  • Why should I use a puppet parametrized class?

    - by robbyt
    Generally when working with complex puppet modules, I will set variables at the node level or inside a class. e.g., node 'foo.com' { $file_owner = "larry" include bar } class bar { $file_name = "larry.txt" include do_stuff } class do_stuff { file { $file_name: ensure => file, owner => $file_owner, } } How/when/why does parametrized classes help when this situation? How are you using parametrized classes to structure your puppet modules?

  • Firefox, reload without cache check

    - by pmoleri
    It looks like a popular question but it's just the opposite. When I visit a site in Firefox 15 I have two different behaviours when: Pressing enter in the address bar Pressing F5 or the refresh button If I look in the network console I can see that F5 does a lot more requests, most of them about cached resources and with a 304-Not Modified answer. Is there's any shortcut to make a quick refresh? Just like pressing enter on the address bar.

  • WPF ListView ScrollViewer Double-Click Event

    - by Sentax
    Doing the below will reproduce my problem: New WPF Project Add ListView Name the listview: x:Name="lvList" Add enough ListViewItems to the ListView to fill the list completely so a vertical scroll-bar appears during run-time. Put this code in the lvList.MouseDoubleClick event Debug.Print("Double-Click happened") Run the application Double-click on the LargeChange area of the scroll-bar (Not the scroll "bar" itself) Notice the Immediate window printing the double-click happened message for the ListView How do I change this behavior so MouseDoubleClick only happens when the mouse is "over" the ListViewItems and not when continually clicking the ScrollViewer to scroll down/up in the list?

  • Silverlight RelativeSource of TemplatedParent Binding within a DataTemplate, Is it possible?

    - by Matt.M
    I'm trying to make a bar graph Usercontrol. I'm creating each bar using a DataTemplate. The problem is in order to compute the height of each bar, I first need to know the height of its container (the TemplatedParent). Unfortunately what I have: Height="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Height, Converter={StaticResource HeightConverter}, Mode=OneWay}" Does not work. Each time a value of NaN is returned to my Converter. Does RelativeSource={RelativeSource TemplatedParent} not work in this context? What else can I do to allow my DataTemplate to "talk" to the element it is being applied to? Incase it helps here is the barebones DataTemplate: <DataTemplate x:Key="BarGraphTemplate"> <Grid Width="30"> <Rectangle HorizontalAlignment="Center" Stroke="Black" Width="20" Height="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Height, Converter={StaticResource HeightConverter}, Mode=OneWay}" VerticalAlignment="Bottom" /> </Grid> </DataTemplate>

  • multiple key ranges as parameters to a couchdb view

    - by kolosy
    is there a way to send multiple startKey/endKey pairs to a view, akin to the keys: [] array that can be posted for keys? the underlying problem - let's say my documents have "categories" and timestamps. if i want all documents in the "foo" category that have a timestamp that's within the last two hours, it's simple: function (doc) { emit([doc.category, doc.timestamp], null); } and then query as GET server:5894/.../myview?startKey=[foo, |now - 2 hours|]&endkey=[foo, |now|] the problem comes when i want something in categories foo or bar, within the last two hours. if i didn't care about time, i could just pull directly by key through the keys collection. unfortunately, i have no such option with ranges. what i ended up doing in the meantime is rounding the timestamp to two-hour blocks, and then multiplexing the query out: POST server:5894/.../myview keys=[[foo, 0 hours], [foo, 2 hours], [bar, 0 hours], [bar, 2 hours]] it works, but will get messy if i want to go back a large amount of time (in relationship to the blocksize)

  • UINavigationBar height

    - by kpower
    In my app I work with an UINavigationController. I've added it to the window (MainWindow.xib, with IB) and simulated on my main view (in IB: Simulated User Elements / Top Bar / Navigation Bar). Navigation bar is displayed, but its height isn't standard. At least in IB it is bigger than in launched app. What's wrong? And how can I restore height to the initial state (as in IB)? P.S.: I know that I can set it directly from code. But this way looks like a "crutch".

  • Nullable One To One Relationships with Integer Keys in LINQ-to-SQL

    - by Craig Walker
    I have two objects (Foo and Bar) that have a one-to-zero-or-one relationship between them. So, Foo has a nullable foreign key reference to Bar.ID and a (nullbusted) unique index to enforce the "1" side. Bar.ID is an int, and so Foo.BarID is a nullable int. The problem occurs in the LINQ-to-SQL DBML mapping of .NET types to SQL datatypes. Since int is not a nullable type in .NET, it gets wrapped in a Nullable<int>. However, this is not the same type as int, and so Visual Studio gives me this error message when I try to create the OneToOne Association between them: Cannot create an association "Bar_Foo". Properties do not have matching types: "ID", "BarID". Is there a way around this?

