Ive looked around abit and tried some things but I cant get the child form to fill parent. Its maximised but the form doesnt fill the area and part of the form is off the bottom of the parent form. Heres some code:-

Private Sub ShowNewForm(ByVal sender As Object, ByVal e As EventArgs) Handles NewToolStripMenuItem.Click, NewToolStripButton.Click, NewWindowToolStripMenuItem.Click

Dim NewMDIChild As New Form1 ' where
' frmcustomerdetails is the child form to be invoked
NewMDIChild.MdiParent = Me
Form1.WindowState = FormWindowState.Maximized
NewMDIChild.Show()


End Sub

Form1 is set to maximise. Thats all any help?
