  • Creating/compling .net data class within an application

    - by MrTelly
    Is there a pattern, Xml structure, architecture technique we can use to create simple data holder class code that we can deserialise to/from and do that at runtime? We're in the early design stage of a .Net project and one of our goals is to make the resulting system extensible through configuration without needing a developer. We need to support new sources of data, typcially delivered as Xml messages. Currently we convert/deserialise the messages into simple classes and then use an already existing language which can manipulate those classes as we need. That works well when you have a developer to map the Xml to simple class, create the class and then write the deserialisation, but it's not extensible for for an administrator. Our target user audience is high end DBA and/or network admin - people who can handle Xml but may not know C#.

  • Which data structure for List of objects + datagrid wiev

    - by Martin
    Hi, I have to develop a code which will store a list of objects, as example below 101, value 11, value 12, value 13 ...etc 102, value 21, value 22, value 23 ...etc 103, value 31, value 32, value 33 ...etc 104, value 41, value 42, value 43 ...etc Now, the difficulty is, that first column is an identifier, and whole table should always be sorted by it. Easy access to each element is required. Additionally, list should be easily updated, and extended by adding element at the end as well as in front and still keep being sorted by first column. Finally, I would like to be able to display values of the above in datagridview. What is most important is a performance of the implementation, as rows will be updated many times per second, and datagridview should be able to display all changes immediately. I was thinking about creating class for the values, and then a Dictionary but encountered a problem with displaying values in gridview. What would be the most optimal way of implementing the code? Thanks in advance Martin

  • AJAX server calls on a JSF-centric app

    - by Konrad Garus
    I'm building a JSF 2 application. I wanted to integrate it with jQuery, e.g.: $.getJSON(contextPath + '/something', function(data) { // ... }); I need contextPath/something to return data in JSON. How can I do it? I know I can assign another servlet to this URL, but this approach does not seem to scale well. One could use a more scalable approach with a front end controller (e.g. Spring Web MVC), but I really wanted to write this in Java Enterprise stack. What other options are there?

  • Concatenating NSString inside of UITextView

    - by Jason
    I'm some trouble adding strings together for a UITextView in my app. The method I've been using is this (header) #import <UIKit/UIKit.h> @interface calculatorViewController : UIViewController { IBOutlet UITextView *output; } -(IBAction)b1; @property(nonatomic, copy) NSString *output; @end (main) #import "calculatorViewController.h" @implementation calculatorViewController -(void)b1 { [output stringByAppendingString:@"hi"]; } The problem I've been having with this method is when I use the button the app crashes. The warning it gives me is 'UITextView' may not respond to '-stringByAppendingString:' When I replace output with at string it works though and that confused me. Any suggestions? Am I doing something wrong? Thanks

  • Festival TTS showing SIOD:ran out off storage message

    - by Peeyush
    Hello i am designing a front end for Festival TTS using it's C++ API Everything is working fine in my programme but i have a problem that i am giving a drop down option to user to select other languages when user select a language from drop down then festival tts shows a message on console saying: SIOD:ran out of storage This message only shows if the text given to festival TTS is greater then 5 or 6 lines. i think this message comes because SIOD's heap is not free when i am going to call a new language. So please tell me the solution of this problem. Thanks

  • Can PHP Perform Magic Instantiation?

    - by Aiden Bell
    Despite PHP being a pretty poor language and ad-hoc set of libraries ... of which the mix of functions and objects, random argument orders and generally ill-thought out semantics mean constant WTF moments.... ... I will admit, it is quite fun to program in and is fairly ubiquitous. (waiting for Server-side JavaScript to flesh out though) question: Given a class class RandomName extends CommonAppBase {} is there any way to automatically create an instance of any class extending CommonAppBase without explicitly using new? As a rule there will only be one class definition per PHP file. And appending new RandomName() to the end of all files is something I would like to eliminate. The extending class has no constructor; only CommonAppBase's constructor is called. Strange question, but would be nice if anyone knows a solution. Thanks in advance, Aiden (btw, my PHP version is 5.3.2) Please state version restrictions with any answer.

  • C# Dynamic Query Without A Database Model

    - by hitopp
    I have been searching the web for a solution to dynamic queries. I have found many different solutions (e.g. Linq to Sql, Dynamic Linq Expressions, Dynamic Query), but all of these solutions involve some sort of previous knowledge of the database (like a model in code). Maybe what I am asking is way off the deep end, but is there any possible way to dynamically query a database without a model? For example, a database has a Customers table with the following columns: CustomerID Name FavoriteColor I want to create a query as SELECT Name FROM Customers WHERE @0 = @1, where the two placeholders are populated dynamically. The resulting data does not tie to a model class and I would prefer to use some sort of framework to build the queries, not simple string concatenation. The System.Linq.Dynamic namespace came really close to fulfilling this request, but it uses a database model. I realize this is crazy, but I was just curious.