  • Show CMFCRibbonStatusBar

    - by praetorian20
    Hi, I'm creating a simple SDI app using the new VS2008 service pack. I added ribbon support but all I want on the ribbon are the Open & Close buttons. I commented out all the code that creates the other default buttons and categories but doing this also gets rid of the status bar (CMFCRibbonStatusBar). I can't find what member function is called when I click the checkbox that displays the statusbar in the default generated code. I've tried the following but it doesn't work: m_wndStatusBar.ShowWindow( SW_SHOWNORMAL ); How do I have the status bar showing without having to have the 'Home' category and 'View' panel (with the 'Show status bar' checkbox) being generated? Thanks, Ashish.

  • intercept RelativeSource FindAncestor

    - by Pradeep
    I have a WPF application which runs as a excel plugin, it has its visual tree like so Excel ElementHost WPF UserControl WPF ribbon bar control Now any controls sitting on the WPF ribbon bar control are not enabled when the plugin is loaded within excel. See error below System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Window', AncestorLevel='1''. BindingExpression:Path=IsActive; DataItem=null; target element is 'Ribbon' (Name=''); target property is 'NoTarget' (type 'Object') If I nest the ribbon bar control in a standalone Window(outside excel) it works fine. Is there a way to intercept the FindAncestor call for a Window and wire it to something else.? Note that I cannot change the above binding as it isn't my control.

  • Clip UITableView Cell's Separator

    - by Drewsmits
    I've been trying to build a view that looks similar to the "stocks" application (surprise). What I would like is to have the scroller bar outside of my rounded table view, shown in the image link below, but clip the cell separators. You can see how they overlap the scroller bar, which is annoying. I can't figure out how Apple put the scroller bar in a spot that looks like it is outside their table. Any ideas? (sorry, can't imbed images yet because I'm a new user). Scroller Problem Image

  • Python dictionary: add or increment entry

    - by cursa
    Hi everyone, I'm currently re-engaging with Python after a long absence and loving it. However, I find myself coming across a pattern over and over. I keep thinking that there must be a better way to express what I want and that I'm probably doing it the wrong way. The code that I'm writing is in the following form: # foo is a dictionary if foo.has_key(bar): foo[bar] += 1 else: foo[bar] = 1 I'm writing this a lot in my programs. My first reaction is to push it out to a helper function, but so often the python libraries supply things like this already. Is there some simple little syntax trick that I'm missing? Or is this the way that it should be done?

  • using objc_msgSend to call a Objective C function with named arguments

    - by Markus Pilman
    Hi all, I want to add scripting support for an Objective-C project using the objc runtime. Now I face the problem, that I don't have a clue, how I should call an Objective-C method which takes several named arguments. So for example the following objective-c call [object foo:bar]; could be called from C with: objc_msgSend(object, sel_getUid("foo:"), bar); But how would I do something similar for the method call: [object foo:var bar:var2 err:errVar]; ??

  • Calling a GWT service in a different context than the GWT Module Base?

    - by Epaga
    I have a GWT module with the X-GWT-Module-Base http://host:8080/foo/ and would like to call a (GWT) service which is located at http://host:8080/bar/. The reason is for example that I want to be able to share a GWT service between two different GWT client projects. All I've gotten to work so far is if the service is located within the module context, i.e. http://host:8080/foo/bar works fine, using @RemoteServiceRelativePath("bar") in my service interface. It seems that the @RemoteServiceRelativePath only allows a value relative to the module base URL...so is there some other way to accomplish what I'm trying to accomplish?

  • addSubview like modal

    - by brettr
    How can I get a UIView to transition via addSubview like the presentModalViewController does? The available animations don't seem to do this. I would use the modal but I have a navigation bar at the top and don't want to disable it. Also, the modal overlays on the navigation bar. If there is a way to have it so the modal doesn't disable the nav bar, I can go with that approach. But since it is a modal, I don't think that is possible.

  • iphone - presenting an alertview with the right orientation

    - by Mike
    I have to present an alertview when my app starts. My app supports both landscape modes. Despite the landscape mode the device is when the app starts the alertview always shows in portrait. I have tried to use the accelerometer to detect the interface orientation before the orientation notification and I have the correct orientation 2 seconds before the alertview showing. Then, I use this code to set the status bar to a different orientation, hoping the alertview will follow... [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight]; or left, depending on the landscape mode. Nothing works. Is there a way to force the alertview to respect the orientation? The point here is this: I cannot set one landscape orientation in particular for the status bar, I have to detect the orientation the device is on and then set the status bar orientation. thanks for any help.

  • NUnit-console 2.5.4 not capable of running multiple assemblies?

