You can download the project files here:
Once you open up the project in VWD 2010, open the default.aspx file.
Run the program.
Visually, there is not much to this. The bulk of the work is in getting a web service set up. I just created the default.aspx to show the web service working.
The web service is actually in uniqueid.asmx
Default.aspx consume the web service and displays the results. As you can see, it displays a unique identifier. If you reload the page, there will be a new unique identifier.
The web service take your IP address and the current date/time. I concatenates this information and then performs and MD5 hash on it. This results in a unique identifier based on the IP address, date, and time.
Let me know if you have any questions. I'm here to help.
