  • CSS selector not resolved when using UI Binder

    - by Zhaidarbek
    Basically, I am building a horizontal navigation bar. I have following markup: <ui:style src="../common.css" type="client.resources.HomeResources.Style"> @external gwt-Anchor; .gwt-Anchor { text-decoration: none; } </ui:style> <g:HTMLPanel styleName="navbar"> <ul> <li><g:Anchor ></g:Anchor> |</li> <li><g:Anchor ></g:Anchor> |</li> <li><g:Anchor ></g:Anchor> |</li> <li><g:Anchor ></g:Anchor> |</li> <li><g:Anchor ></g:Anchor> |</li> <li><g:Anchor ></g:Anchor> |</li> <li><g:Anchor ></g:Anchor></li> </ul> common.css has following rules: ul { margin: 0; padding: 0; text-align: left; font-weight: bold; line-height: 25px; } ul li { display: inline; text-align: right; } ul li a { color: #0077C0; font-size: 12px; margin-right: 15px; padding: 4px 0 4px 5px; text-decoration: none; } ul li a:HOVER { color: #F0721C; } When using rules as defined above, everything works perfect. The problem is that I have ul elements in other parts of page, so I've added div.navbar before each rule like this: div.navbar ul{} div.navbar ul li{} etc... But those rules are not applied to ul elements inside UI Binder template. What's wrong with my code? Here is the generated HTML (normally on one line): <div class="navbar"><ul> <li><a class="gwt-Anchor">Item 1</a> |</li> <li><a class="gwt-Anchor">Item 2</a> |</li> <li><a class="gwt-Anchor">Item 3</a></li> </ul></div> RESOLVED styleName="navbar" must be styleName="{style.navbar}"

  • Scared of Calculus - Required to pass Differential Calculus as part of my Computer science major

    - by ke3pup
    Hi guys I'm finishing my Computer science degree in university but my fear of maths (lack of background knowledge) made me to leave all my maths units til' the very end which is now. i either take them on and pass or have to give up. I've passed all my programming units easily but knowing my poor maths skills won't do i've been staying clear of the maths units. I have to pass Differential Calculus and Linear Algebra first. With a help of book named "Linear Algebra: A Modern Introduction" i'm finding myself on track and i think i can pass the Linear Algebra unit. But with differential calculus i can't find a book to help me. They're either too advanced or just too simple for what i have to learn. The things i'm required to know for this units are: Set notation, the real number line, Complex numbers in cartesian form. Complex plane, modulus. Complex numbers in polar form. De Moivre’s Theorem. Complex powers and nth roots. Definition of ei? and ez for z complex. Applications to trigonometry. Revision of domain and range of a function Working in R3. Curves and surfaces. Functions of 2 variables. Level curves.Partial derivatives and tangent planes. The derivative as a difference quotient. Geometric significance of the derivative. Discussion of limit. Higher order partial derivatives. Limits of f(x,y). Continuity. Maxima and minima of f(x,y). The chain rule. Implicit differentiation. Directional derivatives and the gradient. Limit laws, l’Hoˆpital’s rule, composition law. Definition of sinh and cosh and their inverses. Taylor polynomials. The remainder term. Taylor series. Is there a book to help me get on track with the above? Being a student i can't buy too many books hence why i'm looking for a book that covers topics I need to know. The University library has a fairly limited collection which i took as loan but didn't find useful as it was too complex.

  • Boost Python - Limits to the number of arguments when wrapping a function

    - by Derek
    I'm using Boost Python to wrap some C++ functions that I've created. One of my C++ functions contains 22 arguments. Boost complains when I try to compile my solution with this function, and I'm trying to figure out if it is just because this function has too many arguments. Does anyone know if such a limit exists? I've copied the error I'm getting below, not the code because I figure someone either knows the answer to this or not - and if there is no limit then I'll just try to figure it out myself. Thanks very much in advance! Here is a copy of the beginning of the error message I receive... 1>main.cpp 1>c:\cpp_ext\boost\boost_1_47\boost\python\make_function.hpp(76): error C2780: 'boost::mpl::vector17<RT,most_derived<Target,ClassT>::type&,T0,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14> boost::python::detail::get_signature(RT (__thiscall ClassT::* )(T0,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14) volatile const,Target *)' : expects 2 arguments - 1 provided 1>c:\cpp_ext\boost\boost_1_47\boost\python\signature.hpp(236) : see declaration of 'boost::python::detail::get_signature' And eventually I get about a hundred copies of error messages very much resembling this one: 1>c:\cpp_ext\boost\boost_1_47\boost\python\make_function.hpp(76): error C2784: 'boost::mpl::vector17<RT,ClassT&,T0,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14> boost::python::detail::get_signature(RT (__thiscall ClassT::* )(T0,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14) volatile const)' : could not deduce template argument for 'RT (__thiscall ClassT::* )(T0,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14) volatile const' from 'std::string (__cdecl *)(const std::string &,jal::date::JULIAN_DATE,const std::string &,const std::string &,int,const std::string &,const std::string &,const std::string &,const std::string &,const std::string &,const std::string &,int,const std::string &,const std::string &,int,const std::string &,const std::string &,const std::string &,const std::string &,const std::string &,int,const std::string &)' 1> c:\cpp_ext\boost\boost_1_47\boost\python\signature.hpp(218) : see declaration of 'boost::python::detail::get_signature' 1>c:\cpp_ext\boost\boost_1_47\boost\python\make_function.hpp(76): error C2780: 'boost::mpl::vector17<RT,most_derived<Target,ClassT>::type&,T0,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14> boost::python::detail::get_signature(RT (__thiscall ClassT::* )(T0,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14) volatile,Target *)' : expects 2 arguments - 1 provided 1> c:\cpp_ext\boost\boost_1_47\boost\python\signature.hpp(236) : see declaration of 'boost::python::detail::get_signature'

