[Visualpython-users] strange error messages with F1

[Joe H. <hea...@vn...>]

Hi.

I'm running Python 2.1.1 and Visual 2001-12-04 under WinME on a Sony VAIO PCG-F630 notebook. When I press F1 from IDLE (VPython version) or select "Python Documentation" from the menu, I get the following in a debug window:

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\PYTHON21\lib\lib-tk\Tkinter.py", line 1285, in __call__
    return apply(self.func, args)
  File "C:\Python21\Tools\idle_VPython\EditorWindow.py", line 327, in python_docs
    webbrowser.open(self.help_url)
  File "C:\PYTHON21\lib\webbrowser.py", line 43, in open
    get().open(url, new, autoraise)
  File "C:\PYTHON21\lib\webbrowser.py", line 221, in open
    os.startfile(url)
WindowsError: [Errno 2] The system cannot find the file specified: 'C:\\Python21\\Doc\\index.html'


The help file is present and does indeed come up in Netscape, but I've never gotten these error messages before. Invoking F1 subsequent times does not generate any error messages. Any ideas?

 

Cheers,
Joe

I'm not sure I understand your final comment. Are you saying that later 
uses of F1 do get you the help, or rather that later uses of F1 don't do 
anything at all (including not giving you the error message)?

One oddity is the presence of the double backslashes in the URL. But maybe 
that's just an artifact of the error reporting, and the need in a character 
string to represent a backslash by two of them (since for example '\n' is 
end of line).
