win32com and Reflection2

[Roger Upole]

   I'm scripting Reflection2 sessions with win32com.client.Dispatch.
However, there are some constants (error codes, transmission modes,
etc) in a typelib that I can't seem to get at from the Dispatch object.
Anybody know of a way to access these from Python ?
   If not, is there any way to get to them from C++ ?
I have very little experience with C, but if it is simple I can
probably blunder my way through it.
