Creates a digest object and reads a given file, name. Optional arguments are passed to the constructor of the digest class.

p Digest::SHA256.file("X11R6.8.2-src.tar.bz2").hexdigest
# => "f02e3c85572dc9ad7cb77c2a638e3be24cc1b5bea9fdbb0b0299c9668475c534"

Array of the currently loaded libraries.

Clear the reference to the object this is pinning.

Returns true if the reference has been cleared, otherwise returns false.

Returns true if this is a null pointer.

It is only necessary to run cleanup when engines are loaded via OpenSSL::Engine.load. However, running cleanup before exit is recommended.

Note that this is needed and works only in OpenSSL < 1.1.0.

The file name of the input.

returns the cmsg level as an integer.

p Socket::AncillaryData.new(:INET6, :IPV6, :PKTINFO, "").level
#=> 41

returns the socket level as an integer.

p Socket::Option.new(:INET6, :IPV6, :RECVPKTINFO, [1].pack("i!")).level
#=> 41

sets event handler object. If handler object has onXXX method according to XXX event, then onXXX method is called when XXX event occurs.

If handler object has method_missing and there is no method according to the event, then method_missing called and 1-st argument is event name.

If handler object has onXXX method and there is block defined by WIN32OLE_EVENT#on_event(‘XXX’){}, then block is executed but handler object method is not called when XXX event occurs.

class Handler
  def onStatusTextChange(text)
    puts "StatusTextChanged"
  end
  def onPropertyChange(prop)
    puts "PropertyChanged"
  end
  def method_missing(ev, *arg)
    puts "other event #{ev}"
  end
end

handler = Handler.new
ie = WIN32OLE.new('InternetExplorer.Application')
ev = WIN32OLE_EVENT.new(ie)
ev.on_event("StatusTextChange") {|*args|
  puts "this block executed."
  puts "handler.onStatusTextChange method is not called."
}
ev.handler = handler

returns handler object.

Returns true if the method is public.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbooks')
method = WIN32OLE_METHOD.new(tobj, 'Add')
puts method.visible? # => true

Returns help file. If help file is not found, then the method returns nil.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbooks')
method = WIN32OLE_METHOD.new(tobj, 'Add')
puts method.helpfile # => C:\...\VBAXL9.CHM

Returns default value. If the default value does not exist, this method returns nil.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook')
method = WIN32OLE_METHOD.new(tobj, 'SaveAs')
method.params.each do |param|
  if param.default
    puts "#{param.name} (= #{param.default})"
  else
    puts "#{param}"
  end
end

The above script result is following:
    Filename
    FileFormat
    Password
    WriteResPassword
    ReadOnlyRecommended
    CreateBackup
    AccessMode (= 1)
    ConflictResolution
    AddToMru
    TextCodepage
    TextVisualLayout

Returns true if the OLE class is public.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Application')
puts tobj.visible  # => true

Returns helpfile path. If helpfile is not found, then returns nil.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Worksheet')
puts tobj.helpfile # => C:\...\VBAXL9.CHM

Returns array of WIN32OLE_VARIABLE objects which represent variables defined in OLE class.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'XlSheetType')
vars = tobj.variables
vars.each do |v|
  puts "#{v.name} = #{v.value}"
end

The result of above sample script is follows:
  xlChart = -4109
  xlDialogSheet = -4116
  xlExcel4IntlMacroSheet = 4
  xlExcel4MacroSheet = 3
  xlWorksheet = -4167

Returns true if the type library information is not hidden. If wLibFlags of TLIBATTR is 0 or LIBFLAG_FRESTRICTED or LIBFLAG_FHIDDEN, the method returns false, otherwise, returns true. If the method fails to access the TLIBATTR information, then WIN32OLERuntimeError is raised.

tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library')
tlib.visible? # => true

Returns true if the variable is public.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'XlSheetType')
variables = tobj.variables
variables.each do |variable|
  puts "#{variable.name} #{variable.visible?}"
end

The result of above script is following:
  xlChart true
  xlDialogSheet true
  xlExcel4IntlMacroSheet true
  xlExcel4MacroSheet true
  xlWorksheet true

Returns the adler-32 checksum.
