I released a new version of my software using the TCP server/client method
to communicate with a separate elevated app where I do my HKLM writing etc.
But this is turning out to be a nightmare with firewalls.
The proper method is to write a DLL which does som
There is no problem at all using this function in multiple threads if you
don't need to change the Format Settings. To quote from the D7

The first form of FloatToStrF is not thread-safe, because it uses
localization information contained in global variables.

I often use the Object property of listbox and TStringList items to store
pointers, or just numbers for array subscripts. I don't see any problem doing
that as it can save a lot of time. It is just an integer variable internally.
I seem to remember coming across the same problem once (D7) and

the Controls and Messages units, which bloated the exe again. But went
through and found the required constants. I'll post these here in case it

Using D7, mine grows from 100k to around 500k. The size is important for
loading speed and also the final installer package size. Since my software

Tried that already. Just Using Forms and not even using any function
