  • How to avoid MissingMethodException?

    - by Dimitri C.
    If .NET 3.5 is installed, but not .NET 3.5 SP1, WaitHandle.WaitOne(int) throws a MissingMethodException. I'd like to be notified earlier on if the correct version of the .NET libraries is not available, for example when the application is started. Is this possible? Update: So my question question is twofold: a) How can I determine which version of the .NET library is required by an application? b) How can I determine the currently installed version of the .NET library?

  • In-line assembly

    - by aCuria
    For the below code, if i want to convert the for loop to in-line assembly, how would it be done? (Pardon the weird code, i just made it up.) 1) This is for the x86, using visual studio 2) This is a "how to use in line assembly" question, not a "how to optimize this code" question 3) Any other example will be fine. I will think of some better example code in abit.

  • Is the set of data always normalized in one form or the other in Databases

    - by manugupt1
    Suppose I have a set of data, given the data and the relation schemas can I assume that the set of data is normalized in one form or the other. In my opinion raw data given, has to be normalized into some form. However a discussion with a friend has led to ask me this question here. To expound more on the question, I would say given a set of functional dependencies for a relation or table, is it guaranteed that the table would atleast be in 1NF if not others

  • Simple popup java form with at least two fields

    - by nunos
    This is, I suppose, a very simple question for any Java programmer. My question is as simple as this: When the user clicks a button, I want to show a popup form that should have at least two JTextFields and two JLabels, so using JOptionPane.showInputDialog is not a possibility. Thanks.

  • Is it possible to implement Separated Interface in PHP?

    - by sunwukung
    I recently asked a question regarding the resolution of dependencies between Unit of Work and Data Mapper classes: http://stackoverflow.com/questions/3012657/dependency-injection-and-unit-of-work-pattern - (which was answered by Gabor de Mooij - thx) In PoEAA, Martin Fowler suggests using Separated Interface to manage these dependencies. My question is simple - is it actually possible to implement this pattern in PHP, or is it specific to Java interfaces? I've searched high and low and it's hard to find references to this pattern anywhere outside of PoEAA.

  • Opengl Coordinate System

    - by praveen
    Say I am using an Identity Matrix for my modelViewTransformation Matrix on an Open GL ES2.0 program. The Co-ordinate system in this case is the canonical opengl co-ordinate system which extends from (-1,-1,-1) to (1,,1,1). My question is, is this coordinate system right-handed or left-handed? A broader question: Is there a document with OpenGL which can list all the mathematical conventions followed by the API?

  • Which dll's are required to run osql.exe as a standalone?

    - by chama
    According to the accepted answer to this question, the osql.exe utility can be run as a standalone program on a computer without SQLServer, simply by copying the binary file to the new computer. My question is, however, which other files need to be copied along with osql.exe for it to work? Thanks so much!

  • How to write a spinlock without using CAS

    - by Martin
    Following on from a discussion which got going in the comments of this question. How would one go about writing a Spinlock without CAS operations? As the other question states: The memory ordering model is such that writes will be atomic (if two concurrent threads write a memory location at the same time, the result will be one or the other). The platform will not support atomic compare-and-set operations.

  • Execute function every nth second

    - by timkl
    Total JacaScript n00b question right here: I've made this snippet that clicks a link after 10th second: function timeout() { window.setTimeout(function() { $('img.left').click(); }, 1000); setTimeout("timeout()", 1000); } timeout(); My question is, how do I execute this function every 10th second, instead of just once? Is this the best way to do this, or is there some kind of nifty jQuery method that you prefer?

  • Why increased pipeline depth does not always mean increased throughput?

    - by worlds-apart89
    This is perhaps more of a discussion question, but I thought stackoverflow could be the right place to ask it. I am studying the concept of instruction pipelining. I have been taught that a pipeline's instruction throughput is increased once the number of pipeline stages is increased, but in some cases, throughput might not change. Under what conditions, does this happen? I am thinking stalling and branching could be the answer to the question, but I wonder if I am missing something crucial.

  • Meta Search Engine Architecture

    - by Loki
    The question wasn't clear enough, I think; here's an updated straight to the point question: What are the common architectures used in building a meta search engine and is there any libraries available to build that type of search engine? I'm looking at building an "enterprise" type of search engine where the indexed data could be coming from proprietary (like Autonomy or a Google Box) or public search engines (like Google Web or Yahoo Web).

  • Weird syntax for extending jQuery

    - by cantabilesoftware
    I recently saw this code on another post ( http://stackoverflow.com/questions/499126/jquery-set-cursor-position-in-text-area ) new function($) { $.fn.setCursorPosition = function(pos) { // function body omitted, not relevant to question } } (jQuery); After too long trying to understand what it was doing I finally figured out that it's just creating a new function with a parameter $ and then invoking it with jQuery as the parameter value. So actually, it's just doing this: jQuery.fn.setCursorPosition = function(pos) { // function body omitted, not relevant to question } What's the reason for the original, more confusing version?

  • Double paging definition

    - by Albinoswordfish
    This is not a programming question but more of an operating system question Right now I'm trying to learn what exactly Double paging means. I see two different terms, double paging on disk and double paging in memory. Apparently this problem arises when we introduce a buffer cache to store disk blocks when doing File I/O But I'm not really sure what exactly this term means. If anybody could specify it would be very helpful.

  • A list vs. tuple situation in Python

    - by Alphonse
    Is there a situation where the use of a list leads to an error, and you must use a tuple instead? I know something about the properties of both tuples and lists, but not enough to find out the answer to this question. If the question would be the other way around, it would be that lists can be adjusted but tuples don't.

  • How does Android emulator performance compare to real device performance?

    - by uj2
    I'm looking into writing an Android game, tough I don't curerntly own an Android device. For those of you who own a device, how does the performance on the emulator relate to real device performance? I'm especially interested in graphics related tasks. This obviously depends on both the machine running the emulator, and the specific device in question, but I'm talking rough numbers here. This question is a duplicate, but since that post is heavily outdated, I figured it's irrelevant by now.

  • Integration of aadvark with Gtalk - how does it work

    - by Gublooo
    Hi guys Not sure if anyone has used aadvark but it has a very nice integration with Gtalk. If you have signed up on aadvark - when any question is posted in your area of expertise - there will be nice pop-up in ur gtalk window asking if you are interested in answering - if you say Yes - it will ask you the question and you can answer in that window itself. Is that something they are able to do because Google bought them or does google have an API with which we can integrate it with our application to do something similar. Thanks
