  • Automating Firefox configuration settings

    - by Richard100
    Hi All, During web development work, I need to be able to quickly switch various config settings in Firefox. In particular I need to be able to: 1) Switch off cookies 2) Switch off javascript 3) Switch my user agent (I have the user-agent switcher add-on installed) and then back again. Instead of doing this manually, it would be great if i could add a "macro" button to my toolbar that I could simply click to toggle the three settings above. Anyone know if this is possible? Btw - Firefox Profiles doesn't really cut it. You can't dynamically switch profiles within a specific Firefox instance, which I need to be able to do. Btw2 - I got excited when i saw Greasemonkey, Chicken Foot, but it looks like these can only automate browsing/DOM tasks, and not with firefox configuration settings. Thanks Richard.

  • How can I make a read-only ObservableCollection property?

    - by thrag
    I'd like to expose a property on a view model that contains a list of objects (from database). I need this collection to be read-only. That is, I want to prevent Add/Remove, etc. But allow the foreach and indexers to work. My intent is to declare a private field holding the editable collection and reference it with a read-only Public Property. As follows public ObservableCollection<foo> CollectionOfFoo { get { return _CollectionOfFoo; } } However, that syntax just prevents changing the reference to the collection. It doesn't prevent add/remove, etc. What is the right way to accomplish this?

  • Pomodoro technique & other ways to increase personal productivity? Any ideas?

    - by Jayson
    I recently came across Pomodoro Technique as a way to increase productivity, get in the zone, and in general feel a sense of accomplishment at setting some short programming goals and achieving them. So far I have enjoyed it and the sense of accomplishment I get after seeing a bunch of short goals add up at the end of the day to a lot of work done on a programming project. I'm looking for other ideas similar or not to the pomodoro technique to add a little variety to achieving goals, personal productivity, get in the programming zone, etc. Any ideas or techniques that are expressed formally such as in the pomodoro paper, that are not trite fluffy maxims?

  • Reduce the file size of Excel

    - by Ram
    Hi, I'm working in an excel application and providing a menu to the user to add a new worksheet in that excel application (Excel Workbook). The worksheet will be added once the user clicks the "OK" button and I'm using a template to add this worksheet (The template has lot of formatting and formulas in it) Lets say the file size is 10 MB after adding a worksheet if the workbook is saved. Then I close the Excel application and reopen it and save the file then the file size is getting reduced to 8 MB. Can anybody let me know what could be the reason for the same? Thanks, Ram

  • [dynamic] Different behaviours between .NET 4.0 beta 2 and last release of .NET 4.0 !

    - by yogi4ever
    Hi. I've identified a difference of DLR between .NET 4.0 Beta 2 and the last release of .NET 4.0. In .NET 4.0 Beta 2, this code perfectly works at runtime : var dateTimeList = new List(); dynamic myDynamicObject = dateTimeList; object value = DateTime.Now; myDynamicObject.Add(value); Now, with last release of .NET 4.0, I have an exception at run time (to solve myDynamicObject.Add(value);) :-( In my real code, 'myDynamicObject' is a dynamic (but I know that it is always an ObservableCollection where T can be anything). 'value' is an instance which was got by some reflexions. As 'value' can have any type, the type of 'value' is Object. Do you see how can I solve this new limitation of .NET 4.0 ? Thanks

  • SQL Design Question regarding schema and if Name value pair is the best solution

