  • How to use pure in D 2.0

    - by James Dean
    While playing around with D 2.0 I found the following problem: Example 1: pure string[] run1() { string[] msg; msg ~= "Test"; msg ~= "this."; return msg; } This compiles and works as expected. When I try to wrap the string array in a class I find I can not get this to work: class TestPure { string[] msg; void addMsg( string s ) { msg ~= s; } }; pure TestPure run2() { TestPure t = new TestPure(); t.addMsg("Test"); t.addMsg("this."); return t; } This code will not compile because the addMsg function is impure. I can not make that function pure since it alters the TestPure object. Am i missing something? Or is this a limitation? The following does compile: pure TestPure run3() { TestPure t = new TestPure(); t.msg ~= "Test"; t.msg ~= "this."; return t; } Would the ~= operator not been implemented as a impure function of the msg array? How come the compiler does not complain about that in the run1 function?

  • Removing an array dimension where the elements sum to zero

    - by James
    Hi, I am assigning a 3D array, which contains some information for a number of different loadcases. Each row in the array defines a particular loadcase (of which there are 3) and I would like to remove the loadcase (i.e. the row) if ALL the elements of the row (in 3D) are equal to zero. The code I have at the moment is: Array = zeros(3,5) % Initialise array Numloadcases = 3; Array(:,:,1) = [10 10 10 10 10; 0 0 0 0 0; 0 0 0 0 0;]; % Expand to a 3D array Array(:,:,2) = [10 10 10 10 10; 0 0 0 0 0; 0 0 0 0 0;]; Array(:,:,3) = [10 10 10 10 10; 0 0 0 0 0; 0 0 20 0 0;]; Array(:,:,4) = [10 10 10 10 10; 0 0 0 0 0; 0 0 20 0 0;]; % I.e. the second row should be removed. for i = 1:Numloadcases if sum(Array(i,:,:)) == 0; Array(i,:,:) = [] end end At the moment, the for loop I have to remove the rows causes an indexing error, as the size of the array changes in the loop. Can anyone see a work around for this? Thanks

  • Sphinx non-fulltext, integer only search

    - by James
    Hello guys, I've got a few tables that literally only hold integers, no "words" and for some reason Sphinx is unable to hold this data in it's library. Just returns "0 bytes" errors for these indexes. Is it possible to do this? If so, how? Below is an example from my Sphinx.conf for one that fails. source track { type = mysql sql_host = host sql_user = user sql_pass = pass sql_db = db sql_port = port sql_query = SELECT id, user, time FROM track; sql_attr_uint = user sql_attr_uint = time sql_query_info = SELECT * FROM track WHERE id=$id } index track { source = track path = /var/lib/sphinx/track docinfo = extern charset_type = utf-8 min_prefix_len = 1 enable_star = 1 }

  • WebBrowser question

    - by James Jeffery
    I have a web page loaded into a WebBrowser object. What I want to do is access the elements on that page to input data. For example, enter username and password and submit the form. How is this possible? Any ideas? Could I use HTMLAgilityPack to access the elements and set their values?

  • A new method of supporting FOSS?

