[DUG] Program design question

[Kyley Harris]

I think the original reason for keeping it small is not a reference to
code, or compile size, but to memory execution size? You want to keep
the memory foot print down while it is essentially idle?

Maybe this is backwards code in todays enlightened world of .net and
stuff... but put your code in a dll for the big footprint stuff that
gets lauched occasionally, and call it with explicit dll load and
unload as necessary.

I hate to break it to ya, but a 1 form application is just as big as a
2 form program, until you create the instances at the same time. The
memory foot print comes from the delphi VCL code. If you want a really
small footprint, dont use tform. design it by hand using windows
calls. Its your call what to sacrafice. I know a fellow who did this
with a timesheet program. The exe was only 100k and it was small in
memory too. Had 7 forms at least....

cheers
