I having problem get the of a form

here is the code to create the form and load my custom control (from a
button click)

       Dim MatForm As New Form
       Dim NewMatList As New MatListSelection

       MatForm.Size = New Size(395, 218 + btnExit.Height)
       MatForm.StartPosition = FormStartPosition.CenterParent
       MatForm.ShowInTaskbar = False
       MatForm.FormBorderStyle = FormBorderStyle.None

       NewMatList.Dock = DockStyle.Top

       MatForm.Controls.Add(NewMatList)
       MatForm.TopMost = True
       MatForm.Show()

The control fucntion fine

only when i come to dispose of the control, i want to dispose of the
form too

i have try

console.writeline(me.controls.parent.name.tostring)
console.writeline(me.controls.owner....

I get either the name of my control or blank

and many other ways i can think of

I am more than likely missing something

thank in advance

cheers
