  • CKEDITOR, is return some strange characters

    - by nobosh
    With CKEDITOR, when I use JS to get the contents of the Text Editor, I'm getting back: <p>\u000a\u0009&nbsp;ad adad ad asd</p>\u000a When I should have gotten: <p>ad adad ad asd</p> Any idea what's going on here? The only difference that could be the cause is that I'm dynamically created textareas on load, and using a class to find the editor: $('.guideItem-textarea').each(function(index, value){ // ID of the textarea var targeteditor = $(this).attr('id'); var targeteditorID = $(this).attr('id').replace('noteguide',''); // Contents in the editor textareacontents = CKEDITOR.instances[targeteditor].getData(); }); Any ideas?

  • Dynamic resize with MPlayer and PyGTK

    - by alex
    Hi everyone; I've wrote a piece of code in python and pygtk for an embeded mplayer in a gui. I assume I use GtkSocket and the slave mode of mplayer with the -wid option. But I've got an issue, when the size of my GTK window is smaller than my stream, the stream appears to be cropped. And when the size of my window is bigger than my stream, the stream appear centred inside the widget which embed MPlayer. (a gtk.Frame but I've also try with a gtk.DrawingArea) I would like to know how I can get my stream resize dynamically depending on the window's size. I don't want to use Glade or any GUI builder. Thanks in advance for any help, and please excuse my poor english.

  • How can I request local pages in the background of an ASP.NET MVC app?

    - by flipdoubt
    My ASP.NET MVC app needs to run a set of tasks at startup and in the background at a regular interval. I have implemented each task as a controller action and listed the app-relative path to the action in the database. I implemented a TaskRunner process that gets the urls from the database and requests each one at a regular interval using WebRequest.Create, but this throws a UriFormatException. I cannot use this answer or any code that plucks values from HttpContext.Current.Request without getting an HttpException with the message "Request is not available in this context". The Request object is not available because my code uses System.Threading.Timer to do background processing, as recommended here. Here are my questions: Is there really no way to make local web requests within an ASP.NET web app? Is there really no way to dynamically ascertain the root path to the web app even using static dependencies in ASP.NET? I was trying to avoid storing the app's root path in the database (as FogBugz does with its "Maintenance Path"), but is this best option?

  • Can I use AppDomain.AssemblyResolve Event to redirect a failed Assembly Load?

    - by esac
    By default, my application references a mixed mode DLL, so this DLL is both 32 and 64 bit. On a 32 bit system, my app is MSIL and loads the 32 bit DLL. On a 64 bit system, my app loads the 64 bit. However on a 64 bit system, in an older version of the assembly that I am referencing, they only created a 32 bit version. So I fail to load this. I was looking at doing it dynamically, and ideally I would want my MSIL app in 64 bit mode to load the 32 bit DLL. Is this possible? Also it would be nice to resolve it to a different version than what I have referenced as well. Any help appreciated.

  • how to add a meta tag to the page template from Wordpress plugin?

    - by detj
    I want to add a meta tag like this one: <meta name="key" content="value" /> to some of the pages in Wordpress. I know, I can add this into my template and it will show up. But the thing is, I am not allowed to even touch the template. It's totally template independent. So, I have to add the meta tag only by doing something in my plugin code. I have tried wp_head action hook, but it is not working. Any idea of a workaround or anything to get the meta tag inside the head tags of the pages dynamically.

  • Set database based on how the application was started

    - by AaronThomson
    I have two Rails applications (lets call them APP-1 and APP-2), each of them has a dependancy on a third Rails application (APP-3). I would like to be able to run the tests for APP-1 and APP-2 in parallel on my CI server. The problem is, both need to start up APP-3 and write to a DB via the APP-3. This causes conflicts and failures if the tests are run in parallel. My idea for a solution is for APP-1 and APP-2 to each start their own instance of APP-3 and to have each instance point to a different DB. Is there a way to dynamically set the DB in the database.yml of APP-3 so that it connects to a different DB depending on which APP starts it up? FYI. APP-1 and APP-2 currently start APP-3 via rake tasks.

  • ASP.NET MVC2 - specific fields in form pass via a specific object?

    - by ile
    In database I have Contacts table: ContactID (int) FirstName (varchar) LastName (varchar) ... XmlFields (xml) // This field is xml type To create a new contact, I created two classes - one for regular fields and other to display fields from XmlFields field. In Controller, I have following: public ActionResult Create(Contact contact, FormCollection collection) ... Regular field I catch with contact object and those that need to be stored as xml in XmlFields I try to catch with collection object. Problem is that collection object catches all fields, so I wonder if it is possible to isolate xml fields when posting to a specific object so that I can easily manipulate with them. I need this in separated objects because these xml fields are going to be generated dynamically and will be different for every user. Thanks in advance, Ile

    - by pfunc
    I am creating a nav in flex that pulls in buttons dynamically from xml. THe problem i am having is setting the button width to the text width. currently the buttons are all the same width and if the text is larger then it just cuts off. I've tried a few ways of doing this: Setting button width to 100% On creation of the button try to set the width of the button to the text programmatically. Something like evt.target.width = evt.target.textWidth; Anyone know the correct way to do this?

