Is there a way to launch a new form and have the new form return a
variable back to the parent form? Can this be done without the use of
global variables?

Thanks,
Billy

Sure. Just add a property on the child form. Then the parent can read
that property...

Public Class ChildForm
Inherits System.Windows.Forms.Form

Private value As Integer

..............................
Do stuff that sets the value
..............................

Public ReadOnly Property Value() As Integer
Get
Return Me.value
End Get
End Property

End Class


In your main form

Public Class MainForm

Private Sub ShowTheChild()
Dim child As New ChildForm()
child.ShowDialog(Me)

Dim result As Integer = child.Value
' do stuff with value
End Sub

End Form

Hi Billy, Tom,

Or do the reverse and have a method in the first Form that the second can
call.

That works as well :) Though I usually end up using a property and have
in fact used events to notify the parent form as well.
