I have a curious problem. I use Tim Golden’s module for WMI, and I use the
‘StdRegProv’ to query a remote registry over WMI. I get an unusual network load
for this procedure.
Using a packet capture, I saw that each new query contains all the previous
ones.
Do I use the module in a wrong way?
Did anyone else encounter this problem?
Well I can simplify things for you slightly at the beginning:
<code>
import wmi
oReg = wmi.WMI (server, namespace="default", user=user,
password=password).StdRegProv
</code>
Also you might perhaps simplify your code by using tuple unpacking
and by exploiting the fact that in Python anything empty evaluates
to False including 0, None and "":
<code>
import wmi
server = "BLAH"
user = password = ""
oReg = wmi.WMI (server, namespace="default", user=user,
password=password).StdRegProv
result, subkeys = oReg.EnumKey( hive, key )
if result:
print "Couldn't..."
return
for subkey in subkeys:
result, name = oReg.GetStringValue( hive, key+'\\'+subkey, "DisplayName" )
if result:
print "Couldn't get display name..."
continue
result, ver = oReg.GetStringValue( hive, key+'\\'+subkey, "DisplayVersion" )
if result:
ver = ""
result, publisher = oReg.GetStringValue( hive, key+'\\'+subkey,
"DisplayVersion" )
if result:
publisher = ""
# ... etc.
</code>
Obviously more refactoring could be done to drop the common code
into functions etc. But I'm sure you knew that.
However I can't see any particular reason why each new query should contain
all the previous ones. Can you show an example of your network trace?
