Hello all, long time no see. I have a question. I am making a program that uses a FileSystemWatcher. Problem is I need it to watch for than one path or drive. Say someone has two HDD', and they want to watch both of them for activty. How I do that? This is what I got thus far, and it aint working.

(Toggle Plain Text)

Private Sub btnfolder_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnfolder.Click
        watcher.Path = lstdrives.CheckedItems.ToString
    End Sub

What am I doing wrong? Please help.

I think you would have to make more than one watcher. It looks form the doco that a FileSystemWatcher can only watch one path (and subdirectories).

So like this?

Dim newwatch as New FileSystemWatcher
For Each drive in lstdrives.items
newwatch
Next

If so like that. How can I get it to assign each one a path, to make sure that two watchers don't have the same path?

My VB is a bit rusty, but I think you would have to allocate an array (or some other sort of collection) of FileSystemWatcher objects. Then inside a loop, set the watcher[i].path to each item in the list.