  • Using in app purchase to unlock features vs. using free & paid app versions for iPhone

    - by yabada
    I have an app that I was going to release as a free (lite) version with some of the total functionality and a paid full version with advanced functionality. Now, with in app purchase for free apps I am thinking of going that route with the ability to unlock features as needed. I'm not talking about a trial version that expires.I want people to be able to try out the app and get an idea of the interface and functionality before deciding to purchase the full functionality of each major section of the app, basically. Here's an analogy of what my app would be like. Let's say you have a cooking app that teaches you to cook in different styles. There could be major section for French, Italian, and Chinese. Each section could have some rudiments unlocked in the free app so users can see the UI and basics of the functionality. Then, the user could decide to purchase each major section (or not) individually with in app purchase or buy the full versioned app (with the free/paid model). One concern I have with offering a free app with in app purchase would be with feedback. I would be very clear in my description in the app store that there is in app purchase for full features but I'm worried that less serious users could/would leave negative feedback. I suppose that's always a risk but curious about any experience with this. It also seems that it could be a whole lot more complicated keeping track of what portions of the app are locked and unlocked with in app purchase. I know I'd have to have all the code for the full functionality and "lock" the portions that haven't been purchased. How do people usually lock portions of their code? I'm not talking about the process of purchasing (I've read the In App Purchase Programming Guide) but after the purchase has been made. Would I just keep track of what the user has purchased and put conditionals on the sections that are initially locked? Or is there another way to do this as well? My instinct is for the in app purchase (particularly since users could purchase the major sections that they want individually).

  • WPF customer control and direct content support

    - by Mmarquee
    I am fairly new to WPF, and am a bit stuck, so any help would be appreciated. I am trying to write WPF custom control that encapsulates several elements of functionality that I already having working (i.e sorting, filtering, standard menus, etc.), but in a nice neat package to avoid repetition. Anyway I have created the custom control (based on control), and then have the following in the Generic.Xaml <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:Controls.ListViewExtended"> <Style TargetType="{x:Type local:ListViewExtended}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type local:ListViewExtended}"> <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}"> <ListView> <ListView.View> <GridView> <!-- Content goes here --> </GridView> </ListView.View> </ListView> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> </ResourceDictionary> When I try to add GridViewColumns (or any control really), as below ... <elv:ListViewExtended> <GridView> <GridViewColumn Width="140" Header="Column 1" /> <GridViewColumn Width="140" Header="Column 2" /> <GridViewColumn Width="140" Header="Column 3" /> </GridView> </elv:ListViewExtended> I get the "... does not support direct content" error. I have created a dependancy property (again below) that allows the adding of GridView, but it still doesn't work. public static DependencyProperty GridViewProperty; public static string GridViewHeader(DependencyObject target) { return (string)target.GetValue(GridViewProperty); } public static void GridViewHeader(DependencyObject target, string value) { target.SetValue(GridViewProperty, value); } Thanks in advance

  • json problems with making a ruby on rails application

    - by Prince Merdz
    So I'm using Bitnami to learn Ruby on Rails. I have also previously tried the manual installation for ruby and rails and was met by the same problem so I thought I should try first the easy package deal of Bitnami. Anyway my problem with json is that it causes the bundle install to fail. First the auto bundle install that rails new does fails because of an ssl error. Which is easily solved by changing the source in the gemfile which is https to http. However when I try to bundle install it does another error when it tries to install json.

