  • How can I call a function at the very end of document.ready

    - by Umair
    I have multiple document.ready functions on a page and I want a function to be called when all my document.ready functions have been executed. I simply want the function to be called at the very end, after all other document.ready functions have executed. An example of this could be that each document.ready function increments a global variable when it has been executed, and the last function needs to check the value of that variable at the very end. Any ideas ?

  • strod() and sprintf() inconsistency under GCC and MSVC

    - by Dmitry Sapelnikov
    I'm working on a cross-platform app for Windows and Mac OS X, and I have a problem with two standard C library functions: strtod() (string-to-double conversion) ? sprintf (when used for outputting double-precision floating point numbers) -- their GCC and MSVC versions return different results. I'm looking for a well-tested cross-platform open-source implementation of those functions, or just for a pair of functions that would correctly and consistently convert double to string and back. I've already tried the clib GCC implementation, but the code is too long and too dependent on other source files, so I expect the adaptation to be difficult. What implementations of string-to-double and double-to-string functions would you recommend?

  • Jquery Clear / reset .Queue() ?

    - by Wes
    I have the following code that triggers two functions whenever a button is clicked. However it only fires the functions once. If i click it again, it does nothing. I need to reset this queue so it fires the functions everytime I click the button. Also, I'm only doing this so I can delay the functions from be fired 1000ms - is there another way to do this? $('#play').click(function() { // other code.. $(this).delay(1000).queue(function(){ countHourly(); countFlights() }); });

  • reference other projects in visual studio for win32 projects

    - by Vineel Kumar Reddy
    Hi All I am working with win32 API and my language of choice is pure C and no C++. Assume I have a project A that is present in Solution S in visual studio I want to add another project B(which has some common utility functions) in to S Now I want to reference Project B in Project A... So that I can use those utility functions from Project B source code level. I dont want it be used against dll of Project B assume project B contains some math related functions and i want to call the functions from Project A or project B contains come data structures and i want to make use of them in Project A How to achieve this.... thanks in advance

  • Frustration with generics

    - by sbi
    I have a bunch of functions which are currently overloaded to operate on int and string: bool foo(int); bool foo(string); bool bar(int); bool bar(string); void baz(int p); void baz(string p); I then have a bunch of functions taking 1, 2, 3, or 4 arguments of either int or string, which call the aforementioned functions: void g(int p1) { if(foo(p1)) baz(p1); } void g(string p1) { if(foo(p1)) baz(p1); } void g(int p2, int p2) { if(foo(p1)) baz(p1); if(bar(p2)) baz(p2); } void g(int p2, string p2) { if(foo(p1)) baz(p1); if(bar(p2)) baz(p2); } void g(string p2, int p2) { if(foo(p1)) baz(p1); if(bar(p2)) baz(p2); } void g(string p2, string p2) { if(foo(p1)) baz(p1); if(bar(p2)) baz(p2); } // etc. (The implementation of the g() family is just a placeholder. actually they are more complicated.) More types than the current int or string might have to be introduced at any time. The same goes for functions with more arguments than 4. The current number of identical functions is barely manageable. Add one more variant in either dimension and the combinatoric explosion will be so huge, it might blow away the application. In C++, I'd templatize g() and be done. I understand that .NET generics are different. <sigh> But I have been fighting them for two hours trying to come up with a solution that doesn't involve too much copy&paste of code. To no avail. Surely, C#/.NET/generics/whatever won't require me to type out identical code for a family of functions taking five arguments of either of three types? So what am I missing here?

  • Does changing the order of class private data members breaks ABI

    - by Dmitry Yudakov
    I have a class with number of private data members (some of them static), accessed by virtual and non-virtual member functions. There's no inline functions and no friend classes. class A { int number; string str; static const int static_const_number; public: // got virtual and non-virtual functions, working with these memebers virtual void func1(); void func2(); // no inline functions or friends }; Does changing the order of private data members breaks ABI in this case? class A { string str; static const int static_const_number; int number; // <-- integer member moved here ... };

