  • Is the Spark View Engine for ASP.NET dead?

    - by AUser
    Is the Spark View Engine for ASP.NET dead? I'm considering using it for a new project. I tried to get approved to the Google Groups but nobody would approve me. The last message posted there was in May. I tried emailing the developers but nobody would reply back. I'm not having happy feelings about this using SPARK for a major project of mine at the moment. Is this project now dead especially after the Razor came out?

  • Bitmapdata heavy usage - memory disaster (spark/FB4)

    - by keyle
    I've got a flex component which works pretty well but unfortunately turns into a disaster once used in a datagroup item renderer of about 40-50 items. Essentially it uses bitmapdata to take screenshot of a fully-rendered webpage in mx:HTML (this version of webkit rocks btw, miles better than flex 3). The code is pretty self-explanatory I think. http://noben.org/show/PageGrabber.mxml I've optimized it all I could, browsed, search for answers and already trimmed it down a lot, I'm desparate to reduce the memory usage (about 600mb after 100 draw) The Garbage collector has little effect. Thanks! Nic

  • Flex 4 how to layout spark controls in an html table type way

    - by Amy
    I have a group of controls and I want to organize them in a table like fashion. I want 1 row and 6 columns. Col 1,3,4,5,6 should all auto size to the contents and col 2 should take up the remaining available space. When the size of the group changes, only col2 width should change. I also want to be able to set the alignment of each cell. How can I do this in flex 4? I found a reference to mx:constraintColumns but this seems to be used with the canvas and in flex 4 adobe suggests not using canvases. Is there something similar in flex 4? I'm looking for something along the lines of Grid/Grid.ColumnDefinitions in silverlight.

  • How to add Flex 4 spark List Item custom properties

    - by maik3l
    I'm trying to make a simple flash application providing interface for taking tests as a high school assignment. One of the requirements is to use an XML file as data source.Now, having a List component bound to the XML file with questions consisting of data such as question body, question type (ie. single choice, multiple choice, open, image etc.) and possible answers (where applicable), I was wondering if I could add some additional data (and what is the best possible way to do so) to each question upon its transfer to the List component. I am trying to achieve two main goals with this: firstly, to mark the questions to which an answer has already been given, like with such code in ItemRenderer class: <s:Label color="{data.color}" text="{data.label}"/> where data.color would be set whenever the user gives an answer to a question. Secondly, while at it, I thought of such possibility as a great way to store answers given to particular questions. In this case, the Class of the answer object would have been Object, since there has to be many type of questions (where the answer could also be a Bitmap for example). This is a question of both how to do it and if it seems a good idea at all (and if no, if there is a better way?), because I am quite new to the whole Flash Builder and Flex thing and I am not really accustomed to all the possibilities and best practices. Thanks!

  • Refer to a Spark view component in code

    - by David
    I'm building a mobile AIR app using Flash Builder 4.5. The initial view in my views package is TestHomeView.mxml. I want to refer to it in one of my .as classes elsewhere in the app, and I'm not sure how to do that. Theoretically I should be able to add an "id" attribute to TestHomeView.mxml, but FB gives me an error: "id is not allowed on the root tag of a component". The root tag is s:view. The reason I need to do this is that within another class I make various calculations and then need to pass an array of values to a component in my view class. So in SomeOtherActionScriptClass.as I first assemble the array, myArray, and then in that class I want to do this: myViewComponent.viewArray = myArray; If I'm going to do that, I also need to import the view class into the .as class, which strikes me as weird. So is there a simple way to do what I want, or do I have to dispatch a custom event which contains the array, and listen for it in the view class? Thanks.

  • Flex4: Detect source Video size VideoPlayer?

    Hi, Is it possible in Flex 4's VideoPlayer control (spark.components.VideoPlayer) to detect some attributes of the source video? In my case, it's a local file. I would need to detect the original width and height of the input source video (an h264 f4v). Thanks

  • Is SparkViewEngine dying?

