• Auto-Complete Suggestions in Source Code Editor

  - by Jim

  Hello, Most IDEs (Eclipse, Netbeans, Intelij) provide contextually smart suggestions about the current statement you're writing. We would like to do the same thing (In Java for Java). We considered tokenizing the input and building our own abstract syntax trees, but quickly realized that could be a month long project in and of its self. We also started digging through the source code for the above mentioned IDEs, but it appears (correct me if I'm wrong) that the auto-complete code is pretty tightly woven with the rest of the IDE. We're wondering if anyone knows of a relatively isolated package that we could pull into our project to provide this auto-complete functionality. Thanks!

• How to get a list of unchecked checkboxes when submitting a form?

  - by SzamDev

  Hi I have this code for example : $b = ""; while ($row = mysql_fetch_array($rows)) { if ($row['enabled'] == 1) { $b = "checked"; } else { $b = "": } echo "<\input name='nam[$row[id]]' type='checkbox' value='$row[id]' $b /"; } When I execute this code, I will get a list of checkboxes, some of them are checked and others are not. I can use this code to get a list of checked checkboxes. if (isset($_POST['sub'])) { //check if form has been submitted or not $nam = $_POST['nam']; if (!empty($nam)) { foreach($nam as $k=>$val){ // proccess operation with checked checkboxes } } I need to know how I can get list of unckecked checkboxes after submitting the form. Thanks in advance.

• UTF-8 xml file shows Gibberish

  - by Adam

  I have a UTF-8 encoded xml file, which was exported from a Wordpress MySQL database. While the file is saved as UTF-8, and the encoding is UTF-8, I get gibberish instead of the Hebrew text that is supposed to be in there, which looks like this: ™×•×˜×•×ª How can I find the original encoding or charset and convert the text into proper Hebrew? PHP's mb_detect_encoding($str); returns UTF-8 Tried all sorts of php encoding functions, with different settings and input/output charsets, but they all just print different looking gibberish blocks, like: ÃâÃËÃâ¢Ãâ¢ÃËà and ?? ××©×ž× ...Any Ideas how to go about this?

• Most Lite-Weight XML Parser with XPath and Wide-char Support

  - by Mystagogue

  I want a lite-weight C++ XML parser/DOM that: Can take UTF-8 as input, and parse into UTF-16. Maybe it does this directly (ideal!), or perhaps it provides a hook for the conversion (such as taking a custom stream object that does the conversion before parsing). Offers some XPath support. I've been looking at RapidXML, the Kranf xmlParser, and pugiXML. The first two of those might permit requirement #1 by way of a hook. The third, pugiXML, supports the #2 requirement. But none of those three fulfill both requirements. What is the smallest (free) library that can handle both requirements?

• How to fetch data for AutoCompleteTextView in separate thread?

  - by Laimoncijus

  For my AutoCompleteTextView I need to fetch the data from a webservice. As it can take a little time I do not want UI thread to be not responsive, so I need somehow to fetch the data in a separate thread. For example, while fetching data from SQLite DB, it is very easy done with CursorAdapter method - runQueryOnBackgroundThread. I was looking around to other adapters like ArrayAdapter, BaseAdapter, but could not find anything similar... Is there an easy way how to achieve this? I cannot simply use ArrayAdapter directly, as the suggestions list is dynamic - I always fetch the suggestions list depending on user input, so it cannot be pre-fetched and cached for further use... If someone could give some tips or examples on this topic - would be great!

• Alternative design for a synonyms table?

  - by Majid

  I am working on an app which is to suggest alternative words/phrases for input text. I have doubts about what might be a good design for the synonyms table. Design considerations: number of synonyms is variable, i.e. football has one synonym (soccer), but in particular has two (particularly, specifically) if football is a synonym to soccer, the relation exists in the opposite direction as well. our goal is to query a word and find its synonyms we want to keep the table small and make adding new words easy What comes to my mind is a two column design with col a = word and col b = delimited list of synonyms Is there any better alternative? What about using two tables, one for words and the other for relations?

