  • What is WCF (and pros and cons)?

    - by user279521
    I am trying to understand what is WCF, but can't get a visual understanding of how it adds value (reading msdn does'nt help). I have worked with COM in the past, and I know about webservices. Can someone shed some light on what is WCF and its pros and cons (maybe how it relates to COM or replaces COM etc)? Links to reference web sites would also be great. Thanks

  • Secure, simple php faq creating/editing scripts?

    - by Tchalvak
    I'm looking to build a simple site centered around a simple faq system in php. The faq concept is simple, but I want to have an administrative-access backend for editing and creating the entries, and securing a login seems more complex and time-consuming, so I'm looking for suggestions for code to start me off. Does anyone know of any open source php scripts or snippets that would work for administrative login to some php scripts that could be used as a simple faq system? Or both, the faq php code + web administrative access code?

  • UpdateProgress with UpdatePanel not showing up in User control when page is loading

    - by Carter
    Is this typical behavior of the UpdateProgress for an ASP.Net UpdatePanel? I have an update panel with the UpdateProgress control inside of a user control window on a page. If I then make the page in the background do some loading and click a button in the user control update panel the UpdateProgress does not show up at all. It's like the UpdatePanels refresh request is not even registered until after the actual page is done doing it's business. It's worth noting that it will show up if nothing is happening in the background. The functionality I want is what you would expect. I want to loader to show up if it has to wait for anything to get it's refresh done when after the button is clicked. I know I can get this functionality if I just use jquery ajax with a static web method, but you can't have static web methods inside of a user control. I could have it in the page but it really doesn't belong there. A full-blown wcf wouldn't really be worth it in this case either. I'm trying to compromise with an UpdatePanel but these things always seem to cause me some kind of trouble. Maybe this is just the way it works? Edit:So I'll clarify a bit what I'm doing. What's happening is I have a page and all it has on it are some tools on the side and a big map. When the page initially loads it takes some time to load the map. Now if while it's loading I open up the tool (a user control) that has the update panel in question in it and click the button on this user control that should refresh the update panel with new data and show the loading sign (in the updateprogress) then the UpdateProgress loading image does not show up. However, the code run by the button click does run after the page is done loading (as expected) and The UpdateProgress will show up if nothing on the page containing the user control is loading. I just want the loader to show up while the page is loading. I thought my problem was that perhaps the map loading is in an update panel and my UpdateProgress was only being associated with the update panel for the user control's update panel. Hence, I would get no loading icon when the map was loading. This is not the case though.

  • Use a subdirectory as root with htaccess in Apache 1.3

    - by Andrew
    I'm trying to deploy a site generated with Jekyll and would like to keep the site in its own subfolder on my server to keep everything more organized. Essentially, I'd like to use the contents of /jekyll as the root unless a file similarly named exists in the actual web root. So something like /jekyll/sample-page/ would show as http://www.example.com/sample-page/, while something like /other-folder/ would display as http://www.example.com/other-folder. My test server runs Apache 2.2 and the following .htaccess (adapted from http://gist.github.com/97822) works flawlessly: RewriteEngine On # Map http://www.example.com to /jekyll. RewriteRule ^$ /jekyll/ [L] # Map http://www.example.com/x to /jekyll/x unless there is a x in the web root. RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} !^/jekyll/ RewriteRule ^(.*)$ /jekyll/$1 # Add trailing slash to directories without them so DirectoryIndex works. # This does not expose the internal URL. RewriteCond %{REQUEST_FILENAME} -d RewriteCond %{REQUEST_FILENAME} !/$ RewriteRule ^(.*)$ $1/ # Disable auto-adding slashes to directories without them, since this happens # after mod_rewrite and exposes the rewritten internal URL, e.g. turning # http://www.example.com/about into http://www.example.com/jekyll/about. DirectorySlash off However, my production server runs Apache 1.3, which doesn't allow DirectorySlash. If I disable it, the server gives a 500 error because of internal redirect overload. If I comment out the last section of ReWriteConds and rules: RewriteCond %{REQUEST_FILENAME} -d RewriteCond %{REQUEST_FILENAME} !/$ RewriteRule ^(.*)$ $1/ …everything mostly works: http://www.example.com/sample-page/ displays the correct content. However, if I omit the trailing slash, the URL in the address bar exposes the real internal URL structure: http://www.example.com/jekyll/sample-page/ What is the best way to account for directory slashes in Apache 1.3, where useful tools like DirectorySlash don't exist? How can I use the /jekyll/ directory as the site root without revealing the actual URL structure? Edit: After a ton of research into Apache 1.3, I've found that this problem is essentially a combination of two different issues listed at the Apache 1.3 URL Rewriting Guide. I have a (partially) moved DocumentRoot, which in theory would be taken care of with something like this: RewriteRule ^/$ /e/www/ [R] I also have the infamous "Trailing Slash Problem," which is solved by setting the RewriteBase (as was suggested in one of the responses below): RewriteBase /~quux/ RewriteRule ^foo$ foo/ [R] The problem is combining the two. Moving the document root doesn't (can't?) use RewriteBase—fixing trailing slashes requires(?) it… Hmm…

  • ASP.net MVC 2 and MonoDevelop 2.2

    - by rifferte
    Is it possible to utilize MVC 2 from MonoDevelop 2.2 (using Mono 2.4)? If so - is it as simple as grabbing a reference to the new System.Web.Mvc or is there something else to consider? I realize that any templating support in MonoDevelop may not be 100% there since it was built to utilize MVC v1 (at least as of MonoDevelop 2.2). If anyone can add any other tips or tricks that would help as well.

