Hi again,
The question might be a tad confusing, but what I want to ask is, if
it's possible to track if and when a variable in an application has
changed, and then grab the new content of that variable?
So, you want to be notified when a field in an external database
changes. Databases commonly do this with triggers. Generally, I've not
had access to the external databases, and so have had to detect changes
in other ways. Depending on what I have access to I'll do one of
several different things ranging from date and time stamp checking (to
know when it changed), through ODBC connections for database access (so
data is always current), to overnight data export and syncing (because
it's good enough). If you describe your environment and requirements
further specific solutions may be offered.