• ANDROID. Emulate Hardware Keys with an IME. Doesn't work with Dialog and Spinner

  - by shutdown11

  I have understand that the only way to inject KeyEvents in the Android System is to implement an Input Method. I have created my IME with the purpose to control from remote the device. I emulate the hardware keys using the method private void keyDownUp(int keyEventCode) { getCurrentInputConnection().sendKeyEvent( new KeyEvent(KeyEvent.ACTION_DOWN, keyEventCode)); getCurrentInputConnection().sendKeyEvent( new KeyEvent(KeyEvent.ACTION_UP, keyEventCode)); } in my class that extends InputMethodService. It works fine until an AlertDialog, or the menu of a Spinner comes in foreground. Also the windows that appears when the Menu key is problematic. My IME can't get focus on them, and the keyevents are sent to the activity behind them. Using hardware keys, the Dialog get the focus and you can select the botton on the Dialog. How can i emulate that, using the IME(or anything else)?

• Adding additional components to a web page after rendering by Wicket

  - by Andrew Fielden

  I have a requirement to create a web page using Wicket 1.5, which can present a variable number of panels to capture user input. All the panels have the same structure. The page would start off with one panel, and includes a button to dynamically add more as required. So the number of panels is unknown at the time the page is initially rendered. Effectively I'd be altering the structure of the page dynamically. This is possible in Javascript, using document.addElement() I've done a similar thing in the past by creating all the components on page load, and selectively showing/hiding components. The difference here is that the number of components (panels) is initially unknown. I'm unsure as to how this would be achieved with Wicket.

• How do I draw a filled circle onto a graphics object in a hexadecimal colour? (C#)

  - by George Powell

  I need to draw a circle onto a bitmap in a specific colour given in Hex. The "Brushes" class only gives specific colours with names. Bitmap bitmap = new Bitmap(20, 20); Graphics g = Graphics.FromImage(bitmap); g.FillEllipse(Brushes.AliceBlue, 0, 0, 19, 19); //The input parameter is not a Hex //g.FillEllipse(new Brush("#ff00ffff"), 0, 0, 19, 19); <<This is the kind of think I need. Is there a way of doing this? The exact problem: I am generating KML (for Google earth) and I am generating lots of lines with different Hex colours. The colours are generated mathematically and I need to keep it that way so I can make as many colours as I want. I need to generate a PNG icon for each of the lines that is the same colour exactly.

• Searching Database by Arbitrary Date in PHP

  - by jverdi

  Suppose you have a messaging system built in PHP with a MySQL database backend, and you would like to support searching for messages using arbitrary date strings. The database includes a messages table, with a 'date_created' field represented as a datetime. Examples of the arbitrary date strings that would be accepted by the user should mirror those accepted by strtotime. For the following examples, searches performed on March 21, 2010: "January 26, 2009" would return all messages between 2009-01-26 00:00:00 and 2009-01-27 00:00:00 "March 8" would return all messages between 2010-03-08 00:00:00 and 2010-01-26 00:00:00 "Last week" would return all messages between 2010-03-14 00:00:00 and 2010-03-21 018:25:00 "2008" would return all messages between 2008-01-01 00:00:00 and 2008-12-31 00:00:00 I began working with date_parse, but the number of variables grew quickly. I wonder if I am re-inventing the wheel. Does anyone have a suggestion that would work either as a general solution or one that would capture most of the possible input strings?

