  • beneficial in terms of performance

    Hi, is it better to declare Webservice class object instances as static as the .asmx webservice classes have only static methods. what i want is that i declare and instantiate webservice asmx class as static in aspx Page Behind Class. and on every event call on that page i could perform operation against webservice methods. is it beneficial in terms of performance? Thanks Usama

  • Tcl question - how to list functions in a namespace

    - by Bub Bradlee
    I am trying to list all of the functions a namespace has in it (warning - I'm really new to Tcl, so I'll probably use the wrong words for parts of Tcl). For example, I have a tcl shell someone compiled for me (if that's the right way to phrase it), and I know at least one function exists, let's call it blah::do_something I know in ruby there are ways to list all the functions in a module/namespace. How would I find out what other functions are available in the blah namespace in Tcl? Thanks in advance

  • Can I rename Main.mxml?

    - by Randyaa
    We have several Flash objects included in our project. We call each one a specific type of widget... For readability/debugging purposes I'd like to rename Main.mxml to something else. At first this seemed easy, as it would be just a setting in our maven configuration (we're using flex mojos to build our swf). However; changing the sourceFile from Main.mxml to MyWidget.mxml doesn't seem to do it. Any thoughts?

  • SQL Compact - Hang on invalid file

    - by eWolf
    I use Linq to Sql Compact with code generated by sqlmetal. When I open an invalid database, like eg an mp3, I can create the DataContext without getting an Exception. But when I query any data or call DatabaseExists, the application hangs. Why is no exception thrown? Is this a known problem?

  • Some clarification on rvalue references

    - by Dennis Zickefoose
    First: where are std::move and std::forward defined? I know what they do, but I can't find proof that any standard header is required to include them. In gcc44 sometimes std::move is available, and sometimes its not, so a definitive include directive would be useful. When implementing move semantics, the source is presumably left in an undefined state. Should this state necessarily be a valid state for the object? Obviously, you need to be able to call the object's destructor, and be able to assign to it by whatever means the class exposes. But should other operations be valid? I suppose what I'm asking is, if your class guarantees certain invariants, should you strive to enforce those invariants when the user has said they don't care about them anymore? Next: when you don't care about move semantics, are there any limitations that would cause a non-const reference to be preferred over an rvalue reference when dealing with function parameters? void function(T&); over void function(T&&); From a caller's perspective, being able to pass functions temporary values is occasionally useful, so it seems as though one should grant that option whenever it is feasible to do so. And rvalue references are themselves lvalues, so you can't inadvertently call a move-constructor instead of a copy-constructor, or something like that. I don't see a downside, but I'm sure there is one. Which brings me to my final question. You still can not bind temporaries to non-const references. But you can bind them to non-const rvalue references. And you can then pass along that reference as a non-const reference in another function. void function1(int& r) { r++; } void function2(int&& r) { function1(r); } int main() { function1(5); //bad function2(5); //good } Besides the fact that it doesn't do anything, is there anything wrong with that code? My gut says of course not, since changing rvalue references is kind of the whole point to their existence. And if the passed value is legitimately const, the compiler will catch it and yell at you. But by all appearances, this is a runaround of a mechanism that was presumably put in place for a reason, so I'd just like confirmation that I'm not doing anything foolish.

  • Security-Active Application in background-Does it store image of current screen

    - by user1509593
    Is this a probable security flaw. A user in public (lets say Starbucks) tries to log in to iOS application. He enters user id and password [Password is hidden using xxxxxxxx (not exposed)] and a call comes in or he presses home and the application goes to background. a) Does iOS store an image of current screen b) A malicious hacker with intent takes control of the device. Can he read the password ? Do we have to clear out sensitive information while going to background

    - by Incognito
    I have an application which intensively uses DB (SQL Server). As it must have high performance I would like to know the fastest way to insert record into DB.Fastest from the standpoint of execution time. What should I use ? As I know the fastest way is to create stored procedure and to call it from code (ADO.NET). Please let me know is there any better way or may be there are is some other practices to increase performance.

    I'm trying to call a webservice with Soap in PHP5, for this, I need to use WS-Security 1.1. (In java and .NET this is all generated automatically.) Are there any frameworks available to generate the security headers easily in PHP? Or do I have to add the entire header myself ?

  • How is thread local storage (__thread) implemented on LInux?

    - by anon
    __thread Foo foo; How is "foo" actually resolved? Does the compiler silently replace every instance of "foo" with a function call? Is "foo" stored somewhere relative to the bottom of the stack, and the compiler stores this as "hey, for each thread, have this space near the bottom of the stack, and foo is stored as "offset x from bottom of stack"" ? Insights please.

    I have a worker thread in a class that is owned by a ChildView. (I intend to move this to the Doc eventually.) When the worker thread completes a task I want all the views to be updated.

  • ASP.NET LINQ to SQL SubmitChanges() doesn't update the database

    - by Alex
    In my 2nd ASP.NET MVC project I'm facing a very weird problem: when I call the SubmitChanges method of the DataContext class, nothing updates in the database. It's weird because everything works fine with my first project. I'm using a remote database created in Sql Server Management Studio, I tried doing some queries there and in Visual Studio 2010 (where I have the connection to the database), they all work. Where might the problem be hidden?

  • Use OpenOffice to do server-side ppt(x) to swf conversion

    - by Steven Xu
    I'd like to turn Powerpoint presentations to SWF files the same way that OpenOffice does it, except automatically through a command line call. I came across http://stackoverflow.com/questions/886144, which led me to explore PyUNO bridge, which comes with OpenOffice as well as the OpenOffice command line API, but I wasn't able to make anything productive of it. Any guidance is appreciated. If there is a good solution outside of OpenOffice, I would be happy to try it too.

  • Using jQuery's ajax get request with parameters, returning page content

    - by Stevie Jenowski
    Thank you for looking at my question, as I appreciate your time. Okay, so I'm trying to use jQuery's get function to call my php script which ultimately returns a variable which is a built template of the main content of my page minus my static header/footer, for which I would like to replace the "old" page content without the page reloading. Can anyone point me in the right direction as to where I'm going wrong here? My code is as follows... jQuery: function getData(time, type) { $.ajax({ type: "GET", url: "getData.php", data: "time=" + time + "&type=" + type, success: function(data){ $('#pageContent').fadeOut("slow"); $('#pageContent').html(data); $('#pageContent').fadeIn("slow"); } }); return false; } getData.php(paraphrased): .... $time = empty($_GET['time']) ? '' : $_GET['time']; $type = empty($_GET['type']) ? '' : $_GET['type']; echo getData($time, $type); function getData($time, $type) ...... ..... $tmpl = new Template(); $tmpl->time= $time; $tmpl->type = $type; $builtpage = $tmpl->build('index.tmpl'); return $builtpage; ..... ...... jQuery function call: <a href="#" onclick="getData("<?php print $tmpl->time; ?>", "Orange")">Orange</a> <a href="#" onclick="getData("<?php print $tmpl->time; ?>", "Apple")">Apple</a> <a href="#" onclick="getData("<?php print $tmpl->time; ?>", "Banana")">Banana</a> When I click any link, the ajax seems to run fine, and the page does refuse to reload, but the content still remains unchanged... Anyone happen to know what's up?
