  • How to prevent the user from leaving the page

    - by JohnathanKong
    Hey Everyone, I am currently building a registration site where if the user leaves, I want to pop up a CSS box asking him if he is sure or not. I can accomplish this feat using confirm boxes, but the client says that they are too ugly. I've tried using unload and beforeunload, but both cannot stop the page from being redirected. Using those to events, I return false, so maybe there's a way to cancel other than returning false? Another solution that I've had was redirecting them to another page that has my popup, but the problem with that is that if they do want to leave the page, and it wasn't a mistake, they lose the page they were originally trying to go to. If I was a user, that would irritate me. The last solution was real popup window. The only thing I don't like about that is that the main winow will have their destination page while the pop will have my page. In my opinion it looks disjoint. On top of that, I'd be worried about popup blockers.

  • Problem prompting user for extended permissions using showPermissionDialog in FB page tab

    - by snipe
    I have an FBML app that will use the tab as a promo tab before the full app goes live. The purpose of the promo tab is to allow users to opt in to email notifications (using the FB API sendNotifications call), so I need to prompt them to allow the app and grant extended permissions on that promo tab. The tab code is: <?php require_once 'config.php'; ?> <form id="form1"> <h1> <a href="#" clickrewriteform="form1" clickrewriteurl="http://www.mydomain.com/fanpageajax/result.php" clickrewriteid="allowapp">Step 1. Allow the Application</a> </h1> <div id="allowapp"></div> </form> <h1><a onclick="Facebook.showPermissionDialog('email');return false;"> Step 2. Grant extended permissions (intab)</a></h1> The result.php page just tags the API to ensure the allow prompt will show up. The problem is with the Step 2. Once the user has allowed the app, and they click on the Step 2, nothing happens. If they click on it twice, THEN the extended permissions dialog box popups up, but it asks them to grant extended permissions TWICE. OR.... If the user clicks on Step 1, and allows the app, and then reloads the fan page tab, they only have to click on the Step 2 link once, and the permissions show up. Anyone have any ideas? I have been beating myself in the head over this for hours.

  • Getting the full-name of the current user, returns an empty string (C#/C++)

    - by Nir
    I try to get the full-name of the current log-in user (Fullname, not username). The following code C#, C++ works fine but on XP computers not connected to the Net, I get empty string as result if I run it ~20 minutes after login (It runs OK whithin the first ~20 minutes after login) A Win32 API (GetUserNameEx) is used rather that PrincipalContext since it PrincipalContext may takes up to 15 seconds when working offline. Any Help why am I getting an empty string as result though a user full name is specified??? - C# Code public static string CurrentUserFullName { get { const int EXTENDED_NAME_FORMAT_NAME_DISPLAY = 3; StringBuilder userName = new StringBuilder(256); uint length = (uint) userName.Capacity; string ret; if (GetUserNameEx(EXTENDED_NAME_FORMAT_NAME_DISPLAY, userName, ref length)) { ret = userName.ToString(); } else { int errorCode = Marshal.GetLastWin32Error(); throw new Win32Exception("GetUserNameEx Failed.

  • jQuery recursive function to upload many files while giving the user some feedback

    - by checcco
    Hi guys, I'm trying to write a jQuery function to let users upload many files at once. Here's the function I thought to give the user some feedback about the upload process progress. function uploadFiles(numbersOfFiles, start) { $("#info").html(start + " files uploaded"); $.post('upload.php', { start: start }, function (data) { start += 5; if (start < numbersOfFiles) { $("#info").html(start + " files uploaded"); uploadFiles(numbersOfFiles, start); } else { $("#info").html("All files have been uploaded"); } }); } The function calls a php script to upload 5 files, then if there are more files to upload it calls the script again. The whole process works. I've tried it with 100 files. The only thing that doesn't work is the #info div updating. The div get updated the first time and then again only to show "All files have been uploaded". So there's no feedback for the user about the uploading process. I can't understand why... Any help?

