  • How to normalize SVG path data (cross browser)?

    - by Timo
    I have tried to find a way to implement cross browser path normalizer. There IS a native way which is described here and functional example is here, but it works only in newest Opera (but not in IE, FF, Safari, Chrome). The native way uses pathElm.normalizedPathSegList and it converts all relative coordinates to absolute ones and represents all path segment types as a following subset of types: M,L,C,z. I have found only one javascript code and jsfiddled functional example of it, but it works only in IE and FF. Chrome gives "Uncaught Error: INDEX_SIZE_ERR: DOM Exception 1". How this could be fixed to work also in Opera, Safari and Chrome or is there any other way for normalizing SVG paths?

  • Cannot perform an ORDERBY against my EF4 data

    - by Jaxidian
    I have a query hitting EF4 using STEs and I'm having an issue with user-defined sorting. In debugging this, I have removed the dynamic sorting and am hard-coding it and I still have the issue. If I swap/uncomment the var results = xxx lines in GetMyBusinesses(), my results are not sorted any differently - they are always sorting it ascendingly. FYI, Name is a varchar(200) field in SQL 2008 on my Business table. private IQueryable<Business> GetMyBusinesses(MyDBContext CurrentContext) { var myBusinesses = from a in CurrentContext.A join f in CurrentContext.F on a.FID equals f.id join b in CurrentContext.Businesses on f.BID equals b.id where a.PersonID == 52 select b; var results = from r in myBusinesses orderby "Name" ascending select r; //var results = from r in results // orderby "Name" descending // select r; return results; } private PartialEntitiesList<Business> DoStuff() { var myBusinesses = GetMyBusinesses(); var myBusinessesCount = GetMyBusinesses().Count(); Results = new PartialEntitiesList<Business>(myBusinesses.Skip((PageNumber - 1)*PageSize).Take(PageSize).ToList()) {UnpartialTotalCount = myBusinessesCount}; return Results; } public class PartialEntitiesList<T> : List<T> { public PartialEntitiesList() { } public PartialEntitiesList(int capacity) : base(capacity) { } public PartialEntitiesList(IEnumerable<T> collection) : base(collection) { } public int UnpartialTotalCount { get; set; } }

  • Keeping user data persistent after validates_presence_of

    - by mathee
    I'm designing a question-and-answer Ruby on Rails application. After a user logs in, you can see a list of questions posed by other users. I have a link next to each of the questions to /answers/new?question_id=someNumber. That links to a page that displays the question (to remind the "answerer") above a standard form for submitting your answer. In order to display the question, I call @question = Question.find_by_id(params[:question_id]) and reference @question in the Haml view file: Question details %h2 #{h @question.title} #{h @question.description} %br/ %br/ %h1 Your answer - form_for(@answer) do |f| = f.error_messages %p = f.label :description, "Enter your response here" %br = f.text_area :description = f.hidden_field "question", :value => @question.id %p = f.submit 'Answer' The problem is that if I check validates_presence_of :description in Answer.rb, then I lose question_id if the user did not input anything into the description field when the page reloads, so I can't re-display the question for which the user is answering. How should I fix this? Is there a better way of storing the question the user is trying to answer so that I can display it above the form for entering a new answer (and perhaps in other views in the future)? If you need to see more code, please let me know.

  • Keep data with specific value on top when sorting a gridview

    - by aspNetAficionado
    Hi i have a gridview with information about documents: name, document type (policy, guidelines, forms, etc), category, etc. I want to sort the gridview alphabetically (name) and by document type, but always having the 'policy' above the other document types when document name is the same. How do I do that? eg If I do sort by DocumentName, DocumentType ('policy' maybe not be the first one in the list) but if I do sort by DocumentType , DocumentName (I would get for example all guidelines first in alphabetical order, then procedures, then policies, etc)

  • jQuery: Post form to a modal window for previewing the entered data

    - by superUntitled
    I am looking for a way to use jQuery to allow a user to look at a modal window "preview" of a form before they submit the form to be saved. I have this working with javascript, the form is posted to a file named preview.php that iterates through the posted information. The script currently opens a new window. I would like instead to use jQuery to post the form to a modal window for previewing. Does anyone have any thoughts on how to do this? This is what I am currently using: <script language="JavaScript"> function preview(form) { form.target='_blank'; form.action='http://example.com/preview.php'; form.submit(); } </script> <input type="button" value="preview" onclick='preview(this.form)'>

  • A C# collection, which behaves like C++ set or priority_queue?