• Setting a property value on each of the results in a FetchedResults set

  - by RickiG

  Hi On my Core Data Entity "Book" i have a boolean property, 'wasViewed' (NSNumber numberWithBool) that tells me if the Book was "viewed". I would like to implement a sort of "reset" this property for all my NSManagedObjects "Book". So that I can set them all to NO between sessions. I use an NSPredicate to retrieve all the Books like this: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"wasViewed == %@", [NSNumber numberWithBool:YES]]; // code for setting entity, request etc... NSMutableArray *mutableFetchResults = [[[managedObjectContext executeFetchRequest:request error:&error] mutableCopy] autorelease]; This is working just fine, however, now I need to set up a loop, go through each Book object, something like this: for(Book *b in mutableFetchResults) { [b setWasViewed:NO] } Is there a way to perform an action on each element that fits the predicate instead of retrieving it? So instead of executeFetchRequest on a managedObjectContext it could be executeOperationOnFetchRequestResults or something along those lines. Thanks for any input given:)

• SVN - Get all commit messages for a file?

  - by davidosomething

  Is there a way to get a nice list of all commit messages sorted by file? Something like this (as you can see, I don't want the messages specific to a certain file, just show messages for the entire commit if the file was part of the commit, repeats ok): -- index.php 2010-01-02 03:04:05 * added new paragraph 2010-01-01 03:04:05 * moved header out of index.php into header.php * header.php initial check-in 2009-12-31 03:04:05 * index.php initial check-in -- header.php 2010-01-03 03:04:05 * added new meta tags 2010-01-01 03:04:05 * moved header out of index.php into header.php * header.php initial check-in Additional information: svn log filename does something similar, but I want it to do this: get a list of files that have changed between yyyy-mm-dd (r2) and yyyy-mm-dd (r4) (i.e. svn log -q -v -r 2:4 changedfiles.txt strip extraneous crap from changedfiles.txt svn log each file in that list, as in: svn log < changedfiles.txt combinedlog.txt (just pseudocode, i know svn log takes arguments not input, but can't be bothered to write it out)

• Another answer to the CAPTCHA problem?

  - by Xeoncross

  Most sites at least employ server access log checking and banning along with some kind of bot prevention measure like a CAPTCHA (those messed-up text images). The problem with CAPTCHAs is that they poss a threat to the user experience. Luckily they now come with user friendly features like refresh and audio versions. Anyway, like linux vs windows, it isn't worth the time of a spammer to customize and/or build a script to handle a custom CAPTCHA example that only pertains to one site. Therefore, I was wondering if there might be better ways to handle the whole CAPTCHA thing. In A Better CAPTCHA Peter Bromberg mentions that one way would be to convert the image to HTML and display it embedded in the page. On http://shiflett.org/ Chris simply asks users to type his name into an input. Examples like this are ways to simplifying the CAPTCHA experience while decreasing the value for spammers. Does anyone know of more good examples I could use or see any problem with the embedded image idea?

• Best practices about creating a generic object dictionary in C#? Is this bad?

  - by JimDaniel

  For clarity I am using C# 3.5/Asp.Net MVC 2 Here is what I have done: I wanted the ability to add/remove functionality to an object at run-time. So I simply added a generic object dictionary to my class like this: public Dictionary<int, object> Components { get; set; } Then I can add/remove any kind of .Net object into this dictionary at run-time. To insert an object I do something like this: var tag = new Tag(); myObject.Components.Add((int)Types.Components.Tag, tag); Then to retrieve I just do this: if(myObject.Components.ContainsKey((int)Types.Components.Tag)) { var tag = myObject.Components[(int)Types.Components.Tag] as Tag; if(tag != null) { //do stuff } } Somehow I feel sneaky doing this. It works okay, but I am wondering what you guys think about it as a best practice. Thanks for your input, Daniel

• How come checkbox state is not always passed along to PHP script?

  - by George Edison

  I have an HTML form: <form action='process.php' method='post'> <input type='checkbox' name='check_box_1' /> Check me!<br> </form> Here is a section from the PHP script process.php: echo (isset($_POST['check_box_1']))?'Set':'Not set'; The output of the script when the checkbox is set is Set But when the checkbox is not set, the output is: Not set Why is this? This seems like a very poor design because my PHP script checks a number of $_POST variables to make sure they were passed along to the script. When the $_POST['check_box_1'] value is not set, then how do I know whether the script failed to pass along the value or the checkbox was just not set?
