• Referencing control on one form from another form VB.NET

  - by Tom

  My gosh man, why is this so complicated in VB.NET? As you can guess, I'm kind of new to .NET and just want to reference a control on one form from another. Usually I would just do Form.Control.Property but that doesn't work and every example I've found through Google doesn't work for me. It just seems overly complicated with public classes, etc. Is there a more simpler way to do this? I'm ready to throw in the towel and just use a global variable at this point. I have the form containing the control I want to reference, frmGenerate which has a textbox called txtCustomerNo. From this form through a button's click event I want to show another form, frmCustomers, and have that form reference the value in txtCustomerNo. frmCustomers.ShowDialog() It has to be something simple that I'm just not grasping. Thanks.

• Maven easyb plugin java heap space settings?

  - by vinnu

  Hi, I attempted to change my heap size for maven easyb plugin http://www.easyb.org/maven-easyb-plugin/. In my easyb test I added standard code to print the heap size using the code Runtime.getFreeMemory() and Runtime.getTotalMemory(). I tried setting the MAVEN_OPTS=-Xmx1024m -Xms1024m and also set the maven opts in Maven surefire plugin. Now when I run the same class from the Junit I can see the getTotalMemory() displaying a number close 1Gig but the when the same classes are invoked from easyb plugin they do not reflect the memory size. Shouldn't there be a way of passing JVM opts to maven easyb plugin when it runs these easyb tests? At the very minimum it should atleast pick up the MAVEN_OPTS settings from the environment. Has someone bumped into problems like this? (A search on this group's archive does not reveal much)

• Serialising and Deserialising Requests and Responses exactly as WCF does

  - by PeteAC

  I need to deserialise SOAP request XML to .Net request object and to serialise .Net response object to SOAP response XML. I need this to work exactly as WCF does, using the same XML element local names and namespace URIs. The .Net request and response classes were generated from WSDL using SVCUTIL. I have looked at XmlSerializer class, which does most of it, but doesn't take notice of certain WCF-specific custom attributes, like MessageBodyMemberAttribute. I also looked at DataContractSerializer, but that had exceedingly strange ideas about what element names and namespaces to use. Finally, I tried XmlSerializer with an XmlTypeMapping generated by a SoapReflectionImporter; this didn't seem to use any namespaces at all. I rather suspect that I need to be using one of the above techniques, but with some additional subtlety, of which I am unaware. But perhaps there is an entirely different approach? All suggestions welcome.

• 0.20.2 API hadoop version with java 5

  - by abdeslam

  I have started a maven project trying to implement the MapReduce algorithm in java 1.5.0_14. I have chosen the 0.20.2 API hadoop version. In the pom.xml i'm using thus the following dependency: < dependency < groupId>org.apache.hadoop< /groupId> < artifactId>hadoop-core< /artifactId> < version>0.20.2< /version> < /dependency But when I'm using an import to the org.apache.hadoop classes, I get the following error: bad class file: ${HOME_DIR}\repository\org\apache\hadoop\hadoop-core\0.20.2\hadoop-core-0.20.2.jar(org/apache/hadoop/fs/Path.class) class file has wrong version 50.0, should be 49.0. Does someone know how can I solve this issue. Thanks.

• Type hinting and optional attributes in PHP

  - by Álvaro G. Vicario

  I have a class method that deals with dates: public function setAvailability(DateTime $start, DateTime $end){ } Since item availability can have lower limit, upper limit, both or none, I'd like to make setAvailability() accept NULL values as well. However, the NULL constant violates the type hinting: $foo->setAvailability(NULL, $end); triggers: Catchable fatal error: Argument 1 passed to Foo::setAvailability() must be an instance of DateTime, null given And, as far as I know, I cannot have a DateTime instance with no value. (Can I?) For a reason I cannot grasp, this seems to work: public function setAvailability(DateTime $start=NULL, DateTime $end=NULL){ } ... $foo->setAvailability(NULL, $end); But it looks like a hack that works by pure chance. How would you deal with unset dates in PHP classes?

