  • Interpreting type codes in sys.objects in SQL Server

    - by fatcat1111
    On SQL Server, the sys.objects table includes "Type" and "Type_Desc" attributes. For example: SELECT DISTINCT [Type], Type_Desc FROM Sys.Objects ORDER BY [Type] Returns: C CHECK_CONSTRAINT D DEFAULT_CONSTRAINT F FOREIGN_KEY_CONSTRAINT FN SQL_SCALAR_FUNCTION FS CLR_SCALAR_FUNCTION IT INTERNAL_TABLE P SQL_STORED_PROCEDURE PK PRIMARY_KEY_CONSTRAINT S SYSTEM_TABLE SQ SERVICE_QUEUE TR SQL_TRIGGER U USER_TABLE UQ UNIQUE_CONSTRAINT V VIEW Is there a comprehensive list of these types somewhere? There isn't a constraint on sys.objects that points me to table of these, and sys.types contains data types. I've searched SQL BOL but haven't found it. Any help would be appreciated. EDIT: Some DBs use only a subset of these types. For example, if I have a database with no views, when I query Sys.Objects as above, there are no "V" rows in the results. I am looking for a list of all possible types and descriptions used by SQL Server.

  • Quick to develop web app in Java

    - by Mike Q
    Hi all, I need to develop a basic web app very quickly (1 week) for a demo. My requirements are Java (I need to make use of existing Java libraries to access the relevant data) 2 screens One for static data view, maybe some search parameters Other for basic form entry No fancy AJAX required Ideally easy for a web designer to come in and tart it up as necessary, without having to rewrite everything My first stop was going to be to checkout Wicket as I've heard good things about it. I don't have the time right now to dive into anything heavy, which probably writes off JSF in my mind (I played with JSF1, steep learning curve which I've now slid back down). I'm happy to treat the result as throwaway so if there's a framework which starts of well but then doesn't scale up to bigger projects, that would be ok. Any suggestions appreciated on frameworks/approach.

  • Rails: How can I log all requests which take more than 4s to execute?

    - by Fedyashev Nikita
    I have a web app hosted in a cloud environment which can be expanded to multiple web-nodes to serve higher load. What I need to do is to catch this situation when we get more and more HTTP requests (assets are stored remotely). How can I do that? The problem I see from this point of view is that if we have more requests than mongrel cluster can handle then the queue will grow. And in our Rails app we can only count only after mongrel will receive the request from balancer.. Any recommendations?

  • Trying to reinvent the wheel of StackOverflow to have a good learning experience. Need some suggesti

    - by Legend
    I want to learn and am not able to do it unless I have a real "mission" to complete. SO is my favorite and I can't imagine a better experience than actually recreating it but not in ASP. I'd like to use PHP+MySQL+jQuery. So far, I have been a self-taught programmer but I would like to master one paradigm that forces you to adhere to the standards. For instance, recently, jQuery forced me to use some "rules". The plugins were supposed to be written in a particular way and that's it. When I started off, everything seemed like Greek and Latin but when I finished a very small plugin, I felt really happy because it forced me to program in a certain way. I am looking for something like this only in a larger project. I've heard a lot about MVC and all but I am confused about the various frameworks out there. Zend seems awesome but looks heavy at the same time and also requires you to have a lot more control over the web-server whereas CakePHP is a good and a fast framework that needs only little control. Do I use one of these or just write my own MVC? I have the following goals: Goals: Site should be fast - I know this depends on my coding skills but I will learn on my way. The framework itself should not slow me down) Setting up the site should not require you to use command-line - This requirement is ok during development. But some frameworks like Symphony require you to initialize certain things through command-line Should support pluggable modules - For instance, if I want to be able to use the FCK editor, I should be able to organize things in a good way. Should be possible to extend - For instance, SO is mainly a Q&A site but I should be able to logically extend it into an Idea Management System (optional but I'm curious). This goes more into code re-usability I guess. I am comfortable with MySQL so I should be done with database design etc. with some serious effort. As for PHP, I can write code on my own but haven't really used any frameworks that much. jQuery, I started off recently and love it. I would be glad if someone can guide me during these initial steps. Precisely, when designing something like SO, I have the following questions: Do I use a framework? If yes, should it be MVC? If MVC, which one is a good and a scalable one? (I'd love something like jQuery that will not die anytime soon) How do I balance the functionality? The same logic can sometimes be made server centric or client centric. (more Ajax?). Is it a good idea to make a heavy javascript site considering the recent advances on client-side JS processing? Just in case anyone is wondering, I am not interested in commercializing any of this. I need a reason to learn something :)

