Description
Enables or disables the action, depending on the availability of the Application object.
Do not call the UpdateTarget method. This method is called automatically so that actions can update themselves according to current conditions.
In THelpAction, UpdateTarget checks whether the global Application variable is assigned, because this object is required to pass help commands on to WinHelp HyperHelp. If Application is assigned, UpdateTarget sets Enabled to true. If not, UpdateTarget sets Enabled to false.
