configuring filesystemwatcher such that it raises created event only when the file is fully copied

断了今生、忘了曾经 提交于 2019-12-01 00:56:33
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. plenderj The documentation for the FileSystemWatcher class specifically states your observed behaviour Common file system operations might raise more than one event.

FileSystemWatcher changed event (for “LastWrite”) is unreliable

|▌冷眼眸甩不掉的悲伤 提交于 2019-11-30 22:26:19
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 polling for that? The code: class Program { static void Main(string[] args) { FileSystemWatcher watcher =

Finding the user who modified the shared drive folder files

I have a shared drive which is elsewhere on a server. I want to get a notification which gives me the user name of the person who has modified any file present in the shared drive. Currently I am using the FileSystemWatcher to get the notification and the code provided by Stack overflow question " Find out username(who) modified file in C# " to find the user name. But Instead I get the name of the computer on which the shared drive is at the moment. I want the username who had modified the file on the shared drive. My piece of code is : private string GetSpecificFileProperties(string file,

Notification callback in iOS when iTunes sync/file transfer is complete

↘锁芯ラ 提交于 2019-11-30 15:05:22
I have searched for how to receive callbacks in iOS5 when the file system has changed. I've found the following sample from Apple's site, but it only notifies the given delegate when a file is removed/created. DirectoryWatcher class in the DocInteraction sample app http://developer.apple.com/library/ios/#samplecode/DocInteraction/Introduction/Intro.html#//apple_ref/doc/uid/DTS40010052 Is there an API call that I can make to receive a "sync is complete" callback event? Note, a user might transfer large files and I need to know when the transfer is complete. Also, in iOS5, iTunes sync can occur

Using a FileSystemWatcher with Windows Service

a 夏天 提交于 2019-11-30 14:49:56
I have a windows service which needs to monitor a directory for files and then move it to another directory. I am using a FileSystemWatcher to implement this. This is my main Service class. public partial class SqlProcessService : ServiceBase { public SqlProcessService() { InitializeComponent(); } protected override void OnStart(string[] args) { FileProcesser fp = new FileProcesser(ConfigurationManager.AppSettings["FromPath"]); fp.Watch(); } protected override void OnStop() { } } This is my FileProcessor Class public class FileProcesser { FileSystemWatcher watcher; string directoryToWatch;

FileSystemWatcher does not report changes in a locked file

I'm monitoring a folder using a FileSystemWatcher like this: watcher = new FileSystemWatcher(folder); watcher.NotifyFilter = NotifyFilters.Size; watcher.Changed += changedCallback; When I open a new file in notepad in that folder and save it, I get a notification. If I keep writing and then I save, I get a notification. If I close the file with saving it, I get a notification. Exactly what I wanted. However, it turns out that if I create a file in that folder and I set its sharing mode to FileShare.Read, and then I write to it, I will not get any notifications until the file is closed. Another

Powershell and System.IO.FileSystemWatcher

I am new to PowerShell and I am trying to use the System.IO.FileSystemWatcher to monitor the presence of a file in a specified folder. However, as soon as the file is detected I want to stop monitoring this folder immediately and stop the FileSystemWatcher. The plan is to incorporate the PowerShell script into a SQL Agent to enable users to restore their own databases. Basically I need to know the command to stop FileSystemWatcher from monitoring as soon as one file is found. Here is the script so far. ### SET FOLDER TO WATCH + FILES TO WATCH + SUBFOLDERS YES/NO $watcher = New-Object System.IO

Monitor multiple folders using FileSystemWatcher

戏子无情 提交于 2019-11-30 08:05:55
Whats the best way to monitor multiple folders (not subdirectories) using FileSystemWatcher in C#? I don't think FSW supports monitoring multiple folders, so just instantiate one per folder you want to monitor. You can point the event handlers at the same methods, though, which should end up working like I think you want. The easiest way is to create multiple instances of the FileSystemWatcher object. http://www.c-sharpcorner.com/UploadFile/mokhtarb2005/FSWatcherMB12052005063103AM/FSWatcherMB.aspx You'll have to make sure the you handle events between the two folders correctly: Although some

BackgroundWorker & Timer, reading only new lines of a log file?

限于喜欢 提交于 2019-11-30 05:10:44
My application writes a log file (currently using log4net ). I'd like to setup a timer and a background worker to read the log file and print its content into some control in my form, while it's being written. I can't use the FileSystemWatcher class because seems broken: sometimes the event "changed" fires, sometimes do not. And it has an extremely low "pooling rate". So I created a Timer and a FileSystemWatcher. On the "tick" event of the timer, the background worker does its job. The question is: how to read only the lines that are added since the last check of the worker? public LogForm() {

FileSystemWatcher and windows 7

I am writing a tool that monitors a network directory and is running off of a Windows Server 2008 machine, the OnChanged event for the FileSystemWatcher is being fired correctly from files placed on the network drive by any computer that is not using Windows 7, for some reason if the amount of files copied is more than 19 on a windows 7 computer (at once) then no events are fired although it works if files are done individually. Is there a workaround for this or is that just how the Windows 7 kernel behaves with FSW events? Just to clarify it works for thousands of files when copied from an XP
