Calling form controls from Module

[Brent Burgess]

Hi All,

I have a Sub Routine in a module to iterate controls on a form. I get an error about an instance of the object not created.

I have declared the object and set it to the form (ModelsBox = Me). I have done this between two forms previously. Is there something fundamental that I am missing. Is this where the "Friend Shared" comes into play?

Namespace Models_DialogBox

    Public Class Mod_DlgBox
        <CommandMethod("EM")> _
        Public Sub EM()
            LoadForm()
        End Sub
    End Class

End Namespace


Friend Module Module1
    Friend ModelsBox As Form

    Public Sub LoadForm()
        Dim Models As Form = New FrmModBox
        Models.Show()
    End Sub

    Public Sub UpdateStatus()
        For Each oControl As Control In ModelsBox.Controls("TableLayoutPanel1").Controls ' This is the error
            ' my code
        Next
    End Sub

End Module

Friend Class FrmModBox
    Private Sub FrmModBox_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        ModelsBox = Me
    End Sub

End Class

Thanks in advance,

Brent

Why are you creating controls from a module, and not making them in the designer?

[Brent Burgess]

I already have the controls on the form.

I have 9 listview boxes in a table panel (3 x 3). What I want to do is look in the Table Panel and get a specific listvew. I can get it to work if I have

Public Sub UpdateStatus()
        For Each oControl As Control In ModelsBox.Controls("TableLayoutPanel1").Controls ' This is the error
            ' my code
        Next
    End Sub

in the form. My problem is that when an event is triggered in the ListViews, it runs a separate Subroutine, in which it calls the UpdateStatus.

I don't know if that has made it any clearer.
