Exception has been thrown by the target of an invocation....what is this?

[darrel]

I've written a function that will upload a file. This sort of works. It
works sometimes, and then other times...namely when it tries to write to an
existing directory (but not always), I get this error:

Exception has been thrown by the target of an invocation.

Googling seems to indicate that that's a pretty generic error. Is there any
way to find out more specifics as to what is causing this?

The specific line it appears to choke on is this:

postedFile.SaveAs(savePath & strUploadFileName)

Again, it works sometimes, not others. Both times, it has the same string.
I'm stumped.

Is it when the file already exists? Perhaps it won't automatically
overwrite the file on the filesystem.....or make sure you the aspnet
account has Delete/Modify access in Windows to the target folder, as
creating a file is different permission than deleting/modifying. dunno...

It's something like that. If the folder/directory exists it pukes with that
error. I'm guessing it is a permissions issue, but everything seems OK.
