• Standard C++ method for validating a URLs format?

  - by Jakobud

  Is there a easy standards-compliant way to check if a URL string is a valid format? Either through a specific URL-type class or maybe someone could show me how to do a regex validation of it?

• Call c++ library from c#

  - by Batul

  Hello All, This question might seem a repeat of previous ones. I have read through a series of posts, but not completely clear for my situation. I have a c++ library which is created using momentics IDE. I have to be able to use this library into a c# project. Someone had been working on this project before being handed over to me. Currently, there are 2 layers for making this possible. First, a c++ project includes the complete library with a c++ wrapper. This project creates a dll as the output. This c++ dll is then fed to a c# project, which has dllimport calls to the c++ dll. This c# project again creates a dll. Finally, in order to use the library in c# application, I have to include a reference to both of these dlls. Is this the correct way to get it working? I was thinking probably there should be a way to simplify the process. Can someone please help me with this question?

• XCode vs VS2008 or how to work with a static library project on XCode

  - by VansFannel

  Hello. I've working with Visual Studio for a long time and now I'm working with XCode. On Visual Studio I can work with more than one project at the same time adding them to a solution (imagine a solutin with a windows application project and a library project). Now I have XCode and two projects: an iPhone application and a static library. Is there something similar to Visual Studio's solution on XCode? If the answer is not, how can I link my iPhone application with the static library? Thank you.

• can I use the IOC when using a 3rd party library

  - by Greg

  Hi, Q1 If I have a reusable library that is available, that uses interfaces with classes that use the getInstance concept to create concrete classes for you to use, then in this case would that make sense on the client side to use the IOC container to create instances of these classes? Or is that really applying a double layer of abstraction? Q2 Or in the cases where I'm building the reusable library myself and want the client to use an IOC container, then in my reusable library would I then dispense with any overhead of having factories or "getInstance" methods to instantiate the classes in the client? (i.e. as the IOC container would do this no?)

• 32bit 64bit referenced library

  - by bleevo

  Hi, I am developing an application that has two DLLs one is a 32bit version another is 64bit version, Client is 32bit Server is 64bit My question is is there a way I can say use the 32bit dll when doing Debug/Release and use 64bit dll when I perform a publish. I realize I can solve this problem using NAnt or MSBuild but was wondering if I can do any of this in visual studio. UPDATE All my code will run on either 32bit or 64bit but I am using a library that has a 32bit library and a 64bit library. 32bit wont work on server, 64bit wont work on dev machine

• C++ / error LNK2019 - XpokerEval library

  - by user1068115

  I have been struggling all the afternoon with the XPokerEval Library I downloaded here: http://www.codingthewheel.com/archives/poker-hand-evaluator-roundup#xpokereval I am trying to make the XPokerEval.PokerSim work, using Visual C++ 2010 express but i get the following errors: 1>psim_test.obj : error LNK2019: unresolved external symbol "void __cdecl SimulateHand(char const *,struct SimResults *,float,float,unsigned int)" (?SimulateHand@@YAXPBDPAUSimResults@@MMI@Z) referenced in function _wmain 1>psim_test.obj : error LNK2019: unresolved external symbol "unsigned int __cdecl RankHand(int const *)" (?RankHand@@YAIPBH@Z) referenced in function _wmain Do you think this can be due to a missing link to a library or a incompatibility with my IDE? The script uses the Pokersource Poker-Eval library which is also included in the zip file, I added to the project directories but it still does not work! I cannot figure out why and I am getting mad! Thanks in advance for any tips on this!

• Validate a single property with the Fluent Validation Library for .Net

  - by Blegger

  Can you validate just a single property with the Fluent Validation Library, and if so how? I thought this discussion thread from January of 2009 showed me how to do it via the following syntax: validator.Validate(new Person(), x => x.Surname); Unfortunately it doesn't appear this works in the current version of the library. One other thing that led me to believe that validating a single property might be possible is the following quote from Jeremy Skinners' blog post: "Finally, I added the ability to be able to execute some of FluentValidation’s Property Validators without needing to validate the entire object. This means it is now possible to stop the default “A value was required” message from being added to ModelState. " However I do not know if that necessarily means it supports just validating a single property or the fact that you can tell the validation library to stop validating after the first validation error.

