  • Equality and Assigment Operators

    - by Jeremy Smith
    I have a assembly compiled in VB.NET that contains two operators: Public Shared Operator =(quarterA As CalendarQuarter, quarterB As CalendarQuarter) As Boolean Return quarterA.StartDate = quarterB.StartDate AndAlso quarterA.EndDate = quarterB.EndDate AndAlso quarterA.Quarter = quarterB.Quarter End Operator Public Shared Operator <>(quarterA As CalendarQuarter, quarterB As CalendarQuarter) As Boolean Return Not (quarterA = quarterB) End Operator However, when using the assembly in C# to perform equality checks if (qtr != null) I receive the error: Cannot implicity convert type 'object' to 'bool' My original intent with the = operator was only for assignment purposes in VB, so I may be way off base (I don't use custom operators too often). What do I need to do to make the operator behave with both equality and assignment operations?

  • Creating a list of most popular posts of the past week - Wordpress

    - by Gary Woods
    I have created a widget for my Wordpress platform that displays the most popular posts of the week. However, there is an issue with it. It counts the most popular posts from Monday, not the past 7 days. For instance, this means that on Tuesday, it will only include posts from Tuesday and Monday. Here is my widget code: <?php class PopularWidget extends WP_Widget { function PopularWidget(){ $widget_ops = array('description' => 'Displays Popular Posts'); $control_ops = array('width' => 400, 'height' => 300); parent::WP_Widget(false,$name='ET Popular Widget',$widget_ops,$control_ops); } /* Displays the Widget in the front-end */ function widget($args, $instance){ extract($args); $title = apply_filters('widget_title', empty($instance['title']) ? 'Popular This Week' : $instance['title']); $postsNum = empty($instance['postsNum']) ? '' : $instance['postsNum']; $show_thisweek = isset($instance['thisweek']) ? (bool) $instance['thisweek'] : false; echo $before_widget; if ( $title ) echo $before_title . $title . $after_title; ?> <?php $additional_query = $show_thisweek ? '&year=' . date('Y') . '&w=' . date('W') : ''; query_posts( 'post_type=post&posts_per_page='.$postsNum.'&orderby=comment_count&order=DESC' . $additional_query ); ?> <div class="widget-aligned"> <h3 class="box-title">Popular Articles</h3> <div class="blog-entry"> <ol> <?php if (have_posts()) : while (have_posts()) : the_post(); ?> <li><h4 class="title"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h4></li> <?php endwhile; endif; wp_reset_query(); ?> </ol> </div> </div> <!-- end widget-aligned --> <div style="clear:both;"></div> <?php echo $after_widget; } /*Saves the settings. */ function update($new_instance, $old_instance){ $instance = $old_instance; $instance['title'] = stripslashes($new_instance['title']); $instance['postsNum'] = stripslashes($new_instance['postsNum']); $instance['thisweek'] = 0; if ( isset($new_instance['thisweek']) ) $instance['thisweek'] = 1; return $instance; } /*Creates the form for the widget in the back-end. */ function form($instance){ //Defaults $instance = wp_parse_args( (array) $instance, array('title'=>'Popular Posts', 'postsNum'=>'','thisweek'=>false) ); $title = htmlspecialchars($instance['title']); $postsNum = htmlspecialchars($instance['postsNum']); # Title echo '<p><label for="' . $this->get_field_id('title') .

  • VB listbox cannot be indexed because it has no default value

    - by Shane Fagan
    I have a listbox and I want to loop through each of the items to see if the string im looking for is inside. I know I could do .contains but that wouldnt look at substrings. The code im using looks like this: While tempInt > Listbox.items.count then if searchString.contains(listbox(tempInt)) then end if tempInt+=1 end while Everything in the loop is fine but VB gives an error on the listbox(tempInt) part. The error is "class windows.forms.listbox cannot be indexed because it has no default value". Can anyone help get around the default value crap? I tried putting in a blank string but no change.

