  • I set up better-edit-in-place but still cannot edit in place in Rails

    - by Angela
    I installed the plugin better-edit-in-place (http://github.com/nakajima/better-edit-in-place) but I dont' seem to be able to make it work. When I use firebug, it is rendering the value to be edited correctly: <span rel="/emails/1" id="email_1_days" class="editable">7</span> And it is showing the full javascript which should work on class editable: var Editable = Class.create({ 5 initialize: function(element, options) { 6 this.element = $(element); 7 Object.extend(this, options); 8 9 // Set default values for options 10 this.editField = this.editField || {}; 11 this.editField.type = this.editField.type || 'input'; 12 this.onLoading = this.onLoading || Prototype.emptyFunction; 13 this.onComplete = this.onComplete || Prototype.emptyFunction; 14 15 this.field = this.parseField(); 16 this.value = this.element.innerHTML; 17 18 this.setupForm(); 19 this.setupBehaviors(); 20 }, 21 22 // In order to parse the field correctly, it's necessary that the element 23 // you want to edit in place for have an id of (model_name)_(id)_(field_name). 24 // For example, if you want to edit the "caption" field in a "Photo" model, 25 // your id should be something like "photo_#{@photo.id}_caption". 26 // If you want to edit the "comment_body" field in a "MemberBlogPost" model, 27 // it would be: "member_blog_post_#{@member_blog_post.id}_comment_body" 28 parseField: function() { 29 var matches = this.element.id.match(/(.*)_\d*_(.*)/); 30 this.modelName = matches[1]; 31 this.fieldName = matches[2]; 32 if (this.editField.foreignKey) this.fieldName += '_id'; 33 return this.modelName + '[' + this.fieldName + ']'; 34 }, But when I point my mouse at the element, no in-place-editing action!

  • Converting an integer to a boxed enum type only known at runtime

    - by Marc Gravell
    Imagine we have an enum: enum Foo { A=1,B=2,C=3 } If the type is known at compile-time, a direct cast can be used to change between the enum-type and the underlying type (usually int): static int GetValue() { return 2; } ... Foo foo = (Foo)GetValue(); // becomes Foo.B And boxing this gives a box of type Foo: object o1 = foo; Console.WriteLine(o1.GetType().Name); // writes Foo (and indeed, you can box as Foo and unbox as int, or box as int and unbox as Foo quite happily) However (the problem); if the enum type is only known at runtime things are... trickier. It is obviously trivial to box it as an int - but can I box it as Foo? (Ideally without using generics and MakeGenericMethod, which would be ugly). Convert.ChangeType throws an exception. ToString and Enum.Parse works, but is horribly inefficient. I could look at the defined values (Enum.GetValues or Type.GetFields), but that is very hard for [Flags], and even without would require getting back to the underlying-type first (which isn't as hard, thankfully). But; is there a more direct to get from a value of the correct underlying-type to a box of the enum-type, where the type is only known at runtime?

  • External API function calls AS3 control timeline

    - by giles
    I have function problem using this code (below), the embedded flash movieclip disappears or completely prevents the scrollto.js query to function in DW cs3. Communication between Flash and JavaScript is without problems, it is the call back I can't find to work and more frustratingly, should be simple, as no values are not required. So far, this has been hours of scouring the net without a workable end in sight...ahrr. What is a function for this to work? JavaScript – to call Flash event from HTML button link, placed between head tags function callExternalInterface() var flashMovie = window.document.menu; flashMovie.menu_up(value); menu_up is the string. Does anyone know of workable function for callback?? HTML <div id="btn_up"><a href="#top" name="charDev" id="charDev" onclick="">top</a></div> Pane navigation div that uses Scrollto.js query, and it's this link I need calling back to the embedded "menubtns.swf" (nested in "AS3Menu_javascript.swf") to play 5 frames of this movieclip, via a JS function. Embedded .swf code, using swfobject.js with allowScriptAccess=always <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" name="menu"<br/> width="251" height="251" id="menu"> <param name="movie" value="../~Assets/Flash/AS3Menu_javascript.swf" /> <param name="allowScriptAccess" value="always" /> <param name="movie" value="ExternalInterfaceScript.swf" /> <param name="quality" value="high" /> <object type="application/x-shockwave-flash" data="../~Assets/Flash/AS3Menu_javascript.swf" width="250" height="250"> <p>Alternative content</p> </object> </object> AS3 / Flash import flash.external.ExternalInterface;flash.system.Security.allowDomain(/sourceDomain/); ExternalInterface.addCallBack("menu_up", this, resetmenu); function resetmenu(){ gotoAndPlay:("frame label" / "number") }

