Im making an Anti-Leak for my program. Have created the function already that checks the hardware ID and every but i have a problem! How can i add multiple hardware id's in one string. Example:
HardID : String = "MY HARDWARE ID";
Where the "my hardware id" is that's where the client's ID goes. I have an update base so i have to add multiple ID for each clients! Please can anyone tell me how can i add multiple "MY HARDWARE ID" into that one string. Here is the function:

begin
if GetHardwareID = HardID then
Form4.show
else
Application.Terminate;

Why dont you change it to

if (HardwareIdIsValid(HardID)) then
begin

end else
  Application.Terminate;

Then you could have a function with multiple hardware IDS embedded.
