  • Is it OK to put a standard, pure C header #include directive inside a namespace?

    - by mic_e
    I've got a project with a class log in the global namespace (::log). So, naturally, after #include <cmath>, the compiler gives an error message each time I try to instantiate an object of my log class, because <cmath> pollutes the global namespace with lots of three-letter methods, one of them being the logarithm function log(). So there are three possible solutions, each having their unique ugly side-effects. Move the log class to it's own namespace and always access it with it's fully qualified name. I really want to avoid this because the logger should be as convenient as possible to use. Write a mathwrapper.cpp file which is the only file in the project that includes <cmath>, and makes all the required <cmath> functions available through wrappers in a namespace math. I don't want to use this approach because I have to write a wrapper for every single required math function, and it would add additional call penalty (cancelled out partially by the -flto compiler flag) The solution I'm currently considering: Replace #include <cmath> by namespace math { #include "math.h" } and then calculating the logarithm function via math::log(). I have tried it out and it does, indeed, compile, link and run as expected. It does, however, have multiple downsides: It's (obviously) impossible to use <cmath>, because the <cmath> code accesses the functions by their fully qualified names, and it's deprecated to use in C++. I've got a really, really bad feeling about it, like I'm gonna get attacked and eaten alive by raptors. So my question is: Is there any recommendation/convention/etc that forbid putting include directives in namespaces? Could anything go wrong with diferent C standard library implementations (I use glibc), different compilers (I use g++ 4.7, -std=c++11), linking? Have you ever tried doing this? Are there any alternate ways to banish the math functions from the global namespace? I've found several similar questions on stackoverflow, but most were about including other C++ headers, which obviously is a bad idea, and those that weren't made contradictory statements about linking behaviour for C libraries. Also, would it be beneficial to additionally put the #include <math.h> inside extern "C" {}?

  • VB.NET logical expression evaluator

    - by Tim
    I need to test a logical expression held in a string to see if it evaluate to TRUE or FALSE.(the strig is built dynamically) For example the resulting string may contain "'dog'<'cat' OR (14 AND 4<6)". There are no variables in the string, it will logically evaluate. It will only contain simple operators = < < = <= and AND , OR and Open and Close Brackets, string constants and numbers. (converted to correct syntax && || etc.) I currently acheive this by creating a jscipt function and compiling it into a .dll. I then reference the .dll in my VB.NET project. class ExpressionEvaluator { function Evaluate(Expression : String) { return eval(Expression); } } Is there a simpler method using built in .NET functions or Lamdba expressions.

    I added a Twitter Anywhere TweetBox to my blog maxim.tumblr.com like this: var idvar = "tweetbox"; twttr.anywhere(function (T) { T("#tweetbox").tweetBox({ label: "Tweet me:", height: 100, width: 210, defaultContent: "@maxgrinev Hello!", onTweet: function (tweet, htmlTweet) { document.getElementById(idvar).setAttribute("style", "display: none;"); } }); }); Everythink works fine except the tweet button is not active by default. You have to edit the box to make it active (look here: http://maxgrinev.tumblr.com/). How can I make it active by default?

  • What is the most efficient algorithm for reversing a String in Java?

    - by Hultner
    I am wondering which way to reverse a string in Java that is most efficient. Should I use some sort of xor method? The easy way would be to put all the chars in a stack and put them back into a string again but I doubt that's a very efficient way to do it. And please do not tell me to use some built in function in Java. I am interested in learning how to do it not to use an efficient function but not knowing why it's efficient or how it's built up.

Is it something like assigning to a partial function? Why is it done like that?

  • How do you stop a dynamically loaded form from submitting with jquery?

    - by Zak
    I'm working on an AJAX login system. Right now, when the user clicks on a link, the login form is dynamically loaded when the person clicks on a "log in" link. Since I'm using AJAX for this, I want to prevent the form from actually submitting when the submit button is clicked. I tried the following code as part of my load function, and the form loads correctely, but the form still submits normally. $('#loginBox').load('loginform.php'); $('#loginBox form').submit(function(event) { event.preventDefault(); }); How can I fix this?

  • Fluent mapping help

    - by Matt Thrower
    Hi, This is probably a very simple question but I'm new to nHibernate and I'm having trouble working this out. I have a Page object, which can have many Region objects. I also have a Workflow object. Page and Region objects both have a relationship to Workflow and it's this double association that I'm having trouble with. The PageMap has HasMany(Function(x) x.Regions).Cascade.All() And the RegionMap has: References(Function(x) x.Page) And this all seems to work. But how do I define the relationship between Workflow and these two objects?

