  • Set cookie value before view loaded in MVC?

    - by James123
    I need to set a cookie value before my view called. otherwise I have to refresh the page to get cookie value in the view. The problem here is the value of cookie will get in controller. [HttpGet] [Route("Abstract/{meetingCode}")] [AllowAnonymous] public ActionResult Index(string meetingCode) { var meetingAbstract = new MeetingAbstract(); meetingAbstract.Meeting = _abstractContext.GetMeetingWithMeetingCode(meetingCode); if (meetingAbstract.Meeting != null) { var cookie = new HttpCookie("_culture"); cookie.Value = meetingAbstract.Meeting.language.language_locale_code;//"en-US"; cookie.Expires = DateTime.Now.AddDays(365); cookie.Path = "/"; this.ControllerContext.HttpContext.Response.Cookies.Add(cookie); ... Any other way without refresh the page again to set cookie value?

  • How to avoid "incomplete implementation" warning in partial base class

    - by garph0
    I have created a protocol that my classes need to implement, and then factored out some common functionality into a base class, so I did this: @protocol MyProtocol - (void) foo; - (void) bar; @end @interface Base <MyProtocol> @end @interface Derived_1 : Base @end @interface Derived_2 : Base @end @implementation Base - (void) foo{ //something foo } @end @implementation Derived_1 - (void) bar{ //something bar 1 } @end @implementation Derived_2 - (void) bar{ //something bar 2 } @end In this way in my code I use a generic id<MyProtocol>. The code works (as long as Base is not used directly) but the compiler chokes at the end of the implementation of Base with a warning: Incomplete implementation of class Base Is there a way to avoid this warning or, even better, a more proper way to obtain this partially implemented abstract base class behavior in Objc?

  • Why Is It That Generics Constraint Can't Be Casted to Its Derived Type?

    - by Ngu Soon Hui
    It is quite puzzling to find out that Generics Constraint Can't Be Casted to Its Derived Type. Let's say I have the following code: public abstract class BaseClass { public int Version { get { return 1; } } public string FixString { get; set; } public BaseClass() { FixString = "hello"; } public virtual int GetBaseVersion() { return Version; } } public class DeriveClass: BaseClass { public new int Version { get { return 2; } } } And guess what, this method will return a compilation error: public void FreeConversion<T>(T baseClass) { var derivedMe = (DeriveClass)baseClass; } I would have to cast the baseClass to object first before I can cast it to DerivedClass. Seems to me pretty ugly. Why this is so?

  • Do I really need to reboot for AD changes to be applied?

    - by stimms
    Every time I request a permission change the IT group at my company instructs me to wait 20 minutes and reboot the computer. I cannot believe that in this day and age you still need to reboot the computer to clear whatever cache stores the permissions locally. It feels like something out of the NT 4 days. Do you actually still need to reboot the computer? Is a logout/login sufficient? Is there still a long time(20 minutes) for the changes to propagate through the AD tree?

  • Shell script to fix bad filenames? [closed]

    - by Ze'ev
    I'm IT at my small firm; and, despite my dire warnings, everyone puts files on the server with awful names, including leading & trailing spaces, bad characters (including \ ; / + . < > - etc!) They do this by accessing the (FreeBSD/FreeNAS) server via AFP on Macs, so no part of the system complains. Is there a script I can use to go through an entire directory tree and fix bad filenames? Basically replace all spaces & bad ASCII with _ ... and if a file already exists, just slap a _2 or something on the end. I don't suppose there's a way to get the system to enforce good filenaming conventions, is there?

  • Unit Testing: hard dependency MessageBox.Show()

    - by Sean B
    What ways can the SampleConfirmationDialog be unit tested? The SampleConfirmationDialog would be exercised via acceptance tests, however how could we unit test it, seeing as MessageBox is not abstract and no matching interface? public interface IConfirmationDialog { /// <summary> /// Confirms the dialog with the user /// </summary> /// <returns>True if confirmed, false if not, null if cancelled</returns> bool? Confirm(); } /// <summary> /// Implementation of a confirmation dialog /// </summary> public class SampleConfirmationDialog : IConfirmationDialog { /// <summary> /// Confirms the dialog with the user /// </summary> /// <returns>True if confirmed, false if not, null if cancelled</returns> public bool? Confirm() { return MessageBox.Show("do operation x?", "title", MessageBoxButton.YesNo, MessageBoxImage.Question) == MessageBoxResult.Yes; } }

  • Can not start Apache 2.2.22 in Fedora 15

    - by Roderik
    I am trying to start Apache 2.2.22 under Fedora 15 on my local machine. After fixing some errors related to missing modules, httpd -t will just give me 'Syntax OK'. However when I try to start apache as the root user: service httpd start it still returns: Starting httpd (via systemctl): Job failed. See system logs and 'systemctl status' for details. [FAILED] When entering systemctl I don't see any extra information other than: httpd.service loaded failed failed LSB: start and stop Apache HTTP Server So I wonder where to look now to get this back up and running.

