  • Is there an easy way to compare if 2 XDocuments are equal ignoring element/attribute order?

    - by Davy8
    Unit testing my serialization code I found one failed because I had attributes listed in a different order (I'm just comparing the XDocument.ToString() values) and while I could fix that, it really doesn't matter to me in what order the elements or attributes appear as long as they're all there with the right name at the right level of hierarchy. I could probably write a method do this, but I'm wondering if there's an easy built in way I'm not aware of.

  • What is the most efficiant way to get the highest and the lowest value in a Array

    - by meo
    is there something like PHP: max() in javascript? lets say i have an array like this: [2, 3, 23, 2, 2345, 4, 86, 8, 231, 75] and i want to return the highest and the lowest value in this array. What is the fastest way to do that? i have tried: function madmax (arr) { var max = arr[0], min = arr[1] if (min > max) { max = arr[1] min = arr[0] } for (i=1;i<=arr.length;i++){ if( arr[i] > max ) { max = arr[i] }else if( arr[i] < min ) { min = arr[i] } } return max, min } madmax([123, 2, 345, 153, 5, 98, 456, 4323456, 1, 234, 19874, 238, 4]) Is there a simpler way retrieve the max and min value of a array?

  • Will JavaScript evaluate a property's value if it's not part of an assignment statement?

    - by Bungle
    I've come across a fairly obscure problem having to do with measuring a document's height before the styling has been applied by the browser. More information here: http://sonspring.com/journal/jquery-iframe-sizing http://ajaxian.com/archives/safari-3-onload-firing-and-bad-timing In Dave Hyatt's comment from June 27, he advises simply checking the document.body.offsetLeft property to force Safari to do a reflow. Can I simply use the following statement: document.body.offsetLeft; or do I need to assign it to a variable, e.g.: var force_layout = document.body.offsetLeft; in order for browsers to calculate that value? I think this comes down to a more fundamental question - that is, without being part of an assignment statement, will JavaScript still evaluate a property's value? Does this depend on whether a particular browser's JavaScript engine optimizes the code?

  • Can I use the auto-generated Linq-to-SQL entity classes in 'disconnected' mode?

    - by Gary McGill
    Suppose I have an automatically-generated Employee class based on the Employees table in my database. Now suppose that I want to pass employee data to a ShowAges method that will print out name & age for a list of employees. I'll retrieve the data for a given set of employees via a linq query, which will return me a set of Employee instances. I can then pass the Employee instances to the ShowAges method, which can access the Name & Age fields to get the data it needs. However, because my Employees table has relationships with various other tables in my database, my Employee class also has a Department field, a Manager field, etc. that provide access to related records in those other tables. If the ShowAges method were to invoke any of those methods, this would cause lots more data to be fetched from the database, on-demand. I want to be sure that the ShowAges method only uses the data I have already fetched for it, but I really don't want to have to go to the trouble of defining a new class which replicates the Employee class but has fewer methods. (In my real-world scenario, the class would have to be considerably more complex than the Employee class described here; it would have several 'joined' classes that do need to be populated, and others that don't). Is there a way to 'switch off' or 'disconnect' the Employees instances so that an attempt to access any property or related object that's not already populated will raise an exception? If not, then I assume that since this must be a common requirement, there might be an already-established pattern for doing this sort of thing?

  • How do I place another attribute to a MKAnnotation?

    - by kevin Mendoza
    for my app each annotation on a map corresponds to a mine locality. each mine has its own unique 7 digit integer identifier. I'm trying to add the property minesEntryNumber to the annotation so when the annotation is clicked on later I can bring up specific information on the selected annotation. This is part of my code: for (id mine in mines) { //NSLog(@"in the loop"); workingCoordinate.latitude = [[mine latitudeInitial] doubleValue]; workingCoordinate.longitude = [[mine longitudeInitial] doubleValue]; iProspectAnnotation *tempMine = [[iProspectAnnotation alloc] initWithCoordinate:workingCoordinate]; [tempMine setTitle:[mine mineName]]; tempMine.minesEntryNumber = [mine entryNumber]; //other code for dealing with mine types and adding the annotation to the mapview } the code works fine without the "tempMine.minesEntryNumber = [mine entryNumber];" part. It loads the map and shows the annotations. however when I try and put this in it brings up an error. So how do I add this property to each annotation and how do I access it later in a different .m file?

  • Is there an "extended" UIHint attribute to apply CSS styles for DisplayFor - EditorFor templates?

