• Simulating mouse clicks on Mac OSX does not work for some applications.

  - by Thomi

  Hi, I'm writing an App for Mac OSX 10.6 and later in C++. One part of theapp needs to simulate mouse movement and mouse clicks. I do this currently by posting CGEvent objects using CGEventPost(kCGHIDEventTap, event);. This works, for the msot part - I can simulate mouse movement and clicks just fine, but it seems to fail in some areas. For example: In Mozilla firefox & Safari, I can click on all the menus, but cannot click on a link within a website. When I try, the link is highlighted, but the browser never follows the link. However, I can right-click on a link, select "open link in new tab", and everything works as expected. I can click on the "Dashboard" icon to brink up the dashboard, but I cannot click on the "i" button on any of the dashboard widgets. This inconsistency is along application boundaries - Does anyone have any idea what the cause might be?

• vim command to restructure/force text to 80 columns

  - by wickedchicken

  I know there are ways to automatically set the width of text in vim using set textwidth (like http://stackoverflow.com/questions/235439/vim-80-column-layout-concerns). What I am looking for is something similar to = (the indent line command) but to wrap to 80. The use case is sometimes you edit text with textwidth and after joining lines or deleting/adding text it comes out poorly wrapped. Ideally, this command would completely reorganize the lines I select and chop off long lines while adding to short ones. An example: long line is long! short After running the command (assuming the wrap was 13 cols): long line is long! short If this isn't possible with a true vim command, perhaps there is a command-line program which does this that I can pipe the input to?

• Why trigger fired only once when running on a JQuery Object?

  - by Shlomi.A.

  Hi I got an array. I'm running over it for (i = 0; i < sugestionsArray.length; i++) { $('li.groupCode' + sugestionsArray[i] + ' span').addClass('checkedInput'); $('option[value=' + sugestionsArray[i] + ']').attr('selected', 'selected'); } And this loop runs 3 times perfectly, adding classname and playing with the option. instead of adding a clasname, i'm trying to trigger a click over the span $('li.groupCode' + sugestionsArray[i] + ' span').trigger('click'); which in his turn has a click event bind to it using jq as well Span.click(function() {}) for some reason my loop breaks after the first click. he is leaving the loop and don't continue to the next 2 loops after him. only the first span is been clicked. does anyone has an idea?

• Code optimization on minutes pr hour calculation

  - by corger

  Hi All, The following code takes a timeframe in minutes since midnight and creates an array with minutes pr hour. But, it's slow. Any better suggestions out there? (no, changing language is not an option :-) ) Const clDeparture As Long = 123 Const clArrival As Long = 233 Dim lHour As Long Dim lMinute As Long Dim alHour(25) As Long For lMinute = 0 To 1440 If lMinute >= clDeparture And lMinute < clArrival Then alHour(Int(lMinute / 60)) = alHour(Int(lMinute / 60)) + 1 End If Next The array should now contain: (0,0) (1,0) (2,57) (3,53) (4,0) .....

• HTTP Error 403.1 - Permissions are fixed, what else is wrong?

  - by baron

  I have developed a HTTP Handler Web Service, and have had it successfully deployed, through testing on other environments i've ran into another problem. This is the error message I receive: You have attempted to execute a CGI, ISAPI, or other executable program from a directory that does not allow programs to be executed. HTTP Error 403.1 - Forbidden: Execute access is denied. Internet Information Services (IIS) So it is obvious what needs to be fixed, so: 1) Start Internet Information Services (IIS) Manager. 2) Right-click the Web site that contains the SharePoint Web site that you created, and then click Properties. 3) Click the Home Directory tab. 4) Under Application settings, click either Scripts only in the Execute permissions list or Scripts and Executables in the Execute permissions list (as appropriate to your situation). Click OK. 5) Quit IIS Manager. But I'm still getting the same error. So what else could be wrong?

• iframe/lightbox refresh issues

  - by user96828

  Hi Please check out: http://gherkin.co.nz/refresh/ and click on the purple box that says 'Membership chest' You should then see some form fields in an iframe in the lightbox. If you click on the "GO" button, the page will change (currently Not found, which is fine for now). If you click the dark area to close the box, then click the purple card again - it will take you back to the not found page. When called, I want the content to always go back to the page specified in the iframe src, not the last page. Can it go back to the first specified page on this second click? Does that make sense? basically I want the iframe/lightbox to refresh its content each time it is called.