    - by Wojciech
    Hello, I have written the Dijkstra's algorithm many times in C++ - I need there set or priotity_queue, both give me possibility to add an element and find the least one (using specified comparator). Now, I've got a problem when trying to write Dijkstra in C# - is there any structure which could be useful for me? I need adding and finding or erasing the least element. Using Visual Studio '08

  • .resx file data inaccessible in Visual C#

    - by dsp_099
    What I'm trying to do: include some files along with the executable to extract them later. I have two projects, both with a Resource1.resx file (and some resources included from disk). In one project, I can use File.WriteAllBytes(path, Resource1.Image); to dump the resource to disk. In another, Resource1 is does not exist. I've done this before but all I can find is information about localizations (?) when I search MSDN for how to work with Resources.

  • How to print structures in PLT Scheme so as to display their fields?

    - by tkf
    I would like code like this: (define-struct thing (a b c)) (define th (make-thing 1 2 3)) to print something like this: (make-thing 1 2 3) when I type "th" into either the DrScheme or MzScheme repl. I am using the language "pretty big" in DrScheme with output style set to "constructor". This is what I get in DrScheme: (make-thing ...) (i literally get the three dots) In MzScheme: #<thing>

  • Complexity in using Binary search and Trie

    - by user121196
    given a large list of alphabetically sorted words in a file,I need to write a program that, given a word x, determines if x is in the list. Preprocessing is ok since I will be calling this function many times over different inputs. priorties: 1. speed. 2. memory I already know I can use (n is number of words, m is average length of the words) 1. a trie, time is O(log(n)), space(best case) is O(log(n*m)), space(worst case) is O(n*m). 2. load the complete list into memory, then binary search, time is O(log(n)), space is O(n*m) I'm not sure about the complexity on tri, please correct me if they are wrong. Also are there other good approaches?

  • How to store data with N columns

    - by iconiK
    I need a way to store an int for N columns. Basically what I have is this: Armies: ArmyID - UINT UnitCount1 - UINT UnitCount2 - UINT UnitCount3 - UINT UnitCount4 - UINT ... I can't possible add a column for each and every unit, so I need a fast way to store the number of each units in an army (you might have guesses it's for a game by now). Using XML is not an option as it will be dead slow.

  • Pivot to obtain EAV data

    - by Snowy
    I have an EAV table (simple key/value in every row) and I need to take the 'value' from two of the rows and concat them into a single row with a single column. I can't seem to get through the part where I just have the pivot straight. Can anyone help me figure this out? Declare @eavHelp Table ( [Key] VARCHAR (8) NOT NULL, [Value] VARCHAR (8) NULL ) Insert Into @eavHelp Values ( 'key1' , 'aaa' ) Insert Into @eavHelp Values ( 'key2' , 'bbb' ) Select * From @eavHelp Pivot ( Min( [Value] ) For [Value] in ( hmm1 , hmm2 ) ) as Piv Where [Key] = 'key1' or [Key] = 'key2' That makes: Key hmm1 hmm2 -------- -------- -------- key1 NULL NULL key2 NULL NULL But what I want to make is: hmmmX ----- aaa;bbb

  • How do you compare music data

    - by Chris
    i want to write an app to rename sort and organize my music library (mp3's, wav's, flac's). I wanted to take a portion of the song, say the first minutes, and compare that to a database and then retrieve the song name and tag information. I have heard that you can do this with last.fm but a look through their api info didn't help. My question is, what is this called so i can google it better? nothing i am trying is helping much. This would be similar to the shazam android app. My prefered language would be java, so i can run it on a few operating systems easier, but that might be subject to change depending on how i can do it. Thanks

  • Can two managed object context share one single persistent store coordinator?

    - by mystify
    Example: I have one persistent store coordinator which uses one single persistent store. Now there are two managed object contexts, and both want to use the same persistent store. Could both simply use the same persistent store coordinator, or would I have to create two instances of NSPersistentStoreCoordinator? And if I had to, then: Would I also have to create two NSPersistentStore instances?
