  • How to Make Flash Builder Package Explorer emulate Flex Builder’s Navigator window?

    - by eco_bach
    Hi Does anyone know if there is a way to make the new Package Explorer window in Flash Builder emulate Flex Builders 'Flex navigator' window? Bottom line is I don't always need to peer into SWC's, and I don't like having a 'default package' automatically created for me. Not sure why the interface wasn't made simpler, allowing access to more power and complexity only if necessary. I want to focus on the code, not on how to navigate and use the bells and whistles in the coding environment.

  • Can you exclude code automatically when using the publish feature in Visual Studio

    - by LarryDev
    Is their a way to exclude a block of code when you use the publish feature in visual studio. In other words say I had a log in button that did something like: // Start Exclude when publishing if (txtUserName.Text == "" && txtPassword.Password == "") { lp = new System.ServiceModel.DomainServices.Client.ApplicationServices.LoginParameters("UserName", "Password"); } else // Stop Exclude when publishing { lp = new System.ServiceModel.DomainServices.Client.ApplicationServices.LoginParameters(txtUserName.Text, txtPassword.Password); } This way when I am debugging I can just leave the username and password field blank and just click login and the application will log me on. But when the application is published the compiler woudl ignore that code and not compile it in to the application.

  • How to Access a Button present inside a Custom Control, from the implementing page?

    - by Subhen
    Hi, I have my generic.xaml containing the following code: <ControlTemplate TargetType="local:customVideoControl"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="600"/> <RowDefinition Height="200"/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="200"/> <ColumnDefinition Width="200"/> <ColumnDefinition Width="200"/> </Grid.ColumnDefinitions> <MediaElement x:Name="customMediaPlayer" Source="{TemplateBinding CustomMediaSource}" HorizontalAlignment="Center" VerticalAlignment="Center" Height="{TemplateBinding Height}" Width="{TemplateBinding Width}" Grid.Row="0" Grid.ColumnSpan="3" /> <ToggleButton x:Name="playPauseBtn" Height="50" Width="50" Content="Pause" Grid.Row="1" Grid.Column="0"/> <Button x:Name="prevBtn" Height="50" Width="50" Content="Prev" Grid.Row="1" Grid.Column="1"/> <Button x:Name="nextBtn" Height="50" Width="50" Content="Next" Grid.Row="1" Grid.Column="2"/> </Grid> </ControlTemplate> Now on applyTemplate , I am accessing the controls like below: public override void OnApplyTemplate() { base.OnApplyTemplate(); ToggleButton playPauseBtn = GetTemplateChild("playPauseBtn") as ToggleButton; Button prevBtn= GetTemplateChild("prevBtn") as Button; Button nextBtn = GetTemplateChild("nextBtn") as Button; MediaElement customMediaPlayer = GetTemplateChild("customMediaPlayer") as MediaElement; playPauseBtn.Checked += (obj, Args) => { customMediaPlayer.Pause(); playPauseBtn.Content = "Play"; }; playPauseBtn.Unchecked += (obj, Args) => { customMediaPlayer.Play(); playPauseBtn.Content = "Pause"; }; nextBtn.Click += (obj, Args) => { customMediaPlayer.Source=new Uri(CustomMediaSource.ToString(),UriKind.RelativeOrAbsolute); }; prevBtn.Click += (obj, Args) => { customMediaPlayer.Source = new Uri(CustomMediaSource.ToString(), UriKind.RelativeOrAbsolute); }; } Now I want acccess the nextBtn, in the page where I am implementing like CustomVideoControl myVControl=new CustomVideoControl(); This will create the instance of the control, but I want to do something on the click of next and previous button, thta is present inside the CustomVideoControl in generic.xaml. Any help will be greatly appreciated. Thanks, Subhen

  • CAML queries: how to filter folders from result set?

    - by drax
    Hi all, I'm using caml query to select all documents which were modified or added by user. Query runs recursively on all subsites of specified site collection. Now problem is I can't get rid of folders which are also part of result set. For now I'm filtering them from result datatable. But I'm wondering: Is it possible to filter out folders from result set just by using caml?