  • WPF - How do I get an object that is bound to a ListBoxItem back

    - by JonBlumfeld
    Hi there here is what I would like to do. I get a List of objects from a database and bind this list to a ListBox Control. The ListBoxItems consist of a textbox and a button. Here is what I came up with. Up to this point it works as intended. The object has a number of Properties like ID, Name. If I click on the button in the ListBoxItem the Item should be erased from the ListBox and also from the database... <ListBox x:Name="taglistBox"> <ListBox.ItemContainerStyle> <Style TargetType="{x:Type ListBoxItem}"> <Setter Property="HorizontalAlignment" Value="Stretch"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ListBoxItem"> <ContentPresenter HorizontalAlignment="Stretch"/> </ControlTemplate> </Setter.Value> </Setter> <Setter Property="Tag" Value="{Binding TagSelf}"></Setter> </Style> </ListBox.ItemContainerStyle> <ListBox.ItemTemplate> <DataTemplate> <Grid HorizontalAlignment="Stretch"> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition/> </Grid.ColumnDefinitions> <Button Grid.Column="0" Name="btTag" VerticalAlignment="Center" Click="btTag_Click" HorizontalAlignment="Left"> <Image Width="16" Height="16" Source="/WpfApplication1;component/Resources/104.png"/> </Button> <TextBlock Name="tbtagBoxTagItem" Margin="5" Grid.Column="1" Text="{Binding Name}" VerticalAlignment="Center" /> </Grid> </DataTemplate> </ListBox.ItemTemplate> </ListBox> The Textblock.Text is bound to object.Name and the ListBoxItem.Tag to object.TagSelf (which is just a copy of the object itself). Now my questions If I click the button in the listboxItem how do I get the listboxitem and the object bound to it back. In order to delete the object from the database I have to retrieve it somehow. I tried something like ListBoxItem lbi1 = (ListBoxItem)(taglistBox.ItemContainerGenerator.ContainerFromItem(taglistBox.Items.CurrentItem)); ObjectInQuestion t = (ObjectInQuestion) lbi1.Tag; Is there a way to automatically update the contents of the ListBox if the Itemssource changes? Right now I'm achieving that by taglistBox.ItemsSource = null; taglistBox.ItemsSource = ObjectInQuestion; I'd appreciate any help you can give :D Thanks in advance

  • Is Ogre's use of Exceptions a good way of using them?

    - by identitycrisisuk
    I've managed to get through my C++ game programming career so far virtually never touching exceptions but recently I've been working on a project with the Ogre engine and I'm trying to learn properly. I've found a lot of good questions and answers here on the general usage of C++ exceptions but I'd like to get some outside opinions from here on whether Ogre's usage is good and how best to work with them. To start with, quoting from Ogre's documentation of it's own Exception class: OGRE never uses return values to indicate errors. Instead, if an error occurs, an exception is thrown, and this is the object that encapsulates the detail of the problem. The application using OGRE should always ensure that the exceptions are caught, so all OGRE engine functions should occur within a try{} catch(Ogre::Exception& e) {} block. Really? Every single Ogre function could throw an exception and be wrapped in a try/catch block? At present this is handled in our usage of it by a try/catch in main that will show a message box with the exception description before exiting. This can be a bit awkward for debugging though as you don't get a stack trace, just the function that threw the error - more important is the function from our code that called the Ogre function. If it was an assert in Ogre code then it would go straight to the code in the debugger and I'd be able to find out what's going on much easier - I don't know if I'm missing something that would allow me to debug exceptions already? I'm starting to add a few more try/catch blocks in our code now, generally thinking about whether it matters if the Ogre function throws an exception. If it's something that will stop everything working then let the main try/catch handle it and exit the program. If it's not of great importance then catch it just after the function call and let the program continue. One recent example of this was building up a vector of the vertex/fragment program parameters for materials applied to an entity - if a material didn't have any parameters then it would throw an exception, which I caught and then ignored as it didn't need to add to my list of parameters. Does this seem like a reasonable way of dealing with things? Any specific advice for working with Ogre is much appreciated.

  • Advice on displaying and allowing editing of data using ASP.NET MVC?