• Recursion with Func

  - by David in Dakota

  Is it possible to do recursion with an Func delegate? I have the following, which doesn't compile because the name of the Func isn't in scope... Func<long, long, List<long>, IEnumerable<long>> GeneratePrimesRecursively = (number, upperBound, primeFactors) => { if (upperBound > number) { return new List<long>(); } else { if (!primeFactors.Any(factor => number % factor == 0)) primeFactors.Add(number); return GeneratePrimesRecursively(++number, upperBound, primeFactors); // breaks here. } };

• jQuery event fires on doc ready

  - by gmcalab

  I am trying to set the click event of a button on my form and for some reason I am getting weird behavior. When I bind the click event to a function that takes no arguments, things seem to work fine. But when I bind the event with a function that takes an argument, the event fires on document ready and on click. Any ideas? Example 1: This causes an alert box to fire on ready and when the button is clicked. jQuery(document).ready(function(){ $('myButton').click(alert('foo')); }); Example 2: This causes an alert box to fire ONLY when the button is clicked. jQuery(document).ready(function(){ $('myButton').click(wrapper); }); // External js file function wrapper(){ alert('bar'); }

• How to save event handlers, when we set new html for element?

  - by Kai

  I have simple html markup: <div id="cont">Some text here <div class="wrap" style="border: 1px solid black;display: inline;"> block element here </div> and another text</div> And jQuery code: $(function(){ $(".wrap").click(function(){ $("#cont").html($("#cont").html().replace(/text/g, "letter")); alert("Click!"); }); $("#d1").click(function(){ alert("#d1 clicked!"); }); }); I expect that click event will be fire any time you clicked by the #d1 div, but when we clicked by .wrap it neve fire again. I understand why it has such behavior, but how to solve it? In my code I can't set click event for #d1 after $("#cont").html($("#cont").html().replace(/text/g, "letter")) because I don't now at execution time if event was set. You can try example on JSBin

• jQuery: How to stop propagation of a bound function not the entire event?

  - by Dale

  I have a click function bound to many elements. It is possible that sometimes these elements may sit within one another. So, the click event is bound to a child and also bound to its parent. The method is specific to the element clicked. Naturally, because of event bubbling, the child's event is fired first, and then the parents. I cannot have them both called at the same time because the parents event overwrites the event of the child. So I could use event.stopPropagation() so only the first element clicked receives the event. The problem is that there are other click events also attached to the element, for example, I am using jQuery's draggable on these elements. If I stop the propagation of the click event, then draggable doesn't work, and the following click events are not called. So my question is: Is there a way to stop the event bubbling of the method the event will call and not the entire event?

• Jquery disable link for 5 seconds

  - by John

  I have this code: $('#page-refresh').click( function() { $.ajax({ url: "/page1.php", cache: false, dataType: "html", success: function(data) { $('#pagelist').html(data); } }); return false; }); In this code is it possible that on the ajax success function it disables the #page-refresh click for 5 seconds then re-enable it? Basically if a person clicks the button and this action happens I dont want them to click and run this action again for another 5 seconds. I looked at delay() to unbind the click for this then bind it again but once it unbinded it never allowed me to click the button anymore.

• Problem with number/type of arguments passed to an overloaded c++ constructor wrapped with swig.

  - by MiKo

  I am trying to wrap a c++ class (let's call it "Spam") written by someone else with swig to expose it to Python. After solving several problems, I am able to import the module in python, but when I try to create an object of such class I obtain the following error: foo = Spam.Spam('abc',3) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "Spam.py", line 96, in __init__ this = _Spam.new_Spam(*args) NotImplementedError: Wrong number of arguments for overloaded function 'new_Spam'. Possible C/C++ prototypes are: Spam(unsigned char *,unsigned long,bool,unsigned int,SSTree::io_action,char const *) Spam(unsigned char *,unsigned long,bool,unsigned int,SSTree::io_action) Spam(unsigned char *,unsigned long,bool,unsigned int) Spam(unsigned char *,unsigned long,bool) Spam(unsigned char *,unsigned long) Googling around, I realized that the error is probably caused by the type of the arguments and not by the number (which is quite confusing), but I still cannot identify. I suspect the problem lies in passing a string as the first argument, but have no idea on how to fix it (keep in mind that I know almost no c/c++).

