ApplyInvisibleKey

Name

ApplyInvisibleKey

Purpose

Insert an Activation Key to change the properties of a module or to change the Copy Protection. The difference to ApplyActivationKey is that this key is not displayed inside Licence Viewer.

Params

Parameter	Type	Example	Note
Activation Key	String	UIGC345EPR5820AHKLD35PM5F3M323K	A key that is 32 characters long or an empty string to open a input window

Returncode

Returncode Type Integer	Note
0	The Activation Key was successfully added to the licence file
258	The Activation Key could not be read, possibly a wrong key
257	This Activation Key was already used
Other return codes	Operation failed, see list of return codes

Usage

Add a received Activation Key to the licence file or open a dialog to let the user enter a needed key. Note: Only those keys with appropriate installation codes could be applied. The entered key is in Licence Viewer only displayed as a sequence of stars not as the real characters. This may be useful to use general keys that should not be copied to other systems.
