  • Error Using PDCurses: Cannot Open File Libc.C

    - by cam
    I'm getting the error: 1>LINK : fatal error LNK1104: cannot open file 'LIBC.lib' Here's my source code: #include <curses.h> int main() { initscr(); /* Start curses mode */ printw("Hello World !!!"); /* Print Hello World */ refresh(); /* Print it on to the real screen */ getch(); /* Wait for user input */ endwin(); /* End curses mode */ return 0; } I've configured the PDcurses library properly (added to Additional Include libraries, added folder to Additional Library Directories). I've looked around for a bit, and I've tried adding Libc.C to the 'Ignore Library' list, which in turn causes about 150 errors. Not sure what to do from here.

  • Java (Android) regular expression to strip out HTML paragraph

    - by jackbot
    I have an Android application which grabs some data from an external XML source. I've stripped out some HTML from one of the XML elements, but it's in the format: <p class="x">Some text...</p> <p>Some more text</p> <p>Some final text</p> I want to extract the middle paragraph text, how can I do this? Would a regular expression be the best way? I don't really want to start including external HTML parsing libraries.

  • "ref" vs "out" keyword errors using the sql-net and C# Sqlite combination for windows phone 7.1

    - by param
    I am getting some "ref" vs "out" keyword errors using the sql-net and C# Sqlite combination for windows phone 7.1. Is this due to a wrong combination of libraries that I am using? App Type: Windows Phone 7.1 Using: 1) sql-net Version 1.0.5, Source Nuget thru Visual Studio 2) C# Sqlite for WP7 (wp7sqlite) ( Community.CSharpSqlite.WP7) Version 0.1.1, Source Nuget thru Visual Studio. The exact error I receive is below **Error 5 The best overloaded method match for Community.CsharpSqlite.Sqlite3.sqlite3_open(string, ref Community.CsharpSqlite.Sqlite3.sqlite3)' has some invalid arguments C:\Dev\Learning\SQLite.cs Line:2492 Column: 29 ** The next error then hints that it is related to the parameter being passed as "out" type instead of "ref" type. Error 6 Argument 2 must be passed with the 'ref' keyword C:\Dev\Learning\SQLite.cs Line: 2492 Column: 64 I can make the compile errors go away by replacing the "out" keyword with the "ref" keyword, but that is likely to lead to other issues. Given that I do not see much complain about this issue - I may be doing something wrong but not able to detect easily. Thanks, Parmeshwar

  • Alternative to BerkeleyDB?

    - by John
    I'm looking for a dbm-like library that I can use in place of Berkeley DB, which I'm currently using. My main reason for switching is the licensing fees for BDB are pretty high (free for open source apps, but my employer does not want to open source this particular app for various reasons). I've looked briefly at qdbm but it doesn't look like it will fill my needs -- lots of keys (several million) and large data items ( 1-5 megabytes). Before I continue my search I figured I'd ask because it seems there are tons of dbm-like libraries out there.

  • How to write a shell in Python

    - by panzi
    I've written a small console application that can perform certain tasks. The user interface is similar to things like version control systems or yum etc. So basically you can think of it as a domain specific language. Now I'd like to write a (bash like) shell that can execute and auto-complete this language and has a command history (so I do not have to load and save the quite large xml files on each command). In a nutshell I want something like ipython but not for executing python code but my own DSL. Are there any libraries that help me doing this? I see that there is a readline and rlcompleter module in python but its documentation seems to indicate that this is only for use with the python shell itself, or did I miss something there?

  • Synchronizing Java Visualizer Audio and Visual

    - by Matt
    I've run into a problem creating a visualizer for .mp3 files in Java. My goal is to create a visualization that runs in time with the .mp3 file being played. I can currently visualize an .mp3 OR play it, but not both at the same time. I am using libraries which may make this trickier than necessary. I currently: Read in the .mp3 as a FileInputStream. a) Convert the FileInputStream into a Bitstream and run the Visualizer OR b) Pass the FileInputStream to a library Play method where it converts it into a Bitstream, decodes it, and plays it. I am using the JLayer library to play and decode the .mp3. My question is: how do I synchronize the two actions so that I can run both at the same time AND they line up (so my visualizations correspond to the changing frequencies). This implies that they finish at the same time as well.

