Hi Stephane,

I've tested your code in the following configurations:

1) WinXP, instantiation locally
2) WinXP client with CRETEOBJECTEX(), component on W2KSP3 Server

compiled and tested with VFP8 - no problems. Did you manipulate any of the default settings for the COM+ application or the component?

I've noticed one thing that IMO won't really matter, but to be sure:

Store NULL TO loCom, loContext

You could switch the order in which the objects are destroyed like so:

Store NULL TO loContext, loCom

>File: .\jit.cpp, Line: 78

hmmm ... jit = Just In Time Activation ... I've had this set to on, but no problem.