  • How do I post to a webservice and display the returned Response in MVC3 Razor Application?

    - by DavieDave
    I have need to call a webservice from an HTML helper extension I created (combinbation of Action and Image) and placed in the view as follows @Html.ActionImage("CallService", new { number = ViewBag.number, code = ViewBag.code, account = ViewBag.account, amount = ViewBag.amount }, "~/Content/sb_200x61.png", "Start the Process") I am making the action call and it calls the service and returns a string of the html response, but it doesn't look right. I am using the typical HttpWebRequest to do the POST Action in C# code. Here is the controller action code: public MvcHtmlString CallService(string number, string code, string account, decimal? amount) { string response = MyService.ServiceLayer.ClassName.callService(number, code, account, Convert.ToDecimal(amount); MvcHtmlString mstring = new MvcHtmlString(response); return mstring; } When it returns the string back it's looking like the all styling and js is removed. It that due to MvcHtmlString? Is there a better way to do this? Redirect somehow ?

  • My choice of fieldname for CakePHP's form helper is not working properly, why?

    - by grokker
    Hi, I'm creating an AJAX form. The problem is when I'm trying to create a input form with formhelper, my input's name attribute is not correctly renedered in the view. Here's my code: $form->input('MainAttribute.'.$i.'.SubAttribute.'.$j.'.score', array('label' => '', 'options' => $scores)); I created it that way because I want SubAttribute to be inside MainAttribute. When I inspect the HTML, the name attribute of the form is cutted of like: name="data[SuperMainAttribute]" How can I specify the name attribute to the one that I'm planning on doing? (e.g. data[MainAttribute][0][SubAttribute][0][score])

  • Official definition of CSCI (Computer Software Configuration Item)

    - by Andreas_D
    I'm looking for the most official definition of CSCI / Configuration Item - not just what it is but what we have to deliver / can expect when a contract defines subsystems which shall be developed as configuration items. I spend some time with my famous search tool and found a lot of explanations for CSCI (wikipedia, acronym directories, ...) but I haven't found a standard or a pointer to a standard (like ISO-xxx) yet which tells (1) what it is and (2) what has to be done from a QM/CM point of view. I just ask, because a contractors QM representative stated during an acceptance test, that CI only requires to not forget the CI in the configuration plan and to assign a serial number ... I expected to see some SRS, SDD, ICD, SVD, SIP, ... documents and acceptance test documentation for those subsystems...

  • Building a document server

    - by Ben
    Hey, I'm just looking for some rough guidance here on the feasibility of a project. I have say a few thousand text documents and I want to create a web based system to serve them up to users in a OS X application. It's just a tiny aside for my family's small business, so it doesn't need to be amazing at the moment, we just want to see if we can can anyone to use it. I can't believe it can be that hard to do this? -Some sort of SQL backend database to manage permissions for users? -Download through the application? -For the moment just want to view the raw text files. -If we want people to pay, how would we go about incorporating that? Sorry for the vague outline. I'm still not 100% sure on what we want. Thanks for any help.

  • In Rails, what could cause a user to have another user's session?

