• jQuery - getting the id of the item selected

  - by John Leonard

  I have a basic jQuery selector question. Let's say I'm parsing JSON and generating a row of data for each item in my result set. On each item row, I want an action button. What is the best practice to script that button so its click action can reference the data specific to that row? Starting with the block below, how do I generate a 'Click Me' button that when clicked will alert with its json data? $.getJSON(url,params,function(json){ if(json.items){ $.each(json.items, function(i, n){ var item = json.items[i];

• Why does std::map operator[] create an object if the key doesn't exist?

  - by n1ck

  Hi, I'm pretty sure I already saw this question somewhere (comp.lang.c++? Google doesn't seem to find it there either) but a quick search here doesn't seem to find it so here it is: Why does the std::map operator[] create an object if the key doesn't exist? I don't know but for me this seems counter-intuitive if you compare to most other operator[] (like std::vector) where if you use it you must be sure that the index exists. I'm wondering what's the rationale for implementing this behavior in std::map. Like I said wouldn't it be more intuitive to act more like an index in a vector and crash (well undefined behavior I guess) when accessed with an invalid key? Refining my question after seeing the answers: Ok so far I got a lot of answers saying basically it's cheap so why not or things similar. I totally agree with that but why not use a dedicated function for that (I think one of the comment said that in java there is no operator[] and the function is called put)? My point is why doesn't map operator[] work like a vector? If I use operator[] on an out of range index on a vector I wouldn't like it to insert an element even if it was cheap because that probably mean an error in my code. My point is why isn't it the same thing with map. I mean, for me, using operator[] on a map would mean: i know this key already exist (for whatever reason, i just inserted it, I have redundancy somewhere, whatever). I think it would be more intuitive that way. That said what are the advantage of doing the current behavior with operator[] (and only for that, I agree that a function with the current behavior should be there, just not operator[])? Maybe it give clearer code that way? I don't know. Another answer was that it already existed that way so why not keep it but then, probably when they (the ones before stl) choose to implement it that way they found it provided an advantage or something? So my question is basically: why choose to implement it that way, meaning a somewhat lack of consistency with other operator[]. What benefit do it give? Thanks

• How to use sound and images in a Java applet?

  - by Click Upvote

  Question 1: How should I structure my project so the sound and images files can be loaded most easily? Right now, I have the folder: C:\java\pacman with the sub-directory C:\java\pacman\src containing all the code, and C:\java\pacman\assets containing the images and .wav files. Is this the best structure or should I put the assets somewhere else? Question 2: What's the best way to refer to the images/sounds without using the full path e.g C:\java\pacman\assets\something.png to them? If I use the getCodeBase() function it seems to refer to the C:\java\pacman\bin instead of C:\java\pacman\. I want to use such a function/class which would work automatically when i compile the applet in a jar as well as right now when I test the applet through eclipse. Question 3: How should I load the images/sounds? This is what I'm using now: 1) For general images: import java.awt.Image; public Image getImg(String file) { //imgDir in this case is a hardcoded string containing //"C:\\java\\pacman\\assets\\" file=imgDir + file; return new ImageIcon(file).getImage(); } The images returned from this function are used in the drawImage method of the Graphics class in the paint method of the applet. 2) For a buffered image, which is used to get subImages and load sprites from a sprite sheet: public BufferedImage getSheet() throws IOException { return ImageIO.read(new File(img.getPath("pacman-sprites.png"))); } Later: public void loadSprites() { BufferedImage sheet; try { sheet=getSheet(); redGhost.setNormalImg(sheet.getSubimage(0, 60, 20, 20)); redGhost.setUpImg(sheet.getSubimage(0, 60, 20, 20)); redGhost.setDownImg(sheet.getSubimage(30, 60, 20, 20)); redGhost.setLeftImg(sheet.getSubimage(30, 60, 20, 20)); redGhost.setRightImg(sheet.getSubimage(60, 60, 20, 20)); } catch (IOException e) { System.out.println("Couldnt open file!"); System.out.println(e.getLocalizedMessage()); } } 3) For sound files: import sun.audio.*; import java.io.*; public synchronized void play() { try { InputStream in = new FileInputStream(filename); AudioStream as = new AudioStream(in); AudioPlayer.player.start(as); } catch (IOException e) { e.printStackTrace(); } }

