  • C++: Platform indepentend game lib?

    - by Martijn Courteaux
    Hi, I want to write a serious 2D game, and it would be nice if I have a version for Linux and one for Windows (and eventually OSX). Java is fantastic because of its platform independent. But Java is to slow to write a serious game. So, I thought to write it in C++. But C++ isn't very cross-platform friendly. I can find game libraries for Windows and libraries for Linux, but I'm searching one that I can use for both, by recompiling the source on a Windows platform and on a Linux platform. Are there engines for this or is this idea irrelevant? Isn't it that easy (recompiling)? Any advice and information about C++ libraries would be very very very appreciated!

  • Embed external website inside a page

    - by jasongullickson
    I'd like to load something from website B into a page on website A and contain the functionality of website B within a container on website A. I tried doing this using a div and jQuery's load() method but I run into cross-domain-scripting issues (I think, it works with a local file but not a remote URL). I also tried using an iframe but strange things happen (for example, when a link is clicked in the "contained" website B, it reloads the entire browser, losing the content of website A). I've read about some server-side ways of handling this (and it may just come to that) but ideally I want something completely client side, JavaScript and HTML. Any ideas?

  • Possible to use Javascript to access the client side's network(knowingly)

    - by Earlz
    I recently found an exploit in my router to basically give me root access. The catch? There is a nonce hidden form value that is randomly generated and must be sent in for it to work that makes it difficult to do "easily" So basically I'm wanting to do something like this in javascript: get http://192.168.1.254/blah use a regex or similar to extract the nonce value put the nonce value into a hidden field in the current page submit the form by POST to http://192.168.1.254/blah complete with the nonce value and other form values I want to send in. Is this at all possible using only HTML and Javascript? I'm open to things like "must save HTML file locally and then open", which I'm thinking is one way around the cross domain policy. But anyway, is this at all possible? I'm hoping for this to be able to run from at least Firefox and Chrome. The audience for this is those with some technical know how.

  • Do cross reference database tables have a place in domain driven design?

    - by Mike Cellini
    First some background. Let's say we have a system where a customer is placing an order in a web interface. The items that customer is ordering can priced in various ways. Sometimes including the cost of delivery and sometimes not at all. That pricing effectively depends on a variety of factors including the vendor's own pricing model, that vendor's individual contracts with customers as well as that vendor's contracts with its own suppliers. Let's assume that once a customer places an order for a particular item and chooses a contract if any, the method of delivery can be determined by variables on those contracts. Those delivery methods also live in their own table in the database and have various properties consumed downstream. It makes sense that a cross reference or lookup table would store that information. That table would be loaded into the domain and could then be used to apply the appropriate delivery method while processing the order. Does this make sense in the context of domain driven design? Or is my thinking too relational? Is this logic that should be built into it's own class/method (I mean beyond apply the cross reference table data)?

  • You cannot do cross joins in SQL Azure but there is a way around that....

    - by SeanBarlow
    So I was asked today how to do cross joins in SQL Azure using Linq. Well the simple answer is you cant do it. It is not supported but there are ways around that. The solution is actually very simple and easy to implement. So here is what I did and how I did it. I created two SQL Azure Databases. The first Database is called AccountDb and has a single table named Account, which has an ID, CompanyId and Name in it. The second database I called CompanyDb and it contains two tables. The first table I named Company and the second I named Address. The Company Table has an Id and Name column. The Address Table has an Id and CompanyId columns. Since we cannot do cross joins in Azure we have to have one of the models preloaded with data. I simply put the Accounts into a List of accounts and use that in my join.   var accounts = new AccountsModelContainer().Accounts.ToList(); var companies = new CompanyModelContainer().Companies; var query = from account in accounts             join company in                 (                       from c in companies                      select c                  ) on account.CompanyId equals company.Id             select new AccountView() {                                               AccountName = account.Name, CompanyName = company.Name,                                 Addresses = company.Addresses                         }; return query.ToList();   So as long as you have your data loaded from one of the contexts you can still execute your queries and get the data back that you want.

