Accessing a field of a form shouldn't be a problem. Just make sure that at the time you are reading the field it is already assigned.

Public Class Form1
    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        Dim form = New Form2
        Debug.Assert(form.A Is Nothing)

        form.ShowDialog()

        Debug.WriteLine(form.A(0))
    End Sub
End Class



Public Class Form2
    Public A As String()

    Private Sub Form2_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        A = {"abc", "aaa"}
    End Sub
End Class
