  • UX question: is better to have "serious delete" or have "trash"

    - by ftrotter
    I am developing an application that allows for a user to manage some individual data points. One of the things that my users will want to do is "delete" but what should that mean? For a web application is it better to present a user with the option to have serious delete or to use a "trash" system? Under "serious delete" (would love to know if there is a better name for this...) you click "delete" and then the user is warned "this is final and tragic action. Once you do this you will not be able to get -insert data point name here- back, even if you are crying..." Then if they click delete... well it truly is gone forever. Under the "trash" model, you never trust that the user really wants to delete... instead you remove the data point from the "main display" and put into a bucket called "the trash". This gets it out of the users way, which is what they usually want, but they can get it back if they make a mistake. Obviously this is the way most operating systems have gone. The advantages of "serious delete" are: Easy to implement Easy to explain to users The disadvantages of "serious delete" are: it can be tragically final sometimes, cats walk on keyboards The advantages of the "trash" system are: user is safe from themselves bulk methods like "delete a bunch at once" make more sense saves support headaches The disadvantages of the "trash" system are": For sensitive data, you create an illusion of destruction users think something is gone, but it is not. Lots of subtle distinctions make implementation more difficult Do you "eventually" delete the contents of the trash? My question is which one is the right design pattern for modern web applications? With enough discussion to justify your answer... Would love to be pointed towards some relevant research. -FT

  • What should be the responsibility of a presenter here?

    - by Achu
    I have a 3 layer design. (UI / BLL / DAL) UI = ASP.NET MVC In my view I have collection of products for a category. Example: Product 1, Product 2 etc.. A user able to select or remove (by selecting check box) product’s from the view, finally save as a collection when user submit these changes. With this 3 layer design how this product collection will be saved? How the filtering of products (removal and addition) to the category object? Here are my options. (A) It is the responsibility of the controller then the pseudo Code would be Find products that the user selected or removed and compare with existing records. Add or delete that collection to category object. Call SaveCategory(category); // BLL CALL Here the first 2 process steps occurs in the controller. (B) It is the responsibility of BLL then pseudo Code would be Collect products what ever user selected SaveCategory(category, products); // BLL CALL Here it's up to the SaveCategory (BLL) to decide what products should be removed and added to the database. Thanks

  • GWT dev mode throws ArrayIndexOutOfBoundsException when compile GinjectorImpl.java

    - by Jiang Zhu
    I'm getting following exception when open my GWT app in development mode. the exact same code can compile successfully using mvn gwt:compile Caused by: java.lang.ArrayIndexOutOfBoundsException: 3667 at com.google.gwt.dev.asm.ClassReader.readClass(ClassReader.java:1976) at com.google.gwt.dev.asm.ClassReader.accept(ClassReader.java:464) at com.google.gwt.dev.asm.ClassReader.accept(ClassReader.java:420) at com.google.gwt.dev.shell.rewrite.HasAnnotation.hasAnnotation(HasAnnotation.java:45) at com.google.gwt.dev.shell.CompilingClassLoader.findClass(CompilingClassLoader.java:1100) at com.google.gwt.dev.shell.CompilingClassLoader.loadClass(CompilingClassLoader.java:1203) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:247) at com.google.gwt.dev.shell.ModuleSpace.loadClassFromSourceName(ModuleSpace.java:665) at com.google.gwt.dev.shell.ModuleSpace.rebindAndCreate(ModuleSpace.java:468) at com.google.gwt.dev.shell.GWTBridgeImpl.create(GWTBridgeImpl.java:49) at com.google.gwt.core.shared.GWT.create(GWT.java:57) at com.google.gwt.core.client.GWT.create(GWT.java:85) at ...