  • How to add a has_many association on all models

    - by joshsz
    Right now I have an initializer that does this: ActiveRecord::Base.send :has_many, :notes, :as => :notable ActiveRecord::Base.send :accepts_nested_attributes_for, :notes It builds the association just fine, except when I load a view that uses it, the second load gives me: can't dup NilClass from: /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2184:in `dup' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2184:in `scoped_methods' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2188:in `current_scoped_methods' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2171:in `scoped?' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2439:in `send' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2439:in `initialize' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/reflection.rb:162:in `new' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/reflection.rb:162:in `build_association' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/associations/association_collection.rb:423:in `build_record' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/associations/association_collection.rb:102:in `build' (my app)/controllers/manifests_controller.rb:21:in `show' Any ideas? Am I doing this the wrong way? Interestingly if I move the association onto just the model I'm working with at the moment, I don't get this error. I figure I must be building the global association incorrectly.

  • JS Object this.method() breaks via jQuery

    - by Peter Boughton
    I'm sure there's a simple answer to this, but it's Friday afternoon and I'm tired. :( Not sure how to explain it, so I'll just go ahead and post example code... Here is a simple object: var Bob = { Stuff : '' , init : function() { this.Stuff = arguments[0] } , doSomething : function() { console.log( this.Stuff ); } } And here it is being used: $j = jQuery.noConflict(); $j(document).ready( init ); function init() { Bob.init('hello'); Bob.doSomething(); $j('#MyButton').click( Bob.doSomething ); } Everything works, except for the last line. When jQuery calls the doSomething method it is overriding 'this' and stopping it from working. Trying to use just Stuff doesn't work either. So how do I refer to an object's own properties in a way that allows jQuery to call it, and also allows the object to work with the calling jQuery object? i.e. I would like to be able to do things like this: doSomething : function() { console.log( <CurrentObject>.Stuff + $j(<CallerElement>).attr('id') ); } (Where <CurrentObject> and <CallerElement> are replaced with appropriate names.)

  • handle an arrray posted with $.ajax (jquery) to a webservice

    - by burktelefon
    I'm trying to post data to a webservice (asp.net 3.5), like below (two variants, one commented): var array = [3, 2, 5, 1, 7]; var jsonString = JSON.stringify(array); //var jsonString = '{ "firstName": "John", "lastName": "Smith", "age": 25, "address": { "streetAddress": "21 2nd Street", "city": "New York", "state": "NY", "postalCode": "10021" }, "phoneNumber": [ { "type": "home", "number": "212 555-1234" }, { "type": "fax", "number": "646 555-4567" } ] }' $.ajax({ type: "POST", url: "WebService2.asmx/AddRoute", data: jsonString, contentType: "application/json; charset=utf-8", dataType: "json", processData: "false", error: function(msg) { alert('error' + msg.toString); } }); So I need a matching webmethod to recieve it. Something like this: [WebMethod] public string AddRoute(/* xxx */) { //handle data } Could someone please elaborate on how I can fetch the data, where I've typed "xxx"? I would have thought "int[] array" would do the trick, but it's not working. Any help would be greatly appreciated :)

  • Should I denormalize a has_many has_many?

    - by Cameron
    I have this: class User < ActiveRecord::Base has_many :serials has_many :sites, :through => :series end class Serial < ActiveRecord::Base belongs_to :user belongs_to :site has_many :episodes end class Site < ActiveRecord::Base has_many :serials has_many :users, :through => :serials end class Episode < ActiveRecord::Base belongs_to :serial end I would like to do some operations on User.serials.episodes but I know this would mean all sorts of clever tricks. I could in theory just put all the episode data into serial (denormalize) and then group_by Site when needed. If I have a lot of episodes that I need to query on would this be a bad idea? thanks

  • Highlight Read-Along Text (in a storybook type app for iPhone)

    - by outtoplayinc
    I love this feature (well, my son loves it), and I would like to implement it in a kid's book app I am doing for iPhone, but I'm clueless where to begin. I'm using Cocos2d for all the animated sprite/transition stuff, but I'm not sure how to approach highlighting text as it is narrated. Example: "Jack and Jill, drank their fill, and were too drunk to go for water." As the text is narrated (.mp3 plays on each page), the text would be highlighted. I considered investigating Core animation, but I"m more familiar with Cocs2d at this point (tenuously at best). If someone has a clue, I'd really appreciate it. Brendang

  • What is the opposite of Jquery .not - OR - How to I target href links that contain the following....