  • JSF ISO-8859-2 charset

    - by Vladimir
    Hi! I have problem with setting proper charset on my jsf pages. I use MySql db with latin2 (ISO-8859-2 charset) and latin2_croatian_ci collation. But, I have problems with setting values on backing managed bean properties. Page directive on top of my page is: <%@ page language="java" pageEncoding="ISO-8859-2" contentType="text/html; charset=ISO-8859-2" %> In head I included: <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-2"> And my form tag is: <h:form id="entityDetails" acceptcharset="ISO-8859-2"> I've created and registered Filter in web.xml with following doFilter method implementation: public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { request.setCharacterEncoding("ISO-8859-2"); response.setCharacterEncoding("ISO-8859-2"); chain.doFilter(request, response); } But, i.e. when I set managed bean property through inputText, all special (unicode) characters are replaced with '?' character. I really don't have any other ideas how to set charset to pages to perform well. Any suggestions? Thanks in advance.

  • Perl Imager::Screenshot not doing screenshot with default parameters

    - by Grigor
    I have the following code: use Imager::Screenshot 'screenshot'; my $img = screenshot(hwnd => 'active', left => 450, right => 200, top => 50, bottom => 50); $img->write(file => 'screenshot.png', type => 'png' ) || print "Failed: ", $img->{ERRSTR} , "\n"; it returns: "Can't call method "write" on undefined value at line 3" but when I do: use Imager::Screenshot 'screenshot'; my $img = screenshot(hwnd => 'active', left => 100, right => 300, top => 100, bottom => 300); $img->write(file => 'screenshot.png', type => 'png' ) || print "Failed: ", $img->{ERRSTR} , "\n"; it does take a screenshot. Why would the left, right, top and bottom values matter here?

  • Doctrine2 ArrayCollection

    - by boosis
    Ok, I have a User entity as follows <?php class User { /** * @var integer * @Id * @Column(type="integer") * @GeneratedValue */ protected $id; /** * @var \Application\Entity\Url[] * @OneToMany(targetEntity="Url", mappedBy="user", cascade={"persist", "remove"}) */ protected $urls; public function __construct() { $this->urls = new \Doctrine\Common\Collections\ArrayCollection(); } public function addUrl($url) { // This is where I have a problem } } Now, what I want to do is check if the User has already the $url in the $urls ArrayCollection before persisting the $url. Now some of the examples I found says we should do something like if (!$this->getUrls()->contains($url)) { // add url } but this doesn't work as this compares the element values. As the $url doesn't have id value yet, this will always fail and $url will be dublicated. So I'd really appreciate if someone could explain how I can add an element to the ArrayCollection without persisting it and avoiding the duplication? Edit I have managed to achive this via $p = function ($key, $element) use ($url) { if ($element->getUrlHash() == $url->getUrlHash()) { return true; } else { return false; } }; But doesn't this still load all urls and then performs the check? I don't think this is efficient as there might be thousands of urls per user.

  • Reading CSV files in numpy where delimiter is ","

    - by monch1962
    Hello all, I've got a CSV file with a format that looks like this: "FieldName1", "FieldName2", "FieldName3", "FieldName4" "04/13/2010 14:45:07.008", "7.59484916392", "10", "6.552373" "04/13/2010 14:45:22.010", "6.55478493312", "9", "3.5378543" ... Note that there are double quote characters at the start and end of each line in the CSV file, and the "," string is used to delimit fields within each line. When I try to read this into numpy via: import numpy as np data = np.genfromtxt(csvfile, dtype=None, delimiter=',', names=True) all the data gets read in as string values, surrounded by double-quote characters. Not unreasonable, but not much use to me as I then have to go back and convert every column to its correct type When I use delimiter='","' instead, everything works as I'd like, except for the 1st and last fields. As the start of line and end of line characters are a single double-quote character, this isn't seen as a valid delimiter for the 1st and last fields, so they get read in as e.g. "04/13/2010 14:45:07.008 and 6.552373" - note the leading and trailing double-quote characters respectively. Because of these redundant characters, numpy assumes the 1st and last fields are both String types; I don't want that to be the case Is there a way of instructing numpy to read in files formatted in this fashion as I'd like, without having to go back and "fix" the structure of the numpy array after the initial read?

