(<type 'exceptions.NameError'>, NameError("global name 'MenuPage' is not defined",), <traceback object at 0x028BEC38>)

The MenuPage contains buttons to All functions of the PDF shuffler software. This is one such function which retirieves Information about the PDF files.
Problem is, It executes once, goes back to MenuPage , then again if i click on the same function, it again executes but afterwards gives the above exception, dunno why?

How would we know, it is your code, we know nothing. MenuPage is not defined, like it says.

Edited 4 Years Ago by pyTony

Hey, Im really sorry for my noobness, i thought i had attached the files but i didnt...

Anyways, im attaching a Zip which contains:

MenuPage.py which is the Homepage containing all functions to open respective modules
InfoUI.py which is one of the modules.

Like i said before, on clicking respective module button, i want the corresponding module to Open ie its frame to show.

In the MenuPage i have created functions to open each module, they work, but only once. Ie. from MenuPage , on clicking on Info it opens Info, Info will work, then go back to MenuPage, but next time when i click on InfoUI it gives me " NAME Exception Error"... How do i tackle that? Sorry but im new to wx ..

Edited 4 Years Ago by pyTony: Use code from menu to bring up code window to post code

Study style guide PEP8, at least about the using of empty lines. Your code is very hard to read, even I added the code indention to your post.

Ok Sir, ill go through it, but could you please provide me with a solution to my problem. Please!!!

Your code can not be run without MenuPage module without commenting the import statement (the pyPdf and wx I have installed) and also comment out some lines with non-existing png files.

Then after uncommenting self.Show from InfoUI's __init__ the window comes up, I can browse to a file, but there is nothing action button to do something to file. If choose New from menu, the error message window naturally comes up, because there is not class named MenuPage anywhere (and would not be with from MenuPage import * if MenuPage has not class MenuPage in it).
