• c# passing method names as the argument in a method

  - by Alan Bennett

  hi guys, I have a recuring method which shows up many times in my code its basically checking to make sure that the connection to the odbc is ok and then connects but each time this method is called it calls another method and each instance of the main method this one is different, as each method is about 8 lines of code having it 8 times in the code isnt ideal. so basically i would like to have just one method which i can call passing the name of the new method as an arguement. so basically like: private void doSomething(methodToBeCalled) { if(somthingistrue) { methodToBeCalled(someArgument) } } is this possible? thanks in advance

• Initializing static pointer in templated class.

  - by Anthony

  This is difficult for me to formulate in a Google query (at least one that gives me what I'm looking for) so I've had some trouble finding an answer. I'm sure I'm not the first to ask though. Consider a class like so: template < class T > class MyClass { private: static T staticObject; static T * staticPointerObject; }; ... template < class T > T MyClass<T>::staticObject; // <-- works ... template < class T > T * MyClass<T>::staticPointerObject = NULL; // <-- cannot find symbol staticPointerObject. I am having trouble figuring out why I cannot successfully create that pointer object. Edit: The above code is all specified in the header, and the issue I mentioned is an error in the link step, so it is not finding the specific symbol.

• Concise (yet still expressive) C++ syntax to invoke base class methods

  - by ShaChris23

  I want to specifically invoke the base class method; what's the most concise way to do this? For example: class Base { public: bool operator != (Base&); }; class Child : public Base { public: bool operator != (Child& child_) { if(Base::operator!=(child_)) // Is there a more concise syntax than this? return true; return false; } };

• postgresql duplicate table names best practice

  - by veilig

  My company has a handful of apps that we deploy in the websites we build. Recently a very old app needed to be included along side a newer app and there was a conflict w/ a duplicate table name needed to be used by both apps. We are now in the process of updating an old app and there will be some DB updates. I'm curious what people consider best practice (or how do you do it) to help ensure these name collisions don't happen. I've looked at schema's but not sure if thats the right path we want to take. As the documentation prescribes, I don't want to "wire" a particular schema name into an application and if I add schema's to the user search path how would it know which table I was referring to if two schema's have the same table name. although, maybe I'm reading to much into this. Any insights or words of wisdom would be greatly appreciated!

• Understanding the singleton class when aliasing a instance method

  - by Backo

  I am using Ruby 1.9.2 and the Ruby on Rails v3.2.2 gem. I am trying to learn Metaprogramming "the right way" and at this time I am aliasing an instance method in the included do ... end block provided by the RoR ActiveSupport::Concern module: module MyModule extend ActiveSupport::Concern included do # Builds the instance method name. my_method_name = build_method_name.to_sym # => :my_method # Defines the :my_method instance method in the including class of MyModule. define_singleton_method(my_method_name) do |*args| # ... end # Aliases the :my_method instance method in the including class of MyModule. singleton_class = class << self; self end singleton_class.send(:alias_method, :my_new_method, my_method_name) end end "Newbiely" speaking, with a search on the Web I came up with the singleton_class = class << self; self end statement and I used that (instead of the class << self ... end block) in order to scope the my_method_name variable, making the aliasing generated dynamically. I would like to understand exactly why and how the singleton_class works in the above code and if there is a better way (maybe, a more maintainable and performant one) to implement the same (aliasing, defining the singleton method and so on), but "the right way" since I think it isn't so.

• Binding of JText fields value to Info Class

  - by Faizan Ahmed

  Is there any way to automatic binding of Swing JTextFields to Info Class. e.g private JTextField receiptId; private JTextField Id; public class Info { private string receiptId; private String id; // Getters and Setters } Is there any way when I entered values from Swing page then automatically values bind with my Info class? After that I can pass my Info object to other classes instead of sending all Text Fields.

• Jquery / CSS – addClass to first:p of multiple div with specified class

  - by j-man86

  Hello, I'm using (trying to use) jQuery to add a class to the first paragraph of every div with class of ".djBio" My problem is that it's only adding the class to the first div.djBio, not all divs with that class. Here's the code. I am also using the fancy letter jquery plugin to add the drop cap to the first paragraph (which also is only applying to the first div.djBio, not all) jQuery(function( $ ){ $('.servicesContent p:first, .about-usContent p:first, .djBio p:first').fancyletter().addClass('firstP'); }); Thanks so much for your help!

