Begginer - WinForm programming

Hi Wisdom Mandizvidza! There are at least one thousand ways to do that :) For example you can (In the 'click' event method from Form1):

Form2 secondForm = new Form2();
secondForm.Show();
secondForm.Hide();

But this makes little sense. Depending on what you're going to use the second form for I'd advise you to just create the second form and not show it until it's needed (just skip methods 'Show' and 'Hide').

Tell me if this was helpful please.
Cheers!

EDIT:
I've read your question again and I think you could ask about something different: how to show a form and then hide the button. There's as solution for that too :) Just paste this code in the same method as previous:

Form2 secondForm = new Form2();
secondForm.Show();
(sender as Button).Visible = false;

I hope this helps :)
