  • ASP.Net Cross Page Posting

    - by John
    Currently I have two pages: The first page contains an input form, and the 2nd page generates an excel document. The input form's button posts to this 2nd page. What I'd like to do is add a second button which also posts to the 2nd page; however, I'll need requests created from this new button to act differently, which brings me to my question: Is there a way I can tell, from the 2nd page, which button was pressed to submit the request? The main reason I'm asking is I'd like to re-use the 2nd page's logic in parsing the information from the first page if possible; I'd rather not have to copy it to a new page and have the new button post to that. Thanks!

  • Cross-platform and language (de)serialization

    - by fwgx
    I'm looking for a way to serialize a bunch of C++ structs in the most convenient way so that the serialization is portable across C++ and Java (at a minimum) and across 32bit/64bit, big/little endian platforms. The structures to be serialized just contain data, i.e. they're pure data objects with no state or behavior. The idea being that we serialize the structs into an octet blob that we can store in a database "generically" and be read out later on. Thus avoiding changing the database whenever a struct changes and also avoiding assigning each data member to a field - i.e. we only want one table to hold everything "generically" as a binary blob. This should make less work for developers and require less changes when structures change. I've looked at boost.serialize but don't think there's a way to enable compatibility with Java. And likewise for inheriting Serializable in Java. If there is a way to do it by starting with an IDL file that would be best as we already have IDL files that describe the structures. Cheers in advance!

  • Simple cross platform GUI app

    - by Joe Cannatti
    I would like to know if there is any way that I could build a very simple GUI app (it doesn't even have to look good) that will run on a fresh install of Windows Vista and OS X with no other installations needed by the user. I would perfer not to use Java (just out of personal programming preference). I will use it though, if it is the only way. Specically, I am wondering if I can write a swing app with Scala or Groovy and run in on windows without them having to install anything. Sorry if this is a silly question, I am a Obj-C developer by trade.

  • Cross-Domain iframe communication

    - by Chris
    I have an iframe being created on a page, and the page's domain is being explicitly set to 'xyz.com' but the iframe's domain is defaulting to 'dev.xyz.com', which is the actual domain i'm developing for. The problem is, when I try to access that iframe via iframe.contentWindow.document, it fails due to the difference in domain. I've tried setting the iframe's src to a file with document.domain = 'xyz.com' but that doesn't seem to be doing the trick... Any ideas?

Note: I cannot use .remove() method.

  • Cross-compiling a Python script on Linux into a Windows executable

    - by Chinmay Kanchi
    I have a Python script that I'd like to compile into a Windows executable. Now, py2exe works fine from Windows, but I'd like to be able to run this from Linux. I do have Windows on my development machine, but Linux is my primary dev platform and I'm getting kind of sick of rebooting into Windows just to create the .exe. Any ideas? PS: I am aware that py2exe doesn't exactly compile the python file as much as package your script with the Python interpreter. But either way, the result is that you don't need Python installed to run the script.

  • How cross-platform .Net framework really is?

    - by Ivan
    What is normally to be done to run a WinForms application on a Mac or Linux machine? a. Just copy and run (assuming they have a Framework installed). b. Rebuild. c. Cosmetic source code modifications. d. Heavy source code modifications and forms redesign. Assuming that the application is developed as 100% managed C# 3 code by means Visual C# Express or Visual Studio 2008 targeting .Net Framework 3.5, developed without using any 3-rd party components/libraries, without encapsulating nonmanaged code or any low-level hacks - only standard Microsoft-documented .Net Framework C# API used). Or the same conditions but C# 4 language, .Net Framework 4 and Visual Studio 2010.

  • Easiest way to retrieve cross-browser XmlHttpRequest

    - by HeavyWave
    What is the easiest and safest way to retrieve XmlHttpRequest object that works across all browsers? Without any extra libraries. Is there a code snippet you use often? P.S. I know there are tons of examples on the net, but this is precisely the reason I am asking: there are too many different examples, and I just want something simple and proven to work.

  • Storing a file in the user's directory in cross-platform Java

    - by dalyons
    I have a Java application that runs on Mac and Windows, directly off a CD/DVD with no installation. Now, I need to store a file containing per-user data (think favourites etc.) somewhere on the local file system, so that it can be written to. So, where do you think is a good location for this file? I am thinking something like: <USER_DOCUMENTS_AND_SETTINGS>/application data/myapp/favourites.db for windows <USER_HOME_DIR>/.myapp/favourites.db for mac/nix Thoughts? And does anyone know the best way to determine these paths within Java?

