  • $_SERVER['HTTP_X_REQUESTED_WITH'] seemingly not available on PHP 5.1.6

    - by kenny99
    Hi, I've run into a problem on a server running php 5.1.6 - the code i use to detect ajax requests isn't working as the $_SERVER['HTTP_X_REQUESTED_WITH'] variable is missing from the $_SERVER array. The same code works fine on php 5.2 and in firebug i can see the headers include X-Requested-With XMLHttpRequest. Anyone know any more about this issue and how I can get round it? Thanks in advance.

  • Integrate website backend with forum software?

    - by Msencenb
    I am designing a php/mysql website that will have a members are and a separate "forum" section. Should I just use the forum software as my "login/registration"? If this is the case should I go with VBulletin, Invision, phpBB3 or something different? Or should I roll my own single sign on hack? Or something completely different?

  • Automatically select option from select menu with link

    - by Ben
    Hello there, I am trying to use php (and if not php, javascript) to link to a page and include a "?type=foo" or "#foo" at the end of the link so that when the linked page loads it will automatically select a specific option, depending on the end of the link, from a dropdown menu in a form. I have tried to search for this but do not know what this action is actually called, but I've seen it done before. Does anyone know how to achieve this? Thanks very much.

  • How to give you website customers a secure feeling

    - by Saif Bechan
    I was wondering how you can give your website customers the confidence that you are not tinkering with the database values. I am planning on running a website which falls in the realm of an online game. There is some kind of credit system involved that people have to pay for. Now I was wondering how sites like this ensure there customers that there is no foul play in the database itself. As I am the database admin i can pretty much change all the values from within without anyone knowing i did. Hence letting someone win that does not rightfully is the winner. Is it maybe an option to decrypt en encrypt the credits people have so i can't change them. Or is there maybe a company i can hire that checks my company for foul play.

  • Can I create object names from a text file in Python 2.7?

    - by user560100
    I'm working on a game project. I've created an object, Star(Object). I want to assign the name of the variables, dynamically, from a text file. If I have a text file with: Sol Centauri Vega I want the program to create the Star(Object) with variable names from the text file. I want the process automated, because I'm looking to create hundreds of stars. I could write the code out by hand: Sol = Star(Sol) Centauri = Star(Centauri) Vega = Star(Vega) But isn't there a way to automate this? Essentially, what I eventually want is a tuple with the list of stars, as their own objects. Then, when I am doing game maintenance, I can just iterate over all the objects in the tuple.

  • How would I go about sharing variables in a class with Lua?

    - by Nicholas Flynt
    I'm fairly new to Lua, I've been working on trying to implement Lua scripting for logic in a Game Engine I'm putting together. I've had no trouble so far getting Lua up and running through the engine, and I'm able to call Lua functions from C and C functions from Lua. The way the engine works now, each Object class contains a set of variables that the engine can quickly iterate over to draw or process for physics. While game objects all need to access and manipulate these variables in order for the Game Engine itself to see any changes, they are free to create their own variables, a Lua is exceedingly flexible about this so I don't forsee any issues. Anyway, currently the Game Engine side of things are sitting in C land, and I really want them to stay there for performance reasons. So in an ideal world, when spawning a new game object, I'd need to be able to give Lua read/write access to this standard set of variables as part of the Lua object's base class, which its game logic could then proceed to run wild with. So far, I'm keeping two separate tables of objects in place-- Lua spawns a new game object which adds itself to a numerically indexed global table of objects, and then proceeds to call a C++ function, which creates a new GameObject class and registers the Lua index (an int) with the class. So far so good, C++ functions can now see the Lua object and easily perform operations or call functions in Lua land using dostring. What I need to do now is take the C++ variables, part of the GameObject class, and expose them to Lua, and this is where google is failing me. I've encountered a very nice method here which details the process using tags, but I've read that this method is deprecated in favor of metatables. What is the ideal way to accomplish this? Is it worth the hassle of learning how to pass class definitions around using libBind or some equivalent method, or is there a simple way I can just register each variable (once, at spawn time) with the global lua object? What's the "current" best way to do this, as of Lua 5.1.4?

  • Code Own Socket Server or Use Red5/ElectroServer on Amazon EC2?

