Make a button do something differently on second click.

I'm making a program which will make the IP of the user change on a click of a button in a web browser created in Vb. I would like it to be able to change it to a different IP on the second click. I'm using modules and believe they are configured correctly. Click one will load code from module1 and I wish for click two to load code from module2. Is there any way to do this. Any help will be appreciated and I can supply code if needed.

Thanks
