• Transparently storing class state without exposing implementation

  - by RoToRa

  I have a model (MVC) class whose internal state (which basically contains of private int fields) I want to store. The program is running on Android (for now) so I need to store the in a Bundle, but I'll be using the same class later in a desktop application where I'll have to store the state some other way, so I can't reference Bundle directly in my class. So my question is: What is the best way to store (and retrieve) the state of a class without exposing it's implementation? The best I could think of removing the private access modifier so that the fields become package accessible and create read/write helper classes in the same package, but that somehow seems wrong.

• References/walkthroughs for maintaining database schemas with Visual Studio 2010?

  - by user206356

  I have Visual Studio 2010 Beta 2 and SQL Server 2008 installed. I'm working with a populated database and want to modify various column types. SQL Server Management Studio requires me to drop tables to do this, and get pretty finicky given my moderate level of knowledge of SQL Server. However, I heard the new database project type supports changing the database schema to the desired format and it will handle creating and running all the scripts to implement the changes. I've created a VS2010 database project using the existing database as the source, but so far haven't had much luck figuring out the appropriate method to make the changes without getting an error. As a result, I'm looking for any reference info I can find on using VS2010's capabilities in this area. Any suggestions?

• Why is std::tr1::shared_ptr<>.reset() so expensive?

  - by Paul Oyster

  Profiling some code that heavily uses shared_ptrs, I discovered that reset() was surprisingly expensive. For example: struct Test { int i; Test() { this->i = 0; } Test(int i) { this->i = i; } } ; ... auto t = make_shared<Test>(1); ... t.reset(somePointerToATestObject); Tracing the reset() in the last line (under VC++ 2010), I discovered that it creates a new reference-counting object. Is there a cheaper way, that reuses the existing ref-count and does not bother the heap?

• How to return settings from an object

  - by Rockbot

  i have done something like this: myProject = settings: duration: 500 value: 'aValue' aFunction: -> myElement.fadeOut myProject.settings.duration This is just a sample but my project is like that. A lot of times i have to reference to the settings to get a certain value, and i always have to write myProject.settings.value, and it doesn´t look good. My question is, can I call a function that returns the wanted value? Something like this? aFunction -> myElement.fadeOut getSetting(duration) I tried with getSetting: (param) -> myProject.settings.param but failed? Why is that? Thank you!

• C# overloading with generics: bug or feature?

  - by TN

  Let's have a following simplified example: void Foo<T>(IEnumerable<T> collection, params T[] items) { // ... } void Foo<C, T>(C collection, T item) where C : ICollection<T> { // ... } void Main() { Foo((IEnumerable<int>)new[] { 1 }, 2); } Compiler says: The type 'System.Collections.Generic.IEnumerable' cannot be used as type parameter 'C' in the generic type or method 'UserQuery.Foo(C, T)'. There is no implicit reference conversion from 'System.Collections.Generic.IEnumerable' to 'System.Collections.Generic.ICollection'. If I change Main to: void Main() { Foo<int>((IEnumerable<int>)new[] { 1 }, 2); } It will work ok. Why compiler does not choose the right overload?

• How do I manipulate a tree of immutable objects?

  - by Frederik

  I'm building an entire application out of immutable objects so that multi-threading and undo become easier to implement. I'm using the Google Collections Library which provides immutable versions of Map, List, and Set. My application model looks like a tree: Scene is a top-level object that contains a reference to a root Node. Each Node can contain child Nodes and Ports. An object graph might look like this: Scene | +-- Node | +-- Node | +- Port +-- Node | +- Port +- Port If all of these objects are immutable, controlled by a top-level SceneController object: What is the best way to construct this hierarchy? How would I replace an object that is arbitrarily deep in the object tree? Is there a way to support back-links, e.g. a Node having a "parent" attribute?

• How to maintain 2 lists of object

  - by michael

  Hi, My c++ program needs to maintain 2 list of objects. list inuse; list free; So objects A can even in 'inuse' list or in 'free' list, but not both. http://www.cplusplus.com/reference/stl/list/ I am think of using 'list' as the data structure for my lists. My questions are 1. why i can't randomly access an elmenet in the list, I look at the above api, I don't see a way to get inuse[2]; 2. How can I remove an element in the list? There is an erase(), but how can I use it to remove element #2? And after I remove element 2? will STL list fill the erased spot automatically? e.g. #3 will become #2, #4 will become #3 and so on? Thank you.

• Help with SQL query

  - by user154301

  Hello, I have list of DateTime values, and for each value I need to fetch something from the database. I would like to do this with one query. I know it's possible to pass a table (list) to the stored procedure, but Im not sure how to write the query itself. Let's say I have the following table: CREATE TABLE Shows( ShowId [int] NOT NULL, StartTime DateTime NOT NULL, EndTime DateTime NOT NULL ) and an array of dates DECLARE @myDateArray MyCustomDateArrayType Now, if I were fetching a single item, I would write a query like this: SELECT * FROM Shows WHERE StartTime > @ArrayItem and @ArrayItem < EndTime where @ArrayItem is an item from @myDateArray . But how do I formulate the query that would fetch the information for all array items? Thanks!

