  • QtScript: Passing an array of objects to C++

    - by Plow
    Hi, I want to pass an array of objects from my QtScript to C++ but I have not been able to figure out how to achieve this. As soon as I create an array, the elements inside it are converted to strings before I can access them. This is what I have been trying so far: class myObject : public QObject, public QScriptable { Q_OBJECT public Q_SLOTS: void test(QVariantList list); }; void myObject::test(QVariantList list) { for (QVariantList::const_iterator it = list.begin(); it != list.end(); ++it) { QVariant element = *it; qDebug() << "List element type: " << element.typeName(); if (element.canConvert<QVariantMap>()) { // Not getting here } } } The following script myObject.test([{"foo": 1, "bar": 2}, {"baaz": 3, "baaaz": 4}]); prints List element type: "QString" List element type: "QString" I am using Qt 4.6...

  • Test if single linked list is circular by traversing it only once

    - by user1589754
    I am a fresher and I was asked this question in a recent interview I gave. The question was --- By traversing each element of linked list just once find if the single linked list is circular at any point. To this I answered that we will store reference of each node while traversing the list in another linked list and for every node in the list being tested we will find if the reference exists in the list I am storing the references. The interviewer said that he needs a more optimized way to solve this problem. Can anyone please tell me what would be a more optimized method to solve this problem.

  • Swapping UIImages causing 'unrecognized selector sent to instance' ?

    - by user158103
    Error: [__NSCFDate drawAtPoint:]: unrecognized selector sent to instance 0xd251e0 Termininating app due to uncaught exception 'NSInvalidArgumentException' Scenario: for the most part this works. But I notice this error, even on the simulator, when I swapping UIImages, slowly, but consistently. For example, I have a retained reference to a UIImage that im drawing. By the click of a picker control I am changing the face image (this occurs in another view-controller). I can consistently recreate this error by continuously changing the faces. It usually crashes at about the 4th swap or more. My theory: It's not loading the image, therefore the image reference is nil. I know ive read a bit about UIImage being cached, so I wouldnt think im running out of memory. Any ideas? Thanks!

  • Fleunt NHibernate not working outside of nunit test fixtures

    - by thorkia
    Okay, here is my problem... I created a Data Layer using the RTM Fluent Nhibernate. My create session code looks like this: _session = Fluently.Configure(). Database(SQLiteConfiguration.Standard.UsingFile("Data.s3db")) .Mappings( m => { m.FluentMappings.AddFromAssemblyOf<ProductMap>(); m.FluentMappings.AddFromAssemblyOf<ProductLogMap>(); }) .ExposeConfiguration(BuildSchema) .BuildSessionFactory(); When I reference the module in a test project, then create a test fixture that looks something like this: [Test] public void CanAddProduct() { var product = new Product {Code = "9", Name = "Test 9"}; IProductRepository repository = new ProductRepository(); repository.AddProduct(product); using (ISession session = OrmHelper.OpenSession()) { var fromDb = session.Get<Product>(product.Id); Assert.IsNotNull(fromDb); Assert.AreNotSame(fromDb, product); Assert.AreEqual(fromDb.Id, product.Id); } My tests pass. When I open up the created SQLite DB, the new Product with Code 9 is in it. the tables for Product and ProductLog are there. Now, when I create a new console application, and reference the same library, do something like this: Product product = new Product() {Code = "10", Name = "Hello"}; IProductRepository repository = new ProductRepository(); repository.AddProduct(product); Console.WriteLine(product.Id); Console.ReadLine(); It doesn't work. I actually get pretty nasty exception chain. To save you lots of head aches, here is the summary: Top Level exception: An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail.\r\n\r\n The PotentialReasons collection is empty The Inner exception: The IDbCommand and IDbConnection implementation in the assembly System.Data.SQLite could not be found. Ensure that the assembly System.Data.SQLite is located in the application directory or in the Global Assembly Cache. If the assembly is in the GAC, use element in the application configuration file to specify the full name of the assembly. Both the unit test library and the console application reference the exact same version of System.Data.SQLite. Both projects have the exact same DLLs in the debug folder. I even tried copying SQLite DB the unit test library created into the debug directory of the console app, and removed the build schema lines and it still fails If anyone can help me figure out why this won't work outside of my unit tests it would be greatly appreciated. This crazy bug has me at a stand still.

