I use a memo to show what is going on a server app. It's a standard TMemo
which only holds so much data - when it gets full, it deletes lines from
the top before appending to the bottom. Is that an option?
Also, I once created a grid that worked off an internal array. The
TStringGrid never had more records in it than what was displayed on the
screen at that time (about 20). I didn't use the scroll bar on the grid,
but had a separate one that looked like it was attached. It was _very_ fast.
That being said, I have to agree with John - there's almost never a good
reason to have that many records instantly accessible. And that applies to
the time I did it as well - there were better ways.
