• PHP: How to overwrite values in one array with values from another without adding new keys to the ar

  - by Svish

  I have an array with default settings, and one array with user-specified settings. I want to merge these two arrays so that the default settings gets overwritten with the user-specified ones. I have tried to use array_merge, which does the overwriting like I want, but it also adds new settings if the user has specified settings that doesn't exist in the default ones. Is there a better function I can use for this than array_merge? Or is there a function I can use to filter the user-specified array so that it only contains keys that also exist in the default settings array? (PHP version 5.3.0) Example of what I want $default = array('a' => 1, 'b' => 2); $user = array('b' => 3, 'c' => 4); // Somehow merge $user into $default so we end up with this: Array ( [a] => 1 [b] => 3 )

• How does jQuery have asynchronous functions?

  - by Sam.Rueby

  I'm surprised I can't find a clear answer to this. So, in jQuery, you can do this: $(someElements).fadeOut(1000); $(someElements).remove(); Which, will start a fadeOut animation, but before it finishes executing in the 1 second duration, the elements are removed from the DOM. But how is this possible? I keep reading the JavaScript is single threaded. ( Is javascript guaranteed to be single-threaded? ) This question is not "How do I fix this?" I know I can do either: $(someElements).fadeOut(1000).promise().done(function() { $(someElements).remove();});, or even better:$(someElements).fadeOut(1000, function() { $(this).remove(); } ); What I don't understand is how JavaScript runs in a "single thread" but I'm able to use these jQuery functions that execute asynchronously and visibly see the DOM change in different places at the same time. How does it work?

• VBScript Permission Denied on CopyFile

  I'm running a VBScript in SQL Agent but I get a 'Permission Denied' on line 34 (the first copy attempt).

• Crypto++ AES Decrypt how to?

  - by indigoOrange

  There are next to no noob guides to crypto++ out there. Or none that I've found anyway. What I want to do is decrypt an array of uchars I generate with another AES encrypter. Where would I start? I have the library built and linking grand. Do I need to set anything up or do I just call a function on my array (and if so what function) ? I'd really appreshiate some help from someone who knows this stuff. Thanks

• Jet Database (ms access) ExecuteNonQuery - Can I make it faster?

  - by bluebill

  Hi all, I have this generic routine that I wrote that takes a list of sql strings and executes them against the database. Is there any way I can make this work faster? Typically it'll see maybe 200 inserts or deletes or updates at a time. Sometimes there is a mixture of updates, inserts and deletes. Would it be a good idea to separate the queries by type (i.e. group inserts together, then updates and then deletes)? I am running this against an ms access database and using vb.net 2005. Public Function ExecuteNonQuery(ByVal sql As List(Of String), ByVal dbConnection as String) As Integer If sql Is Nothing OrElse sql.Count = 0 Then Return 0 Dim recordCount As Integer = 0 Using connection As New OleDb.OleDbConnection(dbConnection) connection.Open() Dim transaction As OleDb.OleDbTransaction = connection.BeginTransaction() 'Using cmd As New OleDb.OleDbCommand() Using cmd As OleDb.OleDbCommand = connection.CreateCommand cmd.Connection = connection cmd.Transaction = transaction For Each s As String In sql If Not String.IsNullOrEmpty(s) Then cmd.CommandText = s recordCount += cmd.ExecuteNonQuery() End If Next transaction.Commit() End Using End Using Return recordCount End Function

• jQuery UI Element vs Dojo (Dijit) Form Element

  - by Muers

  Dojo seems to have a useful feature in that it can setup event handlers and default options, etc for Dijit.form elements as it is inserting it into the DOM. For example, Dojo: var slider = new dijit.form.HorizontalSlider({ name: sliderContainerId+'_slider', value: sliderValue, minimum: sliderMax, maximum: sliderMin, onChange: function(value){ // some event handling logic } }, sliderContainerId); However, the jQuery UI Slider traditionally is applied to DOM elements that already exist: $( sliderContainerId ).slider({ value:100, min: 0, max: 500, step: 50, slide: function( event, ui ) { $( "#amount" ).val( "$" + ui.value ); } }); I need to be able to 'programmatically' create new Sliders (and other form elements), but I'm not sure how that could be achieved with the way jQuery is structured? Maybe I'm missing something obvious here.... MTIA

• 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.

• $("body").scrollTop() doesn't update in safari

  - by Kristoffer Nolgren

  I'm working on a website: http://beta.projektopia.se/ the body has several background-images that are updated on scroll like this: $(document).ready(function(){ $(document).scroll(function(){ var scrollfactor=$("body").scrollTop()*0.2; var centerscrollpos =scrollfactor+613; var docheight = $(document).height(); var windowheight = $(window).height(); var bottompos = (docheight-980)-((docheight-windowheight)*0.2)+scrollfactor; var scrollpos = 'center '+scrollfactor+'px,center '+bottompos+'px, center '+ centerscrollpos+'px,center 0px'; $("body").css("background-position", scrollpos); }); }); Lots of calculations, but the important thing is that a scrollpos is created that should change the position of the background when you scroll, to create a parallax-effect. It works great in chrome, but in firefox, the variable scrollfactor, that is suppose to get the current scroll-position, doesn't update. ps, some people have this issue due to lack of correct doctype. I believe i have declared it correctly like this: <!DOCTYPE html>