    - by Remnant
    I am embarking upon my first ASP.NET MVC project and I would like to get some input on possible ways to display database data and general best practice. In short, the body of my webpage will show data from my database in a table like format, with each table row showing similar data. For example: Name Age Position Date Joined Jon Smith 23 Striker 18th Mar 2005 John Doe 38 Defender 3rd Jan 1988 In terms of functionality, primarily I’d like to give the user the ability to edit the data and, after the edit, commit the edit to the database and refresh the view.The reason I want to refresh the view is because the data is date ordered and I will need to re-sort if the user edits a date field. My main question is what architecture / tools would be best suited to this fulfil my requirements at a high level? From the research I have done so far my initial conclusions were: ADO.NET for data retrieval. This is something I have used before and feel comfortable with. I like the look of LINQ to SQL but don’t want to make the learning curve any steeper for my first outing into MVC land just yet. Partial Views to create a template and then iterate through a datatable that I have pulled back from my database model. jQuery to allow the user to edit data in the table, error check edited data entries etc. Also, my intial view was that caching the data would not be a key requirement here. The only field a user will be able to update is the field and, if they do, I will need to commit that data to the database immediately and then refresh the view (as the data is date sorted). Any thoughts on this? Alternatively, I have seen some jQuery plug-ins that emulate a datagrid and provide associated functionality. My first thoughts are that I do not need all the functionality that comes with these plug-ins (e.g. zebra striping, ability to sort by column using sort glyph in column headers etc .) and I don’t really see any benefit to this over and above the solution I have outlined above. Again, is there reason to reconsider this view? Finally, when a user edits a date , I will need to refresh the view. In order to do this I had been reading about Html.RenderAction and this seemed like it may be a better option than using Partial Views as I can incorporate application logic into the action method. Am I right to consider Html.RenderAction or have I misunderstood its usage? Hope this post is clear and not too long. I did consider separate posts for each topic (e.g. Partial View vs. Html.RenderAction, when to use jQury datagrid plug-in) but it feels like these issues are so intertwined that they need to be dealt with in contect of each other. Thanks

  • XSLT Document function returns empty result on Maven POM

    - by user328618
    Greetings! I want to extract some properties from different Maven POMs in a XSLT via the document function. The script itself works fine but the document function returns an empty result for the POM as long as I have the xmlns="http://maven.apache.org/POM/4.0.0" in the project tag. If I remove it, everything works fine. Any idea how the make this work while leaving the xmlns attribute where it belongs or why this doesn't work with the attribute in place? Here comes the relevant portion of my XSLT: <xsl:template match="abcs"> <xsl:variable name="artifactCoordinate" select="abc"/> <xsl:choose> <xsl:when test="document(concat($artifactCoordinate,'-pom.xml'))"> <abc> <ID><xsl:value-of select="$artifactCoordinate"/></ID> <xsl:copy-of select="document(concat($artifactCoordinate,'-pom.xml'))/project/properties"/> </abc> </xsl:when> <xsl:otherwise> <xsl:message terminate="yes"> Transformation failed: POM "<xsl:value-of select="concat($artifactCoordinate,'-pom.xml')"/>" doesn't exist. </xsl:message> </xsl:otherwise> </xsl:choose> And, for completeness, a POM extract with the "bad" attribute: <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <!-- ... --> <properties> <proalpha.version>[5.2a]</proalpha.version> <proalpha.openedge.version>[10.1B]</proalpha.openedge.version> <proalpha.optimierer.version>[1.1]</proalpha.optimierer.version> <proalpha.sonic.version>[7.6.1]</proalpha.sonic.version> </properties> </project>

  • Fixed point math in c#?

    - by x4000
    Hi there, I was wondering if anyone here knows of any good resources for fixed point math in c#? I've seen things like this (http://2ddev.72dpiarmy.com/viewtopic.php?id=156) and this (http://stackoverflow.com/questions/79677/whats-the-best-way-to-do-fixed-point-math), and a number of discussions about whether decimal is really fixed point or actually floating point (update: responders have confirmed that it's definitely floating point), but I haven't seen a solid C# library for things like calculating cosine and sine. My needs are simple -- I need the basic operators, plus cosine, sine, arctan2, PI... I think that's about it. Maybe sqrt. I'm programming a 2D RTS game, which I have largely working, but the unit movement when using floating-point math (doubles) has very small inaccuracies over time (10-30 minutes) across multiple machines, leading to desyncs. This is presently only between a 32 bit OS and a 64 bit OS, all the 32 bit machines seem to stay in sync without issue, which is what makes me think this is a floating point issue. I was aware from this as a possible issue from the outset, and so have limited my use of non-integer position math as much as possible, but for smooth diagonal movement at varying speeds I'm calculating the angle between points in radians, then getting the x and y components of movement with sin and cos. That's the main issue. I'm also doing some calculations for line segment intersections, line-circle intersections, circle-rect intersections, etc, that also probably need to move from floating-point to fixed-point to avoid cross-machine issues. If there's something open source in Java or VB or another comparable language, I could probably convert the code for my uses. The main priority for me is accuracy, although I'd like as little speed loss over present performance as possible. This whole fixed point math thing is very new to me, and I'm surprised by how little practical information on it there is on google -- most stuff seems to be either theory or dense C++ header files. Anything you could do to point me in the right direction is much appreciated; if I can get this working, I plan to open-source the math functions I put together so that there will be a resource for other C# programmers out there. UPDATE: I could definitely make a cosine/sine lookup table work for my purposes, but I don't think that would work for arctan2, since I'd need to generate a table with about 64,000x64,000 entries (yikes). If you know any programmatic explanations of efficient ways to calculate things like arctan2, that would be awesome. My math background is all right, but the advanced formulas and traditional math notation are very difficult for me to translate into code.

