Add System Path?!?

[andrea_gavana at tin.it]

Hello NG,

    I have a GUI (written in wxPython) that calls some external exe files.
Some of them requires that I add to the PATH variable 1 directory. Basically,
the exe are located in:

/MyApp/Solvers/FirstExe
/MyApp/Solvers/SecondExe

And so on, while the dll needed by these exe are located in:

/MyApp/MyDll

These exe files do not work if I don't set the PATH variable also to that
adress. I know I can do it by hand (and also my users can), but I wonder
if there is a way to do it in Python...

Thank you for all suggestions/pointers.

Andrea.
