• 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

• How do I setup FitNesse for use with .NET?

  - by Fredrik

  I'm trying to get started with FitNesse for .NET on Windows Vista. In all tutorials I find on the web I'm told to execute the run.bat file, but all i get when downloading the latest release is a .jar-file. When i run this, the filestructure is unpacked and I can reach the fitnesse server by browsing to http://localhost. Now, when I'm trying to set up a test project, according to all documentation I find I'm supposed define the path to fitsharp.dll but I can't find this file anywhere in the filestructure that was set up from the .jar-file. What am I doing wrong? Sincerely, Fredrik

• CSS inheritance, aliases and other cool stuff

  - by emzero

  The other day I was randomly browsing the web and I found some program that lets you write CSS aliases and other cool stuff (which I can't remember right now). As an example, I remember you can do something like this: .myclass { background-color: red; greenfont } where greenfont was defined somewhere else as somekind of alias greenfont { color: green; } Then the program will generate the resulting CSS based on the alias and other stuff. Does anyone has used this? Or did I dreamed about it? I cannot find it now :P

• URL Routing with WebForms, what to do with additional querystrings like page number, filter, etc?

  - by Scott

  I am switching from Intelligencia's UrlRewriter to the new web forms routing in ASP.NET 4.0. I have it working great for basic pages, however, in my e-commerce site, when browsing category pages, I previously used querystrings that were built into my pager control to control paging. An old url (with UrlRewriting) would be: http://www.mysite.com/Category/Arts-and-Crafts_17 I have a MapPageRoute defined in global.asax as: routes.MapPageRoute("category-browse", "Category/{name}_{id}", ~/CategoryPage.aspx"); This works great. Now, somebody clicks to go to page 2. Previously I would have just tacked on ?page=2 as the querystring. Now, How do I handle this using web forms routing? I know I can do something like: http://www.mysite.com/Category/Arts-and-Crafts_17/page/2 But in addition to page, I can have filters, age ranges, gender, etc. Should I just keep defining routes that handle these variables, or should I continue using querystrings and can I define a route that allows me to use my querstrings like before?

• MVC2 Annotations dll not found by VS2008 compiler, how do I make it look in the right place?

  - by Paul Connolly

  I have VS2008 SP1 running with .NET 3.5 SP1 I have MVC2 running (with MVC1 uninstalled) All works ok except when I call the System.Components.DatAnnotations.dll, then the compiler complains of not being able to find it. Message is: Could not load file or assembly 'System.ComponentModel.DataAnnotations, Version=99.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. I tried repairing and reinstalling SP1 of both VS and .Net framework. I also tried referencing the assembly by browsing to it in the Reference assemblies in Programs directory. I have tried out most of the Google search result forum results but to no avail, I think it may be something simple which I have over looked. Any ideas?

• Google Chrome - NETWORK_IP_ADDRESSES_CHANGED - pages only partially load

  - by Julian

  Hi Google Chrome version (8.0.552.224 (Official Build 68599)) I have developed a web site using asp.net mvc and jquery. it uses a lot of ajax. I noticed that occasionally a web page does not complete loading all files from the server. Browsing through forums It seems that this also happens to other people. Looking in to the Chromium Net-Internals ( type: chrome://net-internals/ as a url in the chrome browser ) I noticed that the pages do not complete loading if a NETWORK_IP_ADDRESSES_CHANGED event occurred. Any files that were not fetched from the server before the time of the NETWORK_IP_ADDRESSES_CHANGED event failed to arrive with error (-3) Do you know why the NETWORK_IP_ADDRESSES_CHANGED event occurs? Is there a way to stop it from happening? Thanks and be happy, Julian

• How can I put all twill commands together into one piece of code in a .py file?

  - by brilliant

  Hello everybody! I have just started exploring TWILL. Twill is an amazing scripting language for Web browsing and it does all I want!!! So far I've been using twill from a Python shell (IDLE (Python GUI) to be precise) and I do things in the way of executing commands one by one (I mean, I type one command, run it, then type the next command): But I don't know how to put all these commands together in one .py file, so that they would all be executed one by one automatically. It seems that there is such possibility in twill. This example from the twill documentation page (you can see it HERE) shows us one piece of code consisting of several commands: So, my question is: How can I put all commands together in twill?

• FBA site owner encounter access deny in sharepoint 2007

  - by intangible02

  I created a sharepoint 2007 publishing site first using windows authentication, then extended it to another site using FBA. I created a FBA user and set it as site collection admin as well as top site owner. I also make application pool which the FBA site is running in to run with a user account which is within administrator group. But I encounter access deny error when browsing certain links using this site owner account. Is there other settings I need to configure? I found in the web.config, the impersonation is set to true. How does this affect the access rights?

