  • Frame.Navigate to an embedded resource F#

    - by akaphenom
    I have a 100% silverlight 3.0 / f# 2.0 application I am wrapping my brain around. I have the base application loading correctly - and now I want to add the naigation controls to it. My page is stored as an embedded resource - but the Frame.Navigate takes a URI. I know what I have is wrong but here it is: let nav : Frame = mainGrid ? mainFrame let url = "/page1.xaml" let uri = new System.Uri(url, System.UriKind.Relative) ; nav.Navigate uri Any thoughts?

  • Multiple .obj Models in THREE.js and detecting clicked objects

    - by ZedBee
    I have been following along this example to load .obj Model using three.js. Since I needed more than one model to load so I tried this loader.addEventListener( 'load', function ( event ) { var object = event.content; object.position.y = - 80; scene.add( object ); }); loader.load( 'obj/model1.obj' ); loader.load( 'obj/model2.obj' ); First: I don't know whether this is the right approach or not since I searched but didn't find any tutorial loading more than one .obj models. Second: I want to be able to click different models on the screen. I tried this which doest not seem to work for me. Any suggestions on this?

  • Preload a lot of tiny pics

    - by clorz
    I'm thinking about how to approach the problem at hand. There's a flash movie that requires a lot of relativly small images and I'm trying to optimize the time it takes for them to be preloaded. One thing I've considered it turning on KeepAlive in Apache on the server side. That works. But my mind still wonders if there's anything else ;-) So, what other approaches I may try? Is there a way to compress all those images and then unpack on client side? I have full control on both server and client side. Can even try installing something other than Apache. Cache is not an option because it already works and it's first time loading that bothers me here.

  • Read vector into CUDA shared memory

    - by Ben
    I am new to CUDA and programming GPUs. I need each thread in my block to use a vector of length ndim. So I thought I might do something like this: extern __shared__ float* smem[]; ... if (threadIddx.x == 0) { for (int d=0; d<ndim; ++d) { smem[d] = vector[d]; } } __syncthreads(); ... This works fine. However, I seems wasteful that a single thread should do all loading, so I changed the code to if (threadIdx.x < ndim) { smem[threadIdx.x] = vector[threadIdx.x]; } __syncthreads(); which does not work. Why? It gives different results than the above code even when ndim << blockDim.x.

  • Massive SQL issue shutting down our site.

    - by Pselus
    Our website has started timing out like crazy today. All of our clients are finding it unusable. The only error we can seem to trace down as a potential problem is this: SQLAllocHandle on SQL_HANDLE_DBC failed Error ASP Description Error Category Microsoft OLE DB Provider for ODBC Drivers I have no idea what it means or how to go about fixing it. Anyone ever encountered this error before? Currently, you can log in to our site, but then once you go to do anything else, you find yourself logged out or nothing happens. We have a lot of Ajax going on so the "nothing happens" probably has to do with the Ajax pages not loading properly due to logouts and so nothing displays to the user. Like I said, I'm at a loss. Anyone have any advice on this error?

  • Initialize content of a jQuery remote tab on initial page load

    - by Carl
    I'm using the jQuery tabs library to create a set of remote (i.e., ajax loaded) tabs. However, to avoid the initial page load being empty until the ajax request finishes, I'd like to include the content for the initial tab with the initial page download. I've got this generally working by providing a div in the initial page load that matches the title of the tab, but even though this content appears immediately, as soon as I initialize the tabs it does the ajax request IN ADDITION which is both wasteful and causes a flicker. My basic question is how can I get jQuery tabs to NOT do an ajax request for the initially selected tab, and get this content as part of the initial page load, while still loading the other tabs dynamically. The complication is that I can't hard code the ids/hrefs for which tab is the "initial" one since the initial tab will change based on available content. I'm sure there is some kind of hacky way to do this with javascript rewriting the URLs of tabs dynamically before I initialize the tabs but I'm looking for a cleaner solution. Any ideas?

  • Limited IList<> implementation ?

    - by Wam
    Hello people, I'm doing some work with stats, and want to refactor the following method : public static blah(float[] array) { //Do something over array, sum it for example. } However, instead of using float[] I'd like to be using some kind of indexed enumerable (to use dynamic loading from disk for very large arrays for example). I had created a simple interface, and wanted to use it. public interface IArray<T> : IEnumerable<T> { T this[int j] { get; set; } int Length { get; } } My problem is : float[] only inherits IList, not IArray, and AFAIK there's no way to change that. I'd like to ditch IArray and only use IList, but my classes would need to implement many methods like Add, RemoveAt although they are fixed size And then my question : how can float[] implement IList whereas it doesn't have these methods ? Any help is welcome. Cheers

  • Rails: ValidationReflection and Formtastic not working together

    - by user336777
    I installed validation_reflection as a gem and out of the box it picked up on my validates_presence_of validations. But it is not picking up on any of the other default rails validations such as validates_format_of. I know from the documentation that i am supposed to add something like: config.reflected_validations << :validates_format_of to my config/plugins/validation_reflection.rb file (which didn't exist initially). I did this but nothing changed (i restarted the web server in between). I am not sure if it just isn't picking up on my file and loading validation_reflection.rb or if i have done something wrong. Anyone have any insights?

