????There are two ways to mark a control as safe for scripting and initialization:
????Implement the IObjectSafety interface.
????Provide the following registry keys for the control's CLSID under the Implemented Categories section:
????The following key marks the control safe for scripting:
????{7DD95801-9882-11CF-9FA9-00AA006C42C4}
????The following key marks the control safe for initialization from persistent data:
????{7DD95802-9882-11CF-9FA9-00AA006C42C4}
????Microsoft recommends that you implement IObjectSafety to mark a control as safe or unsafe. This prevents other users from repackaging your control and marking it as safe when it is not.