  • Creating BlackBerry method stubs using wscompile on WSDL from ColdFusion

    - by Jim B
    I have been working on a BlackBerry application that consumes web services from ColdFusion 7. The Java ME SDK and the Java Wireless Toolkit both require that the generated WSDL be of the document/literal type. Fortunately, I have input on the web service development so I tried setting 'style="document"' in the cfcomponent tag. This generated a document/literal style WSDL but now wscompile generates the following errors in several places: Found unknown simple type: javax.xml.soap.SOAPElement Found unknown simple type: java.util.Calendar Any ideas why this is happening? The WSDL does get parsed correctly by the JWSDP tool but the stubs use namespaces that are not available in the J2ME platform. I would have thought ColdFusion WSDL would work more easily with other products in the Java family.

  • Writing from an array to a file bash and new lines

    - by S1syphus
    I'm trying to write a script the generates a template file for Pashua (a perl script for creating GUI on osx) I want to crate an instance for each item in the array, so the ideal output would be: AB1.type = openbrowser AB1.label = Choose a master playlist file AB1.width=310 AB1.tooltip = Blabla filesystem browser AB2.type = openbrowser AB2.label = Choose a master playlist file AB2.width=310 AB2.tooltip = Blabla filesystem browser ...and so on for the rest of the array: What I am using to write to the text file at the moment is: count=1 saveIFS="$IFS" IFS=$'\n' array=($(<TEST.txt)) IFS="$saveIFS" for i in "${array[@]}"; do declare AD$count="$i"; ((count++)); done for i in "${array[@]}"; do echo "AD$count".type = openbrowser "AD$count".label = Choose a master playlist file \n "AD$count".width=310 \n "AD$count".tooltip = Blabla filesystem browser \n" >> long.txt; done However \n doesn't produce a newline in the text file, and I am pretty sure there is a alot nicer way todo this, ideas?

