Patrick,

Here is the code for referencing a form called from outside the form.

-Al

'-------------------------------------------------------------------
'This is a vb class that controls both forms
'(this would be your controller code)

Public Class Class1
Public Shared Sub Main()
Dim frmForm2 As Form2 = New Form2()
Dim frmForm1 As Form1 = New Form1()
frmForm1.Show()

frmForm2 = New Form2()
frmForm2.Process(frmForm1)
Application.Run(frmForm2)
End Sub
End Class

'------------------------------------------------------------------

'Form1 has no added code, but should have a label.
Public Class Form1
Inherits System.Windows.Forms.Form

#Region
'VS created code removed for readability.
#End Region

End Class

'-------------------------------------------------------------------

'Form2 should have a button1 and following code.
Public Class Form2
Inherits System.Windows.Forms.Form
Private mForm As Form

#Region
'VS created code removed for readability.
#End Region

Public Sub Process(ByRef frm As Form)
'Get a reference to the existing form passed in from Class1.
mForm = frm
End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Handles Button1.Click
Dim objControl As Control

'Iterate the controls.
For Each objControl In mForm.Controls
'Find the contol by name.
If objControl.Name = "Label1" Then
objControl.Text = "New Text"
End If
Next

End Sub
End Class