  • Is there a design pattern for this ?

    - by ytrewq
    I have a component that needs to call a specific service depending on the input it receives. So my component has to look at the input and based on a configuration that says "for this input call this service with this data" needs to call the proper service. The services have a common signature method and a specific one (each). I thought about an abstract class that includes the signatures for all three methods. The implementation for the two services will override all three methods (throwing NotImplementedException for the methods that are not supported by current service). A component that could be initialized with a map (that for each input type will have the type of the service to be called) will also be defined. Do you have a better approach to cope this scenario ?

  • How to troubleshoot Application Popup issues 0XC0000142 and 0XC000009a

    - by DotDot
    I am running randomly into 1 of these popups when our application runs. The machines range from 8GB/8Core to 24GB/24Core and run Windows Server 2008 R2. The application is a bunch of perl scripts and exe's that are expected to utilitize the server well. The process tree can be quite deep (5-6 child levels) and quite broad (60-70 level 1 processes). We hit this issues every 1% run on random machines. The application stalls on popup, unless someone clicks the damn button. The event log reads as cmd.exe - "Failed to initialize app. Click OK to close app" How could I reliably repro these issues?

  • Per-user vhost logging

    - by kojiro
    I have a working per-user virtual host configuration with Apache, but I would like each user to have access to the logs for his virtual hosts. Obviously the ErrorLog and CustomLog directives don't accept the wildcard syntax that VirtualDocumentRoot does, but is there a way to achieve logs in each user's directory? <VirtualHost *:80> ServerName *.example.com ServerAdmin [email protected] VirtualDocumentRoot /home/%2/projects/%1 <Directory /home/*/projects/> Options FollowSymlinks Indexes IndexOptions FancyIndexing FoldersFirst AllowOverride All Order Allow,Deny Allow From All Satisfy Any </Directory> Alias /favicon.ico /var/www/default/favicon.ico Alias /robots.txt /var/www/default/robots.txt LogLevel warn # ErrorLog /home/%2/logs/%1.error.log # CustomLog /home/%2/logs/%1.access.log combined </VirtualHost>

    How can I parse data from inside a tag with Applescript? I know Applescript has the words 3 thru -2 of myTextVariable syntax - but how would I use it to be sure I am just getting This is my text from the tags below? <p>This is my text</p> or <p class="new">This is my text</p> or <h1>This is my text</h1> or <content class="new" id="content">This is my text</content>

  • Why my browsers display XML files as blank pages?

    - by n1313
    Every time I open an XML file, all I get is blank page instead of tag tree. The file itself is correct and loads okay, I can see it via View Source or in the Firebug. I've tried turning off all my addons and tried running Firefox in safe mode, but the problem was not solved. I'm guessing that I've messed up my configuration somehow and Firefox now tries to render XML files as HTML ones. I've tried googling, but with no success. Help, please? UPD: example file: http://lj.lain.ru/3/1273657698603.sample.xml Also I've noticed that somehow all of the browsers on the machine are now acting the same, so I'm changing the question accordingly

  • Why should I use $[ EXPR ] instead of $(( EXPR ))?

    - by qdii
    On the paragraph explaining arithmetic expansion, Bash's user guide uncovers 2 different ways of evaluating an expression, the first one uses $((?EXPRESSION?)) and the second one uses $[?EXPRESSION?]. The two ways seem pretty similar as the only difference I have found is: $[?EXPRESSION?] will only calculate the result of EXPRESSION, and do no tests: Yet, I am intrigued because the same document recommends using $[?EXPRESSION?] rather than $((?EXPRESSION?)). Wherever possible, Bash users should try to use the syntax with square brackets: Why would you want that if less tests are being done?

I'm trying this in terminal but: sudo apt-get install adobe-flashplugin Reading package lists... Done Building dependency tree Reading state information... Done E: The package adobe-flashplugin needs to be reinstalled, but I can't find an archive for it. I also tried the update manager, but I get something about partial upgrade but that thing also isnt working, and I get a message that I have to install it manually or I remove it completely. So, how can I remove it completely and then I will install it clean again from the beggining?

