  • Custom Validator and specifying type of message

    - by user102533
    I have a custom validation in the enterprise validation block. The DoValidate method is as shown below. protected override void DoValidate(Double objectToValidate, object currentTarget, string key, ValidationResults validationResults) { if (!IsSalMoreThanMinWage(objectToValidate)) { //Here I need to mark this message as a "Warning" LogValidationResult(validationResults, "Salary is too low for this state", currentTarget, key); } } I'd need to mark this validation failure as a "warning" message. In the front end, when I iterate through the ValidationResults collection and grab a ValidationResult object, I would need to identify and group different types of messages and render them differently. My question is - how do I mark a failure as a warning?

  • System.Drawing - bad text rendering using DrawString on top of transparent pixels.

    - by mackenir
    When rendering text into a bitmap, I find that text looks very bad when rendered on top of an area with non-opaque alpha. The problem is progressively worse as the underlying pixels become more transparent. If I had to guess I'd say that when underlying pixels are transparent, the text renderer draws any anti-aliased 'gray' pixels as solid black. Here are some screenshots: Text drawn on top of transparent pixels: Text drawn on top of semi-transparent pixels: Text drawn on opaque pixels: Here is the code used to render the text: g.SmoothingMode = SmoothingMode.HighQuality; g.DrawString("Press the spacebar", Font, Brushes.Black, textLeft, textTop);

  • Pull image of rendered HTML from a specific browser

    - by Geo Ego
    I am working on an app that will be able to pull an image of rendered HTML from a specific browser. I would like the user to be able to select a specific browser to render an HTML file in, and capture the rendered output in an image file. I am starting with IE8, and I'm not sure where to begin to get the actual rendered output. I can easily open the file in that browser with Process.Start(), but I don't know how to return the rendered output. I have looked a little bit at sinking events, but I don't understand how that works or if that's the right way to go. I would just like some direction, and perhaps some resources to send me on the right path.

  • Rails: redirect_to :controller=>'tips', :action => 'show', :id => @tip.permalink

    - by john
    hi, I tried to redirect rails to show action by passing controller, action, and params. However, rails ignores the name of action totally! what I got is http://mysite/controllername/paramId so i have error message.... here is the action code I used: def update @tip = current_user.tips.find(params[:id]) @tip.attributes = params[:tip] @tip.category_ids = params[:categories] @tip.tag_with(params[:tags]) if params[:tags] if @tip.save flash[:notice] = 'Tip was successfully updated.' redirect_to :controller=>'tips', :action => 'show', :id => @tip.permalink else render :action => 'edit' end end

  • Creating records using RJS in rails

    - by Elliot
    Hey Everyone, so I've watched http://railscasts.com/episodes/43-ajax-with-rjs but I have a question: In my view I have the following: <div id="testly"> <%= render :partial => "test" %> </div> This works. Using create.rjs to change the content in this div, I have the following in my create.rjs file: page.replace_html :testly, :partial = 'test' Simply put, this should just refresh the partial right? But its not working... Would love any suggestions!

  • Strange tab ordering when creating controls after postback

    - by Crackerjack
    I have a button that opens a panel in a popup window and then performs a postback to retrieve data from the server and render some controls. Some of the controls are textboxes and some are dropdown lists and can be in any order. Everything works fine when tabbing through the textbox controls. But when tabbing from the first dropdown contorl found, the tab order 'gets lost' and it starts tabbing from the first control again. When I tab to the same dropdown list the second time 'round, it correctly tabs to the next control. Does anyone know what might be going on? Example: TextBox1 (Tab -> focus set to 'TextBox2') TextBox2 (Tab -> focus set to 'DropDown1') DropDown1 (Tab -> focus goes back up to 'TextBox1' - wtf?) TextBox3 Update: The TabIndex attribute is set on all controls.

  • Why is the proper "respond_to" format not getting called?

    - by humble_coder
    Hi All, I'm having a bit of an odd issue. Really too odd to type out, but here goes. Basically I have a controller that refuses to "respond_to" using javascript unless I assign my "chart.generate_xml" to a variable before the "respond_to" block like so: @xml = @chart.generate_xml(@begin_date,@end_date,1.hour) respond_to do |format| format.html format.js{ render :update do |page| page.insert_html :bottom, "chart-div", @xml #page.insert_html :bottom, "chart-div", @chart.generate_xml(@begin_date,@end_date,1.hour) end } If I remove the upper "@xml= …" portion and go with the lower "page.insert", the "format.js" section doesn't get called. And if I try to force the format with "request.format = :js", I get the javascript returned as text. I'm not doing anything special here in that method call, so I'm not sure why it would choose to respond any differently. FWIW, the method that triggers this controller action is using JS to do so, so I'm confused as to why "format.js" isn't always getting called. Thoughts? Best.

