  • How to disable Middleware and Request Context in some views.

    - by xRobot
    I am creating a chat like facebook chat... so in views.py of my Chat Application, I need to retrieve only the last messages every 3-4 seconds with ajax poll ( the latency is not a problem for me ). If I can disable some Middlewares and some Request Context in this view, the response will be faster... no ? My question is: Is there a way to disable some Middlewares and some Request Context in some views ?

  • Can I use Blender to create 3D wall image viewer application under Linux?

    - by sgon00
    Hi, Is that possible to use Blender to create Cooliris-like 3D wall image viewer application under Linux? I don't see many people use Blender (BGE) to create desktop application, so I am wondering if this is possible. People normally use Blender for modeling/movie and game engine. I can not find a good way to create 3D application in Linux so far. I was thinking about pyQT+opengl. But I feel that is hard to do. No robust and easy-to-use qt+opengl toolkit available from my research. I know a little bit of Blender, that's why I am asking if Blender is an alternative solution. (python is preferred) The image viewer doesn't have to be windowed. It can be full screen, like a game?. I would like to add many cool effects into this application. Hopefully cooler than Cooliris which is written in flash. Thanks a lot.

  • jQuery datepicker calendar - call to function updates database

    - by erbaker
    So I'm using the datepicker plugin to make an availability calendar. Here is my javascript: http://pastebin.com/H7D9PcAg When dpSetSelected() is called it is also calling dateSelected() which triggers the AJAX call to my PHP script. I need a way to only update the database if the date is clicked on and not pre-loaded. When I pre-load the dates they are sent to the PHP page and subsequently removed.

  • Problems with Unity BuildUp Method

    - by Voice
    Hi everybody) I'm using Unity App Block for my project (version 1.2.0.0). I have a problem with Unity Container BuildUp method which I'm using for my ascx controls. Here is some code (that's pretty simple) public class BaseUserControl<T>:UserControl where T:class { protected override void OnInit(EventArgs e) { InjectDependencies(); base.OnInit(e); } protected virtual void InjectDependencies() { var context = HttpContext.Current; if (context == null) { return; } var accessor = context.ApplicationInstance as IContainerAccessor; if (accessor == null) { return; } var container = accessor.Container; if (container == null) { throw new InvalidOperationException("No Unity container found"); } container.BuildUp<T>(this as T); } } This method is called in base control for ascx controls in my solution. And here the property that should be injected in child control: [Dependency] private IStock Stock { get; set; } So after buildup Stock property is still empty. Resolve method works fine for IStock with the same container and configuration. I've tried buildup with simple test class with only one property IStock and got the same result. So what can be wrong with buildup?

  • IE textarea wrap bug?

    - by user2227033
    It seems that IE starting from IE7 to IE10 wraps text in the textarea control incorrectly when using \n (or \r\n - doesn't matter - results are the same). Is this a bug in IE or they treat the html standard differently than other browsers - who is right? I have defined: <textarea id="TextArea1" runat="server" style="width: 190px; height: 390px; white-space: normal; word-wrap: normal; overflow: scroll" ></textarea> When I try to add long string like "VeryLongStringEndingWithNewLine\n" by using JavaScript code (obj.value += text;) the text is shown in one line with scroll (this is ok) but added with an additional empty line (\r\n) - why? When I try to add short string like "Short\n" multiple times, again via JavaScript code the text is on the same line (should be on the separate lines because normal wrapping should be applied). Moreover when I do postback then all \r\n's are replaced with spaces (why?) and then text parsed correctly (assuming if I used spaces instead of crlf normal wraping with space only wraps when does not fit in the area). When using FF or Chrome same control behaves correctly - long lines are shown without an additional empty next line, short lines are on the different lines, no replacement with spaces when doing postback. I know I could probably use other options or white space characters, but I feel that above is not correct about IE. Any comments? Mindaugas

  • Silverlight + Facebook DTK API -> SecurityException ONLY on Mac and Firefox...

    - by santiago
    I have a SilverLight application which throws a security exception when running on FireFox for Macs. The exact same application works fine on Windows (Internet Explorer, FireFox, Chrome, Opera) and on Safari for Macs. I am using the Facebook Developer Toolkit available on Codeplex. The exception is thrown when the user launches the App. At that time I use the SilverLight Facebook API to run some queries using: facebookAPI.Fql.MultiqueryAsync(queries, QueryAppUsersCompleted, dispatcher); In my callback function QueryAppUsersCompleted, the FacebookException does not evaluate to null, and its innerException property has a SecurityException in it. Any help would be tremendously appreciated.

