I found a good solution to this problem in Richard Steven's
_Network_Programming_. It seems like everything shows up in Steven's
books! Rather than pausing, you do a blocking read on a pipe. You
only write to the pipe from within the signal handler. However, this
brings up the better question:
I use the following
###
import re
Results=[]
data1=''
ID = re.compile(r'^.*=(\d+)&.*$',re.MULTILINE)
Results=re.findall(ID,data1)
print Results
#
to extract from data1 all numbers such as 15015,15016,15017
But the program extracts only the last number 15017.
Why?
Thank you

Hi all
I am using win32 odbc to connect to SQL Server. I have just started
using the 'bit' data type, which is a boolean type which can store 1 or
0.
This works with win32, but it returns '1' or '0'. Obviously I can
change it to an int, but it would be nicer and more correct if it
returned an int

Hi

Everything seems to be clear but the use of globals (defined in the module
