• Strange client's address returned throug accept(..) function.

  - by Negai

  Hi everyone, I'm a socket programming newbie. Here's a snippet: struct sockaddr_storage client_addr; ... client_addr_size = sizeof(client_addr); client_socket = accept( server_socket, (struct sockaddr *)&client_addr, &client_addr_size ); ... result = inet_ntop( AF_INET, &((struct sockaddr_in *)&client_addr)->sin_addr, client_addr_str, sizeof(client_addr_str) ); Whenever the client connects the address I get is 0.0.0.0 regardless from the host. Can anybody explain, what I'm doing wrong? Thanks.

• How can I upload a file to a Sharepoint Document Library using Silverlight and client web-services?

  - by pclem12

  Most of the solutions I've come across for Sharepoint doc library uploads use the HTTP "PUT" method, but I'm having trouble finding a way to do this in Silverlight because it has restrictions on the HTTP Methods. I visited this http://msdn.microsoft.com/en-us/library/dd920295(VS.95).aspx to see how to allow PUT in my code, but I can't find how that helps you use an HTTP "PUT". I am using client web-services, so that limits some of the Sharepoint functions available. That leaves me with these questions: Can I do an http PUT in Silverlight? If I can't or there is another better way to upload a file, what is it? Thanks

• Should XML be used server-side, and JSON client-side?

  - by Michel Carroll

  As a personal project, I'm making an AJAX chatroom application using XML as a server-side storage, and JSON for client-side processing. Here's how it works: AJAX Request gets sent to PHP using GET (chat messages/logins/logouts) PHP fetches/modifies the XML file on the server PHP encodes the XML into JSON, and sends back JSON response Javascript handles JSON information (chat messages/logins/logouts) I want to eventually make this a larger-scale chatroom application. Therefore, I want to make sure it's fast and efficient. Was this a bad design choice? In this case, is switching between XML and JSON ok, or is there a better way?

• Which svn client to install on Windows 7 machine?

  - by user246114

  I just got a new PC running Windows 7 (64-bit). I'd like to install an SVN client (command line only, I don't want TortoiseSVN). I'm not sure which of these to install: http://subversion.apache.org/packages.html#windows does anyone have any opinions on this? I tried going for the ones hosted by Tigris, but the downloaded zip says to read an install file hosted at their site, but the link is broken. Do we simply download, then call svn.exe as needed, no need for a real 'install'?

• How to do client callback for each item in a foreach statement using c#?

  - by Mike108

  I want to show each item Id that is doing now dynamically in a foreach statement. How to do some kind of client callback to show the item Id in a foreach statement? <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label> <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" /> . protected void Button1_Click(object sender, EventArgs e) { List<int> list = new List<int>() { 1,2,3,4,5 }; foreach (var item in list) { Label1.Text = string.Format("I'm doing item {0} now.", item.ToString()); Page.RegisterStartupScript("", string.Format("<script>alert('doing item {0} now')</script>", item.ToString())); Thread.Sleep(1 * 1000); } }

• Online webcam chat. Free server and easy-to-implement client?

  - by Oskar Kjellin

  I have a client requesting that his users can use their webcams to talk to each other. From what I've understood the main thing to use for this is Flash. However as I have not written flash I would like to have something really easy to implement. Of course preferrably free (or trial). The idea of this is that everything but the chat alone is in .net. So the users will not use flash until they are actaully going to talk to each other. So there is no use for rooms here. I've been looking into silverlight some as well. But it seems like silverlight does not offer streaming between users..? I know this question has been asked many times here. But I could not find a suitable answer which is why I post a new question.

• Can a Client Link to My JavaScript, Hosted on a Different Domain?

  - by DaveDev

  Is it possible for me to supply a client with a snippet of HTML which contains a reference to a javascript file that I host? They want to paste this HTML into their CMS, so that when their page loads, it'll load our content. I was under the impression that there was cross domain security preventing this from being possible. What if, instead of linking to the JavaScript, I gave them the snippet of HTML with the JavaScript already included so instead of <div> <!-- link to js --> </div> I gave them <div> $.get(/*url to my content*/); </div> Would that work?