  • Re-using unit tests for models using STI

    - by TenJack
    I have a number of models that use STI and I would like to use the same unit test to test each model. For example, I have: class RegularList < List class OtherList < List class ListTest < ActiveSupport::TestCase fixtures :lists def test_word_count list = lists(:regular_list) assert_equal(0, list.count) end end How would I go about using the test_word_count test for the OtherList model. The test is much longer so I would rather not have to retype it for each model. Thanks.

  • read/write_attribure on associations

    - by artemave
    read/write_attribute is a great way to enhance default accessors generated by ActiveRecord. Like this for example: def price read_attribute(:price) or "This item is priceless and you are by the way #{User.current.login}" end The same however does not seem to be working with associations. Demonstration: class Product < ActiveRecord::Base has_and_belongs_to_many :stores end Then >> a = Product.first => #<Product id: 1, name: "awesome product", created_at: "2010-05-07 12:11:00", updated_at: "2010-05-07 12:11:00"> >> a.stores => [#<Store id: 1, name: "ikea", created_at: "2010-05-07 12:11:28", updated_at: "2010-05-07 12:11:28">] >> a.read_attribute(:stores) => nil >> So, is there some sort of read/write_association? Or, if not, is there a reason not to have one?

  • How can I stub out a call to super in a imported Java class in JRuby for testing

    - by Doug Chew
    I am testing Java classes with RSpec and JRuby. How can I stub out a call to super in an imported Java class in my RSpec test? For example: I have 2 Java classes: public class A{ public String foo() { return "bar"; } } public class B extends A public String foo() { // B code return super.foo(); } } I am just trying to test the code in B.foo and not the code in A.foo with JRuby. How can I stub out the call to the super class method in my RSpec test? rspec test: java_import Java::B describe B do it "should not call A.foo" do # some code to stub out A.foo b = B.new b.foo.should_not == "bar" end end I have tried including a module with a new foo method in B's class hoping that it would hit the module method first but B still makes a call to A. The inserting module technique works in Ruby but not with JRuby and imported Java classes. Any other ideas to stub out the superclass method to get my RSpec test to pass?

  • Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error.

    I get the following error in Chrome every time I try to run my script on a Linux server: Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error. In Firefox it just shows a blank white page.

  • How to add custom hooks to controllers in ASP.NET MVC2

    - by Adrian
    Hi, I've just started a new project in ASP.net 4.0 with MVC 2. What I need to be able to do is have a custom hook at the start and end of each action of the controller. e.g. public void Index() { *** call to the start custom hook to externalfile.cs (is empty so does nothing) ViewData["welcomeMessage"] = "Hello World"; *** call to the end custom hook to externalfile.cs (changes "Hello World!" to "Hi World") return View(); } The View then see welcomeMessage as "Hi World" after being changed in the custom hook. The custom hook would need to be in an external file and not change the "core" compiled code. This causes a problem as with my limited knowledge ASP.net MVC has to be compiled. Does anyone have any advice on how this can be achieved? Thanks

  • Using Excel VBA to send emails. Problem with attachments becoming embedded by accident.

