VI et elp (state)  ->  error

error    integer    returns the error which occured. A value of zero 
                                 indicates no error occured. See below for a list of 
                                 possible errors.

state     integer    defines the state Balloon Help has to be set to. Use any 
                                 of these values:
                                     0  Disable Balloon Help
                                     1  Enable Balloon Help
                                     2  Toggle Balloon Help

Enables or disables the current Balloon Help state for all applications.

Changing the Balloon Help state has only effect until:
     - the user changes it by chosing the Hide Balloons/Show Balloons 
            menu item in the Help menu.
     - other software changes it again;
     - a restart or shutdown takes place.

When you toggle the Balloon Help state, it is enabled when it was disabled and vice versa.

Example:
  C_INTEGER ($state;$error)

  $state := VI Get Help

  If ($state = 0)

   CONFIRM ("Shall I turn on Balloon Help?")

   If (ok = 1)
    $error := VI Set Help (1)

    If ($error < 0)
     ALERT ("Oops, an error occured while turning Balloon Help on!")
    End If
   End If
  End If
