filesystemwatcher

问题 When I try to debug a Python file with PyCharm Community Edition, the IDE opens a new tab (highlighted in yellow) despite me having that file open already in a pre-existing tab. Sometimes, that duplicate tab contains an older version of the file without changes that I just made. Although both of the above are different issues and don't always occur together, I suspect there's a common cause. How can I disable these non-intuitive behaviours? 回答1: The problem is apparently similar to the cause

问题 I am getting an exception System.IO.Internal.BufferOverflowException when I am trying to monitor a folder on network path(DFS - Distributed File System): To many changes at once . It works fine when FileSystemWatcher is monitoring local/network path that don't use this filesystem. I am able to get an event from 1000 + files on local path and I am not getting BufferOverflow exception, however when I am copying file to folder that is on DFS I am not even able to get an event from one(To clarify

问题 I'm looking for a cross platform file system watcher, similar to the FileSystemWatcher class in .NET. As it's for a daemon/service, I'm not keen on Qt's QFileSystemWatcher. I'd really like to avoid it as I don't want to have a dependency on Qt as my program is going to be a daemon. I've also seen a proposal for such a class to be included in Boost, but as far as I know such a class has not yet been included. Is there a cross platform C++ file system watcher? 回答1: Qt is divided into modules,

问题 I'm building a program that keeps track of a directory and adds an entry to an mysql database whenever a new file has been created in the directory. I'll show the code for the FileSystemWatcher, the storage instance is an mysql class: FileSystemWatcher watcher = new FileSystemWatcher { Path = directoryToWatch, IncludeSubdirectories = true, NotifyFilter = NotifyFilters.Attributes | NotifyFilters.DirectoryName | NotifyFilters.FileName, EnableRaisingEvents = true, Filter = "*.*" }; watcher

问题 FileSystemWatcher does not work properly when many files are added to the directory at the same time... The Watcher simply doesn't find all the files in the directory - only if the files are placed in the folder one by one - not if lots of files are copied to the folder at the same time... Is the creation of Threads the solution to the problem or is there another way to handle the problem ? 回答1: The documentation on that class details that problem: The Windows operating system notifies your

问题 I have to create a program that monitors changes in file size. I already made a simple windows service and filesystemwatcher so I am now familiar w/ the concept. I also made a code that checks for the filesize (made it in a form button)but haven't yet implemented in my filesystemwatcher. How do I create a windows service that has a filewatcher that monitors the file size? Do I have to put a filesystemwatcher inside the windows service and call the watcher via the OnStart method? 回答1: If you

问题 I'm looking for a reliable way of looking for changes in a directory. I have tried using the FileSystemWatcher, but it's rather inaccurate when many small files are created, changed or deleted. It misses about 1 or 2 % of the files in my tests. That is quite a lot when you are adding or changing thousands of files rapidly. I have tried polling for changes at different intervals 500 ms, 2000 ms etc. In this case I get too many hits. That might have something to do with the resolution of

问题 is it possible to get the name of the process that caused the change in the filesystem? i want to do this programmatically [ie, i can't use any external 3rd party tools like handle] any ideas? 回答1: The OS doesn't provide such information. You would need a file system filter driver for fine-grain control over changes made on the file system. 来源： https://stackoverflow.com/questions/6615999/filesystemwatcher-how-to-know-which-process-made-the-change

问题 When there is a big file moved into the watched folder,it raises created event even before the file is copied fully. Copying such files within the created event causes 'file being used by another process' error. I used a thread that tries to copy the file until it is allowed to do so.but i am still not satisfied. Can we configure FileSystemWatcher such that the created event is raised only after the file is fully copied?thanks. 回答1: The documentation for the FileSystemWatcher class

问题 I am trying to get a notification when a file is updated on disk. I am interested in getting this notifications as soon as a flush occurs, yet, it seems that the FileSystemWatcher would only send an event when the stream opens or closes. In the code below I am writing to a file and repeatedly flush the buffer to the disk. Yet, the FileSystemWatcher only notified me once in the beginning of the writes and once when they end. Is there another way to get these notifications? Or should I use
