• What's the most efficient way to manage large datasets with Javascript/jQuery in IE?

  - by RenderIn

  I have a search that returns JSON, which I then transform into a HTML table in Javascript. It repeatedly calls the jQuery.append() method, once for each row. I have a modern machine, and the Firefox response time is acceptable. But in IE 8 it is unbearably slow. I decided to move the transformation from data to HTML into the server-side PHP, changing the return type from JSON to HTML. Now, rather than calling the jQuery.append() time repeatedly, I call the jQuery.html() method once with the entire table. I noticed Firefox got faster, but IE got slower. These results are anecdotal and I have not done any benchmarking, but the IE performance is very disappointing. Is there something I can do to speed up the manipulation of large amounts of data in IE or is it simply a bad idea to process very much data at once with AJAX/Javascript?

• Replace the content of a tag with a certain class

  - by fire

  I am looking for suitable replacement code that allows me replace the content inside of any HTML tag that has a certain class e.g. $class = "blah"; $content = "new content"; $html = '<div class="blah">hello world</div>'; // code to replace, $html now looks like: // <div class="blah">new content</div> Bare in mind that: It wont necessarily be a div, it could be <h2 class="blah"> The class can have more than one class and still needs to be replaced e.g. <div class="foo blah green">hello world</div> I am thinking regular expressions should be able to do this, if not I am open to other suggestions such as using the DOM class (although I would rather avoid this if possible because it has to be PHP4 compatible).

• Programmatic binding of accelerators in wxPython

  - by Inductiveload

  I am trying to programmatically create and bind a table of accelerators in wxPython in a loop so that I don't need to worry about getting and assigning new IDs to each accelerators (and with a view to inhaling the handler list from some external resource, rather than hard-coding them). I also pass in some arguments to the handler via a lambda since a lot of my handlers will be the same but with different parameters (move, zoom, etc). The class is subclassed from wx.Frame and setup_accelerators() is called during initialisation. def setup_accelerators(self): bindings = [ (wx.ACCEL_CTRL, wx.WXK_UP, self.on_move, 'up'), (wx.ACCEL_CTRL, wx.WXK_DOWN, self.on_move, 'down'), (wx.ACCEL_CTRL, wx.WXK_LEFT, self.on_move, 'left'), (wx.ACCEL_CTRL, wx.WXK_RIGHT, self.on_move, 'right'), ] accelEntries = [] for binding in bindings: eventId = wx.NewId() accelEntries.append( (binding[0], binding[1], eventId) ) self.Bind(wx.EVT_MENU, lambda event: binding[2](event, binding[3]), id=eventId) accelTable = wx.AcceleratorTable(accelEntries) self.SetAcceleratorTable(accelTable) def on_move(self, e, direction): print direction However, this appears to bind all the accelerators to the last entry, so that Ctrl+Up prints "right", as do all the other three. How to correctly bind multiple handlers in this way?

• Boost Shared Pointers and Memory Management

  - by Izza

  I began using boost rather recently and am impressed by the functionality and APIs provided. In using boost::shared_ptr, when I check the program with Valgrind, I found a considerable number of "Still reachable" memory leaks. As per the documentation of Valgrind, these are not a problem. However, since I used to use the standard C++ library only, I always made sure that any program written is completely free from memory leaks. My question is, are these memory leaks something to worry about? I tried using reset(), however it only decrements the reference count, doesn't deallocate memory. Can I safely ignore these, or any way to forcibly deallocate the memory allocated by boost::shared_ptr? Thank you.

• jquery show hide div's with a href tag

  - by user1736794

  I have some jquery which reveals and hides new div's based on which button is pressed. Rather than buttons i would like to insert my own text/image and have them work in the same way, revealing and hiding the new windows. Here is the jquery: <script> $(document).ready(function(){ $(".buttons").click(function () { var divname= this.value; $("#"+divname).show("slow").siblings().hide("slow"); }); }); </script> Here is the code for one of the buttons which i would like changed to a a href tag. <input type="button" id="button1" class="buttons" value="div1"></input> Any help will be greatly appreciated. Thanks. Pia