  • The most efficient method of drawing multiple quads in OpenGL

    - by CPatton
    I'm not very keen with OpenGL and I was wondering if someone could give me some insight on this. I'm a 'seasoned' programmer, I've read the redbook about VBOs and the like, but I was wondering from a more experienced person about the best/most efficient way of achieving this. I've been producing this 2d tile-based game engine to be used in several projects. I have a class called "ScreenObject" which is mainly composed of a Dictionary<Point, Tile> The Point key is to show where to render the Tile on the screen, and the Tile contains one or more textures to be drawn at that point. This ScreenObject is where the tiles will be modified, deleted, added, etc.. My original method of drawing the tiles in the testing I've done was to iterate through the ScreenObject and draw each quad at each location separately. From what I've read, this is a massive waste of resources. It wasn't horribly slow in the testing, but after I've completed the animation classes and effect classes, I'm sure it would be extremely slow. And one last thing, if you wouldn't mind.. As I said before, the Tile class can contain multiple textures to be drawn at the Point location on the screen. I recognize possibly two options for me here. Either add a quad at that location for each texture to be drawn, or, somehow.. use a multiple texture for the same quad (if it's possible). Even if each tile contained one texture only, that would be 64 quads to be drawn on the screen. Most of the tiles will contain 2-5 textures, so the number of total quads would increase dramatically with this method. Would it be feasible to add a quad for each new texture, or am I ignoring a better way to do this? Just need some help understanding this if you don't mind :) I've tried to be as concise as possible, and I'd greatly appreciate any responses.. and even some criticism. Programming is often a learning process and one who develops seems to never stops learning. Thanks for your time.

  • active_scaffold routing error

    - by Elizabeth Buckwalter
    If you haven't seen my question yesterday, this is my second rails app. The first went nice and smooth, but this one keeps giving me one random error after another. I installed active_scaffold for this app as well as the last app (the first error, instead of using script/install plugin git://active_scaffold repository, I did script/install plugin http://active_scaffold repository.) I didn't want to spell out basic CRUD on minor models. After the install problems, (before I found the http solution from a windows user when I'm on Linux) I thought I'd try out Hobo. Well, Hobo updated actionmailer, actionpack, activerecord, activeresource, and installed rack. Rails isn't even using the updated versions. But as you can see at the bottom of the trace it's using rack. I have a feeling it has something to do with my futzing around with installing Hobo which I uninstalled. Thanks in advanced. [Edit] I had asked the question over at the ActiveScaffold Group the answer (if you don't want to follow the link) was that this line needed to be added to routes: map.resources :modelName, :active_scaffold => true It doesn't entirely answer my question, since the documentation said nothing about changing routes. But, it works. [/Edit] ActionController::RoutingError in Departments#index Showing vendor/plugins/active_scaffold/frontends/default/views/_list_header.html.erb where line #8 raised: No route matches {:_method=:get, :action="show_search", :controller="departments"} Extracted source (around line #8): 5: <% next if controller.respond_to? link.security_method and !controller.send(link.security_method) -%> 6: <% next if link.action == 'new' && params[:nested].nil? && active_scaffold_config.list.always_show_create %> 7: <% next if link.action == 'show_search' && active_scaffold_config.list.always_show_search %> 8: <%= render_action_link(link, new_params) -%> 9: <% end -%> 10: 11: <%= loading_indicator_tag(:action => :table) %> Trace of template inclusion: vendor/plugins/active_scaffold/frontends/default/views/list.html.erb Full Trace It was taking forever to format it.