  • How to create GUI as inner class with WindowBuilder

    - by Tim Kemp
    I would like to use WindowBuilder in Eclipse to construct Swing GUIs. The JPanels I need to build will be inner classes in a non-GUI wrapper, like so: public class MyWrapper extends MyBaseClass { ... class MyPanel extends JPanel { ... } } So my question is this: can I construct MyPanel using WindowBuilder? If so, how should I set it up? If anyone is interested, the wrapper is an abstract base class which the plug-ins I am developing for my app must extend; deployment concerns mean that it's not really practical to put the GUIs in a separate JAR either so I pretty much have to do it this way. My current workflow, which is awful, is to build the GUI in NetBeans and paste the entire generated class into Eclipse where I connect it up to the methods in my wrapper. I am very hopeful that WindowBuilder will let me work more reliably and efficiently if I can trick it into generating code in MyPanel, not MyWrapper. Thanks

  • Setting a mapped drive in Virtual hosts causes apache to not start

    - by darksoulsong
    I´m trying to set a virtual host on my windows 7 machine. The folder I want to point to is located on a centOS machine and the folder path is Z:\Websites\Online\MyClient\Site. But something strange happens when I set the document root like this: DocumentRoot "Z:\Websites\Online\MyClient\Site" Apache do not restarts after that. When I take a look at the log, there is an error pointing to that line, where I added the path to the folder: Syntax error on line 48 of C:/Program Files/Zend/Apache2/conf/extra/httpd-vhosts.conf: DocumentRoot must be a directory. There must be a way to make it work like this, by setting an Apache Installation on a machine and pointing it to a folder located on another computer, right? My hosts file is set like this: 172.17.10.1\Data\Websites\Online\MyClient\Site MyClient.local ANY HELP would be VERY appreciated.

  • Java and Sendmail HELO requires domain address

    - by ealgestorm
    I am trying to set up emailing from a java web application hosted on a linux server (Cent OS) in apache. Sendmail is working fine from the command line as root on localhost but when trying to send emails from the java web app (also on the same server from localhost) the following java exception is thrown. 501 5.0.0 HELO requires domain address EDIT: I have read that some people have found this is due to an incorrect hosts entry currently the hosts file contains 127.0.0.1 Centos-VPS localhost.localdomain localhost and i'm not sure what the Centos-VPS bit at the start is for but this is a clients hosted server so don't really want to break stuff EDIT see the RFC is helpful ... 501 Syntax error in parameters or arguments Now I know what the problem is! (note the sarcasm people.)

  • imageview draw issue with asynctask

    - by alexb
    Have the following asynctask that i'm using to download some images. Works fine except for the very first image, which doesn't always appears unless I do something like move to the next image and then back again. public class DownloadImageTask extends AsyncTask { static ImageView _imageView=null; public DownloadImageTask(ImageView ctl){ _imageView=ctl; } protected void onPostExecute(Bitmap result) { _imageView.setImageBitmap(result); } ... } I thought this might be an issue with updating the UI on a background thread, so I reworked this using an abstract class that invokes a method on the UI thread that calls .setImageBitmap() but I still get the same behaviour - works fine for all images except the first, unless I move to the next image and back again. Is there a way to force a redraw on the imageview after i set the image?

  • "Overriding" instance variables in subtype: Possible risks?

    - by sebastiangeiger
    Say I had a class SuperClass and two subclasses SubClassA and SubClassB that inherit from SuperClass. abstract class SuperClass{ ... List someList; ... } class SubClassA extends SuperClass{ ... List<String> someList; ... } class SubClassB extends SuperClass{ ... List<Integer> someList; ... } That way it is convenient because I can get someList.size() in Superclass and have Typesafety in the Subclasses. The problem is that it does not "feel" right, can you think of potential hazards this apporach has that I am not aware of?

  • what is the underlying data structure of a set c++?

    - by zebraman
    I would like to know how a set is implemented in C++. If I were to implement my own set container without using the STL provided container, what would be the best way to go about this task? I understand STL sets are based on the abstract data structure of a binary search tree. So what is the underlying data structure? An array? Also, how does insert() work for a set? How does the set check whether an element already exists in it? I read on wikipedia that another way to implement a set is with a hash table. How would this work?

  • Actionscript 3.0 cross-project folder/package structure best practise

    - by dr_tchock
    I'm currently looking at structuring my teams projects into a consistent manner that properly utilises packages and is easily version-controlled (via SVN). I'm interested in any 'best practise' with regards to project structuring and how to use consistent packaging without lumping everything into a gigantic com.domainname.projects folder structure whilst maintaining that package structure. I'm also keen to use the src/bin/lib folder structure within each project. I guess I'm asking 'how do you do it?' and 'why?'. Sorry if this is a bit abstract for Stack Overflow but you guys give the best answers I've found.
