Delphi Examples

In the example, the Enigma API function EP_TrialExecutions is used to return the total and remaining number of trial executions. If the count of remaining executions is below half of the total trial executions, a warning message will be displayed.

program test;
{$APPTYPE CONSOLE}
uses
  Windows,
  SysUtils,
  enigma_ide in 'include\enigma_ide.pas';
var
  Total, Left : word;
  sMessage : string;
begin
  // This is test application of trial Enigma API functions
  // If the function succeed then it returns true
  // If the function failed then
  // 1. the trial limit on executions number was not set before protection
  // 2. here is unexpected error
  if EP_TrialExecutions(Total, Left) then
  begin
    if Left = 0 then
    begin
      MessageBox(0, 'Your trial period has over!', 'Test application', 0);
    end else
    begin
      if (Total div Left) >= 2 then sMessage := 'You have left more then half executions of your trial! period';
      sMessage := sMessage + format('You have left %d from %d days of your trial period!', [Left, Total]);
      MessageBox(0, PChar(sMessage), 'Test application', 0);
    end;
  end;
  // You may also use EP_TrialDays and EP_TrialExpirationDate
  // functions to control trial period
end.
