  • How to add and relate a node within the parent nodes add form in Drupal.

    - by Espen Christensen
    Hi, I want to accomplish the following scenario in Drupal: You have 2 content-types. Lets say, an application-form for a lisence, and a content-type for persons. Then when you go to add a lisence in the "node/add" submission form in Drupal, i would like to add a relative number of persons that would be related to this lisence, and only this lisence. Say you would like to apply for a lisence, and relate 4 persons to this lisence, then insted of creating the lisence and then create the 4 persons and relate them to the lisence, i would like to do this "inline". So when i add a lisence, there would be a way to add 1 or more persons that would relate to the lisence node. Is this possible, and if so how? I have been looking at the node reference module, and that manages to reference a node to another, but not to add them inline with the other. With the web-development framework Django, there is a way to this with something called "inline-editing", where you get the content-type fields inside another content-type creation form. There you bind them togheter with a ForeignKey. Anybody know of something simular in Drupal, if not, is it another way to achive something simular, that would be as user-friendly?

  • Create a UIView Subclass that calls a delegate function whenever it's parent viewController appears?

    - by Andrew Johnson
    UIViewControllers have viewWillAppear, viewDidDisappear, etc. delegate methods. I would like to create a UIView subclass that can be added to a viewController's view, and when that UIViewController apears or disappears, a delegate function is called. I could easily do this by putting function calls in the UIViewController viewWillAppear/viewWillDisappear delegate functions, but how can I encapsulate this behavior in the UIView?

  • Clarification needed: How does .NET runtime resolve assembly references from parent folder?

    - by aoven
    I have the following output structure of executables in my solution: %ProgramFiles% | +-[MyAppName] | +-[Client] | | | +-(EXE & several DLL assemblies) | +-[Common] | | | +-[Schema Assemblies] | | | | | +-(several DLL assemblies) | | | +-(several DLL assemblies) | +-[Server] | +-(EXE & several DLL assemblies) Each project in solution references different DLL assemblies, some of which are outputs from other projects in solution, and others are plain 3rd-party assemblies. For example, [Client] EXE might reference an assembly in [Common], which is in a different directory branch. All references have "Copy Local" set to false, to mirror the layout of the files in the final installed application. Now, if I take a look at reference properties in the Visual Studio IDE, I see that "Path" of every reference is absolute and that it corresponds to the actual output location of the assembly. That's understandable and correct. As expected, solution compiles and runs just fine. What I don't understand is, why everything seems to work even when I close the IDE, rename the [MyAppName] directory and run the [Client] EXE manually? How does the runtime find the assemblies if the reference paths aren't the same as they were at the time of linking? To be clear - this is actually exactly what I'm after: a semi-dispersed set of application files that run fine regardless of where the [MyAppName] directory is located or even what it's named. I'd just like to know, how and why this works without any specific path resolution on my part. I've read the answers to this similar question, but I still don't get it. Help much appreciated!

  • Can a web app in xul:iframe access functions from its parent XUL file?

    - by oskar
    I want to deploy a web app as a self-contained program using XULRunner. I'm simply loading it in a xul:iframe tag within the main XUL file. It works, but I want the web app to have access to XUL components, specifically nsiFilePicker. My tentative solution is to run the xul:iframe with escalated privileges (by omitting the "type" attribute), wait for the xul:iframe to load, then define a javascript function that the web app will then call. <window id="main" width="800" height="600" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <iframe id="contentview" src="web/index.html" flex="1"/> <script> //listen for XUL window to load window.addEventListener("load",Listen,false); function Listen() { var frame = document.getElementById("contentview"); frame.addEventListener("DOMContentLoaded", DomLoadedEventHandler, true); } //listen for iframe to load function DomLoadedEventHandler() { //set function in iframe called testMe() var frame = document.getElementById("contentview"); frame.contentWindow.testMe = function () { alert("This is a test"); }; } </script> </window> ...and then in the index.html file of the web app... <script> testMe(); </script> This doesn't seem to work. Does anyone have any suggestions?

  • How can I pass a mouse click to a parent control?

