Send data from vb.Net App to ASP.Net page...

What I want to do is send data from my VB.Net application to a ASP.Net webpage so that this data send can we written to a database which would be handled by the ASP.Net. The reason why I want to do this is because one of my clients has asked for statistics on how many people are using my software, what projects, machine name etc etc. So what I propose to do is when a user logs into my application send this data to an ASP.Net webpage that is located on a central server and this ASP.Net page will then take the data sent an write it to a database.

I have created the ASP.Net webpage called PostUsage.aspx and tested that this can be displayed, which is can. However I have a couple of questions that I need some help with:

1. How can I send data from my VB.Net application to the PostUsage.aspx page?
2. How can I then get/extract the data send to the PostUsage.aspx page, this is now at the PostUsage.aspx page side of things?

Any help, links, examples would really be appreciated.

Thanks in advance