  • MVC 3 Remote Validation jQuery error on submit

    - by Richard Reddy
    I seem to have a weird issue with remote validation on my project. I am doing a simple validation check on an email field to ensure that it is unique. I've noticed that unless I put the cursor into the textbox and then remove it to trigger the validation at least once before submitting my form I will get a javascript error. e[h] is not a function jquery.min.js line 3 If I try to resubmit the form after the above error is returned everything works as expected. It's almost like the form tried to submit before waiting for the validation to return or something. Am I required to silently fire off a remote validation request on submit before submitting my form? Below is a snapshot of the code I'm using: (I've also tried GET instead of POST but I get the same result). As mentioned above, the code works fine but the form returns a jquery error unless the validation is triggered at least once. Model: public class RegisterModel { [Required] [Remote("DoesUserNameExist", "Account", HttpMethod = "POST", ErrorMessage = "User name taken.")] [Display(Name = "User name")] public string UserName { get; set; } [Required] [Display(Name = "Firstname")] public string Firstname { get; set; } [Display(Name = "Surname")] public string Surname { get; set; } [Required] [Remote("DoesEmailExist", "Account", HttpMethod = "POST", ErrorMessage = "Email taken.", AdditionalFields = "UserName")] [Display(Name = "Email address")] public string Email { get; set; } [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 8)] [DataType(DataType.Password)] [Display(Name = "Password")] public string Password { get; set; } [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 8)] [DataType(DataType.Password)] [Display(Name = "Confirm password")] public string ConfirmPassword { get; set; } [Display(Name = "Approved?")] public bool IsApproved { get; set; } } public class UserRoleModel { [Display(Name = "Assign Roles")] public IEnumerable<RoleViewModel> AllRoles { get; set; } public RegisterModel RegisterUser { get; set; } } Controller: // POST: /Account/DoesEmailExist // passing in username so that I can ignore the same email address for the same user on edit page [HttpPost] public JsonResult DoesEmailExist([Bind(Prefix = "RegisterUser.Email")]string Email, [Bind(Prefix = "RegisterUser.UserName")]string UserName) { var user = Membership.GetUserNameByEmail(Email); if (!String.IsNullOrEmpty(UserName)) { if (user == UserName) return Json(true); } return Json(user == null); } View: <script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script> <script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.8.17/jquery-ui.min.js" type="text/javascript"></script> <script type="text/javascript" src="/Content/web/js/jquery.unobtrusive-ajax.min.js"></script> <script type="text/javascript" src="/Content/web/js/jquery.validate.min.js"></script> <script type="text/javascript" src="/Content/web/js/jquery.validate.unobtrusive.min.js"></script> ...... @using (Html.BeginForm()) { @Html.AntiForgeryToken() <div class="titleh"> <h3>Edit a user account</h3> </div> <div class="body"> @Html.HiddenFor(model => model.RegisterUser.UserName) @Html.Partial("_CreateOrEdit", Model) <div class="st-form-line"> <span class="st-labeltext">@Html.LabelFor(model => model.RegisterUser.IsApproved)</span> @Html.RadioButtonFor(model => model.RegisterUser.IsApproved, true, new { @class = "uniform" }) Active @Html.RadioButtonFor(model => model.RegisterUser.IsApproved, false, new { @class = "uniform" }) Disabled <div class="clear"></div> </div> <div class="button-box"> <input type="submit" name="submit" value="Save" class="st-button"/> @Html.ActionLink("Back to List", "Index", null, new { @class = "st-clear" }) </div> </div> } CreateEdit Partial View @model Project.Domain.Entities.UserRoleModel <div class="st-form-line"> <span class="st-labeltext">@Html.LabelFor(m => m.RegisterUser.Firstname)</span> @Html.TextBoxFor(m => m.RegisterUser.Firstname, new { @class = "st-forminput", @style = "width:300px" }) @Html.ValidationMessageFor(m => m.RegisterUser.Firstname) <div class="clear"></div> </div> <div class="st-form-line"> <span class="st-labeltext">@Html.LabelFor(m => m.RegisterUser.Surname)</span> @Html.TextBoxFor(m => m.RegisterUser.Surname, new { @class = "st-forminput", @style = "width:300px" }) @Html.ValidationMessageFor(m => m.RegisterUser.Surname) <div class="clear"></div> </div> <div class="st-form-line"> <span class="st-labeltext">@Html.LabelFor(m => m.RegisterUser.Email)</span> @Html.TextBoxFor(m => m.RegisterUser.Email, new { @class = "st-forminput", @style = "width:300px" }) @Html.ValidationMessageFor(m => m.RegisterUser.Email) <div class="clear"></div> </div> Thanks, Rich

  • Multiple Controls on a Page with Multiple Instances of Javascript

    - by mattdell
    I have created a Web Control in ASP for use in integrating with Telligent CommunityServer. The control is written in ASP with some 10 lines of C# backend for controlling visibility of the UI elements based on permissions, but I'd say 90% of the functionality is straight-up Javascript. The control works beautifully, until you drop two instances of the Control on the same page--since they reference the exact same Javascript functions, only one control works. How can I take this functionality that I have, this 1200 lines of Javascript, and make it so that each instance of the control can reference its each unique instance of Javascript?

  • Table/column names enclosed in square brackets, even though their names consist of legal characters

    - by AspOnMyNet
    Square brackets allow you to use names for columns or aliases that contain characters not permitted for column names or aliases. a) I’ve noticed that lots of times table and column names are enclosed inside square brackets, even though their names consist of perfectly legal characters. Why is that? b) As far as I know, square brackets enclosing object’s name aren’t actually a part of that name. Thus, if we create a table named [A]: CREATE TABLE [A] ( … ) we can later reference it without using brackets: SELECT * FROM A But why isn’t the same true when I try to reference a column KEY from a table returned by CONTAINSTABLE function? Namely, if I omit the brackets enclosing column name, I get an error: SELECT ct.KEY FROM CONTAINSTABLE(fullText,*,'some_string') as ct thanx

  • Why an input button created dynamically through a literal tag doesn't work ?

    I have created button 2 below: <input id="Button1" type="button" value="Stop" onclick="alert('hello world');"/> <input id="Button2" type="button" value="button" OnClik="alert('hello world');"/> using a litteral tag on page load like this: protected void Page_Load(object sender, EventArgs e) { Literal1.Text = "<input id=\"Button2\" type=\"button\" value=\"button\" OnClik=\"alert('hello world');\"/>"; } Incredibly when testing in browser, click on button 1 works, not click on button 2 whereas the codes are the same ! Am I missing something ?

