filesystemwatcher

问题 I am trying to monitor a directory for new files in it with the FileSystemWatcher Class. My Problem is that the event doesn't get triggered. My watcher class is: public class Filewatcher { private FileSystemWatcher watcher; public Filewatcher(string path, string filefilter) { this.watcher = new FileSystemWatcher(); this.watcher.Path = path; this.watcher.NotifyFilter = NotifyFilters.FileName; //| NotifyFilters.LastWrite | NotifyFilters.LastAccess this.watcher.Filter = filefilter; this.watcher

问题 I'm trying to implement a file watcher that will raise an event if the file content was changed. The problem that once the file I am watching was modified, I am getting 2 events. (I want to get it only once) _automationStatusWatcher = new FileSystemWatcher(fileInfo.Directory.FullName, fileInfo.Name); _automationStatusWatcher.NotifyFilter = NotifyFilters.LastWrite; _automationStatusWatcher.Changed += OnAutomationStatusChanged; _automationStatusWatcher.EnableRaisingEvents = true; The file that

问题 Using FileSystemWatcher, is there a way to dispose of instances of event listeners after an event has fired? My program basically listens for the creation of a batch.complete.xml file in newly created folders. Once the program detects that the file has been created there is no need to continue listening in this folder. My program looks like this: public static void watchxmlfile(batchfolderpath){ var deliverycompletewatcher = new FileSystemWatcher(); deliverycompletewatcher.Path =

问题 I'm doing a project in a course at my university on distributed systems. I'm planning on creating something similar to Dropbox ( getdropbox.com ), but with some sort of non-centralized peer-to-peer twist to it. For this i need some method of detecting change in a directory structure. How do you think Dropbox do this? Their implementation works remarkably well. I'm wonder if they use FileSystemWatcher from the win32 api on windows, and something similar and platform dependent on Linux and Mac.

问题 You know the feature for example, you opened C:\test.txt if you also have the same file in another editor, and you edit it there, when you return, the app will prompt that the file has changed, whether you want to update it. How do I check if the file has been updated? UPDATE Asked a sister question "Using FileSystemWatcher to watch for changes to files" 回答1: You could use a FileSystemWatcher to get notifications from the file system. 回答2: Either use FileSystemWatcher (preferred) or compare

问题 When switching back to a file open in PyCharm after modifying it with another program, PyCharm doesn't immediately pop-up a message asking whether you want to reload the file from disk or stick to the version in your memory (unlike other editors I've become used to). All it does is shows a little bar on the top with a tiny reload button; the popup message doesn't display until you try to save the file (by which time it's too late). I researched a bit; but couldn't find a switch. How can I set

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 For some reason, my FileSystemWatcher is not firing any events whatsoever. I want to know any time a new file is created, deleted or renamed in my directory. _myFolderPath is being set correctly, I have checked. Here is my current code: public void Setup() { var fileSystemWatcher = new FileSystemWatcher(_myFolderPath); fileSystemWatcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite | NotifyFilters.FileName | NotifyFilters.DirectoryName; fileSystemWatcher.Changed +=

问题 I'm trying to reproduce a console application which watches a folder and any new additions of documents to the folder are to be Indexed to ES . It is working fine If I move/add 3-4 documents at a time and able to index. But if I move around 30 documents at a time, It is not indexing all the documents, instead indexing only one. But If I run the code with break points , then even 30 documents are also getting indexed. Can some one help me in solving this. static void OnCreated(object sender,

问题 I have the below code to detect the creation of a new file and grab a copy of it. $folder = '\\server\share\monitor_me\' $filter = '*.*' $copyToFolder = 'C:\temp\capture\' $fsw = New-Object IO.FileSystemWatcher $folder, $filter -Property @{IncludeSubdirectories = $true;NotifyFilter = [IO.NotifyFilters]'FileName, LastWrite'} #protection from previous runs unregister-event -SourceIdentifier FileCreated -ErrorAction SilentlyContinue Register-ObjectEvent $fsw Created -SourceIdentifier FileCreated
