thanks robert for the reply,and i have understood your revision on my script and i also feel sorry for not making you understand my intention,and here i will say it once more.
  it  is a python script project which uses python/c api to make the python interpreter for the script.and the python script part is something a simple frame , and in the c/c++ part, the work will involve with extending the python script functionality.
  which starts like:
  Py_Initialize();
  PyImport_ImportModule("app");
  and later goes on with the other operation
  and the nightmare comes when  i import the app python script.and it throws the notorious import error:ImportError:no module named "_core_",which actually resides in the location of C:\Python24\Lib\site-packages\wx-2.6-msw-unicode\wx,with other files named _core.py, _core.pyc. it seems that the python doesnot find the search path.and i added to the sys.path, to check whether the path now can be found,i type "import _core_".it response by"no module named _core_",.furthermore after checking this failure, i add the _core_.pyd,_core.py,_core.py directory to the path(advance->environment variable).certainly the sys.path increase the specific directory.but still when wanting to check whether it is feasible,the error remains(no module named "_core_").
  hope that u can get what i explains to u, pls be patient with a non-english country guy.thanks again :)
  regards,
  jolley

  Hello Jolley. I'm not sure what is going on with your code, but try
this for the Python side of things:

import wx

class MyApp(wx.Frame):
def __init__(self, title='MyApp'):
self.app = wx.PySimpleApp()
self.title = title
self.windowCaption = title
wx.Frame.__init__(self,None,wx.ID_ANY, self.windowCaption,
size=(200,100),
style=wx.DEFAULT_FRAME_STYLE|
wx.NO_FULL_REPAINT_ON_RESIZE)

app = MyApp()
app.mainloop()

I posted a more elaborate example to the list last week.

Robert