• ComboBox Data Binding

  - by Geertjan

  Let's create a databound combobox, levering MVC in a desktop application. The result will be a combobox, provided by the NetBeans ChoiceView, that displays data retrieved from a database: What follows is not much different from the NetBeans Platform CRUD Application Tutorial and you're advised to consult that document if anything that follows isn't clear enough. One kind of interesting thing about the instructions that follow is that it shows that you're able to create an application where each element of the MVC architecture can be located within a separate module: Start by creating a new NetBeans Platform application named "MyApplication". Model We're going to start by generating JPA entity classes from a database connection. In the New Project wizard, choose "Java Class Library". Click Next. Name the Java Class Library "MyEntities". Click Finish. Right-click the MyEntities project, choose New, and then select "Entity Classes from Database". Work through the wizard, selecting the tables of interest from your database, and naming the package "entities". Click Finish. Now a JPA entity is created for each of the selected tables. In the Project Properties dialog of the project, choose "Copy Dependent Libraries" in the Packaging panel. Build the project. In your project's "dist" folder (visible in the Files window), you'll now see a JAR, together with a "lib" folder that contains the JARs you'll need. In your NetBeans Platform application, create a module named "MyModel", with code name base "org.my.model". Right-click the project, choose Properties, and in the "Libraries" panel, click Add Dependency button in the Wrapped JARs subtab to add all the JARs from the previous step to the module. Also include "derby-client.jar" or the equivalent driver for your database connection to the module. Controler In your NetBeans Platform application, create a module named "MyControler", with code name base "org.my.controler". Right-click the module's Libraries node, in the Projects window, and add a dependency on "Explorer & Property Sheet API". In the MyControler module, create a class with this content: package org.my.controler; import org.openide.explorer.ExplorerManager; public class MyUtils { static ExplorerManager controler; public static ExplorerManager getControler() { if (controler == null) { controler = new ExplorerManager(); } return controler; } } View In your NetBeans Platform application, create a module named "MyView", with code name base "org.my.view".  Create a new Window Component, in "explorer" view, for example, let it open on startup, with class name prefix "MyView". Add dependencies on the Nodes API and on the Explorer & Property Sheet API. Also add dependencies on the "MyModel" module and the "MyControler" module. Before doing so, in the "MyModel" module, make the "entities" package and the "javax.persistence" packages public (in the Libraries panel of the Project Properties dialog) and make the one package that you have in the "MyControler" package public too. Define the top part of the MyViewTopComponent as follows: public final class MyViewTopComponent extends TopComponent implements ExplorerManager.Provider { ExplorerManager controler = MyUtils.getControler(); public MyViewTopComponent() { initComponents(); setName(Bundle.CTL_MyViewTopComponent()); setToolTipText(Bundle.HINT_MyViewTopComponent()); setLayout(new BoxLayout(this, BoxLayout.PAGE_AXIS)); controler.setRootContext(new AbstractNode(Children.create(new ChildFactory<Customer>() { @Override protected boolean createKeys(List list) { EntityManager entityManager = Persistence. createEntityManagerFactory("MyEntitiesPU").createEntityManager(); Query query = entityManager.createNamedQuery("Customer.findAll"); list.addAll(query.getResultList()); return true; } @Override protected Node createNodeForKey(Customer key) { Node customerNode = new AbstractNode(Children.LEAF, Lookups.singleton(key)); customerNode.setDisplayName(key.getName()); return customerNode; } }, true))); controler.addPropertyChangeListener(new PropertyChangeListener() { @Override public void propertyChange(PropertyChangeEvent evt) { Customer selectedCustomer = controler.getSelectedNodes()[0].getLookup().lookup(Customer.class); StatusDisplayer.getDefault().setStatusText(selectedCustomer.getName()); } }); JPanel row1 = new JPanel(new FlowLayout(FlowLayout.LEADING)); row1.add(new JLabel("Customers: ")); row1.add(new ChoiceView()); add(row1); } @Override public ExplorerManager getExplorerManager() { return controler; } ... ... ... Now run the application and you'll see the same as the image with which this blog entry started.

