  • PHP object help -> unexpected T_OBJECT_OPERATOR

    - by php-b-grader
    Please help me understand: print gettype(new CustomerObject()) prints: "object" (so it is an object) BUT print gettype((new CustomerObject())->get_customer()); prints: unexpected T_OBJECT_OPERATOR If I do it over two lines it works fine $object = new Customer($order->customer_id); print gettype($object); prints: object $customer = $object->get_customer(); print gettype($customer); prints: array It appears that the lines cannot be joined into a single call. Is this correct? and what is the logic behind that?

  • How to group a period of time into yearly periods ? (split timespan into yearly periods)

    - by user315648
    I have a range of two datetimes: DateTime start = new DateTime(2012,4,1); DateTime end = new DateTime(2016,7,1); And I wish to get all periods GROUPED BY YEAR between this period. Meaning the output has to be: 2012-04-01 - 2012-12-31 2013-01-01 - 2013-12-31 2014-01-01 - 2014-12-31 2015-01-01 - 2015-12-31 2016-01-01 - 2016-07-01 Preferably the output would be in IList<Tuple<DateTime,DateTime>> list. How would you do this ? Is there anyway to do this with LINQ somehow ? Oh and daylight saving time is not absolutely critical, but surely a bonus. Thanks!

  • Resource File Links

    - by EzaBlade
    When you create a Silverlight Business Application you get a Silverlight application and a Web application. In the Web/Resources folder of the Silverlight app there are links to the files in the Resources folder of the Web app. These links are exactly like the files they link to in that they are heirarchical with the Resource.Designer.cs file shown as a code-behind file for the Resource.resx file When I try to link to a Resource file in this way I only get the .resx file unless I link to the .Designer.cs file separately. However in this case the Designer.cs file is then shown as a standard code file and not related to the .resx file. Does anyone know how to do this linking correctly?

  • Whats the most useful programming language?

    - by Sebi
    I know this question was here a lot of times and can't be answered at all, but im not looking for a single name, but rather for an advice in my situation. I learned programming with Java and now I'm developing in Java for more or less 5 years (at the university) and I thinks my programming skills their are really ok/average. I have also small experience in C/C++ and C#. Now I have some spare time and I'd like to learn a new language or deepen the knowledge of Java/C/C++. But how to choose the right language to learn? I'd like to learn a language which will be usefull in the future concerning working in a software development business? I know there is no single answer, but I'm sure you could mention some languages that are more usefull than others.

  • C++ shared objets

    - by Klaus
    Hello, I have got four classes A, B, C and D. Class A has a member b of class B. Class B has a member c of class C. A has a member D* dpointer; This hierarchy has to be preserved (in fact this is a GUI with app, window, panel as A, B and C). Now B and C must use a method from *dpointer. Is there something more elegant than giving dpointer as a member of B and C ?

  • Calling a method on an object a bunch of times versus constructing an object a bunch of times

    - by Ami
    I have a List called myData and I want to apply a particular method (someFunction) to every element in the List. Is calling a method through an object's constructor slower than calling the same method many times for one particular object instantiation? In other words, is this: for(int i = 0; i < myData.Count; i++) myClass someObject = new myClass(myData[i]); slower than this: myClass someObject = new myClass(); for(int i = 0; i < myData.Count; i++) someObject.someFunction(myData[i]); ? If so, how much slower?

  • How is a set partitioned into valid and invalid items using LINQ?

    - by Aaron Anodide
    Is there a way to write a single LINQ expression to get the same result of the following code? var validations = new Func<conversion, bool>[] { c => c.affiliate.affiliate_id > 0, c => c.campaign_id > 0 }; var invalidConversions = from c in extractedConversions where validations.Any(valid => !valid(c)) select c; var validConversions = from c in extractedConversions where validations.All(valid => valid(c)) select c;

  • formatting european characters from JSON results

    - by mlecho
    hi, i am building an application that imports JSON results and parses the objects to a table cell. Nothing fancy, but in my results, many of the terms/names are European with characters such as è or ú which come out as \u00E9 or \u00FA. I think these are ASCII ? or unicode? ( i can never keep em staight). Anyway, like all good NSSTring's, i figured there must be a method to fix this, but i am not finding it....any ideas? I am trying to avoid doing something like this: this posting. Thanks all.

  • How to generate JSON object on client side and send it to server?

    - by EugeneS
    I have ExtJS based application. I have compound object on the server side, and have ExtJS window with few tabs for editing different parts of this one object. For example: I Have Compound object "Car" public class Car { public string Name; public string Color; public List Wheels; public List Doors; } And on my ExtJS window i have tabs ("General Info", "Wheels", "Doors") for editing different parts of this object. So what i want: When i want to create a new car i want to generate JSON configuration for my class "Car" like {Name:null; Color:null; Wheels:[]; Doors:[]} then sent it to the client, fill it on the client (without callbacks to server) and after user finishes creating his Car object (he added wheels, doors, set name and color) and press save, I want to sent this filled(generated) JSON object to server and save it to DB. Is it possible? Thanks

  • How to extract List<int> from Dictionary<int, string>?