  • "Phased" execution of functions in javascript

    - by FK82
    Hey there! This is my first post on stackoverflow, so please don't flame me too hard if I come across like a total nitwit or if I'm unable ot make myself perfectly clear. :-) Here's my problem: I'm trying to write a javascript function that "ties" two functions to another by checking the first one's completion and then executing the second one. The easy solution to this obviously would be to write a meta function that calls both functions within it's scope. However, if the first function is asynchronous (specifically an AJAX call) and the second function requires the first one's result data, that simply won't work. My idea for a solution was to give the first function a "flag", i.e. making it create a public property "this.trigger" (initialized as "0", set to "1" upon completion) once it is called; doing that should make it possible for another function to check the flag for its value ([0,1]). If the condition is met ("trigger == 1") the second function should get called. The following is an abstract example code that I have used for testing: <script type="text/javascript" > /**/function cllFnc(tgt) { //!! first function this.trigger = 0 ; var trigger = this.trigger ; var _tgt = document.getElementById(tgt) ; //!! changes the color of the target div to signalize the function's execution _tgt.style.background = '#66f' ; alert('Calling! ...') ; setTimeout(function() { //!! in place of an AJAX call, duration 5000ms trigger = 1 ; },5000) ; } /**/function rcvFnc(tgt) { //!! second function that should get called upon the first function's completion var _tgt = document.getElementById(tgt) ; //!! changes color of the target div to signalize the function's execution _tgt.style.background = '#f63' ; alert('... Someone picked up!') ; } /**/function callCheck(obj) { //alert(obj.trigger ) ; //!! correctly returns initial "0" if(obj.trigger == 1) { //!! here's the problem: trigger never receives change from function on success and thus function two never fires alert('trigger is one') ; return true ; } else if(obj.trigger == 0) { return false ; } } /**/function tieExc(fncA,fncB,prms) { if(fncA == 'cllFnc') { var objA = new cllFnc(prms) ; alert(typeof objA + '\n' + objA.trigger) ; //!! returns expected values "object" and "0" } //room for more case definitions var myItv = window.setInterval(function() { document.getElementById(prms).innerHTML = new Date() ; //!! displays date in target div to signalize the interval increments var myCallCheck = new callCheck(objA) ; if( myCallCheck == true ) { if(fncB == 'rcvFnc') { var objB = new rcvFnc(prms) ; } //room for more case definitions window.clearInterval(myItv) ; } else if( myCallCheck == false ) { return ; } },500) ; } </script> The HTML part for testing: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/strict.dtd > <html> <head> <script type="text/javascript" > <!-- see above --> </script> <title> Test page </title> </head> <body> <!-- !! testing area --> <div id='target' style='float:left ; height:6em ; width:8em ; padding:0.1em 0 0 0; font-size:5em ; text-align:center ; font-weight:bold ; color:#eee ; background:#fff;border:0.1em solid #555 ; -webkit-border-radius:0.5em ;' > Test Div </div> <div style="float:left;" > <input type="button" value="tie calls" onmousedown="tieExc('cllFnc','rcvFnc','target') ;" /> </div> <body> </html> I'm pretty sure that this is some issue with javascript scope as I have checked whether the trigger gets set to "1" correctly and it does. Very likely the "checkCall()" function does not receive the updated object but instead only checks its old instance which obviously never flags completion by setting "this.trigger" to "1". If so I don't know how to address that issue. Anyway, hope someone has an idea or experience with this particular kind of problem. Thanks for reading! FK

  • Calculating multiple column average in SQLite3

    - by Benjamin Oakes
    I need to average some values in a row-wise fashion, rather than a column-wise fashion. (If I were doing a column-wise average, I could just use avg()). My specific application of this requires me ignore NULLs in averaging. It's pretty straightforward logic, but seems awfully difficult to do in SQL. Is there an elegant way of doing my calculation? I'm using SQLite3, for what it's worth. Details If you need more details, here's an illustration: I have a a table with a survey: | q1 | q2 | q3 | ... | q144 | |----|-------|-------|-----|------| | 1 | 3 | 7 | ... | 2 | | 4 | 2 | NULL | ... | 1 | | 5 | NULL | 2 | ... | 3 | (Those are just some example values and simple column names. The valid values are 1 through 7 and NULL.) I need to calculate some averages like so: q7 + q33 + q38 + q40 + ... + q119 / 11 as domain_score_1 q10 + q11 + q34 + q35 + ... + q140 / 13 as domain_score_2 ... q2 + q5 + q13 + q25 + ... + q122 / 12 as domain_score_14 ...but i need to pull out the nulls and average based on the non-nulls. So, for domain_score_1 (which has 11 items), I would need to do: Input: 3, 5, NULL, 7, 2, NULL, 3, 1, 5, NULL, 1 (3 + 5 + 7 + 2 + 3 + 1 + 5 + 1) / (11 - 3) 27 / 8 3.375 A simple algorithm I'm considering is: Input: 3, 5, NULL, 7, 2, NULL, 3, 1, 5, NULL, 1 Coalesce each value to 0 if NULL: 3, 5, 0, 7, 2, 0, 3, 1, 5, 0, 1 Sum: 27 Get the number of non-zeros by converting values 0 to 1 and sum: 3, 5, 0, 7, 2, 0, 3, 1, 5, 0, 1 1, 1, 0, 1, 1, 0, 1, 1, 1, 0, 1 8 Divide those two numbers 27 / 8 3.375 But that seems like a lot more programming than this should take. Is there an elegant way of doing this that I'm not aware of? Update: Unless I'm misunderstanding something, avg() won't work for this. Example of what I would want to do: select avg(q7, q33, q38, ..., q119) from survey; Output: SQL error near line 3: wrong number of arguments to function avg()

  • Creating a bundle - What's going wrong?