    - by Aur
    I am having a small problem trying to decide on database schema for a current project. I am by no means a DBA. The application parses through a file based on user input and enters that data in the database. The number of fields that can be parsed is between 1 and 42 at the current moment. The current design of the database is entirely flat with there being 42 columns; some have repeated columns such as address1, address2, address3, etc... This says that I should normalize the data. However, data integrity is not needed at this moment and the way the data is shaped I'm looking at several joins. Not a bad thing but the data is still in a 1 to 1 relationship and I still see a lot of empty fields per row. So my concerns are that this does not allow the database or the application to be very extendable. If they want to add more fields to be parsed (which they do) than I'd need to create another table and add another foreign key to the linking table. The third option is I have a table where the fields are defined and a table for each record. So what I was thinking is to make a table that stores the value and then links to those two tables. The problem is I can picture the size of that table growing large depending on the input size. If someone gives me a file with 300,000 records than 300,000 x 40 = 12 million so I have some reservations. However I think if I get to that point than I should be happy it is being used. This option also allows for more custom displaying of information albeit a bit more work but little rework even if you add more fields. So the problem boils down to: 1. Current design is a flat file which makes extending it hard and it is not normalized. 2. Normalize the tables although no real benefits for the moment but requirements change. 3. Normalize it down into the name value pair and hope size doesn't hurt. There are a large number of inserts, updates, and selects against that table. So performance is a worry but I believe the saying is design now, performance testing later? I'm probably just missing something practical so any comments would be appreciated even if it’s a quick sanity check. Thank you for your time.

  • FLEX: sequence of puppets... 3 requirements

    - by Patrick
    hi, I'm implementing this sequence of puppets in flex: http://dl.dropbox.com/u/72686/itemsSequence.png I want to show the caption when the mouse rolls over the puppet I want the user being able to click on the buttons of the caption (so the caption doesn't have to disappear when I move the mouse out from the user over the caption). I don't want the puppet component to become bigger when the caption is added (it becomes visible), because the puppets have to stay nearby each other, I cannot resize the objects. So.. I need some guidelines to do it. More precisely: 1) Should I add the components in MXML or pure actionscript ? 2) If I use MXML, should I add also the caption to the flex model, and make it invisible and then change the value with actionscript ? What's the common way to implement it ? thanks

  • where to store information like gender and year of birth?

    - by fayer
    i have users and i need them to specify a gender (male, female) and year of birth (1930, 1931...1999, 2000). i wonder where i should store these values: in the database? in php file? if i store them in the database i have to manually create all entries first. but a good thing is that the user table will have constraints so the gender field will always be male or female, it cannot be something else. if i store them in the php file (eg. as html) then i can easily add/remove values. but a con is that i dont have the constraints in database, so another value could be stored as gender by mistake, even though i could add validation in php backend so even if someone hacked the html it is not stored unless it's either male or female. what is best practice to do this? thanks

  • Swing invokeLater never shows up, invokeAndWait throws error. What can I do?

    - by Geo
    I have this code: try { SwingUtilities.invokeAndWait(new Runnable() { public void run() { try { dialog.handleDownload(); } catch (IOException io) { io.printStackTrace(); } } }); } catch(Exception io) { io.printStackTrace(); } in the handleDownload I'm reading an inputstream, calculating a progress bar's value, and setting it to that. So, when I click a button, a new JFrame opens up and does all the stuff I wrote above. If I have the dialog.handleDownload by itself ( in no SwingUtilities method ), it freezes until the operation is finished. If I add it in a invokeLater it's closed very fast ( I can't see anything, and the operation is not finished ). If I add it in a invokeAndWait I get the invokeAndWait cannot be called from the event dispatcher thread error. What should I do?

