wxpython - Read a command prompt output in a separate window in python -

i have python script builds solution file using msbuild on windows system.i want show command prompt output when build process running.my code looks below

def build(self,projpath):     if not os.path.isfile(self.msbuild):         raise exception('msbuild.exe not found. path=' + self.msbuild)      arg1 = '/t:rebuild'     arg2 = '/p:configuration=release'     p = subprocess.call([self.msbuild,projpath,arg1,arg2])     print p     if p==1:         return false     return true 

i able build file, need show build status in separate gui(status window).i tried lot redirect command prompt output file , read file but, not make it. tried below command,

subprocess.check_output('subprocess.call([self.msbuild,projpath,arg1,arg2])', shell=false) > 'c:\tmp\file.txt' 

can let me know how can show outputs command prompt in status window(a gui using wxpython) when run script?

i did when wanted capture traceroute , ping commands wxpython. wrote in tutorial: http://www.blog.pythonlibrary.org/2010/06/05/python-running-ping-traceroute-and-more/

first of you'll need redirect stdout, goes this:

redir=redirecttext(log) sys.stdout=redir 

where redirecttext special class accepts wx.textctrl argument. see below:

class redirecttext(object):     def __init__(self,awxtextctrl):         self.out=awxtextctrl      def write(self,string):         self.out.writetext(string) 

and here's example of ping command:

proc = subprocess.popen("ping %s" % ip, shell=true,                          stdout=subprocess.pipe)  print while true:     line = proc.stdout.readline()                             wx.yield()     if line.strip() == "":         pass     else:         print line.strip()     if not line: break proc.wait() 

so need run subprocess , use readline function grab data output. print output stdout redirected text control. wx.yield() call allow text control updated in real time. otherwise, updated after subprocess finished.