  • turning text into image - PHP/GD - save image

    - by Phil Jackson
    Hi, I'm using this script to simply create an image from text. What I would like to know is how to save the image instead of printing straight to browser; // an email address in a string $string = $post[$key]; // some variables to set $font = 4; $width = ImageFontWidth($font) * strlen($string); $height = ImageFontHeight($font); // lets begin by creating an image $im = @imagecreatetruecolor ($width,$height); //white background $background_color = imagecolorallocate ($im, 255, 255, 255); //black text $text_color = imagecolorallocate ($im, 0, 0, 0); // put it all together $image = imagestring ($im, $font, 0, 0, $string, $text_color); I know its probably just one line of code at the end but im not sure which GD function to use. Any help would be much appreciated, Regards, Phil.

  • acts_as_taggable_on and auto_complete returning no results

    - by Sean Johnson
    I'm using acts_as_taggable_on in a model, and am trying to implement the auto_complete plugin. It seems as though I have everything hooked up correctly, but the search isn't returning any results. Here's what I have so far: In the view: <%= text_field_with_auto_complete(:link, :tag_list, {}, {:tokens => ','}) %> In the controller: def auto_complete_for_link_tag_list @tags = Link.tag_counts_on(:tags).where('tags.name LIKE ?', params[:link][:tag_list]) render :inline => "<%= auto_complete_result(@tags, 'name') %>", :layout => false logger.info "#{@tags.size} tags found." end The logger keeps returning 0 tags, and nothing shows up in the view (yeah, the layout includes the javascript defaults). Any thoughts or advice would be awesome.

  • Can you open an SPSite object while being within a different site collection?

    - by Chris Stewart
    I'm working on creating a common navigation experience across two site collections in MOSS 2007. I've looked around for various solutions and haven't found anything that fits. Our navigation is dynamic and driven by a number of factors, including audience targeting. Most of what I've found relates to having static XML and that just won't work for our requirements. What I'm down to at the moment is just getting a navigation item from site collection A while in the context of site collection B. Are there reasons I shouldn't be able to just open a navigation item from site collection A and gets its audience? Certainly there could be permissions problems on my end, or code related issues, or things that are in my control. What I'm wondering is if there's something inherent to SharePoint that would not allow this. Something I don't have control over which would force me to travel a different path.

  • Is it bad practice to use python's getattr extensively?

    - by Wilduck
    I'm creating a shell-like environment. My original method of handleing user input was to use a dictionary mapping commands (strings) to methods of various classes, making use of the fact that functions are first class objects in python. For flexibility's sake (mostly for parsing commands), I'm thinking of changing my setup such that I'm using getattr(command), to grab the method I need and then passing arguments to it at the end of my parser. Another advantage of this approach is not having to update my (currently statically implemented) command dictionary every time I add a new method/command. My question is, will I be taking a hit to the efficiency of my shell? Does it matter how many methods/commands I have? I'm currently looking at 30 some commands, which could eventually double.

  • Is there a method I can use across controllers and if so, how do I use it?

    - by Angela
    I have several controllers that take an instance of different classes each (Email, Call, Letter, etc) and they all have to go through this same substitution: @email.message.gsub!("{FirstName}", @contact.first_name) @email.message.gsub!("{Company}", @contact.company_name) @email.message.gsub!("{Colleagues}", @colleagues.to_sentence) @email.message.gsub!("{NextWeek}", (Date.today + 7.days).strftime("%A, %B %d")) @email.message.gsub!("{ContactTitle}", @contact.title ) So, for example, @call.message for Call, @letter.message for Letter, etcetera. This isn't very dry. I'd like to have something like def messagesub(asset) @asset.message.gsub.... end or something like that so I can just use messagesub method in each controller.

  • Rails Devise: How to access sign up page after signed in?

    - by Junior rails programmer
    hi All, I am new with rails and i am using "devise" gem for authentication purposes. At first i add a new user through default sign up page (E.g./users/sign_up) Then, i made "sign_up" page only available to signed_in users by following instructions from Devise before filter that prevents access to "new_user_registration_path" unless user is signed-in Now, after sign in process when i try open sign up page it always directs me to root_path! How can i access sign up page? My "roots.rb" file as follows: Example::Application.routes.draw do devise_for :users, :controllers => { :registrations => 'registrations'} resources :companies resources :orders resources :customers root :to => "welcome#index" end Thank you all!

  • How Do I Remove The First 4 Characters From A String If It Matches A Pattern In Ruby

    - by James
    I have the following string: "h3. My Title Goes Here" I basically want to remove the first 4 characters from the string so that I just get back: "My Title Goes Here". The thing is I am iterating over an array of strings and not all have the h3. part in front so I can't just ditch the first 4 characters blindly. I have checked the docs and the closest think I could find was chomp, but that only works for the end of a string. Right now I am doing this: "h3. My Title Goes Here".reverse.chomp(" .3h").reverse This gives me my desired output, but there has to be a better way right? I mean I don't want to reverse a string twice for no reason. I am new to programming so I might have missed something obvious, but I didn't see the opposite of chomp anywhere in the docs. Is there another method that will work? Thanks!

