Creates a new Socket::Option object which contains an int as data.
The size and endian is dependent on the platform.
p Socket::Option.int(:INET, :SOCKET, :KEEPALIVE, 1) #=> #<Socket::Option: INET SOCKET KEEPALIVE 1>
Returns the data in sockopt as an int.
The size and endian is dependent on the platform.
sockopt = Socket::Option.int(:INET, :SOCKET, :KEEPALIVE, 1) p sockopt.int => 1
Logs a message at the info (syslog info) log level, or logs the message returned from the block.
Write data to a registry value named name. When name is nil, write to the ‘default’ value.
type is type value. (see Registry::Constants module) Class of data must be same as which read method returns.
Write value to a registry value named name.
The value type is REG_SZ(write_s), REG_DWORD(write_i), or REG_BINARY(write_bin).
Write value to a registry value named name.
The value type is REG_SZ(write_s), REG_DWORD(write_i), or REG_BINARY(write_bin).
Returns key information as Array of: :num_keys
The number of subkeys.
:max_key_length
Maximum length of name of subkeys.
:num_values
The number of values.
:max_value_name_length
Maximum length of name of values.
:max_value_length
Maximum length of value of values.
:descriptor_length
Length of security descriptor.
:wtime
Last write time as FILETIME(64-bit integer)

Returns the method name with class name.
Returns true if the parameter is input.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook') method = WIN32OLE_METHOD.new(tobj, 'SaveAs') param1 = method.params[0] puts param1.input? # => true
Returns the parameter name with class name. If the parameter has default value, then returns name=value string with class name.
Returns the OLE struct name and member name and the value of member
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
srver = WIN32OLE.new('ComServer.ComClass') obj = WIN32OLE_RECORD.new('Book', server) obj.inspect # => <WIN32OLE_RECORD(ComClass) {"title" => nil, "cost" => nil}>
Returns number which represents type.
tobj = WIN32OLE_TYPE.new('Microsoft Word 10.0 Object Library', 'Documents') puts tobj.typekind # => 4
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 the type name with class name.
ie = WIN32OLE.new('InternetExplorer.Application')
ie.ole_type.inspect => #<WIN32OLE_TYPE:IWebBrowser2>
Returns the type library name with class name.
tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library') tlib.inspect # => "<#WIN32OLE_TYPELIB:Microsoft Excel 9.0 Object Library>"
Returns the number which represents variable kind.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'XlSheetType')
variables = tobj.variables
variables.each do |variable|
puts "#{variable.name} #{variable.varkind}"
end
The result of above script is following:
xlChart 2
xlDialogSheet 2
xlExcel4IntlMacroSheet 2
xlExcel4MacroSheet 2
xlWorksheet 2
Returns the OLE variable name and the value with class name.
Returns true if the stream is finished.
Finishes the stream and flushes output buffer. If a block is given each chunk is yielded to the block until the input buffer has been flushed to the output buffer.
Decompresses string. Raises a Zlib::NeedDict exception if a preset dictionary is needed for decompression.
This method is almost equivalent to the following code:
def inflate(string) zstream = Zlib::Inflate.new buf = zstream.inflate(string) zstream.finish zstream.close buf end
See also Zlib.deflate
Inputs deflate_string into the inflate stream and returns the output from the stream. Calling this method, both the input and the output buffer of the stream are flushed. If string is nil, this method finishes the stream, just like Zlib::ZStream#finish.
If a block is given consecutive inflated chunks from the deflate_string are yielded to the block and nil is returned.
If a :buffer keyword argument is given and not nil:
The :buffer keyword should be a String, and will used as the output buffer. Using this option can reuse the memory required during inflation.
When not passing a block, the return value will be the same object as the :buffer keyword argument.
When passing a block, the yielded chunks will be the same value as the :buffer keyword argument.
Raises a Zlib::NeedDict exception if a preset dictionary is needed to decompress. Set the dictionary by Zlib::Inflate#set_dictionary and then call this method again with an empty string to flush the stream:
inflater = Zlib::Inflate.new begin out = inflater.inflate compressed rescue Zlib::NeedDict # ensure the dictionary matches the stream's required dictionary raise unless inflater.adler == Zlib.adler32(dictionary) inflater.set_dictionary dictionary inflater.inflate '' end # ... inflater.close
See also Zlib::Inflate.new
Closes the GzipFile object. Unlike Zlib::GzipFile#close, this method never calls the close method of the associated IO object. Returns the associated IO object.
Same as IO.