  • OpenCL support on Leopard

    - by koan
    I want to use OpenCL in my software but I am running Leopard. I will probably update to Snow Leopard later. In the mean time I would like to get started with OpenCL in Leopard. Setting up on 10.5 is confusing: most SDKs and articles assume that you must be using Snow Leopard. Searching for "Using OpenCL on Leopard" is completely useless, as you would expect. I downloaded the cuda toolkit, devdriver and gpucomputing SDK from nvidia but the examples won't compile because OpenCL/opencl.h is not found. The OpenCL release notes don't mention MacOSX so again I think this is assuming that all Mac users are running Snow Leopard. Where can I find OpenCL includes and libraries for Mac OSX 10.5 ? Or, is this just a waste of time and I should go and get Snow Leopard ASAP ? After upgrading to Snow Leopard I would like my software to support Leopard. Is this possible ?

  • Line by line image swing

    - by user1046017
    I want to show an image as it is downloading, I have the URL, and I am trying to get the image parts like this: InputStream openStream = url.openStream(); DataInputStream dis = new DataInputStream(new BufferedInputStream(openStream)); ByteArrayOutputStream os = new ByteArrayOutputStream(); while ((s = dis.read(b)) != -1) { os.write(b , 0, s); support.firePropertyChange("stream", null, os); } This way, any listener get the stream and creates an image, this way: if("stream".equals(evt.getPropertyName())){ try { ByteArrayOutputStream stream = (ByteArrayOutputStream) evt.getNewValue(); byte[] byteArray = stream.toByteArray(); stream.flush(); Image createImage = Toolkit.getDefaultToolkit().createImage(byteArray); this.getContentPane().add(new JLabel(new ImageIcon(createImage))); } catch (IOException ex) { Logger.getLogger(ImageTest.class.getName()).log(Level.SEVERE, null, ex); } } However, I am getting a "Premature end of JPEG file sun.awt.image.ImageFormatException: JPEG datastream contains no image" error, the image is a JPG image format, is there any library or method known to make something similar?

  • Bind an Incode DataTemplate in WPF

    - by Mike Bynum
    I have a WPF Application which is using MVVM. I know that there ways of doing this in XAML but I am working on a plugin architecture and came up with a solution where a plugin exposes it's viewmodel to my plugin host's viewmodel and it's datatemplate. I want to leave the lifetime management of the plugin view up to WPF. I have tried having the plugins expose a UserControl but ran into issues when WPF decided to dispose of my UserControl so I would not reattach it without weird hacky work arounds. I am having issues getting some sort of binding working to where i can bind a control to the data and it's template to my data template. I have a ViewModel which looks something like: public class MyViewModel { public DataTemplate SelectedTemplate{ get; set;} public object SelectedViewModel {get; set;} } The selected template and viewmodel are determined somewhere else in the code but are irrelevant to my question. My question is how i can bind to a DataTemplate so that I know how to display the data shown in the SelectedViewModel. The DataTemplate is a DataTemplate created incode which respresents: <DataTemplate DataType="{x:Type vm:MyViewModel}"> <v:MyUserControl /> </DataTemplate> I have tried: <UserControl Template="{Binding Path=SelectedTemplate}" Content="{Binding Path=SelectedViewModel"} /> But UserControl expects a control template and not a data template.

  • Embedded scripting engine in .Net app

    - by Nate
    I am looking to replace an old control being used for scripting an application. The control used to be called SAX Basic, but is now called WinWrap. It provides us with two primary functions. 1) It's a scripting engine (VB) 2) It has a GUI for developing and debugging scripts that get run in the hosting application. The first feature it provides is actually pretty easy to replace. There are so many great methods of running just about any kind of code at runtime that it's almost a non-issue. Just about any language targeting the .Net runtime will work for us. We've looked at running C#, PowerShell, VB.Net, IronPython, etc. I've also taken a brief look at Lua and F#, but honestly the language isn't the biggest barrier here. Now, for the hard part that seems to keep getting me stuck. We want a code editor, and debugger. Something simple, not unlike PowerShell's ISE would be fine. Just as long as a file could be created, saved, debugged and executed. I'm currently looking into Visual Studio 2010 Shell (Isolated) and I'm also looking at the feasibility of embedding PowerShell ISE in my application. Are there any other editor's I could embed/use in my application? Purchasing a product is not out of the question. It comes down to a combination of ease of use, how well it meets our needs, and how simple deployment and licensing is for developers. Thanks for the pointers

  • How to handle 30k files in a project which requires them?

