Replace %w+% into the environment value of what is contained between the %‘s This method is used for REG_EXPAND_SZ.

For detail, see expandEnvironmentStrings Win32 API.

Returns the size of arguments of the method.

tobj = WIN32OLE::Type.new('Microsoft Excel 9.0 Object Library', 'Workbook')
method = WIN32OLE::Method.new(tobj, 'SaveAs')
puts method.size_params # => 11

Returns major version.

tobj = WIN32OLE::Type.new('Microsoft Word 10.0 Object Library', 'Documents')
puts tobj.major_version # => 8

Returns minor version.

tobj = WIN32OLE::Type.new('Microsoft Word 10.0 Object Library', 'Documents')
puts tobj.minor_version # => 2

Returns the type library major version.

tlib = WIN32OLE::TypeLib.new('Microsoft Excel 9.0 Object Library')
puts tlib.major_version # -> 1

Returns the type library minor version.

tlib = WIN32OLE::TypeLib.new('Microsoft Excel 9.0 Object Library')
puts tlib.minor_version # -> 3

Returns true; retained for compatibility.

Sets the read timeout, in seconds, for self to integer sec; the initial value is 60.

Argument sec must be a non-negative numeric value:

http = Net::HTTP.new(hostname)
http.read_timeout # => 60
http.get('/todos/1') # => #<Net::HTTPOK 200 OK readbody=true>
http.read_timeout = 0
http.get('/todos/1') # Raises Net::ReadTimeout.
