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.

Return the contents of this hash as a string.

h = { "c" => 300, "a" => 100, "d" => 400, "c" => 300  }
h.to_s   #=> "{\"c\"=>300, \"a\"=>100, \"d\"=>400}"

Element Assignment

Associates the value given by value with the key given by key.

h = { "a" => 100, "b" => 200 }
h["a"] = 9
h["c"] = 4
h   #=> {"a"=>9, "b"=>200, "c"=>4}
h.store("d", 42) #=> 42
h   #=> {"a"=>9, "b"=>200, "c"=>4, "d"=>42}

key should not have its value changed while it is in use as a key (an unfrozen String passed as a key will be duplicated and frozen).

a = "a"
b = "b".freeze
h = { a => 100, b => 200 }
h.key(100).equal? a #=> false
h.key(200).equal? b #=> true

Returns the number of key-value pairs in the hash.

h = { "d" => 100, "a" => 200, "v" => 300, "e" => 400 }
h.length        #=> 4
h.delete("a")   #=> 200
h.length        #=> 3

Returns a new hash created by using hsh’s values as keys, and the keys as values. If a key with the same value already exists in the hsh, then the last one defined will be used, the earlier value(s) will be discarded.

h = { "n" => 100, "m" => 100, "y" => 300, "d" => 200, "a" => 0 }
h.invert   #=> {0=>"a", 100=>"m", 200=>"d", 300=>"y"}

If there is no key with the same value, Hash#invert is involutive.

h = { a: 1, b: 3, c: 4 }
h.invert.invert == h #=> true

The condition, no key with the same value, can be tested by comparing the size of inverted hash.

# no key with the same value
h = { a: 1, b: 3, c: 4 }
h.size == h.invert.size #=> true

# two (or more) keys has the same value
h = { a: 1, b: 3, c: 1 }
h.size == h.invert.size #=> false

Returns true if the given key is present in hsh.

h = { "a" => 100, "b" => 200 }
h.has_key?("a")   #=> true
h.has_key?("z")   #=> false

Note that include? and member? do not test member equality using == as do other Enumerables.

Sets the environment variable name to value. If the value given is nil the environment variable is deleted. name must be a string.

Returns a new hash created by using environment variable names as values and values as names.

Returns the contents of the environment as a String.

Deprecated method that is equivalent to ENV.key

Returns the number of environment variables.

Returns true if there is an environment variable with the given name.

This is a deprecated alias for each_line.

This is a deprecated alias for each_codepoint.

Reads ARGF‘s current file in its entirety, returning an Array of its lines, one line per element. Lines are assumed to be separated by sep.

lines = ARGF.readlines
lines[0]                #=> "This is line one\n"

Returns the next line from the current file in ARGF.

By default lines are assumed to be separated by $/; to use a different character as a separator, supply it as a String for the sep argument.

The optional limit argument specifies how many characters of each line to return. By default all characters are returned.

An EOFError is raised at the end of the file.

Positions the current file to the beginning of input, resetting ARGF.lineno to zero.

ARGF.readline   #=> "This is line one\n"
ARGF.rewind     #=> 0
ARGF.lineno     #=> 0
ARGF.readline   #=> "This is line one\n"

Puts ARGF into binary mode. Once a stream is in binary mode, it cannot be reset to non-binary mode. This option has the following effects:

• Newline conversion is disabled.

• Encoding conversion is disabled.

• Content is treated as ASCII-8BIT.

Returns true if ARGF is being read in binary mode; false otherwise. To enable binary mode use ARGF.binmode.

For example:

ARGF.binmode?  #=> false
ARGF.binmode
ARGF.binmode?  #=> true
