polling

I am learning Unity with C# and studying the GUI Button. I found the following statement in Unity documentation: "This means that your OnGUI implementation might be called several times per frame (one call per event). " using UnityEngine; using System.Collections; public class ExampleClass : MonoBehaviour { void OnGUI() { if (GUI.Button(new Rect(10, 10, 150, 100), "I am a button")) print("You clicked the button!"); } } My questions are: 1) The above "if" statement will keep detecting the condition until it is true. It should be called polling input. Why does the above code use polling input

I'm trying to implement an automatic refresh on a List of components in a Vaadin view. The list gets its contents from a database. I can refresh the list with a button, that is already implemented. However, I would like to know what is the simplest way to make it so, that this refresh event, that I already have, would automatically refresh in 5 minute (300 000 milliseconds) intervals? Here's what I tried and it keeps refreshing even after I exit the view so it doesn't really work. I'd like the refresh to happen in 5 minute intervals only while that certain view is being shown.

Requirement: User scans multiple job numbers, for each job number , I need to call one API and get the total job details and show it in a table below the scanned text box. User don't want to wait until API call finishes. He will scan continuously irrespective of details came or not.

And what is interesting the issue is like known Silverlight 4 bug when using MaxMessagesPerPoll duplex mode and solution is described here and here but I'm using SingleMessagePerPoll mode.

I am implementing a low weight application where I have to open and read the /proc/pid or tid/task/stat details very often. If the application is multithreaded I have to read more stat files. So opening, reading and closing makes my monitoring application really slow. Is there a solution to avoid opening the file repeatedly and still able to read the updated content? I ran the following experiment but I don't see success. I change the data in "test.txt" but the new data is not read. Is it because the file is not updated in memory? What happens when i modify and save "test.txt"? #include <stdio
