  • Symfony 2 - UrlGenerator::doGenerate is called before listener

    - by guyaloni
    I want to add to the context a parameter, so when login is called I can use it in the route (similar to _locale). I can add this piece of code in HttpUtils.php (as resetLocale), but i don't find it very clean. The reason I need it is the firewall redirection to the login controller, which I would like to have in its route a customized parameter. My problem is that my listener is called after UrlGenerator::doGenerate is called, so I get a MissingMandatoryParametersException. Here is my config.yml relevant code: services: mycompany.demobundle.listener.request: class: MyCompany\DemoBundle\RequestListener arguments: [@router, @security.context] tags: - { name: kernel.event_listener, event: kernel.request, method: onKernelRequest } Any idea???

  • How to keep the popup menu of a JComboBox open on populating it ?

    - by Stormshadow
    I have a JComboBox on my Panel. One of the popup menu items is 'More' and when I click that I fetch more menu items and add them to the existing list. After this, I wish to keep the popup menu open so that the user realizes that more items have been fetched however, the popup closes. The event handler code I am using is as follows public void actionPerformed(ActionEvent e) { if (e.getSource() == myCombo) { JComboBox selectedBox = (JComboBox) e.getSource(); String item = (String) selectedBox.getSelectedItem(); if (item.toLowerCase().equals("more")) { fetchItems(selectedBox); } selectedBox.showPopup(); selectedBox.setPopupVisible(true); } } private void fetchItems(JComboBox box) { box.removeAllItems(); /* code to fetch items and store them in the Set<String> items */ for (String s : items) { box.addItem(s); } } I do not understand why the showPopup() and setPopupVisible() methods are not functioning as expected.

  • Is Webhooks a style/pattern or a specification?

    - by Emilio
    I've been reading about Webhooks and I'm trying to determine if it's a specification vs a style/pattern. By "specification" I mean that the implementation details, e.g. headers, payload and so on are well defined. By "style" or "pattern" I mean in the sense that REST is a style (as opposed to a spec) or a pattern which describes usage but doesn't define implementation details. From what I see, Webhooks is a style/pattern. That the event(s) which triggers the http callbacks are generated however the developer wants, and that the http callbacks have no specific implementation requirements except to be an http post. Is this correct?

  • Performance problem Loading Dataset inside a virtual.

    - by ShaneH
    Host Configuration: HP EliteBook 8530w 4G Ram Win7 Ultimate 64Bit RC SQL Server 2005 64bit Developer Edition Virtual: Windows Virtual PC 1G Ram allocated Integration Services installed Windows XP 64bit Up to date service packs and .Net framework through 3.5 SP1 Sharing the Gigabit network adapter of the Host I have a simple .Net console application which loads a dataset of approximately 37K rows. Running the application on the host executes in approximately 4 seconds. Running inside the virtual takes 729 seconds. The size of the application grows to about 65Mb when the dataset is finished loading, no calculated columns or event handlers are attached. [edit] I changed the virtual to use a loopback adapter to communicate with the host and performance is now on par with running on hardware. Any ideas as to why it would going over the network adapter be almost 200x longer? TraceRt shows that the connection is only one hop. Thanks, Shane Holder

  • Threads to make video out of images

    - by masood
    updates: I think/ suspect the imageIO is not thread safe. shared by all threads. the read() call might use resources that are also shared. Thus it will give the performance of a single thread no matter how many threads used. ? if its correct . what is the solution (in practical code) Single request and response model at one time do not utilizes full network/internet bandwidth, thus resulting in low performance. (benchmark is of half speed utilization or even lower) This is to make a video out of an IP cam that gives a new image on each request. http://149.5.43.10:8001/snapshot.jpg It makes a delay of 3 - 8 seconds no matter what I do. Changed thread no. and thread time intervals, debugged the code by System.out.println statements to see if threads work. All seems normal. Any help? Please show some practical code. You may modify mine. This code works (javascript) with much smoother frame rate and max bandwidth usage. but the later code (java) dont. same 3 to 8 seconds gap. <!DOCTYPE html> <html> <head> <script type="text/javascript"> (function(){ var img="/*url*/"; var interval=50; var pointer=0; function showImg(image,idx) { if(idx<=pointer) return; document.body.replaceChild(image,document.getElementsByTagName("img")[0]); pointer=idx; preload(); } function preload() { var cache=null,idx=0;; for(var i=0;i<5;i++) { idx=Date.now()+interval*(i+1); cache=new Image(); cache.onload=(function(ele,idx){return function(){showImg(ele,idx);};})(cache,idx); cache.src=img+"?"+idx; } } window.onload=function(){ document.getElementsByTagName("img")[0].onload=preload; document.getElementsByTagName("img")[0].src="/*initial url*/"; }; })(); </script> </head> <body> <img /> </body> </html> and of java (with problem) : package camba; import java.applet.Applet; import java.awt.Button; import java.awt.Graphics; import java.awt.Image; import java.awt.Label; import java.awt.Panel; import java.awt.TextField; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.net.URL; import java.security.Timestamp; import java.util.Date; import java.util.concurrent.TimeUnit; import java.util.concurrent.atomic.AtomicBoolean; import javax.imageio.ImageIO; public class Camba extends Applet implements ActionListener{ Image img; TextField textField; Label label; Button start,stop; boolean terminate = false; long viewTime; public void init(){ label = new Label("please enter camera URL "); add(label); textField = new TextField(30); add(textField); start = new Button("Start"); add(start); start.addActionListener(this); stop = new Button("Stop"); add(stop); stop.addActionListener(this); } public void actionPerformed(ActionEvent e){ Button source = (Button)e.getSource(); if(source.getLabel() == "Start"){ for (int i = 0; i < 7; i++) { myThread(50*i); } System.out.println("start..."); } if(source.getLabel() == "Stop"){ terminate = true; System.out.println("stop..."); } } public void paint(Graphics g) { update(g); } public void update(Graphics g){ try{ viewTime = System.currentTimeMillis(); g.drawImage(img, 100, 100, this); } catch(Exception e) { e.printStackTrace(); } } public void myThread(final int sleepTime){ new Thread(new Runnable() { public void run() { while(!terminate){ try { TimeUnit.MILLISECONDS.sleep(sleepTime); } catch (InterruptedException ex) { ex.printStackTrace(); } long requestTime= 0; Image tempImage = null; try { URL pic = null; requestTime= System.currentTimeMillis(); pic = new URL(getDocumentBase(), textField.getText()); tempImage = ImageIO.read(pic); } catch(Exception e) { e.printStackTrace(); } if(requestTime >= /*last view time*/viewTime){ img = tempImage; Camba.this.repaint(); } } }}).start(); System.out.println("thread started..."); } }