  • Sending BLOBs in a JSON service,... how?

    - by Marten Sytema
    Hello I have a webservice (ie. servlet) implemented in Java. It gets some data from a MySQL table, with one column being of type BLOB (an image), and some other columns are just plain text. Normally I would store the file outside the database with a pointer to it in the database, but due to circumstance I now have to use this BLOB column... What is the proper way to send this? How to encode the image in a JSONObject, and how to parse (and RENDER!) it on the otherside ? I want to use JSONP, to avoid having to proxy it through the consumer's webserver. So that the consumer can just put in a tag pointing to the webservice, calling a callback. Any thoughts how to handle images in this situation? Also thoughts on performance etc. are interesting!

  • How to change the HTML text to Right-to-Left order when rendering the text within a WebBrowser.

    - by Java Doe
    hi, I am using a WebBrowser to render some HTML text. The WebBrowser is located within a rich client. I can detect the window's orientation when the rich client is launched. How do I make the text rendered within the WebBrowser to be dispayed in RTL order. I have tried body.setDir("rtl"), but it only aligned all the text in the WebBrowser to the right. It does not really reverse the content. For example, I have a photo that is displayed on the left and then a segment of text displayed on the right. After calling body.setDir("rtl"), it only aligned everything to the right in the WebBrowser, but it did not move the photo to the right, and it did not move the text to the left. Thanks a lot!

  • Django: Can class-based views accept two forms at a time?

    - by Hooman
    If I have two forms: class ContactForm(forms.Form): name = forms.CharField() message = forms.CharField(widget=forms.Textarea) class SocialForm(forms.Form): name = forms.CharField() message = forms.CharField(widget=forms.Textarea) and wanted to use a class based view, and send both forms to the template, is that even possible? class TestView(FormView): template_name = 'contact.html' form_class = ContactForm It seems the FormView can only accept one form at a time. In function based view though I can easily send two forms to my template and retrieve the content of both within the request.POST back. variables = {'contact_form':contact_form, 'social_form':social_form } return render(request, 'discussion.html', variables) Is this a limitation of using class based view (generic views)? Many Thanks

  • Using XSL-FO and HTML?

    - by buggy1985
    Hi, I'm trying to transform some XML-data to HTML with XSLT for my bachelor thesis. My professor wants me to consider XSL-FO too, or at least to write some word about it. But I'm very noob to this. So my questions are: Can I combine FO with HTML? Can I use FO istead of HTML and CSS? If yes, how will my browser render this? Are there any examples/tutorials on how to transform xml into web pages with FO? Thank you very much.

  • Weird Rails URL issue when rendering a new action

    - by Tony
    I am rendering a new action but somehow getting the "index" URL. To be more specific, my create action looks like this: class ListingsController < ApplicationController def create @listing = Listing.new(params[:listing]) @listing.user = @current_user if @listing.save redirect_to @listing else flash[:error] = "There were errors" render :action => "new" end end end When there are errors, I get the "new" action but my URL is the index URL - http://domain.com/listings Anyone know why this would happen? My routes file is fairly standard: map.connect 'listings/send_message', :controller => 'listings', :action => 'send_message' map.resources :listings map.root :controller => "listings" map.connect ':controller/:action/:id' map.connect ':controller/:action/:id.:format'

  • Using JS to POST a form in an iframe.

    - by Stavros Korokithakis
    I would like to POST a form in an iframe, generated like so: My JS loads an iframe inside the page, adds a form to the iframe and submits the form. What I would like to happen is the iframe to load the result of that request. So, I would effectively like to post a form and render the result inside the iframe, without touching the parent (apart from putting the iframe up for display in the first place). I am using the code from this answer: http://stackoverflow.com/questions/133925/javascript-post-request-like-a-form-submit/134003#134003 but I can't get it to not reload the parent. I post the form, and instead of the iframe refreshing, the entire parent refreshes. I don't know why that is, since the url it's posting to is different and would at least redirect there. Can anyone help me with this problem? I just want a post inside an iframe and only within the iframe, basically.

  • A follow up on type coercion in C++, as it may be construed by type conversion

    - by David
    This is a follow up to my previous question. Consider that I write a function with the following prototype: int a_function(Foo val); Where foo is believed to be a type defined unsigned int. This is unfortunately not verifiable for lack of documentation. So, someone comes along and uses a_function, but calls it with an unsigned int as an argument. Here the story takes a turn. Foo turns out to actually be a class, which can take an unsigned int as a single argument of unsigned int in an explicit constructor. Is it a standard and reliable behavior for the compiler to render the function call by doing a type conversion on the argument. I.e. is the compiler supposed to recognize the mismatch and insert the constructor? Or should I get a compile time error reporting the type mismatch.