  • Find value of selected item in Drop down menu.

    - by Ozaki
    I have a drop down menu in an ASPX page along the lines of: <form> <select name="cars"> <option value="volvo">Volvo</option> <option value="saab">Saab</option> <option value="fiat" selected="selected">Fiat</option> <option value="audi">Audi</option> </select> </form> That is dynamically generated from another controller (value and label). After the user selects one of the options I need to find out what the selected value/label (will be the same) is so I can hit an update button and retrieve the data on that option. What would be the easiest way to find out the value of the user "selected" option?

  • Closing any open info windows in google maps api v3

    - by hhj
    As the title states, on a given event (for me this happens to be upon opening a new google.maps.InfoWindow I want to be able to close any other currently open info windows. Right now, I can open many at a time..but I want only 1 open at a time. I am creating the info windows dynamically (i.e. I don't know ahead of time how many will be generated), so in the click event of the current info window (which is where I want all the other open ones closed) I don't have a reference to any of the other open info windows on which to call close(). I am wondering how I can achieve this. I am not an experienced JavaScript programmer so I don't know if I need to use reflection or something similar here. Would the best way be just to save all the references in some sort of collection, then loop through the list closing them all? Thanks.

  • Multiple children in single form in rails

    - by CaptnCraig
    I have a model that has an arbitrary number of children entities. For simplicity lets call the entities Orders and Items. I would like to have a create Orders form where I input the order information, as well as add as many items as I want. If I click the "Add another item" button, a new set of form elements will be added to input the new data, amounts, etc.. I could hack this out in pure javascript, but I'm pretty sure there has to be a more magical, railsish way to do it, maybe with a partial view or something. I'm just a little too new to rails to know what it is. What is the best way to dynamically add the new form elements, and then to access them in the create controller?

  • How can I access form elements when using an ASP.NET MVC Ajax form?

    - by Patrick
    I've got an ajax form in an MVC 2 application. I cannot find the proper way to access the form elements within the Ajax form decleration. I can access the name of the elements with Request.Form.Keys but I can't access the actual values. I've read numerous examples of posting forms with jQuery but my form has elements created dynamically based on route values (sometimes it could be 2 text boxes sometimes 10, given unique names like so: <%= Html.TextBox("Evaluation"+Model.EvaluationId.ToString())) so I couldn't find a way to make that work with jQuery. Is there another way that I for elements can be accessed?

  • adding numeric values of variable number of forms

    - by user306472
    I'm trying to use jquery to loop through a block of forms that contain numeric data and add it all up to be displayed in a form with id grand. I have the ability to dynamically add new forms, so the number of forms I'm looping through will change. Here's my jquery code I wrote that isn't working for whatever reason: $('#table').delegate('input#grand', 'focus', function(){ var grand = $(input.expend).map(function(){ return this.value; }); $(grand).each(function(){ var g = 0; g+= $(this); $('input#grand').val(g); }); });

  • Rails Metaprogramming: How to add instance methods at runtime?

    - by Larry K
    I'm defining my own AR class in Rails that will include dynamically created instance methods for user fields 0-9. The user fields are not stored in the db directly, they'll be serialized together since they'll be used infrequently. Is the following the best way to do this? Alternatives? Where should the start up code for adding the methods be called from? class Info < ActiveRecord::Base end # called from an init file to add the instance methods parts = [] (0..9).each do |i| parts.push "def user_field_#{i}" # def user_field_0 parts.push "get_user_fields && @user_fields[#{i}]" parts.push "end" end Info.class_eval parts.join

  • rails code within javascript

    - by Jesse
    I am trying to use some rails code withing a javascript and need to have that rails code be dynamically changed. Here's the line of code: $(this).replaceWith("<%= escape_javascript(render(:partial => 'shared/products')) %>"); The 'shared/products' is the part I want to change based off information passed earlier in the javascript. How do I insert a value from javascript so that instead of 'shared/products' the products portion can be a variable? Hope this makes sense. I'm not the most experienced jQuery/javascript programmer, so any help is very much appreciated. Thanks in advance!

  • In MVVM are DataTemplates considered Views as UserControls are Views?

