Hi!

I have done exactly like stated in 'HOW TO: Call a Managed DLL from Native
C++ Code' from Knowledge Base, but in my MFC application I have implemented
the tmain section in it's own MFC class. All is looking good until a call to
interfaced Method is done, then I recieve a negative HRESULT. Why?

Best regards,
Bertil Morefält

can you please provide a sample? did you compile your MFC application
with /clr?

i have a quick and dirty sample for you, but it does not use MFC or
interfaces. please be more clear about the problem.

Exactly what is the value of the HRESULT? If you convert it to hexadecimal,
you can search for it on google.

One "awkward" question; did you call CoInitialize() in that thread?
Does the object require MTA?
