    - by George
    Is it possible to mimic IQueryable with NHibernate? I was looking at Nhibernate docs and for what i could tell, it always returns a List of objects, that have it's attributes indexed by a integer. Ok, perfect, that works. But is there a way to retrieve objects like LINQ? With something like IQueryable? Thanks

  • Windows Mobile browser history

    - by kurige
    How can I retrieve a list of urls a user has visited on a Windows Mobile phone? I've written a program that successfully retrieves the visited urls in a user's cache, using FindFirstUrlCacheEntry and FindNextUrlCacheEntry - but as I understand it this is not the same as the user's actual web history. In any case it does not seem to give correct results.

  • Java: error handling with try-catch, empty-try-catch, dummy-return

    - by HH
    A searh uses recursively defined function that easily throws exceptions. I have tried 3 ways to handle exeptions: to ignore with an empty-try-catch() add-dummy-return stop err-propagation due to exeption throw a specific except. (this part I don't really understand. If I throw except, can I force it to continue elsewhere, not continuing the old except-thrown-path?) Some exceptions I do not realy care like during execution removed files -exception (NullPointer) but some I really do like unknown things. Possible exceptions: // 1. if a temp-file or some other file removed during execution -> except. // 2. if no permiss. -> except. // 3. ? --> except. The code is Very import for the whole program. I earlier added clittered-checks, try-catches, avoided-empty-try-catches but it really blurred the logic. Some stoned result here would make the code later much easier to maintain. It was annoying to track random exeptions due to some random temp-file removal! How would you handle exceptions for the critical part? Code public class Find { private Stack<File> fs=new Stack<File>(); private Stack<File> ds=new Stack<File>(); public Stack<File> getD(){ return ds;} public Stack<File> getF(){ return fs;} public Find(String path) { // setting this type of special checks due to errs // propagation makes the code clittered if(path==null) { System.out.println("NULL in Find(path)"); System.exit(9); } this.walk(path); } private void walk( String path ) { File root = new File( path ); File[] list = root.listFiles(); //TODO: dangerous with empty try-catch?! try{ for ( File f : list ) { if ( f.isDirectory() ) { walk( f.getAbsolutePath() ); ds.push(f); } else { fs.push(f); } } }catch(Exception e){e.printStackTrace();} } } Code refactored from here.

  • Java library for CSS cleanup

    - by ndn
    For a rich text editor that has to handle pasted HTML code from MS Office applications, I'm looking for a Java library that cleans up the content of all "style" attributes in HTML elements, so that only some CSS attributes are left: background-color border color font-family font-weight font-style list-style-type text-align text-decoration vertical-align For creating a well-formed HTML document, I can use JTidy. For HTML element transformations (removing unwanted elements), I can use http://htmlparser.sourceforge.net/ Is there anything comparable for CSS attributes?

  • Insert unicode strings into CleverCSS

    - by Brian M. Hunt
    How can one insert a Unicode string CSS into CleverCSS? In particular, how could one produce the following CSS using CleverCSS: li:after { content: "\00BB \0020"; } I've figured out CleverCSS's parsing rules, but suffice that the permutations I've thought sensible have failed, for example: li: content: "\\00BB \\0020" // becomes content: 'BB 0' EDIT: My other examples and the rest of my post weren't saved. Suffice that I had a longer list of examples that also failed, as did my closing which was something like: I'd be grateful for any thoughts and input. Brian

But jQuery isn't aware of these new items when they get loaded into the page, and I'm not being able to make them sortable. I made some trials with jQuery Live, but didn't get anywhere whit that...

  • Ruby Net::SMTP - Send email with bcc: recipients

    - by Jay Godse
    I would like to use Ruby Net::SMTP to send email. The routine send_message( msgstr, from_addr, *to_addrs ) works well in my code for sending email, but it is not clear from this API how to send email to a list of people that need to be blind copied (bcc:). Am I missing something, or is it just not possible with Net::SMTP?
