• DDD: Where to create entity objects?

  - by ciscoheat

  I have three entities that must interact: User, SupportTicketand PhoneConversation. When someone calls in requesting help, the User should have a SupportTicket assigned to him, with a PhoneConversation assigned to the Ticked describing the call. My question is: In what entity should I put the method CreatePhoneSupportTicket() that creates a new SupportTicket and a PhoneConversation, relates them to each other and finally relates the SupportTicket to the User? I'm guessing it can't be on the user because that would violate the SRP (the user does a few more things). But the method itself does more than one thing, it should create both a SupportTicket and a PhoneConversation. Is this a situation when a Service is a better solution then putting methods on entities? Thanks for your help!

Don’t worry about the code in PHP script.

• Decorator Design Pattern Use With Service Objects (wSingleton)

  - by Dustin

  I'm working on a project where I need to add some functionality to a service object and using a decorator to add it in seems like a good fit. However, I've only ever used decorators with simple beans, never on a singleton like a service object. Has anyone ever done this before and what are the pros and cons? In this case I don't think creating a subclass will work so a decorator seems to be a good fit. What are your thoughts on doing this?

• How to select all ActiveX objects in an area using a mouse in Excel?

  - by enderland

  Because of this problem with ActiveX objects changing size, I am not grouping my ActiveX objects in my Excel worksheet. Grouping them causes my solution hack to not work which is quite annoying. However, I often times want to be able to essentially use the mouse and select a region and then select all ActiveX objects contained in the region. This would also be useful for easily selecting objects to group them initially. Basically: Use mouse to select area Automatically select all ActiveX components in region I'm fine with a VBA solution if needed. How can I do this?

• SubSonic Change DropDown Value for Load Drops SUB

  - by GTJR

  I used the subsonic generator to create some aspx pages, It works fine. On some of the pages it automaticaly generated the dropdown boxes for foreign key values. How Can change that value in the load drops code? Or where I need to change it. For instance I have a workers table and a workersweek table. The workers table has a workerid,firstname and lastname field and the workersweek has a workerID field. The generator automatically set it up to show the firstname in the dropdown. I want to change the value to be both firstname and lastname. I am sure I will have to add code that does something like firstname + " " + Lastname. I am just not sure where to do it withing the code that was generated. I see the load drops sub, but it does not seem like that is the one I need to modify.

• Mock Objects properties not changing

  - by frictionlesspulley

  I am new to using Mock test in .Net. I am testing out a financial transaction which is of the following nature: int amt =20; //sets all the props and func and returns a FinaceAccount. //Note I did not SetUp the amt of the account. var account =GetFinanceAccount() //service layer to be tested _financeService.tranx(account,amt); //checks if the amt was added to the account.amt //here the amt comes out same as that set in GetFinanceAccount. Assert.AreEqual(account.amt ,amt) I know that the function tranx works correctly but there is an issue with the test. Are there any GOOD reference material on Mocking in .Net

• Passing derived objects in a constructure

  - by Clarence Klopfstein

  This is a bit of a convoluted question, hopefully I can make it clear. I am finding that this may not be possible, but am trying to see if anybody has a solution. I have four classes, two are core classes and two are those core classes extended: extUser Extends coreUser extSecurity Extends coreSecurity In the constructor for coreUser you have this: public coreUser(string id, ref coreSecurity cs) When trying to extend coreUser you would have this: public extUser(string id ref extSecurity es) : base(id, ref es) This fails because es is of type, extSecurity and the base class expects a type of coreSecurity. I've not found anyway to cast this to allow for me to override this base class in C#. In VB it works just fine. Ideas?

• jQuery and array of objects

  - by sepoto

  $(document).ready(function () { output = ""; $.ajax({ url: 'getevents.php', data: { ufirstname: 'ufirstname' }, type: 'post', success: function (output) { alert(output); var date = new Date(); var d = date.getDate(); var m = date.getMonth(); var y = date.getFullYear(); $('#calendar').fullCalendar({ header: { left: 'prev,next today', center: 'title', right: 'month,basicWeek,basicDay' }, editable: true, events: output }); } }); }); I have code like this and if I copy the text verbatim out of my alert box and replace events: output with events: [{ id: 1, title: 'Birthday', start: new Date(1355011200*1000), end: new Date(1355011200*1000), allDay: true, url: 'http://www.yahoo.com/'},{ id: 2, title: 'Birthday Hangover', start: new Date(1355097600*1000), end: new Date(1355097600*1000), allDay: false, url: 'http://www.yahoo.com'},{ id: 3, title: 'Sepotomus Maximus Christmas', start: new Date(1356393600*1000), end: new Date(1356393600*1000), allDay: false, url: 'http://www.yahoo.com/'},] Everything works just fine. What can I do to fix this problem? I though that using events: output would place the text in that location but it does not seem to be working. Thank you all kindly in advance for any comments or answers!