    - by Travis
    I've been thinking for a long time about working on a multiplayer game in Flash. I need updates frequently enough that ajax requests won't work so I need to use a socket server. The system will eventually have enough objects/players that I would consider it an MMO. I would like to set up a scalable system on Amazon's EC2. (Which probably effects my choice of server) This architecture would hopefully allow the game to grow without many changes over time. (Using a domain decomposition technique or something similar) Heres my internal debate: Should I a. Code my own socket server in C++ or Java? b. Use the free and open source Red5 socket server for Flash? or c. Pay the licensing fees and go for Electroserver? I consider myself a decent developer, but am at an impasse as to what road to go down. I'm not sure if I, could develop/would need, the features of one of the prepackaged socket servers. I'm also not sure if the prepackaged servers would work well in an Amazon EC2 environment and take full advantage of its features. Any help or guidance would be greatly appreciated.

  • how to place last div into right top corner of parent div? (css)

    - by Radek
    can I somehow using css place the block2 in right top corner of block1? Note that block2 must be the (very) last inside html code of block1 or it could be placed after block1. I cannot make it the first element in block1 <html> <head> <style type="text/css"> .block1 {color:red;width:100px;border:1px solid green;} .block2 {color:blue;width:70px;border:2px solid black;position:relative;} </style> </head> <body> <div class='block1'> <p>text</p> <p>text2</p> <div class='block2'>block2</DIV> </div> </body> </html>

  • A free Step by Step guide to learning Sparx Enterprise Architect

    - by Yogi Yang 007
    I have just downloaded Sparx Enterprise Architect 7.5 but unfortunately I am not able to find a getting started guide or something like that. I have gone through official site of Sparx but there is not step by step guide to learning Sparx EA. I want a guide that will implement a small project and give instructions step by step so that I can understand and try out Sparx EA. I did find a few sites selling step by step guides but at this point of time I do not want to spend money on them.

  • How can I make a steady automata in JavaScript?

    - by RobertWHurst
    I'm working on a JavaScript game and I've got an automata system controlling game time and sprite animation as well as giving a hand to the path finding system for timing and such. My problem is on slow browsers the JavaScript loop I'm using for counting the time is not very accurate. It tends to jump around a lot. I there a way to force the loop to run consistently at 30 fps? The automata can drop frames if it needs to catch up so if the solution requires dropping frames that's ok.

  • Scalable Ticketing / Festival Website

    - by Luke Lowrey
    I've noticed major music festivals (at least in Australia) and other events that experience a peak in traffic when tickets go on sale have huge problems keeping their websites running well. I've seen a few different techniques used to try combat this such as short sessions and virtual queues but they dont seem to have much effect. If you were to design a website to sell a lot of tickets in a short amount of time how would you handle scalability? What technologies and programming techniques would you use?

  • Daemon with Clojure/JVM

    - by Isaac Copper
    I'd like to have a small (not doing too damn much) daemon running on a little server, watching a directory for new files being added to it (and any directories in the main one), and calling another Clojure program to deal with that new file. Ideally, each file would be added to a queue (a list represented by a ref in Clojure?) and the main process would take care of those files in the queue on a FIFO basis. My question is: is having a JVM up running this little program all the time too much a resource hog? And do you have any suggestions as to how go about doing this? Thank you very much!

  • Options to develop professionally with Microsoft tools and Technologies without spending a lot?

    - by iama
    I would like to develop applications for the Windows platform & at the very least I need a server based Windows OS (2008), SQL Server, IIS and Visual Studio. Looks like VS2010 professional alone will cost over $1K. Is there a cheaper option to get hold of Microsoft software? I remember long time ago there was an MSDN subscription option which allowed user access to server based OS and other server applications with restrictive licensing that was cost effective. I don't see that option anymore. Moreover, I am not a student & I understand Microsoft provides software at discounted rates for students. Any pointers? Many thanks.

  • Any book on designing and implementing a CRPG engine?

