Question

My newest task is going to be to implement automatic update of a licence:

The program detects that the licence is expired or about to expire and offers the user to automatically upate this. So far so good. Now what is needed:

• The program sends the user’s credentials to a win 2008 server over the internet.
• The server checks the credentials and if they are OK generates a licence file that is sent back.

How to implement these steps if I cannot use .Net technology?

Answer 1

What not instead of transferring a file, think of it like invoking a web service (or web page) on the server and that returning the content of the license file?

In the VB application you then receive the page response and save that to a local file.

This alternative is used in LicenseSpot for online activation. You can check the API documentation for a general idea.
