  • Namespacing technique in JavaScript, recommended? performant? issues to be aware of?

    - by Bjartr
    In a project I am working on I am structuring my code as follows MyLib = { AField:0, ASubNamespace:{ AnotherField:"value", AClass:function(param) { this.classField = param; this.classFunction = function(){ // stuff } } }, AnotherClass:function(param) { this.classField = param; this.classFunction = function(){ // stuff } } } and so on like that to do stuff like: var anInstance = new MyLib.ASubNamespace.AClass("A parameter."); Is this the right way to go about achieving namespacing? Are there performance hits, and if so, how drastic? Do performance degradations stack as I nest deeper? Are there any other issues I should be aware of when using this structure? I care about every little bit of performance because it's a library for realtime graphics, so I'm taking any overhead very seriously.

  • Should I use "User Defined Functions" in SQL server, or C#?

    - by sanity
    I have a fairly complicated mathematical function that I've been advised should be implemented as a User Defined Function in SQL Server so that it can be used efficiently from within a SQL query. The problem is that it must be very efficient as it may be executed thousands of times per second, and I subsequently heard that UDFs are very inefficient. Someone suggested that I could implement the function in C# instead, and that this would be much more efficient. What should I do?

  • Encoding GBK2312 Condundrum

    - by user792271
    I am an amateur coder and I have a small problem. My goal is to have one text input with two buttons. The first button uses a bit of Javascript called SundayMorning to translate the text (to Chinese) The second button submits the text to a URL. The URl requires that Chinese text be encoded it in GBK2312 character set. I have duct taped together various found code to the result I have now. Due to the finicky behavior of the SundayMorning Javascript, my solution is to have two input boxes, the second of which I will hide. Right now, this doesn't work: I am unable to encode the Chinese in GBK2312, no matter what I try. BONUS CONUNDRUM: The second box copies my input letter by letter as I type, but does not copy the Chinese translation that the Javascript returns. Sorry for my janky amateur code. I defer to those more clever, if you have any kind suggestions. <head> <meta http-equiv="Content-Type" content="text/html; charset=GB2312" /> <script type='text/javascript' Src='https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js'> </script> ///THIS JS TRANSLATES THE TEXT INLINE <script type="text/javascript" src="jquery.sundaymorning.js"> </script> <script type="text/javascript"> $(function() { $('#example3').sundayMorningReset(); $('#example3 input[type=image]').click(function(evt) { $.sundayMorning( $('#example3 input[type=text]').val(),{source:'en', destination:'ZH', menuLeft:evt.pageX, menuTop:evt.pageY},function(response) {$('#example3 input[type=text]').val(response.translation);});});}); </script> /// ///THIS PUTS THE CONTENT OF THE TRANSLATION BOX INTO THE SUBMISSION BOX <script type="text/javascript"> $(document).ready(function(){ var $url = $("#url"); $("#track").keyup(function() { $url.val(this.value);}); $("#track").blur(function() { $url.val(this.value);});}); </script> ///THIS PUTS THE CONTENT OF THE SUBMISSION INSIDE A URL <SCRIPT type="text/javascript"> function goToPage(url) { var initial = "http://example.com/"; var extension = ".html"; document.something.action=initial+url+extension; } </SCRIPT> </head> <body> <div id="featured"> <div id="example3"> <input type="text" name="track" id="track" value="" class="box"onkeydown="javascript:if (event.which || event.keyCode){if ((event.which == 13) || (event.keyCode == 13)) {document.getElementById('mama').click();}};"/> <input type="image" src="http://taobaofieldguide.com/images/orange-translate-button.png" id="searchsubmit" value="Translate" class="btn" /> </div> <FORM name="something" method="post" onsubmit="goToPage(this.url.value);"> <input type="text" id="url";> <INPUT type="submit" id="mama" value="GO" > </FORM> </div> </body>

  • Add a + sign to a +ve number in PHP

    - by user318466
    I need to design a function to return -ve numbers unchanged but should add a + sign at the start of the number if its alreay no present. Example: Input Output ---------------- +1 +1 1 +1 -1 -1 It will get only numeric input. function formatNum($num) { # something here..perhaps a regex? } This function is going to be called several times in echo/print so the quicker the better.