• Chrome Extension - Dynamic Right-Click Menu

  - by user1277607

  I am trying to create an option in the right-click menu that is dynamic based on the user's action. If the user selects some text, then right-clicks, the option will say "Display It". If the user right-clicks without selecting some text, the option will say "Select Some Text First" and be grayed out. I am wondering how do I achieve this? I currently have it so that the option will appear only when the user has selected some text. I am unsure how to modify it to meet my second requirements. chrome.contextMenus.create ({ title:"Display It!", contexts:["selection"], onclick:function(info,tab) { chrome.tabs.sendRequest( tab.id, {callFunction: "displaySidebar", info: info}, function(response) {console.log(response);} ); } });

• How to create a GtkImage from a Cairo context?

  - by Zurbo82

  I got a paint function that works using a Cairo context and the end result should be a GtkImage (without intermediate image creation). I tried to use the gdk_cairo_create function but this code: ... GdkPixbuf *pixbuf = gdk_pixbuf_new (GDK_COLORSPACE_RGB, FALSE, 8, 22, 22); GtkWidget *image = gtk_image_new_from_pixbuf (pixbuf); GdkDrawable *drawable = image->window; cairo_t *ctx = gdk_cairo_create (drawable); my_cairo_paint_function (ctx); ... fails with: Gdk-CRITICAL **: IA__gdk_cairo_create: assertion `GDK_IS_DRAWABLE (drawable)' failed Same with a simple: #include <gtk/gtk.h> #include <cairo.h> int main (int argc, char *argv[]) { gtk_init(&argc, &argv); cairo_t *ctx = gdk_cairo_create (gtk_widget_get_window (gtk_image_new_from_file ("foobar.png"))); gtk_main(); return 0; } I don't understand why this fails. Any help is appreciated!

• How to write gSOAP server using VC++ (VS2008)?

  - by Falcon

  Hi, I have downloaded gSOAP2.8 from sourceforge. I want to use it for writting a gsoap based server. I need to be able to invoke my C++ code from PHP UI. E.g. My php page would show something like: $res = a + b = ? [Submit] When submit button is clicked I want these parameters to be passed to my c++ function lets say compute_sum() ... and this function should be invoked with these parameters, and the results given back to my php page. I want to write this gsoap based c++ server. Can someone please help me with getting started with it? I need to know: 1] What kind of c++ code it should it be? (Windows console app, or a windows service) 2] How do I launch this server? (Would it need to be a webservice, hosted over something like apache?) Please advise and guide. Regards, Falcon

• JUnit for Functions with Void Return Values

  - by RobotNerd

  I've been working on a Java application where I have to use JUnit for testing. I am learning it as I go. So far I find it to be useful, especially when used in conjunction with the Eclipse JUnit plugin. After playing around a bit, I developed a consistent method for building my unit tests for functions with no return values. I wanted to share it here and ask others to comment. Do you have any suggested improvements or alternative ways to accomplish the same goal? Common Return Values First, there's an enumeration which is used to store values representing test outcomes. public enum UnitTestReturnValues { noException, unexpectedException // etc... } Generalized Test Let's say a unit test is being written for: public class SomeClass { public void targetFunction (int x, int y) { // ... } } The JUnit test class would be created: import junit.framework.TestCase; public class TestSomeClass extends TestCase { // ... } Within this class, I create a function which is used for every call to the target function being tested. It catches all exceptions and returns a message based on the outcome. For example: public class TestSomeClass extends TestCase { private UnitTestReturnValues callTargetFunction (int x, int y) { UnitTestReturnValues outcome = UnitTestReturnValues.noException; SomeClass testObj = new SomeClass (); try { testObj.targetFunction (x, y); } catch (Exception e) { UnitTestReturnValues.unexpectedException; } return outcome; } } JUnit Tests Functions called by JUnit begin with a lowercase "test" in the function name, and they fail at the first failed assertion. To run multiple tests on the targetFunction above, it would be written as: public class TestSomeClass extends TestCase { public void testTargetFunctionNegatives () { assertEquals ( callTargetFunction (-1, -1), UnitTestReturnValues.noException); } public void testTargetFunctionZeros () { assertEquals ( callTargetFunction (0, 0), UnitTestReturnValues.noException); } // and so on... } Please let me know if you have any suggestions or improvements. Keep in mind that I am in the process of learning how to use JUnit, so I'm sure there are existing tools available that might make this process easier. Thanks!