• Comma separated values in a database field

  - by John Doe

  I have a products table. Each row in that table corresponds to a single product and it's identified by a unique Id. Now each product can have multiple "codes" associated with that product. For example: Id | Code ---------------------- 0001 | IN,ON,ME,OH 0002 | ON,VI,AC,ZO 0003 | QA,PS,OO,ME What I'm trying to do is create a stored procedure so that I can pass in a codes like "ON,ME" and have it return every product that contains the "ON" or "ME" code. Since the codes are comma separated, I don't know how I can split those and search them. Is this possible using only TSQL? Edit: It's a mission critical table. I don't have the authority to change it.

• In Drupal, can you control block display according to e.g. number of URL parts?

  - by james6848

  I'm having a little trouble controlling page-specific block display in Drupal... My URL's will be of this typical structure: http://www.mysite.co.uk/section-name/sub-page/sub-sub-page The 'section-name' will effectively be fixed, but there will be many sub-pages (far too many to explicitly reference). I need to somehow control block display as follows: One block will show on all pages where URL contains 'section-name/sub-page' but not on pages 'section-name/sub-page/sub-sub-page' Conversely, another block will show on all pages where URL contains 'section-name/sub-page/sub-sub-page' but not on pages 'section-name/sub-page' My only idea is to do a bit of PHP that looks for the string 'section-name' and then also counts URL parts (or even the number of slashes). Not sure how to implement that though :) Your help would be appreciated!

• JAR file folder for eclipse projects

  - by Daff

  I'm trying to create a centralized folder (in some kind of a "meta project" in my eclipse workspace) for commonly used JAR files for referenced projects in this workspace. It should work similar to the WEB-INF/lib folder for web projects but also apply to non web projects, and automatically scan and add all jar files in this folder. I tried to create a user library with these jar files and reference them in the project but I still have to add every new jar manually to the user library (and don't know if it is referenced relative of absoulute) and Tomcat (WTP) doesn't seem to take these files (Run As - Run on Server) into its classpath (and I don't want to duplicate the jars and put them into WEB-INF/lib). Any ideas?

• Drupal Error After Logging In

  - by Kim

  Hello everyone. I'm kinda new to using drupal and i'm just wondering why I kind of get this error on my new site. See i have this website under WampServer running drupal6-16. Everytime I log in with my pre-created admin account 'admin01' pass: 'admin01' i get redirected to the WampServer localhost which appears to be unusual since the header does not have the WampServer logo. I already tried creating a new drupal website with the same database and the same thing happens. Also, I tried creating another website with a new database but I copied the other website's theme and other contents and the same thing happens. Help me please. I am losing my grip on this. :( Note: I have the same website running on one PC and i am just trying to run it on another PC by copying all its contents. The original copy is working perfectly but I can't seem to get the hook on my new copies to work on other PCs.

• Auto Re-Running of Tests that fail

  - by Tangopop

  I have a set of Selenium/MbUnit Tests that work fine, but tend to take a while to run (over 4 hours) A problem i am finding is that about 1 in 20 test seems to timeout when running. I have confirmed the Selenium GRID is working and the Selenium RC's are all fine, it just seems to be a qwerk of the system. What is really annoying though is that if i run these tests again they will usually pass. What i want to know is if there is a way for me to auto rerun the tests (probably in the code) if a perticular type of exception is caught... I have attempted to put a few lines of code in the catch statement but i know this is a very hacky way of re running the tests. Here is the code: catch (AssertionException e) { if (e.Message() == "TimeOut") //Something similar to this { this.Test(); } else { verificationErrors.AppendLine(browserList[i] + " :: " + e.Message); } } Any suggestions?

• Delphi : What is the best way for passing data between forms?

  - by Flom Enol

  It may seem a little newbie, but I really have got problem with it. I have a form (not the main one)for getting many different data form the user and I want to pass it to a manager class for creating an object with these. The problem is that I can't have this class to use the other unit (getting circle uses) and also it doesn't have access to the manager class instance (which is in main form). So, what shall I do? I've already considered using public variable but I have a bad feeling about it (regarding OOD patterns). Any ideas? thanks in advance.

• [c++] Resolving namespace conflicts

  I've got a namespace with a ton of symbols I use, but I want to overwrite one of them: external_library.h namespace lottaStuff { class LotsOfClasses {}; class OneMoreClass {}; }; my_file.h using namespace lottaStuff; namespace myCustomizations { class OneMoreClass {}; }; my_file.cpp using myCustomizations::OneMoreClass; int main() { OneMoreClass foo; // error: reference to 'OneMoreClass' is ambiguous return 0; } How do I get resolve the 'ambiguous' error without resorting to replacing 'using namespace lottaStuff' with a thousand individual "using xxx;" statements?

