Loading form ¿? (RESOLVED)

[Sanko]

Hi i have 2 forms "form1" and "MdiPrincipal"

In form1 i have a button when the user do a click the form1 must close and show the mdi

Code:

Private Sub CmdAceptar_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CmdAceptar.Click
Dim Mdi As New MdiPrincipal  
Mdi.Show()
'Mdi.Dispose()
Me.close()

but when i click the button it opens the mdi and then automatically closes

if i use

Mdi.ShowDialog(Me)

it opens the Mdi but the form1 is already open

if i use

Me.hide()

the form1 is invisible but is in memory...

I want to close the form1 and open the Mdi
