The following doesn't work for some reason: >>> class foo(object): ... @property ... @classmethod ... def bar(cls): ... return "asdf" ... >>> foo.bar <property object at 0x1da8d0> >>> foo.bar + '\n' Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unsupported operand type(s) fo...
Say you have a public method in Python whose primary purpose is to retrieve the value of an underlying data attribute (i.e. internal backing store). The method may have lazy evaluation logic, etc. A property is an example of such a method. Then it is natural to use the same name for the method and data attribute, except for an underscor...

We are using AutoMapper from Codeplex and for me the destination object has all the properties ending with 'Field', ie cityField and the source object has just city. I can use the below code to achieve but all of the properties are just suffixed with 'Field' and there are 20 properties. .ForMember(dest => dest.cityField, opt => opt.Map...
I'm having a bit of a brain melt at the moment where I have a WiX Combobox and when I change the selection I want to disable/enable other UI controls. <ComboBox Property="SQLAUTHTYPE"> <ListItem Value="WindowsAuth" Text="Windows Authentication" /> <ListItem Value="SqlAuth" Text="SQL Authentication" /> </ComboBox> That is w...
How can namedtuples be extended or subclassed with many additional @properties ? For a few, one can just write the text below; but there are many, so I'm looking for a generator or property factory. One way would be to generate text from _fields and exec it; another would be an add_fields with the same effect at runtime. (My @props are t...
Hi, I'm writing an Ant script and I like to call a macro multiple times using arguments from a list in a property file. The format of the property file is not important, it will be manually edited prior to Ant invocation. I'v been thinking about AntCall, SubAnt, RegExpMapper etc. but I'm simply not experienced enough in Ant to put it al...
I'm making a little program that will crawl my hard drive and present a list of file found in a given drive. My idea is to have a base File class, and implement Picture.cs, Video.cs and Document.cs classes inherited from the File.cs class. Here's my code: using System; using System.Collections.Generic; using System.Linq; using System....
I am Binding a TextBox with a property which is of type float. Everything works fine, I change the value in TextBox and it gets updated in property. The problem occurs when I make the TextBox blank, my property doesn't get updated, it is still having old value. Now I need to use converter in my binding to update property with default val...
I have a class LINE which contains two properties of type POINT. I would like POINT to be a component property. If LINE were to contain only 1 POINT, this would be no problem, but since it contains 2 POINTs I would think I needed to distinguish them (so a prefix or suffix can be applied to column names). I tried using the PropertyName a...
What's the best way to avoid (or control) the initialisation by the designer of a heavy custom property in .NET? Sometimes it is important to have a property set to something initially without that setting being acted upon when initially set. In the imaginary example below, I want to achieve the flexibility of having something like Upda...
Hi Guys, I need to know whether a public property (which has getter & setter) is changed. The property is in a simple class (no user control/component etc). Is there an elegant way to subscribe to some kind of event which notifies when property is changed? I tried to see what microsoft is doing in their Binding object (using reflector) a...
Hi, I'm working on an ant script. In this particular part, I need to get the current month, as well as the prior month. I was thinking something similar to <tstamp> <format property="thismonth" pattern="MMyy"/> <!-- 0210 by february 2010--> </tstamp> <!--I'd like to get 0110 (january 2010) here, but can't imagine how--> <property n...
I've seen many examples online and in this forum of how to create properties in Python with special getters and setters. However, I can't get the special getter and setter methods to execute, nor can I use the @property decorator to transform a property as readonly. I'm using Python 2.6.4 and here is my code. Different methods to use p...
There is a property, it's named ImageFullPath1 public string ImageFullPath1 {get; set; } I'm gonna fire an event whenever its value changed. I know I can beware of changing with INotifyPropertyChanged, but I wanna do it with events. I don't know how I should do it. Could you please guide me? Thanks. ...
I'm trying to create a property that will allow the setting of a last name based on a variety of inputs. The code that calls this is parsing a name field. In some instances it will have a single last name, in others, a array of last names that need to be concatenated. I want to keep my concatenation code in a single place to make mainten...
I've settled on the following style of creating properties (with a backing field): private _firstName; public string FirstName { get { return _firstName; } set { _firstName = value; } } Given that the name of the property is similar to the name of the backing field, I've improved the built in prop snippet to the following: <?...
I have a custom .net control like this: <myControl:control1 ID="dimDataSource" runat="server" SelectorType="red" EnableViewState="False" > </myControl:control1> I want to add a property that varies with the state of a standard html checkbox. (but if this can't be done, i'll add a .net checkbox) So here's a checkb...
Hi, Do you know any pointcut definition in spring.net to intercept only public property setter (standard properties and auto-implement properties)? Is there a way after this to remove some property by name (Id, Version...)? Is it possible possible to narrow pointcut to children of a certain base class (EntityBase)? As you can see i'm...
