    - by ak
    I have a package with a few modules, each module has a class (or a few classes) defined within it. I need to get the list of all modules within the package. Is there an API for this in python?

  • How to make some functions of a class as private for third level of inheritance.

    - by Shantanu Gupta
    I have created a class say A which has some functions defined as protected. Now Class B inherits A and class C inherits B. Class A has private default constructor and protected parameterized constructor. I want Class B to be able to access all the protected functions defined in Class A but class C can have access on some of the functions only not all the functions and class C is inheriting class B. How can I restrict access to some of the functions of Class A from Class C ? Class A { private A(){} protected A(int ){} protected calc(){} protected allow(){} } Class B : A {} // calc() and allow() should be accessible here CLass C:B { // calc() should not be accessible here but allow() should be accessible here. }

  • Vimrc: how to reuse code and definitions for differnt file types?

    - by sixtyfootersdude
    I have defined my own file types using vim. For example I have: .classNotes .reportJotNotes .homework These file types are defined in .vim files: ~/.vim/syntax/homework.vim ~/.vim/syntax/reportJotNotes.vim ~/.vim/syntax/homework.vim Many of these things have several of the same code in them. Ie they all have this for titles: syn region JakeTitle start=+=== + end=+===+ oneline highlight JakeTitle ctermbg=black ctermfg=Yellow syn region JakeMasterTitle start=+==== + end=+====+ oneline highlight JakeMasterTitle cterm=bold term=bold ctermbg=black ctermfg=LightBlue Instead of having this in all three .vim files I would rather have it in one file and then in each file could source it. How can I do this?

  • Problem in databinding a dictionary in ListView combo-box column.

    - by Ashish Ashu
    I have a listview of which itemsource is set to my custom collection, let's say MyCollection. The code below is not full code , it's just a code snippets to explain the problem. class Item : INotifyPropertyChanged { Options _options; public Options OptionProp { get { return _options; } set { _options = value; OnPropertyChanged ("OptionProp");} } string _Name; public string NameProp { get { return _Name; } set { _Name = value; OnPropertyChanged ("NameProp");} } } class Options : Dictionary<string,string> { public Options() { this.Clear(); this.Add("One" , "1" ); this.Add("Two" , "2" ); this.Add("Three" , "3" ); } } MyCollection in my viewModel class viewModel { ObservableCollection<Item> **MyCollection**; KeyValuePair<sting,string> **SelectedOption**; } The listview Item Source is set to my MyCollection. <ListView ItemSource = MyCollectoin> I Listview contains two columns of which I have defined a datatemplats in the listview. First column is a combo-box of which Itemsource is set to Options ( defined above ) Second column is a simple textblock to display Name. Problem 1. I have defined a datatemplate for first column in which I have a combo box , I have set the Itemsource =**MyCollection** and SelectedItem = SelectedOption of the combo-box. User can perform following operations in the listview: Add ( Add the row in the listview ) Move Up ( Move row up in the listview ) Move Down ( Move down the item in the listview ) .Now when I add the row in the listview , the combo-box selected index is always comes to -1 (first column). However the combo box contains options One, Two and Three. Also, I have initialized the SelectedOption to contain the first item, i:e One. problem 2. . Let suppose, I have added a single row in a listview and I have selected Option "one" in the combo box manually. Now when I perform Move Up or Move Down operations the selected index of a combo box is again set to -1. In the Move Up or Move Down operation , I am calling MoveUp and MoveDown methods of the Observable collection. Probelm 3 How to serialize the entire collection in XML. Since I can't serialize the Dictionary and KeyValue Pair. I have to restore the state of the listview.

  • Where is the appropriate place to define inflector rules in CakePHP 1.3?

    - by Daniel Wright
    In CakePHP 1.2, custom inflector rules could be defined in a file app/config/inflections.php. This file was removed in CakePHP 1.3. Instead, the documentation prescribes using the Inflector::rules function to load custom inflections. There's adequate documentation of how to define the custom inflections themselves, but the documentation gives no context—where to use Inflector::rules. Should any custom inflections be defined in the bootstrap.php script? At the top of applicable corresponding controllers? Somewhere else?

  • How to mark messages that are received by an java application using javax Mail Api?