• How can I push a string from one client connected to a WCF service to another connected as well?

  - by Sergio Tapia

  Here's what I have so far: IService: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.ServiceModel; namespace ServiceLibrary { [ServiceContract(SessionMode = SessionMode.Allowed, CallbackContract = typeof(IServiceCallback))] public interface IService { [OperationContract(IsOneWay = false, IsInitiating = true, IsTerminating = false)] void Join(string userName); } interface IServiceCallback { [OperationContract(IsOneWay = true)] void UserJoined(string senderName); } } Service: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.ServiceModel; namespace ServiceLibrary { [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession, ConcurrencyMode = ConcurrencyMode.Multiple)] public class Service:IService { IServiceCallback callback = null; public void Join(string userName) { callback = OperationContext.Current.GetCallbackChannel<IServiceCallback>(); } } } Just a simple string passed from one client to another.

• How do I implement SAML 2.0 in a WCF Client?

  - by Tone

  I need to implement SAML 2.0 for a WCF client that is talking to a java web service (Glassfish). I know very little about SAML, and after a bit of searching here (and elsewhere) I do not find much about how to implement with WCF. Since WCF abstracts you away from the SOAP layer how can I add SAML assertions to the SOAP header? Will a 3rd party tool like ComponentSpace work best? Or should I roll my own? Other advice?

• Is is possible to parse a web page from the client side for a large number of words and if so, how?

  - by Technoh

  I have a list of keywords, about 25,000 of them. I would like people who add a certain < script tag on their web page to have these keywords transformed into links. What would be the best way to go and achieve this? I have tried the simple javascript approach (an array with lots of elements and regexping/replacing each) and it obviously slows down the browser. I could always process the content server-side if there was a way, from the client, to send the page's content to a cross-domain server script (I'm partial to PHP but it could be anything) but I don't know of any way to do this. Any other working solution is also welcome.

• Pass HTML form entries into a Javascript array to then be written to a client side cookie?

  - by Tom

  I'm building a bit of a test-case JS application, something very basic, but have run into some problems. I'm trying to use a HTML form for a user to enter a number, which is then written to a Javascript Array. The user then has the option to write that same array to a local (client side) cookie. (I understand the security implications of this - it's a test-case and not for commercial use.) However, I can't make the connection - how can I capture the HTML entry, press 'submit' which will send it to a JS array, where the user can then press a different 'submit' which will write the array to a text file? If anyone can help I'd appreciate it because it's been nearly 6 hours and it's not funny anymore.

• How to handle User Authentication for program in client’s local machine?

  - by Daniel

  Which user authentication scheme could be used at following scenario? 1.Application A developed by my company is installed at user's local computer. 2.Users login at my company's website. 3.If login is successful, access to the application A in user's local machine is granted. The development environment is .NET. Is there a secure way to authenticate the user to access the application? I've thought about encrypting the login information entered at the website, and then sending that information to the program at user's local machine for authentication. but I think as long as the client program has the decrypting ability, it is vulnerabe to decompiling,etc. Thanks in advance!

• What should I ask a prospective client during initial meeting?

  - by Anna Lear

  I'm about to branch out into taking on some contracts on the side. What would be some good questions to ask of a potential client during a first meeting? I've thought of a few things that seem pretty obvious: * What is the project? * What are the deadlines? * What's the budget? * What/how do they want me to deliver the completed work? Is that it, or are there any tricky things to watch out for?

• When we run an aspx page with client side scripting on IIS, we get an ActiveX control error?

