I have added a custom dialog in a setup. I chose the Textboxes (A) dialog. I put Visible=False to the last three and only kept the first one. So, I ask the user to enter a key. Now, where do I put the code to negotiate with that? And, how do I access those properties? I see I can put some code in ProjectInstaller.vb. But, it is mostly about the interaction I need to know.
