  • Exception Handling in SQl Stored Procedures?

    - by Rishabh Ohri
    Hi All, Adding Exceptional Handling is a good practise, but I have a doubt, In our database we have 10 SPs which are accessed by our data access layer, there is not much logic and the queries are also not big.The purpose of keeping the queries in SPs was to allow paged data to be easily passed to the presentation layer. So, my question is, should error handling be added to the SPs in this scenario when they do not include large complex queries?

  • How do I make multi-page landscape tables in LaTeX

    - by Tim
    The title is pretty much the extent of my question. I am trying to insert a large table into a document using the xtabular environment. If I wrap the xtabular environment in a landscape environment, then the bottom of my table gets chopped off. Does anyone have any better suggestions? Thanks \begin{landscape} \singlespace \begin{xtabular}{|c|c|c|c|c|} \hline some & stuff & ... & \\ \end{xtabular} \end{landscape} Tim

  • How to fine tune a Membership Provider?

    - by Venemo
    After all the answers to my last question about fine-tuning turned out to be more useful than I expected, I thought that I would ask another similar Question about the MembershipProviders as well. Okay, so firstly, to clarify: I know what a Membership, Role, and Profile provider is, how to implement my own, and how to configure them, and most of the things about them. Implementing a role and profile provider is pretty straightforward, because they only require simple CRUD most of the time. (A single line of LINQ is enough for about half of the RoleProvider's methods.) However, the Membership provider is a differend beast. Many of you may realize that it violates the SR (Single Responsibility) principle, because it has to do EVERYTHING related to user management. While this leaves a lot of room for customizations, it has its downsides as well. There is no information on the Internet about what their EXACT expected behaviour is, such as when should they throw exceptions or simply return null, and stuff like that. I use this sample implementation for reference, but it also contains several contradictions. For example, it uses its own ValidateUser method for checking for credentials in the ChangePassword method. But the ValidateUser also updates the user's LastLoginDate to the current date. So, does the framework expect that I set it in my own provider as well, or is it simply a mistake in the sample? The other is: the ChangePassword method throws an exception every time when validating the new password, but CreateUser doesn't ever throw an exception, it simply returns false. And last, but not least: it counts the invalid password attempts of the user and locks them if it passes a threshold. While this is good, but it requires manual action to unlock the users. Is it a problem if my provider automatically unlocks the user after a certain amount of time? (EDIT) I almost forgot: the CreateUser method in the sample inserts the ID from the method parameter. I actually think this is bad practice, because I use inters with auto incement as IDs, so inserting them from some method parameter is not an option. Should I just ignore the parameter, or require that its value is null and throw an exception if it isn't? All in all, does ASP.NET have any assumptions about the behaviour of a MembershipProvider? Is there any documentation which describes when should I throw an exception or just return null? I also tried to find a set of generic unit tests which would provide some guidance about the expected behaviour, but no luck, I found plenty of articles about "Unit testing is good", and "How to unit test a MembershipProvider", but not one where there would be any actual tests. Thanks in advance for everyone!

  • Singleton class in DLL used on multiple virtual directories

    - by Drejc
    I have the following situation: multiple virtual directories under same application pool in IIS copy of same DLL in all those directories (same version number) a singleton class in one in this DLL The question is, is this singleton class created only once for all those Virtual Directory instances or is there for each of there one singleton class. The code looks something like this: [ Transaction(TransactionOption.Supported), ClassInterface(ClassInterfaceType.AutoDispatch), Guid("7DE45C4D-19BE-4AA4-A2DA-F4D86E6502A8") ] public class SomeClass { private static readonly Singleton singleton = new Singleton();

