// The Chilkat API can be unlocked for a fully-functional 30-day trial by passing any
// string to the UnlockBundle method.  A program can unlock once at the start. Once unlocked,
// all subsequently instantiated objects are created in the unlocked state. 
// 
// After licensing Chilkat, replace the "Anything for 30-day trial" with the purchased unlock code.
// To verify the purchased unlock code was recognized, examine the contents of the LastErrorText
// property after unlocking.  For example:
glob := TChilkatGlobal.Create(Self);
success := glob.UnlockBundle('Anything for 30-day trial');
if (success <> 1) then
  begin
    Memo1.Lines.Add(glob.LastErrorText);
    Exit;
  end;

status := glob.UnlockStatus;
if (status = 2) then
  begin
    Memo1.Lines.Add('Unlocked using purchased unlock code.');
  end
else
  begin
    Memo1.Lines.Add('Unlocked in trial mode.');
  end;

// The LastErrorText can be examined in the success case to see if it was unlocked in
// trial more, or with a purchased unlock code.
