• Browser Detection Python / mod_python?

  - by cka

  I want to keep some statistics about users and locations in a database. For instance, I would like to store "Mozilla","Firefox","Safari","Chrome","IE", etc... as well as the versions, and possibly the operating system. What I am trying to locate from Python is this string; Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.14) Gecko/2009090216 Ubuntu/9.04 (jaunty) Firefox/3.0.14 Is there an efficient way to use Python or mod_python to detect the http user agent/browser?

• Viewing large text file in a browser

  - by MeLight

  Hi, I need to write a text file viewer (not the directory tree, but the actual file contents) for use in a browser. It will be used to view large files. I want to give the user the ability to actually ummm, browse the file, ie prev page & next page buttons, while each page will show only a portion of the file. Two question: Is there anyway to pass the file descriptor through POST (or something) so that on each page I can keep reading from an already open file, and not starting all over again (again - huge files) Is there a way to read the file backwards? Will be very useful for browsing back in a file. Any other implementation ideas are very welcome. Thanks

• Cross Browser Addons

  - by Paul Tarjan

  I'm looking to make a browser add-on as widely and easily distributable as possible. Is there a set of wrapper addons for all the major browsers that will let me write one piece of code and it can execute in any of the environments? I don't need anything fancy, just DOM and some ajax stuff. Something along the lines of greasemonkey for IE, FF, and Chrome would be nice. In the same vein, is there a way to link to my script so that it prompts for an install of greasemonkey (if it isn't installed) and then leads the script?

• browser ctrl-f find and non-visible text

  - by David Pilling

  Can the browser feature of contrl+F to find text be integrated with text in popup windows. I'd like to have some scientific reference information given when someone hovers over a species name in a web page. Generating the popup, tooltip style text is no problem, the problem is that anyone using Ctrl+F won't be able to find it, or if I position the text out of view when not required, it will be found but be invisible. The same sort of effect applies to "accordion" style expanding text areas. I'm looking for some sort of event generated when find is highlighting a result.

• HTTP MODULE Event Does Not Fire When Click Browser's Back Button

  - by Ali

  I Wrote an Http Module that checks if logged user is restricted disables images on the page. void application_AuthorizeRequest(object sender, EventArgs e) { . . . if (context.User.IsInRole("Restricted")) { context.Response.StatusCode = 401; context.Response.End(); } The code works fine. When the page loads, every image on the screen disapears. but when I go to another page and click back button on the browser and goto previous page images appear. What should I? (I dont want to clear Cache every time) context.Response.Cache.SetNoStore(); context.Response.Cache.SetCacheability(HttpCacheability.NoCache);

• Cross Browser Testing on Virtual Machines - Issues?

  - by codemate2112

  I am part of an organization in which there is contention amongst some very competent folks as to whether or not testing cross-browser behavior for JavaScript applications on virtual machines (for IE6/7/8, FF2/3, Chrome on XP/Vista/7) is reliable. This is using VMWare server on a Linux box host. While the discrepancies seen are few, there are cases in which it has proven difficult to tell if it is a product of virtualization or just different machine configurations. My question to the community is, what is people experience with this? Is there any credence to the claim that VM pose inconsistencies, or are they generally spot-on reliable? Can we trust them?

• Regex browser version match

  - by Matic

  I have a string: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729) I want to know what version of Firefox is in the string (3.5.2). My current regex is: Firefox\/[0-9]\.[0-9]\.[0-9] and it returns Firefox/3.5.2 I only want it to return 3.5.2 from the Firefox version, not the other versions in the string. I already know the browser is Firefox.

• Help with Event-Based Components

  - by Joel in Gö

  I have started to look at Event-Based Components (EBCs), a programming method currently being explored by Ralf Wesphal in Germany, in particular. This is a really interesting and promising way to architect a software solution, and gets close to the age-old idea of being able to stick software components together like Lego :) A good starting point is the Channel 9 video here, and there is a fair bit of discussion in German at the Google Group on EBCs. I am however looking for more concrete examples - while the ideas look great, I am finding it hard to translate them into real code for anything more than a trivial project. Does anyone know of any good code examples (in C# preferably), or any more good sites where EBCs are discussed?

• Detecting if a browser is using Private Browsing mode

  - by Steve

  I'm building an extranet for a company paranoid about security. They want to make sure that (among other things) their users are browsing the site with the Private Browsing mode switched on in their web browser so that no cookies or history is kept. I found only this http://jeremiahgrossman.blogspot.com/2009/03/detecting-private-browsing-mode.html and http://serverfault.com/questions/18966/force-safari-to-operate-in-private-mode-and-detect-that-state-from-a-webserver The ideal solution would use no or minimal javascript. Would attempting to set a unique cookie work for all browsers and platforms? Anyone done this before? thanks!

