    <p>I am trying to run an executable and capture its output using <code>subprocess.Popen</code>; however, I don't seem to be getting all of the output. </p> <pre><code>import subprocess as s from subprocess import Popen import os ps = Popen(r'C:\Tools\Dvb_pid_3_0.exe', stdin = s.PIPE,stdout = s.PIPE) print 'pOpen done..' while: line = ps.stdout.readline() print line </code></pre> <p>It prints two line less than the original exe file when opened manually.</p> <p>I tried an alternative approach with the same result:</p> <pre><code>f = open('myprogram_output.txt','w') proc = Popen('C:\Tools\Dvb_pid_3_0.exe ', stdout =f) line = proc.stdout.readline() print line f.close() </code></pre> <p>Can anyone please help me to get the full data of the exe?</p> <h2>As asked by Sebastian:</h2> <p>Original exe file last few lines o/p:</p> <p>-Gdd : Generic count (1 - 1000)</p> <p>-Cdd : Cut start at (0 - 99) -Edd : Cut end at (1 - 100)</p> <p>Please select the stream file number below:</p> <p>1 - .\pdsx100-bcm7230-squashfs-sdk0.0.0.38-0.2.6.0-prod.sao.ts</p> <p>The o/p I get after running:</p> <pre><code>-P0xYYYY : Pid been interested </code></pre> <p>-S0xYYYY : Service ID been interested<br> -T0xYYYY : Transport ID been interested<br> -N0xYYYY : Network ID been interested<br> -R0xYYYY : A old Pid been replaced by this PID<br> -Gdd : Generic count (1 - 1000) </p> <p>So we can see some lines missing. I have to write 1 and choose value after please select the fule number below appears.</p> <p>I tried to use ps.stdin.write('1\n'). It didn't print the value in the exe file</p> <p>New code:</p> <pre><code>#!/usr/bin/env python from subprocess import Popen, PIPE cmd = r'C:\Tools\Dvb_pid_3_0.exe' p = Popen(cmd, stdin=PIPE, stdout=None, stderr=None, universal_newlines=True) stdout_text, stderr_text = p.communicate(input="1\n\n") print("stdout: %r\nstderr: %r" % (stdout_text, stderr_text)) if p.returncode != 0: raise RuntimeError("%r failed, status code %d" % (cmd, p.returncode)) </code></pre> <p>Thanks Sebastien. I am able to see the entire output but not able to feed in any input with the current code.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
