Explain how to use the HelpProvider component to provide help for UI elements.

You can provide either a HelpString or a help topic for UI elements with the HelpProvider. The HelpProvider provides HelpString, HelpKeyWord, and HelpNavigator properties for each control on the form. If no value for the HelpProvider.HelpNameSpace is set, the HelpString will be provided as help. If the HelpNameSpace is set, the HelpProvider will display the appropriate help topic as configured by the HelpKeyWord and HelpNavigator properties. Help for a particular element is displayed when the element has the focus and the F1 key is pressed.
