windows 8 - Tile notification doesn't work if image doesn't exist at specified uri -

-

at server side send tile notifications via uri:

<?xml version='1.0' encoding='utf-8'?> <tile>     <visual lang=""en-us"">         <binding template=""tilewidesmallimageandtext02"">             <image id=""1"" src=""{0}""/>             <text id=""1"">{1}</text>             <text id=""2"">{2}</text>         </binding>     </visual> </tile>

{0} uri image e.g. ms-appdata:///local/folder/{id}.jpg problem server doesn't know if specific image exists or not , in case if not - tile notification won't work (tile won't updated) there solutions e.g. specify default image or default binding (without image).

a tile notification shown if of image resources referenced present , valid. fallback different image not possible. isn't possible have tile notification shown if server referencing local images may or may not present on client.

there 2 possible alternatives may of use in situation:

  1. host images on server, available clients.

  2. omit image nodes in xml template may or may not present on clients. of nodes in xml template can removed. taking tile notification xml example, tile notification shown if image node removed:

    <?xml version='1.0' encoding='utf-8'?> <tile>     <visual lang="en-us">         <binding template="tilewidesmallimageandtext02">             <text id="1">first text</text>             <text id="2">second text</text>         </binding>     </visual> </tile>

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.