  • Name lookup for names not dependent on template parameter in VC++2008 Express. Is it a bug?

    - by Maciej H
    While experimenting a bit with C++ templates I managed to produce this simple code, for which the output is different, than I expected according to my understanding of C++ rules. void bar(double d) { std::cout << "bar(double) function called" << std::endl; } template <typename T> void foo(T t) { bar(3); } void bar(int i) { std::cout << "bar(int) function called" << std::endl; } int main() { foo(3); return 0; } When I compile this code is VC++2008 Express function bar(int) gets called. That would be the behaviour I would expect if bar(3);in the template body was dependent on the template parameter. But it's not. The rule I found here says "The C++ standard prescribes that all names that are not dependent on template parameters are bound to their present definitions when parsing a template function or class". Am I wrong, that "present definition" of bar when parsing the template function foo is the definition of void bar(double d);? Why it's not the case if I am wrong. There are no forward declarations of bar in this compilation unit.

  • Getting an Ajax response from Zend Framework Controller

    - by JavaLava
    I'm doing an Ajax request on one of my views to a Controller but I am unable to send back a response to the Ajax method. In the snippet below, I am trying to send the word 'hellopanda' back but in the alert message, I'll get data as an object. View : $.ajax({ type: "POST", url: "localhost/some-activity", data: dataString, success: function(data) { alert( "Data is: " + data); //do something with data }, error: function(data){ alert( "Data is: " + data); //do something with data }, onComplete: function(){ } }); Controller: public function someActivityAction(){ //do stuff echo "hellopanda"; } I'm pretty sure the echo is the problem. Any insights on to how to do a proper response to the view would be greatly appreciated.

  • Dynamic jQuery dialog after data append w/o reloading page. Possible?

    - by Arun
    Howdy, So I have a page with an enormous table in a CRUD interface of sorts. Each link within a span calls a jQuery UI Dialog Form which fetches it's content from another page. When the action taking place (in this case, a creation) has completed, it appends the resulting new data to the table and forces a resort of the table. This all happens within the JS and the DOM. The problem with this, is that the new table row's CRUD links don't actually trigger the dialog form creation as all the original links in spans are only scanned on document.ready and since I'm not reloading the page, the new links cannot be seen. Code is as follows: $(document).ready(function() { var $loading = $('<img src="/images/loading.gif" alt="Loading">'); $('span a').each(function() { var $dialog = $('<div></div>') .append($loading.clone()); var $link = $(this).one('click', function() { // Dialog Stuff success: function(data) { $('#studies tbody').append( '<tr>' + '<td><span><a href="./?action=update&study=' + data.study_id + '" title="Update Study">Update</a></span></td>' + '</tr>' ); fdTableSort.init(#studies); // This re-sorts the table. $(this).dialog('close'); } $link.click(function() { $dialog.dialog('open'); return false; }); return false; }); }); }); Basically, my question is if there is any way in which to trigger a jQuery re-evaluation of the pages links without forcing me to do a browser page refresh?

  • How to handle error in this case? By Exceptions or boolean or something else

    - by TP
    I am trying to create a Response class in Java which has a method void setResponse(String response); Different response subclasses will have different requirements for the response. The string that is passed to the function is received from the user. What is the correct way of handling a wrong response? Should the function throw an exception like IllegalResponseException Should the function be declared like boolean setResponse(String response, String errorMsg) and return false if the response is wrong and set the error message to the appropriate value

  • C#: Hijacking a near relative call

    - by Lex
    Alright, I'm trying to write a vary basic modification to a program NOT written by me. I DO NOT have the source to it. I also do not care if this only works for a single version of the program, so hard coding offsets is feasible. Anyways, I've found the function and where it is called in the compiled program. .text:1901C88F loc_1901C88F: ; CODE XREF: ConnectionThread+1A2j .text:1901C88F ; DATA XREF: .text:off_1901CC64o .text:1901C88F 8B C8 mov ecx, eax ; jumptable 1901C862 case 11 .text:1901C891 8B C6 mov eax, esi .text:1901C893 E8 48 C5 FF FF call ChatEvent According to IDA the full function signature is: char *__usercall ChatEvent<eax>(char *Data<eax>, unsigned int Length<ecx>) I already have all I need to patch the program during runtime, and do whatever other manipulations I need. What I need, is to be able to write a function like so: bool ProcessChat(char *Data, unsigned int Length); char *__usercall HijackFunction(char *Data, unsigned int Length){ if (ProcessChat(Data, Length)) Call OriginalChatEvent(Data, Length); } Get the jist of what I am trying to do? With stdcall function it's easy just replace the 4 byte address with my own function's address. But this is a near relative call, which is.. more annoying. So, anyone have any idea?

