Hello!
I need to call an exe file (Windows XP) in my program. Up to now I used
subprocess (Python 2.6):
cmd = "bowtie-build mydb.fasta my_db_index"
startupinfo = subprocess.STARTUPINFO()
startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
startupinfo.wShowWindow = subprocess.SW_HIDE
subprocess.call(cmd, startupinfo=startupinfo)
Now I switched to Python 2.7 and also to win32process:
StartupInfo = win32process.STARTUPINFO()
StartupInfo.dwFlags = win32process.STARTF_USESHOWWINDOW
StartupInfo.wShowWindow = win32con.SW_HIDE processHndl,
primary_thread, pid, tid = win32process.CreateProcess(
None,
cmd, None, None, 0,
win32process.REALTIME_PRIORITY_CLASS,
None, None, StartupInfo)
In generally it's works but with a very strange behavior. In my program
I generate some data which are stored in text files and during the run
proceeded. But If I use win32process, I see the results of the previous
run in my output. If I start my program again and perform a new run
with new data, the results are always calculated with the previous
data. I do take care to delete data from the previous runs. I'm very
confused how this can happen. If I use os.system(cmd) or subprocess as
before, everything works as expected.
Can anybody can help?
Thanks in advance!
Stefanie