• Track only iframe history

  - by evanwong

  I have a page which contains an iframe and I want to track the history of the iframe only. I tried to use the history object like this: <!DOCTYPE html> <html> <head> <title></title> <script type="text/javascript"> function checkFrameHistory() { alert(window.frames["test2"].history.length); } function checkThisHistory() { alert(history.length); } </script> </head> <body> <iframe name="test2" src="test2.html"></iframe> <div> <input type="button" onclick="checkFrameHistory()" value="Frame history"/> <input type="button" onclick="checkThisHistory()" value="This history"/> </div> </body> </html> test2.html <!DOCTYPE html> <html> <head> <title></title> <script type="text/javascript"> function checkMyHistory() { alert(history.length); } </script> </head> <body> <div> Test2 </div> <div> <input type="button" onclick="checkMyHistory()" value="My history"/> </div> </body> </html> but it actually gave me the history including the parent window. For instance, I went to another site in the main window and came back to my iframe test site. Both window.frames["test2"].history.length and history.length still gave me the same count by increasing the length by 2. Did I do it wrong? Is there a way to track only the iframe history?

• Override default javascript functionality with jQuery

  - by deth4uall

  I am trying to overwrite a JavaScript on change event in the below code with jQuery however I believe that the inline JavaScript is taking priority over the jQuery functionality declared. Essentially I am trying to have an AJAX version of my site which includes an additional JavaScript file. I need this functionality to still work without the additional AJAX version, but I am not sure as to whether I should include it in the main JavaScript file or leave it inline like it is right now. Any suggestions and information regarding them would be greatly appreciated! Thanks! <form action="/cityhall/villages/" method="post" name="submit_village"> <select name="village" onchange="document.submit_village.submit();"> <option value=""></option> </select> </form> I am trying to use the jQuery Form Plugin to submit the posts to the PHP to handle the requests as follows: var bank_load_options = { target: '#content', beforeSubmit: showRequest, success: showResponse }; $('form.get_pages').livequery(function(){ $(this).ajaxForm(bank_load_options); return false; }); I modified the code as following: <form action="/cityhall/villages/" method="post" id="submit_village" name="submit_village"> <select name="village" class="get_pages" rel="submit_village"> <option value=""></option> </select> </form> <script> # main JavaScript $('.get_pages').live('change',function(e){ var submit_page = $(this).attr('rel'); $("#"+submit_page).submit(); }); # ajax JavaScript var bank_load_options = { target: '#content', beforeSubmit: showRequest, success: showResponse }; $('.get_pages').live('change',function(){ var submit_page = $(this).attr('rel'); $("#"+submit_page).ajaxForm(get_pages_load_options); return false; }); </script> However now it only runs every other option when I change it.

• 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

• jQuery event binding does not work properly or i can't make it properly working

  - by Saiful

  HTML: <input id="email" name="email" type=text /> <input id="password name="password" type="password" /> JavaScript: var fields = ["email","password"]; for (var i in fields) { var field = $("#"+fields[i]); field.bind({ focus: function() { field.css("border-color","#f00"); }, blur: function() { field.css("border-color","#000"); } }); } My desire action will be as follows: When I place cursor on any of the above fields the input field's border will be red. When I take away the cursor from the field it's border will be black. But the event is occurs only for the password filed whether I place and take away cursor form any of the above fields.

• 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(); } }

• Toastr.js notifications as modal notfication

  - by Maxsteel

  I know it's not what toastr (or toast notifs in general) are meant to be used for, but I want to use them as a modal notification. My idea is following. On toast show: toastr.options.onShown = function() { //Create an overlay on the entire page} Overlay: #overlay { background-color: rgba(0, 0, 0, 0.8); z-index: 999; position: absolute; left: 0; top: 0; width: 100%; height: 100%; display: none; } And on toast close: toastr.options.onHidden = function() { //make overlay go away } Also, I'm setting timeout of toast to 0 so it won't disappear by itself. Question: I want the toast notification to stay atop the overlay and not behind it as overlay will cover everything. How can I do it?

• I have a ConnectException that isn't being caught for some reason

  - by aakbari1024

  I'm working on an Android application that uses sockets. I have a function called initializeStreams() which opens the socket and attempts a connection. This function throws a ConnectException if the connection could not be established. But for some reason, in the code that calls initializeStreams(), which has a catch block for ConnectException, the log prints out its own stack trace for the exception instead of going to the catch block. The catch block is never reached at all, even though the exact exception is being thrown. Here's the code: The try block: try { initializeStreams(); /* drivesList = new ArrayList<String>(); drivesList = enumerateDrives();*/ } catch (ConnectException e) { //Log.i(TAG, "caught connect exception"); /*loadingProgress.dismiss(); retryConnection();*/ } initializeStreams(): public void initializeStreams() throws ConnectException { try { Log.i(TAG, "Attempting to connect"); requestSocket = new Socket(SERVER_ADDR, PORT); /* other code */ } catch (IOException e) { e.printStackTrace(); } I can't figure this out, so any help would be much appreciated. }

• How can I print N array elements with delimiters per line?

  - by Mark B

  I have an array in Perl I want to print with space delimiters between each element, except every 10th element which should be newline delimited. There aren't any spaces in the elements if that matters. I've written a function to do it with for and a counter, but I wondered if there's a better/shorter/canonical Perl way, perhaps a special join syntax or similar. My function to illustrate: sub PrintArrayWithNewlines { my $counter = 0; my $newlineIndex = shift @_; foreach my $item (@_) { ++$counter; print "$item"; if($counter == $newlineIndex) { $counter = 0; print "\n"; } else { print " "; } } }