    - by telebog
    I want to create an application that gets all e-mails from an e-mail account using imap. When I first run the application I get all mails, than if I run it again I want to mark the messages that was read before so I can receive only new messages. I found that Message Object contains Flags(System Flags and User defined flags), but I can't manage to set one user defined flag. It is possible to mark the messages received by my application on the e-mail account, or I have to retain all message ids and every time when I get messages from imap I have to compare their id with retained ids and get only the messages that has different ids?

  • NHibernate 'IdentifierGenerationException' on an Update trigger

    - by Jan Jongboom
    In my database I have an id column defined as [autonumber] [int] IDENTITY(1,1) NOT NULL which is mapped in my .hbm.xml like: <id name="Id" column="autonumber" type="int"> <generator class="identity" /> </id> When calling session.Save() updates are successful committed to the database. When adding a versioning trigger I however get the error this id generator generates Int64, Int32, Int16 of type IdentifierGenerationException. The trigger is defined as: ALTER TRIGGER [dbo].[CatchUpdates_NVM_FDK_Kenmerken] ON [dbo].[NVM_FDK_Kenmerken] INSTEAD OF UPDATE AS BEGIN SET NOCOUNT ON UPDATE NVM_FDK_Kenmerken SET idIsActive = 0 WHERE internalId IN (SELECT internalId FROM INSERTED) INSERT INTO dbo.NVM_FDK_Kenmerken ( vestigingNummer , internalId , someOtherColumns, dateInserted, idIsActive ) SELECT vestigingNummer, internalId, someOtherColumns, GETDATE(), 1 FROM INSERTED END What am I doing wrong here? When doing manual updates everything works just fine and as expected.

  • JavaScript in multiple files

    - by vijay.shad
    Hi, I Have created two JavaScript files.One file is "validators.js" and other is "UserValidations.js". Here is the code for validators.js function isBlankString(value) { if (value.replace(/\s/g, "") == "") { return true; } else { return false; } } In other js file I have defined function for validating user name like this. function validateUsername(element) { var username = element.value; if(value.replace(/\s/g, "") == ""){ //nothing to validate return; }else{ //validation logic } } Now as it is obvious i should have used isBlankString(value) method to check string length. But I am clue less about how can i use the function defined in other file?

  • Thin & Sinatra not taking port

    - by NekoNova
    I'm having problems settig up my application using Thin and Sinatra. I have created a development-config.ru file that contains the following settings: # This is a rack configuration file to fire up the Sinatra application. # This allows better control and configuration as we are using the modular # approach here for controlling our application. # # Extend the Ruby load path with the root of the API and the lib folder # so that we can automatically include all our own custom classes. This makes # the requiring of files a bit cleaner and easier to maintain. # This is basically what rails does as well. # We also store the root of the API in the ENV settings to ensure we have # always access to the root of the API when building paths. ENV['API_ROOT'] = File.dirname(__FILE__) $:.unshift ENV['API_ROOT'] $:.unshift File.expand_path(File.join(ENV['API_ROOT'], 'lib')) $:.unshift File.expand_path(File.join(ENV['API_ROOT'], 'db')) # Now we can require all the gems used for the entire API by simpling requiring # them here. We can also include the classes that we have defined inside the lib # folder. require 'rubygems' require 'bundler' # Run Bundler to setup our gems properly. This will install all the missing gems on # the system and ensure that the deployment environment is ready to run. Bundler.require # To make the loading easier for the application, we will now automatically load all # models that have been defined inside the lib folder. This ensures that we do not need # to load them anymore anywhere else in our application, as the models will be known to # ruby everywhere. Dir.glob(File.join(ENV['API_ROOT'], 'lib', '**', '*.rb')).each{|file| require file} # Now we will configure the Sinatra application so that we can fire up the entire API. # This requires some detailed settings like whether logging is allowed, the port to be # used and some folder locations. require 'sinatra' require 'app' set :logging, true set :dump_errors, true set :port, 3001 set :views, "#{ENV['API_ROOT']}/views" set :public_folder, "#{ENV['API_ROOT']}/public" set :environment, :test # Start up the Sinatra application with all the settings that we have defined. run App.new This is based upon the information I found on the Sinatra website. However, the problem is that I cannot get the application running on port 3001. If I use thin start -R development-config.ru it runs on port 3000. If I use rackup config-development.ru it runs on port 9696. However I never see Sinatra kick in or run over port 3000. My application looks like this: # Author : Arne De Herdt # Email : # This is the actuall application that will be running under Sinatra # to serve the requests for the billing middleware API. # We use the modular approach here to allow control when deploying # the application using Capistrano. require 'sinatra/base' require 'logger' require 'savon' require 'billcrux' class App < Sinatra::Base # This action responds to POST requests on the URI '/billcrux/register' # and is responsible for handeling registration requests with the # BillCrux payment system. # The post "/billcrux/register" do # do stuff end end Can someone tell me what I am doing wrong?

