• Using jQuery for client side validation in MVC2 RTM

  - by tigermain

  Scott Gu's tutorial on Model validation gets us all set up with the MS client side validation using the following scripts: <script src="../../Scripts/jquery.validate.min.js" type="text/javascript"></script> <script src="../../Scripts/MicrosoftMvcValidation.js" type="text/javascript"></script> However I've seen various posts allowing us to utilise jQuery instead with the following code: <script src="https://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.min.js" type="text/javascript"></script> <script src="https://ajax.microsoft.com/ajax/jQuery.Validate/1.6/jQuery.Validate.min.js" type="text/javascript"></script> <script src="<%= Url.Content("~/scripts/MicrosoftMvcJQueryValidation.js") %>" type="text/javascript"></script> However MicrosoftMvcJQueryValidation.js does not ship with the solution and from what I read it should be part of the Futures pack which is no longer available on CodePlex. I managed to find a version alongside jQuery 1.3.2 but it does not work. What is the forward going solution!?

• Changing an extention method from linq-to-sql to entity framework

  - by Jova

  I'm changing my project from working with Linq-to-SQL to working with Entity Framework. I have some extention methods that extend the classes created by LINQ and I'm wondering how to change them to work with the entities instead Here's an example. public static int GetPublishedArticlesCount(this Table<Article> source) { return GetPublishedArticles(source.Context as DataContext, null).Count(); } This method gets the number of published articles. Instead of using this Table<Article>, what should I use instead?

• asp.net: deploying local resources - is embedding possible?

  - by chris

  I have an asp.net app with some local resources. These resources are used in the aspx and code-behind files: aspx: <asp:TextBox ID="TextBox1" runat="server" Text="<%$ Resources:testTag %>" /> .vb: TextBox1.Text = GetLocalResourceObject("testTag").ToString If I deploy the .resx files with the app, there are no problems. However, if I change the build action on the resx file to "Embedded Resource", the resources aren't available, even though they're in the DLL that gets built. Is it possible to deploy resources in a DLL, or am I stuck with managing & deploying resx files on the server?

• Webreference vs servicereference. Why ony one works ?

  - by phenevo

  Hi, I've got two applications. One uses webreference to my webservice, and second use servicereference to my webservice. There is metohod which I'm invoking: [WebMethod] public Car[] GetCars(string carCode) { Cars[] cars= ModelToContract.ToCars(MyFacade.GetCars(carCode); return cars; } Car has two pools: string Code {get;set;} CarType Type {get;set;} public enum CarType { Van=0, Pickup=1 } I'm debuging this webMethod, and... at the end webservice throw good collection of cars, which has one car: code="bmw",Type.Van But... Application with webrefence receives the same collection and application with servicereference gets collection, where field code is null... Invoking servicereference: MyService myService=new MyService() Cars[] cars= client.GetCars(carcode); Invoking webservice: MyService.MyServiceSoapClient client = new MyServiceS.MyServiceSoapClient(); Cars[] cars= client.GetCars(carcode);

• Override delete behaviour in NHibernate

  - by David

  Hi all In my application users cannot truly delete records. Rather, the record's Deleted field gets set to 1, which hides it from selects. I need to maintain this behaviour and I'm looking into whether NHibernate is appropriate for my app. Can I override NHibnernate's delete behaviour so that instead of issuing DELETE statements, it issues UPDATES, as described above? I would obviously also need to override its SELECT behaviour to include the 'AND Deleted = 0' clause. Or read from a view instead. I dunno. TIA for your advice. David

• JsonResult shows up a file download in browser

  - by joshb

  I'm trying to use jquery.Ajax to post data to an ASP.NET MVC2 action method that returns a JsonResult. Everything works great except when the response gets back to the browser it is treated as a file download instead of being passed into the success handler. Here's my code: Javascript: <script type="text/javascript"> $(document).ready(function () { $("form[action$='CreateEnvelope']").submit(function () { $.ajax({ url: $(this).attr("action"), type: "POST", data: $(this).serialize(), dataType: "json", success: function (envelopeData) { alert("test"); } }); }); return false; }); </script> Action method on controller: public JsonResult CreateEnvelope(string envelopeTitle, string envelopeDescription) { //create an envelope object and return return Json(envelope); } If I open the downloaded file the json is exactly what I'm looking for and the mime type is shown as application/json. What am I missing to make the jquery.ajax call receive the json returned?

• How about the Asp.net processes and threads and apppools?

