Referencing a run-time created form

[Beengie]

I am using this code to create a new form...

Dim frmShow As New Form
        With frmShow
            .WindowState = FormWindowState.Maximized
            .MaximizeBox = False
            .MinimizeBox = False
            .BackColor = System.Drawing.Color.Black
        End With
        frmShow.Show()

In a different subroutine, I wanted to reference the now open "frmShow"

What should I do?