  • How to hide check all, clear all checkbox

    - by Kalpana
    I am having check box in the column header. The function of this is to check or uncheck all the check boxes in that column.If the row check box is checked and say delete, that row can be deleted from the dataTable. If the row object is used in some other table as a foreign key i put '-' in that row instead of check box which indicates that row cannot be deletable. In these cases if all the row has '-" , there is no need to have the header check box. How to programatically hide this 'Check All | Clear All' check box, if there is nothing to be removed. It would be even preferable to hide the 'Remove' button if there is no selection to be made. What are the best practices to address the above scenario. I have attached the javascript which I am using. <script type="text/javascript"> var tableId = '#user\\:userList'; jQuery(document).ready(function() { jQuery('#selectAll').click(function() { jQuery(tableId).find("input[type='checkbox']").attr('checked', jQuery('#selectAll').is(':checked')); }); }); </script>

  • Detect if any USB drive is detected or not using WinForm Application in Visual C#

    - by Pavan Kumar
    I want to do the following things in my application 1) I want to display whether any USB drive is inserted or not in my application to prompt the user to insert a USB drive. I just want to notify the user if any USB dirve is inserted else prompt him to insert one using a label or something (i want to avoid messagebox as it will keep appearing whenever a device is inserted or removed. It will be irritating for the end user) in my Visual C# WinForm Application. If any USB drive is present display "USB drive detected" in the label. The user may add one or more USB sticks but the status will remain same. When there is none then the status of the label will change to "No USB drives found.Please insert a USB drive". 2) When one or more USB drive is added the volume name with the drive letter for example "James(F:)" is added to the Combobox list. The combobox list also needs to remove the entry for the USB drive added in the list automatically when it is removed . So when there is no USB the list should be empty and the label will again prompt user to insert a USB stick or drive.

  • jQuery Autocomplete plugin (Jorn Zaefferer's) - how to dynamically change the list of displayed valu

    - by Max Williams
    I'm using Jorn Zaefferer's Autocomplete query plugin, http://bassistance.de/jquery-plugins/jquery-plugin-autocomplete/ I have options set so it shows all the values when you click in the empty text field, a bit like a select, and the option is also set so that the user can only choose from the list of values used by the autocomplete (so it's kind of like a select but with autocomplete functionality). I have two radio buttons below the text field, which determine whether the user chooses from a long list or a short list of possible values. I want to update the values used in the autocomplete when one of these radio buttons is clicked. Currently i'm doing this in a not very clever way by calling autocomplete again on the same text field, with the different array of values, but this creates a situation where both are active at once, and i can see the long list peeking out from behind the short list. What i need to do is either a) dynamically change the values used in the autocomplete or b) remove (unbind?) the autocomplete from the text field before re-initialising it. Either of these would do tbh though option a) is kind of nicer. Any ideas anyone? Here's my current code: function initSubjectLongShortList(field, short_values, long_values){ $(".subject_short_long_list").change(function(){ updateSubjectAutocomplete(field, short_values, long_values); }); updateSubjectAutocomplete(field, short_values, long_values); } function updateSubjectAutocomplete(field, short_values, long_values){ if($(".subject_short_long_list:checked").attr('id') == "subject_long_list"){ initSubjectAutocomplete(field, long_values); } else { initSubjectAutocomplete(field, short_values); } } function initSubjectAutocomplete(field, values){ jQuery(field).autocomplete(values, { minChars: 0, //make it appear as soon as we click in the field max: 2000, scrollHeight: 400, matchContains: true, selectFirst: false }); } cheers, max

  • Problem with extended ASCII characters in web page/master page

    - by Oyvind Brathen
    I have some localization problems in my webpage. There are basically two problems (that I suspect have a different sulution, but they are conseptually linked) First problem is this: I have a website that is using a master page. All text from the page is fine, but all text that comes from the master page file, get scrambled norwegian characters. For example Ø shows up as Ø. It seems that all characthers in the extended ASCII table gets scrambled this way. Afterwards, if I open the master page in Notepad the Ø looks normal, but if I remove the Ø and write a new Ø manually, then save the file from Notepad, and then open the website in the browser, it looks fine and the Ø is shown properly. So it seems that Visual Studio saves the characters wrongly in the master file, but correct for the aspx file. Any clue here? The second issue is norwegian characters coming from jQuery. All of these characters get's replaced by a questionmark with a black box around it. Here, modifying the js file in Notepad does not help, and it still display scrambled in the browser. Any input here would be appreciated.