    - by Stephane
    Hey, I am building a email service based on templates. I thought of using the spark view engine but it seems that It doesn't get much updates anymore. Support on .NET4.0 is not even yet complete and it fails at runtime when used in a console app. The little Intellisense support that was there in VS2008 doesn't seem to work on VS2010 (from the information I have found) Should I avoid it? What do you think?

  • Flex 4: How to center a component that is larger than its container?

    - by Liviu
    Hi Everyone! I am using Flex 4 Spark Components for this one. I have a custom component that is larger than a certain container, and I need it to be centered in that container. Best using only MXML, styles and properties This does not work as expected: <s:BorderContainer x="300" y="300" width="200" height="200"> <s:Button label="Not centered" horizontalCenter="0" verticalCenter="0" width="300" height="250"/> </s:BorderContainer> Thanks!

  • Disable Flex CSS type selector warning?

    - by davr
    I'm building a somewhat large Flex project that includes several modules (a single Flex project that produces multiple SWFs) Right now, I have a single css file, being loaded in the main SWF tag: <s:Application ... > <fx:Style source="css/main.css" /> ... </s:Application> In the CSS file: /* CSS file */ @namespace s "library://ns.adobe.com/flex/spark"; s|Panel { skinClass: ClassReference("com.skins.DefaultPanelSkin"); } s|Button { skinClass: ClassReference("com.skins.DefaultButtonSkin"); } The CSS file is not referenced anywhere else. I have currently 6 modules (plus the main SWF, a total of 7 SWFs). I've noticed that the number of warnings is correlated to the number of modules...every time I add a module, I get more warnings. Right now, I get 6 warnings for every entry in the CSS file, so: CSS type selectors are not supported in components: 'Panel' CSS type selectors are not supported in components: 'Panel' CSS type selectors are not supported in components: 'Panel' CSS type selectors are not supported in components: 'Panel' CSS type selectors are not supported in components: 'Panel' CSS type selectors are not supported in components: 'Panel' And repeat for Button, TextArea, etc etc. I have so many useless warnings, it is impossible to see if there are any valid ones. Is this warning caused by something I'm doing wrong? The styles are all being applied correctly and appears to work just the way I want at runtime. If I'm doing nothing wrong, can I tell the compiler to ignore this warning? NOTE: I've tried the -show-unused-type-selector-warnings=false compiler flag, and it does not work...that's for a similar but different warning.

  • How do I get the collection of Model State Errors in ASP.NET MVC?

    - by Ryan Montgomery
    How do I get the collection of errors in a view? I don't want to use the Html Helper Validation Summary or Validation Message. Instead I want to check for errors and if any display them in specific format. Also on the input controls I want to check for a specific property error and add a class to the input. P.S. I'm using the Spark View Engine but the idea should be the same. So I figured I could do something like... <if condition="${ModelState.Errors.Count > 0}"> DispalyErrorSummary() </if> ....and also... <input type="text" value="${Model.Name}" class="?{ModelState.Errors["Name"] != string.empty} error" /> .... Or something like that. UPDATE My final solution looked like this: <input type="text" value="${ViewData.Model.Name}" class="text error?{!ViewData.ModelState.IsValid && ViewData.ModelState["Name"].Errors.Count() > 0}" id="Name" name="Name" /> This only adds the error css class if this property has an error.

  • ASP.NET MVC View Engine Comparison

    - by McKAMEY
    EDIT: added a community wiki to begin capturing people's experience with various View Engines. Please respectfully add any experiences you've had. I've been searching on SO & Google for a breakdown of the various View Engines available for ASP.NET MVC, but haven't found much more than simple high-level descriptions of what a view engine is. I'm not necessarily looking for "best" or "fastest" but rather some real world comparisons of advantages / disadvantages of the major players (e.g. the default WebFormViewEngine, MvcContrib View Engines, etc.) for various situations. I think this would be really helpful in determining if switching from the default engine would be advantageous for a given project or development group. Has anyone encountered such a comparison?

