Windows, Python and Strings

[Engel, Gregory]

I'm trying to update an NT/W2K service configuration (service written in Python) using win32service.ChangeServiceConfig.  The following code runs without error:

>>> import win32serviceutil
>>> scm = win32service.OpenSCManager(None, None, win32service.SC_MANAGER_ALL_ACCESS)
>>> svc = win32service.OpenService(scm, "TestQueueMgrSvc", win32service.SC_MANAGER_ALL_ACCESS)
>>> svccfg = win32service.QueryServiceConfig(svc)
>>> svccfg
(16, 2, 1, u'"D:\\Python\\Lib\\site-packages\\win32\\PythonService.exe"', u'', 0, u'', u'LocalSystem', u'Test Queue Manager')

So, I have a handle to the service and can retrieve it's current configuration.  Now I want to make this service dependant on MS SQL Server:

>>> win32service.ChangeServiceConfig(svc, svccfg[0], svccfg[1], svccfg[2], svccfg[3], svccfg[4], svccfg[5], 'MSSQLServer', 'LocalSystem', '', "Green Bar Queue Manager")

This also executes without error.  When I look at the Registry, the value shows as "M S S Q L S e r v e r" rather than "MSSQLServer" so the dependency fails.  If I use the MS tool, sc.exe:

sc config TestQueueMgrSvc depend= "MSSQLServer"

the Registry value correctly shows as "MSSQLServer".  I've tried a number of approaches to resolving this with no luck.  It doesn't appear to be a encoding issue.

The method requires a string parameter.  The Registry stores the value as binary data.  What am I missing?  Is there something I don't understand about how to use this method?

Many Thanks.

C'ya,
