I'm currently styling a Silverlight combobox. The designer wants the combobox to turn black on "pressed", a state that is not supported by the combobox itself, but is available on the togglebutton ("DropDownToggle") within the combobox. So I edit the template for the togglebutton, and make it black on "pressed". No problem. The problem ...
Hello, I have a working solution in java using a classic state design pattern and facing some difficulties translating it to ruby. I am new in ruby, but the diffuclty I believe lies in the differences on how patterns can be implemented in dynamic languages. My interface is describing the actions the model can execute in every state: p...
How do I combine: button.modify_bg(gtk.STATE_NORMAL, gtk.gdk.color_parse("Green")) button.modify_bg(gtk.STATE_ACTIVE, gtk.gdk.color_parse("Green")) button.modify_bg(gtk.STATE_SELECTED, gtk.gdk.color_parse("Green")) etc. Into a one-liner wildcard covering all of the possible states (See Doc) ...
I was trying to find out which Entity Framework objects, if any, remain live after the end of an HTTP request that is being handled by ASP .Net? i.e. Does an ASP .Net application benefit from any of the Entity Framework caching mechanisms across different requests? This article describes the operations that are occurring under the hood...
I just read an article that describes how HttpApplicationState has AcquireRead() / AcquireWrite() functions to manage concurrent access. It continues to explain, that in some conditions however we need to use an explict Lock() and Unlock() on the Application object to avoid a Race condition. I am unable to understand why a race conditi...
I'm using a standard GridView with a LinqDataSource. The user can sort and page through the grid using the stock standard stuff. Searching criteria (WhereParameters) can also be used to filter the results. This works great, but the state is obviously lost whenever navigating away from the page. So a generic mechanism of capturing the So...
A very flowery title indeed. I have a PHP web application that is in the form of a web based wizard. A user can run through the wizard and select options, run process (DB queries) etc. They can go backwards and forwards and run process again and again. I am trying to work out how to best save the state of what users do/did, what proces...
Hi guys, I want to implement functionality that give possibility switch tabItems (TabItem1,TabItem2,TabItem3), when user click button "next" on the Form. And for that reason I'd like to use State Machine Pattern. These things I've already implemented, but I have no clue, is it right or not?: public abstract class State { #...
Example: class UserStorage { public function addUser(User $user) { //saves to db } } class User { public function setName($name); } What if I add a user to the user storage and later change that user object? In this case you might argue that user objects only should be stored on __destruct. But sometimes this isn't an option ...
Hey guys, I'm trying to work out how to use the CrmService to close a Task in MS CRM 4.0 I've tried to use the SetStateTaskRequest to set a Task's state and status to TaskState.Completed and 5. I also tried TaskState.Completed and -1, but no dice there either. Either way, I only receive the ever-helpful "Server was unable to process r...
What are three ways in which web applications can provide a stateful experience for the user?(using http) I know Sessions and Cookies are two of them, but don't know a third (database??) Yes a question from a lecture. ...
I want the user to be able to save the state of their grid, so that their sort options, column widths (and order) are preserved for the duration of their visit. Does anyone know of a way of doing this? I have noticed that the dhtmlXGrid provides a cookie interface for doing this: http://www.dhtmlx.com/dhxdocs/doku.php?id=dhtmlxgrid%3Acoo...
Hi, I'm developing a Silverlight 3 Application which I want to connect to a webservice with a provided .dll or with SOAP. But the .dll is not suited for Silverlight so I can not do that. And I can't access the SOAP service because of cross-domain issues (I do not host it so a clientpolicy xml will not do). So my solution is the include...
I recently made a recommendation to one of my colleagues stating that on our current project (C#) "services should be stateless and therefore static". My colleague agreed and indicated that in our project the services are (and should be) indeed stateless. However my colleague disagreed that static implies no state and that stateless sh...
In .NET Remoting, Activator.GetObject method has a state parameter. What is the purpose of this state param? Can I retrieve its value from server side? mdsn didn't help much. What I'd like to do: Client side: ChannelServices.RegisterChannel(new TcpChannel(0)); object obj = Activator.GetObject(typeof(MyObj), "tcp://serverName:1234/Remot...

There is a talk here by Stefan Tilkov, where he is describing REST architecture at its core. I haven't watched all of it, but in the portion where he talks about the 5 Principles of REST (slides 12-19) he mentions maintaining state through the resource (i.e. -- the URI). His example is a shopping cart. Usually the state of your shopping ...

The popup simply asks for an email address and then the application is enabled showing the email address in a label component. However, when I try to access the email ...

I am in the middle of solving a problem where I think it's best suited for a decorator and a state pattern. The high level setting is something like a sandwich maker and dispenser, where I have a set amount of ingredients and a few different types of sadnwiches i can make. Each ingedient has a cost associated with it. The client would be...
