Hi,

I need to access the windows registry on an XP system.
In this way, I just write the following prog which do
the trick using the python _winreg module and the 
wxConfigBase class

---8<------------------------

import _winreg
from wxPython.wx import *

def GetParam () :
    # Open HKEY_LOCAL_MACHINE.  
    key =_winreg.ConnectRegistry (None, _winreg.HKEY_LOCAL_MACHINE)
    subKey = _winreg.OpenKey (key, 'SOFTWARE\\Jabber\\Exodus\\')
    infoKey =_winreg.QueryInfoKey (subKey)
    print infoKey
    value = _winreg.QueryValueEx (subKey, 'Install_Dir')
    print value

    _winreg.CloseKey (subKey)


def GetParam2 () :
    key = wxConfigBase (None)
    value = key.Exists ('HKEY_LOCAL_MACHINE\\SOFTWARE\\Jabber\\Exodus')
    print value


GetParam ()
GetParam2 ()

----8<---------------------------


which output is the following :

(0, 1, 126919629731703750L)
(u'C:\\Program Files\\Exodus', 1)
Traceback (most recent call last):
  File "reg.py", line 33, in ?
    GetParam2 ()
  File "reg.py", line 27, in GetParam2
    value = key.Exists ('HKEY_LOCAL_MACHINE\\SOFTWARE\\Jabber\\Exodus')
  File "C:\Python22\Lib\site-packages\wxPython\utils.py", line 29, in Exists
    val = apply(utilsc.wxConfigBase_Exists,(self,) + _args, _kwargs)
TypeError: Type error in argument 1 of wxConfigBase_Exists. Expected 
_wxConfigBase_p.
Exception exceptions.AttributeError: "wxConfigBase instance has no 
attribute 'thisown'" in <bound method wxConfigBase.__del__ of <C 
wxConfigBase instance at None> > ignored


It works when I use _winreg but using the wxConfigBase class seems
not to be as simple as I thought...

I start with python and I interpret the error as the 'Exists' methode
want something like a pointer ...

I think I missuse the wxConfigBase class but I don't find more doc than
the one in wxWindows that seems not sufficient for me :(

Did someone have tips, links, explanations or anything that could help me?

Thanks,