  • .Except<T> is throwing an Exception

    - by Jason
    I have the following code: Public Shared Function GetAvailableManufacturers() As List(Of Manufacturer) 'first get all the live orders and extract their mfrs' Dim sos As List(Of OrderForm) = GetFormsByStatus(StockStatus.Building) Dim unavailableMfrs As New List(Of Manufacturer) For Each so As StockingOrder In sos unavailableMfrs.Add(so.Source) Next 'then remove all mfrs with an open SO from a list of all mfrs' Dim allMfrs As List(Of Manufacturer) = Manufacturer.GetManufacturers Return allMfrs.Except(unavailableMfrs) <----- error here End Function Explanation of what the above does: GetFormsByStatus() self-explanatory GetManufacturers() returns a list of all manufacturers in the database My idea to get available manufacturers was to get a list of all the manufacturers in my open forms, then get a list of all manufacturers and exclude all the manufacturers in the first list, illustrated like so (pseudo): List A: {1,2,3,4,5,6,7,8,9,10} List B: {5,7,10} Result: {1,2,3,4,6,8,9} I have set up my Manufacturer class according to this article so that it can be compared, but I'm still getting this error: Unable to cast object of type '<ExceptIterator>d__92'1[csCore.Manufacturer]' to type 'System.Collections.Generic.List'1[csCore.Manufacturer]'. I thought at first that because during testing GetFormsByStatus() returns 0 results maybe that was causing problems, but it doesn't make sense that Except() wouldn't work if the provided list had 0 items. Can anyone spot what I'm doing wrong? Thanks so much!

  • jQuery AJAX call not working in Webkit

    - by Brian
    I've run into a strange issue with Webkit based browsers (both Safari and Chrome - I'm testing on a Mac) and I am not sure what is causing it. Here's a small script I've created that replicates the issue: <html> <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript" language="javascript"> function doRequest() { document.test.submit(); $.ajax({ type: "GET", cache: false, url: 'ajax.php?tmp=1', success: doSuccess }); } function doSuccess(t_data,t_status,req) { alert('Data is: '+ t_data +', XMLHTTPRequest status is: '+ req.status); } </script> </head> <body> <form name="test" method="post" action="ajax.html" enctype="multipart/form-data"> <input type="file" name="file_1"> <br><input type="button" value="upload" onclick="doRequest();"> </form> </body> </html> ajax.php is: <?php echo $_REQUEST['tmp']; ?> This works as is on Firefox, but the XMLHTTPRequest status is always "0" on both Safari and Chrome. If I remove this line: document.test.submit(); then it works, but of course the form is not submitted. I've tried changing the form submit button from "button" to "submit", but that also prevents it from working on Safari or Chrome. What I am trying to accomplish is: submit the form call another script to get status on the file being uploaded via the form (it's for a small upload progress meter). Any help is really appreciated - I'm hopeful it is just a quirk I'm not familiar with. Thanks! Brian

  • MySQL Full-Text Search Across Multiple Tables - Quick/Long Solution?