    - by DaveDev
    I have a method that takes a List<int>, which is a list of IDs. The source of my data is a Dictionary<int, string> where the integers are what I want a list of. Is there a better way to get this than the following code? var list = new List<int>(); foreach (var kvp in myDictionary) { list.Add(pair.Key); } ExecuteMyMethod(list);

  • C++: What is the size of an object of an empty class?

    - by Ashwin
    I was wondering what could be the size of an object of an empty class. It surely could not be 0 bytes since it should be possible to reference and point to it like any other object. But, how big is such an object? I used this small program: #include <iostream> using namespace std; class Empty {}; int main() { Empty e; cerr << sizeof(e) << endl; return 0; } The output I got on both Visual C++ and Cygwin-g++ compilers was 1 byte! This was a little surprising to me since I was expecting it to be of the size of the machine word (32 bits or 4 bytes). Can anyone explain why the size of 1 byte? Why not 4 bytes? Is this dependent on compiler or the machine too? Also, can someone give a more cogent reason for why an empty class object will not be of size 0 bytes?

  • Asp.net static object behaviour

    - by Circadian
    I have the following class as part of an asp.net application. public sealed class SomeClass { private static string appId = Guid.NewGuid().ToString(); public static ReadSomethingFromDb(){} public static WriteSomethingToDb(){} } There are more than one application instances in the same application pool, and they all access the same database. I want the operations performed by the above class to be uniquely tied to the instance that performed it, hence the use of the appId. So adding a record to the database would for example contain a name, address and appId. This has been simplified for discussion purposes. Assuming that I have two instances running at mysite.a and mysite.b the above class would generate two different guids. My problem is that mysite.a sometimes produces more than one guid, which is unexpected. Thank you in advance

  • Flex - Use Variables for Object Attribute Names

    - by Immanuel
    How do you use variables to access Object attributes? Suppose I have an Object declared as follows, var obj:Object = new Object; obj.Name = "MyName"; obj.Age = "10"; How would i do something like this, var fieldName:String = "Name"; var fieldAge:String = "Age"; var Name_Age:String = obj.fieldName + " ," + obj.fieldAge; The code above treats 'fieldName' and 'fieldAge' as attribute name itself. I want to treat the same as a variable, and map the value associated with the variable as the Object attribute name.

  • Add new element in existing object

    - by user3094292
    I am using node.js. I have to add new elements in the object before to send a response to client. user.getMatch(req.user, function(err, match){ for( k=0; k<match.length; k++){ var userId = { id : match[k].match_id }; var user = new User(userId); console.log('k: ' + k); user.getUserInfo(function(err2, info){ console.log('k here: ' + k); if(info){ match[k].foo = info[0].foo; } }); } var response = { data : match }; res.json(response); }); I want to add an element "foo" from user.getUserInfo to the object "match" that was returned by user.getMatch. And then send all the data as response to the client. But it got an error because "k" inside of user.getUserInfo is not equal to the "k" outside. I do not know why the both "k" are not equal. And how will I send a response to the client after performing the loop. Thanks for your help!

  • Can I upload an object in memory to FTP using Python?

    Here's what I'm doing now: mysock = urllib.urlopen('http://localhost/image.jpg') fileToSave = mysock.read() oFile = open(r"C:\image.jpg",'wb') oFile.write(fileToSave) oFile.close f=file('image.jpg','rb') ftp.storbinary('STOR '+os.path.basename('image.jpg'),f) os.remove('image.jpg') Writing files to disk and then imediately deleting them seems like extra work on the system that should be avoided. Can I upload an object in memory to FTP using Python?

  • How do I get public feed from facebook without user authentication on a native/Desktop app?

    - by KronoS
    I'm looking to get publicly available facebook feeds (i.e. Google's facebook page/posts). However instead of forcing the user to sign into their own facebook app, I want to be able to access these posts. I've looked into using "App Access Tokens" however since my application is a native/Desktop app (iOS, Android, WP8/Win 8) I'm not able to do this. Is there a way to get publicly accessible feeds from facebook without user authentication? I'm using the Facebook C# SDK to access facebook. Currently I'm doing the following: dynamic tokenInfo = fb.Get( String.Format( "/oauth/access_token?client_id={0}&client_secret={1}&grant_type=client_credentials", FbController.AppId, FbController.AppSecret)); var appAccessToken = (string) tokenInfo.access_token; fb = new FacebookClient(); dynamic response = fb.Get( String.Format( "/google/posts?access_token={0}", appAccessToken)); Problem is that this only works if my application is set to "web" instead of "native/Desktop". I get the following error when running this code and classified app as native/Desktop. (OAuthException - #15) (#15) Requires session when calling from a desktop app

Been trying to find the cause for the past 2 days but am totally stumped!! Any help will be greatly appreciated!!!! Thanks!! Roland