    - by joeylange
    Hello everyone, I've got a relatively simple one here. I'm making bundles to live inside the Resources folder of my application (and possibly in the Application Support folder). These bundles will contain template information for the data the application handles. I've constructed a bundle, with extension "booksprintstyle", and the directory structure is up to spec. I have an Info.plist all set and I think I've filled in all the values I need to. Do I need to change something in my App to have these folders-with-extensions recognized as bundle files, or am I missing something in my bundle structure? I noticed that some bundles have a file called PkgInfo; is that important? Below is the Info.plist from my bundle. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>CFBundleDevelopmentRegion</key> <string>English</string> <key>CFBundleGetInfoString</key> <string>1.0, Copyright © 2009 Joey Lange</string> <key>CFBundleIdentifier</key> <string>net.atherial.books.exporter.printingpress.printstyle</string> <key>CFBundleInfoDictionaryVersion</key> <string>6.0</string> <key>CFBundleName</key> <string>Books Print Style - Generic</string> <key>CFBundlePackageType</key> <string>BNDL</string> <key>CFBundleShortVersionString</key> <string>1.0</string> <key>CFBundleSignature</key> <string>????</string> <key>CFBundleDisplayName</key> <string>Books Print Style - Generic</string> <key>NSHumanReadableCopyright</key> <string>Copyright © 2009 Joey Lange</string> <key>CFBundleVersion</key> <string>1.0</string> </dict> </plist>

  • WPF 4 Datagrid with ComboBox

    - by Doug
    I have a WPF 4 app with a ComboBox embedded in a DataGrid. The ComboBox is in a template column that displays the combobox when in edit mode but just a TextBlock otherwise. If I edit the cell and pick a new value from the combobox, when leaving the cell, the TextBlock in view mode does not reflect the new value. Ultimately, the new value gets saved and is displayed when the window is refreshed but it does not happen while still editing in the grid. Here are the parts that are making this more complicated. The grid and the combobox are bound to different ItemsSource from the EnityFramework which is tied to my database. For this problem, the grid is displaying project members. The project member name can be picked from the combobox which gives a list of all company employees. Any ideas on how to tie the view mode of the DataGridColumnTemplate to the edit value when they are pointing to different DataSources? Relevant XAML <Window.Resources> <ObjectDataProvider x:Key="EmployeeODP" /> </Window.Resources> <StackPanel> <DataGrid Name="teamProjectGrid" AutoGenerateColumns="false" ItemsSource="{Binding Path=ProjectMembers}" <DataGrid.Columns> <DataGridTemplateColumn Header="Name" x:Name="colProjectMember"> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Path=ProjectMemberFullName}" /> </DataTemplate> </DataGridTemplateColumn.CellTemplate> <DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <ComboBox x:Name="ProjectMemberCombo" IsReadOnly="True" DisplayMemberPath="FullName" SelectedValue="{Binding Path=Employee}" ItemsSource="{Binding Source={StaticResource EmployeeODP}}" /> </DataTemplate> </DataGridTemplateColumn.CellEditingTemplate> </DataGridTemplateColumn> <DataGridTextColumn x:Name="colProjectRole" Binding="{Binding Path=ProjectRole}" Header="Role" /> </DataGrid.Columns> </DataGrid> </StackPanel> Relevant Code Behind this.DataContext = new MyEntityLibrary.MyProjectEntities(); ObjectDataProvider EmployeeODP= (ObjectDataProvider)FindResource("EmployeeODP"); if (EmployeeODP != null) { EmployeeODP.ObjectInstance = this.DataContext.Employees; }

  • How can I use Web Services Core to send a complex type as a parameter to a SOAP API method

    - by Matthew Brindley
    I don't do much Cocoa programming, so I'm probably missing something obvious, so please excuse the basic question. I have a SOAP method that expects a complex type as a paramater. Here's some WSDL: <s:element name="SaveTestResult"> <s:complexType> <s:sequence> <s:element minOccurs="0" maxOccurs="1" name="result" type="tns:TestItemResponse" /> </s:sequence> </s:complexType> </s:element> Here's the definition of the complex type "TestItemResponse": <s:complexType name="TestItemResponse"> <s:sequence> <s:element minOccurs="1" maxOccurs="1" name="TestItemRequestId" type="s:int" /> <s:element minOccurs="1" maxOccurs="1" name="ExternalId" type="s:int" /> <s:element minOccurs="0" maxOccurs="1" name="ApiId" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="InboxGuid" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="SpamResult" type="tns:SpamResult" /> <s:element minOccurs="0" maxOccurs="1" name="ResultImageSet" type="tns:ResultImageSet" /> <s:element minOccurs="1" maxOccurs="1" name="ExclusiveUseMailAccountId" type="s:int" /> <s:element minOccurs="1" maxOccurs="1" name="State" type="tns:TestItemResponseState" /> <s:element minOccurs="0" maxOccurs="1" name="ErrorShortDescription" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="ErrorFullDescription" type="s:string" /> </s:sequence> </s:complexType> I've been using Web Services Core to call a SOAP API method that requires a simple string param, that works great. That same method returns a complex type which WSC converted into nested NSDictionaries, so no problems there. So I assumed I'd be able to convert my local TestItemResponse class into an NSDictionary and then use that as the complex type param. It almost worked, but unfortunately WSC set the object's type as "Dictionary", instead of "TestItemResponse", and the server complained. <TestItemResponse xsi:type=\"SOAP-ENC:Dictionary\"> <ErrorFullDescription xsi:type=\"xsd:string\">foo</ErrorFullDescription> ... I can't seem to find anything that allows you to override the type WSC assigns to the element in the SOAP XML. I've been using code adapted from here, I'm happy to list it, it's just quite long and this is already the longest SO question I've ever posted.