    - by Kerry
    Hello all, I have been doing a bit of research on full-text searches as we realized a series of LIKE statements are terrible. My first find was MySQL full-text searches. I tried to implement this and it worked on one table, failed when I was trying to join multiple tables, and so I consulted stackoverflow's articles (look at the end for a list of the ones I've been to) I didn't see anything that clearly answered my questions. I'm trying to get this done literally in an hour or two (quick solution) but I also want to do a better long term solution. Here is my query: SELECT a.`product_id`, a.`name`, a.`slug`, a.`description`, b.`list_price`, b.`price`, c.`image`, c.`swatch`, e.`name` AS industry FROM `products` AS a LEFT JOIN `website_products` AS b ON (a.`product_id` = b.`product_id`) LEFT JOIN ( SELECT `product_id`, `image`, `swatch` FROM `product_images` WHERE `sequence` = 0) AS c ON (a.`product_id` = c.`product_id`) LEFT JOIN `brands` AS d ON (a.`brand_id` = d.`brand_id`) INNER JOIN `industries` AS e ON (a.`industry_id` = e.`industry_id`) WHERE b.`website_id` = 96 AND b.`status` = 1 AND b.`active` = 1 AND MATCH( a.`name`, a.`sku`, a.`description`, d.`name` ) AGAINST ( 'ashley sofa' ) GROUP BY a.`product_id` ORDER BY b.`sequence` LIMIT 0, 9 The error I get is: Incorrect arguments to MATCH If I remove d.name from the MATCH statement it works. I have a full-text index on that column. I saw one of the articles say to use an OR MATCH for this table, but won't that lose the effectiveness of being able to rank them together or match them properly? Other places said to use UNIONs but I don't know how to do that properly. Any advice would be greatly appreciated. In the idea of a long term solution it seems that either Sphinx or Lucene is best. Now by no means and I a MySQL guru, and I heard that Lucene is a bit more complicated to setup, any recommendations or directions would be great.

  • Annotation to make available generic type

    - by mdma
    Given an generic interface like interface DomainObjectDAO<T> { T newInstance(); add(T t); remove(T t); T findById(int id); // etc... } I'd like to create a subinterface that specifies the type parameter: interface CustomerDAO extends DomainObjectDAO<Customer> { // customer-specific queries - incidental. } The implementation needs to know the actual template parameter type, but of course type erasure means isn't available at runtime. Is there some annotation that I could include to declare the interface type? Something like @GenericParameter(Customer.class) interface CustomerDAO extends DomainObjectDAO<Customer> { } The implementation could then fetch this annotation from the interface and use it as a substitute for runtime generic type access. Some background: This interface is implemented using JDK dynamic proxies as outlined here. The non-generic version of this interface has been working well, but it would be nicer to use generics and not have to create a subinterface for each domain object type. The actual type is needed at runtime to implement the newInstance method, amongst others.

  • Stack and Hash joint

    - by Alexandru
    I'm trying to write a data structure which is a combination of Stack and HashSet with fast push/pop/membership (I'm looking for constant time operations). Think of Python's OrderedDict. I tried a few things and I came up with the following code: HashInt and SetInt. I need to add some documentation to the source, but basically I use a hash with linear probing to store indices in a vector of the keys. Since linear probing always puts the last element at the end of a continuous range of already filled cells, pop() can be implemented very easy without a sophisticated remove operation. I have the following problems: the data structure consumes a lot of memory (some improvement is obvious: stackKeys is larger than needed). some operations are slower than if I have used fastutil (eg: pop(), even push() in some scenarios). I tried rewriting the classes using fastutil and trove4j, but the overall speed of my application halved. What performance improvements would you suggest for my code? What open-source library/code do you know that I can try?

  • Run unittest in a Class

    - by chrissygormley
    Hello, I have a test suite to perform smoke tests. I have all my script stored in various classes but when I try and run the test suite I can't seem to get it working if it is in a class. The code is below: (a class to call the tests) from alltests import SmokeTests class CallTests(SmokeTests): def integration(self): self.suite() if __name__ == '__main__': run = CallTests() run.integration() And the test suite: class SmokeTests(): def suite(self): #Function stores all the modules to be tested modules_to_test = ('external_sanity', 'internal_sanity') alltests = unittest.TestSuite() for module in map(__import__, modules_to_test): alltests.addTest(unittest.findTestCases(module)) return alltests if __name__ == '__main__': unittest.main(defaultTest='suite') So I can see how to call a normal function defined but I'm finding it difficult calling in the suite. In one of the tests the suite is set up like so: class InternalSanityTestSuite(unittest.TestSuite): # Tests to be tested by test suite def makeInternalSanityTestSuite(): suite = unittest.TestSuite() suite.addTest(TestInternalSanity("BasicInternalSanity")) suite.addTest(TestInternalSanity("VerifyInternalSanityTestFail")) return suite def suite(): return unittest.makeSuite(TestInternalSanity) If I have def suite() inside the class SmokeTests the script executes but the tests don't run but if I remove the class the tests run. I run this as a script and call in variables into the tests. I do not want to have to run the tests by os.system('python tests.py'). I was hoping to call the tests through the class I have like any other function. This need's to be called from a class as the script that I'm calling it from is Object Oriented. If anyone can get the code to be run using Call Tests I would appreciate it alot. Thanks for any help in advance.

