• How to find the exact name of the view in asp.net mvc (including the case)

  - by Charles Prakash Dasari

  I have a control in ASP.NET MVC that spits out JavaScript in the page header (in the view page). I derive some values from the current view name (including its case). Let's say we are talking about the path: /Home/Index - my control spits out JavaScript to call a function with the view name - in its exact case - e.g. someFunction('Index'). Now when I try to navigate to my view using '/home/index', the view name is returned as 'index' which is causing issues in my JavaScript as I rely on the casing for it on the JS side. Is there any way to know the exact view name (as it was defined) from the path that got mapped into this view.

• SQL Server 2008 - Get Latest Record from Joined Table

  - by user336786

  Hello, I have a SQL Server 2008 database. This database has two tables called Customer and Order. These tables are defined as follows: Customer -------- ID, First Name, Last Name Order ----- ID, CustomerID, Date, Description I am trying to write a query that returns all of the customers in my database. If the user has placed at least one order, I want to return the information associated with the most recent order placed. Currently, I have the following: SELECT * FROM Customer c LEFT OUTER JOIN Order o ON c.[ID]=o.[CustomerID] As you can imagine, this will return all of the orders associated with a customer. In reality though, I only want the most recent one. How do I do this in SQL? Thank you!

• How should I use try...except while defining a function?

  - by SpawnCxy

  Hi all, I find I've been confused by the problem that when I needn't to use try..except.For last few days it was used in almost every function I defined which I think maybe a bad practice.For example: class mongodb(object): def getRecords(self,tname,conditions=''): try: col = eval("self.db.%s" %tname) recs = col.find(condition) return recs except Exception,e: #here make some error log with e.message What I thought is ,exceptions may be raised everywhere and I have to use try to get them. And my question is,is it a good practice to use it everywhere when defining functions?If not are there any principles for it?Help would be appreciated! Regards

• How to design a database schema for storing text in multiple languages?

  - by stach

  We have a PostgreSQL database. And we have several tables which need to keep certain data in several languages (the list of possible languages is thankfully system-wide defined). For example lets start with: create table blah (id serial, foo text, bar text); Now, let's make it multilingual. How about: create table blah (id serial, foo_en text, foo_de text, foo_jp text, bar_en text, bar_de text, bar_jp text); That would be good for full-text search in Postgres. Just add a tsvector column for each language. But is it optimal? Maybe we should use another table to keep the translations? Like: create table texts (id serial, colspec text, obj_id int, language text, data text); Maybe, just maybe, we should use something else - something out of the SQL world? Any help is appreciated.

• How to get an array of all controllers in a Codeigniter project ?

  - by ashmckenzie

  I'd like to obtain a list of all controllers in a Codeiginiter project so I can easily loop through each of them and add defined routes. I can't seem to find a method that will give me what I'm after ? Here is the code snippet from the routes.php file where I would like to access the array: - // I'd like $controllers to be dynamically populated by a method // $controllers = array('pages', 'users'); // Loop through each controller and add controller/action routes // foreach ($controllers as $controller) { $route[$controller] = $controller . '/index'; $route[$controller . '/(.+)'] = $controller . '/$1'; } // Any URL that doesn't have a / in it should be tried as an action against // the pages controller // $route['([^\/]+)$'] = 'pages/$1';

• Hibernate entities: columns without entity properties

  - by lewap

  Is there a way to "magically" persist a column which is not represented as a property in an entity? Concretely I want to add audit info to an entity without having the audit info on the entity. The audit values are not stored in the entity, but are retrieved from the environment at the time of persisting the entity. This happens in a AuditInfoUserType. The nullSafeSet gets the info from the SecurityContext, instead of reading from the entity. In the hibernate mapping, however, the audit info properties have to be defined. Is there a way in hibernate to define columns without properties?

• Placing text on UIView in custom location

  - by JAM

  I am trying to calculate a position to place label on the screen. The goal is to place "word" label in lower right corner of the first square block If yellowish square is defined as myView = [[UIView alloc] initWithFrame:CGRectMake(100, 100, 70, 70)]; [self.view addSubview:myView]; [myView setBackgroundColor:[UIColor colorWithHexString:@"FFFFEC"]]; Using it, i'd like to place a label in it's lower right corner l1 = [[UILabel alloc] init]; [l1 setText:@"word"]; [l1 setFrame:CGRectMake(myView.frame.origin.x + myView.frame.size.width, myView.frame.origin.y + myView.frame.size.height, 700, 700)]; [l1 setFont:[UIFont fontWithName:@"Arial" size:10.0]]; [l1 setBackgroundColor:[UIColor colorWithHexString:@"CCFFFEC"]]; [l1 setTextAlignment:UITextAlignmentRight]; [l1 sizeToFit]; This is what happens: The matter here obviously, is in a correct offset. Knowing the font and size of text, how can one correctly calculate it?

