Form load data before showdialog

[clonfsp]

I have problems with a form and load event.

My form manage items that can be added, deleted or modified. In load code, I initialize all vars to cero. This is OK to be ready to add items.

My problem is with modify and delete. To carry this, I must load vars from a source. So, in my foreing code I have this:

      Dim frm As newMyForm
        frm = New newMyForm()
        Dim resultado As Boolean = frm.duplicar("0003")
        If (resultado = False) Then
            MsgBox("Could not open 0003")
            frm.Close()
            Return
        End If
        frm.ShowDialog()
        Me.Close()

frm.duplicar load data based on 0003 as index.
My problem is that when showdialog is called, all data which were loaded from duplicar funct is put again to cero. How can I avoid this and load correct data into the form.

Thanks