    - by Alexei
    Hi, I am having an issue with an Excel macro I wrote that is used by several users within my company. It is used to send numerous emails daily with attachments that are also Excel workbooks. The issue is that sometimes, instead of the file simply being attached as it should be, it becomes an embedded object. This embedded object is openable by users on the email within the company (after clicking through the "YOu are about to activate an embedded object that may contain viruses or be otherwise harmful to your computer. It is important to be certain that it is from a trustworthy source. Do you want to continue?"), but those outside of the company do not see it at all. The email appears to have no attachment at all. Curiously, this appears to happen randomly, and only on some computers. So if the list has 15 email lists and attachments, it seems to happen randomly to anywhere between 0 and 15 of the emails. To be clear, my objective is to send emails with regular attachments. Running Excel 2003, Outlook 2003, and Windows XP. See code below. Please help! Sub Email() Dim P As String Dim N As String Dim M As String Dim Subject As String Dim Addresses As String Dim olApp As Outlook.Application Dim olNewMail As Outlook.MailItem Application.DisplayAlerts = False M = ActiveWorkbook.Name For c = 2 To 64000 If Range("B" & c) = "" Then Exit For If UCase(Range("E" & c)) = "Y" Then Workbooks(M).Sheets("Main").Activate Subject = Range("A" & c) Addresses = Range("B" & c) P = Range("C" & c) N = Range("D" & c) If Right(P, 1) <> "\" Then P = P & "\" If Right(N, 4) <> ".xls" Then N = N & ".xls" Set olApp = New Outlook.Application Set olNewMail = olApp.CreateItem(olMailItem) With olNewMail .Display .Recipients.Add Addresses Application.Wait (Now + TimeValue("0:00:01")) SendKeys ("{TAB}") .Subject = Subject .Attachments.Add P + N .Send End With Set olNewMail = Nothing Set olApp = Nothing End If Next c Range("E2:E65536").ClearContents Application.DisplayAlerts = True End Sub

  • .htaccess mod_rewrite issue

    - by Orhan Toy
    Almost in any project I work on, some issues with .htaccess occur. I usually just find the easiest solution and leave it because I don't have any knowledge or understanding for Apache, servers etc. But this time I thought I would ask you guys. This is the files and folders in my (simplified) setup: /modrewrite-test .htaccess /config /inc /lib /public_html .htaccess /cms /navigation index.php edit.php /pages index.php edit.php login.php page.php The "config", "inc" and "lib" folders are meant to be "hidden" from the root of the website. I try to accomplish this by making a .htaccess-file in the root that redirects the user to "public_html". The .htacess-file contains this: RewriteEngine On RewriteRule (.*) public_html/$1 This works perfect. If I type "http://localhost/modrewrite-test/login.php" in my browser, I end up in public_html/login.php which is my intention. So this works fine. The .htaccess-file in "public_html" contains this: RewriteEngine On # Root RewriteRule ^$ page.php [L] # Login RewriteRule ^(admin)|(login)\/?$ login.php [L] # Page (if not a file/directory) RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ page.php?url=$1 [L] The first rewrite just redirects me to public_html/page.php if I try to reach "http://localhost/modrewrite-test/". The next rewrite is just for the convenience of users trying to log in - so if they try to reach "http://localhost/modrewrite-test/admin" or "http://localhost/modrewrite-test/login" they will end up at the login.php-file. The third and last rewrite handles the rest of the requests. If I try to reach "http://localhost/modrewrite-test/bla/bla/bla" it will just redirect me to public_html/page.php (with the 'url' GET-variable set) instead of finding a folder called "la", containing a folder named "bla" and etc. All of these things work perfect but a minor issues occurs when I for instance try to reach "http://localhost/modrewrite-test/cms/navigation" without a slash at the end of the URL. When I try to reach that page the browser is somehow redirected to "http://localhost/modrewrite-test/public_html/cms/navigation/". The correct page is shown but why does it get redirected and add the "public_html" part in the URL? The desired behavior is that the URL stays intact and that the page public_html/cms/navigation/index.php is shown. The files and folders in the (simplified) can be found at http://highbars.com/modrewrite-test.zip

  • Rails equivalent of respond_to |format| with a straight render

    - by brad
    I'm working with ActiveResource a lot so my service models are only using XML. Thus, I have no need for a respond_to block, I literally just render :xml => @model I can't however figure out how to render a 404 header using this. I've had to resort to respond_to, which I think adds a few unnecessary method calls. Here's what I'm using: respond_to do |format| if (record_found) render :xml => @some_record else format.xml{ head :not_found } end end but I just want something like render :xml => head :not_found which doesn't work. Can anyone tell me the proper syntax?