    - by AJ
    Intro: After reading Brad Wilson Metadata series and searching unsuccesfully on google, I was wondering: Question: Has any OS project / code been created that allows you to tag CSS styles in the Meta information, for example in my (buddy) Model, I want to be able to decorate a property with multiple CSS styles (a single style you can fake with UIHint, I want to set many possible styles - and be able to "cross-utilise") eg. public class MyModel { [DisplayCssHint("h5")] [DisplayCssHint("color:#777;")] [EditorCssHint(".myCoolTextClass")] [EditorCssHint(".myOtherCoolTextClass")] public string Title{ get;set; } [DisplayCssHint(".normaltext")] [EditorCssHint(".myCoolTextClass")] [EditorCssHint(".myOtherCoolTextClass")] public string Message {get;set;} } Thoughts: I know that this does not seem like a logical place to put styling information, however as it is metadata and is discriptive... besides it would be nice to do this while prototyping - (especially being able to apply class styles and extending it further - to generate .Less files would really be cool! more to the point I would hate to write it, if its already been done ;). Any links/pointers/idea's would be appreciated. Thanks,

  • How to convert an ASCII HEX character to it's value (0-15)?

    - by philcolbourn
    I am writing a string parser and the thought occurred to me that there might be some really interesting ways to convert an ASCII hexadecimal character [0-9A-Fa-f] to it's numeric value. What are the quickest, shortest, most elegant or most obscure ways to convert [0-9A-Fa-f] to it's value between 0 and 15? Assume, if you like, that the character is a valid hex character. I have no chance so I'll have a go at the most boring. ( c <= '9' ) ? ( c - '0' ) : ( (c | '\x60') - 'a' + 10 )

  • Html.DropDownListFor() in Mozilla Firefox

    - by Andrey
    I'm rendering a drop down list using Html.DropDownListFor() extension. The markup I get is as follows: select id="NationalityId" name="NationalityId" option value="" /option option selected="selected" value="1"Estonian /option option value="2"Russian /option option value="3"Ukranian /option option value="4"Belorussian /option option value="5"Swedish /option option value="6"Dutch /option /select As you can see, option with value==1 is selected. But in Firefox 3.6.3 it doesn't display as selected, empty string (first option - value == "") is displayed instead. IE7 and Chrome render the page right - the option is selected. Does anybody know what is going on? How do I get this around?

  • Why does a checkbox's "checked" attribute return the opposite of it's actual value on click event?

    - by Kappers
    I've got the following HTML <li><input type="checkbox" /><label>This is the label!</label></li> I bound a click event to the li, and let the click event bubble up to the li before doing anything else. $('li').each(function(i){ var item = $(this); var checkbox = $("input[type='checkbox']", item); item.bind('click', function(e){ var isChecked = checkbox.is(':checked'); console.log(isChecked); e.stopPropagation(); }); }); Starting with an unchecked checkbox, when the click event fires, isChecked returns true when I click on the checkbox, but returns false when I click on the label or li. Does anyone know why?

  • Grouping with operands question

    - by Filip
    I have a table: mysql> desc kursy_bid; +-----------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-----------+-------------+------+-----+---------+-------+ | datetime | datetime | NO | PRI | NULL | | | currency | varchar(6) | NO | PRI | NULL | | | value | varchar(10) | YES | | NULL | | +-----------+-------------+------+-----+---------+-------+ 3 rows in set (0.01 sec) I would like to select some rows from a table, grouped by some time interval (can be one day) where I will have the first row and the last row of the group, the max(value) and min(value). I tried: select datetime, (select value order by datetime asc limit 1) open, (select value order by datetime desc limit 1) close, max(value), min(value) from kursy_bid_test where datetime > '2009-09-14 00:00:00' and currency = 'eurpln' group by month(datetime), day(datetime), hour(datetime); but the output is: | open | close | datetime | max(value) | min(value) | +--------+--------+---------------------+------------+------------+ | 1.4581 | 1.4581 | 2009-09-14 00:00:05 | 4.1712 | 1.4581 | | 1.4581 | 1.4581 | 2009-09-14 01:00:01 | 1.4581 | 1.4581 | As you see open and close is the same (but they shouldn't be). What should be the query to do what I want?

  • How to make a link open in tabbed or new window without target attribute?

    - by Alan McCloud
    In my application an external website places link in my web page and the link does not have target=_blank. More specifically its iframe in my webpage whose src is another domain which I have no control. The content in this iframe contains links that opens in the same window wiping off my ajax driven web page and taking the user to the other domain. Is there a way to intercept this ( via javascript? ) and make the link open in another window or browser tab? It would be even much better if the link opens within the same iframe on my webpage. Is this possible? Is target="_self" makes the link open in the same iframe?

