state

I have a class called "PropertyFeature" which simply contains PropertyFeatureID and Description. It's a proper model created through LINQ to SQL mapped to an SQL Server database table. An example instance/row would be: PropertyFeatureID: 2 Description: "Swimming Pool" The number of rows (PropertyFeatures) can of course grow and shrink, and so I want to dynamically render a list of checkboxes so that the user can select any of them. I can dynamically render the Checkboxes easily enough, with something like: <%foreach (var Feature in (ViewData["Features"] as IEnumerable<MySolution.Models

Regarding iPad events, how to determine if/when the iPad is changing from an awake state to a standby state? What I would like to do is put my Mobile-Safari web app in a locked state whenever the iPad becomes inactive/standby and ask for a PIN when it becomes awake again. I agree that there really ought to be some signal you can hook on to to know when an application goes to sleep and when it wakes up, but you should be able to figure out when Safari wakes up indirectly. When the webview goes into the background, Safari puts everything in it to sleep. It pauses any video, defers network

The users of my web application may have more than one browser window open and pointed to the same page. I would like the state of certain things in the page (loaded via ajax) to be retained across postbacks. I can either store in a cookie or on my server. Either way, I can't think of how I can distinguish each window. For example, say user Bob has two browser windows open to the ListOfSomething page. Each list has a LoadedPageNumber attribute which I need to persist. Otherwise users always end up on page 1 when they refresh. Bob might have loaded browser window 1 and pointed it to page 5 and

I've be fiddling around with ui-router today in trying to better understand the scaffolding in Ionic and one thing that I noticed was that they give the abstracted state of "tabs" a url. The only times I've ever used abstract states, I used an empty string as the url and I notice that if I've ever accidentally attempted to navigate to an abstracted state (as opposed to the child state) I get the error: Cannot transition to abstract state '[insertAbstractStateHere]' edit: "Moreover, in experimenting, when I try to assign a url to my abstract state (outside of Ionic) and still render the nested

What are the differences between the Strategy design pattern and the State design pattern? I was going through quite a few articles on the web but could not make out the difference clearly. Can someone please explain the difference in layman's terms? Honestly, the two patterns are pretty similar in practice, and the defining difference between them tends to vary depending on who you ask. Some popular choices are: States store a reference to the context object that contains them. Strategies do not. States are allowed to replace themselves (IE: to change the state of the context object to

I am attempting to use the 'File' function in ActionScript 3 to save the following information: I have varying draggable display objects in the scene, the amount and type can vary. I want to save the amount and their position and then load them back in a future session. I am struggling to use File to save anything, I have searched the Adobe documentation and cannot get my head round how to use it. I have not yet developed any code using it. Any help would be appreciated. Thank you. You are trying to write a DisplayObject into the file directly, this is prevented by Flash engine due to the way

When I move from one view controller to another, the switch on the first controller resets itself and does not retain its state. How can I make it save its state when come back to it after viewing other controllers? And how do I make it save its state after closing the app. I have looked at the various stackOverflow questions and responses and the apple documentation, but nothing seems to work. Here is my class for the View Controller that has the switch. class Days: UIViewController { @IBOutlet weak var switchButton: UISwitch! var switchState = true let switchKey = "switchState" override func

I have a list of elements and I wish to update them: from this: ["Off","Off","Off","Off"] to this: ["Off","Off","On","Off"] As I am somewhat new to Haskell, I have been using (x:xs)!!y to extract and update individual components using the function: replace y z [] = [] replace y z (x:xs) | x==y = z:replace y z xs | otherwise = x:replace y z xs and then entering the following in ghci: (replace "Off" "On" ["Off",'Off","Off","Off"]) !! 2 I get the following: "On" I seem to be able to extract and convert elements of a list but I can't seem to get a list up with the single element converted. Any