    - by James
    I have been kicking an idea around for sometime and wondered if something of it's nature hadn't already been invented. The premise is a website that integrates code management, project/team management, and micro-transactions. Donations, in and of themselves, are a sporadic, and unreliable method of supporting developers. Furthermore most free software that accepts donations is started by programmers ,be it to learn, because of a hobby, or because they saw a niche that needed to be filled. There is no method in place of of saying "hay, the FOSS community needs this kind of software, will someone develop it, and accept donations!?" Programmers should be programming, not busy begging for money. Basically the idea is people can go to the site in question, and start a project or make a request. Anyone signed up with the site can start a request. Each member account is free to support or "upvote" a project request. Requests and the associated number of votes let programmers in the community know the needs of the community. When a project is started a request for developers can be put forth. Developers have a ranking based on commits to other projects. The project founder can send invites to known Developers, or accept invites from members based on developer ranking. Once the project has at least one team-member, an objectives sheet or "draft" can be put out, listing design, goals, and features. The founding member and each team-member may contribute to this sheet. Each "milestone", or "Feature" is represented by an article. An article is any unit of a draft that can be voted on by The Project Founder, Team-members, and contributors...which brings me to the next half of this idea. --Microtransactions-- People signed up with this hypothetical website can purchase credits which then can be transfered to projects they would like to support. Anyone who transfers credits to a project is known as a contributor to that project. At anytime a Founder, or the lead team-member may submit an article, or a design (multiple articles) for consideration. All team-members, as well as the Founder, can vote once for each article freely. Contributors may vote yes or no on a number of articles (independent of any given meeting where a particular design or article is considered) equal to the number of credits they have placed into a contributors fund for that particular project. A contributors fund is a proxy between a sites credit account, and a projects credit account. It is sort of like a promise to contribute, instead of an actual contribution. Contributers may place constraints on particular articles such that if those constraints (a yes or no vote) are satisfied then a manually specified amount of credits is automatically transfered to the project account. This allows a project to develop based on the needs of those who may (in the future) financially rely on the project. --- Code commits & milestones --- When a team-member makes a commit, they may specify if it's a minor commit, a bug fix, a compatibility patch (i.e. for a new platform), or a milestone (an article voted on previously). People signed up with the website, may download the updated project and test it to see if the programmer's assertion is true about the commit. A report may then be filed on a small form, giving a one or two paragraphs, and a positive or negative confirmation of the programmer's goal for that particular commit. After all milestones for a particular draft are complete, a new draft is submitted for voting. Also funds may withdrawn by each team-member based on the proportion of commits and milestones confirmed (fulfilled the stated purpose) for each programmer. --- voting --- Members, contributor, and non-contributor, may make priority requests for particular articles of a draft. The project founder may or may not opt to fill those requests based on the volume of upvotes. A fulfilled priority request means that any team-member that makes a community-confirmed commit for an article is, when all articles for the draft are fulfilled, granted a portion of project credits in proportion to the average priority of all the articles he committed. ---- Notes --- While this is horribly prone to design-by-committee the one saving grace is that the lead team-member may place constraints on a draft such that some, or ALL articles must be voted yes. Commits may not begin until a draft satisfying said constraints is approved. What does SO think, is this idea feasible? Does anyone see major problems with this? Is there any insights, or improvements that could be made?

  • Ordering Wordpress posts by most recent comment

    - by James
    I'm wanting to order Wordpress posts by the most recent comment. To the best of my knowledge this isn't possible using the WP_Query object, and would require a custom $wpdb query, which I can easily write. However, I then don't know how to setup the loop to run off this object. Can anyone help?

  • Convert any currency string to double

    - by James
    I need to store multiple currencies in SQL server. I understand that SQL won't support all different types of currencies (unless I store it as a string, but I don't want to do that). My idea was to convert all the values from their currency format to a standard double and store that instead. Then just re-format based on the culture info when displaying. However, I have tried doing something like e.g. var cultureInfo = new System.Globalization.CultureInfo("en-US"); double plain = return Double.Parse("$20,000.00", cultureInfo); This doesn't ever seem to work it always throws a FormatException. Even removing the currency symbol and just trying to do this based on the number alone does the same thing. This is just an example I want to support pretty much any type of currency. Is there a standard way of stripping out currency and getting the value as a double?

  • How to make IE 9 Standards Mode the default mode?

    - by Evik James
    I have a web site that works perfectly fine in IE9 when compatibility mode is turned OFF (the compatibility symbol is gray). When compatibility mode is turned on (blue), the jQuery doesn't work at all. I have added the following tag to the site to tell the browser that compatibility mode should NOT be used. <meta http-equiv="X-UA-Compatible" content="IE=Edge" > I have the doctype as this: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Still, the browser doesn't seem to default to standard mode and the user must manually ensure that they are NOT in compatibility mode. Can I disable IE 9 Compatibility Mode? Have I done what I need to do to disable IE 9 Compatibility Mode? Can the user always override IE 9 Standards Mode?

