  • What are the 'best' XNA developed games for PC?

    - by RichK
    I've had a quick google, but can't find anything obvious that answers the question. What are the best games developed using XNA for PC? Any flagship games, original games.. etc? Obviously 'best' is pretty subjective, but I'm sure they'll be a common consensus on some of the good ones. (I don't own an XBox (if that matters...))

  • Should I use office open xml or rdlc reports?

    - by Si Keep
    I need to provide the facility for a user to download Word and Excel reports from my web site. I was intending to use the Office Open Xml SDK but have just stumbled across RDLC. My question is should I consider RDLC? Does it give me the same flexability that the Office Open Xml SDK does? What are the pro's and cons?

  • Sharepoint page level security

    - by ifunky
    Hi, Another SharePoint question from myself! I've created a subsite and from within Sharepoint designer I've created a new aspx page, all nice and simple so far. I can't seem to find where I can change the security on this new page, only site admins can view the page and everyone else gets access denied. It doesn't seem to inherit the permissions from the parent and I can't see where to change the security settings! Please help, I'm sure it's something simple! Thanks Dan

  • Good design of mapping Java Domain objects to Tables (using Hibernate)

    - by M. McKenzie
    Hey guys, I have a question that is more in the realm of design, than implementation. I'm also happy for anyone to point out resources for the answer and I'll gladly, research for myself. Highly simplified Java and SQL: Say I have a business domain POJO called 'Picture' with three attributes. class Picture int idPicture String fileName long size Say I have another business domain POJO called "Item" with 3 attributes Class Item int idItem String itemName ArrayList itemPictures These would be a normal simple relationship. You could say that 'Picture' object, will never exist outside an 'Item' object. Assume a picture belongs only to a specific item, but that an item can have multiple pictures Now - using good database design (3rd Normal Form), we know that we should put items and pictures in their own tables. Here is what I assume would be correct. table Item int idItem (primary key) String itemName table Picture int idPicture (primary key) varchar(45) fileName long size int idItem (foreign key) Here is my question: If you are making Hibernate mapping files for these objects. In the data design, your Picture table needs a column to refer to the Item, so that a foreign key relation can be maintained. However,in your business domain objects - your Picture does not hold a reference/attribute to the idItem - and does not need to know it. A java Picture instance is always instantiated inside an Item instance. If you want to know the Item that the Picture belongs to you are already in the correct scope. Call myItem.getIdItem() and myItem.getItemPictures(),and you have the two pieces of information you need. I know that Hibernate tools have a generator that can auto make your POJO's from looking at your database. My problem stems from the fact that I planned out the data design for this experiment/project first. Then when I went to make the domain java objects, I realized that good design dictated that the objects hold other objects in a nested way. This is obviously different from the way that a database schema is - where all objects(tables) are flat and hold no other complex types within them. What is a good way to reconcile this? Would you: (A) Make the hibernate mapping files so that Picture.hbm.xml has a mapping to the POJO parent's idItem Field (if it's even possible) (B) Add an int attribute in the Picture class to refer to the idItem and set it at instantiation, thus simplifying the hbm.xml mapping file by having all table fields as local attributes in the class (C) Fix the database design because it is wrong, dork. I'd truly appreciate any feedback

  • How does this XPATH query differentiate?

    - by Soham
    I am kind of repeating this question because mostly due to my own ignorance, I could not fully understand the innards. Given this HTML snippet <td valign=top class="tim_new"><a href="/stocks/company_info/pricechart.php?sc_did=MI42" class="tim_new">3M India</a></td> <td class="tim_new" valign=top><a href='/stocks/marketstats/indcomp.php?optex=NSE&indcode=Diversified' class=tim>Diversified</a></td> How does this XPATH //a[@class='tim_new'] differentiate between line 1 and line 2.

  • Replacing deprecated <:< Manifest type witness in Scala 2.10

    - by Josh
    Can someone point me at what I should be doing under scala 2.10 in place of this deprecated type witness on Manifest? reflect.ClassManifest.singleType(foo) <:< barManifest Honestly, my goal here is just to replace it with something that doesn't raise a deprecation warning. I'm happy to use the new reflection API. Here's the code in question in context, if that's important: https://github.com/azavea/geotrellis/blob/master/src/main/scala/geotrellis/feature/op/geometry/geometry.scala#L45

  • Which is clearer form: if(!value) or if(flag == value) ?

    - by CodexArcanum
    I understand this is a subjective question, so I apologize if it needs to be closed, but I feel like it comes up often enough for me to wonder if there is a general preference for one form over the other. Obviously, the best answer is "refactor the code so you don't need to test for falsehood" but sometimes there's no easy way to do so and the "else" branch is simply to continue processing. So when you must have an "if not false" construct, which is the preferred standard: The not operator if(!value) Or the test for false if(value == false)

  • The links within posts should open a tab [closed]

    - by XGreen
    I couldn't find a place to feedback about this so apologies if I shouldn't have post this as a question here. Would it be possible for the admins of the site to change the links we post in our answers to have their target as _blank. It is quite hard when it is _self as we look at those urls in correlation with what the post is about so I wouldn't want it to replace the post.

  • When learning C, should one only refer to resources published from 2007 onward?

    - by Adam Siddhi
    I ask this question because the international standardization subcommittee for programming languages, or ISO/IEC JTC1/SC22 Programming languages, states on this page: http://www.open-std.org/JTC1/SC22/WG14/www/standards that Technical Corrigendum 3, the latest one, was published in 2007. Now I take it that this means the C language it self was changed and that the books and tutorials pre-2007 may contain outdated information. Please correct me if I am wrong. Thanks, Adam

  • converting rgb values to System.Drawing

    Hi, I've looked around, but don't see this question - maybe its too easy, but I don't have it. If I have file containing color values like: 255, 65535, 65280 ( I think this is green) is there a way to either: convert these to a System.Drawing.Color type or....better yet.. have .NET accept them as is to represent the color? thanks,
