The two installations are independent - they each have their own set of installed modules. If the module includes binary files, make sure you get a version of the module compiled for Python 2.4. If the module contains only Python files then the same release will work for both Python versions. Kent ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] Nearly there
I'm also curious, although not surprised - since this is why I tend not
to try to print using the API!, but another possibility is that Win98
doesn't recognise the dot shortcut for a path.
You may need to fill in the explicit path info:

Re: [Tutor] Nearly there
Terry,
Your suggestion works. It also works consistently if you fully define the
path of 'filename'.
eg
filename = "c:/test/testprint.txt"
You are right, shell execute seems to need the full path name with windows
98SE. It is strange that it does not need the full path for win xp + win
2k.
Onto my next problem.
My text file is printing out in portrait. Is there any instruction that I
can use so that notepad prints it in landscape?
Thanks,
John.

I'm wondering if ShellExecute needs a full path to find it under W98.
Try this; add to the top of your code:
import os.path
and change your ShellExecute to this:
win32api.ShellExecute (
0,
"print",
os.path.abspath(filename),
None,
".",
0
)
I have no idea if this will work; and the error message you're getting,
> The code above gives me the error: (31, 'ShellExecute', 'A device attached
> to the system is not functioning.')
doesn't seem to indicate it, but it's one less thing.
I'd love to know the answer when you get it.
