    Cannot call Close() while doing CreateHandle

    I get this exception when I call Me.Close on Load event of a Form. The form
    producing the error is an MDI child of another form. Any ideas how I can get
    over this problem please.

    I have tried doing Me.Close on HandleCreated and Activated events but get
    the same exception.

      Simply don't call the form's 'Show' or 'ShowDialog' method or don't set its
      'Visible' property to 'True' instead of closing it in order to prevent it
      from being shown.

          I am replying to my own question for the benefit of others.

          In case you wanted to close an MDI Child on load, then the answer is... do
          it on VisibleChanged event.
