Available: Freeware Program Registration Lock/Unlock Source Code for VB Shareware Programmers
Hi,
If you want some example code on how to implement the
following:
1. Upon user installation, your program gives him a lock code and
allows the user to run the program for a certain number of times.
Once the max count is reached, the program stops functioning.
(The user will need to send you the lock code, if he wants to
register the program.)
2. During this evaluation mode, you can also limit the user to
certain program functions, i.e. not all program features are allowed.
3. Upon user registration and receipt of the cheque, you use a
program to generate a key code, send it to them.
4. The user enters the key code and the program becomes fully
functional, in terms of program features and without any run count
limitation.
E-mail me, if you are interested to have a copy of the source code
(written in VB4 16 & 32 bit versions).
Sincerely,
Sean Yeoh
