  • Is it possible to publish component revisions within workflow?

    - by Ianthe
    Our current setup is that we have two targets, Staging and Live. Collaborators may update the affected component while it is still within the workflow. A final activity is set to publish the related pages to Live. Is it possible to publish component updates (revisions e.g. 2.2, 2.5) to Staging from within the workflow? The TOM API documentation for Page.Publish() method does not seem to have an input parameter to fullfil such purpose.

  • JS Display Content based on Dropdown User input

    - by Thomas
    I am working on a search box that displays different options based on a users selection via dropdown box. Basically I need a really clean, light-weight method for switching out different divs without reloading the page. Im new to JS, but I know enough that there should be some really simple way of setting the display property using JS - Im just not totally sure how to go about it. Any help would be really appreciated, thanks.

  • Should Python import statements always be at the top of a module?

    - by Adam J. Forster
    PEP 08 states: Imports are always put at the top of the file, just after any module comments and docstrings, and before module globals and constants. However if the class/method/function that I am importing is only used in rare cases, surely it is more efficient to do the import when it is needed? Isn't this: class SomeClass(object): def not_often_called(self) from datetime import datetime self.datetime = datetime.now() more efficient than this? from datetime import datetime class SomeClass(object): def not_often_called(self) self.datetime = datetime.now()

  • Making a Game Without Graphics?

    - by cam
    Is it possible or even constructive to make a game without any graphics (but is intended to become graphical) I'm not good with graphics at all, so I'd like to write the skeleton for the game then have a graphics programmer/artist fill in the rest. I could write up all the major classes, and their interactions, and all the major functions/parts of the game. If so, what should I do to make it easier to integrate graphics into the game later on (every drawn object should have a Draw, Rotate, Collide, etc method) ?

  • opengl es render but dont show on display

    - by Sponge
    i have written a object selection algorithm which picks the objects by there color. i give every object an unique color and then i just have to use the glReadPixels method to check which object was selected this works fine and is really fast but the problem is that the frame is displayed on the screen with all the picking-colors so the screen flashes every time you select something. so my question is: how do i write everything in the correct display buffer but dont display it on the screen to avoid these flashes?

  • What does the C# operator => mean?

    - by Mr. Mark
    Answers to a recent post (Any chances to imitate times() Ruby method in C#?) use the = operator in the usage examples. What does this operator do? I can't locate it in my C# book, and it is hard to search for symbols like this online. (I couldn't find it.)

  • Spring security @notation for IS_AUTHENTICATED_FULLY?

    - by wuntee
    I am simply trying to allow a user access to a method if they are authenticated, but nothing I am doing seems to work. Is there a way to just check if the user has been authenticated? The following still denies the user even when authenticated... Is there a built in role for an authenticated user? @RequestMapping("/secure") @PreAuthorize("hasRole('IS_AUTHENTICATED_FULLY')") public String secure(ModelMap map){ return("secure"); }

  • How to lock files in a tomcat web application?

    - by yankee
    The Java manual says: The locks held on a particular file by a single Java virtual machine do not overlap. The overlaps method may be used to test whether a candidate lock range overlaps an existing lock. I guess that if I lock a file in a tomcat web application I can't be sure that every call to this application is done by a different JVM, can I? So how can I lock files within my tomcat application in a reliable way?

  • How to generate real UTF-8 XML with grails without the escape characters?

    - by AngeDeLaMort
    I have been wondering why when I set the encoding to UTF-8 and rendering the XML it replace the extended characters by escape characters (or character reference) like &#x2019; instead of '? I'm using the Render method render(contentType:"text/xml", encoding:"UTF-8") {...} with a proper header render(contentType:"text/xml", encoding:"UTF-8", text:"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n") Any idea if there is a way to write it properly? Thanks.

  • Labeling a chart in VB.NET (VS 2008)

    - by typoknig
    Hi all, I have created a basic chart in VB.NET (VS 2008) and it is working good, but I would like to label the axies of the chart. The method "AxisLabel" is not what I am looking for. I want to put the word "Dollars" vertically on the far left hand side of my chart (just left of the numbers labeling the "y" axis) and the word "Months" horizontally at the bottom of the chart but above the legend (just below the numbers labeling the "x" axis). Check the picture out...

  • NHibernate requires events to be virtual?

    - by Jimit
    I'm attempting to map an entity hierarchy using NHibernate almost all of which have events. When attempting to build a session factory however, I get error messages similar to the following: Core.Domain.Entities.Delivery: method remove_Scheduled should be virtual Delivery is an entity in my domain model with an event called Scheduled. Since events cannot be declared virtual I'm at a loss as to how to proceed here. Why would NHibernate need events to be virtual?

  • OpenMP implementations in VC++ 2008, 2010

    - by John
    Depending on implementation, OMP can be quite useful to parallelize fairly arbitrary bits of code - e.g a parallel section inside a method that calls two independent methods - or it can be bad. It depends on how threads are created/cached, I think. How does the VC++ 2008 implementation work? And is the 2010 implementation significantly different in terms of features and performance/flexibility?
