  • How to deal with social login

    - by Matteo Pagliazzi
    In my new web app I'm going to allow social login through Twitter (maybe), Facebook and Google and I'm in search of the best way to do it. Actually I'm using Rails with Devise + Omniauth and this is the problem: Should I ask the user to choose a password so that he can login without a social network? Or maybe the user should be able to set a password if he want (for example when editing his account?) The second way seems the best one but since Twitter doesn't provide user email and google doesn't provide an username I'll probably have to ask the user for username/email when he log in so in that case I may also ask for the password... waht do you think?

  • Windows 7 Utlimate x64 - No Internet access

    - by rafek
    I've just installed Windows 7 Ultimate x64. As all of my computers at home I've connected to my router via wifi (open/wep). And what has happened is that Wireless Connection is Connected but with No Internet access -- my ipconfig says: Autoconfiguration IPv4 Address : 169.254.33.161 Subnet Mask : 255.255.0.0 Default Gatewawy : (empty) After ipconfig /renew I get: An error occurred while renewing interface Wireless Network Connection : unable to contact your DHCP server. Request has timed out. [..] I'm looking for a solution for 2 hours now...

  • In what way does non-"full n-key rollover" hinder fast typists?

    - by Michael Kjörling
    Wikipedia claims (although the latter claim does not cite a source) that: High-end keyboards that provide full n-key rollover typically do so via a PS/2 interface as the USB mode most often used by operating systems has a maximum of only six keys plus modifiers that can be pressed at the same time.[4] This hinders fast typists, ... In what way would the system being able to recognize only six non-modifier keys at once hinder a fast typist? I consider myself a relatively fast typist and I usually press one key, plus modifiers, at once; I can't imagine any real-life situation in which the system only recognizing six non-modifier keys being pressed at once has been a limiting factor in my keyboard usage. (Multi-stroke keyboard shortcuts as used by high-end software like Visual Studio, Emacs and the like are a different matter.) Note that I am not really interested in answers centered around multiplayer computer games; I'm looking for answers that give reasons that would be relevant to typists, somehow supporting the statement made on Wikipedia.

