Constructor Details

#initialize(server = nil, host = nil) ⇒ WIN32OLE

Creates a new Win32::OLE server object on host, or the localhost if no host is specified. The server can be either a Program ID or a Class ID.

Examples:

# Program ID (Excel)
ole = Win32::OLE.new('Excel.Application')

# Class ID (Excel)
ole = Win32::OLE.new('{00024500-0000-0000-C000-000000000046}')

.const_load(ole, mod = WIN32OLE) ⇒ Object

Defines a constant of an OLE Automation server as a mod constant.

The +ole+ argument is WIN32OLE object or type library name. The
+mod+ argument is a class or module name, which defaults to WIN32OLE
if omitted.

The first letter of a Ruby constant is always upper case. Therefore,
a constant name of WIN32OLE object is capitalized. For example, the
'xlTop' constant of Excel is changed to 'XlTop' in WIN32OLE.

If the first letter of an OLE constant is not in the A-Z range, then
the constant must be referenced via the CONSTANTS hash variable.

Example:

   module EXCEL_CONST; end

   excel = WIN32OLE.new('Excel.Application')

   WIN32OLE.const_load(excel, EXCEL_CONST)

   puts EXCEL_CONST::XlTop # => -4160
   puts EXCEL_CONST::CONSTANTS['_xlDialogChartSourceData'] # => 541

   WIN32OLE.const_load(excel)
   puts WIN32OLE::XlTop # => -4160

   module MSO; end

   WIN32OLE.const_load('Microsoft Office 9.0 Object Library', MSO)
   puts MSO::MsoLineSingle # => 1
