  • Eclipse, Android ndk, source files, and library project dependencies

    - by Android Noob
    In Microsoft Visual Studio 2010, it is possible to create a Solution with multiple projects and set dependencies between projects. I'm trying to figure out if the same thing can be done using Eclipse via the NDK. More specifically, I want to know if it is possible to create C source files in an ordinary Android project that can reference C header files in an Android library project. For example: Android library project: Sockets Ordinary Android project: Socket_Server Sockets contains all the C header/source files that are needed to do socket I/O. Socket_Server contains test code that makes calls to the functions that are defined in Sockets library project. This test code requires a header file that contains the function declaration of all API calls. I already set the library dependencies between the projects via: Properties > Android > Library > Add

  • Using Jquery, call function on selection just once

    - by maxp
    Say i have a selection of textboxes like this; var arrayoftextboxes = $('.textbox1, .textbox2, .textbox3'); Is there a way I can call a function on each one in a simpler way than this? It only needs to be called once. arrayoftextboxes.each(function(i){foo(arrayoftextboxes[i]);}); I tried arrayoftextboxes.load(function(){foo(this)}); and arrayoftextboxes.bind(function(){foo(this)}); but the functions dont seem to be called.

  • jQuery Click event on object added with JavaScript not working.

    - by Hultner
    I'm work on a quiz for school but I've bumped into a problem. I got a javascript file for custom radio buttons (CUSTOM FORM ELEMNTS by Ryan Fait if it's helping). The script hides the input buttons and adds custom styled spans instead. Now what I want, when I click one of these JavaScript added spans I want to remove disabled for a button called "Next Question" which when pressed takes you to the next question. The reason for this is that I don't want people to accidently got to the next question without choosing a answer. The problem is when I press the added spans nothing happens but when I press another identical span which I have added in the html it works just as intended. The span got the class radio which is the class I'm looking for in the jQuery. Here's the test page with the error on: http://hultner.se/graphicsquiz/livetest/livetest.php Short: Can't get jQuery .click() functions to work with spans added using JavaScript earlier in the document.

  • How to modify the HTML and BODY tags in an ASP.NET page without adding runat=server to the elements?

    - by jon333
    In an ASP.NET web forms project that is not quite ready to be upgraded from 2.0 to 4.0 , there is a change that needs to be made to allow modifications to the HTML and BODY tags on the pages without adding runat=server to the tags which results in the 2.0 styled "ugly ids" like "ctrl_100..." For example, how could we change these using JavaScript, a Response Filter (the regex to find these specific tags would really help on this one), or something else...from: <html xmlns="//www.w3.org/1999/xhtml"> <body> To: <html lang="jp=JP" xmlns="//www.w3.org/1999/xhtml" dir="rtl"> <body dir="rtl"> JavaScript seems like a possibility, but functions from the server-side could would determine the language and direction the page should have.

  • JSObject-like stuff in ActionScript 3?

    - by johncch
    I would like to ask if there is a liveconnect equivalent for ActionScript 3. I understand that there is the ExternalInterface class inside AS3 but it only supports calling a method by name. The really cool thing about Java and LiveConnect is that you can do something like function jsFunc(name) = { this.name = name; this.talk = function(){ alert('hello world my name is ' + this.name); } } javaapplet.function(new jsFunc("bob")); The above approaches pseudo code since I never tested it but I've seen it in action. In AS3, while I am able to pass in an instance of JavaScript "object" into AS, it is often converted into an ActionScript Object instance which does away with all the functions as far as I'm aware. I saw an implementation of JSInterface but I don't think it does specifically that. Is there any way to make OO like javascript work with ActionScript 3?

  • Why would ftp_connect() return false on production server if it works elsewhere for connecting to th

    - by letseatfood
    I have a script that uses ftp_connect() among other FTP PHP functions for uploading a file. ftp_connect() works when executed on my local development server for connecting to a remote FTP server. The same script, when executed on the remote server does not work for connecting to the exact same FTP server. Could somebody please point me in the right direction? Thanks! Here is the code: error_reporting(E_ERROR | E_WARNING | E_PARSE); $server = 'ftp.someserver.com'; $ftpConn = ftp_connect($server); if(!$ftpConn) echo 'failed'; else echo 'success'; No errors are reported.

  • How to solve this problem with lists?

    - by osabri
    what i don't understand in my task here what kind of list i can use, and if it should have 2 attributes key and value ? or only value? with pointers to another node ofc the task: "design a function which create a list using input from the keyboard _ the prefered solution. Assume that some magic stops the input; so the length of a list is not known in advance.(alternative solution: a function which creates explicitly a fixed list. However, all other function can not assume any knowledge about the length of lists). Necessary utilities( additional functions to be created): a function which deallocates the memory used for lists and a function which prints the content of the list. let the element of lists contain a letter. Design a function which create a copy of such list. can't also understand the list line !!!!!???

