Remote object call from COM component

[Dave]

I have an existing COM component written in C++ that does some Windows
account management stuff. We're moving to Active Directory and rather
than change the whole application, the only changes required are to the
COM component. I want to move the functionality of the COM component to
a remoted C# object, this is straightforward. I also want to make calls
to the remoted object from my original COM component. This is not so
straightforward.

I will confess to having very little experience with Interop. While I
wade through the documentation can anyone tell me whether I'm pushing
solid waste up hill? The code that is failing is the following attempt
to instantiate the remote object:

HttpChannel * channel = new HttpChannel( NULL, NULL, new
BinaryServerFormatterSinkProvider());
ChannelServices::RegisterChannel( channel);
#undef GetObject
IBranchUserLib * branchUser = dynamic_cast<IBranchUserLib
*>(Activator::GetObject(__typeof( IBranchUserLib),
S"https://myworkstation:443/BranchUserLib/BranchUserLib.rem"));

This code is based on the same code I use successfully in a C# test
harness but in this case it fails with error 8007000e (Out of memory
error.)

Any clue would be greatly appreciated. Thanks.

Please ignore this, I have resolved the problem. It was failing because
my test app didn't have a reference to the assembly containing the
IBranchUserLib interface.