  • What is the right approach to checksumming UDP packets

    - by mr.b
    I'm building UDP server application in C#. I've come across a packet checksum problem. As you probably know, each packet should carry some simple way of telling receiver if packet data is intact. Now, UDP already has 2-byte checksum as part of header, which is optional, at least in IPv4 world. Alternative method is to have custom checksum as part of data section in each packet, and to verify it on receiver. My question boils down to: is it better to rely on (optional) checksum in UDP packet header, or to make a custom checksum implementation as part of packet data section? Perhaps the right answer depends on circumstances (as usual), so one circumstance here is that, even though code is written and developed in .NET on Windows, it might have to run under platform-independent Mono.NET, so eventual solution should be compatible with other platforms. I believe that custom checksum algorithm would be easily portable, but I'm not so sure about the first one. Any thoughts? Also, shouts about packet checksumming in general are welcome.

  • Communicate with the local machine from a web page

    - by Earlz
    Hello. We have a web application. There are physical devices that we need to be able to communicate with, and we have access to all of our clients computers to install whatever software we need. Now, for the question: Is there a way to make this browser-agnostic? As in, not requiring ActiveX controls? One of my ideas was to install a custom made webserver on each client and then have javascript on our webpage that communicates with that webserver. This could be done by the same way that http://earlz.biz.tm javascript can access subdomains assigned to 127.0.0.1 such as http://loopback.earlz.biz.tm The problem with this of course is that the client's custom made webserver would be forced to run on port 80(which will have conflicts at least sometimes), or we would have to use a nonstandard port for our web application, which is quite undesirable. Does anyone else have ideas on how to do this?

  • SmartGWT Program not displaying getting wnd.isc.Browser is null

    - by Holograham
    When running my gwt program in GWT Development Mode it fails to display showing this error in the console: com.google.gwt.core.client.JavaScriptException: (TypeError): '$wnd.isc.Browser' is null or not an object I do not believe the error is due to my project setup. Other member of the team can compile fine. It is most likely some type of config problem on my end. I have re-checked out the project and still get the error. I am using the latest jdk 1.6.0_19 if that matters

  • determine if javascript blur/focusout event is from selecting flash or leaving browser

    - by jedierikb
    In IE when I select flash, document.onfocusout is fired. When this event is fired, I would like to distinguish between selecting flash and leaving the browser. When I handle the callback, document.activeElement is the previous html element with focus (what I just left), so this is not helpful for solving this problem. Clearly there has been a change in focus to warrant calling the blur method -- is this information available somewhere? Or is there a better way to do this?

  • Javascript newbie, how to choose between window.URL.createObjectURL() and window.webkitURL.createObjectURL() based on browser

    - by Rohith Raveendran
    From the firefox developer website I know that firefox use objectURL = window.URL.createObjectURL(file); to get url of file type, but in chrome and other webkit browsers we have window.webkitURL.createObjectURL() for detecting url. I don't know how to swap this functions based on browser engines, and I need it to be worked on both browsers (Chrome and firefox) https://developer.mozilla.org/en/DOM/window.URL.createObjectURL

  • Why Do Browsers Leak Memory?

    - by Dane Balia
    A colleague and I were speaking about browsers (using browser control in a project), and it appears as plain as day that all browsers (Firefox, Chrome, IE, Opera) display the same characteristic or side-effect from their usage and that being 'Leaking Memory'. Can someone explain why that is the case? Surely as with any form of code, there should be proper garbage collection? PS. I've read about some defensive patterns on why this can happen from a developer's perspective. I am aware of an article Crockford wrote on IE; but why is the problem symptomatic of every browser? Thanks

  • How to use WatiN to control browser tabs?

    - by Dmitri Nesteruk
    I want to use WatiN with IE in a parallel setting, i.e. work with dozens/hundreds of pages at once. I've tried sticking it into a Parallel.For loop only to see the whole thing crash, so I'm thinking opening multiple tabs in the browser is the way to go. Can someone suggest how this can be done using WatiN (or just some IE-related API) or whether there's a better way? TIA!