    - by grimus
    In a Silverlight 2 app, I am using Rectangles on a Canvas to draw a representation of data. I would like to have mouse clicks on the Rectangles be passed on to the control that owns the Canvas. I would also like to be able to show a tooltip with a summary of the data when the mouse is over a Rectangle. So far I've only been able to achieve one item or the other. If I make the Rectangles have their IsHitTestVisible property = false, the tooltips don't work, but the owning control will receive the mouse clicks. If I set it to true, then tooltips do work, but the clicks don't get passed on. Is there a way to have a Silverlight item be IsHitTestvisible = true, and pass on the mouse clicks?

  • JavaScript: Given an offset and substring length in an HTML string, what is the parent node?

    - by Bungle
    My current project requires locating an array of strings within an element's text content, then wrapping those matching strings in <a> elements using JavaScript (requirements simplified here for clarity). I need to avoid jQuery if at all possible - at least including the full library. For example, given this block of HTML: <div> <p>This is a paragraph of text used as an example in this Stack Overflow question.</p> </div> and this array of strings to match: ['paragraph', 'example'] I would need to arrive at this: <div> <p>This is a <a href="http://www.example.com/">paragraph</a> of text used as an <a href="http://www.example.com/">example</a> in this Stack Overflow question.</p> </div> I've arrived at a solution to this by using the innerHTML() method and some string manipulation - basically using the offsets (via indexOf()) and lengths of the strings in the array to break the HTML string apart at the appropriate character offsets and insert <a href="http://www.example.com/"> and </a> tags where needed. However, an additional requirement has me stumped. I'm not allowed to wrap any matched strings in <a> elements if they're already in one, or if they're a descendant of a heading element (<h1> to <h6>). So, given the same array of strings above and this block of HTML (the term matching has to be case-insensitive, by the way): <div> <h1>Example</a> <p>This is a <a href="http://www.example.com/">paragraph of text</a> used as an example in this Stack Overflow question.</p> </div> I would need to disregard both the occurrence of "Example" in the <h1> element, and the "paragraph" in <a href="http://www.example.com/">paragraph of text</a>. This suggests to me that I have to determine which node each matched string is in, and then traverse its ancestors until I hit <body>, checking to see if I encounter a <a> or <h_> node along the way. Firstly, does this sound reasonable? Is there a simpler or more obvious approach that I've failed to consider? It doesn't seem like regular expressions or another string-based comparison to find bounding tags would be robust - I'm thinking of issues like self-closing elements, irregularly nested tags, etc. There's also this... Secondly, is this possible, and if so, how would I approach it?

  • Why isn't the static constructor of the parent class called when invoking a method on a nested class

    - by Ryan Ische
    Given the following code, why isn't the static constructor of "Outer" called after the first line of "Main"? namespace StaticTester { class Program { static void Main( string[] args ) { Outer.Inner.Go(); Console.WriteLine(); Outer.Go(); Console.ReadLine(); } } public static partial class Outer { static Outer() { Console.Write( "In Outer's static constructor\n" ); } public static void Go() { Console.Write( "Outer Go\n" ); } public static class Inner { static Inner() { Console.Write( "In Inner's static constructor\n" ); } public static void Go() { Console.Write( "Inner Go\n" ); } } } }

  • XML: When to use attributes instead of child nodes?

    - by Rosarch
    For tree leaves in XML, when is it better to use attributes, and when is it better to use descendant nodes? For example, in the following XML document: <?xml version="1.0" encoding="utf-8" ?> <savedGame> <links> <link rootTagName="zombies" packageName="zombie" /> <link rootTagName="ghosts" packageName="ghost" /> <link rootTagName="players" packageName="player" /> <link rootTagName="trees" packageName="tree" /> </links> <locations> <zombies> <zombie> <positionX>41</positionX> <positionY>100</positionY> </zombie> <zombie> <positionX>55</positionX> <positionY>56</positionY> </zombie> </zombies> <ghosts> <ghost> <positionX>11</positionX> <positionY>90</positionY> </ghost> </ghosts> </locations> </savedGame> The <link> tag has attributes, but it could also be written as: <link> <rootTagName>trees</rootTagName> <packageName>tree</packageName> </link> Similarly, the location tags could be written as: <zombie positionX="55" positionY="56" /> instead of: <zombie> <positionX>55</positionX> <positionY>56</positionY> </zombie> What reasons are there to prefer one over the other? Is it just a stylistic issue? Any performance considerations?

  • Hibernate cascading: should setting to null on a parent delete children?