  • Conditional macro expansion

    - by Dave DeLong
    Heads up: This is a weird question. I've got some really useful macros that I like to use to simplify some logging. For example I can do Log(@"My message with arguments: %@, %@, %@", @"arg1", @"arg2", @"arg3"), and that will get expanded into a more complex method invocation that includes things like self, _cmd, __FILE__, __LINE__, etc, so that I can easily track where things are getting logged. This works great. Now I'd like to expand my macros to not only work with Objective-C methods, but general C functions. The problem is the self and _cmd portions that are in the macro expansion. These two parameters don't exist in C functions. Ideally, I'd like to be able to use this same set of macros within C functions, but I'm running into problems. When I use (for example) my Log() macro, I get compiler warnings about self and _cmd being undeclared (which makes total sense). My first thought was to do something like the following (in my macro): if (thisFunctionIsACFunction) { DoLogging(nil, nil, format, ##__VA_ARGS__); } else { DoLogging(self, _cmd, format, ##__VA_ARGS__); } This still produces compiler warnings, since the entire if() statement is substituted in place of the macro, resulting in errors with the self and _cmd keywords (even though they will never be executed during function execution). My next thought was to do something like this (in my macro): if (thisFunctionIsACFunction) { #define SELF nil #define CMD nil } else { #define SELF self #define CMD _cmd } DoLogging(SELF, CMD, format, ##__VA_ARGS__); That doesn't work, unfortunately. I get "error: '#' is not followed by a macro parameter" on my first #define. My other thought was to create a second set of macros, specifically for use in C functions. This reeks of a bad code smell, and I really don't want to do this. Is there some way I can use the same set of macros from within both Objective-C methods and C functions, and only reference self and _cmd if the macro is in an Objective-C method?

  • Managing multiple AJAX calls to PHP scripts

    - by relativelycoded
    I have a set of 5 HTML dropdowns that act as filters for narrowing results returned from a mySQL database. The three pertinent filters are for "Province", "Region", and "City" selection, respectively. I have three functions: findSchools(), which runs when any of the filters (marked with CSS class .filter) are changed, and fetches the results via AJAX from a PHP script. Once that is done, two other functions are called... changeRegionOptions(), which, upon changing the "Province" filter, and updates the available options using the same method as the first function, but posting to a different script. changeCityOptions(), which runs if the "Region" filter was changed, and updates options, again using the same method. The problem is that since I want these AJAX functions to run simultaneously, and they by nature run asynchronously, I've tried using $.when to control the execution of the functions, but it doesn't fix the problem. The functions run, but the Region and City filters return blank (no options); the FireBug report shows absolutely no output, even though the POST request went through. The posted parameter for filter_province gets sent normally, but the one for region gets cut off at the end -- it sends as filter_region=, with no value passed. So I'm presuming my logic is wrong somewhere. The code is below: // When any of the filters are changed, let's query the database... $("select.filter").change(function() { findSchools(); }); // First, we see if there are any results... function findSchools() { var sch_province = document.filterform.filter_province.value; var sch_region = document.filterform.filter_region.value; var sch_city = document.filterform.filter_city.value; var sch_cat = document.filterform.filter_category.value; var sch_type = document.filterform.filter_type.value; $.post("fetch_results.php", { filter_province : sch_province, filter_region : sch_region, filter_city : sch_city, filter_category : sch_cat, filter_type : sch_type }, function(data) { $("#results").html(""); $("#results").hide(); $("#results").html(data); $("#results").fadeIn(600); } ); // Once the results are fetched, we want to see if the filter they changed was the one for Province, and if so, update the Region and City options to match that selection... $("#filter_province").change(function() { $.when(findSchools()) .done(changeRegionOptions()); $.when(changeRegionOptions()) .done(changeCityOptions()); }); }; This is just one of the ways I've tried to solve it; I've tried using an IF statement, and tried calling the functions directly inside the general select.filter.change() function (after findSchools(); ), but they all return the same result. Any help with this would be great!

  • Stored Procedure in Entity Framework

    - by kamal
    Hi I had added the Stored procedure in my Entity framework and i also imported the functions in the edmx. Is it must to add all the three functions insert, update, and delete functions to a table. I had tried with insert alone and also with all, but why can't i get the name of the stored procedure in the connection string. Let me know what i done clearly. I had added the sp i had imported the functions in the model browser. i had also mapped the insert, update and delete function to the table with return type only for insert and update. Still i can't get the name of SP in the connection string. Please let me know how could i resolve this issue. Thanks in Advance, Kamal.

