Global Unlock

Demonstrates how to unlock the Chilkat API with a global (Bundle) purchased unlock code, or with a 30-day trial unlock code. Pascal (Lazarus/Delphi)

  //  The Chilkat API can be unlocked for a fully-functional 30-day trial by passing any

  //  all subsequently instantiated objects are created in the unlocked state. 
  //  
  //  <b>After licensing Chilkat, replace the "Anything for 30-day trial" with the purchased unlock code.</b>
  //  To verify the purchased unlock code was recognized, examine the contents of the LastErrorText
  //  property after unlocking.  For example:
  glob := TGlobal.Create;
  success := glob.UnlockBundle('Anything for 30-day trial');