  • Cross-Browser jQuery text-zoom implementation

    - by JMC Creative
    I've got some code to increase/decrease font size. This is giving me a headache because each browser seems to implement the $.css('font-size') differently (see jquery bug). The part that's really killing me, though, is that Firefox is scaling up okay, but when I use the scale down function below, it scales up. Webkit & IE are both working as expected. Any ideas on that? I put this in a fiddle here: http://jsfiddle.net/srQ3P/1/ where you can see it working as expected, and you can see it broken in firefox at the project page: http://cumberlandme.info/residents MAJOR EDIT Sorry, the issue is not the code, it's firefox buggy behavior. After I zoom in or out with the browser controls (ctrl + plus or ctrol + minus) the js goes haywire. This doesn't happen in other browsers. This is the real issue. Any advice on that

  • Create cross platform Java SWT Application

    - by mchr
    I have written a Java GUI using SWT. I package the application using an ANT script (fragment below). <jar destfile="./build/jars/swtgui.jar" filesetmanifest="mergewithoutmain"> <manifest> <attribute name="Main-Class" value="org.swtgui.MainGui" /> <attribute name="Class-Path" value="." /> </manifest> <fileset dir="./build/classes" includes="**/*.class" /> <zipfileset excludes="META-INF/*.SF" src="lib/org.eclipse.swt.win32.win32.x86_3.5.2.v3557f.jar" /> </jar> This produces a single jar which on Windows I can just double click to run my GUI. The downside is that I have had to explicitly package the windows SWT package into my jar. I would like to be able to run my application on other platforms (primarily Linux and OS X). The simplest way to do it would be to create platform specific jars which packaged the appropriate SWT files into separate JARs. Is there a better way to do this? Is it possible to create a single JAR which would run on multiple platforms?

  • Sinatra, JavaScript Cross-Domain Requests JSON

    - by pex
    I run a REST-API build on top of Sinatra. Now I want to write a jQuery Script that fetches data from the API. Sinatra is told to response with JSON before do content_type :json end A simple Route looks like get '/posts' do Post.find.to_json end My jQuery script is a simple ajax-call $.ajax({ type: 'get', url: 'http://api.com/posts', dataType: 'json', success: function(data) { // do something } }) Actually everything works fine as long as both runs on the same IP, API and requesting JS. I already tried to play around with JSONP for Rack without any positive results, though. Probably I just need a hint how to proceed.

  • Cross-platform editing for LaTeX documents?

    - by pufferfish
    What solutions are there for working on a LaTeX document on both Windows and Linux? It's a large document, and I will be working daily on both platforms so compatibility is essential if it's two different pieces of software. Bonus points for a solution that includes easy previewing.

  • cross domain DOM access and manipulation in Java ?

    - by gaqer
    In my Java app, how can I incorporate the browser (which loads and renders URLs) in Swing and access it's DOM and manipulate HTML ? How can you embed such browser in a Rich Internet Application and access it's DOM ? More specifically, Vaadin ? Is there a HTTP proxy class that can load an external URL, and render it to the user ? This was what I was doing on LAMP stack....but I want to switch to Vaadin or some Java web framework where I can just use Java to do everything from server-side to client-side logic design, so I can focus more on application logic. (aka looking for developer friendly frameworks like Vaadin). Thank you and have a great weekend !

  • What's your favorite cross domain cookie sharing approach?

    - by Haoest
    I see iframe/p3p trick is the most popular one around, but I personally don't like it because javascript + hidden fields + frame really make it look like a hack job. I've also come across a master-slave approach using web service to communicate (http://www.15seconds.com/issue/971108.htm) and it seems better because it's transparent to the user and it's robust against different browsers. Is there any better approaches, and what are the pros and cons of each?

  • Free PHP framework/library for single-sign on / cross domain login

    - by Dennis Cheung
    I am looking for free (non GPL is better) SSO framework/library implementation or code samples. There are many kind of SSO implementation. Sharing cookie, sharing session, one time token, associative accounts, etc, etc. (BTW, any good article compare them?) Is there any keyword I should google and reuse before before I start to implement our own wheel. I know OpenID, but which is too much and it is not our need. We rather keep it KISS. We just want share the credentials of user that could save users from another login form.

  • cross-browser Onunload and Onbeforeunload ? (particularly opera 11)

    - by user393087
    I have a form and I must notice user with alert() on exiting page while there are data in the form that had not been send. I've read that opera has a lot of problems with this. Opera 11 that is, because I need take into account only last version. So again, the alert should display on refresh, closing a tab, or closing whole browser. It would be nice to set event directly to the <form> element that would be launched on anything that leads to destroying this element.

  • Would there be a market for this idea (cross platform VM for iPhone OS)

    - by Tzury Bar Yochay
    For a long time I wondered if the following idea worth a nickel or just a waste of time and energy. I am willing to start a project which will provide a kind of a VM for all iPxxx apps - so developed once for iPxxx can run on a Macbook, iMac, Linux, Android and windows (desktop and mobile). You get the idea, right? I want to do to the current iPhone SDK, the same as what Mono did to Microsoft .Net and perhaps a more complete set of implementation. I tend to believe that if overnight all apps on appstore become available on the android market as well that would be a mini revolution. Think about running iPad apps on every tablet that will come out to the market in the future. Wouldn't it be fantastic to all the developers, which from now on, can write once and sell everywhere? The main questions which I ask myself repeatedly is: "Is This Legal?" - I mean, say I have done this, would apple's lawyers will start sending me all kinds of nasty emails? I am willing to hear your opinion about this idea as well as if some of you willing and able to join forces and start this open source project.
