  • How do I branch if message.properties-code exists

    - by skurt
    I want to branch if a message-property-code does exist or not. <g:if test="${message(code: 'default.code.foo')}"> true </g:if><g:else> false </g:else> should answer true if there a message property named default.code.foo and false if not. It fails because it answers the code if there is no property for it.

  • Simple servlet or filter to process form

    - by David
    Is there a simple framework for processing form submissions via a servlet? For my needs, a framework like STRUTS seems like over kill. My ideal processor would be a servlet that converts form elements into a bean object, possibly using typing information in the form to help with the conversion. Does something like this exist or is there another solution out there geared toward simpler needs? Thanks!

  • ASP.NET MVC model state as text

    - by David Moorhouse
    Is there an easy way to get a summary string of the errors that have been added to a controller's modelstate? I'm looking to return this in an Ajax method and want the validation errors etc to be returned to the client (i.e. the view does not exist for this method call). Or do I have to loop through the modelstate and look at each object and extract the error text manually?

  • Is there anyway to "probe" a method in common lisp

    - by Michael Minerva
    My application allows the user to create their own methods indirectly and I later need to refer to these methods. I am wondering if there is a way (for error checking purposes) to test if a method exists without trying to execute it. If I just try and call the method and it doesn't exist this will crash my application.

  • Making many network shares appear as one

    - by jimbojw
    Givens: disk is cheap, and there's plenty lying around on various computers around the corporate intranet redundant contiguous large storage volumes are expensive Problem: It would be fantastic to have a single entry point (drive letter, network path) that presents all this space as one contiguous filesystem, effectively abstracting the disk and network architecture from the paths presented to users. Does anyone know how to implement such a solution? I'm open to Windows and non-windows solutions, free and proprietary.

  • #region in XAML

    - by kenny
    I actually don't like #region in my code. BUT for some reason call me crazy, I would like to have them in my XAML. I would like whole sections to have a #region-like thing and collapse them (e.g. my <Window.CommandBindings, <Grid.*Definitions, <Menu, <Toolbar, etc.. Does this exist? If not, how about <RegionCollapse

  • Frequent Functions: How to Structure?

    - by cam
    How should one structure their frequently used non-important functions (conversions, etc) in C# since everything must be contained in an object? Usually I take all these functions and put them in a static Utility class. Is this a good practice? How do most developers do it?

  • Canvas total width (visible width + hidden scrollable part)

    - by Leeron
    It's probably a no brainer, but I've spent the last 40 minutes or so looking for it to no avial. I have a Canvas control with a fixed width and a horizontal scrollbar. I'm trying to find the actual width of the control. The .width (fixed width) + the part being reviled by the scrollbar. I tried explicitWidth, width + maxHorizontalScrollPosition, and some other combos but non of them hit the spot.

  • How does SO's form remember previous input values?

    - by user198729
    I've noticed that the Title or Body part is remembered if I come back to the Ask Question page by pressing Back button of my browser. This feature is available in all browsers I tested, but doesn't exist for the forms in my own projects. How can I approach that effect? UPDATE I still don't have any clue yet,but guess it that some kind of client cache enabled by http headers or javascript?

    - by John Leidegren
    I get an "The remote name could not be resolved: 'mine.com'" When using this open ID identifier: https://www.google.com/accounts/o8/site-xrds?hd=mine.com And it's true, that the mine.com DNS record doesn't exist. But I'm wondering why it goes to look there in the first place. All I want to be doing is to check if the user can login to our hosted domain. Is that really so hard?

  • Is it standard behavior for this code to throw a NullPointerException?

    - by Eric
    I've had a big problem in some library code, which I've pinned down to a single statement: System.out.println((String) null); Ok, the code doesn't actually look like that, but it certainly calls println with a null argument. Doing this causes my whole applicaio to throw an unexpected NullPointerException. In general, should println throw this exception under that circumstance, or is this non-standard behavior due to a poor implementation of the out instance?

  • .NET Compact Framework app that will run on both Professional and Standard

    - by CJCraft.com
    Is there any guidance on creating apps that will run on both professional (touch-screen) and standard (non-touch-screen) devices. I have a simple application that is mostly text and buttons that in theory should be able to run on both professional and standard devices with little if any modification. It seems the IDE wants to make this hard to impossible, but I expect it to be possible. Any advice?

  • Python 3: list atributes within a class object

    - by MadSc13ntist
    is there a way that if the following class is created; I can grab a list of attributes that exist. (this class is just an bland example, it is not my task at hand) class new_class(): def __init__(self, number): self.multi = int(number) * 2 self.str = str(number) a = new_class(2) print(', '.join(a.SOMETHING)) * the attempt is that "multi, str" will print. the point here is that if a class object has attributes added at different parts of a script that I can grab a quick listing of the attributes which are defined.
