  • Building a titanium module with xcode that uses other libraries

    - by kudorgyozo
    I have a Titanium module and i want to use it for voice over ip using pjsip. I have changed the project settings the following way: added to the other linker flags the libraries from pjsip added to the header search paths the headers from pjsip added to the library search paths the libraries from pjsip If i do these things for a normap iPhone app it works i can make calls i have tested it and made a wrapper class that has methods like makeCall, hangup. etc. But i want to use this class together with the libraries from pjsip in a Titanium module. It gives me errors like: implicit declaration of function 'pjsua_perror' implicit declaration of function 'pjsua_destroy' 'pjsua_config' undeclared (first use in this function) These are all part of pjsip (pjsua_perror and pjsua_destroy are functions and pjsua_config is a struct) Does it work this way? Can i include other libraries in a library? What is the difference between making an app that uses libraries and making a library that uses libraries?

  • Save a binary file in SQL Server as BLOB and text (or get the text from Full-Text index)

    - by Glennular
    Currently we are saving files (PDF, DOC) into the database as BLOB fields. I would like to be able to retrieve the raw text of the file to be able to manipulate it for hit-highlighting and other functions. Does anyone know of a simple way to either parse out the files and save the raw text on save, either via SQL or .net code. I have found that Adobe has a filtdump utility that will convert the PDF to text. Filtdump seems to be a command line tool, and i don't see a way to use a file stream. And what would the extractor be for Office documents and other file types? -or- Is there a way to pull out the raw text from the Full text index? Note i am trying to build a .net & MSSql solution without having to use a third party tool such as Lucene

  • Why does this window object not have the eval function?

    - by Motti
    I ran into an interesting (?) problem in the YUI rich edit demo on IE. When looking at the window object for the content editable frame used as the browser I see that the eval function is undefined (by running the following). javascript:alert(document.getElementById("editor_editor").contentWindow.eval) This only happens on IE (I checked on IE6 and IE8), and it doesn't happen on Firefox or Chrome. All the other window functions and properties seem to be in order, now I realise that eval is not really defined on the window but on the global object but my understanding was that in browsers the window is the global object (also eval does appear on all other windows so why not on this one?). Does anyone know if this is a know bug/limitation in IE and how I can get to eval in the context of the global object of this frame? (I need the side effects to be available to anything running from within this frame).

  • How to create Server-side Progress indicator in Javascript

    - by Eli
    Hey Guys, I want to create a section in my site, where a user has a few simple update buttons. Each of these update buttons will be going to the server, and will do a long crunching behind the scene. While the server crunches data, I want the user to have a some kind of progress indicator, like progress bar or textual percentage. I'm using jQuery as my javascript library, and CodeIgniter (PHP) as the server-side framework, if it's important... What I was thinking about is using PHP's flush() function to report progress status to jQuery, but I'm not sure that jQuery's ajax functions are reading the output before it's complete... So any advice/explanation would be useful and helpful! Thanks :)

  • Object Slicing, Is it advantage ?

    - by harigm
    Object slicing is some thing that object looses some of its attributes or functions when a child class is assigned to base class. Some thing like Class A{ } Class B extends A{ } Class SomeClass{ A a = new A(); B b = new B(); // Some where if might happen like this */ a = b; (Object slicing happens) } Do we say Object slicing is any beneficial in any ways? If yes, can any one please tell me how object slicing be a helpful in development and where it might be helpful?

  • How to reduce compilation times with Boost Asio

    - by Artyom
    Boost.Asio is great library but it has one huge drawback -- extreamly slow compilation times. A simple implementation (really simple) of HTTP protocol (about 1k lines of code) requires about 13.5s to compile under GCC 4.4! I tryed to use PCH but it does not improve compilation times too much (about 1s. only). So are there any tutorials on how to make Boost.Asio compilation times faster? For example what headers should I exactly include for what class. I use for example: io_service, tcp::ip::sockets, tcp::ip::acceptor, deadline_timer, buffers and few functions like async_read, async_write. Any suggestions? P.S.: I do use pimpl whenever I can.