  • Why in landscape orientation in simulator all the subviews appear out of order?

    - by wolverine
    I was doing a sample app in ipad. I added about 4 to 5 imageviews to the left side of the view vertically. This view will appear when we select the corresponding entry in the splitviewcontroller. In ipad simulator too, all the images were loading and all are working fine in portrait orientation. But when I rotate the simulator to landscape orientation, these imageviews doesnt appear where i placed them. Some of them overlapping each other, some have half of their part in the navigation bar and all. Has gone completely out of order. I am confused why is all this happening. Can anyone help me solve this issue?

  • System.AccessViolation in DllImport method after redeploy

    - by gall
    Hi Everyone, My environment: Windows 2003, VS 2008, .NET 3.5 C# .NET application. During loading my application I call method from C++ dll (Knowl.dll) through my third-party dll library (Common.dll) written in C#. After first deploy (from VS to Developing server) evrything works fine. Then I stops Developing Server, doesn't any changes in code and redeploy. Throws AccessViolationException on this imported method. What is it? On second and after redeplies - the same error. Only after deletin source code and recheckout it from CVS I can normally start server. Dll import: [DllImport("Knowl.dll", EntryPoint = "GetBaseName")] private static extern IntPtr getNameDll(); public static string GetName() { IntPtr p = IntPtr.Zero; p = getNameDll(); return Marshal.PtrToStringUni(p); }

  • How can I block based on URL (from address bar) in a safari extension

    - by PerilousApricot
    I'm trying to write an extension that will block access to (configurable) list of URLs if they are accessed more than N times per hour. From what I understand, I need to have a start script pass a "should I load this" message to a global HTML page (who can access the settings object to get the list of URLs), who will give a thumbs up/thumbs down message back to the start script to deny/allow loading. That works out fine for me, but when I use the usual beforeLoad/canLoad handlers, I get messages for all the sub-items that need to be loaded (images/etc..), which screws up the #accesses/hour limit I'm trying to make. Is there a way to synchronously pass messages back and forth between the two sandboxes so I can tell the global HTML page, "this is the URL in the window bar and the timestamp for when this request came in", so I can limit duplicate requests? Thanks!

  • How to set ExportMetaData with multiple values as well as single w/ custom attribute ?

    - by Matthew M.
    I have the following ExportMetaData attributes set on my class: [Export(typeof(IDocumentViewer))] [ExportMetadata("Name", "MyViewer")] [ExportMetadata("SupportsEditing", true)] [ExportMetadata("Formats", DocFormat.DOC, IsMultiple = true)] [ExportMetadata("Formats", DocFormat.DOCX, IsMultiple = true)] [ExportMetadata("Formats", DocFormat.RTF, IsMultiple = true)] I also have a supporting interface: public interface IDocumentViewerMetaData { /// <summary> /// Gets the format. /// </summary> /// <value>The format.</value> IEnumerable<DocFormat> Formats { get; } /// <summary> /// Gets the name of the viewer /// </summary> /// <value>The name.</value> string Name { get; } /// <summary> /// Gets a value indicating whether this viewer supports editing /// </summary> /// <value><c>true</c> if [supports editing]; otherwise, <c>false</c>.</value> bool SupportsEditing { get; } } And of course my ImportMany: [ImportMany(typeof(IDocumentViewer))] public IEnumerable<Lazy<IDocumentViewer, IDocumentViewerMetaData>> _viewers { get; set; } What I would like to do is use a strongly-typed attribute class instead of using the ExportMetaData attribute. I have not figured out a way to do this while also supporting single values (Name, SupportsEditing, in the example above). I envision doing something similiar the following (or whatever is suggested as best): [Export(typeof(IDocumentViewer))] [DocumentViewerMetadata(Name = "MyViewer")] [DocumentViewerMetadata(SupportsEditing = true)] [DocumentViewerMetadata(Format = DocFormat.DOC)] [DocumentViewerMetadata(Format = DocFormat.DOCX)] I am fairly certain that there IS a way to do this, I just haven't found the right way to connect the dots. :) Thank you, Matthew

