Routine Description:
Function called to display more information on the configuration

setting (if appropriate). If the User "OK's" out of the UI,
then the action code field in the DLL data block is set to the
appropriate (and configuration item-specific) action code so the
"Set" function can be called to perform the desired action. If
the user Cancels out of the UI, then the Action code field is
set to 0 (no action) and no action is performed.

Pointer to the Dll data block passed as an LPARAM.
ReturnValue:
ERROR_SUCCESS if the function succeeds otherwise a
WIN32 error is returned if an error occurs