• gdata api + javascript library for accessing documents?

  - by user246114

  Hi, I wanted to do the following with the gdata javascript library: get a list of a user's documents. read the contents of a chosen document. edit its contents, update the document. If I'm reading correctly, this is not supported by the javascript library? I got this to work with the java library, but would like to push this functionality to the client. Is it possible? If not, are there any ways around it? Thank you

• Packaging a Bundle with a static library

  - by 4thSpace

  I have a static library that includes some xibs. These will basically be the same across projects. I'd like to include the xibs as part of the library. I can include their veiwcontrollers, reference these controllers in the calling project but then there isn't a xib to load. When I right click the xib in the library project, it can't be part of the target. I thought about creating a CFPluginBundle but that creates a new project. I'd loose all of my IBOutlet and IBAction references. What is the best way to reuse xibs that also have outlets and actions to specific controllers?

• Undefined reference to cmph functions even after installing cpmh library

  - by user1242145

  I am using gcc 4.4.3 on ubuntu. I installed cmph library tools 0.9-1 using command sudo apt-get install libcmph-tools Now, when I tried to compile example program vector_adapter_ex1.c , gcc is able to detect cmph.h library in its include file but is showing multiple errors like vector_adapter_ex1.c:(.text+0x93): undefined reference to cmph_io_vector_adapter' vector_adapter_ex1.c:(.text+0xa3): undefined reference tocmph_config_new' vector_adapter_ex1.c:(.text+0xbb): undefined reference to cmph_config_set_algo' vector_adapter_ex1.c:(.text+0xcf): undefined reference tocmph_config_set_mphf_fd' even though, these are all defined in the source code of the cmph library. Could anyone tell the error that might have occurred or suggest an alternate method to go about building minimal perfect hash functions.

• How to add a dynamic library to Android?

  - by Malcolm

  I want to add a non-native shared library to Android so every application on the device would be able to use it. I mean using packaged classes just like a core library as if they were present in the application itself. I studied Android source code to figure out a way to add a new path to the application ClassLoader and found out that it is created during startup and there's no way to change the paths later. I can use my own ClassLoader, but all I will get after loading a class will be a reference to a Class object. This way I will be bound to work through reflection mechanism, which is slower than the native execution system. Is there any way to organise a shared library on Android?

• Where is the Bonjour COM library?

  - by Twelve47

  I've downloaded and installed the Bonjour SDK for Windows on my Win7 64bit machine. I've tried to build both of the the projects in C:\Program Files\Bonjour SDK\Samples\CS. However they both reference Bonjour, causing me to get the following build error 'Cannot load type library for reference "Bonjour". Library not registered.' Bonjour appears to be installed properly as I can run the Bonjour Printer Wizard and it appears to work properly. Any idea why Visual Studio can't find the Library? I'm using Visual Studio 2008 by the way.

• How do I tweet, using the DotNetOpenAuth library?

  - by MedicineMan

  I just downloaded the DotNetOpenAuth library and ran the AuthConsumer demo. It is an excellent library so far! Everything worked as advertised, which has not been my experience with a lot of Facebook and Twitter sample code that I have been working with recently. What I am trying to figure out is: How do I tweet using this library? I am currently planning to implement this in ASP MVC, but my initial thoughts is that the presentation platform doesn't matter all that much at the level I'm looking at.

• Using an XML Catalog with a Java library that uses JAXP internally

  - by Brian Ferris

  I'm using the Apache web service xml rpc library to make requests to an rpc service. Somewhere in that process is a xml document with a DTD reference to http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd, which the library attempts to download when parsing the XML. That download fails with a 503 status code because the w3c is blocking repeated downloads of this largely static document from Java clients. The solution is XML Catalogs to locally cache the DTD. However, while I can find examples of setting an EntityHandler on a JAXP SAXParser instance directly to enable catalog parser support, I don't actually have access to the underlying parser here. It's just being used by the xml rpc library. Is there any way I can set a global property or something that will tell JAXP to use XML catalogs?

