• Migrating VseWss project to WspBuilder

  - by Khurram Aziz

  I have a VseWss project that I want to migrate to WspBuilder. The project has many features (Content Types, Fields, Lists, Event Listeners, Workflows, ASPX files, their code behind etc) and the project references couple of other assemblies as well. And it does the SafeControls entries and deploys the assemblies into GAC etc Important aspect is; the WSP that gets created from the VseWss is deployed to the production server and while migrating I want to preserve all of these things so that when I create the WSP from WspBuilder things are transparent for the Sharepoint Administrators. Please guide me how to proceed...any online tutorial or related stuff that talks about migrating a real world VseWss project (with 10-20 different types of features)

• Options for keeping models and the UI in sync (in a desktop application context)

  - by Benju

  In my experience I have only had 2 patterns work for large-scale desktop application development when trying to keep the model and UI in sync. 1-An eventbus approach via a shared eventbus command objects are fired (ie:UserDemographicsUpdatedEvent) and have various parts of the UI update if they are bound to the same user object updated in this event. 2-Attempt to bind the UI directly to the model adding listeners to the model itself as needed. I find this approach rather clunky as it pollutes the domain model. Does anybody have other suggestions? In a web application with something like JSP binding to the model is easy as you ussually only care about the state of the model at the time your request comes in, not so in a desktop type application. Any ideas?

• Fast single thread comet server, possible?

  - by Pepijn

  I recently encountered a few cases where a server would distribute an event stream that contains the exact same data for all listeners, such as a 'recent activity' box. It occurred to me that it is quite strange and inefficient to have a server like Apache run a thread processing and querying the database for every single comet stream containing the same data. What I would do for those global(not per user) streams is run a single thread that continuously emits data, and a new (green)thread for every new request that outputs the headers and then 'merges' into the main thread. Is it possible for one thread to serve multiple sockets, or for multiple clients to listen to the same socket? An example o = event # threads received | a b # 3 o / / # 3 - |/_/ | # 1 o c # 2 a, b | / o/ # 2 a, b o # 1 a, b, c | # connection b closed o # 1 a, c Does something like this exist? Would it work? Is it possible to do? Disclaimer: I'm not a server expert.

• How to catch mousewheel up/down event using RaphaelJs

  - by alex.dominte

  I need to implement a horizontal scrollable timeline. I've drawn the timeline/grids/rulers etc. I just need to catch mousewheel up/down to scroll the timeline (backward - past/forward - future). First I need to catch the event: but nothing I've found seems to work. Need browser support only for chrome/firefox (latest versions). These 2 won't listeners won't work: var paper = new Raphael('raphael-paper'); // ... paper.canvas.on('mousewheel', function(event) { console.log(event); }); // ... paper.canvas.addEventListener('mousewheel', function(event) { console.log(event); });

• Resize Ext.form.ComboBox to fit its content

  - by ITRushn

  There are quite few solutions on Ext forums, but I wasn’t able to get any of them work. It seems I am missing something minor. I need to resize combobox to fit its content when it’s first created. I do not need to worry about resizing it when content is changing. Is there any working examples using Extjs 3.2? Current Code: var store = new Ext.data.ArrayStore({ fields: ['view', 'value', 'defaultselect'], data: Ext.configdata.dataCP }); comboCPU = new Ext.form.ComboBox({ tpl: '<tpl for="."><div class="x-combo-list-item"><b>{view}</b><br /></div></tpl>', store: store, displayField: 'view', width: 600, typeAhead: true, forceSelection: true, mode: 'local', triggerAction: 'all', editable: false, emptyText: 'empty text', selectOnFocus: true, listeners: { select: AdjustPrice, change: AdjustPrice, beforeselect: function (combo, record, index) { return ('false' == record.data.disabled); } }, applyTo: 'confelement' }); I've also tried removing width: 600 and replacing it with minListWidth: 600 but that result following and didnt fix the issue.

• Create iPhone app programmatically, in its entirety

  - by miorel

  I recently became interested in iPhone app development, so I've been looking at online tutorials, and also reading a book, trying out the examples as I go along. I'm getting better, but one of the things I still find quite annoying about the usual development model is that I really have no idea what the SDK is really doing behind the scenes to make the app "work" because Apple protects me from this. For example, when I make connections on interface builder, this presumably corresponds to code being generated somewhere... Where that code is and what it does and how it works are not obvious (to me). So I'm wondering, is it possible to create an iPhone app entirely programmatically? That is, have execution start in some main method, which will then programmatically create any views, register event listeners, etc. And if yes, what are some good resources for something like this?

