  • [Raise|Trigger|Fire|...] an event?!?

    - by winSharp93
    Hello, in a German programming forum we currently have a discussion about events and what you (grammatically) do with them. The MSDN talks about "Event Raising" and "to raise an event". Thus, this seems to be one possibility. Are there any other synonyms? What about "to trigger an event" and "to fire an event"? A Google search will bring results for all of the three possibilities. This, however, does not mean that they are correct, too, of course. Are they? Are there any (stylistic, ...) differences or are they used in different contexts? Many thanks in advance for ending a heated debate :-)

  • Binding Javascript Event Handlers to a an Ajax HTML Response?

    - by John
    Let's say I have the following HTML code <div id="outer"> <div id="inner">Hello World</div> </div> At the end of my HTML page, I use javascript to attach event handlers like so, document.getElementById('inner').onclick = function() {alert(this.innerHTML);} document.getElementById('outer').onclick = function() { /* An Ajax Call where the response, which will be a string of HTML content, then goes into document.getElementById('outer').innerHTML */ document.getElementById('inner').onclick = function() {alert(this.innerHTML);} } In the above code, I am expecting <div id="inner">Hello World 2</div> to come back which requires me to re-attach the onclick event handler. This makes sense because the new response coming back is just a string, and I have to tell the browser that after converting to DOM, i also need some event handlers So my question is, is there a better way to manage event handlers on AJAX response that contains HTML content? I could use inline javascript within the html response, but then it prevents me from achieving non-intrusive javascript. So is there a way to achieve non-intrusive javascript and an efficient way to "maintain" event handlers of ajax html responses?

  • How to create custom MouseEvent.CLICK event in AS3 (pass parameters to function)?

    - by fromvega
    Hello, This question doesn't relate only to MouseEvent.CLICK event type but to all event types that already exist in AS3. I read a lot about custom events but until now I couldn't figure it out how to do what I want to do. I'm going to try to explain, I hope you understand: Here is a illustration of my situation: for(var i:Number; i < 10; i++){ var someVar = i; myClips[i].addEventListener(MouseEvent.CLICK, doSomething); } function doSomething(e:MouseEvent){ /* */ } But I want to be able to pass someVar as a parameter to doSomething. So I tried this: for(var i:Number; i < 10; i++){ var someVar = i; myClips[i].addEventListener(MouseEvent.CLICK, function(){ doSomething(someVar); }); } function doSomething(index){ trace(index); } This kind of works but not as I expect. Due to the function closures, when the MouseEvent.CLICK events are actually fired the for loop is already over and someVar is holding the last value, the number 9 in the example. So every click in each movie clip will call doSomething passing 9 as the parameter. And it's not what I want. I thought that creating a custom event should work, but then I couldn't find a way to fire a custom event when the MouseEvent.CLICK event is fired and pass the parameter to it. Now I don't know if it is the right answer. What should I do and how?

  • Can you install the Unicenter Event Agent on a Windows 2008 server?

    - by hsatterwhite
    I'm trying to install just the Unicenter Event Agent on a Windows 2008 virtual server, but every time I run the NSM 11.2 installer I get the following error code: Unknown or bad error code from "cadepchkx.exe" error code = -1 There are already some Unicenter agents installed on this server, but that was done from a custom install script. Has any one experienced this or know how I can get the installer to run properly, so I can install the event agent?

  • Do game-theoretic considerations stand in the way of this market-based game-mechanic achieving its goals?

    - by BerndBrot
    Mechanic The mechanic is called "market manipulation" and is supposed to work like this: Players can enter the London Stock Exchange (LSE) LSE displays the stock prices of 8 to 10 companies and derivatives. This number is relatively small to ensure that players will collide in their efforts to manipulate the market in their favor. The prices are calculated based on real world prices of these companies and derivatives (in real time) any market manipulations that were conducted by the players any market corrections of the system Players can buy and sell shares with cash, a resource in the game, at current in-game market value Players can manipulate the market, i.e. let the price of a share either rise or fall, by some amount, over a certain period of time. Manipulating the market requires spending certain in-game resources and is therefore limited. The system continuously corrects market manipulations by letting the in-game prices converge towards their real world counterparts at a rate of 2% of the difference between the two per hour. Because of this market correction mechanism, pushing up prices (and screwing down prices) becomes increasingly difficult the higher (lower) the price already is. Goals Players are supposed to collide (and have incentives to collide) in their efforts to manipulate the market in their favor, especially when it comes to manipulation efforts by different groups. Prices should not resolve around any equilibrium points. The more variance the better. Band-wagoning should always involve risk (recognizing that prices start rising should not be a sure sign that they will keep rising so that everybody can make easy profits even when they don't manipulate the market themselves) Question Are there any game-theoretic considerations that prevent the mechanic from achieving these goals?

  • Woes of a Junior Developer - is it possible to not be cut out for programming?

