I have an application where I need to pass the  data in a COLEStreamFile
object to a method of a .Net class which accepts Stream*. I had implemented
the solution specified in the following article in my application
http://support.microsoft.com/default.aspx?scid=kb;en-us;321340
But it doesn't compile and gives the following error
C2682: cannot use __try_cast to convert from 'LPSTREAM' to
'System::Runtime::InteropServices::UCOMIStream __gc *'

I can see only one difference in the actual implementation in the article
and in my application i.e I have not included any interop assembly. This may
not be the reason for the compilation error. Anyway I cannot figure out
which .dll or .tlb should be used to generate the interop assembly.

Any help will be appreciated.
