Use Vizard 2.5 with Python 2.4.1 / IDLE 1.1.1
We are evaluating Vizard 2.5 and want to use it with Python 2.4.1 and the IDE "IDLE 1.1.1 " ( instead of the build-in "2.3.3 (#51, Dec 18 2003, 20:22:39" ) loaded from the Python web site.

Reason : The debugger is well integrated in the IDLE
Problem : An error occurs because of incompatibility of a DLL when tries to import win32process

Error message :

Traceback (most recent call last):
File "D:\Temp\", line 8, in -toplevel-
import viz
File "C:\Program Files\Vizard25\", line 16, in -toplevel-
import win32process
ImportError: Module use of python23.dll conflicts with this version of Python.

(I am estonished not to find a "pythonXX.dll" in the directory tree of Python241)

- Is it possible to solve this conflict , and if yes, how ?

Thanks for your help !

Vizard is compiled with Python 2.3, so it will only work with this version. Is there a version of IDLE that works with Python 2.3 that you can use?

:( Thanks for the info, but it does'nt work :
I have installed Python 2.3 (which comes with its IDLE version 1.0)
and added the pathes into C:\Python23\Lib\site-packages, than run the program, but it fails to run with the message
"** WARNING: Your script failed to run, press any key to exit"

Reason : (found with the debgger) : Program exit in at line 1404 :

#If vizard is embedded then we need to exit right away
#so that multiple windows are not created
if mode & EMBEDDED:

called from the first line of my program which is

Is there a hope to go arround this problem ?

(I would be interrested too to use the Integrated Developpement tool of Wingware "Wing IDE" ( , at least a system where debugging (step-by-step etc) is available, as in IDLE with Python 2.3 or 2.4)

Sorry for the delay, I've been at a conference all week. I was able to run Vizard scripts with IDLE, but I had to make a small change. The next version will include this change. I could also send you a patch if you wanted.

There might be a problem though. You mentioned that you wanted to use IDLE because it had a debugger. This won't work because of the way Vizard works. As you already found out from the previous post, Vizard runs the script once to detect any high-level errors then passes it on to the graphics process which actually runs the script. So the debugger won't be able to detect error that occur outside the global scope of the script (i.e callback and timer code).

There is a way to debug Vizard scripts but it works throught the command line. I will try to find some python modules that allow debugging using a graphical interface.

Anyway, let me know if you would like the patch.

Thanks a lot for the answer. it's not a good info, that the debugger will not work !
NO THANK YOU, don't loose more time; I don't need the patch for now, we will buy Vizard with the maintenance, and I hope this new version will be delivered early enough for our needs.
