How can I load one instance of a form to the tabbed document list? I am current running this code.
Private Sub newMDIRadButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles newMDIRadButton.Click
Form5.MdiParent = Me
but if I close the document from the tab and try to load it again, it doesn't work. Also, if I click the button one more time while the form5 loaded, it disappears.
