Trapping events in Visual Source Safe

We are running Microsoft Visual Source Safe
(VSS) as our source code control system.

We are interested to trap certain
events: file check-in, file deletion, etc.
and trigger some processes, for example,
rebuild a library dependent on the file
that has been changed.

Can anobody refer me to any technique/tools
(if any), which allows to implement such
traps and processing.

If possible, Visual Basic would be the
best programming choice to handle this
task.

Thanks in advance,

Jerry.
