  • Determine if an Index has been used as a hint

    - by Joe Bloggs
    In SQL Server, there is the option to use query hints. eg SELECT c.ContactID FROM Person.Contact c WITH (INDEX(AK_Contact_rowguid)) I am in the process of getting rid of unused indexes and was wondering how I could go about determining if an index was used as a query hint. Does anyone have suggestions on how I could do this? Cheers, Joe

  • auto indent in vim string replacement new line?

    - by rxin
    I'm using the following command to auto replace some code (adding a new code segment after an existing segment) %s/my_pattern/\0, \r some_other_text_i_want_to_insert/ The problem is that with the \r, some_other_text_i_want_to_insert gets inserted right after the new line: mycode( some_random_text my_pattern ) would become mycode( some_random_text my_pattern some_other_text_i_want_to_insert <--- this line is NOT indented ) instead of mycode( some_random_text my_pattern some_other_text_i_want_to_insert <--- this line is now indented ) i.e. the new inserted line is not indented. Is there any option in vim or trick that I can make the newly inserted line indented? Thanks.

  • IQueryable and lazy loading

    - by Nelson
    I'm having a hard time determining the best way to handle this... With Entity Framework (and L2S), LINQ queries return IQueryable. I have read various opinions on whether the DAL/BLL should return IQueryable, IEnumerable or IList. Assuming we go with IList, then the query is run immediately and that control is not passed on to the next layer. This makes it easier to unit test, etc. You lose the ability to refine the query at higher levels, but you could simply create another method that allows you to refine the query and still return IList. And there are many more pros/cons. So far so good. Now comes Entity Framework and lazy loading. I am using POCO objects with proxies in .NET 4/VS 2010. In the presentation layer I do: foreach (Order order in bll.GetOrders()) { foreach (OrderLine orderLine in order.OrderLines) { // Do something } } In this case, GetOrders() returns IList so it executes immediately before returning to the PL. But in the next foreach, you have lazy loading which executes multiple SQL queries as it gets all the OrderLines. So basically, the PL is running SQL queries "on demand" in the wrong layer. Is there any sensible way to avoid this? I could turn lazy loading off, but then what's the point of having this "feature" that everyone was complaining EF1 didn't have? And I'll admit it is very useful in many scenarios. So I see several options: Somehow remove all associations in the entities and add methods to return them. This goes against the default EF behavior/code generation and makes it harder to do some composite (multiple entity) LINQ queries. It seems like a step backwards. I vote no. If we have lazy loading anyway which makes it hard to unit test, then go all the way and return IQueryable. You'll have more control farther up the layers. I still don't think this is a good option because IQueryable ties you to L2S, L2E, or your own full implementation of IQueryable. Lazy loading may run queries "on demand", but doesn't tie you to any specific interface. I vote no. Turn off lazy loading. You'll have to handle your associations manually. This could be with eager loading's .Include(). I vote yes in some specific cases. Keep IList and lazy loading. I vote yes in many cases, only due to the troubles with the others. Any other options or suggestions? I haven't found an option that really convinces me.

  • Adding a mini admin to a webpage.

    - by DADU
    Hello Picture this: you are creating a little module that people can incorporate into their website easily, for example, a little contact form. It would consist of a PHP file that outputs some HTML, a Javascript file (ajax etc.), a CSS file and a CSS skin. Now the person who doesn't know much about coding wants to integrate it on a webpage (website/index.php). We could do this with three rules of code: <link rel="stylesheet" href="module/css/module.css" /> <script src="module/js/module.js"></script> <?php require_once 'module/module.php'; ?> There's no doubt this part is questionable, right? Now when we want to add an admin for this little module, there are two options: Accessing the admin via an extra URL like website/module/admin.php and after authentication, displaying a page where the person can do all the settings. The person then goes back to index.php to see the results. Enabling the admin via an extra URL like website/module/admin.php and after authentication, redirecting back to index.php. The person can now edit the module directly (HTML5 contenteditable) and see changes live, on the webpage where everybody else will see it when the person saves the changes. Option 2 has a couple of advantages: The person doesn't have to toggle between admin and index.php. The person can see directly how it's looking at the webpage it's integrated in. The person probably feels like the module is more part of the webpage/website. Of course option 2 has some disadvantages too: Not everything works well editing it inline. The person would need to have an HTML5 compliant browser. Probably some more I can't think of right now. Now I have a few concerns that's I can't seem to see a clear answer to. How would we let the person integrate the admin on their webpage? The admin files only need to be included in index.php if the person has choosen to edit the module via the url (website/module/admin.php). But how can we do this if we have a admin.css file that belongs in the head section, an admin.php file that goes into the body, and another admin.js file that's included at the end of the body? How would we know the file that admin.php needs to redirect back to, after authentication? index.php could be any webpage with any name. Any real life website/web apps examples using this principle are welcome too. If there's something unclear, I am glad to add additional info.