  • Coming Up with a Good Algorithm for a Simple Idea

    - by mkoryak
    I need to come up with an algorithm that does the following: Lets say you have an array of positive numbers (e.g. [1,3,7,0,0,9]) and you know beforehand their sum is 20. You want to abstract some average amount from each number such that the new sum would be less by 7. To do so, you must follow these rules: you can only subtract integers the resulting array must not have any negative values you can not make any changes to the indices of the buckets. The more uniformly the subtraction is distributed over the array the better. Here is my attempt at an algorithm in JavaScript + underscore (which will probably make it n^2): function distributeSubtraction(array, goal){ var sum = _.reduce(arr, function(x, y) { return x + y; }, 0); if(goal < sum){ while(goal < sum && goal > 0){ var less = ~~(goal / _.filter(arr, _.identity).length); //length of array without 0s arr = _.map(arr, function(val){ if(less > 0){ return (less < val) ? val - less : val; //not ideal, im skipping some! } else { if(goal > 0){ //again not ideal. giving preference to start of array if(val > 0) { goal--; return val - 1; } } else { return val; } } }); if(goal > 0){ var newSum = _.reduce(arr, function(x, y) { return x + y; }, 0); goal -= sum - newSum; sum = newSum; } else { return arr; } } } else if(goal == sum) { return _.map(arr, function(){ return 0; }); } else { return arr; } } var goal = 7; var arr = [1,3,7,0,0,9]; var newArray = distributeSubtraction(arr, goal); //returned: [0, 1, 5, 0, 0, 7]; Well, that works but there must be a better way! I imagine the run time of this thing will be terrible with bigger arrays and bigger numbers. edit: I want to clarify that this question is purely academic. Think of it like an interview question where you whiteboard something and the interviewer asks you how your algorithm would behave on a different type of a dataset.

  • SVG to Android Shape

    - by Buggieboy
    I have started learning about vector drawing in Android with the Shape class. Since Shape is a Drawable, and Drawables are usually defined as XML, it sounds a lot like the vector drawing commands in SVG. My question is this: Has anybody created an XSLT transformation, or other mechanism, for converting an SVG drawing description into Android Shapes?

  • Efficient code to avoid circular references in c# object model

    - by Kumar
    I have an excel like grid where values can be typed referencing other rows To check for circular references when a new value is entered, i traverse the tree and create a list of values referenced thus far, if the current value is found in this list, i return an error thus avoiding a circular reference. This is infrequent enough where extreme performance is not an issue but... Question - is there a better way ? I'm told it's not the most optimal but no answer was provided so on to the experts @ SO :)

  • ASP.NET AJAX Partial Rendering

    - by AJ
    Hello, I have a question about how ASP.NET AJAX partial rendering actually works. Does it: 1) Renders the whole page on the server, transmits the whole page to the client, the client then merges just the area contained in the update panel. 2) Renders the whole page on the server, transmits and merges just the area contained by the update panel. 3) Renders, transmits and merges just the area contained by the update panel. Thanks, AJ

  • Why are there so many Database Management Systems?

    - by mr.bio
    Why are there so many Database management systems? I am not an DB expert and I've never thought about using another Database other than mySQL. Programming languages offer different paradigms, so it makes sense to choose a specific language for your purpose. Question What are the factors in choosing a specific Database management system ?

  • Reloading of persisted entity

    - by Udi
    I'm using OpenJPA in my application as a JPA vendor. The question is theoretical or conceptual: Is there any way to tell an entity manager to load an entity from the DB rather than from it's cache? The problematic scenario: EM1.persist(Entity1) EM2.merge(Entity1) EM1.find(Entity1) <--- Entity1 is the cached version rather than the merged one.. Any elegant way to do it? I really don't want to call em.refresh(entity).

  • How to scroll text in Python/Curses subwindow?

    - by lecodesportif
    In my Python script which uses Curses, I have a subwin to which some text is assigned. Because the text length may be longer than the window size, the text should be scrollable. It doesn't seem that there is any CSS-"overflow" like attribute for Curses windows. The Python/Curses docs are also rather cryptic on this aspect. Does anybody here have an idea how I can code a scrollable Curses subwindow using Python and actually scroll through it? \edit: more precise question

  • Why is Microsoft not developing a Halo-like next gen title using C#? [closed]

    - by Joan Venge
    The question might look subjective but considering Microsoft: Owns the Xbox 360 platform Owns the Windows platform Have their own game studio (MGS) Own other 3rd party developers Is a major publisher makes me wonder why Microsoft doesn't push their flagship language to prove that not only you can cut down significant development time, and therefore money, but also show that you can release a next gen title where the real time interactivity doesn't suffer. If Microsoft were to do this once, I am sure many AAA developers would jump on that wagon too.

    - by Freewind
    In my partial template, there is a varible named "resource", it may be a question or an answer. I want to build a link to edit it, but when I use it, I don't know what it is, so I can't write: <%=link_to 'edit', edit_question_url(resource)%> or <%=link_to 'edit', edit_answer_url(resource)%> I wonder if there is such a method, say "url_for_edit()", can be used as: <%=link_to 'edit', url_for_edit(resource)%> Is there such a method?