  • OpenCMS - Best approach for showing rotating references

    - by user197127
    Hi, I would like to add on the right column of my site a rotating references section. Each reference would have some text + name of person + company name. It does not need to be structured (open text is also ok). I would then want opencms to rotate between 20 difference references each time a page is displayed. I can keep a session scope counter holding which reference we last showed. I need a way to manage the references (users not programmers) over time. My question is which would be the best way to do so? Thanks

  • WCF reuse types in referenced assemblies does not reuse the ServiceContract Interface

    - by Matt
    I have three seperate projects: -MyUserControl (Needs a reference to a service implementing IMyService) -MyService (Implements IMyService) -MySharedInterfaces (IMyUserControl and IMyService) -MyWebApp The user control needs to be dynamically loaded at runtime. This implements IMyUserControl and has a property of type IMyService which will be set at runtime. The trouble is even with the option to reuse types the WebApp isn't reusing the IMyServiceType, it always generates it again from the Service Reference. This wouldn't be an issue if I could cast it to MySharedInterfaces.IMyService (which I can't understand, since it should be exactly the same). The user control is expecting something of type IMyService, is there anyway to either cast the WebServiceReference.IMyService back to MySharedInterface.IMyServiceReference or force the WebServiceReference to reuse the MySharedInterface.IMyServiceReference? Thanks

  • Is it possible to define a virtual directory in IIS and make the files relative to the physical dire

    - by Mikey John
    Is it possible to define a virtual directory in IIS and somehow make the files in that directory relative to the physical directory and not to the virtual directory ? For instance on my server I have the following folders: D:\WebSite\Css\myTheme.css, D:\WebSite\Images\image1.jpg I created a virtual directory on IIS resources.mysite: Inside my website I reference the sheet like this resources.mysite/myTheme.css But inside myTheme.css I reference pictures from ../Images/images1.jpg. So the problem is that image1.jpg is not found because it is relative to the physical folder and not the virtual folder on IIS. Can I solve this problem without modifying the style sheet ?

  • Tornado Web & Persistent Connections

    - by Engrost
    How can I write Http server in TornadoWeb that will support persistent Connections. I mean will be able to receive many requests and answer to them without closing connection. How does it actually work in async? I just want to know how to write handler to handle persistent connection. How actually would it work? I have handler like that: class MainHandler(RequestHandler): count = 0 @asynchronous def post(self): #get header content type content_type = self.request.headers.get('Content-Type') if not content_type in ACCEPTED_CONTENT: raise HTTPError(403, 'Incorrect content type') text = self.request.body self.count += 1 command = CommandObject(text, self.count, callback = self.async_callback(self.on_response)) command.execute() def on_response(self, response): if response.error: raise HTTPError(500) body = response.body self.write(body) self.flush() execute calls callback when finishes. is my asumption right that with things that way post will be called many times and for one connection count will increase with each httprequest from client? but for each connection I will have separate count value?

  • java checked exception in a catch clause compilation error

    - by srandpersonia
    Hi, I was expecting an compilation error in the following program because of the throw statement in the catch block as IOException is a checked exception and it is not caught by another try block within the catch block. But I am getting "Hurray!" printed. Any explanation would be much appreciated. According to JLS 11.2.3, http://java.sun.com/docs/books/jls/third_edition/html/exceptions.html It is a compile-time error if a method or constructor body can throw some exception type E when both of the following hold: * E is a checked exception type * E is not a subtype of some type declared in the throws clause of the method or constructor. import java.io.*; public class Test{ public static void main(String args[]) { System.out.println(method()); } public static int method() { try{ throw new Exception(); } catch(Exception e){ throw new IOException(); //No compile time error } finally{ System.out.println("Hurray!"); } } } Thanks in advance.