  • Basic user authentication with records in AngularFire

    - by ajkochanowicz
    Having spent literally days trying the different, various recommended ways to do this, I've landed on what I think is the most simple and promising. Also thanks to the kind gents from this SO question: Get the index ID of an item in Firebase AngularFire Curent setup Users can log in with email and social networks, so when they create a record, it saves the userId as a sort of foreign key. Good so far. But I want to create a rule so twitter2934392 cannot read facebook63203497's records. Off to the security panel Match the IDs on the backend Unfortunately, the docs are inconsistent with the method from is firebase user id unique per provider (facebook, twitter, password) which suggest appending the social network to the ID. The docs expect you to create a different rule for each of the login method's ids. Why anyone using 1 login method would want to do that is beyond me. (From: https://www.firebase.com/docs/security/rule-expressions/auth.html) So I'll try to match the concatenated auth.provider with auth.id to the record in userId for the respective registry item. According to the API, this should be as easy as In my case using $registry instead of $user of course. { "rules": { ".read": true, ".write": true, "registry": { "$registry": { ".read": "$registry == auth.id" } } } } But that won't work, because (see the first image above), AngularFire sets each record under an index value. In the image above, it's 0. Here's where things get complicated. Also, I can't test anything in the simulator, as I cannot edit {some: 'json'} To even authenticate. The input box rejects any input. My best guess is the following. { "rules": { ".write": true, "registry": { "$registry": { ".read": "data.child('userId').val() == (auth.provider + auth.id)" } } } } Which both throws authentication errors and simultaneously grants full read access to all users. I'm losing my mind. What am I supposed to do here?

  • User submitted content filtering

    - by Jim
    Hey all, Does anyone have any ideas on what could be used as a way to filter untrustworthy user submitted content? Take Yelp for instance, they would need to prevent competitors writing business reviews on their competitors. They would need to prevent business owners favourably reviewing their own business, or forcing friends/family to do so. They would need to prevent poor quality reviews from affecting a businesses rating and so on. I can't think what they might use to do this: Prevent multiple users from the same IP reviewing certain things Prevent business owners reviewing their own business (maybe even other businesses in the same categories as their own?) Somehow determine what a review is about and what the actual intentions behind it are Other than the first and second points, I can't think of any clever/easy way to filter potentially harmful reviews from being made available, other than a human doing it. Obviously for a site the size of Yelp this wouldn't be feasible, so what parameters could they take into consideration? Even with human intervention, how would anyone know it was the owners best buddy writing a fake review without knowing the people? I'm using this as an example in a larger study on the subject of filtering user content automatically. Does anyone have any ideas how these systems may work and what they take into consideration? Thanks!

  • How to check user input for correct formatting

    - by Arcadian
    This is what i've come up with so far private void CheckFormatting() { StringReader objReaderf = new StringReader(txtInput.Text); List<String> formatTextList = new List<String>(); do { formatTextList.Add(objReaderf.ReadLine()); } while (objReaderf.Peek() != -1); objReaderf.Close(); for (int i = 0; i < formatTextList.Count; i++) { } } What it is designed to do is check that the user has entered their information in this format Gxx:xx:xx:xx JGxx where "x" can be any integer. As you can see the user inputs their data into a multi-line textbox. i then take that data and enter it into a list. the next part is where i'm stuck. i create a for loop to go through the list line by line, but i guess i will also need to go through each line character by character. How do i do this? or is there a faster way of doing it? thanks in advance

  • Asynchronously get user data in facebook tab?

    - by Kristoffer Nolgren
    Using the php sdk, I check if a user inside a tab likes the corresponding page. If i put the following code inside index.php and use that page as my page-tab-url, <?php require_once("facebook/facebook.php"); // Create our application instance // (replace this with your appId and secret). $facebook = new Facebook(array( 'appId' => '1399475990283166', 'secret' => 'mysercret', 'cookie' => true )); $signed_request = $facebook->getSignedRequest(); echo $signed_request['page']['liked']; ?> it outputs '1'. I would like to achieve this asynchronously instead, so I put the php in a separate file and try to access it using ajax instead $http.post('/facebook/likes.php'). success(function(data){ console.log(data); }).error(function(data){ console.log(data); } ); This sample is using angular, but what javascript library i'm using probably doesn't matter. When I access the info with javascript Facebook doesn't seem to get the info that I liked the page. Adding a print_r($facebook); on the page I'm retreiving the same values as if i'm not in a facebook-tab: ( [sharedSessionID:protected] => [appId:protected] => 1399475990283166 [appSecret:protected] => 679fb0ab947c2b98e818f9240bc793da [user:protected] => [signedRequest:protected] => [state:protected] => [accessToken:protected] => [fileUploadSupport:protected] => [trustForwarded:protected] => ) Can I access theese values asynchronosly somehow?

