  • EHCache on Coldfusion 9 - can I create multiple caches or disable it?

    - by ciaranarcher
    Hi all. We have been using EHCache with CF8 for a while now with no issues. We are now moving to CF 9 and it seems that the baked-in version of EHCache with CF 9 is actually conflicting with our EHCache setup. So is there: Any way to disable the baked-in version of EHCache? This would be a temporary solution. If we use the CF9 baked-in caching, is there any way to specify more than one cache in ehcache.xml and most importantly, to put into that specific cache via the tag? Many thanks in advance.

  • Rails - how do you create a user index page like stack overflows with multiple tabs whilst keeping t

    - by adam
    On stackoverflow in the users profile area there are many tabs which all display differing information such as questions asked and graphs. Its the same view though and im wondering hows its best to achieve this in rails whilst keeping the controller skinny and logic in the view to a minimum. def index @user = current_user case params[:tab_selected] when "questions" @data = @user.questions when "answers" @sentences = @user.answers else @sentences = @user.questions end respond_to do |format| format.html # index.html.erb nd end but how do i process this in the index view without a load of if and else statments. And if questions and answers are presented differently whats the best way to go about this.

  • How to create updateable panel using AjaxLink of Wicket?

    - by Arne
    I try to realize a link (in fact many links) that update a table in an website using an AjaxLink of Wicket. But I fail, the table is never updated (I have "setOutputMarkupId(true)" and call "addComponent", but there must be something other thats wrong). How can I realize a panel with a number of links and a table that displays dynamic data, dependent on the link clicked? Can someone give an example (Maybe two links, when the first one is clicked the table displays two random numbers from 1-10, when the second is clicked the table displays random numbers from 1-100)? Without reloading the entire page, but only the html for the table?

  • Is it possible to create a Windows shortcut using PHP?

    - by Drarok
    I'm writing a script to tidy up a bunch of media spread across my hard drives, and it works pretty well so far at home (on my Mac) as I use symlinks in a directory to give the impression that everything is organised in one location, whilst the actual data is spread across the 4 drives. Unfortunately, I have to use Windows at work, and of course there's no symlink support there until PHP 5.3 (and I assume that requires Vista as that's when the command-line tool "mklink" first appeared). As a workaround, I considered creating a shortcut, but I can't find a way of doing it. Is it possible, or is there a better solution I've not considered?

  • How do I create multiple submit buttons for the same form in Rails?

    - by Angela
    I need to have multiple submit buttons. I have a form which creates an instance of Contact_Call. One button creates it as normal. The other button creates it but needs to have a different :attribute value from the default, and it also needs to set the attribute on a different, but related model used in the controller. How do I do that? I can't change the route, so is there a way to send a different variable that gets picked up by [:params]? And if I do then, what do I do in the controller, set up a case statement?

  • How can I create a simple message box in Python?

    - by Carson Myers
    I'm looking for the same effect as alert() in JavaScript. I wrote a simple web-based interpreter this afternoon using Twisted.web. You basically submit a block of Python code through a form, and the client comes and grabs it and executes it. I want to be able to make a simple popup message, without having to re-write a whole bunch of boilerplate wxPython or TkInter code every time (since the code gets submitted through a form and then disappears). I've tried tkMessageBox: import tkMessageBox tkMessageBox.showinfo(title="Greetings", message="Hello World!") but this opens another window in the background with a tk icon. I don't want this. I was looking for some simple wxPython code but it always required setting up a class and entering an app loop etc. Is there no simple, catch-free way of making a message box in Python?

  • Recommendations for C# controls that can be used to create a hierarchical list of prioritised items?

    - by Mendokusai
    I need to be able to display and edit a hierarchical list of tasks in a C# app. It can either be a Windows form app, or ASP.NET. Basically, I want similar behaviour to the way Microsoft Project handles tasks. The control would need to: 1) Maintain a list of items made up of several fields 2) Each item can have a number of children (at least 3 levels of nesting) 3) It needs to be very easy to change the parents/children of an item 4) It needs to be very easy to edit the fields (as fast as changing cells in Excel) 5) It needs to be very easy to reorder the items by dragging and dropping or cut and paste 6) If I can easily connect the control to a database, even better Anyone got any recommendations for controls for me to look at?

  • How do you create multiple versions of an ActiveX control?

    - by Peter Ruderman
    Hopefully this is a straightforward question, but googling has proved fruitless (and frustrating, to say the least). Links to good documentation would be greatly appreciated. Here's the problem. We have a web application with an associated ActiveX control. (The control wraps a crufty old MFC application if it matters.) Moving forward, we expect to release multiple versions of this application, and each will have a corresponding version of the control. If someone accesses two versions of the web application, then that user should end up with two different versions of the control on his system. (The controls should play nice and not clobber each other.) In addition, I want to automate this process. Our system has a global version number that applies to all components. If we change the version number, the next build should produce a new version of the control. What's the best way to do this?

  • How do I create rows with alternating colors for a UITableView on iPhone?

    - by Mat
    Hi all, i would to have alternate 2 colors of rows, like the first black, the second white, the third black, etc, etc... my approach is like a basic exercise of programming to calculate if a number is odd number or not: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; cell = ((MainCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]); if (cell==nil) { NSArray *topLevelObjects=[[NSBundle mainBundle] loadNibNamed:@"MainCell" owner:self options:nil]; for (id currentObject in topLevelObjects){ if ([currentObject isKindOfClass:[UITableViewCell class]]){ if ((indexPath.row % 2)==0) { [cell.contentView setBackgroundColor:[UIColor purpleColor]]; }else{ [cell.contentView setBackgroundColor:[UIColor whiteColor]]; } cell = (MainCell *) currentObject; break; } } }else { AsyncImageView* oldImage = (AsyncImageView*) [cell.contentView viewWithTag:999]; [oldImage removeFromSuperview]; }return cell; The problem is that when i do a rapid scroll, the background of cells become like the last 2 cell black, the first 2 cell white or something like this, but if i scroll slow works fine. I think the problem is the cache of reusableCell. Any ideas? TIA

  • How do I create a ListBox In Ext-GWT ?