  • How do I dynamically load a js file using Prototype?

    - by domagoj412
    Hello, I am using prototype to load external js file (actually it is php file) dynamically. Like this: function UpdateJS(file) { var url = 'main_js.php?file='+file; var myAjax = new Ajax.Request( url, {method: 'get', onComplete: showResponseHeader} ); } function showResponseHeader (originalRequest) { $('jscode').innerHTML = originalRequest.responseText; } Container "jscode" is defined like this: <script type="text/javascript" id="jscode"></script> And it works! But if some different file is called, all the functions from previous one are preserved. And I don't want that. Anybody knows how to "unload" first js file when second one is called? (I also tried using Ajax.Updater function but the result is the same.) Update: It turns out that there is bigger problem: it only loads if function "UpdateJS" is in window.onload that is why it doesn't load anything else after that. So prototypes update it's maybe not such a good way for this...

  • Use one single DLL library to import other libraries at runtime

    - by Yifan
    I am writing a Win32 DLL library that can be redistributed. I am using different versions of the windows API because I want to support Windows 7 functions, but still have support for Windows 2000 (with some function disabled). What I have currently is MyLib2000.dll, MyLibXP.dll, and MyLibVista.dll, and my application chooses which library to load at runtime. I want a way to have a single DLL (MyLib.dll) that stores the other three in itself and when it's being loaded, it extracts the correct DLL out of itself and loads it. I know this is not the best way to do this, so suggestions on another method of doing this is welcome.

  • Legality Of Re-Implementing An Existing API (e.g. GNU implementing the UNIX APIs)

    - by splicer
    I've often wondered about this. I'm not looking for legal advice, just casual opinions ;) If some company publishes an API on the web for their closed-source library, would it be legal for another party to release an open-source implementation of that API? Are function declarations considered source code? Take GNU implementing the UNIX APIs, for example. The UNIX standard gives the following function declaration and defines its required behaviour in English: char * mktemp(char *template); Now, consider an API that lists and declares and describes several thousand (more much complex) functions, enums, etc.; an API which defines a solution to a non-trival set of problems. If an open-source project publishes C headers that copy (verbatim) the function definitions contained in the closed-source company's published API, doesn't that violate some sort copyright law?

  • Display fraction with numerator/denominator with empty fields for users to enter text

    - by Anil
    Hi all I have a scenario in which I need to design online keyboard with buttons implementing different mathematical functions in ASP.NET. For example 1) A button called "Fraction" Onclicking= should display A numerator and a denominator separated by '-' with empty fields. Just as we write fractions manually. Now when the user clicks on this button the cursor should focus on numerator displaying 'the division line' and then by pressing 'Down' arrow key(on computr keyboard) should focus on denominator allowing users to enter both fields. Keeping it simple the user should be able to toggle between numerator and denominator. Please help me with some sample code. I have got no idea. Thanks in advance

  • How do I write a scheme macro that defines a variable and also gets the name of that variable as a s

    - by Jason Baker
    This is mostly a follow-up to this question. I decided to just keep YAGNI in mind and created a global variable (libpython). I set it to #f initially, then set! it when init is called. I added a function that should handle checking if that value has been initialized: (define (get-cpyfunc name type) (lambda args (if libpython (apply (get-ffi-obj name libpython type) args) (error "Call init before using any Python C functions")))) So now here's what I want to do. I want to define a macro that will take the following: (define-cpyfunc Py_Initialize (_fun -> _void)) And convert it into this: (define Py_Initialize (get-cpyfunc "Py_Initialize" (_fun -> _void))) I've been reading through the macro documentation to try figuring this out, but I can't seem to figure out a way to make it work. Can anyone help me with this (or at least give me a general idea of what the macro would look like)? Or is there a way to do this without macros?

  • Double indirection and structures passed into a function

    - by ZPS
    I am curious why this code works: typedef struct test_struct { int id; } test_struct; void test_func(test_struct ** my_struct) { test_struct my_test_struct; my_test_struct.id=267; *my_struct = &my_test_struct; } int main () { test_struct * main_struct; test_func(&main_struct); printf("%d\n",main_struct->id); } This works, but pointing to the memory address of a functions local variable is a big no-no, right? But if i used a structure pointer and malloc, that would be the correct way, right? void test_func(test_struct ** my_struct) { test_struct *my_test_struct; my_test_struct = malloc(sizeof(test_struct)); my_test_struct->id=267; *my_struct = my_test_struct; } int main () { test_struct * main_struct; test_func(&main_struct); printf("%d\n",main_struct->id); }

  • two HashMap iteration

    - by user431276
    I have two HashMaps and I can iterate both hashmaps with following code Iterator it = mp.entrySet().iterator(); while (it.hasNext()) { Map.Entry pairs = (Map.Entry)it.next(); String firstVal = pairs.getValue(); } Iterator it2 = mp2.entrySet().iterator(); while (it2.hasNext()) { Map.Entry pairs2 = (Map.Entry)it.next(); String SecondVal = pairs2.getValue(); } myFunction(firstVal, SecondVal) Is there anyway to iterate two hashmaps at the same time without using two loops? Currently, I have a method that accepts two parameters and each parameter value is stored in first and second hashmap. I have to iterate first hash then second to get values. I think there must be a good way to do it but I don't know :( P.S: there could be some errors in above code as this is just an example to explain my problem. Each iterator is a method in original program and accept one parameter. I couldn't copy past real time functions as they are HUGE !

