TChildItem; Start the result: = TBILIT (inherited objects [index]); End; Process TChildClass.SetItem (value: TChildItem; index: integer); Inherited items [index]: = value; End;   
 With this example, I wanted to show how easy the classes and overriding properties can be made. Receiving the right type of item out of the list is done by calling only the parent (asset) property item and by typing the appropriate type of type, it is Delphi Appurch.  
 I wonder how I can translate this part of this code into C ++. Currently I have declared a new base class which has not been obtained from any class and has public preferences in that  
  class TBaseItem {virtual void SomeMethod (); } Class TBaseClass {public: vector & lt; TBaseItem & gt; item; }; Square TChildItem: Public TBaseItem {} Category TChildClass: Public TBaseClass {};   
 and then  
  returns (tciild item) item [idx]   
 Using it means that I Want to use Parent Variables such as vector items and type it in a proper way ... My first impression is that I am going in the wrong direction with that delphi viewpoint.  
 What do you suggest?   
 
 
 Delphi code is outdated and pre-date genetics, Delphi analog to C ++ templates. In the modern Delphi code, those list sections will not exist. Instead of a  TList & lt; TBaseItem & gt;  and  TList & lt; TChildItem & gt; .  
 In the C ++ code you can only type  vector & lt; TBaseItem * & gt;  and  vector & lt; TChildItem * & gt; . There is no point in your C ++ translation to implement  TBaseClass  and  TChildClass .  
 I also correct your vocabulary Delphi properties can not be overridden. New property in  TChildClass  is just a new property.

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

ios - Replace text in UITextView run slowly -

-
I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from. NSString will be used instead of NSMutableString . - (UITableViewCell *) TableView: (UITableView *) Table View CellForOutPath: (NSIndex...