• Where's all the XPCOM user documentation?

  - by Graham Paulson

  Google can't find much user documentation for XPCOM. Sure, it can find endless references to making new XPCOM components in C++, but that's utterly useless to anyone who needs to know how to use the existing components from JavaScript. This is a huge gap, occasionally touched on by trivial examples of creating an instance and calling a method. Has nobody with a more in-depth knowledge of the componentry written anything about its use? Using components with multiple interfaces? Implementing listeners for handling asynchronous behaviour? "Rapid Application Development with Mozilla" is no help (great breadth but little depth). Spotty references that exist to the defunct XULPlanet redirect to Mozilla Development Center, but that's pretty useless. Mozilla Development Center articles point back to XULPlanet, which is a joke. Is this the best an army of open source advocates can muster to promote the extension of The Beast?

• Android Class which extends Dialog, how to clear TextViews before it is displayed

  - by wuntee

  I have a class that extends android.app.Dialog, the layout is done in an xml file, and the setup (button listeners, etc) is done on the onCreate method. My problem is that whenever the dialog is displayed, then dismissed, and displayed again, the Editable TextViews are still populated with the information that was displayed previously. What is the common way to clear these text fields? Remember - this is a separate class that extends Dialog - so there is no 'onDialogCreate' like Activity has. Or, perhaps I am extending the wrong class? There is just a lot of processing being done, and do not want to have all the code in the main Activity. I would like it to be in a separate Class. I tried to extend AlertDialog, but it does not create the border like Dialog does. Any help would be great. The dialog is shown via the Activity: protected Dialog onCreateDialog(int id) { switch(id){ case DIALOG_NEW_SAFE: return(new NewSafeDialog(this)); default: return(null); } }

• How is it possible to get the forms mouseposition when clicking inside a control?

  - by ikky

  Hi. I have a panel and have added a PictureBox to it. I have added mouse_click listeners to both the panel and the picturebox. When they are clicked i create a messagebox which tells me the mouse position. Problem: When i click the panel, i get the mouse position i want. When i click the pictureBox, i get the current position in that picturebox. What i want: I want both of the controls to get the current mouseposition on the form. I can also go with getting the current mouseposition of the panel, since it is overlaying the form. Does anybody know how i can do this? I've googled around for this, but can't seem to find anything about it. Thank you in advance.

• Javax Swing Timer Help

  - by kap

  Hello Guys, I am having some problems concerning starting javax.swing.Timer after a mouse click. I want to start the timer to perform some animation after the user clicks on a button but it is not working. Here are the code snippets: public class ShowMe extends JPanel{ private javax.swing.Timer timer; public ShowMe(){ timer = new javax.swing.Timer(20, new MoveListener()); } // getters and setters here private class MoveListener implements ActionListener { public void actionPerformed(ActionEvent e) { // some code here to perform the animation } } } This is the class which contains a button so that when the user clicks on the button the timer starts to begin the animation public class Test{ // button declarations go here and registering listeners also here public void actionPerformed(ActionEvent e) { if(e.getSource() == this.btnConnect){ ShowMe vis = new ShowMe(); vis.getTimer().start(); } } } I want to start the timer to begin the animation but it is not working. Need help how to make a timer start after button click. Thanks.

• extjs4 display tooltip on button click instead of mouse hover

  - by user856753

  I am trying to add a on click listener to the below tooltip. I do not want the tooltip to display on mouse hover. Instead it need it show on button click. Do I have to add a handler function inside a listener? { xtype: 'button', cls:'my-btn', iconCls:'question', src:'../www/css/slate/btn/question.png', padding: '5 0 0 0', listeners: { render: function(cmp) { Ext.create('Ext.tip.ToolTip', { closable:true, hideDelay : 3000, padding: '0 0 0 0', maxWidth:400, width:800, target: cmp.el, html: "<b>read-only</b>:Users will have read only access to all pages", getTargetXY: function() { return [810, 340]; } }); } } },

• Accessing E4X nodes having special characters in name without breaking binding chain in flex.

  - by Jonas

  I am using E4X to bind some values from xml in flex 3. There is a problem when xml tag's (or attribute's) name has special character in it: having xml content var xml:XML = <tag> <special-name att="val" /> </tag> special-name could not be accessed using xml.special-name.@att because it is interpreted as subtraction, on the other hand using square bracket notation xml['special-name'].@att breaks binding chain. Is there an elegant way to solve this (like special language syntax) without writing custom binding setters and listeners?