  • Anyone got Twitter xAuth working with the Compact Framework yet?

    - by peSHIr
    This question is related to a number of other questions on oAuth on the Compact Framework (one, two) but seems slightly more specific to me, as it specifically involves getting Twitters xAuth API call (meant for non web applications to be able to do oAuth) working on the Compact Framework. Are SSL HTTP connections and the encryption methods needed for xAuth needed part of Compact Framework 3.5? Did anyone get the Twitter xAuth working on Windows Mobile already? If so, what libraries did you use for this? Any tips are welcome.

  • Bulding an multi-platform SWT application using Ant

    - by Mridang Agarwalla
    I'm writing an SWT application which can be used on Windows (32/64 bit) and Mac OSX (32/64 bit). Apart from the JRE I rely on the SWT library found here. I can find four versions of the SWT library depending upon my target platforms (as mentioned above). When building my application, how can I compile using the correct SWT Jar? If possible, I'd like to try and avoid hard-coding the Jar version, platform and architecture. The SWT Jars are named like this: swt-win32-x86_64.jar swt-win32-x86_32.jar swt-macosx-x86_32.jar swt-macosx-x86_64.jar (My project will be an open source project. I'd like people to be able to download the source and build it and therefore I've thought of including all the four versions of the SWT Jars in the source distribution. I hope this is the correct approach of publishing code relying on third-part libraries.) Thanks everyone.

  • Silent Printing of PDF From Within Java

    - by Paul Reiners
    We are looking into silent printing of PDF documents from within Java. The printing will be invoked from the desktop and not through a browser so we cannot use JavaScript. PDF Renderer is an operational solution but their rendering quality is not acceptable. iText does not seem to be pluggable with the Java print service. There are some commercial Java libraries, jPDFPrint by Qoppa, JPedal, and ICEpdf which we have not tried out yet. Does anybody have any experience with PDF silent printing from Java?

  • java tool for debugging

    - by user269723
    Hi experts, Currently we are studying the java based tool which is primararily Reporting tool.It was developed in 2000/2001 period and uses many open source libraries like Apache Avalon/Mx4J.Adaptor/edu.Oswego(java concurrent package) etc. Tool uses jdk 1.3.1 and goal is to upgrade to jdk 1.5.We have also been asked to remove these 'outdated' packages and replace by standard java packages if possible. Unfortunately we have the code available for study but lacks any documentation and really difficult to track the flow(Total number of classes written might be more than 1000) during debugging. Whats the best way to understand this kind of tool? any Graphical tool to see the relationship between the classes? Thanks SR

  • Upload files with java

    - by Marius
    I'd like to upload a few files to a http server. Basically what i need is some sort of a post request to the server with a few parameters and the files. I've seen examples of just uploading files, but didn't find how to also pass additional parameters. So the question would be what's the simplest and free solution of doing this? Does anyone have any file upload examples that i could study? I've been googling for a few hours, but (maybe it's just one of those days) couldn't find exactly what i needed. The best solution would be something that doesn't involve any third party classes or libraries. Thank you

I have added as a reference the correct libraries to the project and can see the object via intellisense however I am not sure on the correct syntaxt to create an instance of the object. Currently I have the following in my C# project - which the compiler doesn't like... var myObj1 = new Person("mark");

  • Should I be so enthusiastic about Groovy?

