Show/Hide text area?

[bezpal]

In Basic MSI Project:
I have a custom dialog where I ask user for new password. User enters password and clicks next. If I don't like his password I'd like to show a message on the dialog. I created a text area with text and set it Visible=False
How do I set it to True on the click of the "Next" button?

Thanks!