• Java anonymous class efficiency implications

  - by Po

  Is there any difference in efficiency (e.g. execution time, code size, etc.) between these two ways of doing things? Below are contrived examples that create objects and do nothing, but my actual scenarios may be creating new Threads, Listeners, etc. Assume the following pieces of code happen in a loop so that it might make a difference. Using anonymous objects: void doSomething() { for (/* Assume some loop */) { final Object obj1, obj2; // some free variables IWorker anonymousWorker = new IWorker() { doWork() { // do things that refer to obj1 and obj2 } }; } } Defining a class first: void doSomething() { for (/* Assume some loop */) { Object obj1, obj2; IWorker worker = new Worker(obj1, obj2); } } static class Worker implements IWorker { private Object obj1, obj2; public CustomObject(Object obj1, Object obj2) {/* blah blah */} @Override public void doWork() {} }; Thank you :)

• itemdoubleclick event in ExtJS Charts

  - by Abdel Olakara

  Hi all, I got a strange issue today while working on ExtJS charts. I am trying to use some of the events for the chart when user clicks on the chart items. I found the following events are available: itemclick, itemdoubleclick, itemdrag, itemdragstart, itemdragend, itemmouseover, itemmouseout Here is my test chart where I have implemented all these events. Each event just create a list tag in my debuging console. The issue is, no matter what, itemdoubleclick do not get fired! what is the issue? Why is it not getting fired? xtype:'columnchart', width:600, height:350, id:'myChart', store: store, xField: 'month', yField: 'sales', listeners: { itemdoubleclick: function(o) { var dh = Ext.DomHelper; dh.append('consoleList', {tag: 'li', html: 'itemdoubleclick'}); } } In firebug console, I see that this event is registered. PS: In my code above, I have put only the event that is not working. Thanks in advance for your ideas and suggestions.

• addEventListener gone after appending innerHTML

  - by Vishal Shah

  Okay, so i have the following html added to a site using javascript/greasemonkey. (just sample) *a id='abc'*HEllo*/a* *a id='xyz'*Hello*/a* (excuse me, i've had to replace the '<' '' with * since hyperlinks for new users aren't allowed!) and i've also added a click event listener for the elements. All works fine up to this point, the click event gets fired when i click the element. But... i have another function in the script, which upon a certain condition, modifies that html, ie it appends it, so it looks like: *a id='abc'*HEllo*/a* *a id='xyz'*Hello*/a* *a id='123'*Hello*/a* but when this is done, it breaks the listeners i added for the first two elements... nothing happens when i click them. if i comment out the call to the function which does the appending, it all starts working again! help please...

• EXT JS toLayout on Viewport doesnt show anything...

  - by Nazariy

  After reading many example about adding new components in to existing container without reloading whole page I run in to small problem while combining tree and tabs inside Viewport component. What I'm trying to do is to register on click event to tree node and load in to content container new component, depending on node type it can be tabpanel, gridpanel or any other available component. here is short example of tree object: { xtype: 'treepanel', id: 'tree-panel', listeners: { click: function(n) { var content = Ext.getCmp('content-panel'); content.setTitle(n.attributes.qtip); //remove all components from content-panel content.removeAll(); content.add(dummy_tabs2); content.doLayout(); return; } }} All DOM manipulation went fine, everything registered properly, new Title shown, but dummy_tabs2 are not shown. I did try to set various properties for doLayout(true|false, true|false) but nothing happens. Am I doing something wrong?

• Making your class an event source in Java

  - by Crystal

  I'm making a custom button in Java that has two states, mousePressed, and mouseReleased. At the same time, if I wanted to reuse this button, so that other event listeners can register with it, are these the appropriate steps I should do: override addActionListener(ActionListener action) override removeActionListener(ActionListener action) have a private variable like List <ActionListener> list = new List <ActionListener>() to keep track of when events get added and some sort of function with for loop to run all the actions: public void runListeners() { for (ActionListener al : list) { al.actionPerfomed; } } I'm not really sure if this is the way you can do it or if there are other things I am missing. Like does my custom class have to be implements ActionListener? Thanks.

• Data-separation in a Symfony Multi-tenant app using Doctrine

  - by Prasad

  I am trying to implement a multi-tenant application, that is - data of all clients in a single database - each shared table has a tenant_id field to separate data I wish to achieve data separation by adding where('tenant_id = ', $user->getTenantID()) {pseudoc-code} to all SELECT queries I could not find any solution up-front, but here are possible approaches I am considering. 1) crude approach: customizing all fetchAll and fetchOne functions in every class (I will go mad!) 2) using listeners: possibly coding for the preDqlSelect event and adding the 'where' to all queries 3) override buildQuery(): could not find an example of this for front-end 4) implement contentformfilter: again need a pointer Would appreciate if someone could validate these & comment on efficieny, suitability. Also, if anyone has achieved multitenancy using another strategy, pl share. Thanks

• Is ActiveMQ unreliable?