  - by Michel

  Hi, as i understand, when i load a asp.net .aspx page on the (iis)server, it's processed via the w3p.exe process. But when iis gets multiple requests, are they all processed by the same w3p process? And does this process automaticly use all my processors and cores? And after that: when i start i new thread in my page, this thread still works when the pages is already served to the client. Where does this thread live? also in the w3p.exe process? And what if i assign another apppool to my site, what does that do? Michel

• JPA Cascading Delete: Setting child FK to NULL on a NOT NULL column

  - by JBristow

  I have two tables: t_promo_program and t_promo_program_param. They are represented by the following JPA entities: @Entity @Table(name = "t_promo_program") public class PromoProgram { @Id @Column(name = "promo_program_id") private Long id; @OneToMany(cascade = {CascadeType.REMOVE}) @JoinColumn(name = "promo_program_id") private List<PromoProgramParam> params; } @Entity @Table(name = "t_promo_program_param") public class PromoProgramParam { @Id @Column(name = "promo_program_param_id") private Long id; //@NotNull // This is a Hibernate annotation so that my test db gets created with the NOT NULL attribute, I'm not married to this annotation. @ManyToOne @JoinColumn(name = "PROMO_PROGRAM_ID", referencedColumnName = "promo_program_id") private PromoProgram promoProgram; } When I delete a PromoProgram, Hibernate hits my database with: update T_PROMO_PROGRAM_PARAM set promo_program_id=null where promo_program_id=? delete from t_promo_program where promo_program_id=? and last_change=? I'm at a loss for where to start looking for the source of the problem.

• How to display a new frame in an an applet?

  - by mithun1538

  Hello everyone, I have an applet. In this I have a JLabel component. When the user clicks this label, a new JFrame component gets displayed. I want to set the value of setDefaultCloseOperation() for this frame as JFrame.EXIT_ON_CLOSE. However, I get a SecurityException if I do that. I read the documentation of JFrame.EXIT_ON_CLOSE and its written that : The exit application default window close operation. If a window has this set as the close operation and is closed in an applet, a SecurityException may be thrown. It is recommended you only use this in an application. What I understood from the above is that if a frame is closed without specifying default close operation, the frame is only hidden. I want to close the frame when the user tries to close it, and not hide the frame. Is this possible?

• OpenGLES mix and match blending options complicated question

  - by DevDevDev

  So I have a background line drawing, black and white. I want to be able to draw over this, keeping the black lines in there, and drawing only where it is white. I can do this by using glBlendFunc(GL_DST_COLOR, GL_ONE_MINUS_SRC_ALPHA); And the black stays black and white gets whatever color I want. However in the white areas, I want to be able to draw some color, pick to another color and then blend. However this doesn't work because the blend function is messed up. So what I was thinking is having a linedrawing framebuffer, and a user-drawing framebuffer. The user draws into the userdrawing framebuffer, with a different blending, and then I switch blending options and draw into the linedrawing framebuffer. But i don't know enough OpenGL to say whether or not this will work or is a stupid idea. Thanks a lot

• Firing trigger for bulk insert

Presently bulk data is getting inserted into O_SALESMAN table through a stored procedure, where as the trigger is getting fired only once and O_SALESMAN_USER is having only one record inserted each time whenever the stored procedure is being executed,i want trigger to run after each and every record that gets inserted into O_SALESMAN such that both tables should have same count which is not happening..so please let me know what can be modified in this Trigger to achieve the same....

• Android - Adjust screen when keyboard pops up?

  - by Donal Rafferty

  I want to be able to adjust my UI screen on Android when the soft keyboard pops up. So at the minute I have something similiar to the first picture below where I have and EditText at the bottom of the screen and when a user taps the EditText I want the same as what happens in the second picture. That is that the EditText gets moved up and appears to "sit" on top of the soft keyboard, when the soft keyboard dissapears it should then return to its prior state. Can anyone let me know the best way to approach and implement this?

• Grails/Compass question - How can I change the compqass Connection to point to a different directory

  - by ombud

  Hi, I use the Searchable plugin with Grails I have the need to change the directory to which Compass points to, depending upon a UI choice by the user. Normally, this value is set in the compassConnection variable of the searchable map in grails-app/conf/Searchable.groovy, like so, and gets called at app startup time: searchable { compassConnection = new File( "/path/to/index/file/directory" ).absolutePath ... } To do what I need to do, I think that I need to get a handle into the compass config variable and then call config.setConnection("/new/path/to/index/dir") I don't know how I can get a reference to the config compass variable Am I right in assuming that I need to call setConnection(String) only, or is(are) there any other step(s) I need to take? Really appreciate any help that I can get, Shailen

• Is there a way to circumvent Python list.append() becoming progressively slower in a loop as the lis

  - by Deniz

  I have a big file I'm reading from, and convert every few lines to an instance of an Object. Since I'm looping through the file, I stash the instance to a list using list.append(instance), and then continue looping. This is a file that's around ~100MB so it isn't too large, but as the list grows larger, the looping slows down progressively. (I print the time for each lap in the loop). This is not intrinsic to the loop ~ when I print every new instance as I loop through the file, the program progresses at constant speed ~ it is only when I append them to a list it gets slow. My friend suggested disabling garbage collection before the while loop and enabling it afterward & making a garbage collection call. Did anyone else observe a similar problem with list.append getting slower? Is there any other way to circumvent this?