• ASP.NET MVC Validation of ViewState MAC failed

  - by Kevin Pang

  After publishing a new build of my ASP.NET MVC web application, I often see this exception thrown when browsing to the site: System.Web.Mvc.HttpAntiForgeryException: A required anti-forgery token was not supplied or was invalid. --- System.Web.HttpException: Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. --- System.Web.UI.ViewStateException: Invalid viewstate. This exception will continue to occur on each page I visit in my web application until I close out of Firefox. After reopening Firefox, the site works perfectly. Any idea what's going on? Additional notes: I am not using any ASP.NET web controls (there are no instances of runat="server" in my application) If I take out the <%= Html.AntiForgeryToken % from my pages, this problem seems to go away

• System.Net.WebProxy in .NET Client

  - by NealWalters

  I don't yet have a good understanding of how the network is set up at my current client, but here is my issue. The vendor has a normal URL, but it might be a leased line. I have a .NET program that calls an external .asmx service. If I go to IE, Connections, LAN Settings, and uncheck "Automatic detect settings" and uncheck "Use Automatic Configuration Sript", then the .NET program runs and access the web service fine. But then, to access internet again from the browser, I have to re-check the two boxes, and so on throughout the day while we are testing and browsing. I'm hoping to put some code like this in the .NET program to avoid us having to constantly change: if (chkUseProxy.Checked) { myclient.Proxy = new System.Net.WebProxy(""); } I tried null and empty string and so far not able to connect without errors. Is this possible, and if so, what might be the correct parms for the constructor? Or are there other objects or properties that would need to be set? Thanks, Neal Walters

• ShoutCast over SSL

  - by Honus Wagner

  So I've gone ahead and set up my ShoutCast server DNAS and set my DSP in Winamp on my host computer. The server listens on port 8000, so per some instructions I installed an output plugin for winamp (Shoutcast DSP) and used 8000 and the password to connect. Server accepts the connection. Now, what the heck do I do now? My host computer is SSL secured and the DNAS server is installed within the secure web directory (if that matters). My desired end result is that I want to listen to my ShoutCast setup at home (host computer) from any computer. I try browsing to my ip address and port 8000 (without using HTTPS) and it comes back with nothing. If I browse with HTTPS://my.server.com:8000, I get Error code: ssl_error_rx_record_too_long) Have I completely missed something, or am I just a total moron? Thanks.

• Python utf-8 decoding issue with hashlib.digest() method

  - by Sorw

  Hello StackOverflow community, Using Google App Engine, I wrote a keyToSha256() method within a model class (extending db.Model) : class Car(db.Model): def keyToSha256(self): keyhash = hashlib.sha256(str(self.key())).digest() return keyhash When displaying the output (ultimately within a Django template), I get garbled text, for example : ?????_??!`?I?!?;?QeqN??Al?'2 I was expecting something more in line with this : 9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08 Am I missing something important ? Despite reading several guides on ASCII, Unicode, utf-8 and the like, I think I'm still far from mastering the secrets of string encoding/decoding. After browsing StackOverflow and searching for insights via Google, I figured out I should ask the question here. Any idea ? Thanks !

• How to access SharePoint files and folders from outside SharePoint?

  - by Ken Paul

  I need to programatically interface with SharePoint folders, files and lists from outside SharePoint. Most tutorials focus on working within SharePoint itself, or at least on the same server where SharePoint is installed. I need to automate some tasks from completely different servers -- tasks that require reading SharePoint lists, browsing folders, checking files out and in, reading files stored in SharePoint libraries, etc. It used to be easy using UNC folder and file paths. Now many of our SharePoint sites don't allow UNC access (probably for good reasons), but my needs are the same. What languages / libraries / interfaces will allow this? I'd like to be able to do this from server-side .NET code and from PowerShell scripts (not on the SharePoint server). Thanks for any pointers.

• Creating an iphone book application

  - by ennuikiller

  I have some experience creating iphone applications and would now like to create an iphone book application. Browsing the Book category in iTunes it seems to there is a standard format for building these apps, however, googling for how to build an iphone book app produces no useful results. This type of application is also not addressed in any of the iphone development books I've seen. Is there a standard method fot building these book applications? Or is it simply copying the text is some format (pdf, txt, html?) and then writing a document handling api? It seems there already must exist apis for doing this. Can anyone point me in the right direction. Thanks in advance!

