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 := CkGlobal_Create();success := CkGlobal_UnlockBundle(glob,'Anything for 30-day trial');if (success <> True) then begin Memo1.Lines.Add(CkGlobal__lastErrorText(glob)); Exit; end;status := CkGlobal_getUnlockStatus(glob);if (status = 2) then begin Memo1.Lines.Add('Unlocked using purchased unlock code.'); endelse 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.Memo1.Lines.Add(CkGlobal__lastErrorText(glob));CkGlobal_Dispose(glob);end;