  • Javascript Split: without losing character

    - by Rohan
    I want to split certain text using JavaSscript. The text looks like: 9:30 pm The user did action A. 10:30 pm Welcome, user John Doe. 11:30 am Messaged user John Doe Now, I want to split the string into events. i.e.: 9:30 pm The user did action A. would be one event. I'm using RegEx for this: var split = journals.split(/\d*\d:/); Thing is, the first two characters are getting lost. The split appears like this: 30 pm The user did action A. How do I split so that the split maintains the first two/three characters (ie 9: or 10:) etc? Thanks!

  • Comparing Page.User.Identity.Name to value in sql Table

    - by Peggy Fusselman
    First, I am SO sorry if the answer is out there. I've looked and looked and feel this is such a simple thing that it should be obvious. I'm wanting to make sure only the person who added an event can modify it. Simple! I already have a datasource that has event_added_by as a data point. It is populating a FormView. SelectCommand="SELECT * FROM [tbl_events] WHERE ([event_ID] = @event_ID)" And I have Page.User.Identity.Name. How do I compare the two? I can't pull the value from the label in the FormView so I need to find another way. if (!IsPostBack) { string uname = Page.User.Identity.Name; string owner = ""// this is where I need to grab the value from dsEvents; if (uname != owner) { //Send them somewhere saying they're not allowed to be here } } TIA for any help!

  • Using Timer only once

    - by zaidwaqi
    Hi, I want to use a timer only once, at 1 second after the initialization of my main form. I thought the following would have a message box saying "Hello World" just once, but actually a new message box says "Hello World" every one second. Why so? I had put t.Stop() in the tick event. Also, do I need to dispose the timer somehow to avoid memory leakage? Timer t = new Timer(); t.Interval = 1000; t.Tick += delegate(System.Object o, System.EventArgs e) { MessageBox.Show("Hello World"); t.Stop(); }; t.Start(); Please help and show if there is a better way of doing this? Thanks.

  • Firefox why window.opener is defined even for a new tab

    - by jonny
    Hi! I am porting quite old corp application from IE to Firefox. Here is my situation. User goes away from computer for a while and his session becomes expired. When user tries to access something in popup, he is being redirected to login page (in popup window). In login page onload event popup window chain is being closed and root page refreshed (in root page tab user is redirected to login page). The guy before me wrote this like this: if window.top.opener is undefined, we're not in popup. That's why I am getting non-stoppable refresh in Firefox. Why in Firefox window.opener is still defined and points to same window, even if this is a new tab, not popup? How should I correctly determine that current window is popup?

  • How to create a GUI inside a function in Matlab?

    - by Paperflyer
    Is there a possibility to write a GUI from inside a function? The Problem is: The callback of all GUI-functions work in the global workspace. But functions have their own workspace and can not access variables in the global workspace. Is there a possibility to make the GUI-functions use the workspace of the function? function myvar = myfunc() myvar = true; h_fig = figure; % create a useless button uicontrol( h_fig, 'style', 'pushbutton', ... 'string', 'clickme', ... 'callback', 'myvar = false' ); % wait for the button to be pressed while myvar pause( 0.2 ); end close( h_fig ); disp( 'this will never be displayed' ); end This event-loop will run indefinitely, since the callback will not modify myvar in the function. Instead it will create a new myvar in the global workspace.

  • Customize Annotation problem....Plz Help.. !!