  • Haskell: What is the difference between $ (dollar) and $! (dollar exclamation point)

    - by Jelle Fresen
    Can anybody explain the difference in Haskell between the operators ($) and ($!) (dollar sign vs dollar sign exclamation point)? I haven't seen the use of $! anywhere so far, but while browsing through the Haskell reference on www.zvon.org, I noticed its existence and that it has the exact same definition as $. When trying some simple statements in a Haskell interpreter (ghci), I couldn't find any difference, nor could I find any reference to the operator in the top listed tutorials when googling for haskell tutorial. So, just out of curiosity, what is the difference, if at all?

  • PostgreSQL - best way to return an array of key-value pairs

    - by Matt W
    I'm trying to select a number of fields, one of which needs to be an array with each element of the array containing two values. Each array item needs to contain a name (character varying) and an ID (numeric). I know how to return an array of single values (using the ARRAY keyword) but I'm unsure of how to return an array of an object which in itself contains two values. The query is something like SELECT t.field1, t.field2, ARRAY(--with each element containing two values i.e. {'TheName', 1 }) FROM MyTable t I read that one way to do this is by selecting the values into a type and then creating an array of that type. Problem is, the rest of the function is already returning a type (which means I would then have nested types - is that OK? If so, how would you read this data back in application code - i.e. with a .Net data provider like NPGSQL?) Any help is much appreciated.

  • Good conventions for embedding schema of a flat file

    - by Ville Koskinen
    We receive lots of data as flat files: delimitted or just fixed length records. It's sometimes hard to find out what the files actually contain. Are there any well established practices for embedding the schema of the file to the beginning or the end of a file to make the file self-explanatory? Just to get an idea, imagine something like this: <data name=test records=2 type=fixed> <field name=foo start=0 length=2 type=numeric> <field name=bar start=2 length=4 type=text> </data> 11test 12ing We would parse the xml in the beginning and use it for reading the records.

  • Why won't IsChecked change on this toggle button?

    - by cjroebuck
    I have the following xaml for a toggle button: <ToggleButton Margin="0,3" Grid.Row="3" Grid.ColumnSpan="2" Command="{Binding DataContext.SelectAllCommand, Mode=OneWay, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}"> <ToggleButton.Style> <Style TargetType="{x:Type ToggleButton}"> <Setter Property="Content" Value="Select All"/> <Style.Triggers> <Trigger Property="IsChecked" Value="True"> <Setter Property="Content" Value="Select None"/> <Setter Property="Command" Value="{Binding DataContext.SelectNoneCommand, Mode=OneWay, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}"/> </Trigger> </Style.Triggers> </Style> </ToggleButton.Style> </ToggleButton> But the IsChecked property never gets updated when clicking the button. If I use snoop and force the IsChecked to True then the trigger kicks in.

  • ProviderException: InvalidCastException

    Few of our clients are regularly getting invalid cast exception, with variations i.e. InvalidCastException / ProviderException, but both generating from method call: System.Web.Security.SqlRoleProvider.GetRolesForUser(String username) The other variation is: Exception type: InvalidCastException Exception message: Unable to cast object of type System.Int32 to type System.String. I had a look at application event log which shows: Stack trace: at System.Web.Security.SqlRoleProvider.GetRolesForUser(String username) at System.Web.Security.RolePrincipal.IsInRole(String role) at System.Web.Configuration.AuthorizationRule.IsTheUserInAnyRole(StringCollection roles, IPrincipal principal) at System.Web.Configuration.AuthorizationRule.IsUserAllowed(IPrincipal user, String verb) at System.Web.Configuration.AuthorizationRuleCollection.IsUserAllowed(IPrincipal user, String verb) at System.Web.Security.UrlAuthorizationModule.OnEnter(Object source, EventArgs eventArgs) at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)* Has anyone come across this issue, and if so what is the fix? Thanks JS

    - by Tom
    Hi, i get the webpage content from an external website using ajax but now i want a function which extract a specific input field value which is already autofilled. the webpage content is like this: ......... <input name="fullname" id="fullname" size="20" value="David Smith" type="text"> <input name="age" id="age" size="2" value="32" type="text"> <input name="income" id="income" size="20" value="22000$" type="text"> ......... I only want to get the value of fullname, maybe with some javascript regex, or some jQuery dom parser, i know i can do it easily with php but i want it using Javascript or jQuery. Note: this inputs are not hosted in my page, they are just pulled from other website through Ajax. Thanks