• How do I map repeating columns in NHibernate without creating duplicate properties

  - by Ian Oakes

  Given a database that has numerous repeating columns used for auditing and versioning, what is the best way to model it using NHibernate, without having to repeat each of the columns in each of the classes in the domain model? Every table in the database repeats these same nine columns, the names and types are identical and I don't want to replicate it in the domain model. I have read the docs and I saw the section on inheritance mapping but I couldn't see how to make it work in this scenario. This seems like a common scenario because nearly every database I've work on has had the four common audit columns (CreatedBy, CreateDate, UpdatedBy, UpdateDate) in nearly every table. This database is no different except that it introduces another five columns which are common to every table.

• Python unittest with expensive setup

  - by Staale

  My test file is basically: class Test(unittest.TestCase): def testOk(): pass if __name__ == "__main__": expensiveSetup() try: unittest.main() finally: cleanUp() However, I do wish to run my test through Netbeans testing tools, and to do that I need unittests that don't rely on an environment setup done in main. Looking at http://stackoverflow.com/questions/402483/caching-result-of-setup-using-python-unittest - it recommends using Nose. However, I don't think Netbeans supports this. I didn't find any information indicating that it does. Additionally, I am the only one here actually writing tests, so I don't want to introduce additional dependencies for the other 2 developers unless they are needed. How can I do the setup and cleanup once for all the tests in my TestSuite? The expensive setup here is creating some files with dummy data, as well as setting up and tearing down a simple xml-rpc server. I also have 2 test classes, one testing locally and one testing all methods over xml-rpc.

• Profiling Java running by JNI calls

  - by Guy

  Hi, I have a C++ code that upon execution: Loads JVM (I have full control on how to load the JVM), and call Java methods (from loaded classes) using C JNI code. The Java code has no Main() and it is actually not a standard Java application. it is mainly a static code that compiled and compacted into Jar file, the code is being called by the C++ module. Is it possible to profile this Java code being executed by YourKit (have license for it)? If so I'll be glad to know how. Thanks, Guy

• How to track dealloc of an abstract object class (NSMutable...)

  - by Thomas Tempelmann

  I have a bug in my code caused by a premature freeing of a ObjC object. I seem not to be able to find it by just looking at my code. There's usually a simple trick to track the dealloc to any class: Implement dealloc, and set a breakpoint. This even usually works with standard objects, by subclassing them and making sure I instantiate the subclass instead of the standard class. However, this does not seem to work with NSMutableArray, and probably neither with similar NSMutable... classes. Some explanations for this can be found here: link text Any other ideas how to track the dealloc invocation of a particular class or object so that I can see the call stack? It's probably possible with DTrace. Any pointers without having to read the entire dtrace docs first?

• Using a backwards relation (i.e FOO_set) for ModelChoiceField in Django

  - by Bwmat

  I have a model called Movie, which has a ManyToManyField called director to a model called Person, and I'm trying to create a form with ModelChoiceField like so: class MovieSearchForm(forms.Form): producer = forms.ModelChoiceField(label='Produced by', queryset=movies.models.Person.producer_set, required=False) but this seems to be failing to compile (I'm getting a ViewDoesNotExist exception for the view that uses the form, but it goes away if I just replace the queryset with all the person objects), I'm guessing because '.producer_set' is being evaluated too 'early'. How can I get this work? here are the relevant parts of the movie/person classes: class Person(models.Model): name = models.CharField(max_length=100) class Movie(models.Model): ... producer = models.ForeignKey(Person, related_name="producers") director = models.ForeignKey(Person, related_name="directors") What I'm trying to do is get ever Person who is used in the producer field of some Movie.

• Rails + simple role system through associative table

  - by user202411

  So I have the Ninja model which has many Hovercrafts through ninja_hovercrafts (which stores the ninja_id and the hovercraft_id). It is of my understanding that this kind of arrangement should be set in a way that the associative table stores only enough information to bind two different classes. But I'd like to use the associative table to work as a very streamlined authorization hub on my application. So i'd also like this table to inform my system if this binding makes the ninja the pilot or co-pilot of a given hovercraft, through a "role" field in the table. My questions are: Is this ugly? Is this normal? Are there methods built into rails that would help me to automagically create Ninjas and Hovercrafts associations WITH the role? For exemple, could I have a nested form to create both ninjas and hcs in a way that the role field in ninjas_hovercrafts would be also filled? If managing my application roles this way isn't a good idea, whats the non-resource heavy alternative (my app is being designed trying to avoid scalability problems such as excessive joins, includes, etc) thank you

• Does a Category applied to NSString also apply to NSCFString via the "toll-free bridge"?

