Stgstore.zip is an example of how to use structured storage to store a
combination Treeview/listview structure.

This little application was written as a prototype for a work flow modeling
module within an application I am writing for work. I work for a company that
provides applications to the mortgage and consumer lending industries. One of
our objectives in this application was to provide a form of workflow that would
track the progress of a loan through the lending process. After much analysis,
I and others in my programming team determined that the workflow tools on the
market are fine for tracking and moving documents within an organization, but
not for the kinds of tracking, moving and imposing of business rules we fealt
we needed to provide to our customers. Having made this determination, a
treeview, listview type structure seemed most natural. The next problem was
how best to store the work flow entities, as the number of different
permutations a particular loan can go through are quite large. Each loan will
have it's work flow built as different stages of the lending process is completed.
A database file didn't seem to meet the needs. Thus, the use of structured
storage.

The unit E_StgStr encapsulates the calls to Ole2 and provides a pascal like
untyped file interface to writing data to a file within the storage file.
Eventually, there will be much more written to the file, streamed objects,
etc.

Any comments or suggestions as to how I might better implement this or other
comments will be greatly appreciated.