  • AS3: Adding get/set methods to a class via prototype

    - by LiraNuna
    I'm looking for a way to extend a class via prototype by adding a get and set functions. The following code will add a function to the class' prototype: MyClass.prototype.newMethod = function(... args) { }; However I want to add both a get and set functions. I tried: MyClass.prototype.fakeProperty = get function(... args) { }; MyClass.prototype.fakeProperty = set function(... args) { }; But that seem to throw compile errors. Is this even possible? Is there some 'internal' naming convention for get/set functions? I am not looking for answers such as 'create a new class and new get/set functions there'.

  • Looking for a good Delphi unicode string library

    - by volvox
    Any suggestion for a good unicode string library for Delphi 2010? Such thing as class that would contain a collection of independent functions, basically an encapsulation of functions that manipulate strings (ex: Trimlike, Character removal, Positional, Sub-string, Compare, Informational, Case, Replacement, Manipulation functions etc. ). Thanks

  • Endianness manipulation - is there a C library for this?

    - by Malvineous
    Hi all, With the sort of programs I write (working with raw file data) I often need functions to convert between big and little endian. Usually I write these myself (which is covered by many other posts here) but I'm not that keen on doing this for a number of reasons - the main one being lack of testing. I don't really want to spend ages testing my code in a big endian emulator, and often just omit the code for big endian machines altogether. I also would rather make use of faster functions provided by various compilers, while still keeping my programs cross-platform. The only things I can find are socket calls like htons() but they require different #include files on each platform, and some GPL code like this, however that particular file, while comprehensive, seems to miss out on some of the high performance functions provided by some compilers. So, does anyone know of a library (ideally just a .h file) that is well tested and provides a standard set of functions for dealing with endianness across many compilers and platforms?

  • Is there a .def file equivalent on Linux for controlling exported function names in a shared library

    - by morpheous
    I am building a shared library on Ubuntu 9.10. I want to export only a subset of my functions from the library. On the Windows platform, this would be done using a module definition (.def) file which would contain a list of the external and internal names of the functions exported from the library. I have the following questions: How can I restrict the exported functions of a shared library to those I want (i.e. a .def file equivalent) Using .def files as an example, you can give a function an external name that is different from its internal name (useful for prevent name collisions and also redecorating mangled names etc) On windows I can use the EXPORT command (IIRC) to check the list of exported functions and addresses, what is the equivalent way to do this on Linux?

  • Executing a dynamically bound function in Clojure

    - by Carl Smotricz
    I'd like to pre-store a bunch of function calls in a data structure and later evaluate/execute them from within another function. This works as planned for functions defined at namespace level with defn (even though the function definition comes after my creation of the data structure) but will not work with functions defined by let [name (fn or letfn inside the function. Here's my small self-contained example: (def todoA '(funcA)) (def todoB '(funcB)) (def todoC '(funcC)) (def todoD '(funcD)) ; unused (defn funcA [] (println "hello funcA!")) (declare funcB funcC) (defn runit [] (let [funcB (fn [] (println "hello funcB"))] (letfn [(funcC [] (println "hello funcC!"))] (funcA) (eval todoA) ; OK (funcB) ; OK (eval todoB) ; "Unable to resolve symbol: funcB in this context" at line 2 (funcC) ; OK (eval todoC) ; "Unable to resolve symbol: funcC in this context" at line 3 ))) Is there a simple fix I could undertake to get eval'd quoted calls to functions to work for functions defined inside another function?

  • Integration of C#, F#, IronPython and IronRuby

    - by prosseek
    I was told that the assembly files made from C# and F# source is interoperable as they are compiled into .NET assembly. Q1 : Does that mean that C# can call F# functions just like they are C# functions? Q2 : How about the IronPython and IronRuby? I don't see any assembly dll from the IronPython/IronRuby. Q3 : Is there any easy way to use IronPython/IronRuby functions from C# or F#?