• How to write a CASE WHEN statement with multiple DATEDIFF variables

  - by Anne C

  I need to calculate the difference between two dates (facility_start_date, facility_end_date) for a report in Reporting Services in SQL 2005. If the facility_end_date is null then it needs to use the report parameter @EndDate in the calculation. However if the facility_end_date is greater than the parameter @EndDate, then it also needs to use the paramenter @EndDate. The code below works fine except that if the facility_end_date is greater than the parameter @EndDate it is still calculating between the facility_start_date and facility_end_date, rather than between the facility_start_date and @EndDate. Any help would be appreciated. CASE WHEN facility_start_date > facility_end_date THEN NULL WHEN DATEPART(day , facility_start_date) > DATEPART(day , facility_end_date) THEN DATEDIFF(d , facility_start_date , ISNULL(facility_end_date , @EndDate)) - 1 WHEN DATEPART(day , .facility_end_date) > DATEPART(day , @EndDate) THEN DATEDIFF(d , facility_start_date , @EndDate) - 1 ELSE DATEDIFF(d , facility_start_date , ISNULL facility_end_date , @EndDate)) END

• How to build your non-gui Java program into a console program.

  - by Robert

  I dont know how to describe it well, but i will try. Ok, i want to be able to build my java program so that when it opens, it will look and work exactly as it does in the console. So it reads the Scanner class and prints normally, and does everything it would do if it was in the console. Ive looked around for this and havent found anything. I can make a gui java program fairly easily, but i would rather have a terminal, console like program, that works exactly as the java console, thanks.

• Can I have Sinatra / Rack not read the entire request body into memory?

  - by Chris Markle

  Say I have a Sinatra route ala: put '/data' do request.body.read # ... end It appears that the entire request.body is read into memory. Is there a way to consume the body as it comes into the system, rather than having it all buffered in Rack/Sinatra beforehand? I see I can do this to read the body in parts, but the entire body still seems to be read into memory beforehand. put '/data' do while request.body.read(1024) != nil # ... end # ... end

• Problem while compiling the code

  - by Atul

  Can someone points me the problem in the code when compiled with gcc 4.1.0. #define X 10 int main() { double a = 1e-X; return 0; } I am getting error:Exponent has no digits. When i replace X with 10, it works fine. Also i checked with g++ -E command to see the file with preprocessors applied, it has not replaced X with 10. I was under the impression that preprocessor replaces every macro defined in the file with the replacement text with applying any intelligence. Am I wrong? I know this is a really silly question but I am confused and I would rather be silly than confused :). Any comments/suggestions.

• Use jQuery to match variable text?

  - by VUELA

  Hello! I have a sidebar navigation that lists blog entry titles down the side of the page. I am trying to write some jquery that will check the text in the title of the current full blog entry page and match it with the corresponding title in the sidebar navigation so that I can apply a class to style for an active state link ... but I'm not quite getting it! Here is the link to an example page: http://ncw-commercial.com/property-listings/eastpoint-plaza-lot.html, and below is my current code. I have also tried using :contains but could not figure out how to get that to work with a variable rather than direct text. $('.single-journal-entry-wrapper .journal-entry .title').each(function(){ var activeTitle = $(this).text(); $(".feedburnerFeedBlock .headline a").filter(function(index) { return $(this).text() == "activeTitle"; }).parent().addClass("activeTitle"); });

• Can you Borrow a PDF?

  - by WeNeedAnswers

  What are the legalities of letting someone borrow a book that you have purchased that so happens to be in PDF format with no DRM? I know that I can lend a printed book to someone and this not infringe copyright, but a pdf? I know that the thought police are going to be on my case about "no one here is a legal expert" or the "question can't be answered" or "controversial", But I would like to have the opportunity to at least surface the issue, and allow people to comment. I am not looking for point scoring on this, or even an answer, but as stackoverflow has a rather large technical savvy audience that would appreciate the question I think that it could be the next hurdle that will stop technical progress.

• int i vs int index etc. Which one is better?

  - by Earlz

  Coming from a C background I've always used int i for generic loop variables. Of course in big nested loops or other complex things I may use a descriptive name but which one had you rather see? int i; for(i=0;i<Controls.Count;i++){ DoStuff(Controls[i]); } or int index; for(index=0;index<Controls.Count;index++){ DoStuff(Controls[index]); } In the current project I am working on there are both of these styles and index being replaced by ndx. Which one is better? Is the i variable too generic? Also what about the other C style names? i, j, k Should all of these be replaced by actual descriptive variables?

• Permission error while trying to access an (server) program started by a Java program.