  • How do I create a multi-level TreeView using F#?

    - by TwentyMiles
    I would like to display a directory structure using Gtk# widgets through F#, but I'm having a hard time figuring out how to translate TreeViews into F#. Say I had a directory structure that looks like this: Directory1 SubDirectory1 SubDirectory2 SubSubDirectory1 SubDirectory3 Directory2 How would I show this tree structure with Gtk# widgets using F#? EDIT: gradbot's was the answer I was hoping for with a couple of exceptions. If you use ListStore, you loose the ability to expand levels, if you instead use : let musicListStore = new Gtk.TreeStore([|typeof<String>; typeof<String>|]) you get a layout with expandable levels. Doing this, however, breaks the calls to AppendValues so you have to add some clues for the compiler to figure out which overloaded method to use: musicListStore.AppendValues (iter, [|"Fannypack" ; "Nu Nu (Yeah Yeah) (double j and haze radio edit)"|]) Note that the columns are explicitly passed as an array. Finally, you can nest levels even further by using the ListIter returned by Append Values let iter = musicListStore.AppendValues ("Dance") let subiter = musicListStore.AppendValues (iter, [|"Fannypack" ; "Nu Nu (Yeah Yeah) (double j and haze radio edit)"|]) musicListStore.AppendValues (subiter, [|"Some Dude"; "Some Song"|]) |> ignore

  • iPhone contacts app styled indexed table view implementation

    - by KSH
    My Requirement: I have this straight forward requirement of listing names of people in alphabetical order in a Indexed table view with index titles being the starting letter of alphabets (additionally a search icon at the top and # to display misc values which start with a number and other special characters). What I have done so far: 1. I am using core data for storage and "last_name" is modelled as a String property in the Contacts entity 2.I am using a NSFetchedResultsController to display the sorted indexed table view. Issues accomplishing my requirement: 1. First up, I couldn't get the section index titles to be the first letter of alphabets. Dave's suggestion in the following post, helped me achieve the same: http://stackoverflow.com/questions/1112521/nsfetchedresultscontroller-with-sections-created-by-first-letter-of-a-string The only issue I encountered with Dave' suggestion is that I couldn't get the misc named grouped under "#" index. What I have tried: 1. I tried adding a custom compare method to NSString (category) to check how the comparison and section is made but that custom method doesn't get called when specified in the NSSortDescriptor selector. Here is some code: `@interface NSString (SortString) -(NSComparisonResult) customCompare: (NSString*) aStirng; @end @implementation NSString (SortString) -(NSComparisonResult) customCompare:(NSString *)aString { NSLog(@"Custom compare called to compare : %@ and %@",self,aString); return [self caseInsensitiveCompare:aString]; } @end` Code to fetch data: `NSArray *sortDescriptors = [NSArray arrayWithObject:[[[NSSortDescriptor alloc] initWithKey:@"last_name" ascending:YES selector:@selector(customCompare:)] autorelease]]; [fetchRequest setSortDescriptors:sortDescriptors]; fetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:@"lastNameInitial" cacheName:@"MyCache"];` Can you let me know what I am missing and how the requirement can be accomplished ?

  • Efficient alternative to merge() when building dataframe from json files with R?

