android - Store and Get Application's Shared Preferences In Activities -

-

I want to save MainActivity in the shared preferences And get it from MenuException I tried to do this:

Main Activity : 

  ISharedPreferences _prefs; ISharedPreferencesEditor Editor = _prefs.Edit (); Editor. Patstrings ("user", type); Editor.Apply ();   
  MenuActivity :  
  ISharedPreferences _prefs = Application.Context.GetSharedPreferences ("user", FileCreationMode.Private);   
 I think I'm not caching  main activity  in the  shared preferences  at the application level  < P> Therefore, any ideas on how to store  shared preferences  globally?   
 
 
 OK, this has changed it:  
  ISharedPreferences _prefs = Application.Context.GetSharedPreferences ("User", FileCreationMode.Private);   
 To do this:  
  ISharedPreferences _prefs = PreferenceManager.GetDefaultSharedPreferences (application.Context);

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

C++ Array Type Not Assignable in Copy Constructor -

-
I have a simple class that represents the triangle, which consists of three arrays square triangle {public: double x [3]; Double y [3]; Unsigned four colors [3]; }; I want to create objects in this square on the heap, then pass on those functions which will use the value from the array. Since I am in these items, I need to make a deep copy to make a copy. Triangle (const triangle and obj) {X = new double [3]; Y = new double [3]; Color = new unsigned char [3]; For (int i = 0; i I keep the following error: "Error: array type 'double [3]' is not assignable for each of the three arrays. I am taking the same view as discussion, and I do not know why I am unable to create a new array. The answer is also the same approach. Does anyone have any insights? Looks like I'm really stupid. I'm taking the same approach as discussed in this video. In the video, you can see that he started the array Read on the member-preliminary list and how it is dif...
