  • php gdlib angle problem

    - by creativz
    I'm using php gd lib 5.2.13 and tried to make a picture with imagettftext ($image, $color and $font are defined of course). imagettftext($image, 12, 90, 10, 20, $black, $font, "This.is_a test 123"); //image, font size, angle, x value, y value, color, font, text As you can see I want the angle to be 90°. The problem is that the text is not beeing rotated properly, e.g. the dots are at the top (and not at the bottom) of the text. I read that this is a common issue and has been fixed in php gdlib 5.3, But since I have 5.2.13 running on a webhost (...) is there a solution to rotate it properly with using gdlib 5.2.13? Thanks!

  • Aligning all panel components java

    - by destructo_gold
    I am using the BoxLayout layout manager in java, and have aligned a bunch of components: myLabel.setAlignmentX(Component.LEFT_ALIGNMENT); myTextBox.setAlignmentX(Component.LEFT_ALIGNMENT); myButton.setAlignmentX(Component.LEFT_ALIGNMENT); ... I have a lot of components, and this seems over the top. Is there a shorthand way? I tried the following, but setAlignmentX isn't a method inside Component? for (Component c : personPanel.getComponents()) { c.setAlignmentX(Component.LEFT_ALIGNMENT); }

  • Why does concatenating strings in the argument of EXEC sometimes cause a syntax error in T-SQL?

    - by Tim Goodman
    In MS SQL Server Management Studio 2005, running this code EXEC('SELECT * FROM employees WHERE employeeID = ' + CAST(3 AS VARCHAR)) gives this error: Incorrect syntax near 'CAST' However, if I do this, it works: DECLARE @temp VARCHAR(4000) SET @temp = 'SELECT * FROM employees WHERE employeeID = ' + CAST(3 AS VARCHAR) EXEC(@temp) I found an explanation here: http://stackoverflow.com/questions/1044831/t-sql-cannot-pass-concatenated-string-as-argument-to-stored-procedure According to the accepted answer, EXEC can take a local variable or a value as its argument, but not an expression. However, if that's the case, why does this work: DECLARE @temp VARCHAR(4000) SET @temp = CAST(3 AS VARCHAR) EXEC('SELECT * FROM employees WHERE employeeID = ' + @temp) 'SELECT * FROM employees WHERE employeeID = ' + @temp sure looks like an expression to me, but the code executes with no errors.

  • T-SQL: Build Nested Set From Parent-Child Relationship

    - by Peder Rice
    I have a table that stores my Customer hierarchy with a nested set (due to the specific design of the application, I wasn't able to leverage just a Customer/Parent Customer mapping table). To simplify maintenance of this table, I've built a couple of stored procedures to handle moving nodes around and creating new nodes, but it's significantly more work than maintaining a Customer/Parent Customer table. Further, these structures are very fragile. So I'm looking for a way to have a Customer/Parent Customer table and then convert that table to a nested set on demand. Does anyone have a link to such an implementation?

  • Visual Studio stops debugging with no errors unexpectedly

    - by HeavyWave
    I am debugging a project and Visual Studio stops debugging and closes the program on the following line with no exceptions or error messages (I have enabled notifications for any thrown exceptions in options): var query = Session.Linq<RSS>() .Where(x => x.LastRetrieved <= date || x.LastRetrieved == null) .Where(x => x.Moderated); Where Session.Linq refers to LINQ2NHibernate. Anyway, the question is: what are the possible reasons for such behavior? Tested both on VS 2010 and 2008 - they behave identically just falling out of debugging.

  • In django, how can I include some default records in my models.py?

    - by kdt
    If I have a models.py like class WidgetType(models.Model): name = models.CharField(max_length=200) class Widget(models.Model): typeid = models.ForeignKey(WidgetType) data = models.CharField(max_length=200) How can I build in a set of built in constant values for WidgetType when I know I'm only going to have a certain few types of widget? Clearly I could fire up my admin interface and add them by hand, but I'd like to simplify configuration by having it built into the python.

  • Microsoft JScript runtime error: Sys.InvalidOperationException: Two components with the same id.

    - by Irwin
    I'm working in ASP .NET dynamic data. In one of my edit controls I wanted to allow the user to add records from a related table to the current page. (Literally, if you are on the orders page, you would be allowed to add a new customer to the system on this page as well, and then associate it with that order). So, I have a DetailsView set to InsertMode, nested inside of an UpdatePanel, which is shown by a ModalPopupExtender which is invoked when 'add new' is clicked. This doohickey works the first time i execute this process, that is, a customer is added (and i update the dropdown list as well). However, I realized it didn't work (properly) again until I refreshed the entire page. When I attached my debugger, my worst fears were realized (ok, not really). But an exception was being thrown: "Microsoft JScript runtime error: Sys.InvalidOperationException: Two components with the same id." Which seemed to be complaining about a Calendar Extender Control that is part of the details view. Any guidance on what's going on here would be great. Thanks.

