1. Using a LCL component means that you must instantiate a form/datamodule
first.
By that time, a database connection may already have been made (just
to name something), which is exactly what you want to avoid.
The check for single instance should be done before the first form is
created.
2. Then it is only available in visually designed applications.
Services, website servers and custom console apps are non-visual.
I am specificially thinking FastCGI processes.
Actually, you could create the LCL component manually in the LPR and use it
non-visually before any code is run (except initialization sections). The
visual component could be only for the hobbyists.
So for me both CustApp or LCL component are OK. You decide :)
Both are OK. Use of one does not exclude use of the other.
I was going to add it in CustApp anyway as soon as I had looked at your
implementation.