• PyGTK: Radiobuttons are still displayed after removal

  - by canavanin

  Hi everyone! I am using PyGTK and the gtk.assistant. On one page I would like to display two radiobuttons in case the user selected a certain option on a previous page. The labels of the buttons - and whether the buttons are to be present at all - are to depend entirely on that earlier selection. Furthermore, if the user goes back and changes that selection, the page containing the radiobuttons is to be updated accordingly. I have got as far as having the radiobuttons displayed when necessary, and with the correct labels. The trouble is that if I go back and change the determining selection, or if I move one page further than the 'radiobutton page' and then move back, the buttons are not only not removed (in case that would have been required), their number has also doubled. To show you what I'm doing, here's part of my code (I've left out bits that do unrelated things, that's why the function name doesn't fit). The function is called when the "prepare" signal is emitted prior to construction of the 'radiobutten page'. def make_class_skills_treestore(self): print self.trained_by_default_hbox.get_children() # PRINT 1 for child in self.trained_by_default_hbox.get_children(): if type(child) == gtk.RadioButton: self.trained_by_default_hbox.remove(child) #child.destroy() # <-- removed the labels, but not the buttons print self.trained_by_default_hbox.get_children() # PRINT 2 class_skills = self.data.data['classes'][selected_class].class_skills.values() default_trained_count = (class_skills.count([True, True]) , class_skills.count([True, False])) num_default_trained_skills = default_trained_count[1] / 2 # you have to pick one of a pair --> don't # count each as trained by default for i in range(default_trained_count[0]): # those are trained by default --> no choice num_default_trained_skills +=1 selected_class = self.get_classes_key_from_class_selection() if default_trained_count[1]: for skill in self.data.data['classes'][selected_class].class_skills.keys(): if self.data.data['classes'][selected_class].class_skills[skill] == [ True, False ] and not self.default_radio: self.default_radio.append(gtk.RadioButton(group=None, label=skill)) elif self.data.data['classes'][selected_class].class_skills[skill] == [ True, False ] and self.default_radio: self.default_radio.append(gtk.RadioButton(group=self.default_radio[0], label=skill)) if self.default_radio: for radio in self.default_radio: self.trained_by_default_hbox.add(radio) self.trained_by_default_hbox.show_all() self.trained_by_default_hbox and self.trained_by_default_label, as well as self.default_radio stem from the above function's class. I have two print statements (PRINT 1 and PRINT 2) in there for debugging. Here's what they give me: PRINT 1: [<gtk.Label object at 0x8fc4c84 (GtkLabel at 0x90a2f20)>, <gtk.RadioButton object at 0x8fc4d4c (GtkRadioButton at 0x90e4018)>, <gtk.RadioButton object at 0x8fc4cac (GtkRadioButton at 0x90ceec0)>] PRINT 2: [<gtk.Label object at 0x8fc4c84 (GtkLabel at 0x90a2f20)>] So the buttons have indeed been removed, yet they still show up on the page. I know the code requires some refactoring, but first I'd like to get it to work at all... If someone could help me out that would be great! Thanks a lot in advance for your replies - any kind of help is highly appreciated.

• make db connection persistent throught zend framework

  - by kamikaze_pilot

  I'm using zend framework. currently everytime I need to use the db I go ahead and connect to the DB: function connect(){ $connParams = array("host" => $host, "port" => $port, "username" => $username, "password" => $password, "dbname" => $dbname); $db = new Zend_Db_Adapter_Pdo_Mysql($connParams); return $db } so I would just call the connect() function everytime I need to use the db My question is...suppose I want to reuse $db everywhere in my site and only connect once in the very initial stage of the site load and then close the connection right before the site gets sent to the user, what would be the best practice to accomplish this? Which file in Zend should I save $db in, what method should I use to save it (global variable?), and which file should I do the connection closing in?

