[wix-users] Installer dialog guidance

[Joseph L. Casale]

> You could set properties from the dialog and use Registry Components to write the values, but if you want the subkeys written immediately, a deferred custom action with rollback support is your option.

Hey John,
What might be an approach to build up a collection of strings based on user input here?
A CA scheduled from the button push of a dialog control cant set properties. I don't know
how many sets of host/port I will get from the user in this case, so I was hoping to accumulate
them and then write them out myself however accumulating them seems to the trick, not writing them.

Any ideas?

Thanks!
