— Registry.open(key, subkey, desired = KEY_READ, opt = REG_OPTION_RESERVED)

— Registry.open(key, subkey, desired = KEY_READ, opt = REG_OPTION_RESERVED) { |reg| … }

Open the registry key subkey under key. key is Win32::Registry object of parent key. You can use predefined key HKEY_* (see Constants) desired and opt is access mask and key option. For detail, see the MSDN. If block is given, the key is closed automatically.

Returns if key is not closed.

Same as Win32::Registry.open (self, subkey, desired, opt)

Close key.

After close, most method raise an error.

disconnects OLE server. If this method called, then the WIN32OLE_EVENT object does not receive the OLE server event any more. This method is trial implementation.

ie = WIN32OLE.new('InternetExplorer.Application')
ev = WIN32OLE_EVENT.new(ie)
ev.on_event() {...}
   ...
ev.unadvise

sets event handler object. If handler object has onXXX method according to XXX event, then onXXX method is called when XXX event occurs.

If handler object has method_missing and there is no method according to the event, then method_missing called and 1-st argument is event name.

If handler object has onXXX method and there is block defined by WIN32OLE_EVENT#on_event(‘XXX’){}, then block is executed but handler object method is not called when XXX event occurs.

class Handler
  def onStatusTextChange(text)
    puts "StatusTextChanged"
  end
  def onPropertyChange(prop)
    puts "PropertyChanged"
  end
  def method_missing(ev, *arg)
    puts "other event #{ev}"
  end
end

handler = Handler.new
ie = WIN32OLE.new('InternetExplorer.Application')
ev = WIN32OLE_EVENT.new(ie)
ev.on_event("StatusTextChange") {|*args|
  puts "this block executed."
  puts "handler.onStatusTextChange method is not called."
}
ev.handler = handler

returns handler object.

Returns help context.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbooks')
method = WIN32OLE_METHOD.new(tobj, 'Add')
puts method.helpcontext # => 65717

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 helpcontext. If helpcontext is not found, then returns nil.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Worksheet')
puts tobj.helpfile # => 131185

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 library file path.

tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library')
puts tlib.path #-> 'C:\...\EXCEL9.OLB'

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 Ruby object wrapping OLE variant whose variant type is VT_ARRAY. The first argument should be Array object which specifies dimensions and each size of dimensions of OLE array. The second argument specifies variant type of the element of OLE array.

The following create 2 dimensions OLE array. The first dimensions size is 3, and the second is 4.

ole_ary = WIN32OLE_VARIANT.array([3,4], VT_I4)
ruby_ary = ole_ary.value # => [[0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0]]

Returns OLE variant type.

obj = WIN32OLE_VARIANT.new("string")
obj.vartype # => WIN32OLE::VARIANT::VT_BSTR

Returns the adler-32 checksum.

Returns true if the stream is closed.

Closes the stream. All operations on the closed stream will raise an exception.

Resets and initializes the stream. All data in both input and output buffer are discarded.

Returns last modification time recorded in the gzip file header.

Closes the GzipFile object. This method calls close method of the associated IO object. Returns the associated IO object.

Same as IO#closed?

Specify the modification time (mtime) in the gzip header. Using an Integer.

Setting the mtime in the gzip header does not effect the mtime of the file generated. Different utilities that expand the gzipped files may use the mtime header. For example the gunzip utility can use the ‘-N` flag which will set the resultant file’s mtime to the value in the header. By default many tools will set the mtime of the expanded file to the mtime of the gzipped file, not the mtime in the header.

If you do not set an mtime, the default value will be the time when compression started. Setting a value of 0 indicates no time stamp is available.

Opens a file specified by filename for writing gzip compressed data, and returns a GzipWriter object associated with that file. Further details of this method are found in Zlib::GzipWriter.new and Zlib::GzipFile.wrap.

Opens a file specified by filename as a gzipped file, and returns a GzipReader object associated with that file. Further details of this method are in Zlib::GzipReader.new and ZLib::GzipFile.wrap.
