    - by Thomas
    I have the following: public interface ICartItem { string Name { get; set; } } public class CartItem : ICartItem { public string Name { get; set; } } I then create a List and cast it to an interface: IList<CartItem> items = new List<CartItem>() { new CartItem() { Name = "MyItem" } }; IList<ICartItem> cartItems = items.Cast<ICartItem>().ToList(); Is there a way to cast it back again like illustrated below? IList<CartItem> newList = cartItems as IList<CartItem>;

  • Check if a variable is empty

    - by Thomas
    I have some user-submitted variables that I want to display in a different part of my site like this: <div class="pre_box">Term: </div> <div class="entry"><?php $key='term'; echo get_post_meta($post->ID, $key, true); ?></div> Occasionally, these variables might be empty in which case I don't want to display the label for the empty variable. In the example above I would want to hide the <div class="pre_box">Term: </div> part. Is there some simple way to check if a php variable like the one above is empty and prevent the label from being displayed?

  • Spring @Transactional Annotation Best Practice

    - by Thomas Einwaller
    We are currently discussing the Best Practice for placing the @Transactional annotations in our code. Do you place the @Transactional in the DAO classes and/or their methods or is it better to annotate the Service classed which are calling using the DAO objects? Or does it make sense to annotate both "layers"?

  • Jquery Slider PNG black borders IE8

    - by Thomas
    Greetings, I'm having a lot of trouble with the IE8 buy of getting black borders when using a JQUERY slider, with PNG transparent images. Using a slightly modified version of the Nivio slider. I have searched high and low for fixes and blocks of code but so far none have worked. What happens is that as soon as the img cycles it gets the black border and looks like shit (only in IE8). Does anyone know a working fix for this? Or do we just have to ban IE from all computers?

  • How to update a string property of an sqlite database item

    - by Thomas Joos
    hi all, I'm trying to write an application that checks if there is an active internet connection. If so it reads an xml and checks every 'lastupdated' item ( php generated string ). It compares it to the database items and if there is a new value, this particular item needs to be updated. My code seems to work ( compiles, no error messages, no failures, .. ) but I notice that the particular property does not change, it becomese (null). When I output the binded string value it returns the correct string value I want to update into the db.. Any idea what I'm doing wrong? const char *sql = "update myTable Set last_updated=? Where node_id =?"; sqlite3_stmt *statement; // Preparing a statement compiles the SQL query into a byte-code program in the SQLite library. // The third parameter is either the length of the SQL string or -1 to read up to the first null terminator. if (sqlite3_prepare_v2(database, sql, -1, &statement, NULL) == SQLITE_OK){ NSLog(@"last updated item: %@", [d lastupdated]); sqlite3_bind_text(statement, 1, [d lastupdated],-1,SQLITE_TRANSIENT); sqlite3_bind_int (statement, 2, [d node_id]); }else { NSLog(@"SQLite statement error!"); } if(SQLITE_DONE != sqlite3_step(statement)){ NSAssert1(0, @"Error while updating. '%s'", sqlite3_errmsg(database)); }else { NSLog(@"SQLite Update done!"); }

  • Dropdown not working in some IE 6 browsers

    - by James Thomas
    We unfortunately find ourselves having to support our product in IE 6 because some of our largest users use it. One of them called today and told me that one of the dropdowns doesn't work when he clicks on it - it simply selects the first item. I checked the markup and the entire contents of the select control are being sent: <select onchange="SDateFilter_S('#ctlDateRange')" size="1" name="ctlDateRange" style="width:100px;"> <option selected="selected" value="0"> All Dates </option><option value="1"> Within </option><option value="2"> Before </option><option value="3"> After </option><option value="4"> Between </option><option value="5"> Last </option><option value="6"> Since </option> </select> This is done in ASP .NET but I am fairly certain the issue isn't with ASP .NET as when I try it in my copy of IE 6, it works correctly. Do you have any idea what would cause a dropdown list in some copies of IE 6 to effectively not work?

  • Is there a way to do this with basic JS DOM?

    - by Thomas
    I need to apply/remove to an input field according to a user's selection in a separate drop down form - but I can't figure out how to target the input's class. I need to add/remove the 'pageRequired' class from this input: <input type="text" title="Company Required" name="customfields-tf-2-tf" class="inputclass pageRequired textInput" id="customfields-tf-2-tf" /> When the user selects one of two options from a drop down field. For example: <select class="dropdown" name="customfields-s-1-s" id="customfields-s-1-s" > <option value="Owner"<?php if(in_array("Owner",$temp_values)) { ?> selected='selected'<?php } ?>> Owner</option> <option value="Broker"<?php if(in_array("Broker",$temp_values)) { ?> selected='selected'<?php } ?>> Broker</option> </select> If the user selects broker than I want to add the pageRequired class to the first input field and remove it if the user selects Owner.

  • Mixing has_one and has_and_belongs_to_many associations

    - by Thomas
    I'm trying to build a database of urls(links). I have a Category model that has and belongs to many Links. Here's the migration I ran: class CreateLinksCategories < ActiveRecord::Migration def self.up create_table :links_categories, :id => false do |t| t.references :link t.references :category end end def self.down drop_table :links_categories end end Here's the Link model: class Link < ActiveRecord::Base validates :path, :presence => true, :format => { :with => /^(#{URI::regexp(%w(http https))})$|^$/ } validates :name, :presence => true has_one :category end Here's the category model: class Category < ActiveRecord::Base has_and_belongs_to_many :links end And here's the error the console kicked back when I tried to associate the first link with the first category: >>link = Link.first => #<Link id: 1, path: "http://www.yahoo.com", created_at: "2011-01-10... >>category = Category.first => #<category id : 1, name: "News Site", created_at: "2011-01-11... >>link.category << category => ActiveRecord::StatementInvalid: SQLite3::Exception: no such column : categories.link_id: Are my associations wrong or am I missing something in the database? I expected it to find the links_categories table. Any help is appreciated.

  • How to track dealloc of an abstract object class (NSMutable...)

    - by Thomas Tempelmann
    I have a bug in my code caused by a premature freeing of a ObjC object. I seem not to be able to find it by just looking at my code. There's usually a simple trick to track the dealloc to any class: Implement dealloc, and set a breakpoint. This even usually works with standard objects, by subclassing them and making sure I instantiate the subclass instead of the standard class. However, this does not seem to work with NSMutableArray, and probably neither with similar NSMutable... classes. Some explanations for this can be found here: link text Any other ideas how to track the dealloc invocation of a particular class or object so that I can see the call stack? It's probably possible with DTrace. Any pointers without having to read the entire dtrace docs first?

  • C++ integer floor function

    - by Thomas
    I want to implement greatest integer function. int x = 5/3; My question is with greater numbers could there be a loss of precision as 5/3 would produce a double? EDIT: Greatest integer function is integer less than or equal to X. Example: 4.5 = 4 4 = 4 3.2 = 3 3 = 3 What I want to know is 5/3 going to produce a double? Because if so I will have loss of precision when converting to int. Hope this makes sense. RE-EDIT: What OP calls 'greatest integer' most of us call 'floor'.

    - by Thomas
    In my website everybody can send some links to other nice websites. All links in my database must by unique, but some links are with 'www.' prefix, and some without. Some ends for '/', some not. For example: |http://www.domain.com |http://domain.com |http://domain.com |http://domain.com/ and other problems can be with https or http. I know that I should change address before saving to database, but what standard I should use?
