cocoa touch - Trapping general UI activity within an iPhone app -


I'm developing an iPhone app that chooses the Internet web service. If the iPhone is idle in the dock running its application every time, once every 15 seconds, once every 15 seconds, the voting rate will be reduced. If the user starts to rotate the screen or turn around the UI, then I need to start the rate of voting again for 20 seconds.

Is there a universal top-level event handler, where I can net any user activity?

If I do not propose user activity to capture any push and pop activity in 4 main feature usage points such as the NAV controller bar of my productivity app.

In your application representative, -applicationDidBecomeActive and -applicationWillResignActive Apply.
To control all user activity, also apply your custom UIWindow sub-class and override - (zero) sendEvent: (UIEvent *) event there method: 

  - (zero) sendEvent: (UIEvent *) event {[Super send event: event]; ...}

Edit: You receive UIDeviceBatteryStateDidChangeNotification (from SDK 3.0) to get a notification when the device is plugged in ) Can also hear / unplugged in power

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
