  • automatic xml conversion in scala

    - by Jeff Bowman
    Let's say I have the following class: class Person(val firstName:String, val lastName:String) Is there an automatic way to generate xml from this class without having to hand create a toXml() method? Ideally the output would be something like: <Person <firstNameJohn</firstName <lastNameSmith</lastName </Person It seems like there should be a way to do this without having to write all that out manually. Perhaps there is a trait I haven't found yet?

  • Using Python to add/remove Ubuntu login script items

    - by codebox_rob
    I have written a Python application and would like to give my users the option of having the app automatically launch itself when the user logs in. It is important that the user is able to toggle this option on/off from within the app itself, rather than having to manually edit login scripts, so this needs to be done from within the Python code rather than from a shell script. The app is deployed on Ubuntu Linux, any suggestions for the best way of doing this?

  • How can I center something if I don't know ahead of time what the width is?

    - by zeckdude
    I am trying to center a paragraph tag with some text in it within a div, but I can't seem to center it using margin: 0 auto without having to specify a fixed width for the paragraph. I don't want to specify a fixed width, because I will have dynamic text coming into the paragraph tag and it will always be a different width based on how much text it is. Does anyone know how I can center the paragraph tag within the div without having to specify a fixed width for the paragraph or without using tables?

  • Why is overloading operator&() prohibited for classes stored in STL containers?

    - by sharptooth
    Suddenly in this article ("problem 2") I see a statement that C++ Standard prohibits using STL containers for storing elemants of class if that class has an overloaded operator&(). Having overloaded operator&() can indeed be problematic, but looks like a default "address-of" operator can be used easily through a set of dirty-looking casts that are used in boost::addressof() and are believed to be portable and standard-compilant. Why is having an overloaded operator&() prohibited for classes stored in STL containers while the boost::addressof() workaround exists?

  • How do I embed a binary within a Delphi executable and extract at runtime?

    - by Mick
    I'd like to embed an executable inside of my Delphi binary and extract it at runtime. The purpose of this is to ensure that a helper utility is always available on the system, without having to distribute multiple files. With Delphi 2007 I have used JvDataEmbedded, but I am building a console application and I want to know if anyone knows of another way to do it without having to add a hidden form for JvDataEmbedded. I am using Delphi 2010.

  • JPA CascadeType.ALL does not delete orphans.

    - by Paul Whelan
    I am having trouble deleting orphan nodes using JPA with the following mapping @OneToMany (cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy = "owner") private List<Bikes> bikes; I am having the issue of the orphaned roles hanging around the database. I can use the @org.hibernate.annotations.Cascade Hibernate specific tag but obviously I don't want to tie my solution into a hibernate implementation. Any pointers greatly appreciated.

  • Prefix and Postfix operator's necessity

    - by Karthi prime
    What is the necessity of both prefix and postfix increment operators? Is not one enough? To the point, there exists like a similar while/do-while necessity problem, yet, there in no so much confusion (in understanding and usage) in having them, but with having both prefix and postfix (like priority of these operators, their association, usage, working). And do anyone been through a situation where you saidd "Hey, I am going to use postfix increment. Its useful here"

  • Best Practices for Working with Multiple Monitors in Visual Studio 2010

    - by Clever Human
    Now that Visual Studio 2010 has support for multiple monitors, I am curious how other people have their environments arranged. I have yet to come up with an arrangement that I am really satisfied with. The current best I have come up with for my 2 monitor system is to have all code windows detached. Then, on my primary monitor, I am able to have two code windows side by side (using the Windows 7 keyboard shortcuts WinKey+LeftArrow and WinKey+RightArrow.) On my secondary monitor I put the rest of the IDE with all of the tool windows that are normally on the bottom (errors list, find window, call stack, etc...) docked where the code windows normally go. I've also tried having all those things detached and having almost nothing in the IDE proper. The problems with this layout are: Newly opened code windows always open in the IDE, not on top of one of the detached windows. Detached code windows do not remember their exact placement from session to session (they are slightly off, having me to use the winkey + arrow key shortcut again and again for each window. There seems to be no way to have the code panes aware that they are on top of one another (IE -- multiple tabs.) The CTRL+TAB shortcut always displays on top of the IDE proper. The Code Panes are always "on top" of (children of) the IDE. So clicking on any code pane brings the IDE to the foreground, even when I care only about that code pane, and not the IDE. Other more minor issues... What would go a long way to making this better is having the code panes detach such that they are tab strips that can have other code panes docked within them. The new multi-monitor support in VS2010 is good, but it still seems really lacking. Can these issues be solved with an add-in? If so, is anyone aware of one? Is there a better way to work with the IDE on multiple monitors than what I am doing? NOTE: While this question is subjective (there is certainly no "this is the best way and that's final" answer) I'd really like to know possibly better methods of working with the IDE than what I have come up with. The intent is not to start a "mine's best" flame war.

  • Microsoft Surface: "Read" the tag value of an IdentityTag

    - by sofri
    Hi, is it possible to read the value of an IdentityTag if you place it on the TagVisualizer, without having initalized it before? I would like to use the tags for registering a new object on the Surface but having all the "free" IdentityTags in a Collection for initalizing them all... There must be a better way to do in I think. But the TagVisualizer doesn't seem to do anything when you put a tag on it that it doesn't know.

  • Prevent drop down list options scrolling on Windows in SWT

    - by parxier
    One of the drop down lists in my Java SWT application has 8 fixed options. When I click on it only 5 first options are visible and I have to scroll the list down to view the rest. Is there any way to force it to make all options visible without having to scroll down? There is another similar .NET application that has same drop down list with the same options and they all are visible without having to scroll down!