  • Assert parameters in a table-valued UDF

    - by Clay Lenhart
    Is there a way to create "asserts" on the parameters of a table-valued UDF. I'd like to use a table-valued UDF for performance reasons, however I know that certain parameter combinations (like start and end dates that are more than a month apart) will cause performance issues on the server for all users. End users query the database via Excel using UDFs. UDFs (and table-valued UDFs in particular) are useful when the data is too large for Excel. Users write simple SQL queries that categorizes the data into groups to reduce the number of rows. For example, the user may be interested in weekly aggregates rather than hourly ones. Users write a group by SELECT statement to reduce the rows by 24x7=168 times. I know I can write RAISERROR statements in multistatement UDFs, but table-valued UDFs are integrated in the query optimizer so these queries are more efficient with table-valued UDFs. So, can I define assertions on the parameters passed to a table-valued UDF?

Some of the tables are fed by form submissions from users on the front end of the website. Some of the tables are purely in the CMS and are used to create custom modules on the front end of the website. Although there is a forms module in Drupal, I think our requirements cannot be met by it. Does anyone know of a system that allows forms to be saved to a CRUD style database with the following features? Export of all database fields. View a summary of the records in a filterable table. With paging You can have one to many relationships in records eg To code this manually for 10 forms is A LOT of work. Particularly the one to many relationships. If there is a powerful module available it would save us writing one.

  • Is there a Java equivalent to libevent?

    - by JoelPM
    I've written a high-throughput server that handles each request in its own thread. For requests coming in it is occasionally necessary to do RPCs to one or more back-ends. These back-end RPCs are handled by a separate queue and thread-pool, which provides some bounding on the number of threads created and the maximum number of connections to the back-end (it does some caching to reuse clients and save the overhead of constantly creating connections). Having done all this, though, I'm beginning to think an event-based architecture would be more efficient. In searching around I haven't found any equivalents to libevent for Java, but maybe I'm not looking in the right place? Mina-statemachine from Apache was the closest thing I found, but it looks more verbose than I need and there's no real release available. Any suggestions?

  • Clearing "may not respond" warnings for UIView and UIViewController

    - by user284681
    In an iPad app, I'm using a custom subclass of UIView with UIViewController. Here's the view header: @interface pdfView : UIView { CGPDFDocumentRef doc; } -(void)setDoc:(CGPDFDocumentRef)newDoc; @end And here's the controller header: @interface iPadPDFTestViewController : UIViewController { CGPDFDocumentRef doc; } - (void)loadPDF; @end Part of the controller implementation: - (void)viewDidLoad { [super viewDidLoad]; [self loadPDF]; [self.view setDoc:doc]; } In Interface Builder, I've set the view object to use the class pdfView. At compilation, [self.view setDoc:doc]; gives the warning "'UIView' may not respond to '--setDoc'." I'm guessing that this warning appears because the compiler thinks it's looking at UIView (which does not implement the setDoc method) instead of pdfView. But why does it think that? And how can I tell it what class it's really looking at, so as to clear the warning?

  • How to define one-to-many connection between a same model through another model

    - by Mekajiki
    I want to define one-to-many relationship as follows; User has one introducer User has many newcomers(who is introduced by the user) Use "Introduction" model instead of adding a column to users table. My table and model definition is as follows; DB Scheme: create_table "introductions", force: true do |t| t.integer "introducer_id" t.integer "newcomer_id" t.datetime "created_at" t.datetime "updated_at" User model: class User < ActiveRecord::Base has_many :introductions, foreign_key: :introducer_id has_many :newcomers, through: :introductions, source: :newcomer belongs_to :introduction, foreign_key: :newcomer_id belongs_to :introducer end Introduction model: class Introduction < ActiveRecord::Base belongs_to :introducer, class_name: 'User' belongs_to :newcomer, class_name: 'User' end This works fine: user1.newcomers.push user2 but, user2.introducer # => nil How can I define belongs_to relationship correctly?