  • ASP.Net MVC 2 / EF 4 Reference Issue

    - by Eric J.
    My ASP.Net MVC 2 project references a Domain project where POCO business objects are defined and a Data project where EF 4 POCO persistence is implemented. Things were running well until I had a little fussiness with my version control provider (rollback to previous version left me with merge conflicts). Now, upon launching the MVC 2 project, I get a runtime error: The type 'System.Data.Objects.DataClasses.IEntityWithKey' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. However, every project references System.Data.Entity (same version). If I remove the reference to System.Data.Entity from the MVC 2 project, I get the same message as a compile-time error. I'm pretty sure something got messed up when I had the version control issue, but really not sure where to look for this one.

  • xcode - warning there's no getter/setter for property not even mentioned in the code!!

    - by alexeyndru
    I got the warning : property 'textField' requires method '-textField' to be defined - use @synthesize, @dynamic or provide a method implementation. Now, there is no such property defined in my project! More bizarre, if I just click save in Interface builder and build again, the build is successful - though, right on the line with '@end' the warning appears. Also weird: if I begin to write some code ..and then delete it just the way it was before writing it (maybe not code..anything) and then build&go the warning with the textField appears again. Could be a bug of sdk? What could be happening?

  • Does style="color: #FFF;" render as #F0F0F0 or #FFFFFF?

    - by Dolph Mathews
    When defining colors using "shorthand hexidecimal" (style="color: #FFF;"), is there a defined method for expanding the shorthand? (style="color: #F0F0F0;" or style="color: #FFFFFF;") Do all browsers use the same expansion method? Is this behavior by specification (if so, where is it defined)? Does the expansion method perhaps vary between CSS 1/2/3? I've observed that "most browsers" expand to #FFFFFF. Are there any other places where this shorthand notation is allowed, but the expansion method is different? I've always avoided using shorthand hex, because I've never known the answers to these questions...

  • How to write custom data to the TCP packet header options field with Java?

    - by snarkov
    As it is defined (see: http://www.freesoft.org/CIE/Course/Section4/8.htm) the TCP header has an 'Options' field. There are a couple of options already defined (see: www.iana.org/assignments/tcp-parameters/) but I want to come up with my very own. (For experimenting/research.) How can I get Java to write (and then read) some custom data to the options field? Bonus question: if it cannot be done with Java. what kind of application can do this? (No, I don't really feel like messing with some kernel-level TCP/IP stack implementation, I want to keep it app level.) Thanks!

  • How, exactly, does the double-stringize trick work?

    - by Peter Hosey
    At least some C preprocessors let you stringize the value of a macro, rather than its name, by passing it through one function-like macro to another that stringizes it: #define STR1(x) #x #define STR2(x) STR1(x) #define THE_ANSWER 42 #define THE_ANSWER_STR STR2(THE_ANSWER) /* "42" */ Example use cases here. This does work, at least in GCC and Clang (both with -std=c99), but I'm not sure how it works in C-standard terms. Is this behavior guaranteed by C99? If so, how does C99 guarantee it? If not, at what point does the behavior go from C-defined to GCC-defined?

  • ColdFusion static key/value list?

    - by richardtallent
    I have a database table that is a dictionary of defined terms -- key, value. I want to load the dictionary in the application scope from the database, and keep it there for performance (it doesn't change). I gather this is probably some sort of "struct," but I'm extremely new to ColdFusion (helping out another team). Then, I'd like to do some simple string replacement on some strings being output to the browser, looping through the defined terms and replacing the terms with some HTML to define the terms (a hover or a link, details to be worked out later, not important). Can anyone point me in the right direction of: How to define the stucture (if that is what I need for a key/value pair list) How to query at the application start-up and reuse the list properly The best way to do the string replacement

  • Python-How to call up a function from another module?

