Well... Just look at the name of the computer you are sending the
message to. Its looking for a computer named 'ComputerName', not
'PC1' ...
You want to create a command that has the computer's name in it, like
this: 'net send PC1', not like this 'net send ComputerName'. You have
several ways to from such a string. You have the same problem with the
message. Your message will be the string 'Message' not the contents of
a variable names Message. Try:
os.system('net send %s "%s"' % (ComputerName, Message))
(where the % operator replaces %s's on the left with values taken from the
variables on the right)
or
os.system('net send ' + ComputerName + ' "' + Message + '"')
where the +'s build the command string up from pieces.
You might try invoking Python interactively and try typing some of these
expressions by hand to see that happens:
python
>>> ComputerName = 'Fred'
>>> Message = 'HI'
>>> print 'net send ComputerName "Message"'
net send ComputerName "Message"
>>> print 'net send %s "%s"' % (ComputerName, Message)
net send Fred "HI"
>>>
