WIN32OLE_VARIABLE#inspect → String

Returns the OLE variable name and the value with class name.

static VALUE
folevariable_inspect(VALUE self)
{
    VALUE v = rb_inspect(folevariable_value(self));
    VALUE n = folevariable_name(self);
    VALUE detail = rb_sprintf("%"PRIsVALUE"=%"PRIsVALUE, n, v);
    return make_inspect("WIN32OLE_VARIABLE", detail);
}
WIN32OLE_VARIABLE#name

Returns the name of variable.

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

The result of above script is following:
  xlChart
  xlDialogSheet
  xlExcel4IntlMacroSheet
  xlExcel4MacroSheet
  xlWorksheet
Also aliased as: to_s
static VALUE
folevariable_name(VALUE self)
{
    return rb_ivar_get(self, rb_intern("name"));
}
WIN32OLE_VARIABLE#ole_type

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