  • 'Must Override a Superclass Method' Errors after importing a project into Eclipse

    - by Tim H
    Anytime I have to re-import my projects into Eclipse (if I reinstalled Eclipse, or changed the location of the projects), almost all of my overridden methods are not formatted correctly, causing the error 'The method ?????????? must override a superclass method'. It may be noteworthy to mention this is with Android projects - for whatever reason, the method argument values are not always populated, so I have to manually populate them myself. For instance: list.setOnCreateContextMenuListener(new OnCreateContextMenuListener() { public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { //These arguments have their correct names } }); will be initially populated like this: list.setOnCreateContextMenuListener(new OnCreateContextMenuListener() { public void onCreateContextMenu(ContextMenu arg1, View arg2, ContextMenuInfo arg3) { //This methods arguments were not automatically provided } }); The odd thing is, if I remove my code, and have Eclipse automatically recreate the method, it uses the same argument names I already had, so I don't really know where the problem is, other then it auto-formatting the method for me. This becomes quite a pain having to manually recreate ALL my overridden methods by hand. If anyone can explain why this happens or how to fix it .. I would be very happy. Maybe it is due to the way I am formatting the methods, which are inside an argument of another method?

  • Understanding floating point problems

    - by Maxim Gershkovich
    Could someone here please help me understand how to determine when floating point limitations will cause errors in your calculations. For example the following code. CalculateTotalTax = function (TaxRate, TaxFreePrice) { return ((parseFloat(TaxFreePrice) / 100) * parseFloat(TaxRate)).toFixed(4); }; I have been unable to input any two values that have caused for me an incorrect result for this method. If I remove the toFixed(4) I can infact see where the calculations start to lose accuracy (somewhere around the 6th decimal place). Having said that though, my understanding of floats is that even small numbers can sometimes fail to be represented or have I misunderstood and can 4 decimal places (for example) always be represented accurately. MSDN explains floats as such... This means they cannot hold an exact representation of any quantity that is not a binary fraction (of the form k / (2 ^ n) where k and n are integers) Now I assume this applies to all floats (inlcuding those used in javascript). Fundamentally my question boils down to this. How can one determine if any specific method will be vulnerable to errors in floating point operations, at what precision will those errors materialize and what inputs will be required to produce those errors? Hopefully what I am asking makes sense.

  • Why can't I use WCF DataContract and ISerializable on the same class?

    - by Dave
    Hi all, I have a class that I need to be able to serialize to a SQLServer session variable and be available over a WCF Service. I have declared it as follows namespace MyNM { [Serializable] [DataContract(Name = "Foo", Namespace = "http://www.mydomain.co.uk")] public class Foo : IEntity, ISafeCopy<Foo> { [DataMember(Order = 0)] public virtual Guid Id { get; set; } [DataMember(Order = 1)] public virtual string a { get; set; } DataMember(Order = 2)] public virtual Bar c { get; set; } /* ISafeCopy implementation */ } [Serializable] [DataContract(Name = "Bar ", Namespace = "http://www.mydomain.co.uk")] public class Bar : IEntity, ISafeCopy<Bar> { #region Implementation of IEntity DataMember(Order = 0)] public virtual Guid Id { get; set; } [DataMember(Order = 1)] public virtual Baz y { get; set; } #endregion /* ISafeCopy implementation*/ } [Serializable] [DataContract] public enum Baz { [EnumMember(Value = "one")] one, [EnumMember(Value = "two")] two, [EnumMember(Value = "three")] three } But when I try and call this service, I get the following error in the trace log. "System.Runtime.Serialization.InvalidDataContractException: Type 'BarProxybcb100e8617f40ceaa832fe4bb94533c' cannot be ISerializable and have DataContractAttribute attribute." If I take out the Serializable attribute, the WCF service works, but when the object can't be serialized to session. If I remove the DataContract attribute from class Bar, the WCF service fails saying Type 'BarProxy3bb05a31167f4ba492909ec941a54533' with data contract name 'BarProxy3bb05a31167f4ba492909ec941a54533:http://schemas.datacontract.org/2004/07/' is not expected. Add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer I've tried adding a KnownType attribute to the foo class [KnownType(typeof(Bar))] But I still get the same error. Can anyone help me out with this? Many thanks Dave