  • Troubles with list "dropdowns" and which list item gets the dropdown

    - by Andrew
    I'm working on a project for an MMO "guild" that gives members of the guild randomly generated tasks for the game. They can "block" three tasks from being assigned. The lists will look something like this: <ul> <li class="blocked">Task that is blocked</li> <li class="blocked-open">Click to block a task</li> <li class="blocked-open">Click to block a task</li> </ul> The blocked-open class means they haven't chosen a task to block yet. The blocked task means they've already blocked a task. When they click the list item, I want this to appear: <ul class="tasks-dropdown no-display"> <li><h1>Click a Task to Block</h1></li> <ul class="task-dropdown-inner"> <?php //output all tasks foreach($tasks as $task) { echo '<li class="blocked-option"><span id="'.$task.'">'.$task.'</span></li>'; } ?> <br class="clear" /> </ul> </ul> I don't quite know how, when the user clicks the .blocked-open line-item, to show that dropdown under only the one they clicked. My jQuery looked like this before I became confused. $("li.blocked-open").click(function() { $("ul.no-display").slideToggle("900"); }); $(".blocked-option span").click(function() { var task = $(this).attr('id'); alert("You have blocked: " + task); location.reload(true); }); I tested it by putting the dropdown under a line item in the code, and it worked fine, but when I have more than one dropdown in the code, clicking on one line item toggles all the dropdowns. I'm not sure what to do. :-p.

  • ASP.NET MVC 2 AJAX dilemma: Lose Models concept or create unmanageable JavaScript

    - by Slightly Frustrated
    Hi, Ok, let's assume we are working with ASP.NET MVC 2 (latest and greatest preview) and we want to create AJAX user interface with jQuery. So what are our real options here? Option 1 - Pass Json from the Controller to the view, and then the view submits Json back to the controller. This means (in the order given): User opens some View (let's say - /Invoices/January) which has to visualize a list of data (e.g. <IEnumerable<X.Y.Z.Models.Invoice>>) Controller retrieves the Model from the repository (assuming we are using repository pattern). Controller creates a new instance of a class which we will serialize to Json. The reasaon we do this, is because the model may not be serializable (circular reference ftl) Controller populates the soon-to-be-serialized class with data Controller serializes the class to Json and passes it the view. User does some change and submits the 'form' The View submits back Json to the controller The Controller now must 'manually' validate the input, because the Json passed does not bind to a Model See, if our View is communicating to the controller via Json, we lose the Model validation, which IMHO is incredible disadvantage. In this case, forget about data annotations and stuff. Option 2 - Ok, the alternative of the first approach is to pass the Models to the Views, which is the default behavior in the template when you start a new project. We pass a strong typed model to the view The view renders the appropriate html and javascript, sticking to the model property names. This is important! The user submits the form. If we stick to the model names, when we .serialize() the form and submit it to the controller it will map to a model. There is no Json mapping. The submitted form directly binds to a strongly typed model, hence, we can use the model validation. E.g. we keep the business logic where it should be. Problem with this approach is, if we refactor some of the Models (change property names, types, etc), the javascript we wrote would become invalid. We will have to manually refactor the scripting and hope we don't miss something. There is no way you can test it either. Ok, the question is - how to write an AJAX front end, which keeps the business logic validation in the model (e.g. controller passes and receives a Model type), but in the same time doesn't screw up the javascript and html when we refactor the model?

  • How do I allow users to dial numbers in my tableView cells?

    - by Griffo
    Hi all, I have a table containing cells with phone numbers. How can I allow the user to dial these numbers by tapping the row? It's not working by default and there's no option in interface builder like there is for uiwebviews so I imagine I need to programmatically tell the app to dial the number when the cell is tapped.

  • How to parse an argument without a name with Ruby's optparse

    - by Leonid Shevtsov
    I need to parse a command line like script.rb <mandatory filename> [options] with optparse. Sure I can write some custom code to handle the filename, then pass ARGV to optparse, but maybe there's a simpler way to do it? EDIT: there's another hacky way to parse such a command line, and that is pass '--mandatory-filename ' + ARGV to optparse, then handle the --mandatory-filename option.

  • taglib with constants functionality?

    - by jack
    I need to use some constants in my JSP. Now I'd like to use this without using scriptlets. (and adding getters is not an option, it's an external jar) Using the search I've seen that some people put them in a map. However I've seen that there's a constants function in the unstandard taglib but that is a few years old and so far I haven't found a maven repository with it. So are there any other taglibs with this functionality?

    How do I set Environment Variables in Visual Studio 2010? I found this web page: http://msdn.microsoft.com/en-us/library/ee479070.aspx Which says: From the Project menu, choose Properties. In the left pane, select Configuration Properties, and then select Environment. But when I select "Configuration Properties", there is no "Enviroment" option: http://i67.photobucket.com/albums/h292/Athono/microsoft/newstuff.jpg This is an example in VS 2008: http://i21.photobucket.com/albums/b279/GrunchCan/env.jpg But how is it done in VS 2010?

    Can anyone suggest a good implementation of a generic collection class that implements the IBindingListView & IBindingList interfaces and provides Filtering and Searching capabilities? I see my current options as: Using a class that someone else has written and tested Inheriting from BindingList, and implementing the IBindingListView interfaces Write a custom collection from scratch, implementing IBindingListView and IBindingList. Obviously, the first option is my preferred choice. Thanking you.