    - by rukoche
    I'm currently working on my project which consists of front and back-end written in PHP and desktop app written in Java, and that's what the plan was before I discovered Groovy and later on Grails. Now after rewriting my desktop client and sketching some back-end functionality in Groovy I'm considering to drop PHP altogether in favor of Groovy (although I haven't played around with Grails yet.) For me it just looks like coding in Groovy is as simple as in PHP, but with lots of extra sugar and awesomeness of Java libraries. Comparing those two may sound awkward, but hey I'm an amateur ;) Finally to my question, from the looks of it most of the articles/blog posts about Groovy I can find is awfully outdated. Am I missing some reason why it's not so popular and which will crush my enthusiasm to bits? :D

  • How can I create an .xls file with a readwrite password from Delphi

    - by dummzeuch
    I know that it is possible to create .xls files from Delphi using ADO, OLE automation with Excel and even using several commercial libraries. My requirement now is not just creating a new .xls file and adding data to it but in addition protecting it with a password against editing. I guess this would be possible using OLE automation but that would require an Excel installation on the computer and also add all the potential hassle of OLE automation which I would like to avoid. Does any of the other solutions provide the option of password protecting the file? (Yes, I know this is far from secure, but the customer requests it. Just in case it matters: I am using Delphi 2007.)

  • Finding matches between multiple JavaScript Arrays

    - by Chris Barr
    I have multiple arrays with string values and I want to compare them and only keep the matching results that are identical between ALL of them. Given this example code: var arr1 = ['apple', 'orange', 'banana', 'pear', 'fish', 'pancake', 'taco', 'pizza']; var arr2 = ['taco', 'fish', 'apple', 'pizza']; var arr3 = ['banana', 'pizza', 'fish', 'apple']; I would like to to produce the following array that contains matches from all given arrays: ['apple', 'fish', 'pizza'] I know I can combine all the arrays with var newArr = arr1.concat(arr2, arr3); but that just give me an array with everything, plus the duplicates. Can this be done easily without needing the overhead of libraries such as underscore.js? (Great, and now i'm hungry too!) EDIT I suppose I should mention that there could be an unknown amount of arrays, I was just using 3 as an example.

  • How can one use the "Add view" dialog in Visual Studio efficiently when working with ASP.NET MVC?

    - by Marek
    Does anyone else think that the add view dialog in VS is useless or is it just me? Why is there no search/filtering in there? I can not even paste the type name (without namespace) there to speed up the view creation. Plus, there are a lot of irrelevant classes there, including classes from all referenced libraries. Am I missing something or Microsoft never did any usability testing with that?? Is it possible to filter out types/assemblies in the dialog and/or better navigation compared to manually scrolling the combobox with all the types listed? Is it possible to include only types from a particular directory/assembly/namespace? (the ViewModels namespace for example) EDIT: As it seems from the answers that there is no usable workaround for this, I have filed a suggestion at Connect: https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=507784 Please vote for the suggestion if you find this is an important issue.

  • DocuSign Connect xsd [on hold]

    - by Brian
    I'm trying to parse xml inbound to our system from the DocuSign Connect service (which publishes status updates to a given web service). I typiclly use jaxb to process xml but as far as I know I need xsd's in order to generate the jaxb. I don't have (or can't find) xsd's from DocuSign in order to do this. I could use other java classes/libraries to parse the xml but without xsd's I'd have to guess at types, restrictions and formats. Is there a way to generate jaxb without having xsd's?

  • How to access USB ports in java

    - by Petezah
    Hi I'm trying to write a java application that accesses the usb ports to some read and writes to a device connected through usb. The problem I face is that I don't know what exactly to use in java to do such a thing. I searched online a found something called jusb but all the post seem fairly old. Currently I'm using the RXTX libraries but I sometimes run into some sync error. When I use C# to do the equivalent it requires far less code and I don't face any of the same sync error. My question is there anything built into the latest version of the JRE I can use to access the usb ports that is just as easy as the equivalent C# code? Sorry if the question isn't too clear, I'm fairly noob with coding usb IO.

