  Hello Zac,
  
  i think you mean something like this.
  
  Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
      Dim frmForm4 As Form4
      ' Passing a Form Variable.  
      OpenForm(Of Form4)(frmForm4)
    End Sub

  
    Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As  
    System.EventArgs) Handles Button5.Click
      ' Without passing a Form Variable.
      OpenForm1(Of Form5)()
    End Sub

    Private Sub OpenForm(Of FormTypePar As {Form, New})(ByRef myForm As
                                   FormTypePar)
      myForm = New FormTypePar
      myForm.MdiParent = Me
      myForm.Show()
    End Sub

    Private Sub OpenForm1(Of FormTypePar As {Form, New})()
      Dim myForm As Form = New FormTypePar
      myForm.MdiParent = Me
      myForm.Show()
    End Sub

  BTW I didn't have to pass it the type. This worked, thanks again. If you have anymore cool tricks up your sleave pass em on.

  Private Sub OpenGenericForm(Of FormType As {Form, New})(ByRef myForm As FormType)
       myForm = New FormType
       myForm.MdiParent = Me
       myForm.Show()
  End Sub

  OpenGenericForm(Company)

  BTW,

  I don't want to do some kind of Select Case for the myForm.GetType() or If CType(..,..)... blah..

  That bypasses all the wonderful features that 2005 has given us :)

   

  Thanks again
