Windows Installer XML. How can I make a window in which I specify the name of the database, connection parameters, so that later I can execute the script and create the database?

Question

Programming

In order for the installer to create a database after receiving these entered parameters. I know how easy it is to create a database and execute scripts, but I still don’t know about creating windows and exchanging data between them, I haven’t read it yet).

Actually interested in this question. Time is running out, and there is a lot more to read on Wix. If anyone can help with an example, that would be great.
If there is anyone who is generally well versed, then write, I can send you as a task for payment. I can even throw off a couple of simple .NET projects, on the basis of which I will need to make a full-fledged working example with all my requests.