    - by user2691540
    I am making a project where I need several modules which are imported into one main module to make a pizza ordering service. Upon finishing this (to a working standard) I decided to re-code it so that the whole order is completed with one tkinter window, now instead of using input(), I use tkinter.Entry() etc. etc. To do this I had to use functions for each step so it is broken up nicely, e.g. the code asks if the user wants pickup or delivery, the user clicks a button which sets some variables and one of the buttons is then configured to say "continue" and the command leads to the next step of the pizza ordering process e.g. getting the name. The problem I have is that when I get past the last function of the first module the configured button has a command to go to a function in the second module, but it says that the command is not defined??? I have tried my way around this but cannot import the configured button variable into the next module, and anything else I tried gave no result, it simply doesn't go to the next module after the first module is done. I have made the main tkinter window in the main module and have it that it will mainloop after importing the other modules so shouldn't the function I want to call upon be defined? How can I get from one function to the next if the latter is in a seperate module? Is this possible or do I have to rethink my approach and if so how? Ok then, have made some more code to show what my problem is, this isn't what I am actually using but it's a lot shorter and has the same issue: this is the main module: import tkinter mainwindow = tkinter.Tk() # here i set the window to a certain size etc. import mod1 import mod2 mainwindow.mainloop() this is mod1: import tkinter def button1(): label.destroy() button1.destroy() button2.config(text = "continue", command = func2) def button2(): label.destroy() button1.destroy() button2.config(text = "continue", command = func2) label = tkinter.Label(text = "example label") button1 = tkinter.Button(text = "button1", command = button1) button2 = tkinter.Button(text = "button2", command = button2) label.pack() button1.pack() button2.pack() this is mod2: def func2(): button2.destroy() print ("haha it works...") I still get the problem that func2 is not defined? Thanks in advance

  • Question on ExtAudioFileRead and AudioBuffer for iPhone SDK

    - by backspacer
    I'm developing an iPhone app that uses the Extended Audio File Services. I try to use ExtAudioFileRead to read the audio file, and store the data in an AudioBufferList structure. AudioBufferList is defined as: struct AudioBufferList { UInt32 mNumberBuffers; AudioBuffer mBuffers[1]; }; typedef struct AudioBufferList AudioBufferList; and AudioBuffer is defined as struct AudioBuffer { UInt32 mNumberChannels; UInt32 mDataByteSize; void* mData; }; typedef struct AudioBuffer AudioBuffer; I want to manipulate the mData but I wonder what does the void* mean. Why is it void*? How can I decide what data type is actually stored in mData?

  • the characters except 0x00-0x7F are not been shown when converted to "UTF-8" from "ISO-8859-1"

    - by Mike.Huang
    I need to get a string from URL request of brower, and then create a text image by requested text. I know the default encoding of the Java net transmission is "ISO-8859-1", it can works normally with all characters what defined in "ISO-8859-1". But when I request a multi-byte Unicode character (e.g. chinese or something like ¤?), then I need to decode it by "UTF-8" from "ISO-8859-1". My codes like: String reslut = new String(requestString.getBytes("ISO-8859-1"), "UTF-8"); Everything is fine, but I found some characters in ISO-8859-1 are not been shown now, which characters are 0x80 - 0xFF(defined in" ISO-8859-1"), i.e. the characters except 0x00-0x7F are not been shown when converted to "UTF-8" from "ISO-8859-1" Any other method can solve this query?

  • Sending information back from delegate [iPhone]

    - by Andy
    I'm using NSXMLParser in my RootViewController.m file. NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:response_data]; [xmlParser setDelegate:self]; [xmlParser parse]; [xmlParser release]; I'm also implementing this method to add entries to a dictionary defined in RootViewController.m for later use: - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict However, I'd like to get more than one XML file and do different things when the file has finished; this sounds like I need to use external files as delegates. My question is: If I have the following implementation files (& their header files): RootViewController.m XMLDelegate1.m XMLDelegate2.m and set the ith NSXMLParser delegate to be XMLDelegatei.m, and get those files to return an NSDictionary that I can then add to the NSDictionary defined in RootViewController.m. I guess there are two methods of doing this: Use a method that I don't know about; or Use a better workflow I suspect it's 2, but hope it's 1. Thanks, Andy
