The previous examples were incomplete (and contained errors). Here is
a more complete example:


# pyreged.py

from myregedit import *
def main():
  "Main() function"

  key='LOCAL_MACHINE'
  subkey='SOFTWARE'
  myr = myregedit()
  keylist = myr.IterKeys(key=key, subkey=subkey)
  if (keylist):
    print keylist
  else:
    print "Unable to iterate keys"


if __name__ == "__main__":
  main()

# myregedit.py
import sys, string
from _winreg import *

class myregedit:

  def __init__(self, compname=None, debug=None):
    "Class initilization 'constructor'"

    try:
      self.LOCAL_MACHINE = ConnectRegistry(compname,
HKEY_LOCAL_MACHINE)
      self.CURRENT_CONFIG = ConnectRegistry(compname,
HKEY_CURRENT_CONFIG)
      self.CURRENT_USER = ConnectRegistry(compname, HKEY_CURRENT_USER)
      self.DYN_DATA = ConnectRegistry(compname, HKEY_DYN_DATA)
      self.PERFORMANCE = ConnectRegistry(compname,
HKEY_PERFORMANCE_DATA)
      self.USERS = ConnectRegistry(compname, HKEY_USERS)
    except:
      print "Unable to connect to the registry."
      sys.exit(1)
    self.reg = [self.LOCAL_MACHINE, self.CURRENT_CONFIG,
self.CURRENT_USER,
                self.DYN_DATA, self.PERFORMANCE, self.USERS]
    
  def IterKeys(self, key=None, subkey=None):
    "Returns type and data of a given value"
    mykey=-1  

    if (key is "LOCAL_MACHINE"):
      print "HEYU!"
      mykey = 0
    elif (key is "CURRENT_CONFIG"):
      mykey = 1
    elif (key is "CURRENT_USER"):
      mykey = 2
    elif (key is "DYN_DATA"):
      mykey = 3
    elif (key is "PERFORMANCE_DATA"):
      mykey = 4
    elif (key is "USERS"):
      mykey = 5
    else:
      print "unableto assign mykey any value other than -1"
      print "[%s]\t[%s]\t[%d]" % (key,subkey,mykey)

    if (mykey is -1):
      return None

    subkeylist = []
    try:
      i = 0
      while 1:
        subkeylist.append(EnumKey(OpenKey(self.reg[mykey], subkey),
i))
        i += 1
    except EnvironmentError:
      pass
    return subkeylist


-------------
Doesn't make sense to me, I've been banging my head against the wall
for several hours now! I can't figure it out.. and I know it's
something very simple that I'm overlooking. I just don't see staring
at it any longer to be productive :)

Thanks
