  • JQuery - is at least one checkbox checked

    - by Laramie
    I am in the process of learning JQuery thanks mostly to the positive reference here on Stack Overflow. I need a function that checks all the checkboxes in an element which have the same CSS class. It should returns true if at least one of them is checked. There are also other boxes in the element that are irrelevant to the check. The CSS class is unnecessary and only in place to create a way to identify the checkboxes in the group. It feels like bad practice, so any recommendations about other ways to identify them are welcome.

  • Passing a 'var' into another method

    - by Danny
    Hi, I am probably totally missing the point here but.... How can I pass a 'var' into another method? (I am using linq to load XML into an Enumerable list of objects). I have differernt object types (with different fields), but the final step of my process is the same regardless of which object is being used. XNamespace xmlns = ScehmaName; var result = from e in XElement.Load(XMLDocumentLocation).Elements(xmlns + ElementName) select new Object1 { Field1 = (string)e.Element(xmlns + "field1"), Field2 = (string)e.Element(xmlns + "field2") }; var result2 = Enumerable.Distinct(result); This code will vary for the different type of XML files that will be processed. But I then want to iterate though the code to check for various issues: foreach (var w in result2) { if (w.CheckIT()) { //do something } } What I would love is the final step to be in a method in the base class, and I can pass the 'var' varible into it from each child class.

  • Which data structure for List of objects + datagrid wiev

    - by Martin
    Hi, I have to develop a code which will store a list of objects, as example below 101, value 11, value 12, value 13 ...etc 102, value 21, value 22, value 23 ...etc 103, value 31, value 32, value 33 ...etc 104, value 41, value 42, value 43 ...etc Now, the difficulty is, that first column is an identifier, and whole table should always be sorted by it. Easy access to each element is required. Additionally, list should be easily updated, and extended by adding element at the end as well as in front and still keep being sorted by first column. Finally, I would like to be able to display values of the above in datagridview. What is most important is a performance of the implementation, as rows will be updated many times per second, and datagridview should be able to display all changes immediately. I was thinking about creating class for the values, and then a Dictionary but encountered a problem with displaying values in gridview. What would be the most optimal way of implementing the code? Thanks in advance Martin

  • Remove binding to FrameworkElementFactory

    - by Damien
    I am currently creating a datatemplate to display data in a listview control in a specific manner and bound to the data. This works fine. But I need to be able to remove the bindings when the screen is closed and control is being disposed. How can I do this? I am thinking of just passing null as the second parameter of SetBinding and not sure if this will fix the issue. Also I have tried BindingOperation.ClearBindings, but I have a FrameworkElementFactory object and not a DependancyObject. Any help would be appricaited. //Create a Element Factory object to save the elements that make //up the DataTemplate cellTemplateFactory = new FrameworkElementFactory(typeof(TextBlock)); //Set the binding to the text property of the textblock element var binding = new Binding(dispColumn.BindingField) { TargetNullValue = string.Empty, Mode = BindingMode.OneTime };

  • Algorithm to find a measurement of similarity between lists.

    - by Cubed
    Given that I have two lists that each contain a separate subset of a common superset, is there an algorithm to give me a similarity measurement? Example: A = { John, Mary, Kate, Peter } and B = { Peter, James, Mary, Kate } How similar are these two lists? Note that I do not know all elements of the common superset. Update: I was unclear and I have probably used the word 'set' in a sloppy fashion. My apologies. Clarification: Order is of importance. If identical elements occupy the same position in the list, we have the highest similarity for that element. The similarity decreased the farther apart the identical elements are. The similarity is even lower if the element only exists in one of the lists. I could even add the extra dimension that lower indices are of greater value, so a a[1] == b[1] is worth more than a[9] == b[9], but that is mainly cause I am curious.

  • XML testing in Rails - Fixed attributes order in Builder::XmlMarkup in ruby -

    - by Daniel Cukier
    I have the following test in my Rails Application: it "should validate xml" do builder = Builder::XmlMarkup.new builder.server(:name => "myServer", :ip => "192.168.1.1").should == "<server name=\"myServer\" ip=\"192.168.1.1\"/>" end The problem is that this test passes sometimes, because the order of the xml tag attributes is unpredictable. Is there a way to force this order? Is there any other easy way to build xml? This example is simplified, I have a big XML. My problem is that I want to do an integration test, which compares a WebService call with a fixed XML file. Otherwise, I would have to parse the xml and verify element by element in the XML.

  • filtering elements from list of lists in Python?

    - by user248237
    I want to filter elements from a list of lists, and iterate over the elements of each element using a lambda. For example, given the list: a = [[1,2,3],[4,5,6]] suppose that I want to keep only elements where the sum of the list is greater than N. I tried writing: filter(lambda x, y, z: x + y + z >= N, a) but I get the error: <lambda>() takes exactly 3 arguments (1 given) How can I iterate while assigning values of each element to x, y, and z? Something like zip, but for arbitrarily long lists. thanks, p.s. I know I can write this using: filter(lambda x: sum(x)..., a) but that's not the point, imagine that these were not numbers but arbitrary elements and I wanted to assign their values to variable names.