  • localhost/live - detect by HTTP_HOST

    - by Adam Kiss
    Hello, let's say I develop locally and debug small things on live server. Is it good idea to have something like this in my code? : $is_local = (strpos($_SERVER['http_host'], 'localhost') !== false); define ('DEBUG',$is_local); And then use it through my code, when setting stuff? $mysql_settings = (DEBUG) ? array(/*localhost settings*/) : array(/*live settings*/); This way, I can use the same files live and on localhost, so I can sync without any fear of having wrong e.g. connection settings on live server. Is it good or wrong idea?

  • How does Task Parallel Library scale on a terminal server or in a web application?

    - by Lasse V. Karlsen
    I understand that the TPL uses work-stealing queues for its tasks when I execute things like Parallel.For and similar constructs. If I understand this correctly, the construct will spin up a number of tasks, where each will start processing items. If one of the tasks complete their allotted items, it will start stealing items from the other tasks which hasn't yet completed theirs. This solves the problem where items 1-100 are cheap to process and items 101-200 are costly, and one of the two tasks would just sit idle until the other completed. (I know this is a simplified exaplanation.) However, how will this scale on a terminal server or in a web application (assuming we use TPL in code that would run in the web app)? Can we risk saturating the CPUs with tasks just because there are N instances of our application running side by side? Is there any information on this topic that I should read? I've yet to find anything in particular, but that doesn't mean there is none.

  • Tool to highlight and annotate text on websites?

    - by doug
    When I read something I need to underscore what I like, or what I think is important, and to take notices about that read, near on that current paragraph. So, does anyone know a Firefox add-on or something else (another browser, any other application) which can provide me such a functionality? ps: I've tried some research tools as Zotero, but it is not what I'm looking for.

  • Load/Store Objects in file in Java

    I want to store an object from my class in file, and after that to be able to load the object from this file. But somewhere I am making a mistake(s) and cannot figure out where. May I receive some help? public class GameManagerSystem implements GameManager, Serializable { private static final long serialVersionUID = -5966618586666474164L; HashMap<Game, GameStatus> games; HashMap<Ticket, ArrayList<Object>> baggage; HashSet<Ticket> bookedTickets; Place place; public GameManagerSystem(Place place) { super(); this.games = new HashMap<Game, GameStatus>(); this.baggage = new HashMap<Ticket, ArrayList<Object>>(); this.bookedTickets = new HashSet<Ticket>(); this.place = place; } public static GameManager createManagerSystem(Game at) { return new GameManagerSystem(at); } public boolean store(File f) { try { FileOutputStream fos = new FileOutputStream(f); ObjectOutputStream oos = new ObjectOutputStream(fos); oos.writeObject(games); oos.writeObject(bookedTickets); oos.writeObject(baggage); oos.close(); fos.close(); } catch (IOException ex) { return false; } return true; } public boolean load(File f) { try { FileInputStream fis = new FileInputStream(f); ObjectInputStream ois = new ObjectInputStream(fis); this.games = (HashMap<Game,GameStatus>)ois.readObject(); this.bookedTickets = (HashSet<Ticket>)ois.readObject(); this.baggage = (HashMap<Ticket,ArrayList<Object>>)ois.readObject(); ois.close(); fis.close(); } catch (IOException e) { return false; } catch (ClassNotFoundException e) { return false; } return true; } . . . } public class JUnitDemo { GameManager manager; @Before public void setUp() { manager = GameManagerSystem.createManagerSystem(Place.ENG); } @Test public void testStore() { Game g = new Game(new Date(), Teams.LIONS, Teams.SHARKS); manager.registerGame(g); File file = new File("file.ser"); assertTrue(airport.store(file)); } }

  • Suggestions on how to implement a UI Element to display a long image in iPhone.

    - by Tattat
    I want to display a long image on iPhone. The user can swipe left or right to see difficult parts of the image. I want to spite the long image into different parts... for example, a long long image is 1000* 100; I want to display 100*100 for each time. When the image is loaded, it shows from x:0 to x:100. When user swipe right, it becomes x:101, x:200. When the user swipe left, it back to x:0, x:100, when the user continue to swipe right, it show x:201, x:300. I am thinking how to implement this specified imageView. I have two ideas now. First, make my own imageView, which super class is UIImageView, and overriding the swipe left, swipe right method. Second, make my own UIView. just implement the user swipe left/right action. Which way you think is better, or any better ideas on implement this? thz u.