  • Integrating WebSockets with Rails using Rack and Event Machine

    - by Toby Hede
    I have created an Asynchronous version of Rails 3 that I would like to integrate with a WebSocket implementation. I am using EventMachine, Ruby 1.9, Fibers and various em-flavoured libraries as documented by the wickedly good Ilya Grigorik. I have been looking at em-websocket as the handler for WebSocket connections but unsure of the best approach for hooking this into a Rails app. Ideally, this would work in a similar fashion to node.js with Express and Socket.io - incoming connections should be detected and dispatched to the WebSocket handler or the regular rails stack as indicated by the HTTP headers & etc. TL;DR WebSocket handler that plugs into an existing Rails application Transparently dispatch incoming WebSocket requests to endpoints in the app

  • How popular is C++ for making websites/web applications?

    - by Vilx-
    I don't know why this is question is bugging me, but time after time I come back to the though - why not make websites in C++? So far I know of none (except a rumor about Yahoo). Most use PHP, Java or ASP.NET. Some are built on Ruby or Python, but even those are minorities. At the same time, looking at StackOverflow, it seems that C++ is still a very popular language with many projects written in it. Why not for webpages? So - what do you know about this subject? Are there any websites written in C++? Are there any framewroks/libraries that help doing this? Have YOU ever done it? If yes, did you run into any fundamental problems and would you recommend this to others?

  • Generate an image / thumbnail of a webpage using X/Gui-less linux

    - by dassouki
    There are a lot of solutions out there on generating a thumbnail or an image preview of a webpage. Some of these are websites like websnapshots, windows libraries such as PHP's imagegrabscreen (only works on windows), and KDE's wkhtml. Many more do exist. However, I'm looking for a GUI-less solution. Something I can create an API around and link it to php or python. I'm comfortable with python, php, C, and shell. This is a personal project, so I'm not interested in commercial applications as I'm aware of their existence. Any ideas?

  • Setting up a non-emacs Common Lisp Dev Env for web application development?

    - by Ravi S
    I am trying to set up a Common Lisp Dev Env for web application development on my Ubuntu 10.04 LTS 64-bit box and I can't find a single decent guide that is targeted at noobs. The closest I came is with Peter Seibel's Lisp in a box but I detest Emacs with a passion and it seems to have older versions of SBCL and CLISP (which are my preferred CL implementations). I do not want to use any of the commercial implementations. I am looking for a simple setup to write some very basic CRUD apps involving possibly hunchentoot, some framework like weblocks,CL-WHO, CL-SQl, sqlite or some datastores from the nosql family like mongo and couch.. Assuming, I go with either SBCL or CLISP on Linux, what is the best tool to manage packages and libraries? ASDF? I am looking for simplicity and consistency and I don't expect to use a ton of libs...

  • Maintaining both free and pro versions of an application

    - by Immortal
    I want to create a PRO version of my application for Android and was wondering how to structure my repository. For know I have a trunk and feature branches. I'd like to put a pro version in another branch but maybe there is a better way? For example, maybe I should create two branches - one for free version, the other for pro? Pro version will have additional features and will be ads-free, so eg. I don't want to include AdMob libraries in the pro version. Do you have any experience or suggestions as to what would be the best way to structure the repository in this case?

  • logging in scala

    - by IttayD
    In Java, the standard idiom for logging is to create a static variable for a logger object and use that in the various methods. In Scala, it looks like the idiom is to create a Logging trait with a logger member and mixin the trait in concrete classes. This means that each time an object is created it calls the logging framework to get a logger and also the object is bigger due to the additional reference. Is there an alternative that allows the ease of use of "with Logging" while still using a per-class logger instance? EDIT: My question is not about how one can write a logging framework in Scala, but rather how to use an existing one (log4j) without incurring an overhead of performance (getting a reference for each instance) or code complexity. Also, yes, I want to use log4j, simply because I'll use 3rd party libraries written in Java that are likely to use log4j.
