  • Programmatically triggering events in Javascript for IE using jQuery

    - by Dan Herbert
    When an Event is triggered by a user in IE, it is set to the window.event object. The only way to see what triggered the event is by accessing the window.event object (as far as I know) This causes a problem in ASP.NET validators if an event is triggered programmatically, like when triggering an event through jQuery. In this case, the window.event object stores the last user-triggered event. When the onchange event is fired programmatically for a text box that has an ASP.NET validator attached to it, the validation breaks because it is looking at the element that fired last event, which is not the element the validator is for. Does anyone know a way around this? It seems like a problem that is solvable, but from looking online, most people just find ways to ignore the problem instead of solving it. To explain what I'm doing specifically: I'm using a jQuery time picker plugin on a text box that also has 2 ASP.NET validators associated with it. When the time is changed, I'm using an update panel to post back to the server to do some things dynamically, so I need the onchange event to fire in order to trigger the postback for that text box. The jQuery time picker operates by creating a hidden unordered list that is made visible when the text box is clicked. When one of the list items is clicked, the "change" event is fired programmatically for the text box through jQuery's change() method. Because the trigger for the event was a list item, IE sees the list item as the source of the event, not the text box, like it should. I'm not too concerned with this ASP.NET validator working as soon as the text box is changed, I just need the "change" event to be processed so my postback event is called for the text box. The problem is that the validator throws an exception in IE which stops any event from being triggered. Firefox (and I assume other browsers) don't have this issue. Only IE due to the different event model. Has anyone encountered this and seen how to fix it? I've found this problem reported several other places, but they offer no solutions: jQuery's forum, with the jQuery UI Datepicker and an ASP.NET Validator ASP.NET forums, bug with ValidatorOnChange() function

  • Running my web site in a 32-bit application pool on a 64-bit OS.

    - by Jeremy H
    Here is my setup: Dev: - Windows Server 2008 64-bit - Visual Studio 2008 - Solution with 3 class libraries, 1 web application Staging Web Server: - Windows Server 2008 R2 64-bit - IIS7.5 Integrated Application Pool with 32-bit Applications Enabled In Visual Studio I have set all 4 of my projects to compile to 'Any CPU' but when I run this web application on the web server with the 32-bit application pool it times out and crashes. When I run the application pool in 64-bit mode it works fine. The production web server requires me to run 32-bit application pool in 64-bit OS which is why I have this configured in this way on the staging web server. (I considered posting on ServerFault but the server part seems to be working fine. It is my code specifically that doesn't seem to want to run in 32-bit application pool which is why I am posting here.)

  • .pl or .cgi for perl web script file

    - by Nano HE
    HI. I created two files 'hello.pl' and 'hello.cgi' with the code below. #!/usr/bin/perl print "Content-type:text/html\n\n"; print "hello world"; I can view the page via both http://www.mydomain.com/cgi-bin/hello.pl and http://www.mydomain.com/cgi-bin/hello.cgi. Which one is more sense in Perl web dev? BTW, the directory of 'cgi-bin' created by my VPS server, Do I need contact with my VPS support to remove it or just remain it like this URL style? Maybe http://www.mydomain.com/perDev/hello.cgi is better?

  • Does Apache allow to authorize an HTTP request based on a result of a subrequest?

    - by Jan Wrobel
    I'm looking for an equivalent of nginx http auth request module but for Apache. For each incoming HTTP requests, the module sends a subrequests to authentication/authorization back-end. Th auth request carries a path and all headers of the original request. Based on the result of the auth request, the original requests is allowed (HTTP code 200), denied (HTTP code 403) or login is requested (HTTP code 401). Such a generic mechanism allows to build really flexible authentication and authorization schemes. Is something like this possible in Apache (likely with a help of some third party module)?

  • What is a good way to quantify C++ knowledge and skill?