• Issues with start activity for result

  - by rodkarom

  I have written an Activity using Theme.Holo.Dialog so that it works as an AlertDialog as a login/password notice. I've started this activity with startActivityForResult(...) using a request code I defined. The thing is, whenever I start the activity ´onActivityResult(...)´ is triggered immediately, the buttons get loaded and everything, but once I press them, even though I know the Activity is working because login does happen, there is no result sent back to the first Activity and I am calling setResult(...) and finish() after the buttons are pressed. Thanks in advance, first time using startActivityForResult so I'm sure I must be missing something.

• c# class design - what can I use instead of "static abstract"?

  - by Ryan

  I want to do the following public abstract class MyAbstractClass { public static abstract int MagicId { get; } public static void DoSomeMagic() { // Need to get the MagicId value defined in the concrete implementation } } public class MyConcreteClass : MyAbstractClass { public static override int MagicId { get { return 123; } } } However I can't because you can't have static abstract members. I understand why I can't do this - any recommendations for a design that will achieve much the same result? (For clarity - what I am trying to do is provide a library with an abstract base class but the concrete versions MUST implement a few properties/methods themselves and yes, there are good reasons for keeping it static.)

• closing sockets on linux and windows

  - by robUK

  Hello, gcc 4.4.4 c89 Visual Studio VC++ 2008 I am writing a cross platform client server application. It will run on both linux and windows. However, I am just wondering what I have done for closing the sockets is correct. I close the file descriptor. However, if there is a problem with closing it. What is the best way to handle this. Maybe some data is still being sent or received? Many thanks for any advice, if(close(sockfd) == -1) { #if defined ( _WIN32 ) fprintf(stderr, "[ %d ] [ %s ] [ %s ] [ %d ]\n", WSAGetLastError(), strerror(errno), __func__, __LINE__); #elif( __linux__ ) fprintf(stderr, "[ %s ] [ %s ] [ %d ]\n", strerror(errno), __func__, __LINE__); #endif return CS_FAILURE; }

• WCF Client - Best Practise

  - by user1663907

  I just wanted to hear your Opinion about a WCF Client implementation. I have an Server that provides several services like SecurityManager. This service is defined in the Interface ISecurityManager and implemented in the Class SecurityManager. So far everything is fine. On the Client side I want to implement the services calls via a seperated Class. My question is whether I do this also in an SecurityManager Class which implements the same ISecurityManager Interface? What is here the best practise? Thanks.

• SQL Server 2003: how can I assign a name to the SUM column ?

  - by Patrick

  hi, how can I assign a column name to the SUM column ? i.e. select OwnerUserId, SUM(PostScore) INTO Experts from ... I get this error: An object or column name is missing or empty. For SELECT INTO statements, verify each column has a name. For other statements, look for empty alias names. Aliases defined as "" or [] are not allowed. Change the alias to a valid name. I guess because the column containing the results of SUM has not name. thanks

• Accessing Controls Values Before Finishing Page_Load

  - by userk

  Hi. I'm with a problem and want to know if someone can help me. I'm creating a table with some controls and I want to save all control values in every postback. As the controls are just defined after the page_load, I can't solve my problem this way: object o; protected void Page_Load(object sender, EventArgs e) { o = createObject(); Create_Table(); if (Page.IsPostBack) Save_Data(); } I thought I could execute Save_Data() at the begining of every postback event, but I think that should exist a better way to solve my problem. Thanks.

• Accessing object's method within string

  - by Wild One

  Recently I was reading php documentation and found interesting note in string section: Functions, method calls, static class variables, and class constants inside {$} work since PHP 5. However, the value accessed will be interpreted as the name of a variable in the scope in which the string is defined. Using single curly braces ({}) will not work for accessing the return values of functions or methods or the values of class constants or static class variables. See www.php.net/manual/en/language.types.string.php It says, that I can't use curly syntax to get value returned by object's method call. Is it a mistake in manual or I misunderstood it, because I tried the following code and it works just fine: <?php class HelloWorld { public static function hello() { echo 'hello'; } } $a = new HelloWorld(); echo "{$a->hello()} world";

• Data manipulation without server side

  - by monczek

  Hi, I have to create a very simple webpage to show, filter and add data from not-yet-defined source (probably txt/xml/cvs). Records should be visible as a table, filtered using 3 criteria fields. There should be also possibility to add new records. My first thought was: XHTML + jQuery + csv2table + PicNet Table Filter. It does exactly what I want except adding rows - that is saving changes in source file (probably due to security risk). My question is - is there any possibility to do it without involving server side like asp.net, jee, php, sql? Source file is located on the server. Thanks for your ideas :-)

• Replace the callback for a GtkItem created from a GtkItemFactoryEntry

  - by rampion

  I'm writing a plugin that's modifying an existing UI. One thing I want to do is change what an existing menu item does. This is all using the Gtk library. The menu item (a GtkItem) is created from a GtkItemFactoryEntry (which is out of my control), and has its current behaviour defined by the callback in the GtkItemFactoryEntry. I can get handle on the menu item using gtk_item_factory_get_widget() and attach further actions to the menu item using gtk_signal_connect(), but I can't seem to disconnect the original callback using gtk_signal_disconnect() or gtk_signal_disconnect_by_func(). Is there any way I can remove or replace the original callback?

