Wat is AVSecure?
----------------
A Delphi Component for application protect and making trial
application versions.
With AV Secure you can register applications avoiding
unauthorized use.
With AV Secure you can create applications trials time limited
puting a period of days between two dates of authorized use.
With AV Secure come a wizard RegWizard.exe. With the wizard you
can register applications either runing it in the target computers
(where the application run) or register it from your own computer
generating the registration code to send later to your users via
email, phone, and so on.
You can register applications in temporal way (255 days max.)
or permanently.
You can enable/disable up to 8 modules in the aplication.
How AVSecure work
-----------------
When your application run in the user PCs, AVSecure calculate a four
digits hexadecimal number called INSTAL CODE, distinct one for each
PC and calculated in basis of serial number from the hardware Hard
Disk. This code must be send to you from the users so you can
generate with the wizard RegWizard.exe the apropiate REGISTRATION
CODE for each user.
Together with the component come a demo application so you can learn
how to use it.
Next enumerate the properties and methods needed to implement
registration of applications with AVSecure.
Properties
----------
AppCode: Decimal number from 1 to 12 digits assigned for you an must
be unique for each application. From this number and the
install code the component calculate the entry in the Windows
registry where to be stored the registration data. This
insure to coexist many applications on same one computer.
NOTE: Important! This property must be assigned before any
other action from the component.
BeginDate: Initial date in the range of authorized use.
Days: Number of days of authorized use starting with BeginDate.
EndDate: Final Date in the range of authorized use.
Expired: Boolean value. When it's TRUE means that application use
is not authorized, for example, when the system date is out
of authorized range.
Registered: Boolean value. It's TURE when the application is
registered in permanently way.
Modules: Array of boolean values (m1, m2, ..) establish the modules
that are enabled. This is optional, only applicable when you
want enable/disable features in the application from the
registration code.
Error: Numeric value. This value indicate the component status and
his values means:
-1 the application is first time running.
0 not errors, normal operation
1 registration code length mismatch
2 instal code bad
3 registration code bad
Methods
-------
procedure Read;
Read from the Windows registry the registration data and put
it in the AVSecure object properties.
procedure Write(RCode:string);
Store in the Windows registry the registration data from the
registration code pased in the string parameter with the
format XXXX-XXXX-XXXX-XXXX.
function Make:string;
This function calculate and return a registration code based
in the content of properties in the AVSecure object.
function check(RCode:string):boolean;
This function evaluate the registration code pased in his
parameter, returning TRUE if it's correct. In addition this
put the corresponding values in the Error property.
procedure clear;
Clear the content of the AVSecure object properties.
procedure Erasereg;
Delete the Windows registry entry with the registration
data for the application.