    - by user575158
    (Let me start off by asking - please be gentle, I know this is subjective, but it's meant to incite discussion and provide information for others. If needed it can be converted to community wiki.) I recently was hired as a junior developer at a company I really like. I started out in the field doing QA and transitioned into more and more development work, which is what I really want to end up doing. I enjoy it, but more and more I am questioning whether I am really any good at it or not. Part of this is still growing into the junior developer role, I know, but how much? What are junior developers to expect, what should they be doing and not doing? What can I do to improve and show my company I am serious about this opportunity? I hate that I am costing them time by getting up to speed. I've been told by others that companies make investments in Junior devs and don't expect them to pay off for a while, but how much of this is true? There's got to be a point when it's apparent whether the investment will pay off or not. So far I've been trying to ask as many questions I can, but I've you've been obsessing over a simple problem for some time and the others know that, there comes a time when it's pretty embarrassing to have to get help after struggling so long. I've also tried to be as open to suggestion as possible and work with others to try to refactor my code, but sometimes this can be hard clashing with various team members' personal opinions (being told by someone to write it one way, and then having someone else make you rewrite it). I often get over-stressed and judge myself too harshly, but I just don't want to have to struggle the rest of my life trying to get things work if I just don't have the talent. In your experience, is programming something that almost everyone can learn, or something that some people just don't get? Do others feel this way, or did you feel that way when starting out? It scares me that I have no other job skills should I be unsuited for having the skills necessary to code well.

  • Delegates and Events in C#

    - by hakanbilge
    Events and their underlying mechanism "Delegates" are very powerful tools of a developer and Event Driven Programming is one of the main Programming Paradigms. Its wiki definition is "event-driven programming or event-based programming is a programming paradigm in which the flow of the program is determined by events?i.e., sensor outputs or user actions (mouse clicks, key presses) or messages from other programs or threads." That means, your program can go its own way sequentially and in the case of anything that requires attention is done (when an event fires) by somebody or something, you can response it by using that event's controller method (this mechanism is like interrupt driven programming in embedded systems). There are many real world scenarios for events, for example, ASP.NET uses events to catch a click on a button or in your app, controller has notice of a change in UI by handling events exposed by view (in MVC pattern). Delegates in C# C# delegates correspond to function pointers in  [read more....]

  • FIX: Visual Studio Post Build Event Returns &ndash;1 when it should not.

    - by ChrisD
    I had written a Console Application that I run as part of my post build for other projects..  The Console application logs a series of messages to the console as it executes.  I use the Environment.ExitCode value to specify an error or success condition.  When the application executes without issue, the ExitCode is 0, when there is a problem its –1. As part of my logging, I log the value of the exit code right before the application terminates.  When I run this executable from the command line, it behaves as it should; error scenarios return –1 and success scenarios return 0.   When I run the same command line as part of the post-build event, Visual Studio reports the exit code as –1, even when the application reports the exit code as 0.   A snippet of the build output follows: Verbose: Exiting with ExitCode=0 C:\Windows\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets(3397,13): error MSB3073: The command ""MGC.exe" "-TargetPath=C:\TFS\Solutions\Research\Source\Framework\Services\Identity\STS\_STSBuilder\bin\Debug\_STSBuilder.dll" C:\Windows\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets(3397,13): error MSB3073:  C:\Windows\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets(3397,13): error MSB3073: " exited with code -1. The Application returns a 0 exit code.  But visual studio is reporting an error.  Why? The answer is in the way I format my log messages.  Apparently Visual Studio watches the messages that get streamed to the the output console.  If those messages match a pattern used by visual studio to communicate errors, Visual Studio assumes an error has occurred in the executable and returns a –1.  This post details the formats used by Visual Studio to determine error conditions. In my case, the presence of the colon was tripping up Visual studio.  I Replaced all occurrences of colon with an equal sign and Visual Studio once again respected the exit code of the application. Verbose= Exiting with ExitCode=0 ========== Build: 3 succeeded or up-to-date, 0 failed, 0 skipped ==========

  • Why does SEO based code tips not appear to affect ranking?

    - by Ben
    I've been researching various methods for SEO where pages have precise titles, keywords are highlighted with h tags and tick the many boxes stated in good page mark up for SEO. However when looking at some top ranked search sites on google for key terms they have terrible SEO based mark up. Really long page titles, no tags, limited appearance of keywords in the text and so on. SEO analysis services rate them lower than other sites, yet these sites rank really high. Even with a low number of back-links they are high, so I don't understand how these sites earn the position when they appear inferior to those below them which have better mark up and links. I don't want to cause trouble my mentioning sites or keywords etc. but looking in google at 'executive search' the roughly 5th placed site makes no sense why it should be highly rank, especially with all the added .swfs. The same applies for the top of 'Japan Executive Search'. My main point is that these sites seem to not have all the important structural rules stated in seo page rating applications and general suggested best practice, nor do they show large back-links. It makes me feel like there is no point bothering to write decent mark up if it really doesn't matter. Can anyone explain how sites with such mark-up, and low back-links can outrank well written and structured sites with greater linkage? Sorry if this is a fuzzy question, I want to avoid singling out any sites for example, but it really has me perplexed that sites which appear to ignore the suggested best practices rank so well.