  • jQuery Mobile focus next input on keypress

    - by user738175
    I have a jquery mobile site with a html form consisting of 4 pin entry input boxes. I want the user to be able to enter a pin in each input field without having to press the iphone keyboards "next" button. I have tried the following and although it appears to set the focus to the second input and insert the value, the keyboard disappears so the user still has to activate the required input with a tap event. $('#txtPin1').keypress(function() { $('#txtPin1').bind('change', function(){ $("#txtPin1").val($("#txtPin1").val()); }); $("#txtPin2").focus(); $("#txtPin2").val('pin2'); }); Is there a different event that I should be assigning to $("#txtPin2")? I have tried to implement http://jqueryminute.com/set-focus-to-the-next-input-field-with-jquery/ this also, but I found that it worked for android and not for iphone. Any help is greatly appreciate it.

  • jqGrid: Is it possible to commit a cell change when tabbing off instead of pressing Enter?

    - by The Matt
    I have a simple in-line edit in my grid, and I want to commit the change when the user tabs off the textbox. The default behavior of jqGrid forces the user to press 'Enter' to commit the change, but this is non-intuitive for our users. onSelectRow: function(id) { $(gridCoreGroups).editRow(id, true, undefined, function(response) { alert("hello world"); } } I've worked my way through the events provided, but they all happen as a result of the user pressing 'Enter', which I want to avoid. Is there something I can wire up that would trigger an action when the user tabs off this cell?

  • Jquery Validation Central Message Many Errors

    - by Iamjon
    Hi everyone, I have a form that is being valdated with the Jquery Validation Plugin. I have managed to get a centeral message "Please Recheck the form", and to have the input focus on the first error. To get this, I had to override the default message of each of the errors. I was wondering if anyone could help me figure out how I can have it display the error message associated with the first error input instead of a general error message. Here is the code: $("#Help-A-Noobie-Form" ).validate({ invalidHandler: function(form, validator) { $(this).find(":input.error:first").focus(); var message = 'Please Recheck The Form' ; $("#Help-A-Noobie-Form #Message p").addClass('red').html(message); }, showErrors: function(errorMap, errorList) { this.defaultShowErrors(); }, rules: { required:true, email: {email:true}, phone: {digits:true} }, messages: { email: "", phone: "", lastname: "", firstname: "", required:"" } })

  • difference in using virtual and not using virtual

    - by numerical25
    In C++, whether you choose to use virtual or not, you can still override the base class function. The following compiles just fine... class Enemy { public: void SelectAnimation(); void RunAI(); void Interact() { cout<<"Hi I am a regular Enemy"; } private: int m_iHitPoints; }; class Boss : public Enemy { public: void Interact() { cout<<"Hi I am a evil Boss"; } }; So my question is what is the difference in using or not using the virtual function. And what is the disadvantage.

  • Calling some functions before main in C

    - by minjang
    I'd like to do some stuffs before main function. I have multiple source files. In each file, there is some work that needs to be done before main. It was no problem in C++, but problematic with C. In C++, this can be done by two ways: Exploiting a constructor of a global class/struct. Calling a function to a global variable For example, static const int __register_dummy_ = __AddRegisterMetaInfo(...); However, in C, either ways is impossible. Obviously, there is no constructor. So, the first option is inherently impossible. I thought that the second option would be possible, but not compiled in C (I tested only with Visual C++. It gives C2099.). C only allows a constant to a non-automatic variable. Is there any way to call some functions before main?

  • asp.net mvc jQuery $.post works but $.get doesn't

    - by iboeno
    Why would POST work but not GET? I'm not using [AcceptVerbs(HttpVerbs.Post)]. I'm calling this: public ActionResult GetTest(string key) { var test = new { HelpTest = key }; return Json(test); } And it works when I do this: $.post("/Home/GetTest", { key: options.key }, function(helpTest) { alert(helpTest.HelpTest); }); But not this: $.get("/Home/GetTest", { key: options.key }, function(helpTest) { alert(helpTest.HelpTest); }); Why would this be? Using GET returns an XMLHttpRequest.status of 500. What am I confused about?

  • PHP: How do I access child properties from a method in a base object?

    - by Nick
    I'd like for all of my objects to be able to return a JSON string of themselves. So I created a base class for all of my objects to extend, with an AsJSON() method: class BaseObject { public function AsJSON() { $JSON=array(); foreach ($this as $key = $value) { if(is_null($value)) continue; $JSON[$key] = $value; } return json_encode($JSON); } } And then extend my child classes from that: class Package extends BaseObject { ... } So in my code, I expect to do this: $Box = new Package; $Box-SetID('123'); $Box-SetName('12x8x6'); $Box-SetBoxX('12'); $Box-SetBoxY('8'); $Box-SetBoxZ('6'); echo $Box-AsJSON(); But the JSON string it returns only contains the BaseClass's properties, not the child properties. How do I modify my AsJSON() function so that $this refers to the child's properties, not the parent's?