  • Generation of .tlb Files in Windows 7 Pro 32-bit

    - by aF
    I have a C++ DLL that imports a .tlb file generated in a C# project. The C++ DLL is a wrapper DLL containing functions that call the corresponding C# functions. When I call the C++ functions on the computer that I built the projects, all works well. But when I copy the DLL's and generated tlb's to another computer with the same exact version of Windows and installed programs andI call the C++ functions, it breaks with a COM error. However, after recompiling the projects on the new computer, everything works again. I already checked the "Work on All Computers" for both projects but this keeps happening. What else do I need to do for the DLL's to work on all computers?

  • What is the merit of the "function" type (not "pointer to function")

    - by anatolyg
    Reading the C++ Standard, i see that there are "function" types and "pointer to function" types: typedef int func(int); // function typedef int (*pfunc)(int); // pointer to function typedef func* pfunc; // same as above I have never seen the function types used outside of examples (or maybe i didn't recognize their usage?). Some examples: func increase, decrease; // declares two functions int increase(int), decrease(int); // same as above int increase(int x) {return x + 1;} // cannot use the typedef when defining functions int decrease(int x) {return x - 1;} // cannot use the typedef when defining functions struct mystruct { func add, subtract, multiply; // declares three member functions int member; }; int mystruct::add(int x) {return x + member;} // cannot use the typedef int mystruct::subtract(int x) {return x - member;} int main() { func k; // the syntax is correct but the variable k is useless! mystruct myobject; myobject.member = 4; cout << increase(5) << ' ' << decrease(5) << '\n'; // outputs 6 and 4 cout << myobject.add(5) << ' ' << myobject.subtract(5) << '\n'; // 9 and 1 } Seeing that the function types support syntax that doesn't appear in C (declaring member functions), i guess they are not just a part of C baggage that C++ has to support for backward compatibility. So is there any use for function types, other than demonstrating some funky syntax?

  • CakePHP: Interaction between different files/classes

    - by Alexx Hardt
    Hey, I'm cloning a commercial student management system. Students use the frontend to apply for lectures, uni staff can modify events (time, room, etc). The core of the app will be the algortihm which distributes the seats to students. I already asked about it here: How to implement a seat distribution algorithm for uni lectures Now, I found a class for that algorithm here: http://www.phpclasses.org/browse/file/10779.html I put the 'class GA' into app/vendors. I need to write a 'class Solution', which represents one object (a child, and later a parent for the evolutionary process). I'll also have to write functions mutate(), crossover() and fitness(). fitness calculates a score of a solution, based on if there are overbooked courses etc; crossover() is the crazy monkey sex function which produces a child from two parents, and mutate() modifies a child after crossover. Now, the fitness()-function needs to access a few related models, and their find()-functions. It evaluates a solution's fitness by checking e.g. if there are overbooked courses, or unfulfilled wishes, and penalizes that. Where would I put the ga.php, solution.php and the three functions? ga.php has to access the functions, but the functions have to access the models. I also don't want to call any App::import()'s from within the fitness()-function, because it gets called many thousand times when the algorithm runs. Hope someone can help me. Thanks in advance =)

  • How can I call an Actionscript function when the .swf is referenced by jQuery?

    - by Arms
    I have an .swf that I am embedding into HTML using the jQuery SWF Object plugin (http://jquery.thewikies.com/swfobject). I have a number of functions within the .swf that I need to call from within javascript functions. I've made these actionscript functions accessible to javascript by calling flash.external.ExternalInterface.addCallback(). Yet nothing happens when I make the call. I've had this happen before and it seems to be that when you reference the .swf from jQuery, you can't call flash functions. Is there anyway around this (aside from not using jQuery)? Thanks.

  • Interpreter in C++: Function table storage problem

    - by sub
    In my interpreter I have built-in functions available in the language like print exit input, etc. These functions can obviously be accessed from inside the language. The interpreter then looks for the corresponding function with the right name in a vector and calls it via a pointer stored with its name. So I gather all these functions in files like io.cpp, string.cpp, arithmetic.cpp. But I have to add every function to the function list in the interpreter in order for it to be found. So in these function files I have things like: void print( arg ) { cout << arg.ToString; } I'd add this print function to the interpreter function list with: interpreter.AddFunc( "print", print ); But where should I call the interpreter.AddFunc? I can't just put it there below the print function as it has to be in a function according to the C++ syntax. Where and how should all the functions be added to the list?