  • Reformat a YouTube URL using jQuery

    - by jamEs
    I am using the YouTube Channel jQuery script to pull in data from a YouTube channel. Then I'm using an iFrame on the page to display the videos without leaving the site. The only problem is that the URLs the Channel plugin is pulling in don't quite work with my iFrame concept. They load the whole YouTube page instead of just the video. I figured out a workaround that basically I reformat the URL and tell it to display fullscreen and to autoplay will do what I would like it to do. The URLs are currently formatted like http://www.youtube.com/watch?v=xxxxxxxxx&feature=youtube_gdata and I need them to be rewritten as http://www.youtube.com/v/xxxxxxxxx?fs=1&autoplay=1 I've seen a couple of similar topics here on SO, but given my limited jQuery and regex talents I wasn't able to get anything to work for my purposes.

  • dojox.widget.dialog: disable close button opacity animation

    - by James Maroney
    I am nearly happy with my dialog widget now, only that there is a built-in behavior of the close button fading in and out with mouseover/out interaction. I have found no way to disable this feature such that the close button remains at full opacity anytime the dialog is open. Here's roughly the code I'm working from: var d = new dojox.widget.Dialog({modal:true,sizeMethod:"chain",closable:true}); d.startup(); d.attr('content', /*html content*/); d.attr('dimensions',[/*width*/, /*height*/ ]).show(); There's much logic that I'm omitting here for brevity, but this should be all that is specifically pertinent to the way I am constructing the dialog. Many Thanks.

  • Do any browsers yet support HTML5's checkValidity() method?

    - by James A. Rosen
    The HTML5 spec defines some very interesting validation components, including pattern (for validating against a Regexp) and required (for marking a field as required). As best I can tell, however, no browser yet actually does any validation based on these attributes. I found a comparison of HTML5 support across engines, but there is no information about validation there. In the browsers I've tried (Firefox 3.5.8 and Safari 4.0.4), no object has a checkValidity() method, so I can't run the validations even though I can define them. Is there any support for this feature out there so I can experiment?

  • How to display a date as iso 8601 format with PHP

    - by Matthew James Taylor
    I'm trying to display a datetime from my MySQL database as an iso 8601 formated string with PHP but it's coming out wrong. 17 Oct 2008 is coming out as: 1969-12-31T18:33:28-06:00 which is clearly not correct (the year should be 2008 not 1969) This is the code I'm using: <?= date("c", $post[3]) ?> $post[3] is the datetime (CURRENT_TIMESTAMP) from my MySQL database. Any ideas what's going wrong?

  • How do I get save (no exclamation point) semantics in an ActiveRecord transaction?

    - by James A. Rosen
    I have two models: Person and Address which I'd like to create in a transaction. That is, I want to try to create the Person and, if that succeeds, create the related Address. I would like to use save semantics (return true or false) rather than save! semantics (raise an ActiveRecord::StatementInvalid or not). This doesn't work because the user.save doesn't trigger a rollback on the transaction: class Person def save_with_address(address_options = {}) transaction do self.save address = Address.build(address_options) address.person = self address.save end end end (Changing the self.save call to an if self.save block around the rest doesn't help, because the Person save still succeeds even when the Address one fails.) And this doesn't work because it raises the ActiveRecord::StatementInvalid exception out of the transaction block without triggering an ActiveRecord::Rollback: class Person def save_with_address(address_options = {}) transaction do save! address = Address.build(address_options) address.person = self address.save! end end end The Rails documentation specifically warns against catching the ActiveRecord::StatementInvalid inside the transaction block. I guess my first question is: why isn't this transaction block... transacting on both saves?

  • Modify action names for route collections in Symfony?

    - by James Skidmore
    When creating an sfPropelRouteCollection, how can I edit the action names that the collection will generate? For example: # Routing for "product" CRUD product: class: sfPropelRouteCollection options: model: Product module: product actions: [new, create, edit, update, delete] How can I change the actual action that is called for any of the new/create/edit/update/delete methods? I'd like for them to call "ajaxNew," "ajaxCreate," etc. so the URL would look something like "product/ajaxNew", or the action for "update" would be "ajaxUpdate". Let me know if I need to clarify further. Thanks.