  • Cancelling Route Navigation in AngularJS Controllers

    - by dwahlin
    If you’re new to AngularJS check out my AngularJS in 60-ish Minutes video tutorial or download the free eBook. Also check out The AngularJS Magazine for up-to-date information on using AngularJS to build Single Page Applications (SPAs). Routing provides a nice way to associate views with controllers in AngularJS using a minimal amount of code. While a user is normally able to navigate directly to a specific route, there may be times when a user triggers a route change before they’ve finalized an important action such as saving data. In these types of situations you may want to cancel the route navigation and ask the user if they’d like to finish what they were doing so that their data isn’t lost. In this post I’ll talk about a technique that can be used to accomplish this type of routing task.   The $locationChangeStart Event When route navigation occurs in an AngularJS application a few events are raised. One is named $locationChangeStart and the other is named $routeChangeStart (there are other events as well). At the current time (version 1.2) the $routeChangeStart doesn’t provide a way to cancel route navigation, however, the $locationChangeStart event can be used to cancel navigation. If you dig into the AngularJS core script you’ll find the following code that shows how the $locationChangeStart event is raised as the $browser object’s onUrlChange() function is invoked:   $browser.onUrlChange(function (newUrl) { if ($location.absUrl() != newUrl) { if ($rootScope.$broadcast('$locationChangeStart', newUrl, $location.absUrl()).defaultPrevented) { $browser.url($location.absUrl()); return; } $rootScope.$evalAsync(function () { var oldUrl = $location.absUrl(); $location.$$parse(newUrl); afterLocationChange(oldUrl); }); if (!$rootScope.$$phase) $rootScope.$digest(); } }); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The key part of the code is the call to $broadcast. This call broadcasts the $locationChangeStart event to all child scopes so that they can be notified before a location change is made. To handle the $locationChangeStart event you can use the $rootScope.on() function. For this example I’ve added a call to $on() into a function that is called immediately after the controller is invoked:   function init() { //initialize data here.. //Make sure they're warned if they made a change but didn't save it //Call to $on returns a "deregistration" function that can be called to //remove the listener (see routeChange() for an example of using it) onRouteChangeOff = $rootScope.$on('$locationChangeStart', routeChange); } This code listens for the $locationChangeStart event and calls routeChange() when it occurs. The value returned from calling $on is a “deregistration” function that can be called to detach from the event. In this case the deregistration function is named onRouteChangeOff (it’s accessible throughout the controller). You’ll see how the onRouteChangeOff function is used in just a moment.   Cancelling Route Navigation The routeChange() callback triggered by the $locationChangeStart event displays a modal dialog similar to the following to prompt the user:     Here’s the code for routeChange(): function routeChange(event, newUrl) { //Navigate to newUrl if the form isn't dirty if (!$scope.editForm.$dirty) return; var modalOptions = { closeButtonText: 'Cancel', actionButtonText: 'Ignore Changes', headerText: 'Unsaved Changes', bodyText: 'You have unsaved changes. Leave the page?' }; modalService.showModal({}, modalOptions).then(function (result) { if (result === 'ok') { onRouteChangeOff(); //Stop listening for location changes $location.path(newUrl); //Go to page they're interested in } }); //prevent navigation by default since we'll handle it //once the user selects a dialog option event.preventDefault(); return; } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Looking at the parameters of routeChange() you can see that it accepts an event object and the new route that the user is trying to navigate to. The event object is used to prevent navigation since we need to prompt the user before leaving the current view. Notice the call to event.preventDefault() at the end of the function. The modal dialog is shown by calling modalService.showModal() (see my previous post for more information about the custom modalService that acts as a wrapper around Angular UI Bootstrap’s $modal service). If the user selects “Ignore Changes” then their changes will be discarded and the application will navigate to the route they intended to go to originally. This is done by first detaching from the $locationChangeStart event by calling onRouteChangeOff() (recall that this is the function returned from the call to $on()) so that we don’t get stuck in a never ending cycle where the dialog continues to display when they click the “Ignore Changes” button. A call is then made to $location.path(newUrl) to handle navigating to the target view. If the user cancels the operation they’ll stay on the current view. Conclusion The key to canceling routes is understanding how to work with the $locationChangeStart event and cancelling it so that route navigation doesn’t occur. I’m hoping that in the future the same type of task can be done using the $routeChangeStart event but for now this code gets the job done. You can see this code in action in the Customer Manager application available on Github (specifically the customerEdit view). Learn more about the application here.

  • D-Link DNS-323 NAS firmware update

    - by Mark Beaton
    Hi all, I've got a D-Link DNS-323 NAS enclosure holding a bunch of multimedia files that I've (possibly stupidly) just updated the firmware on, from 1.03 to 1.08. The updater indicated it applied the firmware patch successfully, but after rebooting it I can no longer get into it via the web interface, either via the static IP I had assigned it before the update, or by any of the DHCP-assigned addresses that I can see are currently assigned by my router. The unit just sits there, with the drives (2x512 set up as RAID-1) thrashing away seemingly forever... So, my question - has anyone had a similar experience with one of these units? Any advice etc? I've googled the hell out of it, and can't find anything useful.

  • Plesk hosting on MediaTemple DV

    - by David
    Hi there, We have a MediaTemple dedicated virtual running Plesk. The problem we're having is that changing the permissions of files on the server to be writable by server owner (apache) is conflicting with the ability to upload and overwrite files via the FTP user. Here's an example, I upload a file from user "serverftp" and they own the new file in the httpdocs folder. I then change the permission of an image upload folder to the apache user to that I can upload images via a PHP script. Uploading or changing that folder with the serverftp user is then locked out. Speaking to tech support didn't get very far because there are some strange group permissions going on and it would involve me adding every single domain FTP user to the pcantl group or something similar. I'm wondering how I can easily change things so that I don't have this problem anymore.

