You see, the watcher was looking at a network drive, and intermittently (as networks will) it was dropping out and then coming back again.
After a little searching, I managed to narrow it down to network outages. Use this setter to enable the trigger: watcher. An application I was working on that used the FileSystemWatcher class and was intended to run 24/7 would periodically stop working. mscorlib : The path is not of a legal form. It works fine on the local folder but when I try to use it over a mapped network I am getting following error: System : The directory name Z:\Pratik Talati\Downloads\shared\input is invalid. watcher.NotifyFilter = NotifyFilters.Attributes | I have created a application that runs on FileWatcher system. if you click it again, it will stop monitoring the file system. Is there any way to filter so it only fires on content changes The file in question is text based but not. The problem is the program using the file makes ownership changes to the file when it is running, resulting in hundreds of alerts. For that, you need an app called File Watcher Utilities. I need to monitor one file for content changes. If you leave the Working Directory field empty, GoLand uses the directory of the file where the File Watcher is invoked. The FileSystemWatcher project, shows how to set up a FileSystemWatcher component and how. Manage files and folders, work with archives in the formats.
For example, I expected that if I included FileName that I would be notified of any changes to an existing file's name.instead Attributes seem to handle that case. To specify a custom working directory, type the path to it in the field, or click and select the directory in the Select Path dialog, or click and select the desired macro from the list in the Macros dialog. NOTE that it isn't entirely intuitive/obvious as to which filters will notify you for specific cases. This way I am notified in all cases where the FileSystemWatcher is able to notify me. My solution was to add every NotifyFilter to my FileSystemWatcher. For example, moving a file (clicking and dragging) from the desktop to the watched location did not raise an event but copying an existing file and pasting a new copy of it (there by creating a new file to the file system and not simply moving an existing one) caused the Changed event to be raised. My problem was that I expected certain actions to cause the FileSystemWatcher Changed event to fire. Try creating the FSW at a point where it will be persisted (eg a program level variable) and see if that sorts you out. In VB.NET, a handler is added to an invocation list of some event instance using AddHandler, removed using RemoveHandler (same as C '+' and. As you add some named methods to the invocation lists of event instances of FileSystemWatcher, you can also remove them. This will of course go out of scope at the end of the method and may well be getting tidied up at that point, thus removing the watches. You can use one of at least two approaches, of different degree of 'lightness'. Copy below URL and spread it at the given pages as reference. You seem to be creating the FileSystemWatcher as a local variable in the setup method. Stop pulling out your hair If isn't working, try communicating over the issues with them, directly.
