Hello Alan,
Thank you for your response.
I want to do it from a GUI (with wxPython).
I work with Windows XP SP3, python 2.5 and wxPython 2.8.9.2.
subprocess.Popen(args = ["notepad", filename]) works fine.
Same for subprocess.Popen(["C:\Program Files\Editra\Editra.exe", filename]).
It opens the file with notepad or Editra without problems.
subprocess.Popen("notepad") or subprocess.Popen("C:\Program
Files\Editra\Editra.exe") work also fine.
Conversely, subprocess.Popen("notepad++") doesn't work.
If I do subprocess.Popen(args = ["notepad++", filename]), I get an exception.
The exception is as follows:
Traceback (most recent call last):
File "<pyshell#22>", line 1, in <module>
s.Popen(args = ["notepad++.exe", "c:\\Redirect.txt"])
File "C:\Python25\lib\subprocess.py", line 594, in __init__
errread, errwrite)
File "C:\Python25\lib\subprocess.py", line 816, in _execute_child
startupinfo)
WindowsError: [Error 2] Le fichier spécifié est introuvable (the specified file
cannot be found)
I tried several other ways without any success:
subprocess.Popen(args = ["notepad++.exe", filename])
subprocess.Popen(args = ["C:\Program Files\Notepad++\notepad++.exe", filename])
I wonder if it is due to the location of the softwares.
Notepad.exe is located in C:\WINDOWS while notepad++ is located in C:\Program
Files\Notepad++

Do you mean that it is not always possible to open another software from python,
notably if the software doesn't have a COM interface ?

os.getenv is always None, which may be correct since I am on Windows ?
Thanks a lot for your help.