• How do you resolve the common collsision between type name and object name?

  - by Catskul

  Since the convention is to capitalize the first letter of public properties, the old c++ convention of initial capital for type names, and initial lowercase for non-type names does not prevent the classic name collision class FooManager { public BarManager BarManager { get; set; } // Feels very wrong. // Recommended naming convention? public int DoIt() { return Foo.Blarb + Foo.StaticBlarb; // 1st and 2nd Foo are two // different symbols } } class BarManager { public int Blarb { get; set; } public static int StaticBlarb { get; set; } } It seems to compile, but feels so wrong. Is there a recommend naming convention to avoid this?

• Scala: getting the name of the class the trait is mixed in

  - by Alexey Romanov

  Given an instance of a class, we can obviously return its name: trait MixedInClassDiscovery { val className = this.getClass.getName } class AClass extends MixedInClassDiscovery { ... this.className // returns "AClass" ... } But this way uses reflection, once for every instance of AClass. Can the same be done once for every class, instead? One solution which comes to mind is to mix it into companion objects instead of classes themselves.

• How to write different implicit rules for different file names for GNU Make

  - by anupamsr

  Hi! I have a directory in which I keep adding different C++ source files, and generic Makefile to compile them. This is the content of the Makefile: .PHONY: all clean CXXFLAGS = -pipe -Wall -Wextra -Weffc++ -pedantic -ggdb SRCS = $(wildcard *.cxx) OBJS = $(patsubst %.cxx,%.out,$(SRCS)) all: $(OBJS) clean: rm -fv $(OBJS) %.out: %.cxx $(CXX) $(CXXFLAGS) $^ -o $@ NOTE: As is obvious from above, I am using *.out for executable file extensions (and not for object file). Also, there are some files which are compiled together: g++ file_main.cxx file.cxx -o file_main.out To compile such files, until now I have been adding explicit rules in the Makefile: file_main.out: file_main.cxx file.cxx file.out: file_main.out @echo "Skipping $@" But now my Makefile has a lot of explicit rules, and I would like to replace them with a simpler implicit rule. Any idea how to do it?

• Producing dynamically generated range names in Excel using c#

  What is the best way to produce several tables of unknown size on the same worksheet? Values will be pulled from an oracle database and are used as values on several tables. Is it possible to create dynamic named ranges or is some other method desirable? I have some experience with c# but do not have access to VSTO 2005. Any help or suggestions would be greatly appreciated. I am willing to explain the problem further if requested.

• How to I reference a pointer from a different class

  - by Justagruvn

  Hey team of awesomeness!, (Iphone Objective-C question) First off, I despise singletons with a passion. Though I should probably be trying to use one, I just dont want to. I want to create a data class (that is instantiated only once by a view controller on loading), and then using a different class, message the crap out of that data instance until it is brimming with so much data, it smiles. So, how do i do that? I made a pointer to the instance of the data class when I instantiated it. I'm now over in a separate view controller, action occurs, and I want to update the initial data object. I think I need to reference that object by way of pointer, but I have no idea how to do that. yes I've set properties and getters and setters, which seem to work, but only in the initial view controller class. Peace Love applesauce.

• class method as hash value

  - by demas

  I have this working code: class Server def handle(&block) @block = block end def do @block.call end end class Client def initialize @server = Server.new @server.handle { action } end def action puts "some" end def call_server @server.do end end client = Client.new client.call_server My Server will handle more then one action so I want to change code such way: class Server def handle(options) @block = options[:on_filter] end def do @block.call end end class Client def initialize @server = Server.new my_hash = { :on_filter => action } @server.handle(my_hash) end def action puts "some" end def call_server @server.do end end client = Client.new client.call_server It is incorrect code because action() method calls on create my_hash, but if I try to modify code to: my_hash = { :on_filter => { action } } i get error message. Is it possible to create hash with methods as hash values ?