• Postgresql 8.4 reading OID style BLOBs with Hibernate

  - by peter

  I am getting this weird case when querying Postgres 8.4 for some records with Blobs (of type OIDs) with Hibernate. The query does return all right but when my code wants to read the content of the BLOB with the simple code below, it gets 0 bytes back public static byte[] readBlob(Blob blob) throws Exception { InputStream is = null; try { is = blob.getBinaryStream(); return org.apache.commons.io.IOUtils.toByteArray(is); } finally { if (is != null) try { is.close(); } catch(Exception e) {} } } Funny think is that I am getting this behavior only since I've started adding more then one such records to the table. The underlying JDBC library is type 3 (postgresq 8.4-701). Can someone give me a hint as to how to solve this issue? Thanks Peter

• Virtual Earth Shape Rendering Performance

  - by Mike

  I am overlaying a transparent image on my VEMap control by rendering it as a single VEShape. The shape changes sizes dynamically depeding on the zoom level of my map and can be as large as 4000*4000px. In older browsers such as IE6 and early versions of Firefox 2.x, map control performance degrades rapidly when my shape gets larger than 1500*1500px. The mouse pointer moves slowly and the map responds very slowly to events. I don't see this issue at all in newer browsers (IE7+). Are there any workarounds to boost performance of rendering a large shape for IE6 users?

• Getting Runtime Assemblies in Silverlight 3

  - by WoutervD

  Hello, I am currently writing a framework dll which has an AssemblyHelper. This helper stores Runtime and UserAdded assemblies to easily instantiate new objects. The .NET part of the framework uses: AppDomain MyDomain = AppDomain.CurrentDomain; Assembly[] AssembliesLoaded = MyDomain.GetAssemblies(); _runtimeAssemblies = AssembliesLoaded; This gets me all the assemblies I need. But the problem is I can't use this with Silverlight and I have no idea what to use now. Currently I am using: Assembly[] AssembliesLoaded = {Assembly.GetCallingAssembly()}; But this only adds the Assembly of my framework and not the one of the application or any other runtime assembly. What should I use? please help! Thanks in advance, Wouter

• trouble configuring WCF to use session

  - by Michael

  I am having trouble in configuring WCF service to run in session mode. As a test I wrote this simple service : [ServiceContract] public interface IService1 { [OperationContract] string AddData(int value); } [ServiceBehavior(InstanceContextMode=InstanceContextMode.PerSession)] internal class Service1 : IService1,IDisposable { private int acc; public Service1() { acc = 0; } public string AddData(int value) { acc += value; return string.Format("Accumulator value: {0}", acc); } #region IDisposable Members public void Dispose() { } #endregion } I am using Net.TCP binding with default configuration with reliable session flag enabled. As far as I understand , such service should run with no problems in session mode. But , the service runs as in per call mode - each time I call AddData , constructor gets called before executing AddData and Dispose() is called after the call. Any ideas why this might be happening?

• Math algorithm question

  - by Senica Gonzalez

  I'm not sure if this can be done without some determining factor....but wanted to see if someone knew of a way to do this. I want to create a shifting scale for numbers. Let's say I have the number 26000. I want the outcome of this algorithm to be 6500; or 25% of the original number. But if I have the number 5000, I want the outcome to be 2500; or 50% of the original number. The percentages don't have to be exact, this is just an example. I just want to have like a sine wave sort of thing. As the input number gets higher, the output number is a lower percentage of the input. Does that make sense?

• UISearchbar clearButton forces the keyboard to appear

  - by DASKAjA

  I have a UISearchBar which acts as a live filter for a table view. When the keyboard is dismissed via endEditing:, the query text and the gray circular "clear" button remain. From here, if I tap the gray "clear" button the keyboard reappears as the text is cleared. How do I prevent this? If the keyboard is not currently open I want that button to clear the text without reopening the keyboard. There is a protocol method that gets called when I tap the clear button. But sending the UISearchBar a resignFirstResponder message doesn't have any effect on the keyboard.

• Get a tableview insertRowsAtIndexPaths to accept indexOfObject?

  - by Emil

  Hey. I have a code snippet that looks like this: [tableView beginUpdates]; [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationLeft]; [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:[array indexOfObject:[array objectAtIndex:indexPath.row]]] withRowAnimation:UITableViewRowAnimationLeft]; [tableView endUpdates]; [tableView reloadData]; It gets executed when a user clicks on an accessory. The first part is only there to provide a smooth animation, and does not really matter, as the tableView is reloaded milliseconds later, but as I said, it's there to provide an animation. It is supposed to move a selected object from its current indexPath to the value from an array at the same indexPath. Obviously, this code does not work, so I just want to know what can be done to fix it? PS: I get a warning when compiling, too. The usual "passing argument 1 of 'arrayWithObject:' makes pointer from integer without a cast..." (line 3)

• ASP.NET variable scope

  - by c11ada

  hey all, im really new to ASP.Net and still havnt got my head round most of the concepts, im really having problems with variable, when creating a desktop application, any variable created in code for example int n = 10; this variable will be there until the program is running right. but in asp iv created variables which are supposed to last until the user gets of that page, so for example say i have a page which takes the users value ( call this variable n say the user type in 10) and every time the user presses the next button the code add 10 to this value. so the first time the user presses the next button n= n + 10; what i have found is no matter how many times i press the next button n will always equal 20, because the previous value is not saved !! these values are populated the first time the user enters that page, once the user clicks the next button the content of these values disappear! how can stop this from happening ?? hope this makes sense !! thanks
