Oct 30th, 2006
Hi, I finding difficult to execute this program. The wx.Notebook i created is coming on the splitted frame(self.p2). How do I that. I am started to learn wxPython, and when I run the code, the code doesnot close gracefully, it throughs me an error.

"pythonw.exe has encountered a problem and needs to close. We are sorry for the inconvenience"

I clicked for more information, then I got the error message which I have attached it in text file. Please help me out with this problem.

here is the code.... seems a bit lengthy, sorry about that.
Please help me to find my mistake, and how do I go forward resolving this problem.

Your problem is similar to one just discussed. You are adding a sizer object to a sizer object. That will lead to runtime errors. Look at Ene Uran's comments here:

May 'the Google' be with you!
