  • C# Drawing 2D objects with events

    - by Keeper
    I need to draw several simple objects (polygons composed by lines and arcs, eventually placed on different layers) inside a form (or any other container) and then handle events like: right click on object zoom pan Is there a library/framework that can handle my need or do I need to create my own?

  • Microsoft using PHP instead of ASP.NET ?

    - by Quandary
    Question: I was just browsing http://msdn.microsoft.com/en-us/library/ms190447.aspx?PHPSESSID=tn8k5p1s508cop8gr43e1f34d2 for information about how to restore a database to a new location The interesting part is (my question has nothing to do with databases), why is there a PHP-Session-ID (PHPSESSID) parameter in the ULR if the extension is aspx? Unless one would reroute .aspx to .php ?

  • Why is there a sizeof... operator in C++0x?

    - by Motti
    I saw that @GMan implemented a version of sizeof... for variadic templates which (as far as I can tell) is equivalent to the built in sizeof.... Doesn't this go against the design principle of not adding anything to the core language if it can be implemented as a library function[citation needed]?

  • ZF-Autoloader not working in UnitTests on Ubuntu

    - by Sam
    i got a problem regarding Unit-testing a Zend-Framework application under Ubuntu 12.04. The project-structure is a default zend application whereas the models are defined as the following ./application ./models ./DbTable ./ProjectStatus.php (Application_Model_DbTable_ProjectStatus) ./Mappers ./ProjectStatus.php (Application_Model_Mapper_ProjectStatus) ./ProjectStatus.php (Application_Model_ProjectStatus) The Problem here is with the Zend-specific autoloading. The naming convention here appears that the folder Mappers loads all classes with _Mapper but not _Mappers. This is some internal Zend behavior which is fine so far. On my windows machine the phpunit runs without any Problems, trying to initiate all those classes. On my Ubuntu machine however with jenkins running on it, phpunit fails to find the appropriate classes giving me the following error Fatal error: Class 'Application_Model_Mapper_ProjectStatus' not found in /var/lib/jenkins/jobs/PAM/workspace/tests/application/models/Mapper/ProjectStatusTest.php on line 39 The error appears to really be that the Zend-Autoloader doesn't load from the ubuntu machine, but i can't figure out how or why this works. The question remains of why this is. I think i've double checked every point of contact with the zend autoloading stuff, but i just can't figure this out. I'll paste the - from my point of view relevant snippets - and hope someone of you has any insight to this. Jenkins Snippet for PHPUnit <target name="phpunit" description="Run unit tests with PHPUnit"> <exec executable="phpunit" failonerror="true"> <arg line="--configuration '${basedir}/tests/phpunit.xml' --coverage-clover '${basedir}/build/logs/clover.xml' --coverage-html '${basedir}/build/coverage/.' --log-junit '${basedir}/build/logs/junit.xml'" /> </exec> </target> ./tests/phpunit.xml <phpunit bootstrap="./bootstrap.php"> ... this shouldn't be of relevance ... </phpunit> ./tests/bootstrap.php <?php // Define path to application directory defined('APPLICATION_PATH') || define('APPLICATION_PATH', realpath(dirname(__FILE__) .

'/../library'), get_include_path(), ))); require_once 'Zend/Loader/Autoloader.php'; Zend_Loader_Autoloader::getInstance(); Any help will be appreciated.

  • How do you manage the namespaces of your extension methods?

    - by Robert Harvey
    Do you use a global, catchall namespace for all of your extension methods, or do you put the extension methods in the same namespace as the class(es) they extend? Or do you use some other method, like an application or library-specific namespace? EDIT: I ask because I have a need to extend System.Security.Principal.IIdentity, and putting the extension method in the System.Security.Principal namespace seems to make sense, but I've never seen it done this way.

  • How can I retrieve the instance of an attribute's associated object?

    - by Brandon Linton
    I'm writing a PropertiesMustMatch validation attribute that can take a string property name as a parameter. I'd like it to find the corresponding property by name on that object and do a basic equality comparison. What's the best way to access this through reflection? Also, I checked out the Validation application block in the Enterprise Library and decided its PropertyComparisonValidator was way too intense for what we need.

  • Which namespace does operator<< (stream) go to?

    - by aaa
    If I have have some overloaded ostream operators, defined for library local objects, is its okay for them to go to std namespace? If I do not declare them in std namespace, then I must use using ns:: operator <<. As a possible follow-up question, are there any operators which should go to standard or global namespace?

  • Remove never-run call to templated function, get allocation error on run-time

    - by Narfanator
    First off, I'm a bit at a loss as to how to ask this question. So I'm going to try throwing lots of information at the problem. Ok, so, I went to completely redesign my test project for my experimental core library thingy. I use a lot of template shenanigans in the library. When I removed the "user" code, the tests gave me a memory allocation error. After quite a bit of experimenting, I narrowed it down to this bit of code (out of a couple hundred lines): void VOODOO(components::switchBoard &board){ board.addComponent<using_allegro::keyInputs<'w'> >(); } Fundementally, what's weirding me out is that it appears that the act of compiling this function (and the template function it then uses, and the template functions those then use...), makes this bug not appear. This code is not being run. Similar code (the same, but for different key vals) occurs elsewhere, but is within Boost TDD code. I realize I certainly haven't given enough information for you to solve it for me; I tried, but it more-or-less spirals into most of the code base. I think I'm most looking for "here's what the problem could be", "here's where to look", etc. There's something that's happening during compile because of this line, but I don't know enough about that step to begin looking. Sooo, how can a (presumably) compilied, but never actually run, bit of templated code, when removed, cause another part of code to fail? Error: Unhandled exceptionat 0x6fe731ea (msvcr90d.dll) in Switchboard.exe: 0xC0000005: Access violation reading location 0xcdcdcdc1. Callstack: operator delete(void * pUser Data) allocator< class name related to key inputs callbacks ::deallocate vector< same class ::_Insert_n(...) vector< " " ::insert(...) vector<" "::push_back(...) It looks like maybe the vector isn't valid, because _MyFirst and similar data members are showing values of 0xcdcdcdcd in the debugger. But the vector is a member variable...