    - by Bryan
    I have written the following code which works, but is painfully slow once I start executing it over thousands of records: require("RJSONIO") people_data <- data.frame(person_id=numeric(0)) json_data <- fromJSON(json_file) n_people <- length(json_data) for(lender in 1:n_people) { person_dataframe <- as.data.frame(t(unlist(json_data[[person]]))) people_data <- merge(people_data, person_dataframe, all=TRUE) } output_file <- paste("people_data",".csv") write.csv(people_data, file=output_file) I am attempting to build a unified data table from a series of json-formated files. The fromJSON() function reads in the data as lists of lists. Each element of the list is a person, which then contains a list of the attributes for that person. For example: [[1]] person_id name gender hair_color [[2]] person_id name location gender height [[...]] structure(list(person_id = "Amy123", name = "Amy", gender = "F", hair_color = "brown"), .Names = c("person_id", "name", "gender", "hair_color")) structure(list(person_id = "matt53", name = "Matt", location = structure(c(47231, "IN"), .Names = c("zip_code", "state")), gender = "M", height = 172), .Names = c("person_id", "name", "location", "gender", "height")) The end result of the code above is matrix where the columns are every person-attribute that appears in the structure above, and the rows are the relevant values for each person. As you can see though, some data is missing for some of the people, so I need to ensure those show up as NA and make sure things end up in the right columns. Further, location itself is a vector with two components: state and zip_code, meaning it needs to be flattened to location.state and location.zip_code before it can be merged with another person record; this is what I use unlist() for. I then keep the running master table in people_data. The above code works, but do you know of a more efficient way to accomplish what I'm trying to do? It appears the merge() is slowing this to a crawl... I have hundreds of files with hundreds of people in each file. Thanks! Bryan

  • Problem parsing an atom feed using simplexml_load_file(), can't get an attribute.

    - by Craig Ward
    Hi, I am trying to create a social timeline. I pull in feeds form certain places so I have a timeline of thing I have done. The problem I am having is with Google reader Shared Items.

  • Cannot Cache NHibernate Future Criteria Results

    - by Emilian
    I have the following code: public void FuturesQuery() { using (var session = SessionFactory.OpenSession()) { var blogs = session.CreateCriteria<Blog>() .SetMaxResults(5) .SetCacheable(true) .SetCacheMode(CacheMode.Normal) .SetCacheRegion("BlogQuery") .Future<Blog>(); var countOfBlogs = session.CreateCriteria<Blog>() .SetProjection(Projections.Count(Projections.Id())) .SetCacheable(true) .SetCacheMode(CacheMode.Normal) .SetCacheRegion("BlogQuery") .FutureValue<int>(); Console.WriteLine("Number of blogs: {0}", countOfBlogs.Value); foreach (var blog in blogs) { Console.WriteLine(blog.Title); } } using (var session = SessionFactory.OpenSession()) { var blogs = session.CreateCriteria<Blog>() .SetMaxResults(5) .SetCacheable(true) .SetCacheMode(CacheMode.Normal) .SetCacheRegion("BlogQuery") .Future<Blog>(); var countOfBlogs = session.CreateCriteria<Blog>() .SetProjection(Projections.Count(Projections.Id())) .SetCacheable(true) .SetCacheMode(CacheMode.Normal) .SetCacheRegion("BlogQuery") .FutureValue<int>(); Console.WriteLine("Number of blogs: {0}", countOfBlogs.Value); foreach (var blog in blogs) { Console.WriteLine(blog.Title); } } } I was expecting that the second time I query for blogs and count of blogs I will get values from cache but instead the queries hit the database. If I don't use Futures I get the expected results. Does this means that results from Criteria using futures cannot be cached?

  • ajax call to servlet puzzler

    - by vector
    Greetings! I'm having a problem getting a text value of a captcha from a servlet through ajax call. When my captcha gets created, its text value is written to session, but after refreshing the image itself though ajax call, I only get one old value of the text. Refreshing the image itself works ok, but I'm stuck getting the correct values from the session on subsequent call. On page reload I get both the new image and its new text value, no joy with ajax though. This works great for the image refresh: $("#asos").attr("src", "/ImageServlet?="+((new Date()).getTime()) ) This call to another method to get text value gives me old stuff: $.ajax({ url:"checkCaptcha", type:"GET", cache: false, success: function( data) { alert(data); } }); Any feedback will be appreciated. ps: here's the meat of the method getting the call: PrintWriter out = response.getWriter(); response.setContentType("text/html"); response.setDateHeader("Expires", 0 ); // Set standard HTTP/1.1 no-cache headers. response.setHeader("Cache-Control", "no-store, no-cache, must-revalidate"); // Set IE extended HTTP/1.1 no-cache headers (use addHeader). response.addHeader("Cache-Control", "post-check=0, pre-check=0"); // Set standard HTTP/1.0 no-cache header. response.setHeader("Pragma", "no-cache"); out.print( request.getSession( ).getAttribute("randomPixValue") ); out.close();