  • Checking if user owns file before deleting it

    - by Martin Hoe
    I'm building an API for my site that allows users to delete the files they upload. Obviously, I want to check if the user owns that file before they delete it through the API. I have a files table and a users table, here's the schema: f_id, s_id, u_id, name, size, uploaded u_id, username, password, email, activated, activation_code u_id is a foreign key. The u_id field in the files table points to the u_id in the users table. Given the users username, I want to find the users u_id, and then check if they own the file through the file ID (f_id). I wrote this SQL: $sql = 'SELECT u.username FROM `users` u JOIN `files` f ON u.u_id = f.u_id WHERE f_id = ? AND u.u_id = ? LIMIT 1'; I'm assuming that'd work if I was given the users u_id in the API request, but alas I'm given only their username. How can I modify that SQL to find their user ID and use that? Thanks. Edit: Alright I've got this query but it's always returning an empty result set even though both the file ID and username exist. SELECT u.username FROM `users` u JOIN `files` f ON u.u_id = f.u_id WHERE f.f_id = ? AND u.username = ? LIMIT 1

  • Ensuring WPF window is on top all the time even when user clicks another maximised application

    - by mttumbledown
    Hi I am trying to ensure my WPF window stays on top as long as it is open. It is acting as a pop-up set to TopMost=true, and a call to the win32 SetWindowPos to TOPMOST. When first opened it appears on top of another running application on the desktop- maximized or not. If the user activates or uses a window in the application mine loses focus and disappears. I thought of manipulating the other application window, setting it to a lower z index. How do I find the application window? How do I iterate through all windows? (This question still stands, even if it is not the correct approach). I would be using SetWindowPos, GetForegroundWindow, GetForegroundWindow, GetDesktopWindow et cetera. I suspect that as soon as the user clicks in their application that it will still focus it regardless and I am barking up the wrong tree. At the moment, my application is a black box and I can’t handle it the other way, for example, periodically messaging my app to focus. I also thought of having a long running background thread which periodically focuses my WPF popup, but need to watch resources and processor. Kind regards,

  • Multi-user job/task tracking/queue software

    - by Bmsgaffer86
    Background: I test and repair electronic products with a team. There are many 'jobs' going through my lab at any point in time. It is getting difficult to track whats coming in and going out because I don't do every test or repair myself. Target: User can enter a job when they drop it off in my lab, and it will appear on the master list or queue. Needs to have priorities and due dates that can be adjusted by users. Ideally this would be web based and open-source, but I am flexible. Dream: A large monitor displaying a list of jobs in the master queue with details. This is very optional though, and would be in the best case scenario. I have done MANY hours of Google-ing and I am not sure if I have been using the right terminology, but I have not found anything that is simple enough to stand alone yet complex enough to be multi-user based. I am mildly proficient in VB, and have the drive to piece anything together that I have to. I am open to ANY help or suggestions.

  • create php form, show message depending user choice

    I want to create a php form with checkbox, like this: < form method="post> <input type="checkbox" name="formpractise[]" value="A" /> <br/> <br/> <input type="checkbox" name="formpractise[]" value="B" /> <br/> <br/> <input type="checkbox" name="formpractise[]" value="C" /> <br/> <br/> <input type="checkbox" name="formpractise[]" value="D" /> <br/> <br/> <input type="checkbox" name="formpractise[]" value="E" /> <br/> <br/> <input type="checkbox" name="formpractise[]" value="F" /> <br/> <br/> <input type="submit" name="formsubmit" value="Submit" /> </form> When the user select checkbox I want to print a message according user choice. Not the choice he made, a message depending his choice.

  • storing user input into string array in C

    - by Jcmoney1010
    I'm writing a program that is supposed to take in a list of names from the user, store them in an array, and then search through the list to check and see if the next name the user enters is part of the original list of names. The issue I'm having is that when I go to enter a list of names, it only saves the last name entered into the list. I've searched the web and this site for similar issues, but I can't seem to find anything that answers this issue specifically. Here is the part of code where I have problem void initialize(char names[][],const int MAX_NAMES,const int MAX_NAMELENGTH) { int i,Number_entrys; printf("How many names would you like to enter to the list?"); scanf("%d",&Number_entrys); if(Number_entrys>MAX_NAMES){ printf("Please choose a smaller entry"); }else{ for (i=0; i<Number_entrys;i++){ scanf("%s",names); } } printf("%s",names); } trying very hard to teach myself, so be gentle lol.

  • C# HttpWebResponse Error 502 Bad Gateway

    So i'm using this class to POST on a webpage. The server i'm trying to POST to gives me a 502 Bad Gateway error. I think it has something to do with the user agent. I've already added my firefox user agent to the request but it seems to lose it on the response. I've tried using google and found some other articles on this like this one: Error 502 (Bad Gateway) when sending a request with HttpWebRequest over SSL but I don't know how to fix it since im not that good at c#.