    - by EugeneP
    I wonder if Hib works as expected in my case? My Cascading options are set to "all,delete-orphan". Table_A @OneToOne Table_B Table_B @OneToMany Table_C Now it looks like Table_A . getTable_B . getTable_C_Collection() Suppose there are elements in Table_C collection. What I expect from Hibernate: if I set Table_B link to null, then all Table_C collection elements MUST BE DELETED. It does not happen. They become ORPHANED !

  • How can I concatinate a subquery result field into the parent query?

    - by Pure.Krome
    Hi folks, DB: Sql Server 2008. I have a really (fake) groovy query like this:- SELECT CarId, NumberPlate (SELECT Owner FROM Owners b WHERE b.CarId = a.CarId) AS Owners FROM Cars a ORDER BY NumberPlate And this is what I'm trying to get... => 1 ABC123 John, Jill, Jane => 2 XYZ123 Fred => 3 SOHOT Jon Skeet, ScottGu So, i tried using AS [Text()] ... FOR XML PATH('') but that was inlcuding weird encoded characters (eg. carriage return). ... so i'm not 100% happy with that. I also tried to see if there's a COALESCE solution, but all my attempts failed. So - any suggestions?

  • How can I enable child inputs text selection in Mozilla Firefox using CSS?

    - by L. Shaydariv
    Hi. Let consider the following scenario. I have the following page where all rendered elements must be non-selectable. <html> <head> <style type="text/css"> body { -webkit-user-select: none; -moz-user-select: none; } div { border: solid 1px green; padding: 5px; } </style> </head> <body> <div> Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim ad minim veniam, quis nostrud exerci tation ullamcorper suscipit lobortis nisl ut aliquip ex ea commodo consequat. Duis autem vel eum iriure dolor in hendrerit in vulputate velit esse molestie consequat </div> <div> <input type="text" value="You can select the text from me" /> <textarea> And me too. </textarea> </div> </body> </html> The input and textarea text is still selectable in Google Chrome, but the text is not selectable in Firefox. I've already tried the following: input, textarea { -moz-user-select: text !important; } And... It simply doesn't work because (as far as I can see) input and textarea are nested in the document body element that's already is not selectable. So, is it possible to enable text selection of the nested user input elements in Firefox using CSS? Thank you for suggestions.

  • Can I make a matrix row group span its child groups in SSRS?

    - by AaronSieb
    I have a matrix, whose rows are grouped into two groups. A class, and a time for that class. The class cell is going to end up being several lines long, and I'd like the rows for each time slot of the class to line up next to the class description, like this: ----------------------------------------- **Class** | 7:00am | [row data] Description of |---------------------- the class, this | 12:00pm | [row data] is several lines |---------------------- long. | 1:00pm | [row data] ----------------------------------------- But what I'm getting is this: ----------------------------------------- **Class** | 7:00am | [row data] Description of | | the class, this | | is several lines | | long. | | ----------------------------------------- | 12:00pm | [row data] | | | | | | | | ----------------------------------------- | 1:00pm | [row data] | | | | | | | | ----------------------------------------- Is there any way to make SSRS collapse the matrix?

  • What is the best practise to create MSI with some other child MSI as prerequisite?

    - by sankar
    Currently we are using Innosetup as a bootstrapper to install the MSI prerequisites. It makes bit complex to maintain the setup. I found that burn tool which may help us to resolve this issue by having a single setup to install whatever we need. I could not find either documentation or sample for this tool. Is anyone have idea about this? or you can give me the alternate solution if you have. Looking for the alternate soltuion for the actions that we do with ISS bootstrapper now: Extract the files (Main setup, Prerequisite setup) Need to ensure prerequisites status and install on demand. Start main install.

  • Is there any way to manipulate variables passed in to a child class constructor before passing it of

    - by Matt
    Hi, Is there any way to delay calling a superclass constructor so you can manipulate the variables first? Eg. public class ParentClass { private int someVar; public ParentClass(int someVar) { this.someVar = someVar; } } public class ChildClass : ParentClass { public ChildClass(int someVar) : base(someVar) { someVar = someVar + 1 } } I want to be able to send the new value for someVar (someVar + 1) to the base class constructor rather than the one passed in to the ChildClass constructor. Is there any way to do this? Thanks, Matt

  • ASP.NET- forcing child/container events to fire before parent onload?