  • ASP.NET MVC on IIS6

    - by Seb Nilsson
    Where can I find some good pointers on best practices for running ASP.NET MVC on IIS6? I haven't seen any realistic options for web-hosts who provide IIS7-hosting yet. Mostly because I don't live in the U.S. So I was wondering on how you best build applications in ASP.NET MVC and make it easily available to deploy on both IIS6 and IIS7. Keep in mind that this is for standard web-hosts, so there is no access to ISAPI-filters or special settings inside IIS6. Are there anything else one should think about when developing ASP.NET MVC-applications to target IIS6? Any functions that doesn't work? UPDATE: One of the bigger issues is the thing with routes. The pattern {controller}/{action} will work on IIS7, but not IIS6 which needs {controller}.mvc/{action}. So how do I make this transparent? Again, no ISAPI and no IIS-settings, please.

  • linker error in simple program: multiple definition of function

    - by BillyJean
    My function test is added to two different .cpp-files and the functions are private to their respective files as shown below test1.cpp #include <iostream> using namespace std; void test() { cout << "test" << endl; } test2.cpp #include <iostream> using namespace std; void test() { cout << "test" << endl; } main.cpp #include <iostream> using namespace std; int main() { return 0; } During linking I get the error multiple definition of test() - but how is that possible, considering that the two files have their own private scope!? I could understand it if I included the function prototype in each .cpp-files' corresponding header, but there is no such thing in this example.

  • Calculation with RESTful web service with MySQL database

    - by Dobby
    I am now making some RESTful web services with MySQL database. I used NetBeans to create the resources of RESTful service with MySQL, and now I can now use GET and POST/PUT to list and add/modify data entities in the MySQL server. Currently, I wish to make some calculations right after a client makes the POST activities, then the posted data with calculated results will be inserted into the MySQL database. I am very new to this, I guess I need to add some functions and call them to calculate but I don't know where and how to do that : ( Could any one help me on this issue? Thanks a lot in advance! : )

  • seeing C# windows forms project code from F#

    - by Pessimist
    I have a C# Windows Forms project open with some C# code in it. Question: How can I have an F# file that I can write F# code in but still referencing all the C# code I have on Form1.cs (including the GUI). I can successfully do this: - Create a C# Windows Forms project - Create a F# Library project - Reference the F# Library DLL from my C# project - That way I can call F# functions from C# But I still can't see my buttons and textboxes from F# I understand that that is because it's a library and it can't reference System.Windows.Forms So how do I fix this? I don't want it to be a library or this or that, I just want it to be a file that will allow me to write F# code while being able to reference my C# Form and code. I guess you can say I want an F# file that is also a "partial class Form1" so that I can continue writing code for the same Project, but using F# instead. How do I do that?

  • #if 0 as a define

    - by valerio
    I need a way to define a FLAGS_IF macro (or equivalent) such that FLAGS_IF(expression) <block_of_code> FLAGS_ENDIF when compiling in debug (e.g. with a specific compiler switch) compiles to if (MyFunction(expression)) { <block_of_code> } whereas in release does not result in any instruction, just as it was like this #if 0 <block_of_code> #endif In my ignorance on the matter of c/c++ preprocessors i can't think of any naive way (since #define FLAGS_IF(x) #if 0 does not even compile) of doing this, can you help? I need a solution that: Does not get messed up if */ is present inside <block_of_code> Is sure to generate 0 instructions in release even inside inline functions at any depth (i guess this excludes if (false){<block_of_code>} right?) Is standard compliant if possible Thank you

  • jQuery autocomplete function, how to add support for words not available in the database yet?

    - by Lyon
    Hi, I'm looking to implement a tag system like how SO uses on their site, where users can specify multiple tag words. However, on top of all the other autocomplete functions available as jquery plugins, I also want to allow users to enter new words not in the database. Does anyone know of any plugin that can do that? Or if there isn't, how one can add that functionality to an existing autocomplete function? I'm exploring Drew Wilson's autosuggest plugin at the moment, as it supports multiple tags well: http://code.drewwilson.com/entry/autosuggest-jquery-plugin Any help appreciated! Thanks :)

  • WCF - Network Cost

    - by Mubashar Ahmad
    Dear Devs I have a wcf service deployed on IIS with basicHttpBinding and aspNetCompatibilityEnabled=true I have a test client as well which invokes multiple service functions simultaneously. To check the performance of service call on client and server I calculated the Avg time it takes to complete a service request on client(in proxy code) and on server as well. after a test of 8 hrs (server and client were on the same machine) i came to know that average response time on client is around 34ms where as the Avg execution time on server is around 3ms so the difference is 31ms. I would like to know why every call is taking 31ms is it justified? and how can i reduce this?

Thanks a lot!

