out parameters in Python and COM

[Stefan Schukat]

You should use the makepy generated wrapper. The dynamic dispatch
does not support out parameters. 

So following should work:

from win32com.client.gencache import EnsureDispatch
 
atm = EnsureDispatch("ATM.Shell")
b4 = atm.LogOn("Administrator", "EHSW", "Python")
 
 
HEMgr = atm.ATMHeadEndManager
HEMgr.SetCodeTable("BS","ES","EE")
Ret, a, b, c = HEMgr.GetCodeTable("","","")
