问题 i've recently come across a producer/consumer pattern c# implementation. it's very simple and (for me at least) very elegant. it seems to have been devised around 2006, so i was wondering if this implementation is - safe - still applicable Code is below (original code was referenced at http://bytes.com/topic/net/answers/575276-producer-consumer#post2251375) using System; using System.Collections; using System.Threading; public class Test { static ProducerConsumer queue; static void Main() {

问题 Is it possible to write an application in Java that runs in the tray and when a certain application is launched, it can detect it? I want to do this for certain programs to find out how long I use them for a weekly basis. I'm new to Java, so I don't know if Java is even the best language for this, or if it has the proper access to the operating system to do this. 回答1: Java in itself does not have much integration into system-specific features (nor do most other general-purpose languages). If

问题 I feel perturbed, but I don't understand the measurement Azure uses for Network In/Out and a few other things. On Azure portal -> my VM -> Metrics -> [Host] Network In/Out, it says that it is measured in bytes, but then it also draws graph over time. If it were plain, bytes, it should be cumulative and therefore grow indefinitely, but it isn't, therefore I am inclined to believe it is measured per second or something like that. But Azure docs claim that it is bytes and not bytes per second

问题 My project uses spring and spring-dm for bean/service configuration. When I try to import an old project which also use spring for DI, bean will not be created. An example to make clear, I first define a url-alias in spring-appContext.xml <bean name="xxxx" class="XRegistry" init-method="init"> <property name="webRoot" value="/WebContent"></property> <property name="alias" value="/test"></property> <property name="cAliasPattern" value="/test/*.do" /> <property name="conConfigFile" value="ddd

问题 I am building a prototype drip monitor for a brain shunt. It will monitor the drips and report whatever data I need. The problem is I'm just building the device. A person who knows nothing about Arduinos or code is using it. Is there a way or program to display and/or save data to a file such that a person could just plug the Arduino in and not bother the the IDE or any code? Thanks for the help! 回答1: As noted in the comments, there are many ways to do this depending on budget and other

问题 I'm trying to use FSEvents in my sandboxed app to monitor some directories. I implemented the following class: @implementation SNTracker - (id)initWithPaths:(NSArray *)paths { self=[super init]; if (self) { trackedPaths=paths; CFTimeInterval latency=1.0; FSEventStreamContext context={0,(__bridge void *)self,NULL,NULL,NULL}; FSEventStreamRef eeventStream=FSEventStreamCreate(kCFAllocatorDefault,&callback,&context,(__bridge CFArrayRef)trackedPaths,kFSEventStreamEventIdSinceNow,latency

问题 I need to unzip a .ZIP archive. I already know how to unzip it, but it is a huge file and takes some time to extract. How would I print the percentage complete for the extraction? I would like something like this: Extracting File 1% Complete 2% Complete etc, etc 回答1: here an example that you can start with, it's not optimized: import zipfile zf = zipfile.ZipFile('test.zip') uncompress_size = sum((file.file_size for file in zf.infolist())) extracted_size = 0 for file in zf.infolist():

问题 I am writing a small C# application to identify which type of display connect to pc A Monitor A TV screen A projector I try to do with Screen.AllScreens EnumDisplayDevices() but it does not help anything. When I use var mbs = new ManagementObjectSearcher("Select * From CIM_LogicalDevice"); ManagementObjectCollection mbsList = mbs.Get(); I can get device id: DISPLAY\OTMFB0E\4&9C24ACE&0&UID16843008 DISPLAY\DELD058\4&9C24ACE&0&UID50725632 But there is not any value which is used to identify