    - by Salvin Francis
    Plain and Simple, I want to use a Listbox in my project, The demo here: http://www.extjs.com/examples shows no answer, In fact, I really hate it when companies show-off their 'complex' widgets in this manner and fail to show the most basic of all widgets. For example, I discovered class SimpleComboBox over the net till then I assumed that we required a class to contain list store, etc...

  • Can I create class properties during __new__ or __init__?

    - by 007brendan
    I want to do something like this. The _print_attr function is designed to be called lazily, so I don't want to evaluate it in the init and set the value to attr. I would like to make attr a property that computes _print_attr only when accessed: class Base(object): def __init__(self): for attr in self._edl_uniform_attrs: setattr(self, attr, property(lambda self: self._print_attr(attr))) def _print_attr(self, attr): print attr class Child(Base): _edl_uniform_attrs = ['foo', 'bar'] me = Child() me.foo me.bar #output: #"foo" #"bar"

  • Is C# WebAPI worth it? Can I use standart MVC4 to create my API?

    - by Steve
    I need to build a massive API and I'm trying out WebAPI instead of default MVC4 projects and it seems that it just makes things more difficult. Can have only 4 methods in controller Get, Post, Put, Delete, if I want more I need to modify route for that particular method FluentValidation won't work with WebAPI so I need to use DataAnnotations which I really don't want to. Can't use dynamic return data-types My question is: Would it really be that bad if I would use MVC4 project and use default ActionResults that return Json? What are real advantages of using WebAPI, why did they even made them in the first place if you can easily convert your project to API?

  • How to create view model without sorting collections in memory.

    - by Chevex
    I have a view model (below). public class TopicsViewModel { public Topic Topic { get; set; } public Reply LastReply { get; set; } } I want to populate an IQueryable<TopicsViewModel> with values from my IQueryable<Topic> collection and IQueryable<Reply> collection. I do not want to use the attached entity collection (i.e. Topic.Replies) because I only want the last reply for that topic and doing Topic.Replies.Last() loads the entire entity collection in memory and then grabs the last one in the list. I am trying to stay in IQueryable so that the query is executed in the database. I also don't want to foreach through topics and query replyRepository.Replies because looping through IQueryable<Topic> will start the lazy loading. I'd prefer to build one expression and have all the leg work done in the lower layers. I have the following: IQueryable<TopicsViewModel> topicsViewModel = from x in topicRepository.Topics from y in replyRepository.Replies where y.TopicID == x.TopicID orderby y.PostedDate ascending select new TopicsViewModel { Topic = x, LastReply = y }; But this isn't working. Any ideas how I can populate an IQueryable or IEnumerable of TopicsViewModel so that it queries the database and grabs topics and that topic's last reply? I am trying really hard to avoid grabbing all replies related to that topic. I only want to grab the last reply. Thank you for any insight you have to offer.

  • How can I create masking like this in AS3?

    - by Ólafur Waage
    I've worked a little bit with masks in AS3 but I'm not sure how I can do this with masks. I have two swf files that I have imported onto the Library as MC's with class names. One of the files is the start image and the other is the end image. The transition is a slide transition from the start image to the end image. You can think of the transition like in this example. But is it possible to do a slide transition like this using two swf's and "slide transitioning" between them?

  • Can you create a HIPAA compliant Amazon S3 Web Application?

    - by xkingpin
    I am facing some questions when trying to design an S3 application using ASP.NET MVC and trying to stay HIPAA compliant. My initial plan was to require an SSL connection to my web server, encrypt the images on my server, then send them to s3 using my private keys. Here's my obvious concerns: You cannot store unencrypted images in any temporary file cache when client views images within the browser. Even if I setup an ashx to generically handle the image in memory, couldn't this get stored in cache? Saying the images will be encrpyted because you will be connecting to my server via https still does not guarantee all browsers will not cache data. It's not possible to even consider the "Query String" with expiration option since data will be encrypted before being stored on disk at s3, and will again be decrypted at my server in memory. I think my only option would be to write/purchase some sort of ActiveX component that will not expose the image as a simple html image source or write my app as a client side WinForm application.

  • Which design pattern should be used to create an emulator?

    - by Facon
    I have programmed an emulator, but I have some doubts about how to organizate it properly, because, I see that it has some problems about classes connection (CPU <- Machine Board). For example: I/O ports, interruptions, communication between two or more CPU, etc. I need for the emulator to has the best performance and good understanding of the code. PD: Sorry for my bad English. EDITED - Asking for multiple patterns.

  • How hard is it to create a not-so-random number generator?

    - by Duracell
    Backstory: So I was driving to band practice this evening. My car has a USB port where you can plug in a USB stick with MP3 files on it and the stereo will play them. I have about 100 MP3s on my stick so I pushed the 'Random' button. So from here to band practice, it played: Track 22 Track 45 Track 4 Track 11 Track 87 Track 66 Track 98 Then on the way home, it played Track 16 Track 27 Track 33 And then I stopped at the petrol station. I filled up, got back in the car and the stereo fired up again. It played Track 22 Track 45 Track 4 Track 11 Track 87 I thought, WTF? What's with this 'random' generator? What are they using as a seed, if not time? Is a car stereo so memory-tight that it can't even use the C stdlib? Does anyone know how this kind of thing happens?