• Play 2.0 javaToDo tutorial doesn't compile

  - by chsn

  I'm trying to follow the Play2.0 JavaToDO tutorial and for some reason it just doesn't want to work. Have looked through stackoverflow and other online resources, but haven't find an answer to this and it's driving me crazy. Attached code of the Application.java package controllers; import models.Task; import play.data.Form; import play.mvc.Controller; import play.mvc.Result; public class Application extends Controller { static Form<Task> taskForm = form(Task.class); public static Result index() { return redirect(routes.Application.tasks()); } public static Result tasks() { return ok( views.html.index.render(Task.all(), taskForm)); } public static Result newTask() { return TODO; } public static Result deleteTask(Long id) { return TODO; } } Attached code of the Task java package models; import java.util.List; import javax.persistence.Entity; import play.data.Form; import play.data.validation.Constraints.Required; import play.db.ebean.Model.Finder; import play.mvc.Result; import controllers.routes; @Entity public class Task { public Long id; @Required public String label; // search public static Finder<Long,Task> find = new Finder( Long.class, Task.class); // display tasks public static List<Task> all() { return find.all(); } // create task public static void create(Task task) { task.create(task); } // delete task public static void delete(Long id) { find.ref(id).delete(id); // find.ref(id).delete(); } // create new task public static Result newTask() { Form<Task> filledForm = taskForm.bindFromRequest(); if(filledForm.hasErrors()) { return badRequest( views.html.index.render(Task.all(), filledForm) ); } else { Task.create(filledForm.get()); return redirect(routes.Application.tasks()); } } } I get a compile error on Task.java on the line static Form<Task> taskForm = form(Task.class); As I'm working on eclipse (the project is eclipsified before import), it's telling me that taskForm cannot be resolved and it also underlines every play 2 command e.g. "render(), redirect(), bindFromRequest()" asking me to create a method for it. Any ideas how to solve the compilations error and also how to get Eclipse to recognize the play2 commands? EDIT: updated Application.java package controllers; import models.Task; import play.data.Form; import play.mvc.Controller; import play.mvc.Result; public class Application extends Controller { // create new task public static Result newTask() { Form<Task> filledForm = form(Task.class).bindFromRequest(); if(filledForm.hasErrors()) { return badRequest( views.html.index.render(Task.all(), filledForm) ); } else { Task.newTask(filledForm.get()); return redirect(routes.Application.tasks()); } } public static Result index() { return redirect(routes.Application.tasks()); } public static Result tasks() { return ok( views.html.index.render(Task.all(), taskForm)); } public static Result deleteTask(Long id) { return TODO; } } Updated task.java package models; import java.util.List; import javax.persistence.Entity; import play.data.Form; import play.data.validation.Constraints.Required; import play.db.ebean.Model; import play.db.ebean.Model.Finder; import play.mvc.Result; import controllers.routes; @Entity public class Task extends Model { public Long id; @Required public String label; // Define a taskForm static Form<Task> taskForm = form(Task.class); // search public static Finder<Long,Task> find = new Finder( Long.class, Task.class); // display tasks public static List<Task> all() { return find.all(); } // create new task public static Result newTask(Task newTask) { save(task); } // delete task public static void delete(Long id) { find.ref(id).delete(id); // find.ref(id).delete(); } }

• Ext.Button handler config option

  - by ppecher

  someClass = Ext.extend(someClassB, { _someFunctionC{ someButton = new Ext.button({ handler: function () { this._onClick('click'); } }), _onClick(someMessage){ Ext.Msg.alert(someMessage); } } } _onClick eats one parameter; in the above code you put in the 'click' event because you want _onClick to be executed after the user clicks on the button. However, how do you specify this specific 'click' registration AND pass in a local variable as the _onClick parameter at the same time? As an aside, why do you even have to specify 'click', when the API states that handler always pertains to a click? Is this additional information not unnecessary?

• how to kill an older jsonp request?

  - by pfg

  I have a cross-domain long polling request using getJSON with a callback that looks something like this: $.getJSON("http://long-polling.com/some.fcgi?jsoncallback=?" function(data){ if(data.items[0].rval == 1) { // update data in page } }); The problem is the request to the long-polling service might take a while to return, and another getJSON request might be made in the meantime and update the page even though it is a stale response. Req1: h**p://long-polling.com/some.fcgi at 10:00 AM Req2: h**p://long-polling.com/some.fcgi? at 10:01 AM Req1 returns and updates the data on the page 10:02 AM I want a way to invalidate the return from Req1 if Req2 has already been made. Thanks!