  • Implementing "View as HTML" for Word and PDF documents on an intranet

    - by Manne
    I am looking for a way to implement "View as HTML" (as seen in e.g. GMail) for Microsoft Office and Adobe PDF documents stored in an intranet. Can anyone recommend approaches for this? The intranet consists of multiple .NET sites, so I would prefer a .NET library (one that doesn't launch MS Word on the server) for this capability, but any kind of arrangement is welcome.

  • Is there an easy way to merge C# dynamic objects

    - by ajma
    Let's say I have two dynamic objects like this: var objA = new { test = "test", blah = "blah" }; var objB = new { foo = "foo", bar = "bar" }; I want to combine them to get: new { test = "test", blah = "blah", foo = "foo", bar = "bar" }; I won't know what the properties are for both objA and objB at compile time. I want this to be like jquery's extend method. Anybody know of a library or a .net framework class that can help me do this?

  • What is the best approach to use different CFLAGS for the same source files?

    - by evilsocket
    Hello, i need to build the same source tree twice, 1 - with normal cflags to build the project binary 2 - with cflags plus -fPIC to build a static library that would be some sort of SDK to develop project dynamic modules. Using only one Makefile, what is the best approach to accomplish this? It would be nice to do some sort of : all: $(OBJECTS) lib_rule: $(OBJECTS) CFLAGS += -fPIC .cpp.o: $(CC) -c $< -o $@ $(CFLAGS) But obviously it can't be done. Thanks

  • What is this line doing exactly?

    - by mystify
    From the Finch audio library: - (void) play { [[sounds objectAtIndex:current] play]; current = (current + 1) % [sounds count]; // this line here... } I try to grok it: There is a number of sounds n, and current is increased by 1 on every iteration. As soon as current is bigger than number of sounds n, the modulo returns zero. That way, it starts from the beginning. Is this correct?

  • Customized command line parsing in Python

    - by Moshe
    I'm writing a shell for a project of mine, which by design parses commands that looks like this: COMMAND_NAME ARG1="Long Value" ARG2=123 [email protected] My problem is that Python's command line parsing libraries (getopt and optparse) forces me to use '-' or '--' in front of the arguments. This behavior doesn't match my requirements. Any ideas how can this be solved? Any existing library for this?

  • How can I shade a region between two lines in flot?

    - by Oren
    I have had a lot of success creating graphs with Flot. However, I can not seem to figure out how one would go about shading in a region between two lines using the library. My goal is to be able to create shaded regions as illustrated below: I found this plugin, but it appears that it can only shade a range of values of a line, as demonstrated here.

  • Commitment to Zend Framework - any arguments against?

    - by Pekka
    I am refurbishing a big CMS that I have been working on for quite a number of years now. The product itself is great, but some components, the Database and translation classes for example, need urgent replacing - partly self-made as far back as 2002, grown into a bit of a chaos over time, and might have trouble surviving a security audit. So, I've been looking closely at a number of frameworks (or, more exactly, component Libraries, as I do not intend to change the basic structure of the CMS) and ended up with liking Zend Framework the best. They offer a solid MVC model but don't force you into it, and they offer a lot of professional components that have obviously received a lot of attention (Did you know there are multiple plurals in Russian, and you can't translate them using a simple ($number == 0) or ($number > 1) switch? I didn't, but Zend_Translate can handle it. Just to illustrate the level of thorougness the library seems to have been built with.) I am now literally at the point of no return, starting to replace key components of the system by the Zend-made ones. I'm not really having second thoughts - and I am surely not looking to incite a flame war - but before going onward, I would like to step back for a moment and look whether there is anything speaking against tying a big system closely to Zend Framework. What I like about Zend: As far as I can see, very high quality code Extremely well documented, at least regarding introductions to how things work (Haven't had to use detailed API documentation yet) Backed by a company that has an interest in seeing the framework prosper Well received in the community, has a considerable user base Employs coding standards I like Comes with a full set of unit tests Feels to me like the right choice to make - or at least, one of the right choices - in terms of modern, professional PHP development. I have been thinking about encapsulating and abstracting ZF's functionality into own classes to be able to switch frameworks more easily, but have come to the conclusion that this would not be a good idea because: it would be an unnecessary level of abstraction it could cost performance the big advantage of using a framework - the existence of a developer base that is familiar with its components - would partly be cancelled out therefore, the commitment to ZF would be a deep one. Thus my question: Is there anything substantial speaking against committing to the Zend Framework? Do you have insider knowledge of plans of Zend Inc.'s to go evil in 2011, and make it a closed source library? Is Zend Inc. run by vampires? Are there conceptual flaws in the code base you start to notice when you've transitioned all your projects to it? Is the appearance of quality code an illusion? Does the code look good, but run terribly slow on anything below my quad-core workstation?