  • Multiselect Form Field in PDF

    - by Jason R. Coombs
    Using PDF, is it possible to create a single form element with multiple fields of which several can be selected? For example, in HTML, one can create a set of checkboxes associated with the same field name: <div>Select one for Member of the School Board</div> <input type="checkbox" name="field(school)" value="vote1"> <span class="label">Libby T. Garvey</span><br/> <input type="checkbox" name="field(school)" value="vote2"> <span class="label">Emma N. Violand-Sanchez</span><br/> In this case, the field name is "field(school)", and when the form is submitted, "field(school)" can be supplied 0, 1, or 2 times. Is there an equivalent construct in PDF where a single field can have multiple values. So far in my investigation, it appears that if fields are assigned the same name, it is only possible to select one field. If it is possible to implement this in PDF, what is this construct called and how can it be implemented? Edit: To clarify, I am aware that a PDF can contain multiple form fields with different field names, and those can be selected independently, but then the grouping is implicit and not explicit as with the HTML form. I would like to use a construct that makes the grouping of options explicit, and preferably allows for restrictions (e.g. at least one required, no more than 2 allowed, etc).

  • SSIS Lookup with Lookup Component Vs Script Component.

    - by Nev_Rahd
    Hello, I need to load Dimensions from EDW Tables (which does maintain historical records) and is of type Key-Value-Parameter. My scenario is ok if got a record in EDW as below Key1 Key2 Code Value EffectiveDate EndDate CurrentFlag 100 555 01 AAA 2010-01-01 11.00.00 9999-12-31 Y 100 555 02 BBB 2010-01-01 11.00.00 9999-12-31 Y This need to be loaded into DM by pivoting it as key1 and key2 combinations makes Natural key for DM SK NK 01 02 EffectiveDate EndDate CurrentFlag 1 100-555 AAA BBB 2010-01-01 11.00.00 9999-12-31 Y My ssis package does this all good pivoting... looking up the incoming NK in DIM.. if new will insert .. else with further lookup with effective date and determine if the incoming for same natural key got any new (change) in attribute.. if so updates the current record byy setting its end date and insert the new one with new attribute value and pulling the recent records values for other attributes. My problem is if the same natural key comes twice with same attribute in single extract my first lookup which on natural key .. will let both records pass and try to insert.. where its fails. If i get distinct records on NK the second is not picked and need to run package again. So my question how can i configure lookup or alernative way to handle this scenario when same NK comes twice in single extract, would be able to insert first record if not exists in Dim table and for second one should be able to updated with the changes with reference to one inserted above. Not sure this makes sense what am trying to explain. Will attached the screenshot once back to work desk (on monday). Thanks

  • An annoying printing issue with Crystal Reports 2008

    - by Xience
    A little background: I have an extremely annoying printing issue with crystal reports. My environment is crystal reports 2008 SP2 on Windows 7 (64bit), Visual studio 2008 and .net framework 3.5 with all the latest updates for everything. The report is designed basically to render a small shelf label of the size (40mm width and 20mm height). In crystal when I set the page size to the above mentioned values and set orientation to portrait and take a preview, everything is displayed as i expect it to be and issuing a print command, it prints absolutely correct. The problem: The problem comes when i print this report from my program (in vb.net), dynamically setting data to some text fields, the result is that crystal somehow changes the print orientation, NOT the paper orientation as in portrait or landscape. Instead of printing from top left towards the bottom right, it rotates the whole output at 90 degrees to the left and reduces everything so small that it is barely visible, although it prints everything out. I have tested it on Intermec PF8t and Zebra GK420d label printers and a whole bunch of laser printers, but with the above stated page settings the output is always the same. Another strange thing that i noticed while experimenting with page sizes if i switch to landscape mode, the print out is correct in its font sizes and positions but then the text gets truncated due to overflowing the page size. Can anyone help me with this. Does crystal has anything like its own print drivers or something. I have tried to ensure to the best of my abilities that it is not a printer driver problem.

  • WatiN NativeElement.GetElementBounds() - What is the unit of measurement?