  • What's the difference between IEquatable and just overriding Object.Equals() ?

    - by devoured elysium
    I want my Food class to be able to test whenever it is equal to another class. I will later use it against a List, and I want to use its List.Contains() method. Should I implement IEquatable or just override Object.Equals()? From MSDN: This method determines equality by using the default equality comparer, as defined by the object's implementation of the IEquatable.Equals method for T (the type of values in the list). So my next question is: which functions/classes of the .NET framework make use of Object.Equals()? Should I use it in the first place? Thanks

  • How can I "best fit" an arbitrary cairo (pycairo) path?

    - by Daniel Straight
    It seems like given the information in stroke_extents() and the translate(x, y) and scale(x, y) functions, I should be able to take any arbitrary cairo (I'm using pycairo) path and "best fit" it. In other words, center it and expand it to fill the available space. Before drawing the path, I have scaled the canvas such that the origin is the lower left corner, up is y+, right is x+, and the height and width are both 1. Given these conditions, this code seems to correctly scale the path: # cr is the canvas extents = cr.stroke_extents() x_size = abs(extents[0]) + abs(extents[2]) y_size = abs(extents[1]) + abs(extents[3]) cr.scale(1.0 / x_size, 1.0 / y_size) I cannot for the life of me figure out the translating though. Is there a simpler approach? How can I "best fit" a cairo path on its canvas? Please ask for clarification if anything is unclear in this question.

  • Routing and URI parsing in Codeigniter

    - by bobo
    I have a route defined in CI, $route['user/activate-account/:any'] = "user/activate_account"; People access the route in this url pattern, http://mydomain.com/user/activate-account/user_id/12345/token/abcdefghijk Inside the activate_account function, I tried to use the following codes to retrieve the required data, $user_id=$this->input->get('user_id'); $token=$this->input->get('token'); But they return FALSE, does this mean that for this kind of url pattern, I am supposed to use the functions provided by the URI class (http://codeigniter.com/user_guide/libraries/uri.html) to retrieve the variables?

  • Using Yii framework, what would be a right way to process an attribute before displaying it using CH

    - by Karolis
    Say I have this line of code in the view. <?php echo CHtml::activeTextField($model,'start_time'); ?> start_time is a UNIX timestamp. When just displaying it in a view I can apply functions like date() on it. Where should I apply the formatting when I'm displaying it in a form, by using the above line of code? (This case of timestamps/dates might be special, but I'm also interested in how would one go about if it wasn't a date and I just want to work with "value in database" < "different representations of the value in different views. Thanks =)

  • How can I create a javascript library in a separate file and "include" it in another?

    - by Jordan L. Walbesser
    First, a caveat. The main script is not run in a webpage. I will be running the .js file in Windows using Windows Script Host. The problem: I would like to create a javascript "library" containing a number of objects, each with a number of functions. I expect this library will get rather large with time and would like to keep it in a separate javascript file (let's call it Library.js). I would like to access the objects from Library.js from another script (let's call this one User.js). In essence, I am looking for something similar to the C/C++ "include" paradigm. Is there anyway to implement this in javascript? (Remember, this is not web-based)

  • CSS : overflow : auto will not work under FireFox 3.6.2

    - by Michael Mao
    Hello everyone: This is a CSS related question, I got one good answer from my previous question, which suggested to use some CSS code like overflow:auto together with a fixed height container. And here is my actual implementation : on uni server Please follow the instructions on screen and buy more than 4 kinds of tickets. If you are using IE8, Opera, Safari, Chrome, you would notice that the lower right corner of the page now has a vertical scroll bar, which scrolls the content inside it and prevent it from overflowing. That's what I want to have in this section. Now the problem is, this would not do in FireFox 3.6.2. Am I doing something not compliant to the CSS standard or FireFox has its own way of overflow control? You can inspect the elements on screen, and all controlling functions are done in one javascript using jQuery. All CSS code are kept in a separated file as well. According to the professor, FireFox would be the target browser, although the version was set to 2.0...

  • ActionMailer execution timeout

    When trying to send an email to the user for reseting their password, I keep getting an execution timed out error. Other mailer functions work, so I know that the config settings are correct. The header reads: "Timeout::Error in Password resetsController#create" Here is the password_resets_controller: def create @user = User.find_by_email(params[:email]) if @user User.deliver_password_reset_instructions(@user.id) flash[:notice] = "Instructions to reset your password have been emailed to you.