  • Best practice. Do I save html tags in DB or store the html entity value?

    - by Matt
    Hi Guys, I was wondering about which way i should do the following. I am using the tiny MCE wysiwyg editor which formats the users data with the right html tags. Now, i need to save this data entered into the editor into a database table. Should I encode the html tags to their corresponding entities when inserting into the DB, then when i get the data back from the table, not have the encode it for XSS purposes but I'd still have to use eval for the html tags to format the text. OR Do i save the html tags into the database, then when i get the data back from the database encode the html tags to their entities, but then as the tags will appear to the user, I'd have to use the eval function to actually format the data as it was entered. My thoughts are with the first option, I just wondered on what you guys thought.

  • can I auto update my uitextview from the value of the row of my uipickerview without pressing any se

    - by Wesley
    So I have a uipicker view, that I have managed to load some data from my db into. I would like to update a textview, which is right above the pickerview, with each changing of the row. Is that possible? If I don't have to, I would like to avoid pushing a button in order to show the respective text. Can I make it so that the value in the text field changes with the value of the rowselected in the pickerview, in real time? Any thoughts or code snippets would be appreciated. Thanks!

  • CQRS - Should a Command try to create a "complex" master-detail entity?

    - by Simon Crabtree
    I've been reading Greg Young and Udi Dahan's thoughts on Command Query Responsibilty Separation and a lot of what I read strikes a chord with me. My domain (we track vehicles which are doing deliveries) has the concept of a Route which contains one or more Stops. I need my customers to be able to set these up in our system by calling a webservice, and then be able to retrieve information about a Route and how the vehicle is progressing. In the past I would have "cut-down" DTO classes which closely resemble my domain classes, and the customer would create a RouteDto with an array of StopDto(s), and call our CreateRoute webmethod, passing in the RouteDto. When they query our system by calling the GetRouteDetails method, I would return exactly the same objects to them. One of the appealing aspects of CQRS is that the RouteDto might have all manner of properties that the customer wants to query, but have no business setting when they create a Route. So I create a separate CreateRouteRequest class which is passed in when calling the CreateRoute "command", and a Route DTO class which gets returned as a query result. class Route{ string Reference; List<Stop> Stops; } But I need my customer to provide me with Route AND Stop details when they create a route. As I see it I could either... Give my CreateRouteRequest class a Stops(s) property which is an array of "something" representing the data they need to provide about each stop - but what do I call this class? It's not a Stop as that's what I'm calling the list of DTO inside my Route DTO, but I don't like "CreateStopRequest". I also wonder if I'm stuck in a CRUD mindset here thinking in terms of master-detail information and asking the customer to think like that too. class CreateRouteRequest{ string Reference; ... List<CreateStopRequest> Stops; } or They call CreateRoute, and then make a number of calls to an AddStopToRoute method. This feels a bit more "behavioural" but I'm going to lose the ability to treat creating a route including its stops as a single atomic command. If they create a Route and then try to add a Stop which fails due to some validation problem they're going to have a partially correct Route. The fact that I can't come up with a good name for the list of "StopCreationData" objects I'd be working with in option 1, makes me wonder if there's something I'm missing.

Thanks for the help and support.

  • If I specify a System property multiple times when invoking JVM which value is used?

    - by RobV
    If I specify a system property multiple times when invoking the JVM which value will I actually get when I retrieve the property? e.g. java -Dprop=A -Dprop=B -jar my.jar What will be the result when I call System.getProperty("prop");? The Java documentation on this does not really tell me anything useful on this front. In my non-scientific testing on a couple of machines running different JVMs it seems like the last value is the one returned (which is actually the behavior I need) but I wondered if this behavior is actually defined officially anywhere or can it vary between JVMs?

  • Does Displaytag stash the "media type" in a page or request attribute?

    - by Pointy
    When you enable "export" from Displaytag, the tag code gives you links with special magic parameters that the tag recognizes as indicators that the table contents should be exported (as CSV, Excel, whatever). Well I'm interested in detecting the media type so that (for example) I can exclude columns that make no sense in an export (embedded action buttons, for one thing, or checkboxes for row selection). I suppose I could write a table decorator and use that to stick the media type on the request, but it'd be nice to avoid that if the tag already does it. The documentation is not clear on the subject; I guess I can start digging through the source code too.