  • Ruby: "do this task eventually"

    - by marienbad
    I hope this question is clear enough -- if not let me know :) What API would I use when I want to write a procedure at runtime and then just run it eventually at low priority while continuing to do the important stuff right now? Example: link checker 1. I write a blog post with links represented by Link objects. I publish the post. 2. Eventually (at very low priority) the system gets around to fetching the URL of each Link object to make sure it's not broken and indicates that in a property of the Link object. 3. When a user visits my blog post, the render code that turns Link objects into HTML knows whether the links have been checked. I'm assuming there's a very general purpose API for doing this kind of "eventually/low priority" stuff.

  • ASP.NET MVC - Add XHTML into validation error messages

    - by Neil
    Hi, Just starting with ASP.Net MVC and have hit a bit of a snag regarding validation messages. I've a custom validation attribute assigned to my class validate several properties on my model. When this validation fails, we'd like the error message to contain XHTML mark-up, including a link to help page, (this was done in the original WebForms project as a ASP:Panel). At the moment the XHTML tags such as "< a ", in the ErrorMessage are being rendered to the screen. Is there any way to get the ValidationSummary to render the XHTML markup correctly? Or is there a better way to handle this kind of validation? Thanks

  • How to use custom color for each textview in listview that extends SimpleAdapter in Android ?

    - by mob-king
    I have a listview with custom rows and that extends SimpleAdapter. Each row consist of two linear layouts : 1st having two textviews of which one is hidden in horizontal orientation, second having two textviews in horizontal orientation. Now depending on the value in hidden textview , I want to setcolor for the remaining items for the row. To put it as simple: each listview item has some custom colors the value of which comes from the hidden field. I have done this by overriding getview() for the simpleadapter and returning view for each, but this makes list very slow to render (and that I think is obvious as so much of work for each view before showing it). Can I do this in some more efficient way ? like making views and then add up to list instead of using xml layout maybe one solution OR any other ? Any help ? Thanks.

  • Can I prevent RequiredFieldValidation from triggering against postbacks from a specific control.

    - by marcusstarnes
    I have a web form with a number of textbox controls which I've associated RequiredFieldValidator's with. I have a ValidationSummary control on the page to render any incomplete fields when I submit the page. However, I've just had to add an image upload facility to the same page, and have an 'Upload' button which I have posting back to perform the upload. I don't want this upload button to trigger the RequiredFieldValidators for the rest of the page though - I want this upload postback to be ignored as far as the validation goes. What's the best way to stop the RequiredFieldValidator's from firing when I submit this upload button on the page because at the moment, the upload won't occur unless I have first field out all of the other textbox controls on the page.

  • FileContentResult and international characters

    - by suzi167
    Hello, I am using a fileContentResult to render a file to the browser. It works well except that it throws an exception when the fileName contains international characters. I remember reading somewhere that this feature does not support international characters but I am sure there mustbe a workaround or a best practice people follow in cases the application needs to upload files in countries other than US. Does anyone know of such a practice?Here is the ActionResult Method public ActionResult GetFile(byte[] value, string fileName) { string fileExtension = Path.GetExtension(fileName); string contentType = GetContentType(fileExtension); //gets the content Type return File(value, contentType, fileName); } THanks in advance Susan

  • How can I use SiteMap more efficiently?

    - by Bipul
    So, in our website we are using SiteMap. For each request we render some menu and to do that we do SiteMap.RootNode in the helper function. Now, when I have done the profiling of my website using dotTrace, I saw the get_RootNode() is taking lot's of time(around 70-75 millisecond). But we know that the SiteMap is static. So, I am thinking in somehow I will get the SiteMap.RootNode only once in Application_Start and will access that through out each request. So, my questions are, Is my approach correct? How should I do that? Or is there any efficient way that I can use SiteMap.RootNode Thanks.

  • What is the easiest way to add some simple blog functionality to my website?

    - by Eric
    I've got a website, already hosted, and I'd like to add a blog section to it. However, I'm running out of time, so am looking for a quick and dirty solution. Ideally, I'd like to use something like blogger or wordpress and integrate it into my site, rather than starting from scratch. Is this easy to do? Or would it be simpler to grab the RSS feed from a blog hosted on that site, and render it with XSLT? Can anyone give me some suggestions on the easiest way to include this?

  • Is there a way to efficiently update one value in dojo chart2d?

    - by Nick Orlowski
    I am looking for a way to update one and only one value in a dojox chart2d. There is a way to update an entire series, which involves mychart.updateSeries("myseriesname",array_of_data) mychart.render() but This is too slow for my application. What I want to do is be able to drag the mouse over a vertical bar chart and have the values change as I am doing it. Only one or two values will need to change, so there is no need to reload all of the plots, just the two or three values that are changing. Is there a method that will quickly update only one or two values without lag? Thanks, Nick O I may just end up writing my own css version :S