  - by Zardoz

  I am starting a server application (normally to be started from the Unix command line) by using Runtime.getRuntime().exec("path/mmserver"). My problem is now that as long as my Java program, which started that server runs, the server is correctly accessible (from command line and other programs). But when my Java program exits the sever is not accessible anymore (the process of the server is still running). I just get such a error message when trying to access the server: "Error: permission_error(flush_output(user_output),write,stream,user_output,errno(32))". The server is a blackbox for me. I am just looking for other ways to start a new process. And maybe someone has a hint why I get that permission error (even if one doesn't know what that server exactly is ... you rather won't know it).

• Is it possible to obtain ASP.NET membership user name after FormsAuth.SignIn ?

  - by Simon_Weaver

  I have some code that is accessing Membership.GetUser() to get the current logged in user. This works fine until I try to access it immediately after logging in with FormsAuth.SignIn(userName, false); However I noticed that neither Membership.GetUser() nor User.Identity.Name is updated with the newly logged in user until a new request (I assume its reading directly from the Request cookies). This however kind of screws up my logic that accesses Membership.GetUser() becasue it introduces a special case. Question: is there a way to read the current logged in user with ASP.NET membership immediately after logging in. Or will I have to introduce my own abstraction layer to allow me to 'set' a user as being logged in ? (This is in an AJAX request - so i'd rather not do a redirect).

• jQuery: Quick question. How to select string variable?

  - by user317563

  Hello world, EDIT: I would like to avoid doing something like this: var str = 'Hello'; if ( str == 'Hello') { alert(str); } I would rather do: var str = 'Hello'; $(str).filter(':contains("Hello")').each(function(){ alert(this) }); I've tried a lot of things: $(str).text().method1().method2().method3(); $(str).val().method1().method2().method3(); $(str).contents().method1().method2().method3(); Nothing worked. Is it possible to do this? Thank you for your time. Kind regards, Marius

• GCC compiler -- bug or unspecified behavior?

  - by Jared P

  When I have conflicting definitions of the ivars of a class in objective-c (not redeclaring the class in the same file, but rather naming the same class with diff ivars, no warnings or better yet errors are issued by the compiler. However, both sets of ivars are useable by the appropriate methods in the respective files. For instance Foo.m: @interface foo { int a; } - (int)method; @end @implementation foo - (int)method { return a; } @end Bar.m: @interface foo { float baz; } @end @implementation foo (category) - (float)blah { return baz; } @end compiles without warnings or errors. Is this intentional? Is this an unchecked error? (for the record, a and baz are actually the same memory location.)

• Learn C++ after learning C#

  - by RichK

  I'm developing a library in C# at the moment and recently bought a great book to help me out but the code snippets are in C++. Does anyone have a link to a site/PDF that'll give me a crash course in C++? (mainly the syntax rather than pros/cons etc) because I'll be developing in C# but things like -, ::, &, **, are giving me the shivers. Obviously the languages aren't 100% compatible but if I know what the C++ is doing from a 'theoretical' point of view I can make a stab at rewriting it in C#. I've had a Google to find the answer but all the sites seem to be "Should I use C++ or C#?", which isn't any good to me. Thanks in advance.

• More HTTP verbs with AS3?

  - by tedw4rd

  I'm developing a social game in Flash with a team of developers. Our server-side guy has developed a really slick RESTful API for the Flash client to talk to. A lot of the client-server interactions involve adding and removing objects from a persistent world, so the API makes extensive use of the PUT and DELETE verbs. The problem is, the URLRequest object in AS3 only supports the GET and POST verbs. We're on a strict schedule, and we'd really rather not have to rewrite the whole API to just use GET and POST. Has anyone come up with a good way to get Flash to send other verbs?

• Google Maps API - load the US

  - by hjk

  I am new to google maps api. I'd like suggestions on achieving the following functionality: whenever the page loads, the map will load centered around the US. Imagine a box around the US with given lat/longs specifying the minimum and maximum boundaries. I need the map to load at the appropriate zoom (and zoom needs to be disabled) such that this box composes the entire map. Basically, I'm wondering if there is a function that loads the map based on lat/long boundaries (or some way to acheive this), rather then loading the map given a zoom level.

