• VB.NET/C# Comparison Operator for to test for set membership - like the IN Operator for SQL...

  - by Albert

  so in SQL you can do something like: WHERE title IN('title1','title2','title3') to test for set membership. how can I do this in VB.NET/C#.NET? Example: IF textMyTitle.text IN ("title1","title2","title 3") THEN 'Take Action End If Obviously the IN part of that statement doesn't work...whats the logical equivalent in .NET?

• Method Vs Property

  - by obsoleteattribute

  Hi, I'm a newbie to .NET. I have a class called Project, a project can have multiple forecasts.Now If I want to check if the projects has any forecasts or not should I use a readonly boolean property called HasForecast() or should I use a method named HasForecast() which basically returns a boolean value.From framework design guidelines I came to know that methods should be used when the operation is complex,since here I'm retrieving the value of forecasts from DB should I consider method, or since it is a logical data member should I use a property.If I use a property can I call a method in DBLayer from its getter.Please explain Regards, Ravi

• iPhone init method return type

  - by William Jockusch

  Suppose we are writing a class (let's call it Class) in an iPhone program. In all the samples out there, the init methods are typically declared like this: -(id) initWithFoo: (Foo *) foo My question is: would it be more logical to do the following? Why or why not? -(Class *) initWithFoo: (Foo *) foo

• Home Interior Design Rules as an AI/Computer Intelligence problem?

  - by jsight

  Are there any sites out there that describe interior design principles in a really logical way? Eg, walkways should have a minimum width of xx Inches. I've done some googling, but most of the results are relatively generic (and spammy). Has there been solid research in this area that could lay the groundwork for automated assistants?

• Can you use "parenthesis" on Predicate operations

  - by fishtoprecords

  I can't see any way to build a Predicate that uses parenthesis to control logical order. Is there one? Say I want to do something like Predicate <= mumble and (foo or baz) A simple Predicates.and or a Predicates.or has no equivalent that says "foo or baz" and with mumble. Is this possible?

• Which parts of Graphics Pipelines are done using CPU & GPU?

  - by afriza

  Which parts of pipelines are done using CPU and which are done using GPU? Reading Wikipedia on Graphics Pipeline, maybe my question does not precisely represent what I am asking. Referring to this question, which "steps" are done in CPU and which are done in GPU? Edit: My question is more into which parts of logical high level steps needed to display terrain+3D models are using CPU/GPU instead of which functions.

• Is there a free pgp key dumping program?

  - by calccrypto

  is there any pgp key dumping program like http://www.pgpdump.net/ that also shows the MPI values as well as the other information? the linked website's program will print out ... for the long MPI, which is perfectly logical, but I want to see the values since my program is for some reason getting all but one part right (reading an elgamal public key), and its messing with everything that comes afterwards. i want to see where im off by a few bits

• Do Google Maps Flash API Markers fire an event when added to the stage?

  - by Alterscape

  With the Google Maps Flash API, I want to add an event listener which fires when the Marker is added to the Map using map.addOverlay(); Event.ADDED_TO_STAGE is not fired, though it seems logical. What are the alternatives?

• Encrypt column data with LINQ

  - by kape123

  I was wondering if there is easy solution to this or I'm stuck with following: When updating DB: dti.Pass = Crypter.Encrypt(dti.Pass); _db.SubmitChanges(); When selecting from DB: Data.DbTableItem dti = _db.Single(a=a.Id == id); dti.Pass = Crypter.Decrypt(dti.Pass); Meaning - I am not really into writing repetitive code and this seems like logical thing to be supported by LINQ; so I'm wondering if it is.

• <?php echo $questionTitle; ?> [closed]

  - by oil

  So this "question" makes no sense and will be closed. But are you willing to spend your hard-earned reputation to downvote it? Go on. A programmer should be able to make logical decisions, why will you downvote the question then instead of ignoring it?

• Getting key/value pairs from plist-style xml using simplexml in php

  - by Anthony

  Here is an example bit from the xml file: <array> <dict> <key>Name</key> <string>Joe Smith</string> <key>Type</key> <string>Profile</string> <key>Role</key> <string>User</string> <key>Some Number</key> <integer>1</integer> <key>Some Boolean</key> <true/> </dict> </array> I have two separate goals. The first is to extract an array from the dictnode that would look like: [Name] => Joe Smith [Type] => Profile [Role] => User [Some Number] => 1 [Some Boolean] => true It's not crucial that the boolean be included, so if that adds too much complexity, I'd rather just know how to deal with the others for now. The second goal is to be able to select the value node (<string>, <integer>,etc) so that I can change the value. I would need to select it based on the text value of the preceding key element. I think the following XPath should work: //key[.=$keyname]/following-sibling[1] But I'm not sure. Basically, this whole system that Apple uses seems logical, but totally contrary to the XML is supposed to work. If I ran the world, the original XML would look more like: <dict type="array"> <value key="Name" type="string">Joe Smith</value> <value key="Type" type="string">Profile</value> <value key="Role type="string">User</value> <value key="Some Number" type="integer">1</value> <value key="Some Boolean" type="boolean">true</value> </dict> But since it is fairly logical, I am wondering if I'm missing some obvious way of handling it.