    - by Brian Schroer
    When I'm testing with WatiN, I like to save screenshots. Sometimes I don't really need a picture of the whole browser window though - I just want a picture of the element that I'm testing. My attempt to save a picture of an element with the code below resulted in a picture of a block box, because elementBounds.Top points to a pixel position way past the bottom of the screen. The elementBounds.Width and .Height values also appear to be about half what they should be. Is this a WatiN bug, or are these properties in a different unit of measure that I have to convert to pixels somehow? public static void SaveElementScreenshot (WatiN.Core.IE ie, WatiN.Core.Element element, string screenshotPath) { ScrollIntoView(ie, element); ie.BringToFront(); var ieClass = (InternetExplorerClass) ie.InternetExplorer; Rectangle elementBounds = element.NativeElement.GetElementBounds(); int left = ieClass.Left + elementBounds.Left; int top = ieClass.Top + elementBounds.Top; int width = elementBounds.Width; int height = elementBounds.Height; using (var bitmap = new Bitmap(width, height)) { using (Graphics graphics = Graphics.FromImage(bitmap)) { graphics.CopyFromScreen (new Point(left, top), Point.Empty, new Size(width, height)); } bitmap.Save(screenshotPath, ImageFormat.Jpeg); } }

  • Safari Extension Questions

    - by Rob Wilkerson
    I'm in the process of building my first Safari extension--a very simple one--but I've run into a couple of problems. The extension boils down to a single, injected script that attempts to bypass the native feed handler and redirect to an http:// URI. My issues so far are twofold: The "whitelist" isn't working the way I'd expect. Since all feeds are shown under the "feed://" protocol, I've tried to capture that in the whitelist as "feed://*/*" (with nothing in the blacklist), but I end up in a request loop that I can't understand. If I set blacklist values of "http://*/*" and "https://*/*", everything works as expected. I can't figure out how to access my settings from my injected script. The script creates a beforeload event handler, but can't access my settings using the safari.extension.settings path indicated in the documentation. I haven't found anything in Apple's documentation to indicate that settings shouldn't be available from my script. Since extensions are such a new feature, even Google returns limited relevant results and most of those are from the official documentation. What am I missing? Thanks.

  • Weird switch behavior in .NET 4

    - by RaYell
    I have a problem understanding what's causes the compilation error in the code below: static class Program { static void Main() { dynamic x = ""; var test = foo(x); if (test == "test") { Console.WriteLine(test); } switch (test) { case "test": Console.WriteLine(test); break; } } private static string foo(object item) { return "bar"; } } The error I get is in switch (test) line: A switch expression or case label must be a bool, char, string, integral, enum, or corresponding nullable type. Intellisence shows me that foo operation will be resolved on runtime, which is fine because I'm using a dynamic type as a param. However I don't understand how if condition compiles fine when switch doesn't. Code above is just simplified version of what I have in my application (VSTO) which appeared after migrating the app from VSTO3 to VSTO4 when one method in VSTO was changed to return dynamic type values instead of object. Can anyone give me an explanation what's the problem. I know how to resolve it but I'd like to understand what's happening.

  • MVC Form and Dictionary Type

    - by Brian Schmitt
    I am attempting to use a property on my model that is of type Dictionary<string, string>. This dictionary is one of several other properties on the model, and I am using the dictionary as a key/value store to produce a 'dynamic' form. E.G.: User Name Settings A B I want to be able to submit and save any changes to settings A and B. I can submit the form and get my posted values in all my other fields, however the dictionary gets set to null. <%=Html.LabelFor(m => m.Name)%> <%=Html.DisplayFor(m => m.Name)%> <%=Html.LabelFor(m => m.Settings["A"])%> <%=Html.TextBoxFor(m => m.Settings["A"])%> <%=Html.LabelFor(m => m.Settings["B"])%> <%=Html.TextBoxFor(m => m.Settings["B"])%> Is there a better way to produce the dynamic form with a key/value pair? The actual code will be using partials (there several hundred variations), and the above is only a contrived example.

  • What is the Best way to databind an ASP.NET TreeView for table with many to many parent child relati

    - by Matt W
    I've got a table which has the usual ParentID, ChildID as it's first two columns in a self-referencing tree data structure. My issue is that when I pull this out and use the following code: DataSet set = DA.GetNewCategories(); set.Relations.Add( new DataRelation("parentChildCategories", set.Tables[0].Columns["CategoryParentID"], set.Tables[0].Columns["CategoryID"]) ); StringBuilder buildXml = new StringBuilder(); StringWriter writer = new StringWriter(buildXml); set.WriteXml(writer); TreeView2.DataSource = new HierarchicalDataSet(set, "CategoryID", "CategoryParentID"); TreeView2.DataBind(); I get the error: These columns don't currently have unique values I believe this is because my data has children with multiple parent nodes. This is fine for my application - I don't mind if one row of data is rendered in multiple nodes of my TreeView. Could someone shed light on this please? It doesn't seem unreasonable to have a DataSet render XML which has nodes appearing in multiple places, but I can't figure out how to do it. Thanks, Matt.