    - by Jeremiah
    Visual Studio 2010 RC - Silverlight Application We have a library of images that we need to have access to. They are given to us from a vendor (through an installer) and they are not in a database, they are files in a folder (a very large monster of a folder). We do not control when the images change, so the vendor needs to be able to override them individually. We get updates frequently enough from this vendor to state that these images change "randomly" and without our (programmer) knowledge. The problem: I don't want 30K images in SVN. Heck, I don't even want to imagine them in my Solution. However, our application requires them in order to run properly. So, our build/staging servers need access to these images (we have two build servers). The Question: How would you handle it when your application will not work as specified without access to each of 30k images and you don't control when those images change? I'm do not want to have a crazy large SVN repository. Because I don't know when any of these images change, I really don't want them in my solution (definitely do not want a large solution, either). I also don't want a bunch of manual steps to do every time these images change. Our mantra, up to this point, has always been, any developer could download from SVN, compile and run our app. These images are going to kill that mantra. I'm tempted to make a WCF service that will return images if they exist and a dummy image if they don't. This way all dev boxes will return a dummy image and our build/staging/production boxes will return real images (ones that actually have the vendor's image installer installed on). This has to be a solved problem. What have other people done to handle these types of problems? I'm open to suggestions.

  • How can I run an appear effect and a fade effect in scriptaculous? I need them to run in tandam so t

    - by LeeRM
    Hi, Ive been fiddling with this for hours and hours and just cant get it right. First off my sites are already using Prototytpe and Scriptaculous, and to change would take a long time. Basically I am after achieving a slideshow effect similar to jQuery Cycle plugin. I have written most of it but cant get over this hurdle: I need the user to be able to press a control button which will skip the slide to which ever one they have picked. My problem is that if a fade / appear effect is running, then it causes an overlap. I am using queues and they are in their own scope. The problem as I see it is that the fade effect on one slide and the appear effect on the next slide are separate functions. Which means that if the user clicks the control button to move to another slide whilst the animation is inbetween fade & appear, then the next cycle will slot itself in the queue between those 2 effects. The default is to append to the end of the existing queue, which should be fine. But if the appear hasnt been added when a new fade is instantiated, then the queue messes up. I can make it so nothing happens if animation is in effect but thats not the effect I am after. I want to be able to click a slide and whatever is happening to effectively stop and the next slide appear. This is an example of what I am after: http://www.zendesk.com/ Im sorry if that doesnt make sense. Its a tough one to explain. Thanks Lee

  • ASP.NET MVC Inheriting from ProfileBase

    - by Glen
    I have 2 related issues. I inherited from ProfileBase and I have a couple of properites as such public SomeType PropertyName { get { return (SomeType)base["PropertyName"]; } set { base["PropertyName"] = value; Save(); } } I also have a User class (UserId, UserName, Profile, LastActivityDate) that has 2 additional properties out of the profile that I retrieve in my View to show a list of Users (i.e. @Model.Profile.PropertyName). However, everytime I access a property (from my View) it seems to update the LastActivityDate in the aspnet_Users table because when I show the LastActivityDate as well as the profile properties on my screen the LastActivtyDate is out of sync with the database. Also there is a LastActivityDate property available in my profile which unfortunately is not available and is in fact set to null and throws an exception when accessing it saying the property UserName is null. So the static Create method provided by ProfileBase seems to retrieve the correct profile properties but does not set the base's UserName property even though you pass in a UserName parameter to the Create method. Is this a internal bug? I was kind of hoping if by accessing the property because the LastActivityDate is updated then I could store that value to update my LastActivityDate in my User class before it is rendered to the page. The only way I can think of doing it is: public SomeType PropertyName { get { SomeType result = (SomeType)base["PropertyName"]; OnLastActivityDateChanged(); return result; } set { base["PropertyName"] = value; } } then in my User class: ... public MyProfile() { Profile.LastActivityDateChanged += Profile_LastActivityDateChanged(); } ~MyProfile() { Profile.LastActivityDateChanged -= Profile_LastActivityDateChanged(); } ... void Profile_LastActivityDateChanged(object sender, EventArgs e) { //Run a query to get the latest LastActivityDate this.LastActivityDate = ... } It seems I have to make 1 call to retrieve the full list to my aspnet_Users table then another call for each row just to get the latest activity date. ARGGGGHHH!!! Am I going about this the wrong way! I put an ajax refresh hyperlink next to each User row and when I click it, immediately after loading the page, the value changes. Therefore my suspision is valid that calling a property via the inherited profilebase class updates the value. Is there a workaround? It is a bit miss leading when my page says User Smith has no activity for 4 days then I click my ajax refresh link (or refresh the whole page for that matter) and now it says Smith was active but it was just me meally showing the page that indirectly caused an activity read event.
