filesystemwatcher

According to the API docs for Node 0.4.3 , the fs.watchFile(filename, [options], listener) function starts a routine that will Watch for changes on filename . The callback listener will be called each time the file is accessed. It also says The options if provided should be an object containing two members a boolean, persistent , and interval , a polling value in milliseconds Which indicates that it will check every so often based on what is in interval. But it also says The default is { persistent: true, interval: 0 } . So does that mean it will check every millisecond to see if the file time

I am creating a quick temporary fix so sorry if this is dirty, but- Objective I would like to use Powershells Register-Event cmd to wait for a file dropped in a folder, then call a function that parses the file and outputs it to excel. I don't need help with the coding aspect, just the concept. It is still a little mysterious to me as of where this Event is running and what resources it has to work with. Things I've Tried One .ps1 file with registered events at the bottom, calling a function at the top, called by a batch file. Behavior: Stops on this line: $sr = new-object System.IO

I am trying to use the FileSystemWatcher - and am having some luck.. The goal is to MOVE the file that gets created, from the monitored folder, to a new folder. But... have hit 2 snags. Firstly, if I move 3 files into a folder at once (Select 3 files, ctrl+x, and then ctrl+c into my Monitor Folder), the monitor only triggers for the first file. The other 2 don't get processed.

I've used FileSystemWatcher in the past. However, I am hoping someone can explain how it actually is working behind the scenes. I plan to utilize it in an application I am making and it would monitor about 5 drives and maybe 300,000 files. Does the FileSystemWatcher actually do "Checking" on the drive - as in, will it be causing wear/tear on the drive? Also does it impact hard drive ability to "sleep" This is where I do not understand how it works - if it is like scanning the drives on a timer etc... or if its waiting for some type of notification from the OS before it does anything. I just do

I want to change a GUI property in the OnChanged method... (in actuality im trying to set an image source.. but used a button here for simplicity). This is called everytime filesystemwatcher detects a change in a file.. and it gets to the "top" output.. but catches an exception when it tries to set the button width. but if i put the same code in a button.. it works just fine. I sincerely don't understand why.. can someone help me? private void OnChanged(object source, FileSystemEventArgs e) { //prevents a double firing, known bug for filesystemwatcher try { _jsonWatcher.EnableRaisingEvents =