  • Mercurial Tagging/Branching Strategy

    - by Tony Trozzo
    My current project is broken down into 3 parts: Website, Desktop Client, and a Plug-in for a third party program. We had started out originally with Subversion for our source control but decided to try Mercurial after reading Joel Spolsky's final post. Considering we haven't really used the majority of svn's potential before, we figured starting fresh with some basic ideas of how source control worked would make this transition easy. However, after setting up our initial repository, we're lost as to how tagging and branching should work on a project like this. Essentially, we're working on all 3 of these parts at the same time. We want a release to be a combination of the 3 parts. Currently we're working in one repository. For the Plug-in part, we have the first iteration finished which we've been referring to as Plug-In v0.1. For the first official build of the other two parts, we'd also like to refer to them as Website v0.1 and Desktop Client v0.1. When all three parts are at v0.1, we'd like to have a Full Project v0.1. Our problem is we're not sure how to manage all of this in the Hg repository. Would the best way to handle this be to create 3 separate repositories for the 3 stable versions and then 3 more repositories for the current developments? Currently we have this all in one repository. Should we do this in branches (are branches any different from cloning repositories?) and tags? Any help is greatly appreciated.

  • Recommendations on SharePoint site permission model

    - by Sachin
    Hi All, I have a SharePoint site which contains a root site and site collection in it. Now there are some sites that inherits permissions from their parent site and some site has their own permission module. Now a user from owner group of root site browses site collection but there are few site which doesn't allow user to view the content of it. Now what I want is general recommendation on when creating a new site in SharePoint what is best possible approach to set site permission. In what case we can inherits permissions from parent site..? In what case we can we us unique permission for a site..? If a site has unique permission set then is it possible to creat a group at root level which has access to all site collection irrespective of site permission model? I want a general recommendation based on above scenario. Any help will be appriciable. Thanks Sachin

  • Using Git with shared (symbolic link) directories

    - by chmike
    I'm working on a big Qt application with multiple widgets which are quite complex. One of this widget is a webcam stream viewer. The application is organized so that each program module (i.e. widgets) is stored in its own directory with a .pri file. All these are stored in one main directory grouping all the widget directories. Next to this main project directory I also have application directories. Let say one for each widget. In these directory I have a symbolic link (alias on windows) to the module directory in the main project folder. This application has then the necessary code to build a standalone application showing only the widget. So for instance I have a webcam viewer application, another to control some devices, etc. This source code organization works well and allows me to develop and test the widgets in independent applications while sharing the code with the main application. Currently only the main project directory is under version control using subversion. Now I would like to start using git and would like to know if this shared directory model would work with it or if there is a better way to do it.

  • How can I differentiate between the .net WebBrowser component and an actual browser?

    - by Septih
    OK, so we have an online downloads store accessed via our software. Recently we've had requests to allow downloads via normal browsers and it's fairly easy just to slap a download page on. The problem is that it would be confusing to people having two download links, one for the software and one for their web browser, so we want to differentiate between the two and only show the relevant download link. From what I've gathered, the .net WebBrowser component is the same as IE and uses the same User Agent, so we can't use that unless we subclass the WebBrowser in the software to make it use a specific User Agent. It's the more sensible option, but we'd have to roll out another updated version, which is less than ideal. Are there any other ways to tell if someone's accessing a site via the .net component? My only other alternative is to copy the store to a different address with the different download links and send people there. Again this is doable, but not ideal.

  • Has anyone used Rational Team Concert (RTC)?

    - by FryGuy
    The company I work for is currently evaluating replacements for SourceSafe, and for various reasons, I think RTC will be chosen. I'm a little scared that we're going to end up with a solution that isn't the best for us in our situation. I've tried researching a little bit about what it is, but all I have been able to find are marketing things, but nothing about how it actually works (any of the paradigms it uses, etc). Our team is around 8 developers and 2 QA people on a single project (and 4-5 more people that would be using it for their independent project). It seems like RTC is targetted for larger teams, but our team is relatively small. Does anyone has experience using RTC in a smaller team? The project that would be using it is a .NET/WPF application, so we would be using primarily Visual Studio. Is the Visual Studio integration any good, or are we stuck having to have Eclipse open on top of Visual Studio? Personally, I have been using Bazaar as my personal source control (and checking out/into sourcesafe from a branch), as well as on personal projects. Does RTC incorporate features of "third generation" version control systems, such as first class branching/merging and changesets rather than file changes, and good visualization of where changes come from? Also, what are the general pros and cons for it?