  • setting nproc in /etc/security/limit.conf prevents ssh login

    - by omry
    I am trying to use /etc/security/limit.conf on Linux (Debian) to limit the number of processes per user. for starters, I tried to limit my own user processes by adding this to /etc/security/limit.conf: omry hard nproc 100 this locked my user out of ssh. I could open new processes (verified with su omry), but could not log into ssh with that user : sshd reported this in it's log: fatal: setreuid 1000: Resource temporarily unavailable also, I am certain my user is not running anything near 100 processes (actually 6). what can be the reason for this?

  • How to set up wireless access on a Cisco router

    - by Carlos
    Hi, I've set up my 877W according to the configuration listed in this forum post: IPTV over Cisco 877 (It's the working configuration at the bottom of the post) Note that I have an 877W, so it also has a wireless radio. Now, I've gotten the whole setup to work, so IPTV is working, and I can access the internet via the ethernet ports. Now I'm trying to figure out how to allow access via the dot11radio interface. I've gathered that I basically need to create a bridge group, and bridge the radio to the internet VLAN. However, when I add a bridge-group 2 command to VLAN1, it seems to take down the whole internet VLAN. (The IPTV continues to work.) This makes the router itself inaccessible (I've got a laptop, so no serial) and I end up having to reboot the router. Can anyone tell me how to a) Allow wireless access to the internet (preferably with WEP, to match my old router) b) Determine what makes the router inaccessible when I add the new bridge group c) Forward the IPTV traffic onto a machine on my internet VLAN

  • Application Module Extension in Oracle Application R12

    - by Manoj Madhusoodanan
    In this blog I will describe how to Extend Application Module.I will explain this based on my previous blog PL/SQL based EO.  I want to extend FndUserAM to add a procedure to raise a custom business event when the FND_USER has created successfully. Here I am using a custom business event "xxcust.oracle.apps.demo_event". Please find the code used in Business Event. TablePackage Following steps needs to perform. 1) Download all files pertaining to "Entity Object Based on PL/SQL" to JDEV_USER_HOME/myprojects and JDEV_USER_HOME/myclasses.If you want to see the content of source java file decompile it and save it in JDEV_USER_HOME/myprojects. 2) Create XXFndUserAM as follows. 3) Add following method to XXFndUserAMImpl.    import oracle.apps.fnd.framework.OAException;   import oracle.apps.fnd.framework.server.OADBTransactionImpl;   import oracle.apps.fnd.wf.bes.BusinessEvent;   import oracle.apps.fnd.wf.bes.BusinessEventException;    import java.sql.Connection;     public void raiseEvent(String userName) {        String eventName = "xxcust.oracle.apps.demo_event";        String eventKey = userName;        Connection conn = ((OADBTransactionImpl)getOADBTransaction()).getJdbcConnection();         BusinessEvent event = null;         try{             event = new BusinessEvent(eventName, eventKey);             /* Setting Parameters */             event.setStringProperty("USER_NAME",userName);             event.setStringProperty("STATUS","User has created sucessfully");             event.raise(conn);             }             catch (BusinessEventException e) {                 throw new OAException("Exception occured when invoking web service - "+e.getMessage());             }             getOADBTransaction().commit();    } 4) Create a controller which extends from xxcust.oracle.apps.fnd.user.webui.CreateFndUserCO.Call raiseEvent method from new controller. 5) Create substitution for FndUserAM. 6) Migrate following files to $JAVA_TOP. xxcustom.oracle.apps.fnd.user.server.FndUserAMImpl.javaxxcustom.oracle.apps.fnd.user.server.XXFndUserAM.xmlxxcustom.oracle.apps.fnd.user.webui.XXCreateFndUserCO.java 8) Migrate the substitution. 9) Restart the server. 10) Personalize the page /xxcust/oracle/apps/fnd/user/webuiCreateFndUserPG and set the new controller. 11) Verify the substitution has properly applied by clicking About the Page. 12) Access the page and create a user. You can the the result of the Business Event.

