脚本程序问题

L-S-Y

我是刚开始学MI，用的是最新1.1.3版本。按照帮助文档中方法运行demo_map.py时出现下面这样的错误，请问这是怎么回事？

Traceback (most recent call last):
  File "<string>", line 37, in <module>
AttributeError: 'MIApp' object has no attribute 'SetTitle'

如果把那个语句注释掉，再运行还会出现下面的错误：
Traceback (most recent call last):
  File "<string>", line 45, in <module>
SystemError: 在单个线程上开始另一个消息循环是无效操作。请改用 Form.ShowDialog。

程序代码：和帮助文档里的完全一样

import clr

clr.AddReferenceByPartialName("System.Windows.Forms")

clr.AddReferenceByPartialName("System.Drawing")

from System.Windows.Forms import *

from System.Drawing import *

clr.AddReference("MeteoInfoC.dll")

from MeteoInfoC import *

myApp = MIApp()

myApp.OpenLayer(".\\Map\\country1.shp")

myApp.SetLegendBreak("country1.shp",0,Color.Yellow,Color.Blue,1,True,False,True)

myApp.OpenGrADSData(".\\Sample\\model.ctl")

myApp.SetDrawType("shaded")

t = 2

myApp.TimeIndex = t

myApp.Display("PS")

myApp.MoveLayerToTop("country1.shp")

myApp.SetTitle("MeteoInfo script demo")

myApp.ProjectLayers("+proj=moll+lon_0=105")

myApp.MapLayout.Refresh()

#myApp.SaveFigure(".\\try.png")

Application.Run(myApp)

37行指的是：myApp.SetTitle("MeteoInfo script demo")
45行指的是：Application.Run(myApp)

另外，我的系统是WIN7 32位的，MI是1.1.3的C#版。麻烦指导一下问题在哪？

那个脚本程序已经过时了，文档没有及时更新。
可以用下面这个脚本程序：