    - by stolkramaker
    Right. So here we go. I am currently using the following code to target all links and apply an iframe toolbar $("a[href^='http:']").not("[href*='www.domiain.com']").not("[href*='www.twitter.com']").each(function(){ var tempurl = 'http://www.domain.com/shiftbar/shiftbar.html?iframe='; var $this = $(this); var currenturl = this.getAttribute("href"); var href = tempurl + currenturl; $this.attr('href', href ); }); I need to do the same, but now for links that ONLY contain twitter $("a[href^='http:']").contains("[href*='www.twitter.com']").each(function(){ $this.attr("target", "_blank"); }); it doesn't work. I've tried .has .contains But I suppose I am not familiar with jquery enough at this point.

  • Using the XElement.Elements method, can I find elements with wildcard namespace but the same name?

    - by gav
    Hi All, Trying to do a simple parse of an XML document. What's the easiest way to pull out the two PropertyGroups below? <Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <PropertyGroup xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> 1 </PropertyGroup> <PropertyGroup xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> 2 </PropertyGroup> </Project> I have been trying to use XElement.Elements(XName) but to do so I need to prefix PropertyGroup with the xmlns. The issue is that I don't care about the name space and if it changes in future I would still like all PropertyGroups to be retrieved. var xml = XElement.Load(fileNameWithPath); var nameSpace = xml.GetDefaultNamespace(); var propertyGroups= xml.Elements(nameSpace + "PropertyGroup"); Can you improve on this code such that I don't need to prepend with nameSpace? I know I can essentially just reimplement the Elements method but I was hoping there was some way to pass a wildcard namespace? Thanks, Gavin

  • How to round a number to n decimal places in Java

    - by Alex Spurling
    What I'd like is a method to convert a double to a string which rounds using the half-up method. I.e. if the decimal to be rounded is a 5, it always rounds up the previous number. This is the standard method of rounding most people expect in most situations. I also would like only significant digits to be displayed. That is there should not be any trailing zeroes. I know one method of doing this is to use the String.format method: String.format("%.5g%n", 0.912385); returns: 0.91239 which is great, however it always displays numbers with 5 decimal places even if they are not significant: String.format("%.5g%n", 0.912300); returns: 0.91230 Another method is to use the DecimalFormatter: DecimalFormat df = new DecimalFormat("#.#####"); df.format(0.912385); returns: 0.91238 However as you can see this uses half-even rounding. That is it will round down if the previous digit is even. What I'd like is this: 0.912385 -> 0.91239 0.912300 -> 0.9123 What is the best way to achieve this in Java?

  • Flexible classroom environments (OS, Office)

    - by HannesFostie
    I work in the IT department of a training center, we still offer XP and Office 2003 trainings but also offer Vista and Win7 and Office 2007. Currently, we use VMs on VMware Server but this is obviously not a superb choice. We're thinking of implementing something like VDI (brainstorm phase, we hardly have any details) but I decided to check here if people would have some clever alternatives. Requirements: * Flexible when it comes to deployment * Centralized management would be a big plus * Allow for different software, whether they be compatible or not (all of office except for outlook can be installed simultaneously. for outlook you need to choose between 2003 or 2007) * Allow for different OS We have a big enough budget to implement a proper SAN environment to accomodate the virtualization of the solution, whatever kind it may be. A support contract will probably be necessary as well, because we need to be able to offer quick solutions to problems and with only 2 sysadmins that is simply impossible to guarantee.