  • Can you make a PHP function recursive without repeating it's name?

    - by alex
    It's always bugged me a recursive function needs to name itself, when a instantiated class can use $this and a static method can use self etc. Is there a similar way to do this in a recursive function without naming it again (just to cut down on maintenance)? Obviously I could use call_user_func or the __FUNCTION__ constant but I would prefer something less ugly. Update Thanks for your answers. I might stick to including the function name for simple functions, and make take the other approaches for anything more complicated.

  • Creating a PHP call home "time bomb" to protect my interests

    - by RC
    Hi everyone, I produced a PHP web app for a client some months back that is hosted on their own server. I have still not been paid for this work, and they are giving me the runaround. It turns out that I still have remote admin access to their server, so I can make code changes. What I was thinking of doing was to move the core kernel off-site onto one of my own servers, and program in some kind of callback or include that gets the kernel (critical functions) from my server. Give it two weeks or so for their backups to catch this change, and then pull the plug and exercise leverage. If I do this, they will pay immediately, because the site is a critical one for a very large and influential client of theirs. What is the most effective and easiest way of doing this? What code do I use? Thanks for any pointers.

  • External GUI/Helper Library for Visual C++?

    - by Psychic
    I am looking for some kind of library, either open source or bought in, that provides advanced GUI components, helper functions & classes etc. It needs to be something that integrates relatively easily into Visual Studio, and should be based around C++ and Windows. Cross platform isn't needed, and can somtimes make things a little more complex and restricted than single platform, but it is still acceptable. It also needs to be up-to-date and active. There appears to be a number of 'retired' libraries that offer little or no support, so these would not be suitable, as I'm going to need help every now and then! It also needs good documentation. I know about wxWidgets but I'm wondering what other alternatives there are? At first glance, wxWidgets doesn't strike me as what I want/need, especially in the GUI area where the visual components seem striking similar to the stock components. I want more custimization! Is there much out there that meets these requirements?

  • How to declare a function that accepts a lambda?

    - by Andreas Bonini
    I read on the internet many tutorials that explained how to use lambdas with the standard library (such as std::find), and they all were very interesting, but I couldn't find any that explained how I can use a lambda for my own functions. For example: int main() { int test = 5; LambdaTest([&](int a) { test += a; }); return EXIT_SUCCESS; } How should I declare LambdaTest? What's the type of its first argument? And then, how can I call the anonymous function passing to it - for example - "10" as its argument?

  • Setting ID to a control inside repeater itemtemplate

    - by toraan
    Inside repeater's itemtemplate I have a Panel server control. I need to assign special Id for it, because I need to work with some javascript functions that use this Id. In repeater ItemDataBound event I have this: pnlButtonsPanel.ID = pnlButtonsPanel.ID + DataBinder.Eval(e.Item.DataItem, "ID"); But this solution is not good because after a postback the page is re -rendered and I lose the new ID. (And I don't want to rebind repeater after every postback) I tried to set the ID on aspx page like that: <asp:Panel id='<%# Eval("ID") %>' and some other variations but always get compile errors.

  • Ways not to write function headers twice?

    - by mee
    Hi, I've got a C/C++ question, can I reuse functions across different object files or projects without writing the function headers twice? (one for defining the function and one for declaring it) I don't know much about C/C++, Delphi and D. I assume that in Delphi or D, you would just write once what arguments a function takes and then you can use the function across diferent projects. And in C you need the function declaration in header files *again??, right?. Is there a good tool that will create header files from C sources? I've got one, but it's not preprocessor-aware and not very strict. And I've had some macro technique that worked rather bad. I'm looking for ways to program in C/C++ like described here http://www.digitalmars.com/d/1.0/pretod.html

  • Threaded Django task doesn't automatically handle transactions or db connections?

    - by Gabriel Hurley
    I've got Django set up to run some recurring tasks in their own threads, and I noticed that they were always leaving behind unfinished database connection processes (pgsql "Idle In Transaction"). I looked through the Postgres logs and found that the transactions weren't being completed (no ROLLBACK). I tried using the various transaction decorators on my functions, no luck. I switched to manual transaction management and did the rollback manually, that worked, but still left the processes as "Idle". So then I called connection.close(), and all is well. But I'm left wondering, why doesn't Django's typical transaction and connection management work for these threaded tasks that are being spawned from the main Django thread?
