  • How to use LINQ for CRUD with a simple SQL table?

    - by Rob Ferno
    Every LINQ blog I found there seemed around 2 years old, I understand the syntax but need more direction on creating the SQL mapping and context classes. I just need to use LINQ for 2 SQL tables I have, nothing complicated. Do folks write the SQL mapping classes by hand for such cases or is there a decent tool for this? Can someone point me in the right direction?

  • keyboard interaction with Cocoa?

    - by mactonny
    Hey guys, I am trying do write an application(server) which receives the keyboard instructions from the client and execute them on the server end. It's more like those screen recorders which records your keyboard and mouse events and replay them. For example, you pull up a textedit on the server, type whatever you like on the client and you can see those letters on the server. I have no clues what materials I should look into, any suggestions?

  • Haskell Add Function Return to List Until Certain Length

    - by kienjakenobi
    I want to write a function which takes a list and constructs a subset of that list of a certain length based on the output of a function. If I were simply interested in the first 50 elements of the sorted list xs, then I would use fst (splitAt 50 (sort xs)). However, the problem is that elements in my list rely on other elements in the same list. If I choose element p, then I MUST also choose elements q and r, even if they are not in the first 50 elements of my list. I am using a function finderFunc which takes an element a from the list xs and returns a list with the element a and all of its required elements. finderFunc works fine. Now, the challenge is to write a function which builds a list whose total length is 50 based on multiple outputs of finderFunc. Here is my attempt at this: finish :: [a] -> [a] -> [a] --This is the base case, which adds nothing to the final list finish [] fs = [] --The function is recursive, so the fs variable is necessary so that finish -- can forward the incomplete list to itself. finish ps fs -- If the final list fs is too small, add elements to it | length fs < 50 && length (fs ++ newrs) <= 50 = fs ++ finish newps newrs -- If the length is met, then add nothing to the list and quit | length fs >= 50 = finish [] fs -- These guard statements are currently lacking, not the main problem | otherwise = finish [] fs where --Sort the candidate list sortedps = sort ps --(finderFunc a) returns a list of type [a] containing a and all the -- elements which are required to go with it. This is the interesting -- bit. rs is also a subset of the candidate list ps. rs = finderFunc (head sortedps) --Remove those elements which are already in the final list, because -- there can be overlap newrs = filter (`notElem` fs) rs --Remove the elements we will add to the list from the new list -- of candidates newps = filter (`notElem` rs) ps I realize that the above if statements will, in some cases, not give me a list of exactly 50 elements. This is not the main problem, right now. The problem is that my function finish does not work at all as I would expect it to. Not only does it produce duplicate elements in the output list, but it sometimes goes far above the total number of elements I want to have in the list. The way this is written, I usually call it with an empty list, such as: finish xs [], so that the list it builds on starts as an empty list.

  • Detect *target* file size using JavaScript

    - by noblethrasher
    Hi, Would like to write a script to detect the file size of the target of a link on a web page. Right now I have a function that finds all links to PDF files (i.e. the href ends with '.pdf') and appends the string '[pdf]' to the innerText. I would like to extend it so that I can also append some text advising the user that the target is a large file (e.g. greater than 1MB). Thanks

  • Oracle - Return shortest string value in a set of rows

    - by Sridhar
    Hi, I'm trying to write a query that returns the shortest string value in the column. For ex: if ColumnA has values ABCDE, ZXDR, ERC, the query should return "ERC". I've written the following query, but I'm wondering if there is any better way to do this? BTW, the query should return a single value. select distinct ColumnA from ( select ColumnA, rank() over (order by length(ColumnA), ColumnA) len_rank from TableA where ColumnB = 'XXX' ) where len_rank <= 1 Thank you.

    I guess this should be straightforward but my host got me to switch server from zeus to apache following which the .htaccess file with existing individual 301 redirects failed to work causing an internal server error, so have commented them out for the time being. Could someone explain how to set these up to work in their new apache context? Have no apache experience Example redirect: Redirect 301 /pages/exhibitions/thegreatindoors.html http://www.klassnik.com/pages/thegreatindoors.html Read a lot about mod rewrites etc but not sure what to write.

  • Does knowing a Natural Language well help with Programming?

    - by Earlz
    We all hear that math at least helps a little bit with programming. My question though, does English or other natural language skills help with programming? I know it has to help with technical documentation, but what about actual programming? Are certain constructs in a programming language also there in natural languages? Does knowing how to write a 20 page research paper help with writing a 20k loc programming project?

  • How do I connect StaticListableBeanFactory with ClassPathXmlApplicationContext?

    - by Aaron Digulla
    In the setup of my test cases, I have this code: ApplicationContext context = new ClassPathXmlApplicationContext( "spring/common.xml" ); StaticListableBeanFactory testBeanFactory = new StaticListableBeanFactory(); How do I connect the two in such a way that tests can register beans in the testBeanFactory during setup and the rest of the application uses them instead of the ones defined in common.xml? Note: I need to mix a static (common.xml) and a dynamic configuration. I can't use XML for the latter because that would mean to write 1000 XML files.

  • Make sure bad patterns don't come back after refactoring

    - by Let_Me_Be
    I'm refactoring an old C code. The code has absolutely no layered architecture (everything is being accessed by everything) and I'm trying to change that. I would like to cut direct access to structure members (at least write for now) and only allow access through access functions. Is there some tool (or perhaps directly the compiler) that could check this rule for me? I need this since I'm maintaining a fork and the upstream isn't very concerned with code quality.
