You need to define stdin and stderr when calling a subprocess in windowed mode.
Example:
p = subprocess.Popen(["netstat", "-a", "-n", "-o"], stdout=subprocess.PIPE, stderr=subprocess.DEVNULL, stdin=subprocess.DEVNULL)
This is because windows tries to duplicate these handles if they're not set to null.

web2py Exception in sql rows

when i do the following code:
family_members =db(db.member.id == membership_id).select
(db.member.name,db.member.id)
family_members.colnames = ('Name','Membership ID')
It cause the following error...

P.S. : when i commented the line (family_members.colnames = ('Name','Membership ID')), it works fine, but I don't understand why.

Do not use colnames. That attribute is internal to web2py. Use db.table.field.label='..' or SQLTABLE(rows, headers={...}) depending on what you need.