In current browsers, I am able to do this by creating a DOM element, adding the selected text, appending the copyright text and then selecting the new node: var newSelection = document.createElement( 'div' ); newSelection.style.cssText = "height: 1px; width: 1px; overflow: hidden;"; if( window.getSelection ) { var selection = window.getSelection( ); if( selection.getRangeAt ) { var range = selection.getRangeAt( 0 ); newSelection.appendChild( range.cloneContents( ) ); appendCopyright( ); document.body.appendChild( newSelection ); selection.selectAllChildren( newSelection ); // ... remove element, return selection } } In IE9, this errors out on the selection.selectAllChildren( newSelection ) statement and I was able to figure out that this is because newSelection was effectively "hidden" from the viewport due to the styles applied in the second line above. Commenting that out works, but obviously the new node is shown to the end user. It appears that this was resolved in later versions of IE, but I am having trouble coming up with a workaround that is sufficient for IE9, a browser that I need to support. I've tried a variety of alternatives, like setting visibility: hidden;, positioning it off-screen, and trying some alternative selection functions, but they each present different problems. The error thrown by IE is: SCRIPT16389: Unspecified error.

  • jQuery Validation Plugin: Invoke errorPlacement function when onfocusout, keyup and click

    - by th3hamburgler
    Hi, I am using the jquery validation plugin and want to use the errorPlacement function to add error messages to the fields title attribute and display just a ? next to the field. This works great when the form is submitted with the submit button but when any of the following events are triggered: - onfocusout - click - onkeyup The validation checks are run but it skips the errorPlacement function and adds the full error message after the field, like the default behaviour. I am using the following code: $("#send-mail").validate({ debug: true, // set this class to error-labels to indicate valid fields success: function(label) { // set text as tick label.html("&#10004;").addClass("valid"); }, // the errorPlacement has to take the table layout into account errorPlacement: function(error, element) { console.log("errorPlacement called for "+element.attr("name")+" field"); // check for blank/success error if(error.text() == "") { // remove field title/error message from element element.attr("title", ""); console.log("error check passed"); } else { // get error message var message = error.text(); // set as element title element.attr("title", message); // clear error html and add cross glyph error.html("&#10008;"); console.log("error check failed: "+message); } // add error label after form element error.insertAfter(element); }, ignoreTitle: true, errorClass: "invalid" });

  • Jquery Form ajaxSubmit not submitting

    - by Gazler
    Hi, I am using the JQuery Form extension to submit a form with AJAX. I have the following code: var options = { beforeSubmit: showRequest, // pre-submit callback success: showResponse, // post-submit callback // other available options: //url: url // override for form's 'action' attribute //type: 'post', // 'get' or 'post', override for form's 'method' attribute //dataType: null // 'xml', 'script', or 'json' (expected server response type) clearForm: true, // clear all form fields after successful submit //resetForm: true // reset the form after successful submit // $.ajax options can be used here too, for example: timeout: 3000 }; $('#composeForm').submit(function() { // inside event callbacks 'this' is the DOM element so we first // wrap it in a jQuery object and then invoke ajaxSubmit $(this).find(':disabled').removeAttr('disabled'); $(this).ajaxSubmit(options); // !!! Important !!! // always return false to prevent standard browser submit and page navigation return false; }); The problem is that the form doesn't appear to be submitting, or atleast the success function is not being called. If I remove the return false, then the submission works, but the page navigates away. Is there a problem in my code that could be causing this? Cheers, Gazler.