  - by half_brick

  We're integrating a library into an iPhone app which appears to use the google toolbox for iPhone internally. The google toolbox adds a method gtm_stringBySanitizingAndEscapingForXML to NSString. The problem is, whenever we attempt to make a call to this library we get [NSCFString gtm_stringBySanitizingAndEscapingForXML]: unrecognized selector sent to instance 0x272478 So it appears the library is calling that method on a NSCFString, to which the category does not apply. So... is it the case that the category will not apply across the toll-free bridge to CoreFoundation classes? If that's the case then we at least know why it's blowing up. Figuring out how to fix it is a different matter.

• Howto check if a object is connected to another in hibernate

  - by codevourer

  Imagine two domain object classes, A and B. A has a bidirectional one-to-many relationship to B. A is related to thousands of B. The relations must be unique, it's not possible to have a duplicate. To check if an instance of B is already connected to a given instance of A, we could perform an easy INNER JOIN but this will only ensure the already persisted relations. What about the current transient relations? class A { @OneToMany private List<B> listOfB; } If we access the listOfB and perform a check of contains() this will fetch all the connected instances of B lazy from the datasource. I only want to validate them by their primary-key. Is there an easy solution where I can do things like "Does this instance of A is connected with this instance of B?" Without loading all these data into memory and perform a based on collections?

• C++ - Where to code a member function for an inherited object.

  - by Francisco P.

  Hello! I have a few classes (heat, gas, contact, pressure) inheriting from a main one (sensor). I have a need to store them in a vector<Sensor *> (part of the specification). At some point in time, I need to call a function that indiscriminately stores those Sensor *. (also part of the specification, not open for discussion) Something like this: for(size_t i = 0; i < Sensors.size(); ++i) Sensors[i]->storeSensor(os) //os is an ofstream kind of object, passed onwards by reference Where and how shall storeSensor be defined? Is there any simple way to do this or will I need to disregard the specification? Mind you, I'm a beginner! Thanks for your time!

• C# / IronPython Interop and the "float" data type

  - by Adam Haile

  Working on a project that uses some IronPython scripts to as plug-ins, that utilize functionality coded in C#. In one of my C# classes, I have a property that is of type: Dictionary<int, float> I set the value of that property from the IronPython code, like this: mc = MyClass() mc.ValueDictionary = Dictionary[int, float]({1:0.0, 2:0.012, 3:0.024}) However, when this bit of code is run, it throws the following exception: Microsoft.Scripting.ArgumentTypeException was unhandled by user code Message=expected Dictionary[int, Single], got Dictionary[int, float] To make things weirder, originally the C# code used Dictionary<int, double> but I could not find a "double" type in IronPython, tried "float" on a whim and it worked fine, giving no errors. But now that it's using float on both ends (which it should have been using from the start) it errors, and thinks that the C# code is using the "Single" data type?! I've even checked in the object browser for the C# library and, sure enough, it shows as using a "float" type and not "Single"

• frameworks for coding a php library?

  - by ajsie

  there are plenty of frameworks for coding MVC web applications. this time im going to code a library (think of Doctrine or Solr) with a bunch of class files. u just include a bootstrap or a class file and you are ready to use my classes. i have never tried to code a library before and intend to code one for learning purpose so that i can use various design patterns i have learned. are there any great frameworks for this, how i should organize the different class files, where i can put configuration files and so on? tutorials or other information would be great too. thanks

• What's the easiest way to implement background downloading in Wicket?

