• Multiple Keybinding to a single command

  - by Veer

  My window has just a listview. This facilitates the users to incremental search the db. Since the design does not have a textbox, i've to globally handle the keys. I think it could be achieved by keybinding. But how can i handle all the keys and associate it to a single command. Also suggest me other methods if any.

  - by letseatfood

  I am interested in implementing version control for the first time. I am starting to amass custom libraries and would like to know what methods you would recommend for implementing version control on a Windows Vista OS. I also have an Ubuntu server setup.

• I'm new to OOP/PHP. What's the practicality of visibility and extensibility in classes?

  - by marcdev

  I'm obviously brand new to these concepts. I just don't understand why you would limit access to properties or methods. It seems that you would just write the code according to intended results. Why would you create a private method instead of simply not calling that method? Is it for iterative object creation (if I'm stating that correctly), a multiple developer situation (don't mess up other people's work), or just so you don't mess up your own work accidentally?

• What is the canonical way to return a json object in asp.net webforms programming?

  - by Joe

  In ASP.Net MVC action methods can return json objects simply by returning something like so: JSon([whatever]) How do I return a JSon representation of say List<String> with webforms either through a service or through a method in the code behind of an aspx page? This seems incredibly confusing compared to ASP.Net MVC.

• Storing GenericForeignKey content_type in another model?

  - by slypete

  I have a typical definition/instance situation in my data modeling. I'm trying to store the content_type of a GenericForeignKey in another model (the definition model) like so: class IndicatorFieldInstance(models.Model): definition = models.ForeignKey(IndicatorField) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey(definition.content_type, 'object_id') indicator_instance = models.ForeignKey(IndicatorInstance) I've also tried it like this: content_object = generic.GenericForeignKey('definition__content_type', 'object_id') Neither of these methods seem to work. Is it possible to achieve this? For reference, here's the definition model: class IndicatorField(models.Model): name = models.CharField(max_length='255') content_type = models.ForeignKey(ContentType) indicator = models.ForeignKey(Indicator) Thanks, Pete

• GWT: stange import collision error in visualisation api

  - by parag_

  hi, I'm attempting to add two charts to a gwt page using the visualization api, but for some strange and inexplicable reason, eclipse claims that the following two imports are colliding - which makes no sense to me. In the methods where i am calling them, I have even tried using the fully qualified names, but that doesnt seem to help either. Any idea what may be going on ? import com.google.gwt.visualization.client.visualizations.Table.Options; import com.google.gwt.visualization.client.visualizations.LineChart.Options;

• avoiding the tedium of optional parameters

  - by Kyle

  If I have a constructor with say 2 required parameters and 4 optional parameters, how can I avoid writing 16 constructors or even the 10 or so constructors I'd have to write if I used default parameters (which I don't like because it's poor self-documentation)? Are there any idioms or methods using templates I can use to make it less tedious? (And easier to maintain?)

• How to catch an exception and email information about it in liferay portlet

  - by heikkim

  I have a custom portlet made for liferay and sometimes it throws an exception. Why it throws exceptions is irrelevant. How to catch exceptions thrown by portlet handler methods in order to email information about them? I know I could do try catching on every handler method but it would be a much more elegant and cleaner solution to catch the exception on a higher level and just email some information about the error. I'm using Spring Portlet MVC, so i got all spring-related niceties at hand.

• Compiling .xsl files into .class files

  - by Alex Ciminian

  I'm currently working on a Java web project (Spring) which involves heavy use of xsl transformations. The stylesheets seldom change, so they are currently cached. I was thinking of improving performance by compiling the xsl-s into class files so they wouldn't have to be interpreted on each request. I'm new to Java, so I don't really know the ecosystem that well. What's the best way of doing this (libraries, methods etc.)? Thanks, Alex

• How can I make a single WCF method ConcurrencyMode.Multiple when service is ConcurencyMode.Single

  - by Michael Hedgpeth

  I have a service which is defined as ConcurrencyMode.Single: [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Single, UseSynchronizationContext = false, InstanceContextMode = InstanceContextMode.PerSession, IncludeExceptionDetailInFaults = true)] public class MyService : IMyService This service provides a method to tell the client what it's currently working on: [OperationContract] string GetCurrentTaskDescription(); Is there a way to make this particular method allowable while another long-running task is running where all other methods still follow the single-threaded concurrency model?

• Is using Clone() a bad programming practice if doing on heavily loaded objects?

  - by user301292

  We have a class that is more like a template (with lot of properties and overridden methods). I need to make many objects of that class type. Can I use clone() to create objects with specific settings if I have one object created? I know I need to override the Clone method. Is the performance going to take a hit by using Clone()?

• Sorting function/variables in an object by name

  - by sissonb

  I was wondering if PHPStorm by Jetbrains has a tool to sort the methods in my JavaScript object by name. If not are there any other tools that can do this for me? Ext.regController("dashboard", { goToShoppingCart:function() { Ext.dispatch({ controller:"shoppingCart", action:"loadCart" }); }, goToDashboard:function() {}, goToContact:function() {} } ); to Ext.regController("dashboard", { goToContact:function() {}, goToDashboard:function() {}, goToShoppingCart:function() { Ext.dispatch({ controller:"shoppingCart", action:"loadCart" }); } } ); This is only for organization. Thanks