  • Reporting Services Matrix Order

    - by James Stewart
    I've got a reporting services report which display data in a matrix. The matrix rows are ordered by the report on a specific field's value. Trouble is I want a particular value to always appear last in the matrix even though it won't naturally be ordered there. Is there a way I can do this using an expression? Thanks.

  • Delphi App has "No Debug Info" when Debugging

    - by James L.
    We have built an application that uses packages and components. When we debug the application, the "Event Log" in the IDE often shows the our BPLs are being loaded without debug information ("No Debug Info"). This doesn't make sense because all our packages and EXEs are built with debug. _(each project) | Options | Compiling_ [ x ] Assertions [ x ] Debug information [ x ] Local symbols Symbol reference info = "Reference info" [ ] Use debug .dcus [ x ] Use imported data references _(each project) | Options | Linking_ [ x ] Debug information Map file = Detailed We have 4 projects, all built with runtime pacakges: Core.bpl Components.bpl Plugin.bpl (uses both #1 & #2) MainApp.exe (uses #1) Problems Observed 1) Many times when we debug, the Components.bpl is loaded with debug info, but all values in the "Local Variables" window are blank. If you hover your mouse over a variable in the code, there is no popup, and Evaluate window also shows nothing (the "Result" pane is always blank). 2) Sometimes the Event Log shows "No Debug Info" for various BPLs. For instance, if we activate the Plugin.bpl project and set it's Run | Parameter's Host Application to be the MainApp.exe, and then press F9, all modules seems to load with "Has Debug Info" except for the Plugin.bpl module. When it loads, the Event Log shows "No Debug Info". However, if we close the app and immediately press F9, it will run it again without recompiling anything and this time Plugin.bpl is loaded with debug ("Has Debug Info"). Questions 1) What would cause the "Local Variables" window to not display the values? 2) Why are BPLs sometimes loaded without debug info when the BPL was complied with debug and all the debug files (dcu, map, etc.) are available?

  • Is it possible to use ASP.NET Dynamic Data and SubSonic 3?

    - by James
    Is it possible to use ASP.NET Dynamic Data with SubSonic 3 in-place of Linq to SQL classes or the Entity Framework? MetaModel.RegisterContext() throws an exception if you use the context class that SubSonic generates. I thought I remembered coming across a SubSonic/Dynamic Data example back before SubSonic 3 was released but I can't find it now. Has anyone been able to get this to work?

  • Can checkboxes be removed from a .NET WinForms ListView at runtime?

    - by James
    Is it possible to remove the checkboxes from a .NET WinForms ListView control at runtime? The following code appears to have no effect when '.Checkboxes' has initially been set to 'true' and the control has rendered onto a form with checkboxes available for each list view item: // C#: testListView.BeginUpdate(); testListView.Checkboxes = false; testListView.EndUpdate(); Is there a method that must be called to enact this change? What is the use of providing the .Checkboxes property when it defaults to 'false' and only has an effect if set to 'true'?

  • jQuery issue with anchor tag using jqTransform

    - by James Helms
    I'm using jqtransform on my site. When the user is on a for them to be able to use hot keys to move through the selections. I added this function: $wrapper.find('a').keydown(function (e) { var Esc = 27; var code = (e.keyCode ? e.keyCode : e.which); if(code== Esc || (code>=65 &&code<=90)){ var letter = String.fromCharCode(code); if (code==Esc) keyCodes = ""; else{ if (keyCodes=='') keyCodes += letter; else keyCodes += letter.toLowerCase(); var item = $wrapper.find('a[text^=\'' + keyCodes + '\']:first'); item.click(); } } }); inside of $.fn.jqTransSelect. This code works fine in all browsers but IE. the only thing i can find is that IE doesn't like the click event. Can anyone please help me with this? If i debug into the code I can see that item is a select not an anchor like i would expect it to be, and that confuses me even more.
