  • Confused about distinct/aggregate queries with (N)Hibernate

    - by nw
    I'm not sure how to approach queries that don't map 1:1 to my persistent entities - in other words, distinct and aggregate queries. For example, I need to retrieve a distinct list of property values for populating a drop-down list. Should I write a class and a mapping for the "entities" that are returned by this query? Or should I just use the native DB provider and work with native data sets instead?

  • Make namespaces backwards compatible in PHP

    - by daeliur
    So I was reading about PHP namespaces, and I realized that in versions earlier than 5.3, if you write namespace MyNamespace you get a parse error. Is there any way to avoid this i.e. make namespaces backwards-compatible, so the code doesn't simply crash?

  • How do I find matching values in a generic list

    - by TDDG
    I have anywhere from 5 to 10 generic list in an ASP.NET VB.NET web app. I would like to write a method to pass them all into, and return only the elements they all have in common. I'm looking for some ideas how to accomplish this the easiest and cleanest way possible.

  • What is the difference between these two statements (asp.net/c#/entity framework)

    - by user318573
    IEnumerable<Department> myQuery = (from D in myContext.Departments orderby D.DeptName select D); var myQuery = (from D in myContext.Departments orderby D.DeptName select D); What is the difference between these two statements above? In my little asp.net/C#/ EF4.0 app I can write them either way, and as far as how I want to use them, they both work, but there has to be a reason why I would choose one over the other?

  • Java keep printing a new line in my recursive method

    - by Abra Grace Libretto White
    I am trying to write a recursive method to print n number of asteriks in a line and create a new line at the end. So, TriangleOps.line(5); would print ***** This is the code I wrote: public static void line (int n){ if(n>0){ System.out.println("*"); line(n-1); }} instead it prints * * * * * with a lot of space at the end. Can anyone tell me how to remove the line breaks?

  • Memory Regions displayed in SMAPS output with no permissions

    - by crissangel
    If I see the output of cat /proc//smaps, I find that there are some memory regions with which no read/write/execute permissions have been associated. Also these region are mapped to inode number 0. I wanted to know how does a region end up in such a state? Is it some sort of memory leak? Can these regions be ever used again by the process?

  • Enable proper relative path in cron

    - by Webnet
    I have 2 servers that are on completely separate OS' and configurations. One properly accepts require_once '../file.php'; and the other doesn't, because it's relative to where the cron is loading I guess. How can I fix the 2nd location so that it's relative path is from the relative path of the file. I need this to work in 3 different environments (local, beta, and live) so I don't want to write a bunch of code on this page, I'd prefer a configuration adjustment if possible.

  • Is there a sorted_vector class, which supports insert() etc.?

    - by Frank
    Often, it is more efficient to use a sorted std::vector instead of a std::set. Does anyone know a library class sorted_vector, which basically has a similar interface to std::set, but inserts elements into the sorted vector (so that there are no duplicates), uses binary search to find elements, etc.? I know it's not hard to write, but probably better not to waste time and use an existing implementation anyway.

  • Matching Strings: a biological perspective

    - by sun
    Write a function, called constrainedMatchPair which takes three arguments: a tuple representing starting points for the first substring, a tuple representing starting points for the second substring, and the length of the first substring. The function should return a tuple of all members (call it n) of the first tuple for which there is an element in the second tuple (call it k) such that n+m+1 = k, where m is the length of the first substring. Complete the definition def constrainedMatchPair(firstMatch,secondMatch,length):

  • Prolog returns Out = _G431 when it suppose to return a list of lists

    - by Mandah
    createSchedule([[math109]], fall, Out). [[cs485, cs485], [cs355, cs355, cs462, cs462, cs462], [cs345, cs345, cs352, cs352, cs352, cs362, cs362, cs362, cs396, cs396, cs396], [cs330, cs330, cs330], [cs255, cs255, cs255, cs268, cs268], [math114, cs245, cs245], [math112, cs145, cs146], [math109]] Out = _G431 this is what prolog returns and the list of lists is shown by using write(Out) in prolog. Any ideas why it is showing this? Thanks

  • Where does code within Script tags go in the resulting AS class?

    - by Hanno Fietz
    I was wondering what happens to the code contained in an <mx:Script> tag. If I define a function tehre, it just becomes a member function of the generated class. But I noticed that it seems OK for the compiler if I just write some (static) method calls there (specifically, I call Font.registerFont()). I feel kind of guilty for doing this, because I have no idea what's really happening and when the code gets executed.

  • Why there are no semicolons and {} blocks in some languages

    - by Incognito
    I know the question has no practical value, but it is interesting why in some languages semicolons and {} blocks are removed although their predecessor have them. Actually it makes me nervous to write a code in Python as there are no ";" and {}. Also in new language Google-GO semicolons are also missing although it says that lexer uses a rule to insert semicolons automatically as it scans. So is there any secret :) reason for this.

  • Curl CONNECTION OPTIONS in C++

    - by cinek1lol
    HI I'd like to know how to check out the speed of a file being uploaded in real time using the curl library in c++. This is what I have written: curl_easy_getinfo(curl,CURLINFO_SPEED_UPLOAD,&c); But the manual says that it shows average speed, but even this doesn't seem to work with me, because I can only see a 0. There is one more thing: How to set an upload limit that works, because if I write this: curl_easy_setopt(curl, CURLOPT_MAX_SEND_SPEED_LARGE, 100); I get an error 502 message