  • Is there any reasons to prefer SparkViewEngine over XSLT (or vice versa) for a standalone email gene

    - by Stephane
    I have a service that receives an object containing all the data needed to build a newsletter. I need to be able to generate the email using different templates. I don't want to involve the whole ASP.NET stack for that, so I want a separate templating engine. Reading a lot of opinions, I have found that XSLT was not getting very much love when it comes to templating engines. Why? SparkViewEngine is a "new cool toy", but it seems mature enough considering the number of projects that have been built with it. What do you think? Did you used those 2 engines? in which situation, and what strength/pain did you enjoy/endure

  • MVC2 Areas not Registering Correctly

    - by Geoffrey
    I believe I have my Areas setup correctly (they were working in MVC1 fine). I followed the guide here: http://odetocode.com/Blogs/scott/archive/2009/10/13/asp-net-mvc2-preview-2-areas-and-routes.aspx I've also used Haacked's Route Debugger. Which shows the correct Area/Controller registration when I run it. However when I try to go to my (AreaName)/(Controller) I get this error: "The resource cannot be found." I believe this indicates there's a problem with the routing, but I'm having trouble debugging this. Where should I set my breakpoints to catch routing errors in MVC2? I'm also using SparkViewEngine compiled against MVC2 references. Could this possibly be causing this error? I've set breakpoints on the controller in the area and it never fires off, I assumed the view engine doesn't kick in until after the controller has been initiated, but I could be wrong. The non-area landing page works fine, and I've stripped my project of all areas except one, to avoid any sort of naming conflicts. Any ideas where I can try to look next?

  • Setting button width with fx:Style

    - by Kamo
    I have 4 buttons, all of them have the same width. <s:Button id="btn1" width="{btnWidth}" /> <s:Button id="btn2" width="{btnWidth}" /> <s:Button id="btn3" width="{btnWidth}" /> <s:Button id="btn4" width="{btnWidth}" /> Is it possible to set their width with Style, something like this: s|Button{ width: btnWidth; } I tried it, but auto-complete isn't working, which leads me to think that there's something wrong with the syntax. Basically my goal is to not have the width property set specifically for all 4.

  • How can I use the Spark library in my ActionScript project?

    - by bluenote
    I'm using Flare to develop a visualization. Being familiar to Java, Javascript and Eclipse it wasn't a big deal to familiarize myself to developing with Actionscript and Adobe FlashBuilder. I actually found that the learning curve is very flat. However, being new to Actionscript, I can't figure out how to use the Spark libraries that are part of Flex. I tried to add the libraries to the build path, with no success. I guess I'm confused about how Flash, Flex, Actionscript, Spark and Flare work together, even after reading the helpful answers on this question Does anybody know which part of the puzzle I'm missing? Thanks.

  • Is it normal for the laptop charger to spark when plugging in?

    - by Cd-MaN
    All the laptop chargers I had until now sparked whever I plugged them in. This is true for my old charger (the bulkier / rounder Dell model) and the new charger (the flat Dell model) with two different Dell laptops, however until recently I didn't give it much thought. Then, in the last couple of months: I shorted out a conference room and melted the floor a little (the wire caught fire) The second charger (also a Dell original) died, taking the power strip with it I'm wondering: Is it normal for laptop chargers to spark when plugged in? Specifically new, original Dell chargers Is there a "correct" way to plug / unplug chargers? Do I need to first unplug it from the wall and then from the laptop / do I need to first plug it into the wall and then into the laptop? May the problem be caused by the fact that I leave sometimes the charger plugged into the wall without connecting the laptop for longer periods of time (up to a day)? PS. I'm talking about Europe, so 220V and this happens in many places (at home, at my parents, at work, in hotels I trave to, etc)

  • Meteor exception in Meteor.flush when updating a collection breaks reactivity across clients

    - by Harel
    When I'm calling Collection.update from the front end (the method call is allowed), the update does work ok, but the exception below is being thrown (in Chrome's JS console, not in the server). Although the update took place, other clients connected to the same collection do not see the updates until they refresh the browser - I suspect because of the exception. Any idea what might cause this?
