Re: [Wrapper-user] Wrapping COM Server

[Georg S. <geo...@ti...>]

Jim,

just guessing: for some reason, when running from the batch file, both 
server and client run inside the same COM compartment, but when using 
the wrapper, they run in different compartments and therefore calls from 
the client to the server need to be marshalled.
