Q: forms

[Geoff Jones]

Hi

I have a form (form A) which displays another form (form B). Is there a way,
from formB to see events/variables in formA whilst formB is displayed?

Pass a reference pointing to form A to your instance of form B. You can do
this in a property or a method parameter, for example.

Hi Herfried

Could you give me some example code to do so via a property?

Thanks in advance

Inside FormB, alter the constructor to take a reference to FormA:

'*** FormB ***
Private _formA As FormA

Public Sub New(parentform As FormA)
_formA = parentform
End Sub


Then inside FormA when you show FormB you would call it like this (for
example from a button click):

Dim frmB As New FormB(Me)

Notice that Me refers to FormA and it is passed into FormB. From
inside form B you can use the private variable to access all the
properties/methods of FormA.

Just to add something to Chris's post, if you also want the events declare
the form with withevents

Private _formA As FormA 'no events

Private withevents _formA as FormA 'withe events
