类 WIN32OLE::Variable
WIN32OLE::Variable
对象表示 OLE 变量信息。
公共实例方法
inspect → String 点击切换源码
返回 OLE 变量名称和带类名称的值。
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); }
name 点击切换源码
返回变量的名称。
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
static VALUE folevariable_name(VALUE self) { return rb_ivar_get(self, rb_intern("name")); }
也别名为:to_s
ole_type 点击切换源码
返回 OLE 类型字符串。
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
static VALUE folevariable_ole_type(VALUE self) { struct olevariabledata *pvar; TypedData_Get_Struct(self, struct olevariabledata, &olevariable_datatype, pvar); return ole_variable_ole_type(pvar->pTypeInfo, pvar->index); }
ole_type_detail 点击切换源码
返回类型的详细信息。该信息是类型数组。
tobj = WIN32OLE::Type.new('DirectX 7 for Visual Basic Type Library', 'D3DCLIPSTATUS') variable = tobj.variables.find {|variable| variable.name == 'lFlags'} tdetail = variable.ole_type_detail p tdetail # => ["USERDEFINED", "CONST_D3DCLIPSTATUSFLAGS"]
static VALUE folevariable_ole_type_detail(VALUE self) { struct olevariabledata *pvar; TypedData_Get_Struct(self, struct olevariabledata, &olevariable_datatype, pvar); return ole_variable_ole_type_detail(pvar->pTypeInfo, pvar->index); }
to_s()
返回变量的名称。
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
别名为: name
value 点击切换源码
如果值存在,则返回值。如果值不存在,此方法返回 nil。
tobj = WIN32OLE::Type.new('Microsoft Excel 9.0 Object Library', 'XlSheetType') variables = tobj.variables variables.each do |variable| puts "#{variable.name} #{variable.value}" end The result of above script is following: xlChart = -4109 xlDialogSheet = -4116 xlExcel4IntlMacroSheet = 4 xlExcel4MacroSheet = 3 xlWorksheet = -4167
static VALUE folevariable_value(VALUE self) { struct olevariabledata *pvar; TypedData_Get_Struct(self, struct olevariabledata, &olevariable_datatype, pvar); return ole_variable_value(pvar->pTypeInfo, pvar->index); }
variable_kind 点击切换源码
返回变量种类字符串。
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
static VALUE folevariable_variable_kind(VALUE self) { struct olevariabledata *pvar; TypedData_Get_Struct(self, struct olevariabledata, &olevariable_datatype, pvar); return ole_variable_kind(pvar->pTypeInfo, pvar->index); }
varkind 点击切换源码
返回表示变量种类的数字。
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
static VALUE folevariable_varkind(VALUE self) { struct olevariabledata *pvar; TypedData_Get_Struct(self, struct olevariabledata, &olevariable_datatype, pvar); return ole_variable_varkind(pvar->pTypeInfo, pvar->index); }
visible? 点击切换源码
如果变量是公共的,则返回 true。
tobj = WIN32OLE::Type.new('Microsoft Excel 9.0 Object Library', 'XlSheetType') variables = tobj.variables variables.each do |variable| puts "#{variable.name} #{variable.visible?}" end The result of above script is following: xlChart true xlDialogSheet true xlExcel4IntlMacroSheet true xlExcel4MacroSheet true xlWorksheet true