    - by DavidNorth
    I have a Rails application using with an authentication system using Restful Authentication without any modification. Users have reported finding themselves logged in as the wrong user. In at least one case it was on their very first page view, never having logged in before. Is it possible their session ids are getting mixed up? Would switching to CookieStore make it impossible for this to happen since no session data is stored on the server this way? I suspect the problem is related to Passenger but I don't know where to start debugging this. Its only happened about 4 times in several months of being live so its virtually impossible to reproduce. Environment: ActiveRecord session storage Rails 2.2.2 Passenger 2.0.1 Apache 2 Ruby 1.8.6 Many thanks

  • Get top 'n' records by report_id

    - by Skudd
    I have a simple view in my MSSQL database. It consists of the following fields: report_id INT ym VARCHAR -- YYYY-MM keyword VARCHAR(MAX) visits INT I can easily get the top 10 keyword hits with the following query: SELECT TOP 10 * FROM top_keywords WHERE ym BETWEEN '2010-05' AND '2010-05' ORDER BY visits DESC Now where it gets tricky is where I have to get the top 10 records for each report_id in the given date range (ym BETWEEN @start_date AND @end_date). How would I go about getting the top 10 for each report_id? I've stumbled across suggestions involving the use of ROW_NUMBER() and RANK(), but have been vastly unsuccessful in their implementation.

  • SQL 2008 table locked - can't work out why

    - by Mr. Flibble
    I have two databases on one SQL 2008 server. Database 1 seems to be causing a lock on a table on database 2. There no queries are running on database 1 that should affect database 2. Is this normal behaviour? When I view the running queries with this command SELECT sqltext.TEXT, req.session_id, req.status, req.command, req.cpu_time, req.total_elapsed_time/1000 [seconds] FROM sys.dm_exec_requests req CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS sqltext it tells me as much, and says that the command on database 2 is suspended. I'm at a bit of a loss. What sort of things should I look at to work out why the table in database 2 is locked?

  • How to find Junit tests that are using a given Java method directly or indirectly

    - by IT-Worx
    Assume there are Java project and Junit project in an Eclipse workspace. And All the unit tests are located in the Junit project and dependent on the application Java project. When making changes to a Java method, I need to find the unit tests that are using the method directly or indirectly, so that I can run the corresponding tests locally in my PC before checking into source control. I don't want to run the entire junit project since it takes time. I could use Eclipse call hierarchy to expand caller methods one by one until I find a test method. But for a project including more than 1 million lines of source code, digging down the call hierarchy takes time too. The search scope within call hierarchy view doesn't seem help much. Appreciate any help.

  • Character encoding problem in my website.

    - by vikyboss
    I own a website that was recently moved to a different server, now I can see some weird characters. Initially the website was coded with UTF-8 encoding. The weird characters disappears if I change the View Character encoding to Western(8859-1) in my browser. Therefore, I changed the source of the website to use this Western one, but still I can see the weird characters and they doesn't seem to disappear. Can anyone help me with this. Thanks in advance.

  • Is possible to set generic type by another class?

    - by Soul_Master
    I use ASP.NET MVC for serving web application and I want to create something like the following code. <% using(HTML.Form(Model)) { %> <% HTML.CreateTextBox('txt1', x => x.Property1); <% } From the above code, Form extension method will receive object that represent type of current Model object in current View page. Next, CreateTextBox method will receive type from Form method and I can bind textbox to some property of this model. Update 1 The following code is code of CreateTextBox method that will create instance of TextBox class. public static CreateTextBox(string value, Expression<Func<object>> bindedProperty) { // T should be receive from HTML.Form method or class return new TextBox<T>(value); } Is it possible to creating some code that doing something like the above code?

  • Orverride Problem for Custom Design on Product - Magneto

    - by Chris
    I am running several sites in several different languages off of single instance of magneto. There are two main styles Site 1 Site 2 Each site has some cusomtimizations based on language So each shop view has an some templates defined Site 2 - DE Site 2 - UK Now the problem is that when I apply a product level design, it forget's about the language level definition and skips back to the main definition. I want it to work like this Site 2 Site 2 DE Product Style But Instead it seems to work like this Site 2 Site 2 DE Product Style Where Site 2 DE is not ignored because a custom product style has been defined. How can I get the first hierarchy to work? So that my product styles do not override the language styles completely.