  • Choosing random action, Flash AS3

    - by esryl
    I have 2 actions in a Flash file that I would like to test for conversion. One is opening a link in a tab/window, the other loading the content in a Colorbox iframe over the page. How do I randomly choose one of the following actions? I currently listen for a click on a button: clickJoin.addEventListener(MouseEvent.CLICK,toJoin); My two actions are: navigateToURL(new URLRequest("http://www.google.com/"), '_blank'); and ExternalInterface.call('$.fn.colorbox({ href: "http://www.google.com/", width:"80%", height:"80%", iframe:true, onLoad:function(){ $("#player").css({"visibility":"hidden"}); }, onClosed:function(){ $("#player").css({"visibility":"visible"}); }}) ');

  • get the expanding node in a treeview

    - by Iulian
    I have a treeview control that functions like a folder browser. Because loading the entire folder structer from disk is taking a lot of time i'm trying to load only one level at a time. So i have a function that adds nodes for all the folders in the current node. I thought that the best method would be to run it on the BeforeExpand event of the treeview. UpdateTreeView(TreeView.SelectedNode); is not working because clicking the + sign to expand is not selecting the node also. So how to find the node that is expanding.

  • Empty list in appengine datastore: java vs python

    - by lOranger
    I have the following java model class in AppEngine: public class Xyz ... { @Persistent private Set<Long> uvw; } When saving an object Xyz with an empty set uvw in Java, I get a "null" field (as listed in the appengine datastore viewer). When I try to load the same object in python (through remote_api), as defined by the following python model class: class Xys(db.Model): uvw = db.ListProperty(int) I get a "BadValueError: Property uvw is required". When saving another object of the same class in python with an empty uvw list, the datastore viewer print a "missing" field. Apparently empty lists storage handling differs between Java and python and lead to "incompatible" objects. Thus my question: Is there a way to, either: force Java to store an empty list as a "missing" field, force Python to gracefully accept a "null" list as an empty list when loading the object? Or any other suggestion on how to handle empty list field in both languages. Thanks for your answers!

  • jQuery append Google Adsense to div..

    - by SoulieBaby
    Hi everyone, I'm having issues with google adsense and it loading before my jQuery and killing my codes, so I thought I'd try to append the Google Adsense javascript to the appropriate div using the document ready function, here's the code I'm trying to write: <script language="javascript" type="text/javascript"> $(document).ready(function(){ $(".googleBanners").html("<script language='javascript' type='text/javascript'>\n" + "google_ad_client = 'pub-8487967187298044';\n" + "google_ad_slot = '1088799521';\n" + "google_ad_width = 250;\n" + "google_ad_height = 250;\n" + "</" + "script>\n" + "<script language='javascript' src='http://pagead2.googlesyndication.com/pagead/show_ads.js' type='text/javascript'>" + "</" + "script>"); }); </script> But I'm not so good writing javascript/jQuery so if someone could help me implement this that would be fantastic. The error in FF I'm currently getting is "Error: google_protectAndRun is not defined". I'm not sure what that means, but I'm guessing I've written the jQuery code wrong.. lol

  • Winforms - Visually remove button click event

    - by Wayne Koorts
    .NET newbie alert Using Visual C# 2008 Express Edition I have accidentally created a click event for a button. I then deleted the automatically-created method code, which resulted in an error saying that the function, which had now been referenced in the form loading code, could no longer be found. Deleting the following line from the Form1.Designer.cs file's InitializeComponent() function... this.btnCopy.Click += new System.EventHandler(this.btnCopy_Click); ... seems to do the trick, however, it makes me feel very dirty because of the following warning at the beginning of the #region: /// Required method for Designer support - do not modify /// the contents of this method with the code editor. I haven't been able to find a way to do this using the form designer, which I assume is the means implied by this warning. What is the correct way to do this?

  • Using key().id() on GAE Datastore and reverse geocoding

    - by Ivan Slaughter
    I have 6000 data of district, subdistrict. I need to represent this on dependent dropdown. The datamodel is for example; class Location(db.Model): location_name = db.StringProperty() location_parent = db.IntegerProperty() location_parent is reference to key() or id()? Still cannot decide which one is good. When i use key() as reference then using JSON to create jquery dependent drop down. My page loading/query and rendering time the dropdown is quite slow? Can i use key().id() as drop down option value to lighten up the page load? Any better solution for this parent/child reference for the drop down? For example: for the district record/entities the location-parent is null, for sub district record location_name will contain reference to parent district record. Other issue is to reverse geocoding the location to store or display geoPoint (lat,long)? Is google MAP API always find the exact lat,long of specific region boundaries or any error checking for the result?