  • Can I Number a GroupTemplate or ItemTemplate?

    - by Atomiton
    I would like to use a GroupTemplate to separate a list of items into groups. However, I need each Group to be numbered sequentially so I can link to them and implement some JS paging. I'm binding to an IEnumerable Here's some pseudo code. I would like the output to look like this: <a href="#group1">Go to Group 1<a> <a href="#group2">Go to Group 2<a> <a href="#group3">Go to Group 3<a> <ul id="group1"> <li>Item</li> <li>Item</li> <li>Item</li> </ul> <ul id="group2"> <li>Item</li> <li>Item</li> <li>Item</li> </ul> <ul id="group3"> <li>Item</li> <li>Item</li> <li>Item</li> </ul> Is this easy to do in a ListView, using GroupTemplate and ItemTemplate? <asp:ListView ID="lv" runat="server" GroupPlaceholderID="groupPlaceholder"> <LayoutTemplate> <asp:PlaceHolder ID="groupPlaceholder" runat="server"></asp:PlaceHolder> </LayoutTemplate> <GroupTemplate> <ul id="<!-- group-n goes here -->"> <asp:PlaceHolder ID="itemPlaceholder" runat="server"></asp:PlaceHolder> </ul> </GroupTemplate> <ItemTemplate> <li>Item</li> </ItemTemplate> </asp:ListView> I can get the number of groups to do the links at the top from the Datasource and basic math, but how do I get id="groupN" number into the template?

  • CodeGolf: Brothers

    - by John McClane
    Hi guys, I just finished participating in the 2009 ACM ICPC Programming Conest in the Latinamerican Finals. These questions were for Brazil, Bolivia, Chile, etc. My team and I could only finish two questions out of the eleven (not bad I think for the first try). Here's one we could finish. I'm curious to seeing any variations to the code. The question in full: ps: These questions can also be found on the official ICPC website available to everyone. In the land of ACM ruled a greeat king who became obsessed with order. The kingdom had a rectangular form, and the king divided the territory into a grid of small rectangular counties. Before dying the king distributed the counties among his sons. The king was unaware of the rivalries between his sons: The first heir hated the second but not the rest, the second hated the third but not the rest, and so on...Finally, the last heir hated the first heir, but not the other heirs. As soon as the king died, the strange rivaly among the King's sons sparked off a generalized war in the kingdom. Attacks only took place between pairs of adjacent counties (adjacent counties are those that share one vertical or horizontal border). A county X attacked an adjacent county Y whenever X hated Y. The attacked county was always conquered. All attacks where carried out simultanously and a set of simultanous attacks was called a battle. After a certain number of battles, the surviving sons made a truce and never battled again. For example if the king had three sons, named 0, 1 and 2, the figure below shows what happens in the first battle for a given initial land distribution: INPUT The input contains several test cases. The first line of a test case contains four integers, N, R, C and K. N - The number of heirs (2 <= N <= 100) R and C - The dimensions of the land. (2 <= R,C <= 100) K - Number of battles that are going to take place. (1 <= K <= 100) Heirs are identified by sequential integers starting from zero. Each of the next R lines contains C integers HeirIdentificationNumber (saying what heir owns this land) separated by single spaces. This is to layout the initial land. The last test case is a line separated by four zeroes separated by single spaces. (To exit the program so to speak) Output For each test case your program must print R lines with C integers each, separated by single spaces in the same format as the input, representing the land distribution after all battles. Sample Input: Sample Output: 3 4 4 3 2 2 2 0 0 1 2 0 2 1 0 1 1 0 2 0 2 2 2 0 0 1 2 0 0 2 0 0 0 1 2 2 Another example: Sample Input: Sample Output: 4 2 3 4 1 0 3 1 0 3 2 1 2 2 1 2
