Because Microsoft Internet Explorer can act as a host for managed controls and components, its security settings affect managed execution. Your managed control might not run in Internet Explorer unless ActiveX controls and scripting are enabled.

To enable Internet Explorer security settings

1. In Internet Explorer, click Internet Options on the Tools menu.
2. Click the Security tab. You can access the settings for the Internet Zone, Local Intranet Zone, Trusted Sites, and Restricted Sites from this tab.
3. Choose the zone in which the managed control originates and click the Custom Level button. Run ActiveX controls and plug-ins and Script ActiveX controls marked safe for scripting must both be enabled for managed ActiveX controls to execute.
