c# - DeleteAsync MobileServices Timed out -

-

i have following code.

the c# code on device, windows phone 8: 

imobileservicetable<subscription> subsciptionstable = app.mobileservice.gettable<subscription>(); subscriptionitemserveritem = await subsciptionstable.where(subs => subs.userid == app.userinfromationid && subs.contentid == holdelement.newmessages).tolistasync();//only want items await subsciptionstable.deleteasync(subscriptionitemserveritem[0]);

where send delete request azure mobileservice. here have following script:

    function del(id, user, request) {     var tablea_table = tables.gettable('subscription');      //console.log("about delete subscription:", id);     tablea_table.where({ userid: user.userid, id: id})         .read ({ success: deleteitem });      function deleteitem(results)     {         if(results > 0){             console.log("reached here", id);             request.execute();         }     }     }

i using script verify user allowed delete requesting, i.e. userdeleting has userid matching userid in table.

everything works , reach 

    request.execute();

but hangs , await on phone, times out. , item not deleted on server either.

what should do? , cause error?

solution

i still did not find error in script. tweaking response got, marked answered found solution be:

function del(id, user, request)  {   var table = tables.gettable('subscription');    table.where({ id: id }).read({     success: function (results)      {       if (results.length > 0)        {         //console.log("log existingitem",results[0].userid);         //console.log("log user",user.userid);         if (results[0].userid == user.userid)          {           request.execute();         }          else          {           // console.log("invalid user");           request.respond(statuscodes.bad_request, "invalid user");         }       }        else        {         // console.log("not_found");         request.respond(statuscodes.not_found);       }     }, error: function () {       //console.log("not_found_error");       request.respond(statuscodes.not_found);     }   }); }

try update "delete" function this:

function delete(item, user, request)  {     var table = tables.gettable('subscription');     table.where({ id: item.id }).read({     success: function (results)      {         if (results.length)          {             var existingitem = results[0];             if (existingitem.userid === user.userid)              {                 request.execute();             }              else              {                 request.respond(statuscodes.bad_request, "invalid user");             }         }          else          {             request.respond(statuscodes.not_found);         }     }, error: function () {     request.respond(statuscodes.not_found);     }     }); }

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.