  - by Ananya

  we have implemented the code for installing the messenger theme pack using the client side scripting in a web page. We are creating an object of the messenger using the classid .Using this object we call the installcontent() method and try to install the messenger theme pack hosted at following path: http://www.messengerexpressions.com/assets/worldCup/cabs/en-gb.cab Our code initially checks whether the messenger is installed on the user machine or not. Then it checks for the user login ,once the messenger is installed on the machine. And if the user is signed-in , the messenger theme pack is installed. The code currently when hosted on IIS checks the “Sign-In of the user” but when it tries to install the theme pack an error is thrown “An ActiveX control on this page is unsafe.Your current security settings prohibit running unsafe control on this page.As a result,this page may not be display as intended.” Please let us know if any setting is required on IIS for running this piece of codeor anything that we are missing out.

• Should I move client to Lamp or develop on Wamp?

  - by John Isaacks

  I have never developed for WAMP, the hosting guy for my new client says they are using Windows servers, they can setup PHP and MySQL for me, but they cannot switch to a *nix server. He said there are some nuances from PHP on *nix Vs. win. So my question is, if I have never programmed PHP on win, should I go through the hassle of switching hosts (since they cannot do *nix themselves), or are the differences slight enough that it shouldn't be too big a problem for me? (side note: the state of the clients website has no effect since it is a static all-flash site and is going to be completely rebuilt) Thanks!

• How do I get User.message_set messages to show up for the built in test client?

  - by Conley Owens

  I'm aware that the old Django messages framework is deprecated, but I still would like to know the answer to this. When I go to a certain url to my broswer, a message is created, I am redirected to a different page, and I see the message correctly displayed by my template. When the test client goes to the same url, the message is created, it gets a redirect, and after following the redirect there are no messages. However, no messages appear in the response (the response gotten from following the redirect). Why not?

• Facebook Error: "The client token cannot be used for this API" - works on DEV and STAGE but not on LIVE app?

  - by Studio Temp

  I've built a notification sending system that sends notifications to all users of our app, using the app access token. This system is currently running on my localhost. When I configure it with the appid and appsecret for my dev and stage environments, it works fine. But when I put in the appid and appsecret of the LIVE app, I get this error: {"message":"The client token cannot be used for this API", "type":"OAuthException", "code":190} So what's different between dev and live? Dev and Stage are in sandbox mode, Live is not. So I tried disabling sandbox mode on Dev/Stage and they continue to function fine. Dev works fine, Stage works fine, Live gives this error. All other code is the same except for the appid, appsecret, and redirect_uri (changing it to match the domain of each environment). I have checked this post, but unfortunately resetting our appsecret on a site with 1,000,000 users is not something we can do at the moment (too much other functionality relies on it).

• Is there any way to view PHP code (the actual code not the compiled result) from a client machine?

  - by Columbo

  This may be a really stupid question...I started worrying last night that there might be someway to view PHP files on a server via a browser or someother means on a client machine. My worry is, I have an include file that contains the database username and password. If there were a way to put the address of this file in to a browser or some other system and see the code itself then it would be an issue for obvious reasons. Is this a legitimate concern? If so how do people go about preventing this?

• Where happens merging in SVN - on the client or server?

  - by Malcolm Frexner

  At my company we evaluate working with feature branches. We want to use mergeinfo to track merging. I have issues in some of our tested projects where merging a trunk that has only little changes into branch leads to lots of changed files because of the changed mergeinfo. I read that this behaviour improoved between version 1.5 and 1.6. Does this mean if I update the SVN - server from 1.5.6 to 1.6 I can expext some improvements when merging, or does this depend on the client (which is 1.6.11)?

• Upload file from client machine to server - prepopulate file picker path?

  - by user246114

  Hi, I'd like to upload a file from a client machine to my server. The user would have to specify the file to upload as I understand it, using a form that looks like: <input type="file" name="datafile" size="40"> This pops up a native file picker, which is great. The problem I'm having is that it's a real pain (for most users) to go looking around their machine for the file I'm interested in. Is there a way I can initialize the file picker with a path to make it more convenient for the user? Like I know some users will be on a windows machine, so I could prepopulate the picker by already sending them to the My Documents folder for example. I don't see how this is possible, just wondering if something like that exists, Thank you
