  • HTML Special Entity Codes in Actionscript3/Flex

    - by BlairHippo
    I have a Flex/Actionscript 3 application that displays RSS feeds in a Text element. It strips out any HTML formatting present, but it's not handling HTML special entity codes properly -- it's rendering &mdash as the literal string instead of replacing it with an em-dash, etc. Is there any systematic way I can make it handle those codes properly, or am I going to need to manually replace those strings regex style?

  • Why are member constants available even if there are no instances of a its class?

    - by flockofcode
    1) Why are member constants available even if there are no instances of a its class? 2) Is the only reason why constant expressions need to be fully evaluated at compile time due to compiler replacing constant variable with literal value? 3) Since string is also an object, I would think the following would produce an error, but it doesn’t. Why? class A { const string b = “it works”; } thank you

  • LaTeX vs DocBook

    - by yfel
    I have only little knowledge about LaTeX, basic formatting, basic math fomulae etc.. I found that LaTeX is hard to configure to my own flavor. Recently, I've heard about Docbook, which is also a typesetting mechanism, but much easier since it uses XML. So, if my main job using LaTeX/Docbook is writing a simple document (not a class book) with some mathematics, and I want easy configuration, and a highly constomizable application, which one is better, and is there any good book on Docbook?

  • File sorting, Comparison method violates its general contract

    - by user2677383
    My file sorting comparator sometimes invoke java.lang.IllegalArgumentException in android app. I cannot figure out the reason. could you explain that? here is my code block: Comparator cc = new Comparator<File>() { @Override public int compare(File f1, File f2) { if (f1.isDirectory() && !f2.isDirectory()) { return 1; } if (f2.isDirectory() && !f1.isDirectory()) { return -1; } if ((f1.isFile() && f2.isFile()) || (f1.isDirectory() && f2.isDirectory())) { if (sort == 1) { return Util.compareFileName(f2.getName(), f1.getName()); } else if (sort == 2) { return (int) (f1.lastModified() - f2.lastModified()); } else if (sort == 3) { return (int) (f2.lastModified() - f1.lastModified()); } else if (sort == 4) { return (int) (f1.length() - f2.length()); } else if (sort == 5) { return (int) (f2.length() - f1.length()); } else return Util.compareFileName(f1.getName(), f2.getName()); } return f1.compareTo(f2); } }; Util.compareFileName is as followings: public static int compareFileName(String s1, String s2) { int thisMarker = 0; int thatMarker = 0; int s1Length = s1.length(); int s2Length = s2.length(); while (thisMarker < s1Length && thatMarker < s2Length) { String thisChunk = getChunk(s1, s1Length, thisMarker); thisMarker += thisChunk.length(); String thatChunk = getChunk(s2, s2Length, thatMarker); thatMarker += thatChunk.length(); // If both chunks contain numeric characters, sort them numerically int result = 0; if (isDigit(thisChunk.charAt(0)) && isDigit(thatChunk.charAt(0))) { // Simple chunk comparison by length. int thisChunkLength = thisChunk.length(); result = thisChunkLength - thatChunk.length(); // If equal, the first different number counts if (result == 0) { for (int i = 0; i < thisChunkLength; i++) { result = thisChunk.charAt(i) - thatChunk.charAt(i); if (result != 0) { return result; } } } } else { result = thisChunk.compareTo(thatChunk); } if (result != 0) return result; } return s1Length - s2Length; }

  • LINQ - joining multiple lists

    - by kristian
    I've looked at the 101 Linq Samples here but I can't see anything like this in that list. If I'm just not seeing a relevant example there, please link to it. If I have these 3 classes: class Student { int id; string name } class Course { int id, string name } class Enrolment { int studentId; int courseId; } How would I use LINQ to get a list of courses a student is enrolled on? (assume I have an IList of all three classes)

  • How does Response.Redirect calculate the URL for "~/folder1/folder2/some.aspx"

    - by Chris Marisic
    This might sound like a trivial problem but for some reason it is not. Instead of needing to redirect Response.Redirect("~/folder1/folder2/some.aspx") I need the location as if it behaved like string navigatingUrl = Response.Redirect("~/folder1/folder2/some.aspx") Trying to replicate this I started with string navigatingUrl = new Uri(HttpContext.Current.Request.Url, new Uri("~/folder1/folder2/some.aspx", UriKind.Relative)); This instead generates "http://www.fullRequestUrl/~/folder1/folder2/some.aspx"

  • C++ application as a service with high performance

    - by sand
    I need to provide a C++ application as a service. Client of the service and the service can be on the same machine or distributed on different machines based on the load. This application takes a ~2KB string as input and returns almost similar size of string after some processing. Turnaround time for the client should be really quick. What is the best mechanism to implement this?

  • iPhone time comparison

    - by Rob
    I am trying to figure out how to create an 'if' statement that uses a time value as a condition. For example: if (time <= 10:00) { score = 3; } else if (time <= 20:00) { score = 5; } else { score = 9; } I know that a string of "5:23" cannot be compared this way but I don't think I can just turn a string value like that directly into an integer. Any thoughts?