• Sharing base object with inheritance

  - by max

  I have class Base. I'd like to extend its functionality in a class Derived. I was planning to write: class Derived(Base): def __init__(self, base_arg1, base_arg2, derived_arg1, derived_arg2): super().__init__(base_arg1, base_arg2) # ... def derived_method1(self): # ... Sometimes I already have a Base instance, and I want to create a Derived instance based on it, i.e., a Derived instance that shares the Base object (doesn't re-create it from scratch). I thought I could write a static method to do that: b = Base(arg1, arg2) # very large object, expensive to create or copy d = Derived.from_base(b, derived_arg1, derived_arg2) # reuses existing b object but it seems impossible. Either I'm missing a way to make this work, or (more likely) I'm missing a very big reason why it can't be allowed to work. Can someone explain which one it is? [Of course, if I used composition rather than inheritance, this would all be easy to do. But I was hoping to avoid the delegation of all the Base methods to Derived through __getattr__.]

• Is PThread a good choice for multi-platorm C/C++ multi-threading program?

  - by RogerV

  Been doing mostly Java and smattering of .NET for last five years and haven't written any significant C or C++ during that time. So have been away from that scene for a while. If I want to write a C or C++ program today that does some multi-threading and is source code portable across Windows, Mac OS X, and Linux/Unix - is PThread a good choice? The C or C++ code won't be doing any GUI, so won't need to worry with any of that. For the Windows platform, I don't want to bring a lot of Unix baggage, though, in terms of unix emulation runtime libraries. Would prefer a PThread API for Windows that is a thin-as-possible wrapper over existing Windows threading APIs. ADDENDUM EDIT: Am leaning toward going with boost:thread - I also want to be able to use C++ try/catch exception handling too. And even though my program will be rather minimal and not particularly OOPish, I like to encapsulate using class and namespace - as opposed to C disembodied functions.

• set the size of the tooltip dialog box depending on the text

  How do i set the size of the tooltip dialog box. the tooltip text must be displayed in one line rather than wrapping the text to other line. in firefox tooltip text is showed in one line but in IE the tooltip text is wrapped . i.e text is displayed in 2 lines. asp:Image runat="server" ID="iUrl" Visible="false" ImageUrl="~/Widgets/FMP_Printers/images/status icons/icon_Fault_Enabled.gif" / if (txtUrl.Text.ToUpper().IndexOf("HTTP://") < 0 && txtUrl.Text.ToUpper().IndexOf("HTTPS://") < 0) { iUrl.Visible = true; iUrl.ToolTip = "ghghghghghghghghghghghghghghghghghghghghghghghghghghghghghghghgh"; valid = false; }

• Tomcat + Struts + OpenID raising ServletExceptions

  - by Rocjoe

  I am working with Tomcat 5.5.x with Struts 1.2 to run a rather large website (large w.r.t. source code). I'm looking to add OpenID to my website, mostly to access attribute exchange to help accelerate the registration process. Every Java implementation for OpenID I have attempted to use will cause a ServletException. Tracing this has been very difficult, but it seems merely instancing any class that makes use of Apache HttpClient will cause the crash. Is this a configuration problem I can address in the JVM, or is it positively wrong to try to initiate an outbound Http request from within an inbound Http request?

• Django: optimizing queries

  - by Josh

  I want to list the number of items for each list. How can I find this number in a single query, rather than a query for each list? Here is a simplified version of my current template code: {% for list in lists %} <li> {{ listname }}: {% with list.num_items as item_count %} {{ item_count }} item{{ item_count|pluralize }} {% endwith %} </li> {% endfor %} lists is passed as: List.objects.filter(user=user) and num_items is a property of the List model: def _get_num_items(self): return self.item_set.filter(archived=False).count() num_items = property(_get_num_items) This queries SELECT COUNT(*) FROM "my_app_item" WHERE... n times, where n is the number of lists. Is it possible to make a single query here?

• 'Caching' a large table in ASP.NET

  - by TheNewGuy

  I understand that each page refresh, especially in 'AjaxLand', causes my back-end/code-behind class to be called from scratch... This is a problem because my class (which is a member object in System.Web.UI.Page) contains A LOT of data that it sources from a database. So now every page refresh in AjaxLand is causing me to making large backend DB calls, rather than just to reuse a class object from memory. Any fix for this? Is this where session variables come into play? Are session variables the only option I have to retain an object in memory that is linked to a single-user and a single-session instance?