• How to get the Primary/Secondary color in jQuery UI Theme

  - by simonsanderson

  Is there a way to reference the colours used in the jQuery themes without creating a simple style for each theme that I may choose to use? Example: I have some text as follows <div>Hello</div> which I'd like to be change colour in line with my theme of the day. I wish to use the primary colour from a theme (say ui-lightness) which is "#1c94c4" as defined in several of the styles such as ui-state-default in ui-lightness.css The problem is that if I do the following <div class='ui-state-default'>Hello</div> I get all the other style effects, like borders and background colour, which are not right for my application What I'd like to do is something like <div class='ui-primary-color'>Hello</div> which would automatically change only the colour dependent on the theme. PS. Doing a pre-build pre-processing step to parse the themes and generate a customised css style would be my least favourable option here!

• iPhone: increasing size of view frame in a UItabbarcontroller?

  - by dpigera

  I currently have a UITabBarController defined, with the tab bar moved a few pixels down to make it thinner: self.tabBarController = [[UITabBarController alloc] init]; self.tabBarController.tabBar.frame=CGRectMake(0,self.window.bounds.size.height-38.5,self.window.bounds.size.width,50); [self.window addSubview:self.tabBarController.view]; I then have a UIViewController object assigned to the first tab using: Home *home = [[Home alloc] initWithNibName:@"Home" bundle:nil]; UINavigationController *nHome = [[UINavigationController alloc] initWithRootViewController:home]; nHome.tabBarItem.image=[UIImage imageNamed:@"home.png"]; [tabBarController setViewControllers:[NSArray arrayWithObjects:nHome,nil]]; As a result, there is a thin sliver of space between the tabbarcontroller and the view. Can someone please tell me how I can get rid of this space?

• What is the difference between these two ways of creating NSStrings?

  - by adame

  NSString *myString = @"Hello"; NSString *myString = [NSString stringWithString:@"Hello"]; I understand that using method (1) creates a pointer to a string literal that is defined as static memory (and cannot be deallocated) and that using (2) creates an NSString object that will be autoreleased. Is using method (1) bad? What are the major differences? Is there any instances where you would want to use (1)? Is there a performance difference? P.S. I have searched extensively on Stack Overflow and while there are questions on the same topic, none of them have answers to the questions I have posted above.

• PDOException “could not find driver”

  - by Mike

  I have just installed Debian Lenny with Apache, MySQL, and PHP and I am receiving a PDOException could not find driver. This is the specific line of code it is referring to: $dbh = new PDO('mysql:host=' . DB_HOST . ';dbname=' . DB_NAME, DB_USER, DB_PASS) DB_HOST, DB_NAME, DB_USER, and DB_PASS are constants that I have defined. It works fine on the production server (and on my previous Ubuntu Server setup). Is this something to do with my PHP installation? Searching the internet has not helped, all I get is experts-exchange and examples, but no solutions.

• Is there a "concise" way to do namespacing in JavaScript?

  - by olliej

  I've frequently encountered sites that put all of their javascript inside a "namespace" structure along the lines of namespaces = { com : { example: { example.com's data} } But setting this up safely with respect to other namespaced frameworks seems to require a relatively hefty amount of code (defined as 2 lines). I was wondering whether anyone knows of a concise way to do this? and whether there's a relatively standard/consistent way to structure it? eg. is the "com" namespace directly attached to the global object, or is it attached through a namespace object? [Edit: whoops, obviously {com = { ... } } wouldn't accomplish anything close to what i intended, thanks to Shog9 for pointing that out. :D]

• NameError on accessing ancestor constants when using Class.new?

  - by PDG

  To my current knowledge Ruby classes defined with Class.new should not differ from classes created with the class keyword. Then why do following classes B and C behave differently? class A TEST = 'A' def test TEST end end class B < A def test TEST end end C = Class.new(A) { def test TEST end } puts 'A: ' + A.new.test # => "A: A" puts 'B: ' + B.new.test # => "B: A" puts 'C: ' + C.new.test # => uninitialized constant TEST (NameError) Tested with ruby 1.9.3p327 and ruby 1.8.7p358.