    - by LoudNPossiblyRight
    I have only recently started to study (with the hopes of mastering) C++, one because i have started to love it and two because it's a good career/profession move. At the same time i wish to quantify my knowledge and skill so as to set my self apart from those who just throw C/C++ on their resumes and fish. Is there an open, industry and community recognized way of quantifying ones knowledge and skill in C++? I have looked at Brainbench, MS C++ certificates, and other online certification sites which offer to rate you at $50-$200 per test however there doesn't seem to be a standard on how to rate knowledge and skill. It's one thing for MS or Oracle/Sun to have certifications for their products but C++ is a standard, shouldn't there be a standard way or rating one's knowledge and skill there in? Thanks.

  • A two player game over the intranet..

    - by Santwana
    Hi everybody.. I am a student of 3rd year engineering and only a novice in my programming skills. I need some help with my project.. I wish to develop a two player game to be played over the network (Intranet). I want to develop a simple website with a few html pages for this.My ideas for the project run as follows: 1.People can log in from different systems and check who ever is online on the network currently. the page also shows who is playing with whom. 2.If a person is interested in playing with a player who is currently online, he sends a request of which the other player is somehow notified( using a message or an alert on his profile page..) 3.If the player accepts the request, a game is started. This is exactly where I am clueless.. How can I make them play the game? I need to develop a turn based game with two players, eg chessboard.. how can I do this? The game has to be played live.. and it is time tracked. i need your help with coding the above.. the other features i wish to include are: 4.The game could not be abruptly terminated by any one if the users.The request to terminate the game should be sent to the other player first and only if he accepts can the game be terminated. Whoever wins the game would get a plus 10 on their credit and if he terminated he gets a minus 10. The credits remains constant even if he loses but the success percentage is reduced. 6.The player with highest winning percentage is projected as the player of the week on the home page and he can post a challenge to all others.. I only have an intermediate knowledge of core java and know the basics of Swing and Awt. I am not at all familiar with networking in java right now. I have 5 to 6 weeks of time for developing the project but I hope to learn the things before I start my project. i would prefer to use a lan to illustrate the project and I know only java,jsp,oracle,html and bit of xml to develop my proj. Also I wish to know if I can code this within 6 weeks, would it be too difficult or complicated? Please spare some time to tell me. Please.. please.. I need your suggestions and help.. thank you so much..

  • Has anybody managed to teach themself strong OOP skills through mainly developing with JavaScript?

    - by yaya3
    I am trying to do this, I'm a full time front-end dev and am aware that I am struglling to achieve this. When I am referring to OOP skills I am referring to understanding and being familiar with concepts like inheritance, polymorphism, encapsulation, abstaction. I am aware that it may be more likely to achieve what I'm after by focusing on another language in my spare time. This is the plan, but I'd be really intrigued to hear if anybody has managed to achieve this purely through JavaScript and how you did it. It'd be even better to hear from strong OOP developers from who use different programming languages to know if they have worked with developers who have managed to achieve this.

  • Will a Ph. D. in Computer Science help?

    - by Francisco Garcia
    I am close to my 30s and still learning about programming and software engineering. Like most people who like their profession I truly believe that I should aim to improve and keep updated. One of the things I do is reading technical papers from professional publications (IEEE and ACM) but I admit there are very good bloggers out there too. Lately I started to think (should I say realize?) that Ph. D people actually are expected to expand constantly their knowledge, but little is expected from lower classes once they know enough This made me think that maybe having a Ph. D will help to have more... respect? but I also believe that I am already getting old for that. Futhermore I see many master and doctor programs that does not seem to add any value over hard experience and self learning. I belive that a degree in computer science, althought not necessary, can lay out a good base for programming work. However: What can a Ph. D. degree give you that you cannot learn on your own? (if you are not into something VERY specific and want to work in a non academic environment)

  • Net Neutrality FAIL [closed]