  • base pointer to derived class

    - by Jay
    Suppose there are Base class and Derived class. Base *A = new Base; Here A is a pointer point to Base class, and new constructs one that A points to. I also saw Base *B = new Derived; How to explain this? B is a pointer to Base Class, and a Derived class constructed and pointed by B? If there is a function derived from Base class, say, Virtual void f(), and it's been overridden in Derived class, then B->f() will invoke which version of the function? version in Base class, or version that overridden in Derived Class. What if there is a new function void g()in Derived, is B->g() going to invoke this function properly? One more is, is int *a = new double; or int *a = new int; legal?

  • ASP.net: Efficient ways to convert DataSets to GenericCollection (Of ObjectType)

    - by jlrolin
    I currently have a function that gets some data from the database and puts it into a dataset. The return type on my function is GenericCollection (Of CustomerDetails) If I do this: Dim dataset As DataSet = Read(strSQL.ToString) 'Gets Data from DB What's the most efficient way to map the dataset results to an collection of objects. More importantly, since I'm using GenericCollection, is there a way to do this in which I can call a function from the ObjectType class (CustomerDetails) that would have a means to converting that specific object. Or is there a way in which I can use a function that would handle all types? Is there a way to do something like: Return returnedResults.TransformDataSet(dataset) In which returnedResults is an object collection Of CustomerDetails, or would it simply be easier to have TransformDataSet return an object collection Of CustomerDetails by itself? Thanks for any help.

  • JQuery: loop through elements with more than one css class name that share only the first class name

    Hello, I'm trying to use JQuery to loop through several div's with more than one class name, that all have the same first css class name and each one has a different second class name, e.g. <div class="maintext blue"> </div> <div class="maintext purple"> </div> <div class="maintext chartreuse"> </div> <div class="maintext puce"> </div> <div class="maintext lime"> </div> In JQuery I have tried $(".mainText").each(function (i) $(".mainText.*").each(function (i) $(".mainText" *).each(function (i) $(".mainText .*").each(function (i) But it will not select any of the divs with class="mainText ..." thanks for considering the question.

  • jQuery reference to (this) does not work?

    - by FFish
    I have this href link with text either "attivo" or "non attivo" User can set the item to 'active' or 'closed' in the database with an ajax request $.post() I have 2 questions for these: I can't get the reference to $(this) to work.. I tried it with a normal link and it works, but not wrapped in if/else?? How can I prevent the user from clicking more than one time on the link and submitting several request? Is this a valid concern? Do I need some sort of a small timer or something? First I was thinking about a javascript confirm message, but that's pretty annoying for this function.. HTML: <dl id='album-list'> <dt id="dt-2">some title</dt> <dd id="dd-2"> some description<br /> <div class='links-right'>status: <a class='toggle-active' href='#'>non attivo</a></div> </dd> </dl> <a class="test" href="#">test</a> JS: $('dd a.toggle-active').click(function() { var a_ref = $(this); var id = a_ref.parent().parent().attr('id').substring(3); if (a_ref.text() == "non attivo") { var new_active = "active"; // for db in english $.post("ajax-aa.php", {album_id:id, album_active:new_active}, function(data) { // alert("success"); a_ref.text("non attivo"); // change href text }); } else { var new_active = "closed"; // for db in english $.post("ajax-aa.php", {album_id:id, album_active:new_active}, function(data) { // alert("success"); a_ref.text("attivo"); // change href text }); } return false; }); $('a.test').click(function() { var a_ref = $(this); $.post("ajax-aa.php", {album_id:2, album_active:"active"}, function(data) { a_ref.text("changed"); }); return false; })

The javascript is hard-coded into the HTML and not referenced by <script src=".."> Is it normal that this retrieved JS code isn't recognized upon call-time? If so, what is my alternative if I need the JS to change every time the div is update? Now