    - by Fabzter
    Hi! First, let me tell you, I am not really interested in making my own rpg engine (at least not in the near future, hehe), but I do feel like I want to understand the internals of how a rpg engine works. Why? Well, because I like to read about programming and design, It keeps me motivated and excited, and because I know I will learn a lot, for, even when I have been programming for some years now, I never stop considering myself an ignorant... there are simply SO many things involving a game engine (specially rpg ones, like branching storylines, and items and economics!) I'm eager to know. I've been searching (and thus, finding) lots of info online, but it is never focused in what I'm interested (most of it talks about the mathematics and AI algorithms implementation, which I know quite well), which is the design of overall structure, patterns, scripting engine, decision engine... damn, so many things I can't even imagine, since I've never done any game programming. I hope you know have an idea of how I feel, and how I want to learn for the sake of learning, and why would I want you to tell me if you know if there exist books touching the topics that interest me the most.

  • How to make an image randomizer from gallery directory?

    - by zebraman
    Hello, I would like to make a image randomizer/slider that randomly displays an image from a designated gallery and has controls to view the next/previous image. I have seen this done where images must be coded into arrays, but I would like to be able to just drop images into a /img/gallery directory and have the randomizer/slider pull random images from that directory. Could anyone offer some guidance on how to do this, possibly using jQuery, or refer me to a tutorial that does something like this?

  • Rhapsody TestConductor Experiences

    - by vaiomike
    I was wondering whether anybody out there is actively using Rhapsody TestConductor? Or has tried it for a while, but then decided to turn it down for a particular reason? If so, what are your experiences, in which field do you apply it, what are the shortcomings, or why did you turn it down? At the moment we're considering TestConductor as our tool of choice for testing as it's already integrated into Rhapsody, and would like to find out how applicable it is to our project (btw, we're using Rhapsody 7.4 in C). P.S: Recommendations on good books about Model Based Testing are also appreciated.

  • CSS Centering Issue - Div Centering appx 15px too far to the right

    - by Sootah
    I have a theme that I'm modifying for my site. I currently have it live on my test domain while I tinker with it before launch. http://www.networkgenius.org The #content-wrap div is centering, but too far to the right for some reason. I've absolutely no idea why it's doing this, especially since everything else is centering properly. What is the problem? I did add a 15px padding to the content-wrap area as I've changed the body's background color to the grey that you see and obviously didn't want the text pressed right up against the edges of the wrapper. Thanks for your help! -Sootah

  • I wanted to be a programmer

    - by Henrik P. Hessel
    Hello, let me ask your opinion. I'm 25 now, living in Germany. I started with QBASIC, did some Java in Highschool, and after School I created some Websites in PHP. Now, because my Company is Microsoft Gold Partner, I've to use Microsoft all the time. C#, MSSQL, ASPX and Sharepoint <- I really hate it! So, in my spare I concentrate to gain more knowledge (C++, Java, Silverlight or WPF), because it feels that I'm so far behind, in comparison for example to you guys, or other older employees in my company. Do think that my behaviour is useful? Should I focus my time to become i.e. a pure C# Programmer? I did C# even before I started to learn some C++. Should I learn what do with pointers, memcpy and stuff like that, even if managed code brings us so much benefits? Or is it a waste of time, better invested in learning the latest technologies? rAyt

  • Create method to handle multiple types of controls

    - by Praesagus
    I am trying to create a method that accepts multiple types of controls - in this case Labels and Panels. The conversion does not work because IConvertible doesn't convert these Types. Any help would be so appreciated. Thanks in advance public void LocationsLink<C>(C control) { if (control != null) { WebControl ctl = (WebControl)Convert.ChangeType(control, typeof(WebControl)); Literal txt = new Literal(); HyperLink lnk = new HyperLink(); txt.Text = "If you prefer a map to the nearest facility please "; lnk.Text = "click here"; lnk.NavigateUrl = "/content/Locations.aspx"; ctl.Controls.Add(txt); ctl.Controls.Add(lnk); } }

  • Machine restricted login access

    - by Sunil Shenoy
    I am working on a project that has a requirement such that login details can only be accessed from one machine at one time. For example, if I grant you access to my website and you login from your home machine, the system will store this settings in a cookie/database. Now if you try the same login details on your work machine or any other machine, the system will not let you log into the system. The login will now only work from home machine. Any suggestions on how to achieve this would be helpful. Any resources you can point me towards would also be appreciated.
