Single user EXE

[DaveJohnson]

Can a compiled Exe be set to only allow a single user and if anther user loads gets an error message.

I have an EXE which add records to a database and dont want it open more than once.

Thanks

You need to do some code around that yourself, or buy one of the commercial tools that allow user count restrictions.


One way is to create a small client/server tcp/ip program that listens to a particular port. Whenever you load the program you browse the network to see if you already have your program loaded on that port in another/same computer, and if so just issue a message and exit.