  • UIViewController: setToolbarItems vs navigationItem

    - by Paul Sanwald
    my application has a UIViewController subclass which is being managed by a UINavigationController. In the viewDidLoad of my UIViewController subclass, I was attempting to add a UIBarButtonItem to the toolbar like this: settingsButton = [[UIBarButtonItem alloc] initWithTitle:@"Settings" style:UIBarButtonItemStylePlain target:self action:@selector(viewSettings:)]; [self setToolbarItems:[NSArray arrayWithObject:settingsButton]]; this wasn't working out for me, so after some googling around, I tried this: [[self navigationItem] setRightBarButtonItem:settingsButton]; which worked out fine. from reading the UIViewController documentation, I'm still confused about why setToolbarItems wasn't working. I verified in the debugger that the button was in the toolbarItems array in the viewDidAppear method. the button itself just wasn't appearing on my toolbar. so, my question is, why didn't setToolbarItems work for me in the first code snippet? I don't have the toolbar configured in my xib for this view controller at all, if that makes a difference.

  • Conditional root_url (index)

    - by vise
    I'd like my application to display different data on the frontpage depending on whether the user has been logged in or not. def index if current_user # render another controllers action else # render another controllers action end end I can achieve this by using render_component. However it has been obsolete for some time. Although I can still use it as a plugin, I'm interested if anyone has a better approach. Just take in mind that rendering another controller's view directly is not an option. Thanks.

  • what is main focus for a developer when coding?

    - by ajsie
    i read a lot of books about how to code right and usually the are talking about all these techniques from a point of view i can't understand. eg. lets consider the singleton pattern. i'm restricting so the class can only be instantiated once. but since it's only me creating the application, if i know that the class only should be instantiated once, then why would i create it a second time? i feel like missing the big picture. what is my main goal when coding an application? how should i think? thanks

  • show activity indicator while loading ViewController

    - by Crystal
    I have a ViewController that takes time to load its views. When I run Instruments, I see from the home screen, if I tap on the icon that pushes that view controller onto the stack, it's half laying out the views, and half getting the data for the views. I tried adding an activity indicator to display on the home screen over the button when the button is pressed to push the LongRunningViewController onto the stack. So I basically do this: - (IBAction)puzzleView:(id)sender { dispatch_async(dispatch_get_main_queue(), ^{ [self.activityIndicator startAnimating]; }); PuzzleViewController *detailViewController = [[[PuzzleViewController alloc] init] autorelease]; [self.navigationController pushViewController:detailViewController animated:YES]; [self.activityIndicator stopAnimating]; }

  • multiple regionDidChangeAnimated calls - what gives?

    - by mvexel
    I have a MKMapView inside a UITableView as a custom cell (don't ask ;) - don't know if it matters really), for which I register a regionDidChangeAnimated delegate method. This method gets called three times when the UITableView is loaded - once with the actual region and then two more times with a region that is way off. In the simulator, I consistently get a region with center (+37.43997405, -97.03125000). On the device, it seems to depend on the location reported by the location manager, which initializes the map view. Why am I getting three regionDidChangeAnimated calls? And why are the center coordinates for the last two of them off? This is the code I use to get the center coordinates: - (void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated { CLLocation *l = [[CLLocation alloc] initWithLatitude:self.mapView.centerCoordinate.latitude longitude:self.mapView.centerCoordinate.longitude]; (....)

  • Document conversion and viewing, what are the cutting edge solutions?

    - by DigitalLawyer
    Goal: building a web application where a user can: Upload a document (doc, docx, pdf, additional office formats a +) View that document in a browser, preferably in html Download the document (in doc, pdf, additional open formats a +) Current solution: Ruby on Rails Application on Rackspace Users can upload doc and pdf files (AWS) Files can be downloaded in the format in which they were uploaded Thumbnail generation ([doc, pdf] - pdf - png) is done through AbiWord. Certain doc files do not convert well. Documents can be viewed in embedded Google docs viewer (https://docs.google.com/viewer). Certain doc files cannot be displayed. Little flexibility. Potential improvements: Document viewing in pdf through pdf.js Viewing in html (+ annotation) through Crocodoc I'd be glad to hear other users' experiences, and will add good recommendations to this list.