• Framework for creating mock objects in Java

  - by Amir Rachum

  This is NOT a question about which is the best framework, etc. I have never used a mocking framework and I'm a bit puzzled by the idea. How does it know how to create the mock object? Is it done in runtime or generates a file? How do you know its behavior? And most importantly - what is the work flow of using such a framework (what is the step-by-step for creating a test). Can anyone explain? You can choose whichever framework you like for example, just say what it is.

• Split cell value into multiple cells

  - by wilhelmtell

  How do I get Excel to split a sequence of delimited values in a cell over multiple cells? | A | B 1| 1 2 4 | 2| | Split over /\s+/: | A | B 1| 1 | 2| 2 | 3| 4 | This is in a pivot table, so I want the pivot table's mechanism to take the split in account, and consider it as if the data came this way from the datasource.

• I need a dictionary-like mapping between characters and other kinds of objects. Which class would be

  - by nullPointerException

  This is in Squeak/Pharo. If I want to have a mapping between Character objects like $a and $b to other kinds of objects, and want to look up those other objects based on the Character, what is the best class to use? Dictionary is an obvious choice, but seems wasteful to be hashing character objects which are basically already numbers. I guess what I want is a kind of array where the character value (number) is used as an index/offset, but I am not sure if this is possible with Unicode.

• Comparison of IPEndPoint objects not working

  - by Martin Mizzell

  I have an IPEndPoint a and b, whose IPAddress and Port are exactly the same, but the == operator is on the IPEndPoint not returning true. To make things even stranger, I tried to circumvent the problem by simply comparing the IPAddress and Port individually and it is STILL not returning true. Has anyone encountered this before? If so, I am all ears to performant solutions. We have collections of as many as 10k IPEndPoints and are querying into them via LINQ (PLINQ pretty soon).

• How do games move around objects (in general) (OGL)

  - by user146780

  I'm sure there's not just 1 answer to this but, do game engines actually change the vectors in memory, or use gltransformations? Because pushing and popping the matrix all the time seems inefficient, but if you keep modifying the verticies you cant make use of display lists. So I'm wondering how it's done in general. Thanks

• C#, Using Custom Generic Collection faster with objects than List

  - by Kaminari

  Hello, I'm using for now List< to iterate through some object collection and find matching element, The problem is that object has only 2 significant values Name and Link (strings) but has some other values wich I dont want to compare. I'm thinkig about using something like HashSet (wich is exactly what I'm searching for - fast) from .NET 3.5 but target framework has to be 2.0. There is something called Power Collections here: http://powercollections.codeplex.com/ But maybe there is other way? If not, can you suggest me a suitable custom collection?

• C++ Access variable value using string representing variable's name

  - by Paul Ridgway

  Hello everyone, If the title was not clear, I will try to clarify what I am asking: Imagine I have a variable called counter, I know I can see its current value by doing something like: std::cout << counter << std::endl; However, assume I have lots of variables and I don't know which I'm going to want to look at until runtime. Does anyone know a way I can fetch the value of a variable by using its name, for example: std::cout << valueOf("counter") << std::endl; I feel being able to do this might make debugging large complex projects easier. Thanks in advance for your time. PS: Please do not respond with 'Google it', I have, though maybe not with the best query to get the answer I'm looking for...

• Performance of Serialized Objects in C++

  - by jm1234567890

  Hi Everyone, I'm wondering if there is a fast way to dump an STL set to disk and then read it back later. The internal structure of a set is a binary tree, so if I serialize it naively, when I read it back the program will have to go though the process of inserting each element again. I think this is slow even if it is read back in correct order, correct me if I am wrong. Is there a way to "dump" the memory containing the set into disk and then read it back later? That is, keep everything in binary format, thus avoiding the re-insertion. Do the boost serialization tools do this? Thanks! EDIT: oh I should probably read, http://www.parashift.com/c++-faq-lite/serialization.html I will read it now... no it doesn't really help

  I have an image uploading script in which i use the following setup to assign names to uploaded images; $saltdate = date( 'U' ); $saltuser = $_SERVER[REMOTE_ADDR]; $saltname = md5($saltdate.$saltuser); // Recieve, Process, Save uploaded image // Update database with image name The problem that i encounter is that after processing/saving the image, when its time to add this file name to the database, the value of $saltdate seems to have changed and i will get a file name in the database that doesnt exist. How can i make sure that the value doesn't change once i establish it?