    - by Edward Tanguay
    In MVVM, every View has a ViewModel. A View I understand to be a Window, Page or UserControl to which you can attach a ViewModel from which the view gets its data. But a DataTemplate can also render a ViewModel's data. So I understand a DataTemplate to be another "View", but there seem to be differences, e.g. Windows, Pages, and UserControls can define their own .dlls, one type is bound with DataContect the other through attaching a template so that Windows, Pages, UserControls can can be attached to ViewModels dynamically by a ServiceLocator/Container, etc. How else are DataTemplates different than Windows/Pages/UserControls when it comes to rendering a ViewModel's data on the UI? And are there other types of "Views" other than these four?

  • When is it appropriate to use C++ exceptions?

    - by krebstar
    I'm trying to design a class that needs to dynamically allocate some memory.. I had planned to allocate the memory it needs during construction, but how do I handle failed memory allocations? Should I throw an exception? I read somewhere that exceptions should only be used for "exceptional" cases, and running out of memory doesn't seem like an exceptional case to me.. Should I allocate memory in a separate initialization routine instead and check for failures and then destroy the class instance gracefully? Or should I use exceptions instead? The class won't have anything useful to do if these memory allocations should fail.. EDIT: The consensus seems to be that running out of memory IS an exceptional case. Will see how to go about this.. Thanks.. :)

  • How can Excel 2007 / 2010 consume a REST web service?

    - by jallen
    What options exist to consume a REST web service from within Excel 2007 / 2010? I can use XML Maps to consume a basic XML list, but that doesn't let me build a dynamic URL (so I could include parameters). For example, I can add an XML Map to Excel for http://machine/service/level/5 and display the values in the workbook just fine - no problem there. The real question is, how can I dynamically change the /5 part of the URL to come from another cell in excel? That way I can have a couple of cells that have the options (what ID, what name, etc.) and whenever those values change (ideally) a new dynamic URL would be constructed and the XML map would be refreshed. Is such a thing possible? Does anyone else have a better way to take some parameters, call a web service (REST or SOAP, I'm not picky) and shove the results back into excel for further manipulation?

  • GWT application not displaying data on Windows 7 Starter Edition

    - by Steve Buikhuizen
    I have a GWT application that works great on all platforms/browsers etc. Then we tried Windows 7 Starter Edition. For all browsers (Chrome, IE, Firefox) none of the dynamically displayed data appears in the application. We know that the machine is ok because Google Wave works fine and its also a GWT application. I'm at a loss. What could cause this to happen? I'd be grateful if you have a suggestion as to how to debug this. If so find the solution I'll post it.

  • Get a CSS value from external style sheet with Javascript/jQuery

    - by Acorn
    Is it possible to get a value from the external CSS of a page if the element that the style refers to has not been generated yet? (the element is to be generated dynamically). The jQuery method I've seen is $('element').css('property','value');, but this relies on element being on the page. Is there a way of finding out what the property is set to within the CSS rather than the computed style of an element? Will I have to do something ugly like add a hidden copy of the element to my page so that I can access its style attributes?

  • Capture KeyUp event on form when child control has focus

    - by Jon B
    I need to capture the KeyUp event in my form (to toggle a "full screen mode"). Here's what I'm doing: protected override void OnKeyUp(KeyEventArgs e) { base.OnKeyUp(e); if (e.KeyCode == Keys.F12) this.ToggleFullScreen(); } private void ToggleFullScreen() { // Snazzy code goes here } This works fine, unless a control on the form has focus. In that case, I don't get the event at all (also tried OnKeyDown - no luck there either). I could handle the KeyUp event from the child control, but the controls on the form are generated dynamically, and there may be many of them - each having many children of their own. Is there any way to do this without generating event handlers for every control on the screen (which I certainly could do with a recursive function)?

  • PHP Included files writing their own content from Importer values ...

    Hello, I have a index.php file that will include several external files: "content/templates/id1/template.php" "content/templates/id2/template.php" "content/templates/id3/template.php" etc. All these files are loaded dynamically into index.php (it reads all folders inside "templates" directory and then includes every "template.php" file). I want to make "template.php" to have the same code in all the "id1,id2,id3" folders, BUT to load values from index.php depending in which folder it stays.. How can I do that? Thank You!

  • CheckBox gets converted to Button in Flex

    - by Ravz
    Hi, I am new to Flex, so please bear with me. I have encountered a strange problem. There's a ActionScript class which dynamically creates basic UI element. So I create RadioButton as var rBtn:RadioButton = new RadioButton(); and then put it in a Panel Container. The problem is that it appears to be a Button. However it behaves like RadioButton. I have found this problem with one more guy who has posted it here. CheckBoxes and RadioButton looks like Push Buttons. Please help me out with this. Thanks.
