Hi All,
I have my MDI form and 10 child forms, I call the child form on the click
event from the menu using
Dim NewChildFrm As New newCustomerForm

NewChildFrm.MdiParent = Me

NewChildFrm.Show()

What can I prevent to open another newCustomerForm from the menu? if is
already one and open just got focus on the form.

Tks in advance

Herfried,
I got an error...
Local variable 'NewChildFrm' cannot be referred to before it is declared.
But I already declare before...
Tks for you help

I fix this.. the problem now is that the form is created outside the MDI
form and it keeps creating a new one.
Tks