  • JPanel's child components paint/layout problem

    - by Tom Brito
    I'm having a problem that when my frame is shown (after a login dialog) the buttons are not on correct position, then in some miliseconds they go to the right position (the center of the panel with border layout). When I make a SSCCE, it works correct, but when I run my whole code I have this fast-miliseconds delay to the buttons to go to the correct place. Unfortunately, I can't post the whole code, but the method that shows the frame is: public void login(JComponent userView) { centerPanel.removeAll(); centerPanel.add(userView); centerPanel.revalidate(); centerPanel.repaint(); frame.setVisible(true); } What would cause this delay to the panel layout? (I'm running everything in the EDT) -- update In my machine, this SSCCE shows the layout problem in 2 of 10 times I run it: import java.awt.BorderLayout; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.SwingUtilities; public class TEST { public static void main(String[] args) throws Exception { SwingUtilities.invokeAndWait(new Runnable() { @Override public void run() { System.out.println("Debug test..."); JPanel btnPnl = new JPanel(); btnPnl.add(new JButton("TEST")); JFrame f = new JFrame("TEST"); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.getContentPane().setLayout(new BorderLayout()); f.getContentPane().add(btnPnl); f.pack(); f.setSize(800, 600); f.setVisible(true); System.out.println("End debug test!"); } }); } } The button first appers in the up-left, and then it goes to the center. Please, note that I'm understand, not just correct. Is it a java bug? --update OK, so the SSCCE don't show the problem with you that tried till now. Maybe it's my computer performance problem. But this don't answer the question, I still think Java Swing is creating new threads for make the layout behind the scenes.

  • Unable to modify a table

  • Instantiating custom PropertySourcesPlaceholderConfigurer from spring context

    - by mmona
    I want to define a custom PropertySourcesPlaceholderConfigurer in spring context xml. I want to use there multiple PropertySources, so that I can load part of the configuration from several property files and provide other part dynamically by my custom PropertySource implementation. The advantage is that it should be then easy to adjust the order of loading these property sources just by making modifications to the xml spring configuration. And here I run into a problem: how to define an arbitrary list of PropertySources and inject it into PropertySourcesPlaceholderConfigurer, so that it uses the sources defined by me? Seems to be a basic thing that should be provided by spring, but since yesterday I cannot find a way to do it. Using namespace would enable me to load several property files, but I also need to define the id of the PropertySourcesPlaceholderConfigurer (as other projects refer to it), and also I want to use my custom implementation. That is why I am defining the bean explicitly and not using the namespace. The most intuitive way would be to inject a list of PropertySources into PropertySourcesPlaceholderConfigurer like this: <bean id="applicationPropertyPlaceholderConfigurer" class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer"> <property name="ignoreUnresolvablePlaceholders" value="true" /> <property name="ignoreResourceNotFound" value="true" /> <property name="order" value="0"/> <property name="propertySources"> <list> <!-- my PropertySource objects --> </list> </property> </bean> but unfortunately propertySources is of type PropertySources and does not accept a list. The PropertySources interface has one and only implementor which is MutablePropertySources, which indeed stores list of PropertySource objects, but has no constructor nor setter through which I can inject this list. It only has add*(PropertySource) methods. The only workaround I see now is to implement my own PropertySources class, extending MutablePropertySources, which would accept list of PropertySource objects on creation and manually add it via using add*(PropertySource) method. But why so much workaround would be needed to provide something that I thought was supposed to be the main reason of introducing the PropertySources (having flexible configuration manageable from spring configuration level). Please clarify what am I getting wrong :)

  • Application Servers(java) : Should adding RAM to server depend on each domain's -Xmx value?

    - by ring bearer
    We have Glassfish application server running in Linux servers. Each Glassfish installation hosts 3 domains. Each domain has a JVM configuration such as -Xms 1GB and -XmX 2GB. That means if all these three domains are running at max memory, server should be able to allocate total 6GB to the JVMs With that math,each of our server has 8GB RAM (2 GB Buffer) First of all - is this a good approach? I did not think so, because when we analyzed memory utilization on this server over past few months, it was only up to 1GB; Now there are requests to add an additional domain to these servers - does that mean to add additional 2 GB RAM just to be safe or based on trend, continue with whatever memory the server has?

  • jQuery - How do I make the menu fadeout when the user clicks anywhere else in the document besides the menu itself?

