Description

No actions are performed in the method at design-time, or when values have not been assigned to the HelpInfo member in Message.

When HelpInfo has a HELPINFO_WINDOW context type, FindControl is called to locate and display the help for the control with the item handle in Message. When HELPINFO_MENUITEM is the context type, GetHelpContext in Menu is called to locate the control ID in Message. If not found, the item handle in Message is used. As a default, the value in the Context property is used to display the context help.
