i am using FileSystem.DeleteFile, FileSystem.createFile, and FileSystem.CopyFile. Can someone tell me how to know when the process is complete? I am delete file faster than my code can keep up. So i want to know how can i tell if the process of deleting a file for example is done.

---------------
the below if statement will return true (sometime when the file does not exist). As a result of it returning true while the file does not exist i get an error. Is there a better way to determine when i delete the file ?

VB
If System.IO.File.Exists(FILE_NameCopy) = True Then
         My.Computer.FileSystem.DeleteFile(FILE_NameCopy)
         
     End If

The event-oriented approach does not look like some code is "telling" you what happened. The technology is much better: you use event handlers to handle events. Please see:
http://msdn.microsoft.com/en-us/library/ms973905.aspx[^].

Now, how to handle the events you are interested in? This is done using the class System.IO.FileSystemWatcher:

However, be aware of some problems. Please see these CodeProject articles:

Thank you so much. you totally answer my question!!!


but the problem i was having had to do with dropbox. when i delete or create a file dropbox would sync it. while dropbox was syncing it had permession/control over text file result in an error. Once i moved it out of my dropbox it worked fine ...

You are welcome.
I don't really understand what is your drop box and what's the problem. Perhaps you need to ask a separate question.