  • WLAN LED randomly blinking when there is no traffic

    - by mrc
    Hi, I've got a Linksys WUSB54GC WLAN USB interface (Ralink chipset) and I'm running Debian GNU/Linux 6.0. The LED very often randomly blinks although there is no traffic in the network. I checked this with Wireshark. Sometimes, but rarely, the LED stops blinking. The issue is present in Ubuntu and Fedora too. It was not present in Debian Lenny with Linux 2.6.28. I checked an old live cd with ubuntu 8.10 with kernel 2.6.27 and it was also OK. So I guess that's an issue with Linux kernel and its wireless driver or firmware. Has anybody observed a similar thing? Does anybody know how to help this annoying blinking? Thanks.

  • Mobile App Notifications in the Enterprise Space: UX Considerations

    - by ultan o'broin
    Here is a really super website of UX patterns for Android: Android Patterns. I was particularly interested in the event-driven notification patterns (aka status bar notifications to developers). Android - unlike iOS (i.e., the iPhone) - offers a superior centralized notifications system for users.   (Figure copyright Android Patterns)   Research in the enterprise applications space shows how users on-the-go, prefer this approach, as: Users can manage their notification alerts centrally, across all media, apps and for device activity, and decide the order in which to deal with them, and when. Notifications, unlike messages in a dialog or information message in the UI, do not block a task flow (and we need to keep task completion to under three minutes). See the Anti-Patterns slideshare presentation on this blocking point too. These notifications must never interrupt a task flow by launching an activity from the background. Instead, the user can launch an activity from the notification. What users do need is the ability to filter this centralized approach, and to personalize the experience of which notifications are added, what the reminder is, ability to turn off, and so on. A related point concerning notifications is when used to provide users with a record of actions then you can lighten up on lengthy confirmation messages that pop up (toasts in the Android world) used when transactions or actions are sent for processing or into a workflow. Pretty much all the confirmation needs to say is the action is successful along with key data such as dollar amount, customer name, or whatever. I am a user of Android (Nexus S), BlackBerry (Curve), and iOS devices (iPhone 3GS and 4). In my opinion, the best notifications user experience for the enterprise user is offered by Android. Blackberry is good, but not as polished and way clunkier than Android’s. What you get on the iPhone, out of the box, is useless in the enterprise.

  • Updating My Online Boggle Solver Using jQuery Templates and WCF

    With WebForms, each ASP.NET page's rendered output includes a <form> element that performs a postback to the same page whenever a Button control within the form is clicked, or whenever the user modifies a control whose AutoPostBack property is set to True. This model simplifies web page development, but carries with it some costs - namely, the large amount of data exchanged between the client and the server during a postback. On postback the browser sends the values of all of its form fields (including hidden ones, like view state, which may be quite large) to the server; the server then sends back the entire contents of the web page. While there are some scenarios where this amount of information needs to be exchanged, in many cases the user has performed some action that requires far less information to be exchanged. With a little bit of forethought and code we can have the browser and server exchange much less data, which leads to more responsive web pages and an improved user experience. Over the past several weeks I've been writing an article series on accessing server-side data from client script. Rather than rely solely on forms and postbacks, many websites use JavaScript code to asynchronously communicate with the server in response to the page loading or some other user action. The server, upon receiving the JavaScript-initiated request, returns just the data needed by the browser, which the browser then seamlessly integrates into the web page. There are a variety of technologies and techniques that can be employed to provide both the needed server- and client-side functionality. Last week's article, Using WCF Services with jQuery and the ASP.NET Ajax Library, explored using the Windows Communication Foundation, or WCF, to serve data from the web server and showed how to consume such a service using both the ASP.NET Ajax Library and jQuery. In a previous 4Guys article, Creating an Online Boggle Solver, I built an application to find all solutions in a game of Boggle. (Boggle is a word game trademarked by Parker Brothers and Hasbro that involves several players trying to find as many words as they can in a 4x4 grid of letters.) This article takes the lessons learned in Using WCF Services with jQuery and the ASP.NET Ajax Library and uses them to update the user interface for my online Boggle solver, replacing the existing WebForms-based user interface with a more modern and responsive interface. I also used jQuery Templates, a JavaScript-based templating library that is useful for displaying the results from a server-side service. Read on to learn more! Read More >