  - by David Moles

  I've got a simple Wicket form that lets users select some data and then download a ZIP file (generated on the fly) containing what they asked for. Currently the form button's onSubmit() method looks something like this: public void onSubmit() { IResourceStream stream = /* assemble the data they asked for ... */ ; ResourceStreamRequestTarget target = new ResourceStreamRequestTarget(stream); target.setFileName("download.zip"); RequestCycle.get().setRequestTarget(target); } This works, but of course the request stops there and it's impossible to display any other feedback to the user. What I'd like to have is something like the typical "Your requested download [NAME] should begin automatically. If not, click this link." Ideally, still displaying the same page, so the user can immediately select some different data and download that as well. I imagine it's possible to do this using Wicket's Ajax classes, but I've managed to avoid having to use them so far, and it's not immediately obvious to me how. What's my quickest way out, here?

  I have an application with the FrontEnd separated into one Project file and the Codebehind/classes separated into a completely different class library. What I need is a way to, from the UserControl Type, obtain it's VirtualPath. Typically, we would have this in code Board uc = (Board)Page.LoadControl(@"~\Board.ascx"); But I want is something like this Board uc = (Board)Page.LoadControl(Board.VirtualPath); OR Board uc = Page.LoadControl(Board); Anyone have an idea how I can accomplish this?

• Ruby on Rails - Working with times

  If in a database (MySQL), I have a datetime column (ex. 1899-12-30 19:00:00), how do I sum 1 day to it? Following http://corelib.rubyonrails.org/classes/Time.html#M000240 If I want to add 1 day, it actually adds 60*60*24 days (86,400 days) r=Record.find(:first) =>Sat, 30 Dec 1899 19:00:00 -0600 r.date + (60*60*24) =>Fri, 20 Jul 2136 19:00:00 -0600 But if I do this it actually adds 1 day: t = Time.now =>Mon Jun 14 10:32:51 -0600 2010 t + (60 * 60 * 24) =>Tue Jun 15 10:33:21 -0600 2010 I guess it has to do with the format...how do I make this work?

• What should I do to recompile my static library (originally written in VS6) in visual studio 2008?

  - by user370387

  There is a static library A with c++ classes wrapped by a C API in VS6. I developed a static library B in VS6 using callbacks from library A. The library B is used by the program C (commercial software) as a "user defined library" and linked to produce the program D. Questions: 1) When program C uses VS 6 it works, should it work fine with VS 2008? Because it doesn't. 2) When I tried to recompile library B in VS 2008 it gave me a .lib file with only 28KB, and the old one had more than 2MB. Is it ok? What Am I probably doing wrong? Thanks in advance

• How do I prevent an https response from throwing an AuthenticationException with Fiddler running?

  - by Ichabod Clay

  Relative newbie to C# here :) I'm currently creating a web link scraper and having issues with the responses I'm getting when trying to login to the website via my program. I'm trying to use Fiddler to see if my program is sending the proper data, but my program is throwing an AuthenticationException when trying to get a response from the site with Fiddler running. The requests are being sent over HTTPS and Fiddler's certificate is the cause of the excepting being thrown. My question is, what can I implement into my program to have it disregard the certificate authentication? As far as my program goes, the requests and responses are being handled by HttpWebRequest and HttpWebResponse classes.

• WAS Non-HTTP activation - hooking application startup

  - by Mike Tours

  I'm trying to integrate a netTcpBinding based application that is hosted inside WAS with an IoC container (autofac/spring). Unfortunately, when it starts inside WAS and due to the fact that it is not an Http based application, no events are fired inside the Global application class. I need to catch the application domain startup so that I can configure the IoC container. Is there any way to do this when hosting in WAS? I've seen horrible things involving using static classes inside App_Code folders, but I'd like something somewhat more testable and not quite as dirty.

• Securing input of private / protected methods?

  - by ts

  Hello, normally, all sane developers are trying to secure input of all public methods (casting to proper types, validating, sanitizing etc.) My question is: are you in your code validating also parameters passed to protected / private methods? In my opinion it is not necessary, if you securize properly parameters of public methods and return values from outside (other classes, db, user input etc...). But I am constantly facing frameworks and apps (ie. prestashop to name one) where validation is often repeated in method call, in method body and once again for securize returned value - which, I think, is creating performace overhead and is also a sign of bad design.