  • Svn merging trunk and branches

    - by Darko Petreski
    Hi All, I have a huge project. I need to make a branch - this will be version 2 of the project, but I also need to keep the trunk and change it in parallel with the branch 1 as bug fix to the version 1. I need to merge bug fixes from the trunk to the branch 1 while adding new features to the branch. At the end I need to merge all changes back in the trunk and make new tag from it. So I need bug fix for version 1, new branch for version 2 and of course merging bug fixes in the version 2. I am using svn but the svn makes problems all the time. I cannot merge anything without conflicts. Can someone give me an advice what to do? Regards

If not what type of errors can be handled in System Defined Unnamed Exception using PRAGMA EXCEPTION_INIT.

  • Webservice and ORM Framework?

    - by Sebastian
    Does anybody know a good web framework that includes an ORM mapper and allows straight forward implementation of web services? I'm looking for a framework written in PHP or C++. I'm looking for the following features (not all of them required, some will do nicely) data definition in one place used by database and web service WSDL generation XML output/JSON output boilerplate code generation So what I would like is a framework that let's me specify the objects, the web service functions on those objects and then generate everything that is required leaving me to fill the business logic (connecting the database to the web service). Anything like that out there? Background information for why I need this: I'm looking into creating a web project: the client is a rich web application that fetches all its data using AJAX. It will be completely custom made using only a low level javascript library. The server back end is supposed to serve static content and javascript (basically the rich web application) and to provide a RESTful web service API (which I would like to implement using aforementioned framework).

  • Flex Builder 3 executing old source codes

    - by Gorro
    I'm facing this problem again and again, but can't find any solution (except mine, which is not as a good one I guess). Don't know why, sometimes Flex Builder executes old source codes after making changes. While debugging I see how it steps through a source (e.g. changing local variables) which does not exist (even if I delete all that block or function). My way to solve that is to delete the project (backing up the source codes of course) and create a new one, add the backed up sources to the project and rebuild. It starts to work as it should work, but this way is not as comfortable, especially if sources are on a remote machine and you need to configure .net back-end. Anyone knows how to solve?

    I am having an issue rendering images in flash via a character array. I am sending it from a webhandler via Context.Response.Write as a Base64CharacterArray. It functions 100% properly in a windows environment, however when using a Mac the image data is not retrieved correctly causing the image to appear incorrectly. It does not affect the data,however as it is rendered properly in a player which accesses the data via a webservice. I am at the end of my rope on this one. Anything will help. You can find an example at the following url http://www.discoverirelandtoday.com/photoalbum/Public/Main.aspx Thanks

  • Images saved with D3DXSaveSurfaceToFile will open in Paint, not Photoshop

    - by bsruth
    I'm using D3DXSaveSurfaceToFile to save windowed Direct3D 9 surfaces to PNG, BMP and JPG files. There are no errors returned from the D3DXSaveSurfaceToFile call and all files open fine in Windows Photo Viewer and Paint. But they will not open in a higher end image editing program such as Paint Shop Pro or Photoshop. The error messages from these programs basically say that the file is corrupted. If I open the files in Paint and then save them in the same file format with a different file name, then they'll open fine in the other programs. This leads me to believe that D3DXSaveSurfaceToFile is writing out non-standard versions of these file formats. Is there some way I can get this function to write out files that can be opened in programs like Photoshop without the intermediate step of resaving the files in Paint? Or is there another function I should be using that does a better job of saving a Direct3D surfaces to an image?

  • How to display the rss version of a News Link

    - by cbrown16
    I'm trying to write a script that will show the rss version of a single url (title, author, image, source, etc..). This should behave much the way that facebook does when you copy paste a link to share and it generates this information automatically. I'm trying to do this with a php script but would also be open to opensource programs that can do this as well. also, if anyone knows of any Joomla/Drupal plugins that can do this that would be great. This may eventually end up on a site run on one of these frameworks. thanks!!

  • MYSQL Event Scheduler DELIMITER using PHP

  • Scrolling a Div programatically using say Javascript

    - by SARAVAN
    Hi I have a jqgrid which is embedded in a Div. I am deleting records from the grid and reloading the grid using grid.Trigger('reload'). The width of the grid is considerably high so it has a scroll bar. Now I scrolled through the end of the grid horizontally before deleting records. Each time I delete the records and reload the grid, the column headers and their values are slightly misaligned. When I move the scroll bar back to original position or just move the scroll bar slightly they are aligned properly. So I thought its better to move the scroll bar to its inital position when the grid reloads. How can a scroll bar be programatically moved using javascript. Or is there any other way to solve my problem?

  • How to kill all subprocesses of shell?

    - by depesz
    I'm writing bash script, which does several thing. In the beginning it starts several monitor scripts, each of them runs some other tools. At the end of my main script, I would like to kill all things that spawned from my shell. So, it might looks like this: #!/bin/bash some_monitor1.sh & some_monitor2.sh & some_monitor3.sh & do_some_work ... kill_subprocesses The thing is that most of these monitors spawn their own subprocesses, so doing (for example): killall some_monitor1.sh will not always help. Any other way to handle this situation?