  • "Half" ssh authorization to a server with git repository

    - by hsz
    Hello ! Currently I have purchased web hosting with ssh access. I have created a git repository on it and if I set my public key in ~/.ssh/authorized_keys file, I have access to that repo, I can push/pull data, etc. This solution allows access for every user that has his public key in authorized_keys file. But there is one thing that I want to avoid. Every user can login to the server too and has access to whole ssh account. Is it possible to create a blacklist of users' keys that will not have an access to ssh ? I see it that way: user logs in to a git - ok, allow for every one user logs in to ssh account ~/.profile file is hooked and called a custom script: check user's public key if public key is in ~/.ssh/blacklist_keys call bash exit/logout Is it possible in any way ?

  • SFTP permission denied on files owned by www-data

    - by Charles Roper
    I have a pretty standard server set up running Apache and PHP. An app I am running creates files and these are owned by the Apache user www-data. Files that I upload via SFTP are owned by my own user charlesr. All files are part of the www-data group. My problem is that I cannot modify or overwrite any of the files via SFTP which are owned by www-data, even though charlesr is part of the www-data group. I can modify the files no problem via a SSH session. So I'm not sure what to do. How do I give my SFTP session permissions to modify www-data owned files? For a bit of background, these are the notes I wrote for myself when setting-up the server: Now set up permissions on `/var/www` where your files are served from by default: $ sudo adduser $USER www-data $ sudo chgrp -R www-data /var/www $ sudo chmod -R g+rw /var/www $ sudo chmod -R g+s /var/www Now log out and log in again to make the changes take hold. The previous set of commands does the following: 1. adds the current user ($USER) to the `www-data` group; 2. changes `/var/www` to belong to the `www-data` group; 3. adds read/write permissions to the group that `/var/www` belongs to; 4. sets the SGID bit on `/var/www`; this final point bears some explaining. And then I go on to explain to myself what setting the SGID bit means (i.e. all files created in /var/www become part of the www-data group automatically). Btw, nothing feels sweeter than going back and reading your own detailed notes on the what, how and why of your own server set up when trying to troubleshoot like this - I recommend it highly to all beginners like myself :-)

  • Overlap of the variable in mysql, my column are set to my query result

    - by foodil
    The question is not clear , let me clarify it: try{ $sql = ' SELECT UserID <==== (***********Used here for query ******) FROM user WHERE Rights != ?'; $stmt = $conn->prepare($sql); $stmt->execute(array('admin')); $result= $stmt->fetchAll(); } catch(PDOException $e) { die ($e->getMessage().'<a href="add.php"> Back</a>'); } foreach ($result as $set) { if ($set['UserID']==$_SESSION['username']) $rights='edit'; else {$rights=$_POST[$set['UserID']];} if (($rights != 'default' || $set['UserID']==$_SESSION['username']) && $_POST['public']==0 ) { $user=$set['UserID']; try { $query="INSERT INTO user_list(UserID <==== (***********Used here for insert ******),ListID,UserRights) VALUES ($user,$lastID,$rights)"; $stmt = $conn->prepare($query); $stmt->execute(); } catch(PDOException $e) { die ($e->getMessage().'<a href="add.php"> Back</a>'); $conn->rollBack(); } } } As you can see the UserID is a query result but it is also the column i need to insert, so when i insert into the table it will casued an error SQLSTATE[42S22]: Column not found: 1054 Unknown column 'UserA_ID' in 'field list' because the column is modify by my query result from: $query="INSERT INTO user_list(UserID,ListID,UserRights) VALUES ($user,$lastID,$rights)"; to: $query="INSERT INTO user_list(query_result_id,ListID,UserRights) VALUES ($user,$lastID,$rights)"; How to fix it ?Thank you.