    - by Per Salmi
    I am having problems running tests with the command line NUnit test runner. I am using version 2.5.4 with .NET 4 on an x64 machine. Using the following line results in a failure "Could not load file or assembly 'bar' or one of its dependencies. The system cannot find the file specified." nunit-console-x86 foo.dll bar.dll /framework=4.0.30319 If I reverse the dll file names it complains about not finding 'foo' instead... It works if I run them separately like: nunit-console-x86 foo.dll /framework=4.0.30319 Also the tests of the second file works if I run: nunit-console-x86 bar.dll /framework=4.0.30319 Before upgrading our projects to 4.0 we used NUnit 2.5.2 and the same command line tool options and at that point the runner worked well with multiple assemblies. It seems like the ability to run tests on multiple files at the same time is broken... Anyone that can see the same behavior or does it work indicating that my environment is somehow broken? /Per

  • What's the best way to create a Windows Mobile application with multiple screens in C#

    - by Joseph Earl
    I am creating a Windows Mobile Application in C# and Visual Studio 2008. The application will have 5-6 main 'screens'. There will also be bar (/area) with information (e.g. a title, whether the app is busy, etc) above the screens, and a toolbar (or similar control) below the screens with 5-6 buttons (with images) to change the active screen (i.e. the screens will share the top bar and toolbar) What is the best way to implement this? Use multiple forms, and just include the toolbar and top-bar in each Use a single form and something like the Tab control (but customised) to contain the screens Something else? Keeping in mind a) memory usage and b) time to switch screens. Thanks in advance. Any links, pointers etc are much appreciated.

  • WordPress: Problem with the shortcode regex

    - by peroyomas
    This is the regular expression used for "shortcodes" in WordPress (one for the whole tag, other for the attributes). return '(.?)\[('.$tagregexp.')\b(.*?)(?:(\/))?\](?:(.+?)\[\/\2\])?(.?)'; $pattern = '/(\w+)\s*=\s*"([^"]*)"(?:\s|$)|(\w+)\s*=\s*\'([^\']*)\'(?:\s|$)|(\w+)\s*=\s*([^\s\'"]+)(?:\s|$)|"([^"]*)"(?:\s|$)|(\S+)(?:\s|$)/'; It parses stuff like [foo bar="baz"]content[/foo] or [foo /] In the WordPress trac they say it's a bit flawed, but my main problem is that it don't support shortcodes inside the attributes, like in [foo bar="[baz /]"]content[/foo] because the regex stops the main shortcode at the first appearance of a closing bracket, so in the example it renders [foo bar="[baz /] and "]content[/foo] shows as it is. Is there any way to change the regex so it bypass any ocurrence of [ with ] and its content when occurs between the opening tag or self-closing tag?

  • Avoiding symbol capture when using macros to generate functions (or other macros)

    - by Rob Lachlan
    I'm a bit confused as to exactly when symbol capture will occur with clojure macros. Suppose that I have a macro which defines a function from keywords. In this trivial example, (defmacro foo [keywd1 keywd2] `(defn ~(symbol (name keywd1)) [~(symbol (name keywd2))] (* 2 ~(symbol (name keywd2))))) I call (foo :bar :baz), and this gets expanded into (defn bar [baz] (* 2 baz)). So now the question -- can this lead to symbol capture? If so, under what circumstances? I know that it's preferred to use gensym (e.g. bar#) to prevent symbol capture, but in some cases (not many, but still) I'd like to have a pretty macro-expansion, without the auto-generated symbols. Bonus question: does the answer change if we are considering a macro that creates macros?

  • Trying to understand Java Classloading

    - by Jens
    Hello, I'm currently getting to know Java and OSGi, so I've read a few books. In one particular book the class loading is described. You can download it (free and legal) from the authors page (Neil Bartlett): OSGi Book On page 9 and 10 are this pictures: It seems like there is the possibility that our class "Foo" won't use the class "Bar" of foobar.jar, but instead class "Bar" from naughty.jar. Because of the flat and global structure of the Java classpath this could be, but as far as I know you would define a package from where you want to import a certain class: import foobar.Bar This should prevent loading the wrong class, shouldn't it? Of course assuming that the package is called "foobar".

  • Explanation of Pingdom Results

    - by Computer Guru
    Hi, I'm trying to optimize my page load times, and I'm using Pingdom to test the site response times. However, I'm not exactly sure what the various components of the "time bar" mean. Example link: http://tools.pingdom.com/fpt/?url=http://neosmart.net/forums//&id=2230361 According to them, the portion of the bar that is yellow is the time between "start" and "connect" and the portion of the bar that is green is the time between "connect" and "first byte" with the blue section being the actual transfer time (time between "first byte" and "last byte"). If I'm trying to the first two (which take very long in my case), what's the recommended course of action? Thanks.

  • Limiting landscape views in UITabBarController containing UINavigationController

    - by Spider-Paddy
    I have a tab bar application that contains navigation views in 2 of its tabs. I would like 1 view in the 1 navigation controller to allow landscape view but because of the nav bar in tab bar limitation I now have to allow landscape views for every single view in my app to make the tilt messages get passed to my app which I don't want. I thought perhaps, on the views which shouldn't go to landscape, that there might be ways to either: prevent the view change e.g. calling setOrientation:UIDeviceOrientationPortrait whenever the device goes landscape or giving the illusion that the view doesn't change e.g. presenting a modal portrait view over the rotated view Anybody have any ideas or experience that they care to share? What is the best approach here? (I don't want to now have to design a landscape view for every view just to so that I can display a portrait & landscape view for 1 view)
