[AccessD] Replication as a tool for updating FE

Thanks David.  Might be a good 'get my feet wet' project in .net to see if I
can get your code working.

Jennifer, another thing you can do is launch a batch file or some
other type of file.

I wrote a little VB.Net "launcher" that I use. I compile it one time
and create a text file (renamed to *.ini)
that contains two lines:
LatestVersion:PS_010.adp
DeleteVersion:PS_00*.adp

When I "release" a new versionof the FE, I simply copy the ADP (or
MDB, ACCDB) to the network, rename the file and increment the first
line in the ini file by one.
I like to leave the previous version incase I make a mistake and want
to quickly resort back to the old version. If I decided to delete a
block of old FE's still on the users system,
I put an asterisk in the "Delete" line (the example above will delete
PS_001.adp to PS_009.adp, if they exist on the users PC)

The compiled exe is copied to the users' desktop and they double click
it to launch the file.

The app starts, checks if the latest version already exists on the
users' PC. If it does, it launches it, if not it copies it over and
launches it.

Very simple. (a batch file can do the same, but this was a neat fun
.net project for me to write)