  • How to pass an argument to a Windows Scheduled Task with spaces in it

    - by Rodney
    I need to set up a Windows Scheduled Task. It accepts 1 parameter/argument which is a path and can contain spaces. My Scheduled task does not work - it "breaks" the parameter up at the first space. If I run it in the Command Prompt I can just wrap the argument in " " and it works fine, however, this does not work in the Scheduled Task UI. e.g. C:\Program Files\xyz\FTP File Transfer\FTPFileTransferTask.exe "C:\Program Files\xyz\The Interface\Folder Path" I have tried wrapping the argument with " " ' ' [ ] () and have tried filling in the spaces with %20, ~1 etc. with no luck. I know of one solution to make a bat file and use " " around my argument but I don't want to add more complexity. I tried it on Windows 7 and Windows 2008 Server and both failed. There seems to be no discussions on this?

    I try to connect SharePoint Online with Dynamics CRM Online using BDC. But without any results. I'll try to using Account's from CRM in SharePoint Online like a list. I mean - when I have 100 account's (customers) in CRM I want to export this account's to SharePoint Online like a list. And when I will bed edited account in CRM the elements in the list will be update (and when I edited element on SharePoint list it will update in CRM). Is there any possibility to connect in this way? If if what I should use - SharePoint Designer 2010, Visual Studio or do this on web interface?

  • Unable to print login-required images in IE

    - by Tim Fountain
    I have some images in a section of a site that require the user to be logged in in order to view. These images are served by a PHP script, which checks the user's login state and if valid, serves the binary data with the appropriate headers. This all works fine. The issue comes when a user tries to print one of these images. In Internet Explorer, when they go to print preview they get the broken image box with a red cross in the corner instead of the actual file. This is what gets printed also. All other browsers can print the images without issue. I have some images elsewhere on the site that are also served via. PHP but these don't require a login. These print fine. The PHP-powered HTML pages on the site that require a login also print fine in IE. It's just login-required images. The user hitting print preview does not seem to result in additional HTTP request to the server for the file. However I do see an additional HTTP request a few seconds later that comes from the same IP (may or may not be related), This request includes no host header, no REQUEST_URI and no user agent. The 'please login' page sends an appropriate 403 header. I've also added a far-in-future expires header to the image response itself to ensure that browsers can serve/print the files from their own cache but this hasn't made any difference. Why can't IE print the images and what else can I do to investigate or fix the problem?

  • Basic clarification about Limited FTP/sFTP users

    - by mattewre
    I would like to get some clarification about the correct way to create limited users to access to my VPS user as WEBSERVER with Nginix. I'm used to NOT install FTP and access via SFTP only. It is ok for every set up? this is what I usually do from to create a limited user called "admin" that should be able to have access via SFTP to the folder with the website data mkdir -p /var/www/mysite.com/ adduser admin adduser admin www-data chown -R root:root /var/www chmod -R 755 /var/www chmod -R 755 /var/www/mysite.com chown -R admin:www-data /var/www/mysite.com/ It seems not to be the correct way, I always have problems with permission when I upload some files (for example with Wordpress in general). I would like to create an user that does work exactly as the one that the "provides" give to their client when they buy an Hosting service (that is a FTP, I would prefer SFTP access). It is for personal user, but I think that a limited user is a lot safer to use then the "root" via SFTP.

