IMPORTANT NOTE TO rKey USERS :
RkPlus is NOT compatible with rKey! If you have written a program using rKey,
you will have to make several changes to allow it to compile and run under
RkPlus. The following are the major differences between RkPlus and rKey :
(1) RkPlus uses 12 alphanumeric characters to build keys.
rKey used 12 hexadecimal digits.
(2) RkPlus allows up to 3 strings may be used in key encryption.
rKey allowed only 1.
(3) RkPlus now allows an optional expiration date to be embedded in the key.
(4) RkPlus groups all Registration information into the Reg record.
rKey had individual variables.
(5) RkPlus returns result codes in the enum Status (in the Reg record).
rKey returned results in the booleans RegError and RegStatus.
(6) The MakeKey and ValidKey functions require additional parameters in
RkPlus (to allow for the new features).
(7) The Register procedure has been replaced by SaveRegInfo in RkPlus, which
uses information in the Reg record (rather than parameters).
(8) RkPlus features the additional procedures SetRegInfo, CreateKey and
VerifyKey. SetRegInfo allows you to load information into the Reg
record in a single statement. CreateKey and VerifyKey are higher-level
versions of MakeKey and ValidKey. Both uses information in the Reg
record and VerifyKey returns result codes in Status (in the Reg record).
(9) The RkPlus registration key file has the extension of .REG.
The rKey registration key file had the extension of .KEY.
If you don't feel that you need these enhanced features, a new smaller
version of rKey is also available (as RKEY14.ZIP).
If you have already registered any version of rKey ($10 or more), you can
register RkPlus AND rKey for $10. If you have not yet registered rKey, you can
register both for $20.
If you have any trouble converting to RkPlus, feel free to contact me via any
of the methods listed in RKPLUS.DOC.