    - by user128647
    I want to show my custom UIView(.Xib View) to appear when user tabbed on pins (not apple's callOutBubble) and in that UIView there should be a button which fires an IBAction on touched down event. Therefore i have added an AddObserver method to MKAnnotationView. which responds to touch events over pin in MKMapView. But i have also added 3 buttons over that XIB view, which have also assined IBActions. But when i run application, Buttons in Customized Annotation view are not responding to IBAction (Touch Down)? Why this happens ?? What is the solution for that??? I need to have called some method, when those 3 buttons tabbed. Thanks

  • Manipulating individual rows of a datagrid

    - by pfranchise
    Hey, recently I started working on a webpage that has a datagrid. I understand how to add datasources and that sort of thing, or at least I am starting to get it. But my question is about manipulating individual rows or cells. Is that only possible during the databind event handler, that is the only place I have been able to do it so far. I am sure there is a more abstract way of doing the things I want to do, but there are times where I just want to say Datagrid.add(row). I mean, if the datagrid is made up of a certain object type, can I make a new object of that type and just chuck it on the end? I am still new to this stuff, so perhaps what I want to do would defeat the purpose of this added abstraction, but figured I would ask around. Thanks for any advice, tips, or tricks people feel like sharing. Edit: for clarification I am using c#, entity framework, asp.net, and an SQL database.

  • How do I do a join in ActiveRecord after records have been returned?

    - by Russ Bradberry
    I am using ActiveRecord in Rails 3 to pull data from two different tables in two different databases. These databases can not join on each other, but I have the need to do a simple join after-the-fact. I would like to preserve the relation so that I can chain it down the line. here is a simplified version of what I am doing browsers = Browser.all # <-- this is fairly small and can reside in memory events = Event.where(:row_date=>Date.today).select(:name, :browser_id) So as you can see, I want to join browsers in on the events relation, where browser_id should equal browsers.name. events is a relation and I can still add clauses to it down the line, so I dont want to run the query on the db just yet. How would I accomplish this?

  • MasterPage Page_Load hits before Grid_ItemCommand

    - by Raheel Khan
    I am using the session object to store success/error messages based on user actions. On each postback, the message is set on ItemCommend and retrieved on the Page_Load of the master page. Once retrieved, the message is deleted from the session. The problem is that the master page's Page_Load gets called before the ItemCommand gets called so the message does not show up until the next refresh or postback. How is this situation normally handled? Is there some other event we can code against?

  • Form Inheritance in Visual Studios designer implementations

    - by CooPzZ
    I'm in the process of Moving a project from Visual Studio 2003 to 2005 and have just seen the The event Click is read-only and cannot be changed when using inherited forms regardless of the Modifier on the Base Forms Controls will make all the Controls from the Base Readonly in the designer (Though in 2003 it didn't work this way). I found this post metioning that this functionality has been temporarily" disabled http://social.msdn.microsoft.com/Forums/en-US/winformsdesigner/thread/c25cec28-67a5-4e30-bb2d-9f8dbd41eb3a Can anyone confirm whether this feature is used anymore? or how to program around it to be able to use the Base Control Events and still have a designer? This is one way I've found but quite painfull when it used to do the plumbing for you. even just hiding one of the controls you have manually do now. Public Class BFormChild Friend Overrides Sub cmdApply_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdApply_Click(sender, e) End Sub Friend Overrides Sub cmdCancel_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdCancel_Click(sender, e) End Sub Friend Overrides Sub cmdOk_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdOk_Click(sender, e) End Sub End Class

  • C# Custom Control Properties load before Load and arrays are empties

    - by Wildhorn
    Hello, I made a custom control with custom properties. When I modify these properties in the "Form.cs [Design]", I need stuff to happens (it fill some arrays and modify the look of the control), so I call a function within the "set" of the property. All of this works good. My problem is that when I run the program with my custom control, it seems that properties "set" is called, which will call the function, but then, my arrays seems now to have lost all their values and the function use these arrays, but now because they are all empty, it crashes due to NullException blahblahblah. It also seems that properties "set" is called before the control Load (which I guess is called only when it is added to my Form, and not when the Form load). So question is, why does my arrays become empty once I try to run the Form and is there an event that is called before that when the Form load? Thanks

  • Creating a file upload template in Doctrine ORM

So hopefully I can do something like: File: actAs: BalFile: columns: id: primary: true type: integer(4) unsigned: true code: type: string(255) unique: true notblank: true path: type: string(255) notblank: true size: type: integer(4) type: type: enum values: [file,document,image,video,audio,web,application,archive] default: unknown notnull: true mimetype: type: string(20) notnull: true width: type: integer(2) unsigned: true height: type: integer(2) unsigned: true I'm hoping for a validator so that say if I do $File->setFile($_FILE['uploaded_file']); It will provide a validation error, except in all the doctrine documentation it has little on custom validators, especially in the contect of "virtual" fields. So in summary, my question is: How earth can I go about making a template/extension to porting this functionality? I have tried before with templates but always gave up after a day :/ If you could take the time to port the above I would greatly appreciate it.