  • HTTPService/ResultEvent with Flex 3.2 versus Flex >= 3.5

    - by Julian
    Hey everybody, through a design decission or what-so-ever Adobe changed the content of the ResultEvent fired by a HTTPService Object. Take a look at following example: var httpService:HTTPService = myHTTPServices.getResults(); httpService.addEventListener(ResultEvent.RESULT,resultHandler); httpService.send(); /** * Handels the login process */ function resultHandler(event:ResultEvent):void { // get http service var httpService = (event.target as HTTPService); // do something } It works like a charm with Flex 3.2. But when I try to compile it with Flex 3.5 or Flex 4.0 event.target as HTTPService is null. I figured out that event.target is now an instance of HTTPOperation. That is interesting because I can't find HTTPOperation in the langref. However, I think what Flash Builder's debugger means is mx.rpc.http.Operation. The debugger also shows that event.target has a private attribute httpService which is the instance I expected to get with event.target. But it's private, so event.target.httpService doesn't work. If I only want to remove the EventListener I can cast event.target as EventDispatcher. But I need to use methods from HTTPService. So: How can I get the HTTPService instance from the ResultEvent? Any help would be appreciated. Thanks! J.

  • Using a profile property of type List in .NET Membership

    - by hancock
    Hi, I'm working on a C# Webservice that needs to provide authentication as well as roles and profile management. I need each profile to have a property of type List. The profile section in the web.config looks like this: <profile defaultProvider="MyProfileProvider" enabled="true"> <providers> <remove name="MyProfileProvider"/> <add connectionStringName="MySqlServer" applicationName="MyApp" name="MyProfileProvider" type="System.Web.Profile.SqlProfileProvider" /> </providers> <properties> <add name="Websites" type="System.Collections.Generic.List&lt;String&gt;" serializeAs="Binary"/> </properties> </profile> However, when I start the webservice and try to access that property it returns the following error: System.Configuration.ConfigurationErrorsException: Attempting to load this property's type resulted in the following error: Could not load type 'System.Collections.Generic.List<String>'. (C:\Projects\MyProject\web.config line 58) --- System.Web.HttpException: Could not load type 'System.Collections.Generic.List<String>'. Is there a way to use a generic collection for this purpose?

  • Using jQuery and AJAX works for all functions except one, really bizarre issue (from my perspective)

    - by CoreyT
    I am working on a classic asp form that has a number of dropdowns. Three of these are cascading, i.e. they rely in the previous dropdown. For almost everything this code works fine, one of them however is not playing nice. To start off I have a script tag with the following in it: $(document).ready(function () { $("#AcademicLevel").change(getList); $("#CourseDeliveryTime").change(updateLocation); $("#ProgramType").change(updateEntryTerm); }); This works just fine for the first two elements of the form, AcademicLevel and CourseDeliveryTime, the third however does not take effect however. If I use Firebug's Console and run that same line of code, $("#ProgramType").change(updateEntryTerm);, it starts to work, sort of. What happens is what confuses me. If the function it is pointing to, updateEntryTerm, has an alert() call in it, it works. If the alert is commented out, it does not work. The function is below: function updateEntryTerm() { $.ajax({ type: "POST", url: "../Classic ASP and AJAX/jQueryExample.asp", dataType: "application/x-www-form-urlencoded", data: "Action=UpdateEntryTerm&acadLevel=" + $("#AcademicLevel").val() + "&courseTime=" + $("#CourseDeliveryTime").val() + "&programType=" + $("#ProgramType").val(), async: false, success: function (msg) { $("#EntryTerm").remove(); $("#tdEntryTerm").append(msg); //alert(msg); } //, //error: function (xhr, option, err) { // alert("XHR Status: " + xhr.statusText + ", Error - " + err); //} }); } I am lost on two different issues here, First why is the call to $("#ProgramType").change(updateEntryTerm); not working unless I run it in Firebug Console? Second, why does the function itself, updateEntryTerm, not work unless the alert() call is present? Has anyone seem something like this before?