    - by GirlGoneMad
    Hi, I have a link that functions similar to a drop down menu in that it fades in a list of links below it when clicked. Currently, the list fades back out when the link is clicked again, but I'd like for it to also fade out if the user clicks elsewhere on the page. I'm not sure how to add the $(document).click(function()... that handles this, or if this is even the right approach. Here is my code: $('#show_button').click( function(){ if(!$('#list').is(':visible')){ var pos = $('#show_button').offset(); $('#list').css({'left':pos.left - 11, 'top': pos.top+14}).fadeIn(); } else{ $('#list').fadeOut(); } }); I am trying to add something like this to make the list fade out when the user clicks anywhere else in the page: if($('#list').is(':visible')){ $(document).click(function() { $('#list').fadeOut(); }); } Thanks in advance - I would appreciate any help on this one :)

  • How can I traverse a reverse generic relation in a Django template?

    - by user569139
    I have the following class that I am using to bookmark items: class BookmarkedItem(models.Model): is_bookmarked = models.BooleanField(default=False) user = models.ForeignKey(User) content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey() And I am defining a reverse generic relationship as follows: class Link(models.Model): url = models.URLField() bookmarks = generic.GenericRelation(BookmarkedItem) In one of my views I generate a queryset of all links and add this to a context: links = Link.objects.all() context = { 'links': links } return render_to_response('links.html', context) The problem I am having is how to traverse the generic relationship in my template. For each link I want to be able to check the is_bookmarked attribute and change the add/remove bookmark button according to whether the user already has it bookmarked or not. Is this possible to do in the template? Or do I have to do some additional filtering in the view and pass another queryset?

  • iOS - Losing in-app subscription?

    - by user3280451
    I've just built an iOS app that uses a non-reoccuring subscription model. You hit "buy" and then when the client device receives the receipt from the Apple server it whizzes it off to my server to validate it and add the subscription to my user database. If the connection fails before my server has responded then the request is cached, ready to be resent the next time the client comes online. My problem is, what happens if the connection fails between when the user hits the buy button and the receipt is received by the client from Apple? Theres no way for it to know that the purchase has been made? Presumably I should add a "restore purchases" button that sends all of the users receipts to my server which checks if they've already been validated and their respective subscriptions added to the database? Is there a less intrusive way of doing this?

  • Jquery persistent css selector equivalent to '.live()'

    - by Dan
    So today I just came across the 'live()' function that binds any future and past elements to the whatever event you choose, such as 'onclick'. Right now I'm having to set up buttons like the following each time I load a new button via ajax ... $('a.btn.plus').button({icons:{primary:'ui-icon-plusthick'}}); $('a.btn.pencil').button({icons:{primary:'ui-icon ui-icon-pencil'}}); $('a.btn.bigx').button({icons:{primary:'ui-icon ui-icon-closethick'}}); So, instead of calling these lines each time I use ajax to add a new button, is there a similar way to tell JQuery to setup my buttons ANYTIME I add new ones? Thanks for any help!

  • How to change "area" of a control in DesignMode?

    - by Tronex
    When I drag and drop a TextBox from the toolbox onto a WinForm, I can drag it around on the form as I like. Now I create a new class and inherit it from TextBox. I add a new property called CaptionLabel. When set to a value, I dynamically create a Label control, set its value and finally add the label to the TextBox' parent controlcollection. The result is a "LabeledTextBox". However, when selecting the TextBox, I still only get the TextBox selected... the selection rectangle does not include the Label, created dynamically. How do I extend the rectangle so that it also contains the Label and make the label "know" that it belongs to the TextBox? Or is there a better way to create labeled controls?

  • Animate a e.Graphics.DrawLine with arrowhead

    - by Fer
    I need to "animate" an arrow. It can go in any direction (up, down, left, right and diagonals) and the arrowhead will be at the end. It needs to appear as if it is growing from orgin to the end. To make matters more complicated it has to be in a user control so it is possible to add to the controls collection in the forms and remove it to delete it from the screen, and its background is really transparent (no color.transparent) so i can't paint the background to "clear" the previous line. I have it static already (drawn from origin to end) but i can't animate it. I tried to add a timer in the user control but I fail to get a correct algorithm to calculate the intermediate ends of the line while it is growing. Any help would be appreciated. Thanks