  • Using $.get with jquery validation

    - by Jimmy McCarthy
    I'm trying to use the Jquery builtin validator on my page. The issue is that I have certain fields that only are required if the JobID (entered into another field) does not already exist in our database. I have a simple service which simply takes JobID and returns True or False based on whether the JobID exists, but I can't seem to get this information where I want it. Some sample code: $("#dep_form").validate({ rules: { JobID: { required: true, digits: true, minlength: 3 }, OrgName: { required: function(element) { //This field is required if the JobID is new. return $("#jobinfo").html().length==15; } } }, messages: { JobID: { required: "Enter a Job Number.", digits: "Only numbers are allowed in Job ID's.", minlength: "Job Number must be at least 3 digits" }, OrgName: { required: "Select a Practice from the dropdown list." } }, errorClass: "ui-state-error-input", errorLabelContainer: "#errorbox", errorElement: 'li', errorContainer: "#validation_errors", onfocusout: false, onkeyup: false, focusinvalid: false }; Currently, I'm using a lazy method to validate (shown above). However, I now have access to a service using the URL: var lookupurl = "/deposits/jobidvalidate/?q=" + $("#id_JobID").val() + "&t=" + new Date().getTime(); which is a page which will contain just the word True or False based on whether that given JobID exists. I've tried half a dozen different ways of setting variables and calling functions within functions and still cannot get a way to simply return the value of that page (which I've been trying to access with $.get() ) to my validator, so that required is set to true when the Job does not exist and false if the job already exists. Any suggestions? Thanks.

  • IE7 Animated GIF Appears as a Static Image?

    - by Abs
    Hello all, After a button is clicked to start a process on my web app, I show a small loading gif (animated) that rotates to indicate to the user something is happening. I put the gif img in place of the button like this using JQuery: $('#btn_holder').html('<img src="images/loading2.gif" style="margin-left:40px; margin-top:7px;" />'); This works great in all browsers (Firefox, IE8, Chrome) except IE7 on a windows server 2003. In IE, the gif appears but it is not animated. What's going on with IE7? How can I test what the problem is? Thanks all

  • ASP.NET MVC and NHibernate coupling

    - by Ben
    I have just started learning NHibernate. Over the past few months I have been using IoC / DI (structuremap) and the repository pattern and it has made my applications much more loosely coupled and easier to test. When switching my persistence layer to NHibernate I decided to stick with my repositories. Currently I am creating a new session on each method call but of course this means that I can not benefit from lazy loading. Therefore I wish to implement session-per-request but in doing so this will make my web project dependent on NHibernate (perhaps this is not such a bad thing?). I was planning to inject ISession into my repositories and create and dispose sessions on beginrequest/endrequest events (see http://ayende.com/Blog/archive/2009/08/05/do-you-need-a-framework.aspx) Is this a good approach? Presumably I cannot use session-per-request without having a reference to NHibernate in my web project? Having the web project dependent on NHibernate prompts my next (few) questions - why even bother with the repository? Since my web app is calling services that talk to the repositories, why not ditch the repositories and just add my NHibernate persistance code inside the services? And finally, is there really any need to split out into so many projects. Is a web project and an infrastructure project sufficient? I realise that I have veered off a bit from my original question but it seems that everyone seems to have their own opinion on these topics. Some people use the repository pattern with NHibernate, some don't. Some people stick their mapping files with the related classes, others have a separate project for this. Many thanks, Ben

  • Reversed Latitude/Longitude US Tiger/Line Shape File to MySQL w/ OGR2OGRP

    - by Dave LeJeune
    Hi - I've downloaded the latest set (2010) of TIGER edge shape files (ESRI shapefile format) from the US Census website and am loading them into MySQL using the GDAL ogr2ogr utility. A new table (geotest) does get created with a SHAPE column that has the geometry defined as a LINESTRING. However, I am seeing reversed latitude and longitude values that get reversed when running the following command: ogr2ogr -f "MySQL" MySQL:"geo,user=lejeuned,host=localhost,password=cnickl234" -nln geotest -nlt LINESTRING -append -a_srs "EPSG:4326" -lco engine=MYISAM tl_2010_01021_edges.shp Mapping the latitude/longitude (after reversing them of course) they appear to be spot on so I suspect there is just something I am doing wrong or flag I am missing which is causing the latitude and longitudes to be transposed. When I select the SHAPE column using astext() I get the following result: LINESTRING(-86.69863 32.973164,-86.69853 32.97302,-86.69856 32.97287,-86.698613 32.972825,-86.6988 32.972825,-86.6989 32.972892,-86.6989 32.973002,-86.69874 32.97316,-86.69864 32.97318,-86.69863 32.973164) Any ideas what I am doing wrong?

  • UIImage from NSDocumentDirectory leaking memory

    - by Emil
    Hey. I currently have this code: UIImage *image = [[UIImage alloc] initWithContentsOfFile:[imagesPath stringByAppendingPathComponent:[NSString stringWithFormat:@"/%@.png", [postsArrayID objectAtIndex:indexPath.row]]]]; It's loading in an image to set in a UITableViewCell. This obviously leaks a lot of memory (I do release it, two lines down after setting the cells image to be that image), and I'm not sure if it caches the image at all. Is there another way, that doesen't leak so much, I can use to load in images multiple times, like in a tableView, from the Documents-directory of my app? Thanks.
