I assume you have checked that comfunc equals peek4u(g_pVB)+#2C  (or 
something like that).
The last PUSH is interesting. I don't really understand where this parameter 
is aimed, but your code (below) doesn't seem to perform the extra push. 
Perhaps this param has something to do with Lock() being a virtual 
function..?  C++ isn't really my strong side so I wouldn't know.