• Eclipse and python: library will import in interprer, but not in IDE

  - by John

  I'm running Windows 7, Python 2.6.4 and the latest version of Eclipse. I downloaded the boto library (http://code.google.com/p/boto/) and ran python setup.py install, which created boto-1.9b-py2.6.egg in C:\Python26\Lib\site-packages. Importing a class - say, by doing 'from boto.sqs.connection import SQSConnection' - works fine from the python command line tool. But Eclipse will not find boto, despite the fact that it is using the same python interpreter as I am using when at the command line. I added the library as an external source folder, but that didn't work either. How can I properly import the boto library into Eclipse? Thanks.

• Any Java library for address extraction from emails?

  - by Hans Klock

  I'm looking for an Java open-source library which is able to extract address information from a (German) email (signature). The library should find name street city, city code/postal code email tel/fax address-parser.com is an commercial product, but a free (albeit simple) library would be great. stackoverflow.com/questions/16413/parse-usable-street-address-city-state-zip-from-a-string is asking for something similar, but my problem is broader because the address information is hidden in a complete email. And there isn't a solution either... Any ideas?

• OS X contains heapsort in stdlib.h which conflicts with heapsort in sort library

  - by CryptoQuick

  I'm using Ariel Faigon's sort library, found here: http://www.yendor.com/programming/sort/ I was able to get all my code working on Linux, but unfortunately, when trying to compile with GCC on Mac, its default stdlib.h contains another heapsort, which unfortunately results in a conflicting types error. Here's the man page for Apple heapsort: http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man3/heapsort.3.html Commenting out the heapsort in the sort library header causes a whole heap of problems. (pardon the pun) I also briefly thought of commenting out my use of stdlib.h, but I use malloc and realloc, so that won't work at all. Any ideas?

• OpenIDenabled PHP library with Google Openid

  - by siddhant3s

  I am using JanRain OpenID Library PHP. I am trying out the consumer example in /example/consumer. Services like Google (or Yahoo) are not working, while other's like myopenid.com, blogger are working. My PHPinfo says that cURL and OpenSSL is enabled. Note that I also tried using LightOpenID Library (gitorious.org/lightopenid) which works with Google. Unfortunately, it doesn't work on server with php safe_mode On, it requires cURL. So I cannot use on all servers. JanRain's Library works on the server but not with Google.

• .NET Library to Identify Pitches

  - by Antoni

  I'd like to write a simple program(preferably in C#) to which I sing a pitch using a mic and the program identifies to which musical note that pitch corresponds. Thank you very much for your prompt responses. I clarify: I'd like a (preferably .NET) library that would identify the notes I sing. I'd like that such a library: Identifies a note when I sing(a note from the chromatic scale). Tells me how much I'm off from the closest note. I intend to use such a library to sing one note a time.

• C++ library for generating a SOAP message using WSDL

  - by Harsha Reddy

  Hi guys, Do you know of any C++ libraries can can generate SOAP messages using the WSDL. I am writing a C++ client application and am looking for such a library. I however cannot use gSoap and wsdlpull. SOAP Client library (SQLData Systems) looks like another library which could help me (though I am not too sure) but its results page shows an error while dealing with Apache Axis and I might have to use that. Are there any other libraries? Thanks for the help. Regards, Harsha

• Choosing a plotting library for web/browser application

  - by Goro

  Hello, I am looking for a plotting/graphing library (mostly to do line plots) for my application. I have been looking at JavaScript APIs (like Google's) but I found them to be slowing down things at client side (I am plotting a quite large number of points). I also found that with client-side libraries, the performance was quite varied depending on the user's computer. With moving to a server-side library I would cut down on this variance, and would have more control over data flow (my data is in a MySQL database). I have then looked at some PHP-based plotting libraries, but a lot of them seem to be "forgotten" (no new version for years). I have been eying pChart, but it has not had an update in almost two years. First, what would you recommend: server-side or client-side approach? Second, what library would you recommend. Paid libraries are definitely an option, as I don't mind paying for quality software that would cut down on my development time. Thanks,