  • Bazaar + CruiseControl.Net

    - by Chris Gill
    I want to setup CruiseControl.Net at my company. We currently have several .net solutions stored in a Bazaar repository and I want to use MSBuild to build each solution. This didn't seem too controversial, but I can't see an easy way of binding CruiseControl.Net to Bazaar. There seems to have been a plugin to do this at http://www.sorn.net/projects/bazaar-ccnet but this link no longer works and I cant seem to find the plugin anywhere else I was going to use the External source control type, but bazaar seems to bork at the GETMODS parameter being passed to it My current thought now is to create a separate project to pull modifications from bazaar using an Exec task, then create another project to run a FileSystem source control check on that directory. I'm moderately sure I can get this to work, but it seems a bit hacky. I don't mind writing a new Bazaar plugin for CruiseControl.Net but I cant find where to start with this. My questions are do you run these two in combination, if so how do you do it? If you don't run these together, do you have any recommendations on a good approach? Is there any documentation or good starting point that I could use to write a bazaar plugin? Am I an idiot for trying to use CruiseControl.Net? Should I be using something else?

  • Know any unobstrusive, simple GUI guidelines or design recommendations for notifications?

    - by Vinko Vrsalovic
    Hello again. I'm in the process of designing and testing various ideas for an application whose main functionality will be to notify users of occurring events and offer them with a choice of actions for each. The standard choice would be to create a queue of events showing a popup in the taskbar with the events and actions, but I want this tool to be the less intrusive and disrupting as possible. What I'm after is a good book or papers on studies of how to maximize user productivity in these intrinsically disruptive scenarios (in other words, how to achieve the perfect degree of annoying-ness, not too much, not too little). The user is supposedly interested in these events, they subscribe to them and can choose the actions to perform on each. I prefer books and papers, but the usual StackOverflow wisdom is appreciated as well. I'm after things like: Don't use popups, use instead X Show popups at most 3 seconds Show them in the left corner Use color X because it improves readability and disrupts less That is, cognitive aspects of GUI design that would help users in such a scenario.

  • Resources for Programmatic Rendering of Topology Maps

    - by bn
    Servus, Do you know of any frameworks, APIS, languages, or other resources that are well suited for drawing topology maps that allow a user to interact with objects on the map? I am not constrained by language choice and the program can be web-based, or stand-alone. I thought I would check before rolling my own. My goal is not to draw cartographic maps, but more like this picture: http://www.fineconnection.com/files/images/GraphicalNM.PNG, or if you are familiar with Edward Tufte's books, the data-visualization mechanisms he describes such as a map of a metro or subway. Also, if you have had any experience rendering these types of user interfaces or usage of underlying datastructures, I would be grateful to hear any thoughts you have on the subject, advice, any "gotchas." Thank you very for your time, -bn

    I'm working on a side project to build a new web app idea of mine. For the sake of discussion, let's say this app displays a random photograph of a famous work of art. On a scale of 1 to 5, users are asked to rate how well they like each piece of art, and then are shown the next photo. Eventually, the app is able to get an sense of the person's style and is able to recommend artwork that he/she may find pleasing. The whole concept is similar to Netflix. I understand how to do all the preference matching logic (although not as sophisticated as Netflix). But I'd like to find a way to do this without requiring that users create an account first. This is a novelty website that a typical user might use only a handful of times. Requiring registration is overkill and will likely drastically reduce it's utility. I'd like to allow people to begin rating artwork within five seconds of their initial pageview, yet maintain the integrity of the voting (since recommendations are predicated on how other people have rated the various pieces of artwork). Can it be done? Some ideas: OpenID. The perfect solution except for the fact that it's not wildly used and my target audience isn't the most technically adept demographic. Text message. User inputs phone number and is texted a four digit code to key into the web app. Quick, easy, and great way to limit abuse. However, privacy concerns abound... people are probably even less likely to give me their phone number than their email address. Facebook login. I personally don't have a Facebook account due to privacy concerns. And I'd really hate to support such a proprietary platform. Hash code/Bookmark. Vistor's initial pageview generates a 5 or 6 digit alphanumeric code that is embedded in each subsequent URL. They can bookmark any page to save their state. Good: Very simple system that doesn't require any user action. Bad: Very easy to stuff the ballot box, might be difficult to account for users sharing the link containing their ID code via email or social networking sites.