  • Base Pages and Interfaces for ASP.NET Pages

    - by geekrutherford
    For quite a while I have been using the concept of base pages when developing pages in ASP.NET applications. It is a wonderful method for exposing common functions to all of your applications pages and also overriding certain events for various purposes (i.e. dynamic themes).  Recently I found out a new developer will be joining my team. This prompted me to review the applications code for readability and ease of maintenance. I began adding comments through out the code behind for all pages within the application. While doing so I noted that I had used common method names for such things as loading data, configuring controls, applying filters, etc.   Bringing a new developer on board, I wanted to make the transition as seamless as possible while also ensuring they follow existing coding practices we already have in place. While I could have created virtual methods for the common page methods allowing them to overridden, what I really needed was a way to ensure the new developer implemented the same methods for each and every page. Thus I created an interface to force the issue.   Now, every page not only inherits the base page class but also implements an interface. This provides every page not only common functions and overridden page events but also imposes rules for implementing certain common methods :-)   Interface   public interface BasePageInterface { /// Configures page based on users security permissions. void CheckPermissions(); /// Configures Filter Form control for current page.  /// Ensure you have set the FilteredGrid and PageAjaxManager properties of the FilterForm control in PageLoad!!!  void ConfigureFilters(); /// Sets event handlers and default settings for controls on the current page. void ConfigureControls(); /// Exports data bound to grid in selected format. void ExportGridData(ExportFormat fmt); /// Loads data and binds to grid. /// Columns are turned on/off in grid depending on tab selected and users permissions.  void LoadData(); }   Page code-behind class definition:   public partial class MyPage : BasePage, BasePageInterface Note, you could not use an abstract class to accomplish this considering C# does not allow for multiple inheritance.  Nor could the base page class be abstract since it needs to inherit from the System.Web.UI.Page class in order to override page events.

  • Log "date -s" command

    - by LinuxPenseur
    Hi, I know that the date -s <STRING> command sets the time described by the string STRING. What i want is to log the above command whenever it is used to set the time into the file /tmp/log/user.log. In my Linux distribution the logging is done by syslog-ng. I already have some logs going into /tmp/log/user.log. This is the content of /etc/syslog-ng/syslog-ng.conf in my system for logging into /tmp/log/user.log destination d_notice { file("/tmp/log/user.log");}; filter f_filter10 { level(notice) and not facility(mail,authpriv,cron); }; log { source(s_sys); filter(f_filter10); destination(d_notice); }; What should i do so that date -s command is also logged into /tmp/log/user.log

  • Some More New ADF Features in JDeveloper 11.1.2

    - by Steven Davelaar
    The official list of new features in JDeveloper 11.1.2 is documented here. While playing with JDeveloper 11.1.2 and scanning the web user interface developer's guide for 11.1.2, I noticed some additional new features in ADF Faces, small but might come in handy:  You can use the af:formatString and af:formatNamed constructs in EL expressions to use substituation variables. For example: <af:outputText value="#{af:formatString('The current user is: {0}',someBean.currentUser)}"/> See section 3.5.2 in web user interface guide for more info. A new ADF Faces Client Behavior tag: af:checkUncommittedDataBehavior. See section 20.3 in web user interface guide for more info. For this tag to work, you also need to set the  uncommittedDataWarning  property on the af:document tag. And this property has quite some issues as you can read here. I did a quick test, the alert is shown for a button that is on the same page, however, if you have a menu in a shell page with dynamic regions, then clicking on another menu item does not raise the alert if you have pending changes in the currently displayed region. For now, the JHeadstart implementation of pending changes still seems the best choice (will blog about that soon). New properties on the af:document tag: smallIconSource creates a so-called favicon that is displayed in front of the URL in the browser address bar. The largeIconSource property specifies the icon used by a mobile device when bookmarking the page to the home page. See section 9.2.5 in web user interface guide for more info. Also notice the failedConnectionText property which I didn't know but was already available in JDeveloper 11.1.1.4. The af:showDetail tag has a new property handleDisclosure which you can set to client for faster rendering. In JDeveloper 11.1.1.x, an expression like #{bindings.JobId.inputValue} would return the internal list index number when JobId was a list binding. To get the actual JobId attribute value, you needed to use #{bindings.JobId.attributeValue}. In JDeveloper 11.1.2 this is no longer needed, the #{bindings.JobId.inputValue} expression will return the attribute value corresponding with the selected index in the choice list. Did you discover other "hidden" new features? Please add them as comment to this blog post so everybody can benefit.