    - by Hans Gruber
    I'm working on a questionnaire type application in which questions are stored in a database. Therefore, I create my controls dynamically on every Page.OnLoad. This works like a charm and ViewState is persisted between postbacks because I ensure that my dynamic controls always have the same generated Control.ID. In addition to the user control that dynamically populates the questions, my questionnaire page also contains a 'Status' section (also encapsulated by a user control) which represents the status of the questionnaire (choices are 'Complete', 'Started' or 'In Progress'). If the user changes the status of questionnaire (i.e. from 'In Progress' to 'Complete'), I need to postback to the server because the contents of the dynamic portion of the questionnaire depend on the selected status. Some questions are always present regardless of status, and yet others may not be present at all for the selected status. The point is, when the status changes, I have to postback to the page and render the right set of questions. Additionally, I need to preserve any user entered values for those questions which are 'always available'. However, due to the page life cycle in ASP.NET, the 'Status' user control's OnLoad, which contains the correct status needed to load the right questions from the DB, doesn't get executed until after the 'dynamic questions' user control has already been populated (with the wrong/stale values). To get around this, I raise an event from my 'Status' user control to the main page to indicate that the Status has changed. The main page then raises an event on the 'dynamic questions' user control. Since by the time this event bubbles up, the 'dynamic questions' user control has already loaded the 'wrong' questions from the DB, it first calls Controls.Clear. It then happily uses the new status to query the database for the 'correct' questions and does a Control.Add() on each. FYI, Control.IDs are consistent across postbacks. This solution works...sorta. The correct set of questions for the selected status do get rendered; however ViewState is getting lost for those 'always available' questions. I'm guessing this is because the 'dynamic questions' user control calls Controls.Clear when responding to the status changed event. This must somehow kill the association between ViewState and my dynamic controls, even though the Control.ID are consistent. This seems like such a common requirement, I'm virtually certain there is a better, cleaner and less error prone approach to accomplish this. In case its not plain obvious, I haven't been able to grok the ASP.NET page life-cycle despite working with it for the last year. Any help is much appreciated!

  • mod_rewrite if file exists

    - by Mathieu Parent
    Hi everyone, I already have two rewrite rules that work correctly for now but some more code has to be added to work perfectly. I have a website hosted at mydomain.com and all subdom.mydomain.com are rewrited to mydomain.com/subs/subdom . My CMS has to handle the request if the file being reached does not exist, the rewrite is done like so: RewriteCond $1 !^subs/ RewriteCond %{HTTP_HOST} ^([^.]+)\.mydomain\.com$ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ subs/%1/index.php?page=$1 [L] My CMS handles the next part of the parsing as usual. The problem is if a file really exists, I need to link to it without passing through my CMS, I managed to do it like this: RewriteCond $1 !^subs/ RewriteCond %{HTTP_HOST} ^([^.]+)\.mydomain\.com$ RewriteCond %{REQUEST_FILENAME} -f [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^(.*)$ subs/%1/$1 [L] So far it seems to work like a charm. Now I am being picky and I need to have default files that are stored in subs/default/. If the file exists in the subdomain folder, we should grab this one but if not, we need to get the file from the default subdomain. And if the file does not exist anywhere, we should be using the 404 page from the current subdomain unless there is none. I hope it describes well enough. Thank you for your time!

  • css: make background repeat-y with growing child content?

    - by mikemikemike
    I Have a three column layout. The center div is a container which holds all of my content. The outer columns is just a .png that fades into the body's background (left and right respectively). I want the .png to repeat-y to grow with the center container's content. It will only print the image once, and ignores the repeat-y. If I specify a height to the outside columns, it will print, but only to the specified height. I tried height: 100%, which does not work. Here is my code: #ultra_contain { text-align:left; width:900px; padding: 0px; position:relative; margin:0px auto; margin-top:0px; /*border:1px dashed #996;*/ } #gradientleft { float:left; position:relative; background: url("../i/gradient_left.png") repeat-y; /*border:1px dashed #996;*/ } #gradientright { float:right; position:relative; background: url("../i/gradient_right.png") repeat-y; /*border:1px dashed #996;*/ } #container { text-align:left; width:700px; position:relative; margin:5px auto; margin-top:0px; background:#fff; /*border:1px dashed #996;*/ }
