Help: how to use VB to do the registration process

Boss
I made a piece of software and wanted to make it a registration program. I do n’t know what to do. It seems that there is a registration code based on the hard disk ID number. What should I do?

Another important problem is that I do n’t have a registered program now. I have to test the software for others. I want to add code to the program so that it can be used only a few times, just like the software version. Open it, how to get it

There are functions to access the registry, you can search!

Use the API RegCreateKey to create a key RegSetValue to set the key value
Every time the program starts, the value increases by 1.
Finally, use RegQueryValue to read the key value.
