the issue is that vb6 had default instances created for declared forms, while vb7 doesn't (it will again in 2005), and the way you're doing it you're creating a new, different form1 - so you won't see any changes you do to it unless you call show() on it, and then you'll get two form1's being shown.

What you need to do is:
- Add a public global variable of the form1 type to your form2
- When you create an instance of the new form2 from form1, assign "Me" to that variable - for example, in form1:
Dim frm2 as new Form2
frm2.m_Form1 = Me
- Now on Form two you can mess with form1 as much as you want through that variable.

Hope that helps

Got it Alexandre, thanks for your help!
I use a module and works fine:

Module Teste
Public frm1 As Form1
End Module

and then in form1.load ...
Teste.frm1 = Me

then in form2 button1.click ...
frm1.StatusBar1.Text = "SIMPLE TESTE"

now it works great! :)

Thank you (muito obrigado)!
