Delete a subkey named name and all its values.

If recursive is false, the subkey must not have subkeys. Otherwise, this method deletes all subkeys and values recursively.

Returns OLE type of WIN32OLE_PARAM object(parameter of OLE method).

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook')
method = WIN32OLE_METHOD.new(tobj, 'SaveAs')
param1 = method.params[0]
puts param1.ole_type # => VARIANT

Returns value specified by the member name of VT_RECORD OLE variable. Or sets value specified by the member name of VT_RECORD OLE variable. If the member name is not correct, KeyError exception is raised.

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

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

Then getting/setting value from Ruby is as the following:

obj = WIN32OLE.new('ComServer.ComClass')
book = WIN32OLE_RECORD.new('Book', obj)
book.title # => nil ( book.method_missing(:title) is invoked. )
book.title = "Ruby" # ( book.method_missing(:title=, "Ruby") is invoked. )

Returns array of WIN32OLE_TYPE objects defined by the typelib type library. This method will be OBSOLETE. Use WIN32OLE_TYPELIB.new(typelib).ole_classes instead.

returns type of OLE class.

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

Returns the WIN32OLE_TYPELIB object which is including the WIN32OLE_TYPE object. If it is not found, then returns nil.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Worksheet')
puts tobj.ole_typelib # => 'Microsoft Excel 9.0 Object Library'

Returns the type library file path.

tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library')
classes = tlib.ole_types.collect{|k| k.name} # -> ['AddIn', 'AddIns' ...]

Returns the type library file path.

tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library')
classes = tlib.ole_types.collect{|k| k.name} # -> ['AddIn', 'AddIns' ...]

Returns OLE type string.

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

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

Returns variable kind string.

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

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

Returns OS code number recorded in the gzip file header.

Returns true if stat is readable by the real user id of this process.

File.stat("testfile").readable_real?   #=> true

If stat is readable by others, returns an integer representing the file permission bits of stat. Returns nil otherwise. The meaning of the bits is platform dependent; on Unix systems, see stat(2).

m = File.stat("/etc/passwd").world_readable?  #=> 420
sprintf("%o", m)                              #=> "644"

Returns true if stat is writable by the real user id of this process.

File.stat("testfile").writable_real?   #=> true

If stat is writable by others, returns an integer representing the file permission bits of stat. Returns nil otherwise. The meaning of the bits is platform dependent; on Unix systems, see stat(2).

m = File.stat("/tmp").world_writable?         #=> 511
sprintf("%o", m)                              #=> "777"

Same as executable?, but tests using the real owner of the process.

Removes fields from self as selected by the block; returns self.

Removes each field for which the block returns a truthy value:

source = "Name,Name,Name\nFoo,Bar,Baz\n"
table = CSV.parse(source, headers: true)
row = table[0]
row.delete_if {|header, value| value.start_with?('B') } # => true
row # => #<CSV::Row "Name":"Foo">
row.delete_if {|header, value| header.start_with?('B') } # => false

If no block is given, returns a new Enumerator:

row.delete_if # => #<Enumerator: #<CSV::Row "Name":"Foo">:delete_if>

Removes rows or columns for which the block returns a truthy value; returns self.

Removes rows when the access mode is :row or :col_or_row; calls the block with each CSV::Row object:

source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
table = CSV.parse(source, headers: true)
table.by_row! # => #<CSV::Table mode:row row_count:4>
table.size # => 3
table.delete_if {|row| row['Name'].start_with?('b') }
table.size # => 1

Removes columns when the access mode is :col; calls the block with each column as a 2-element array containing the header and an Array of column fields:

source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
table = CSV.parse(source, headers: true)
table.by_col! # => #<CSV::Table mode:col row_count:4>
table.headers.size # => 2
table.delete_if {|column_data| column_data[1].include?('2') }
table.headers.size # => 1

Returns a new Enumerator if no block is given:

source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
table = CSV.parse(source, headers: true)
table.delete_if # => #<Enumerator: #<CSV::Table mode:col_or_row row_count:4>:delete_if>