  • Idiomatic Scala way to deal with base vs derived class field names?

    - by Gregor Scheidt
    Consider the following base and derived classes in Scala: abstract class Base( val x : String ) final class Derived( x : String ) extends Base( "Base's " + x ) { override def toString = x } Here, the identifier 'x' of the Derived class parameter overrides the field of the Base class, so invoking toString like this: println( new Derived( "string" ).toString ) returns the Derived value and gives the result "string". So a reference to the 'x' parameter prompts the compiler to automatically generate a field on Derived, which is served up in the call to toString. This is very convenient usually, but leads to a replication of the field (I'm now storing the field on both Base and Derived), which may be undesirable. To avoid this replication, I can rename the Derived class parameter from 'x' to something else, like '_x': abstract class Base( val x : String ) final class Derived( _x : String ) extends Base( "Base's " + _x ) { override def toString = x } Now a call to toString returns "Base's string", which is what I want. Unfortunately, the code now looks somewhat ugly, and using named parameters to initialize the class also becomes less elegant: new Derived( _x = "string" ) There is also a risk of forgetting to give the derived classes' initialization parameters different names and inadvertently referring to the wrong field (undesirable since the Base class might actually hold a different value). Is there a better way? Edit: To clarify, I really only want the Base values; the Derived ones just seem necessary for initializing the Base ones. The example only references them to illustrate the ensuing issues. It might be nice to have a way to suppress automatic field generation if the derived class would otherwise end up hiding a base class field.

  • Video-codec rater by image comparison algorithm?

    - by Andreas Hornig
    Hi, perhaps anyone knows if this is possible. comparing image quality is almost imposible to describe without subjective influences. When someone rates an image quality as good there is at least one person, that doesn't think so. human preferences are always different. So, I would like to know if there is away to "rate" the image quality by an algorithm that compares the original image to the produced one in following issues colour change(difference pixel by pixel blur rate artifacts and macroblocking the first one would be the easiest one because you could check just the diffeence in colours and can give 3 values in +- of each hex-value both last once I don't know if this is possible, but the blocking could be detected by edge-finding. and the king's quest would be to do that for more then just one image, because video is done with several frames. perhaps you expert programmers could tell me, if such an automated algo can be done to bring some objective measurement divice into rating image quality. this could perhaps calm down some h.264 is better than x264 and better than vp8 and blaaah people :) Andreas 1st posted here http://www.hdtvtotal.com/index.php?name=PNphpBB2&file=viewtopic&p=9705

  • C# Setting Properties using Index

    - by Guazz
    I have a business class that contains many properties for various stock-exchange price types. This is a sample of the class: public class Prices { public decimal Today {get; set} public decimal OneDay {get; set} public decimal SixDay {get; set} public decimal TenDay {get; set} public decimal TwelveDay {get; set} public decimal OneDayAdjusted {get; set;} public decimal SixDayAdjusted {get; set;} public decimal TenDayAdjusted {get; set;} public decimal OneHundredDayAdjusted {get; set;} } I have a legacy system that supplies the prices using string ids to identify the price type. E.g. Today = "0D" OneDay = "1D" SixDay = "6D" //..., etc. Firstly, I load all the values to an IDictionary() collection so we have: [KEY] VALUE [0D] = 1.23456 [1D] = 1.23456 [6D] = 1.23456 ...., etc. Secondly, I set the properties of the Prices class using a method that takes the above collection as a parameter like so: SetPricesValues(IDictionary<string, decimal> pricesDictionary) { // TODAY'S PRICE string TODAY = "D0"; if (true == pricesDictionary.ContainsKey(TODAY)) { this.Today = pricesDictionary[TODAY]; } // OneDay PRICE string ONE_DAY = "D1"; if (true == pricesDictionary.ContainsKey(ONE_DAY)) { this.OneDay = pricesDictionary[ONE_DAY]; } //..., ..., etc., for each other property } Is there a more elegant technique to set a large amount of properties? Thanks, j
