Sets the curve parameters. generator must be an instance of EC::Point that is on the curve. order and cofactor are integers.

See the OpenSSL documentation for EC_GROUP_set_generator()

Called roughly every {#progress_rate}, this method should convey progress to the user.

@return [void]

How often progress should be conveyed to the user via {#indicate_progress}, in seconds. A third of a second, by default.

@return [Float]

Enables use of shared session key material in accordance with RFC 5705.

Returns true if key is the corresponding private key to the Subject Public Key Information, false otherwise.

Serializes the private key to DER-encoded PKCS #8 format. If called without arguments, unencrypted PKCS #8 PrivateKeyInfo format is used. If called with a cipher name and a password, PKCS #8 EncryptedPrivateKeyInfo format with PBES2 encryption scheme is used.

Serializes the private key to PEM-encoded PKCS #8 format. See private_to_der for more details.

Configures store to look up CA certificates from the system default certificate store as needed basis. The location of the store can usually be determined by:

• OpenSSL::X509::DEFAULT_CERT_FILE

• OpenSSL::X509::DEFAULT_CERT_DIR

See also the man page X509_STORE_set_default_paths(3).

Looks up the latest specification for dependency and adds it to the always_install list.

Defines the callback of event. If you want modify argument in callback, you could use this method instead of WIN32OLE_EVENT#on_event.

ie = WIN32OLE.new('InternetExplorer.Application')
ev = WIN32OLE_EVENT.new(ie)
ev.on_event_with_outargs('BeforeNavigate2') {|*args|
  args.last[6] = true
}

Returns value specified by the member name of VT_RECORD OLE object. If the member name is not correct, KeyError exception is raised. If you can’t access member variable of VT_RECORD OLE object directly, use this method.

If COM server in VB.NET ComServer project is the following:

Imports System.Runtime.InteropServices
Public Class ComClass
    Public Structure ComObject
        Public object_id As Ineger
    End Structure
End Class

and Ruby Object class has title attribute:

then accessing object_id of ComObject from Ruby is as the following:

srver = WIN32OLE.new('ComServer.ComClass')
obj = WIN32OLE_RECORD.new('ComObject', server)
# obj.object_id returns Ruby Object#object_id
obj.ole_instance_variable_get(:object_id) # => nil

Sets value specified by the member name of VT_RECORD OLE object. If the member name is not correct, KeyError exception is raised. If you can’t set value of member of VT_RECORD OLE object directly, use this method.

If COM server in VB.NET ComServer project is the following:

Imports System.Runtime.InteropServices
Public Class ComClass
    <MarshalAs(UnmanagedType.BStr)> _
    Public title As String
    Public cost As Integer
End Class

then setting value of the ‘title’ member is as following:

srver = WIN32OLE.new('ComServer.ComClass')
obj = WIN32OLE_RECORD.new('Book', server)
obj.ole_instance_variable_set(:title, "The Ruby Book")