• Launch IE with specific BHO enabled

  - by watsonmw

  I have a IE BHO plugin that I only want to be enabled when the user launches IE from my program (The program start IE using CreateProcess()). I don't want this BHO to be enabled when a user launches IE from outside my program, as that would mean any problems in the BHO could potentially mess up the user's normal browsing experience. What's the best way to do this? One way would be to register the BHO, launch IE and then quickly unregister the BHO. This seems kind of messy though, as a crash in the program that launches IE could cause the BHO to remain registered.

• Initialize Pointer Through Function

  - by SoulBeaver

  I was browsing my teacher's code when I stumbled across this: Order* order1 = NULL; then order1 = order(customer1, product2); which calls Order* order(Customer* customer, Product* product) { return new Order(customer, product); } This looks like silly code. I'm not sure why, but the teacher initialized all pointers to NULL instead of declaring them right away(looking at the code it's entirely possible, but he chose not to). My question is: is this good or acceptable code? Does the function call have any benefits over calling a constructor explicitely? And how does new work in this case? Can I imagine the code now as kind of like: order1 = new Order(customer, product);

• Corporate Wiki Organization - Technical Documentation

  - by Dave Jarvis

  Corporations have documents describing various aspects of their technical systems, including: Custom Applications Custom Development Frameworks Third Party Applications Accounting Bug Tracking Network Management How To Guides User Manuals Software Tools Web Browsers Development IDEs Graphics GIMP xv Text Editing File Transfer ncFTP WinSCP Hardware Servers Web Database Exchange File Network Devices Printers What other items are missing from the list, and how would you organize it? (For example, would Software Tools make more sense under Third Party Applications?) Try to think about where you, a software developer, would expect to find the information by browsing (not searching). A few constraints: The structure should not go beyond three levels deep. Avoid the word "and" in favour of two different categories. Keep the structure general: it should appy as broadly as possible. Target audience is primarily technical.

• Within a category, "Seach all posts" checkbox, how to?

  - by benoror

  Hi, I have set up my routes so I can search all posts with: /posts/search/foobar or search inside a category /posts/category/1/search/foobar It works pretty well, when someone is browsing an specific category it does search just posts that belongs to that category. When inside a category, I want to place a checkbox to "Search all the posts" My search form: <% form_for :posts, :url => {:controller => :posts, :action => :index} do |f| %> Search: <%= f.text_field :search %> <% if params[:cat] %> <%= f.check_box :ignore_cat, '1', false %> Search all the posts? <% end %> <%= f.submit 'Go' %> <% end %> How can I force to change the route?

• How do I change a Git remote HEAD to point to something besides "master"

  - by jhs

  Short version: How do I set a Git remote's HEAD ref to point to something besides "master"? My project has a policy not to use a "master" branch (all branches are to have meaningful names). Furthermore, the canonical master repository is only accessible via ssh://, with no shell access (like GitHub or Unfuddle). My problem is that the remote repository still has a HEAD reference to refs/heads/master, but I need it to point to a different branch. This is causing two problems: When cloning the repo, there this, warning: remote HEAD refers to nonexistent ref, unable to checkout. That's confusing and inconvenient. The web-based code browser depends on HEAD as a basis for browsing the tree. I need HEAD to point to a valid branch, then.

• How come ftp protocol produces transmission errors sometimes if the data is using TCP, which is checksummed?

  - by Cray

  Every once in a while, downloading (especially large) files through ftp will produce errors. I am guessing that's also partly the reason why all major sites are publishing external checksums along with their downloads. How is this possible if ftp goes through TCP, which has checksum inbuilt and resends data if it is transmitted corruptly? One could argue that this is due to the short length of the CRC in the TCP protocol (which is 16bit I think, or something like that), and the collisions are simply happening too often. but 1) for this to be true, not only must there be a CRC collision, but also the random network error must modify both the CRC in the packet, and the packet itself so that the CRC will be valid for the new packet... Even with 16 bitCRC, is that so likely? 2) There are seemingly not many errors in, say, browsing the web which also goes through TCPIP.

• IE 8 Caching Problem

  - by Jeff Catania

  One of my javascript sources had an extra comma that was throwing an error in IE8. So I opened up my editor, deleted the comma, and saved. I reloaded IE8, but it was still pulling the old js file. I deleted everything in "Delete Browsing History...", and restarted the browser. It is still pulling the old file. I even set up a log on my server to show whenever the js file was requested. When reloading with IE, the js file is never requested. I tried doing the same process in Chrome and FF, and it pulled the new file and logged properly on the server. Is there some other cache that I am failing to clear in IE that would cause this problem?