  • I can't use dashes in XPATH on iphone using libxml2

    - by user249488
    I'm trying to parse HTML data using KissXML for iphone. I've noticed that I can't have dashes in the id() tag, otherwise it won't evaluate. For example, if I'm trying to get the element at I would do id("foo") However, if I try to get at element , and I try id("foo-bar") the libxml2 XPATH engine doesn't seem to return anything. It works using the XPATH check for firefox, though. Anyone run into this issue and know of a reason why it's happening or have a workaround (besides using the absolute XPATH path?)

  • An analog of String.Join(string, string[]) for IEnumerable<T>

    - by abatishchev
    class String contains very useful method - String.Join(string, string[]). It creates a string from an array, separating each element of array with a symbol given. But general - it doesn't add a separator after the last element! I uses it for ASP.NET coding for separating with "<br />" or Environment.NewLine. So I want to add an empty row after each row in asp:Table. What method of IEnumerable<TableRow> can I use for the same functionality?

  • Removing Redundant Data from a List<T>

    - by Mark
    I have a List of objects which are ordered. I would like to remove redundant objects where redundant does not necessarily mean duplicate. Here is an example: List<Point> points = new List<Point> { new Point(0, 10), new Point(1, 12), new Point(2, 16), new Point(3, 16), new Point(4, 16), new Point(5, 13), new Point(6, 16), }; I am interested in removing the new Point(3, 16) entry because it doesn't provide useful information; I already know that the element at 2=16 and the element at 4=16. The information that 3=16 doesn't do me any good in my application (because I already have the bounds {2,4}=16), so I would like to remove that entry. I'd also like to not that I want to keep the 5th and 6th entry because there are not consecutive entries where Y=16. Is there a slick way to do this with linq?

  • How to add values to a JSON object?

    - by Damiano
    Hello everybody, I have created an array with: var msg = new Array(); then, I have a function that add values to this array, this function is: function add(time, user, text){ var message = [time, user, text]; if (msg.length >= 50) msg.shift(); msg.push(message); } As you can see, if the array has 50 or more elements I remove the first with .shift(). Then I add an array as element. Ok, the code works perfectly, but now I have to loop the msg array to create a JSON obj. The JSON object should has this format: var obj = [ {'time' : time, 'user' : user, 'text' : text}, {'time' : time, 'user' : user, 'text' : text}, {'time' : time, 'user' : user, 'text' : text} ] I mean...i have to loop msg array and then store all the values inside the JSON object. I do not know how to "concatenate" the element of the array inside json obj. Could you help me? Thank you very much in advance!

  • ASP.NET Controls Not Recognized

    - by Liam
    I just installed the release version of Visual Studio 2010, and it looks like there's something wrong with the standard ASP.NET server controls. When I create a basic server control, such as a TextBox, the editor underlines it in green and says (I also get no intellisense for ASP.NET controls): Element 'TextBox' is not a known element. This can occur if there is a compilation error in the Web site, or the Web.config file is missing. The web site builds fine, and the Web.config file is not missing: <?xml version="1.0"?> <configuration> <system.web> <compilation debug="false" targetFramework="4.0" /> </system.web> </configuration> The controls work just fine in the code-behind, and they function correctly when I run the site. Is there some configuration problem here?

  • How can CSS stop Google Maps loading?

    - by AP257
    I have a page with a Google Maps div: <div id="map_canvas" style="width: 100%; height: 332px;" ></div> If I comment out my CSS, the map loads fine: if I include the CSS, the map controls load, but the map tiles don't load: there's just a grey background. This is the case even if I put the map div just after the <body> tag, not within any styled element at all. No CSS, it loads fine. With CSS, no map. Does anyone know what could be causing this? I don't quite understand what the problem can be if no CSS styles are being applied to any element that contains the map. If more diagnostics are needed, please let me know, and I'll deploy the broken map onto a staging site, so people can look at the source.

  • Java xsd validation of xml without namespace

    - by Darkflare
    Hi, I want to validate an xml file against an xsd schema. The xml files root element does not have any namespace or xsi details. It has no attributes so just . I have tried the following code from http://www.ibm.com/developerworks/xml/library/x-javaxmlvalidapi.html with no luck as I receive cvc-elt.1: Cannot find the declaration of element 'root' SchemaFactory factory = SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema"); File schemaFile = new File("schema.xsd"); Schema xsdScheme = factory.newSchema(schemaFile); Validator validator = xsdScheme.newValidator(); Source source = new StreamSource(xmlfile); validator.validate(source); The xml validates fine with the namespace headers included etc (added via xmlspy), but I would have thought the xml namespace could be declared without having to manually edit the source file?

  • Python: Find X to Y in a list of strings.

    - by TheLizardKing
    I have a list of maybe a 100 or so elements that is actually an email with each line as an element. The list is slightly variable because lines that have a \n in them are put in a separate element so I can't simply slice using fixed values. I essentially need a variable start and stop phrase (needs to be a partial search as well because one of my start phrases might actually be Total Cost: $13.43 so I would just use Total Cost:.) Same thing with the end phrase. I also do not wish to include the start/stop phrases in the returned list. In summary: email = ['apples','bananas','cats','dogs','elephants','fish','gee'] start = 'ban' stop = 'ele' the magic here new_email = ['cats','dogs'] NOTES While not perfect formatting of the email, it is fairly consistent so there is a slim chance a start/stop phrase will occur more than once. There are also no blank elements.