    - by leeand00
    I know I'll get into all kinds of trouble for bringing this up on SO, but considering that nearly all of us programmers depend on the Internet to get our jobs done, I really think it's worth looking into today's failure of our right to use the Internet by way of Lobbying ISPs. Although something tells me there will be retribution for the actions of the ISPs/tel cos/cable and their lobbyist since, lets face it...ISPs/Telcos didn't invent the Internet. I'm not going to be the one to do it, but um I think somebody already has...as everybody I talked to was having Internet connection problems today at work. Just thought this might be relevant to all of our jobs...in the U.S.A. at least. If you work at an Big evil ISPs, by all means...try and close this question. If you don't...and your just a chap who enjoys your Internet access...please RT this: Contact The Democrats Who Are Against Net Neutrality (Full List W/ Contact Info) http://bit.ly/aMSV0W #NetNeutralityFAIL net-neutrality

  • Which is the UI technology of the future considering: eye-candy-effect, interactivity (gestures, voc

    - by user193655
    If you had to write a next-gen application, in which on the surface (UI) you need some "futuristic features", by considering the following aspects which is the choice you'd make? 1) eye-candy: cool UI, 3D, Effects, nice graphics, sound transitions... 2) user interaction: not only mouse and keyboard but touch, voice and more.... + user interactivity aspect, which is the technology you'd choose? 3) X-platform: this is to have some X-platform discussion. Of course single platform technologies (as WPF) have may be some more power, anyway in a general discussion considering X-platform as a resource is important 4) available components: of course the coolest technology with no available components is may be an option for a component developer but not for an application developer My question is generic, but anyway * have in mind data-driven apps, not pure multimedia apps, videogames, ....

  • How should I manage/declare dependencies between open source C# projects?

    - by munificent
    I've got a game (a roguelike to be specific) in C# that I'm in the process of cleaning up to open source. One step I'd like to take is splitting it into three distinct pieces: A simple package of utility classes, things like 2D arrays, vectors, etc. A terminal UI package that gives you a curses-like display. It depends on 1. The actual game, which uses 1 and 2. Right now, these are all separate projects in the same solution, but I'd kind of like to make them completely separate projects (in the "open source project" sense, not the "visual studio project" use of the term) with their own names and repos. I think, at the very least, #1 is generally useful even if you aren't building game, and I don't want someone to have to build an entire game just to get some handy functions. What I'm not sure about is how to handle the dependencies if I split up the solution. If someone decides they want to sync the game, how should I ensure they also get 1 and 2? Include the built dependent .dlls in the games repo? Just document, "you need these other projects and they must be in a path relative to the game like this". Just leave it all one giant solution and a single repo. Something I'm not thinking of?

  • Do you think the AI industry will ever come back?

    - by Isaiah
    I just spent some time reading about the collapse of the AI industry and realized a lot of the reason it failed was because technology was slow to catch up with their theories on when it would be available. I also read that it is believed computers that will be able to emulate human synapses may be made round 2015-2025. It's 2010 now and were getting pretty close to that time frame. I was wondering if anyone thinks that the AI industry will return as the technology lands? And if so, will it change the language market? Could Lisp like languages suddenly experience a burst of growth if it does? Idk I just thought it was interesting thinking about it.

  • [JavaScript] How can I load static configuration information

    - by Goro
    In my code, I use JavaScript for UI and PHP for back end. I also use PHP to store application settings and sometimes my UI code needs to access this information. My configuration file looks something like this (config.php): $resolution_x = 1920; $resolution_y = 1080; etc... When I need to access any of these settings form JavaScript, i simply use to substitute the value directly, but it just doesn't strike me as very robust. Are they any dangers of doing this that I am not aware of? Is there a better way of doing this? Thank you,

  • Read -> change -> save. Thread safe.

    - by Pavel Alexeev
    This code should automatically connect players when they enter a game. But the problem is when two users try to connect at the same time - in this case 2nd user can easily overwrite changes made by 1st user ('room_1' variable). How could I make it thread safe? def join(userId): users = memcache.get('room_1') users.append(userId) memcache.set('room_1', users) return users I'm using Google App Engine (python) and going to implement simple game-server for exchanging peers given by Adobe Stratus.