  - by user122991

  Hello, We have been using ActiveMQ 5.2 in our distributed enterprise application for about 3 months. During that time, we have experienced debilitating failures at least twice weekly. In particular, we see: 1) Topic publisher has its connection arbitrarily closed and experiences EOF on attempt to publish. Note well that this issue is not a function of some timeout. It does not correlate reliably with any inactivity. 2) Queue listeners never receive message. Message simply sits on Queue. 2) is much rarer (hardly ever) than 1). In both cases, the failures are highly intermittent-- they cannot be reliably reproduced through any testing usage pattern. Also, there are no errors or warning in the AMQ logs. Have others experienced similar problems? Is there an opinion that some other JMS provider is more reliable? thanks, Joe

• GF 3.0.1 + Virtual Server: www.myhost.com:8080/projectname-war => www.myhost.com. How?

  - by Harry Pham

  EDIT I need to change www.myhost.com:8080/myproject-war to www.myhost.com. Here is what I've been trying: I configurate the Virtual Server: server. I have still have default Network Listeners to be http-listener-1 and http-listner-2. I change the Default Web Module to ScholarActive#ScholarActive-war.war (The only option in the drop down list, since I only deploy 1 application). For the docroot, I try this ${com.sun.aas.instanceRoot}/applications/ScholarActive/ScholarActive-war_war or this ${com.sun.aas.instanceRoot}/applications/ScholarActive/ Both does not work. What does docroot need to point to, for this to work? what I try to do is: when I type localhost:8080/ScholarActive-war, then my application load, I want to make so that if I type locahost:8080, it will load the app as well, then what left is changed the port to 80. But no luck. Any Idea?

• How can I separate Logic/UI in Android

  - by Ungureanu Liviu

  Hi, I want as my application to be structured in 2 parts: the logic code and the UI. I've tried to implement that using a controller class(here I keep the logic code) inside of each activity. The activity send messages to controller and receive the answer in two ways: the answer is returned immediately (if the action is not complex and it can be done in a verry short time) the activity set some listeners and the controller fire this listener when the action is complete. The problems appears when the controller have a lot of objects(each object should handle a set of actions and for each action I have to set & trigger a listener): it is hard to keep the code syncronized. I'm asking if you know a better way to implement this mechanism. Thank you.

• preventing window blur/focusOut when selecting copy/paste menu

  - by jedierikb

  I am trying to determine when the user has moved focus out of the browser to: select copy/paste (but not to the google search box). Ffox handles this nicely. selecting another window/tab/external widget (e.g., the google search box). focusOut and blur listeners on window and document cannot seem to disambiguate between these two types of focus changes. Can IE do this? I want this distinction so that I can better support usability in my web app without losing focus.

• different small js files per page VS. 1x site-wide js file?

  - by Haroldo

  Different pages of my site have different js needs (plugins mainly), some need a lightbox, some dont, some need a carousel, some dont etc. With regards to pageloading speed should i option 1 - reference each js file when it is needed: so one page might have: <script type="text/javascript" src="js/carousel/scrollable.js"></script> <script type="text/javascript" src="js/jquery.easydrag.js"></script> <script type="text/javascript" src="js/colorbox/jquery.colorbox-min.js"></script> and another have: <script type="text/javascript" src="st_wd_assets/js/carousel/scrollable.js"></script> <script type="text/javascript" src="st_wd_assets/js/typewatch.js"></script> option 2 - combine and compress into one site_wide.js file: so each page would reference: <script type="text/javascript" src="js/site_wide.js"></script> there would be unused selectors/event listeners though, how bad is this? I would include any plugin notes/accreditations at the top of the site_wide.js file

• Databinding in windows forms on an object graph with possible null properties?

  - by Fredrik

  If I have an object graph like this: class Company { public Address MainAddress {...} } class Address { public string City { ... } } Company c = new Company(); c.MainAddress = new Address(); c.MainAddress.City = "Stockholm"; and databind to a control using: textBox1.DataBinding.Add( "Text", c, "MainAddress.City" ); Everything is fine, but If I bind to: Company c2 = new Company(); c2 using the same syntax it crashes since the MainAddress property is null. I wonder if there is a custom Binding class that can set up listeners for all the possible paths here and bind to the actual object dynamically when/if I sometime later in the application set the MainAddress property.