  • Using regexkitlite with strings containing % signs

    - by David Liu
    So I'm using RegexKitLite in my iPhone app, and I'm basically grabbing out a bunch of URLs and names from within a web page. The problem is that whenever it comes across a URL with URL encoded characters like %22 for a double quote or %27 for a single quote, the captured string basically gives me a jumbled overflowed string, containing garbage and even method names. I'm really not doing anything particularly special within the regex, just your basic "startdelimiter(.*)enddelimiter" regex.

  • iphone Three20 TTMessageController Address Book

    - by Ward
    Hey there, I'm trying to use the TTMessageController from Three20 to send messages through a custom web service. I'm not clear on how I can incorporate contacts from the user's address book. I see the model mock address book in the sample app, but the sample only contains names. Is there a way to set the datasource of TTMessageController to be the address book? Thanks, Howie

    - by Aren B
    Finally broke down and seeking help, my client/iis (not sure which) usually times out after about 30s - 1 minute while im debugging (stepping through code) which not only causes me to lose my spot and have to start over (usually stepping faster, making more mistakes) but the IIS Debug session closes completely and I have to warm up the entire session again. What's the best way to get more time out of a debugging session? Debugging a vanilla 3.5 Web Site (not app) on IIS 7.5 Classic Pipeline

  • Why Rails.cache is not thread safe?

    - by Freewind
    I know Rails.cache is ActiveSupport::Cache::MemoryStore, and it is not thread safe. I don't understand, why rails use a thread-unsafe cache as its default? Why not use ActiveSupport::Cache::SynchronizedMemoryStore? In my opinion, in a web site, if a cache is not thread-safe, it almost useless, because the requests are not handled in ONE thread. Do you use Rails.cache in you webapp? And how do you use it?

    Besides modifying IIS to serve XAML extensions is there anything else that I need to do to allow IIS5 to server Silverlight pages? Do I actually need to run some Silverlight setup on the IIS5 web server or are all the setups intended for development machines and /or machines that end up consuming/browsing Silverlight pages?

  • jQuery UI datepicker performance

    - by Richard Ev
    I have a textbox on my web page that is used to specify a date, so I'd like to use the jQuery DatePicker. However, most of my users are locked into using IE6 and the performance of the jQuery DatePicker is a little sluggish in this browser. Can anyone recommend an alternate JavaScript date picker, or any means of improving the display performance of the jQuery DatePicker?

  • Clear cache with greasemonkey

    - by Paul
    I have a web application running in a kiosk, which is set up with greasemonkey so that we can customize little things about the application and ensure the customizations only occur at the kiosk. I have been digging through the GM api hoping that it would have some functionality to affect browser settings, but alas it looks like it only affects pages running in the browser. Is there a way for me to tell the browser to clear it's cache when a certain event happens in the application?

  • python Socket.IO client for sending broadcast messages to TornadIO2 server

    - by Alp
    I am building a realtime web application. I want to be able to send broadcast messages from the server-side implementation of my python application. Here is the setup: socketio.js on the client-side TornadIO2 server as Socket.IO server python on the server-side (Django framework) I can succesfully send socket.io messages from the client to the server. The server handles these and can send a response. In the following i will describe how i did that. Current Setup and Code First, we need to define a Connection which handles socket.io events: class BaseConnection(tornadio2.SocketConnection): def on_message(self, message): pass # will be run if client uses socket.emit('connect', username) @event def connect(self, username): # send answer to client which will be handled by socket.on('log', function) self.emit('log', 'hello ' + username) Starting the server is done by a Django management custom method: class Command(BaseCommand): args = '' help = 'Starts the TornadIO2 server for handling socket.io connections' def handle(self, *args, **kwargs): autoreload.main(self.run, args, kwargs) def run(self, *args, **kwargs): port = settings.SOCKETIO_PORT router = tornadio2.TornadioRouter(BaseConnection) application = tornado.web.Application( router.urls, socket_io_port = port ) print 'Starting socket.io server on port %s' % port server = SocketServer(application) Very well, the server runs now. Let's add the client code: <script type="text/javascript"> var sio = io.connect('localhost:9000'); sio.on('connect', function(data) { console.log('connected'); sio.emit('connect', '{{ user.username }}'); }); sio.on('log', function(data) { console.log("log: " + data); }); </script> Obviously, {{ user.username }} will be replaced by the username of the currently logged in user, in this example the username is "alp". Now, every time the page gets refreshed, the console output is: connected log: hello alp Therefore, invoking messages and sending responses works. But now comes the tricky part. Problems The response "hello alp" is sent only to the invoker of the socket.io message. I want to broadcast a message to all connected clients, so that they can be informed in realtime if a new user joins the party (for example in a chat application). So, here are my questions: How can i send a broadcast message to all connected clients? How can i send a broadcast message to multiple connected clients that are subscribed on a specific channel? How can i send a broadcast message anywhere in my python code (outside of the BaseConnection class)? Would this require some sort of Socket.IO client for python or is this builtin with TornadIO2? All these broadcasts should be done in a reliable way, so i guess websockets are the best choice. But i am open to all good solutions.