• Jquery: change event to input file on IE

  - by cmedeiros

  Hello guys, I already looked all around, and can't find a solution: I have a form to upload files, and it should fire the submit after the file selection. On FF/Chrome it goes weel, and submit the form after file selection, but I can't do this on ie. Already tried with click/propertychange but nothing happens. Some code I already tried: $("#attach").attr("onChange", "alert('I changed')"); $("#attach").live($.browser.msie? 'propertychange': 'change', function(e) { ... }); Any sugestions to I try? Thanks for any help Edit1: I think there's a important information, this input file, is created on the fly, because of it I use .live() to bind the event

• Embed remote desktop in browser

  - by Shaun_web

  I would like to embed a Remote Desktop session within my browser. I must use remote desktop because my clients can't install any additional software on the server. Here are some problems that I can already foresee: 1) I believe that I can embed an RDP ActiveX control, but then all I could support is IE. And even then, IE lockdown may forbid ActiveX controls. 2) I don't know anything about Apple computers, but I presume that they don't inherently run RDP? 3) I think there are ways to run RDP through a Java control. I don't have experience to know if this is a good or bad idea. I suppose that Java may even be disabled on some browsers, but don't know if this is a common case? So, what options have I got here to make this work reliably? I presume that I may need some default options (ie ActiveX), and then some fallback options (ie Java), and code to identify the correct option each time.

• Is loading a video in a browser multithreaded?

  - by mwilcox

  It's hard to know what is multithreaded in a browser and what isn't. It seems while a video streams or progressively downloads, it does not affect page performance, so my guess it is. Note I'm using Flash video, but it's really about video in general. Any other tips on what else is multithreaded (image loads?) is also helpful. I know JavaScript is not, and I thought Flash wasn't but I heard somewhere that it may be (or it could be done), but I think they were not well informed.

• Calling an svn update from a php script via a browser is not working

  - by hbt

  Hey guys, I have two scripts. running an update and calling shell_exec('svn update') and shell_exec('svn st') running a mysqldump shell_exec('mysqldump params') The svn script is not running the update command, the svn st is printing results but not the svn update I tried to declare parameters when calling svn update eg 'svn update ' . dir . ' --username myuser --password mypasswd --non-interactive'; -- still nothing Played with most of the params If this is something related to binaries/permissions/groups, I don't see it. The mysqldump command works fine and is producing a file, so why isn't the svn updating the filesystem? Please do not advise using core SVN classes in PHP. This is not an option, I don't have complete control over the server and the module is not available. Thanks for your help, -hbt PS: important thing to mention here. The scripts works when called via the command line. It only fails when called via a web browser.

• CSS cross browser compatibility on Ubuntu

  - by bhefny

  Hello, I'm currently working in web development and my default desktop is Ubuntu and I'm kind of happy with the setup and applications I got going. But I need to test web pages for cross browser compatibility while still being on Ubuntu. I have gone through hell trying to get IE7 or IE8 (with wine) to run on ubuntu and when they finally worked they were very buggy and the graphics/scrolling was insanely slow. Of course there is the option of virtual box but again, too much GBytes just to run a small application! So to all the CSS gurus out there, how can I continue with my beloved Ubuntu and still deliver a good quality (tested) page. Thank you.

• jQuery, Forms, Browser Refreshes

  - by Eric Cope

  I have a large form with some fields values dependent on previous elements. I use jquery's .trigger event to trigger the dependent field's update functions. When I refresh the page (click reload or click back), the previous values selected are still there, but the dependent fields are not reflecting the other element's values. How can I trigger the update functions upon refresh? I saw a way to prevent the browser from using the form's cached values. I'd rather use the cached values and update the elements dependent on the elements with cached values.

• 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.

• Images with unknown content: Dangerous for a browser?

  - by chris_l

  Let's say I allow users to link to any images they like. The link would be checked for syntactical correctness, escaping etc., and then inserted in an <img src="..."/> tag. Are there any known security vulnerabilities, e.g. by someone linking to "evil.example.com/evil.jpg", and evil.jpg contains some code that will be executed due to a browser bug or something like that? (Let's ignore CSRF attacks - it must suffice that I will only allow URLs with typical image file suffixes.)

• Browser, upload large file

  - by Mike

  I'm looking for a way to allow a user to upload a large file (~1gb) to my unix server using a web page and browser. There are a lot of examples that illustrate how to do this with a traditional post request, however this doesn't seem like a good idea when the file is this large. I'm looking for recommendations on the best approach. Bonus points if the method includes a way of providing progress information to the user. For now security is not a major concern, as most users who will be using the service can be trusted. We can also assume that the connection between client and host will not be interrupted (or if it is they have to start over).

• .NET Runtime Object Browser.

  - by user290907

  Is there a framework which can be used in your application, to make it expose internal objects on some port for inspection. for.e.g. after i start my application in this case a GUI Application, and then say launch http://localhost:9100 then it should show me the statistics of the app. I played a bit with HttpListener accepting connections and then outputting raw HTML, it works fine for simple tasks, but there is too much worked involved if i have make a proper object browser. Thanks in Advance.

• An XEvent a Day (31 of 31) – Event Session DDL Events

  - by Jonathan Kehayias

  To close out this month’s series on Extended Events we’ll look at the DDL Events for the Event Session DDL operations, and how those can be used to track changes to Event Sessions and determine all of the possible outputs that could exist from an Extended Event Session.  One of my least favorite quirks about Extended Events is that there is no way to determine the Events and Actions that may exist inside a Target, except to parse all of the the captured data.  Information about the Event...(read more)
