That is, if you set up the share manually before the first run of your
application, entering the password, etc. (or having the user do it), if
necessary, then you'd just assume that there is a folder \Network\sharename
on computername, and go from there. If that won't work for you, you'll have
to P/Invoke to the WNET routines (WNetAddConnection, etc.). There may have
been some traffic on doing this before, so check the newsgroup archives.