  • SFML programs fails to debug with glslDevil

    I'm testing the glslDevil debugger with a simple (and working) SFML application in Linux + NVidia. But it always fails in the window creation step: W!

  • D key not working on Ubuntu

  • How to create single integer index value based on two integers where first is unlimited?

    - by Jan Doggen
    I have table data containing an integer value X ranging from 1.... unknown, and an integer value Y ranging from 1..9 The data need to be presented in order 'X then Y'. For one visual component I can set multiple index names: X;Y But for another component I need a one-dimensional integer value as index (sort order). If X were limited to an upper bound of say 100, the one-dimensional value could simply be X*100 + Y. If the one-dimensional value could have been a real, it could be X + Y/10. But if I want to keep X unlimited, is there a way to calculate a single integer 'indexing' value from X and Y? [Added] Background information: I have a Gantt/TreeList component where the tasks are ordered on a TaskIndex integer. This does not need to be a real database field, I can make it a calculated field in the underlying client dataset. My table data is e.g. as follows: ID Baseline ParentID 1 0 0 (task) 5 2 1 (baseline) 8 1 1 (baseline) 9 0 0 (task) 12 0 0 (task) 16 1 12 (baseline) Task 1 has two baselines numbered 1 and 2 (IDs 8 and 5) Task 9 has no baselines Task 12 has one baseline numbered 1 (ID 16) Baselines number 1-9 (the Y variable from my question); 0 or null identify the tasks ID's are unlimited (the X variable) The user plays with visibility of baselines, e.g. he wants to see all tasks with all baselines labeled 1. This is done by updating a filter on the table. Right now I constantly have to recalculate TaskIndex after changing the filter (looping through records). It would be nice if TaskIndex could be calculated on the fly for each record knowing only the data in the current record (I work in Delphi where a client dataset has an OnCalcFields event handler, that is triggered for each record when necessary). I have no control over the inner workings of the visual component.

  • Restful Java based web services in json + html5 and javascript no templates (jsp/jsf/freemarker) aka fat/thick client

    - by Ismail Marmoush
    I have this idea of building a website which service JSON data through restful services framework. And will not use any template engines like jsp/jsf/freemarker. Just pure html5 and Javascript libs. What do you think of the pros and cons of such design ? Just for elaboration and brain storming a friend of mine argued with the following concerns: sounds like gwt this way you won't have any control over you service api for example say you wanna charge the user per request how will you handle it? how will you control your design and themes? what about the 1st request the browser make? not easy with this all of the user's requests will come with "Accept" header "application/json" how will you separate browser from abuser? this way all of your public apis will be used by third party apps abusively and you won't be able to lock it since you won't be able to block the normal user browser We won't use compiled html anyway but may be something like freemarker and in that case you won't expose any of your json resources to the unauthorized user but you will expose all the html since any browser can access them all the well known 1st class services do this can you send me links to what you've read? keep in mind the DOM based XSS it will be a nightmare ofc, if what you say is applicable.

  • What are the advantages of programming to under an OS as opposed to bare metal executive?

    - by gby
    Assume you are presented with an embedded system application to program, in C, on a multi-core environment (think a Cavium or Tilera) and need to choose between two environments: Code the application under Linux in SMP mode or code the application under a thin bare metal executive (something like a very minimal RTOS), perhaps with a single core running UP Linux that can serve control tasks. For the purpose of this question, assume that both environment provide the same level of performance guarantees in any measurable aspects of run time performance, including number of meaningful action per second, jitter, latency, real time considerations - the works. (and yes, I realize this is by far not a trivial assumption at all, bare with me). How would you justify going with a Linux SMP based solution rather then a bare metal thin executive solution? The question may seems silly. It certainly seems obvious to me - but I have to convince someone that does not think the same. Could you help make a list of arguments in favor of choosing a real SMP aware OS (Linux) vs. a bare metal executive assuming performance guarantees are NOT an issue? Many thanks

  • Algorithm for dynamically calculating a level based on experience points?

    - by George
    One of the struggles I've always had in game development is deciding how to implement experience points attributed to gaining a level. There doesn't seem to be a pattern to gaining a level in many of the games I've played, so I assume they have a static dictionary table which contains experience points vs. the level. e.g. Experience Level 0 1 100 2 175 3 280 4 800 5 ...There isn't a rhyme or reason why 280 points is equal to level 4, it just is. I'm not sure how those levels are decided, but it certainly wouldn't be dynamic. I've also thought about the possibility of exponential levels, as not to have to keep a separate lookup table, e.g. Experience Level 0 1 100 2 200 3 400 4 800 5 1600 6 3200 7 6400 8 ...but that seems like it would grow out of control rather quickly, as towards the upper levels, the enemies in the game would have to provide a whopping amount of experience to level -- and that would be to difficult to control. Leveling would become an impossible task. Does anyone have any pointers, or methods they use to decide how to level a character based on experience? I want to be fair in leveling and I want to stay ahead of the players as not to worry about constantly adding new experience/level lookups.