• How to enable i18n from within setup_app in websetup.py ? (formatted resend)

  - by daniel

  From within the setup_app function (websetup.py) of a pylons i18n application, which is making use of a db, I was trying to initiate multilingual content to be inserted into the db. To do so the idea was something like: #necessary imports here def setup_app(command, conf, vars): .... for lang in langs: set_lang(lang) content=model.Content() content.content=_('content') Session.add(content) Session.commit() Unfortunately it seems that it doesn't work. the set_lang code line is firing an exception as follows: File ".. i18n/translation.py", line 179, in set_lang translator = _get_translator(lang, **kwargs) File ".. i18n/translation.py", line 160, in _get_translator localedir = os.path.join(rootdir, 'i18n') File ".. /posixpath.py", line 67, in join elif path == '' or path.endswith('/'): AttributeError: 'NoneType' object has no attribute 'endswith' Actually I'm even not sure it could be possible launching i18n mechanisms from within this setup_app function without an active request object. Anyone has tried some trick on a similar story ?

  I'm successfully using jeditable to submit via a function using jQuery.ajax and the async : false option , but am having an issue aborting if an error is returned. How can I get the edit box to stay activated and / or revert back to the original value if there are errors? I'm returning http status codes. so something like async : false .ajax submit here... if (xhr.status == 200) { return value; else { alert ('returned error'); // keep edit box activated but available for another try, or revert back to original value } I tried not returning a value from the function, which keeps the edit box activated and ready for another submit, but then the ESC key doesn't work anymore and if I click outside the edit area, the edit box stays.

• bulk update/delete entities of different kind in db.run_in_transaction

  Here goes pseudo code of bulk update/delete entities of different kind in single transaction. Note that Album and Song entities have AlbumGroup as root entity. class AlbumGroup: pass class Album: group = db.ReferenceProperty(reference_class=AlbumGroup,collection_name="albums") class Song: album = db.ReferenceProperty(reference_class=Album,collection_name="songs") def bulk_update_album_group(album_group): updated = [album_group] deleted = [] for album in album_group.albums: updated.append(album) for song in album.songs: if song.is_updated: updated.append(song) if song.is_deleted: deleted.append(song) db.put(updated) db.delete(deleted) a = AlbumGroup.all().filter("...").get() # bulk update/delete album group. for simplicity, album cannot be deleted. db.run_in_transaction(bulk_update_album_group,a) But I met a famous "Only Ancestor Queries in Transactions" error at the iterating reference properties like album.songs or album_group.albums. I guess ancestor() filter does not help because those entities are modified in memory. Should I not to iterate reference property in transaction function and always provide them as function parameters like def bulk_update_album_group(updated,deleted): ??? Is there any good coding pattern for this situation?

I'm trying to pull out the 2 sets of digits from strings of the form: 12309123098_102938120938120938 1321312_103810312032123 123123123_10983094854905490 38293827_1293120938129308 I'm using the following code to process each string: if($string && $string =~ /^(\d)+_(\d)+$/) { if(IsInteger($1) && IsInteger($2)) { print "success ('$1','$2')"; } else { print "fail"; } } Where the IsInterger() function is as follows: sub IsInteger { my $integer = shift; if($integer && $integer =~ /^\d+$/) { return 1; } return; } This function seems to work most of the time but fails on the following for some reason: 1287123437_1268098784380 1287123437_1267589971660 Any ideas on why these fail while others succeed? Thanks in advance for your help!

• how to use multiple $_name using extends Zend_Db_Table_Abstract in zend frame work.

  - by karthik

  we tried to give our tables(users,messages) like this in two different abstract classes but it is not working. This is included in a file childconnect1.php ,is there any relation between the file name(childconnect1.php) and the class(Application_Model_childconnect1). class Application_Model_childconnect1 extends Zend_Db_Table_Abstract { protected $_name = 'users'; public function loginvalidation($username,$pwd) { $row = $this->fetchRow('UserName = \'' . $username . '\'and UserPW = \''. $pwd . '\''); if (!$row) { $msg="invalid"; return $msg; } else { return $row->toArray(); } } } class Application_Model_childconnect2 extends Zend_Db_Table_Abstract { protected $_name = 'messages'; public function replymessage($message) { $data=array( 'MessageText'=>$message ); $this->insert($data); } }
