[wxPython] pipe to wxTextCtrl

Ummm... Sorry to be a dork, but you can't possibly use the statement you
listed below. First, all the variations of win32pipe.popen() take two
parameters (not three): commandstring and mode. Second, for
win32pipe.popen3(), the mode options are "t" or "b", not "r" or "w". :frowning:

Also, the popen2 module simply redirects it's calls to the os.popen
equivalent, so I still have the same problem: "bufsize must be -1". *ugh*

So, it appears that the popen() support under Windows isn't completely
compliant. Oh well... what can you do? Not much, I guess. *grin*

Thanks anyway.

I thought Python 2.0 had popen support for win32, maybe not?

I had to use something like this for Windows:

i,o,e = win32pipe.popen3(szCabArcCmd, "r", 0)

stdout = o.readline()
#stderr = e.readline()

while stdout:
     print print stdout
     stdout = o.readline()

The win32pipe comes with the "win32all" package, available on
ActiveState,
if you don't have it.