• json specifies "any UNICODE character"?

  - by bukzor

  Maybe this is just my unfamiliarity with unicode, so please correct me if I'm mistaken. Looking at http://json.org/, the spec says that a string can include "any UNICODE character", but this confuses me. JSON is a communication format correct? At the core of it, everything must translate down to bytes. In contrast, UNICODE is a logical format and must be encoded to be able to transmit it, right? So what did they mean there?

• Would ViewModels fit in the Model View Presenter pattern?

  - by Jonn

  Having used ViewModels in MVC, I was wondering if applying the same to the MVP pattern is practical. I only have a few considerations, one being that MVP is already fairly hard to implement (with all the additional coding, not much on the seeming complexity) or that ViewModels already have a slightly similar way of modeling data or entities. Would adding another layer in the form of ViewModels be redundant or is it a logical abstraction that I, as one implementing the MVP pattern, should adhere to?

• Django: Sum on an date attribute grouped by month/year

  - by Sébastien Piquemal

  Hello, I'd like to put this query from SQL to Django: "select date_format(date, '%Y-%m') as month, sum(quantity) as hours from hourentries group by date_format(date, '%Y-%m') order by date;" The part that causes problem is to group by month when aggregating. I tried this (which seemed logical), but it didn't work : HourEntries.objects.order_by("date").values("date__month").aggregate(Sum("quantity"))

• prolog: reduce then write the value of a predicate

  - by jreid9001

  This is some of the code I am writing assert(bar(foo)), assert(foo(bar-5)), I'm not sure if it works though. I'm trying to get it to reduce foo by 5. I need a way to write the value of foo, but haven't found a way too. write('foo is' + foo) would be the logical way to me, but doesn't seem to work.

• C++ and,or,not,xor keywords [closed]

  - by uray

  Possible Duplicate: The written versions of the logical operators. I notice that C++ define keyword and, or, not, xor, and_eq, or_eq, not_eq and xor_eq as an alternative to &&, ||, !, ^, &=, |=, != and |=. and they're rarely used! What's wrong? Are they not portable?

• What means Zend_Mime::ENCODING_8BIT when sending mails with Zend_Mail?

  In the example for Zend_Mail on http://framework.zend.com/manual/en/zend.mail.attachments.html they use ENCODING_8BIT but searching for what that might be sends me to http://msdn.microsoft.com/en-us/library/ms526992%28EXCHG.10%29.aspx were (and this sounds logical to me) it is explained that 8bit encoding does not make sense for emails.

• improve javascript prototypal inheritance

  - by Julio

  I'm using a classical javascript prototypal inheritance, like this: function Foo() {} Naknek.prototype = { //Do something }; var Foo = window.Foo = new Foo(); I want to know how I can improve this and why I can't use this model: var Foo = window.Foo = new function() { }; Foo.prototype = { //Do something }; Why this code doesn't work? In my head this is more logical than the classical prototypal inheritance.

• Is there a suitable replacement for C++, when I would like to write video processing applications?

  - by Nisanio

  Hi I want to write a video editing software, and the "logical" conclusion is that the language I must to use is C++... But I don't like it (sorry c++ fans) I would like to write it with something cool, like Lisp or Haskell or Erlang... But I don't know if the open source implementation of those languages (I don't have money to buy licenses) let me made a competitive software (in the performance area) What do you think? what do you recommend?

• Adding multiple items in a batch to an osCommerce site?

  - by Unkwntech

  I need to add several hundred products to an osCommerce (ugh, I know, it wasn't my choice) but osCommerce doesn't have a built in method for this (or at least I couldn't find it), does anyone know where some (even half decent) documentation on HOW osCommerce stores products ('cause it certainly is not in any logical manner) can be found? Or possibly some free addon/software that will do it?

• Is there any way to group edit buttons in MediaWiki?

  - by Mark Robinson

  Is there any way to group the edit buttons displayed above the edit dialog in MediaWiki? By grouping, I mean like Word does (and even this editor) - you can add dividing lines to group them so that e.g. Bold and Italic are in one group, numbered list and bullet points in another. We've added lots of new buttons (in EditPage.php) and they are in a logical order, but at 30 buttons it is a bit overwhelming for some users.

• Why enabling transparency can lead to cliping problems ?

  - by Amokrane

  Hi, I'm working on a 3D graphical application in Java using the Java 3D API. I noticed that every time I was dealing with transparency, all I got in return were some clipping problems. Some parts of the scene weren't displayed properly. It might seem obvious that this would happen in a certain way but I'm looking for a logical explanation, why is this happening? Thank you