• Response Time is different for mulitiple execution of the application with the same request Performa

  - by sivananda

  My java application functionality is to provide reference data (basically loads lots of data from xml files into hashmap) and hence we request for one such data from the hashmap based on a id and we have such multiple has map for different set of business data. The problem is that when i tried executing the java application for the same request multiple times, the response times are different like 31ms, 48ms, 72ms, 120ms, 63ms etc. hence there is a considerable gap between the min and max time taken for the execution to complete. Ideally, i would expect the response times to be like, 63ms, 65ms, 61ms, 70ms, 61ms, but in my case the variation of the response time for the same request is varying hugely. I had used a opensource profile to understand if there is any extra execution of the methods or memory leak, but as per my understanding there was no problem. Please let me know what could be the reasons and how can i address this problem.

• Entity framework Update fails when object is linked to a missing child

  - by McKay

  I’m having trouble updating an objects child when the object has a reference to a nonexising child record. eg. Tables Car and CarColor have a relationship. Car.CarColorId CarColor.CarColorId If I load the car with its color record like so this var result = from x in database.Car.Include("CarColor") where x.CarId = 5 select x; I'll get back the Car object and it’s Color object. Now suppose that some time ago a CarColor had been deleted but the Car record in question still contains the CarColorId value. So when I run the query the Color object is null because the CarColor record didn’t exist. My problem here is that when I attach another Color object that does exist I get a Store update, insert error when saving. Car.Color = newColor Database.SaveChanges(); It’s like the context is trying to delete the nonexisting color. How can I get around this?

• Passing NULL values into mysql Stored procedure

  - by McNabbToSkins

  I am trying to pass a few NULL values to a stroed procedure but PHP always retains the varaibles to be empty strings '' and not NULL. My DB insert function looks like this. (I am using a Framework and ADODB so if it looks weird thats why). function insert_emp($f_name, $last_name, $dob) { if(!isset($dob)){ $dob = NULL; } $this->DB->setConnection("CALL insert_emp('$f_name', '$l_name', '$dob')"); } I have ensured that $dob is being passed an empty string ''. But for some reason when it calls the stored proc it is not changed to NULL. dob is a datetime field and mysql complains that you can not enter an empty string as a DATETIME. If I hard code the insert such as this $this->DB->setConnection("CALL insert_emp('Test1', 'Test2', 'NULL')"); it will work. Thanks for the help.

• SQL Server 2008 - Conditional Query

  - by Villager

  Hello, SQL is not one of my strong suits. I have a SQL Server 2008 database. This database has a stored procedure that takes in eight int parameters. For the sake of keeping this question focused, I will use one of these parameters for reference: @isActive int Each of these int parameters will be -1, 0, or 1. -1 means "Unknown" or "Don't Care". Basically, I need to query a table such that if the int parameter is NOT -1, I need to consider it in my WHERE clause. Because there are eight int parameters, an IF-ELSE statement does not seem like a good idea. At the same time, I do not know how else to do this? Is there an elegant way in SQL to add a WHERE conditional if a parameter does NOT equal a value? Thank you!

• Can Django flush its database(s) between every unit test

  - by mikem

  Django (1.2 beta) will reset the database(s) between every test that runs, meaning each test runs on an empty DB. However, the database(s) are not flushed. One of the effects of flushing the database is the auto_increment counters are reset. Consider a test which pulls data out of the database by primary key: class ChangeLogTest(django.test.TestCase): def test_one(self): do_something_which_creates_two_log_entries() log = LogEntry.objects.get(id=1) assert_log_entry_correct(log) log = LogEntry.objects.get(id=2) assert_log_entry_correct(log) This will pass because only two log entries were ever created. However, if another test is added to ChangeLogTest and it happens to run before test_one, the primary keys of the log entries are no longer 1 and 2, they might be 2 and 3. Now test_one fails. This is actually a two part question: Is it possible to force ./manage.py test to flush the database between each test case? Since Django doesn't flush the DB between each test by default, maybe there is a good reason. Does anyone know?

• PowerPoint API, how to change slide layout programmatically

  - by 112811688864492097861

  Hello, I'm working on PowerPoint Add-In and I was faced with trouble I couldn't solve myself. The point is I need to change the slide Layout programmaticaly with C# (the Add-In Express 2009 for Office and .NET is used). If the new layout is a predefined one everything is fine but I need to set a custom layout as a new one (without slide recreating). Unfortunately, I didn't find any information on how to do it, PowerPoint object model reference documentation didn't answer me as well. There is just the ability to create a new slide that uses custom layout. I've done an experiment seria and have ensured that the Slide object stayed being the same while I have been changing layout both predefined and custom ones. I don't want to create a new slide when I need just switch the layout. Is it possible at all? Please help me to find a way of doing it. Thanks in advance.
